The July/August Technology Ireland carries an article on
numerical control of machine tools; this is of interest because the
type of engineering works which uses machine tools in Ireland is
usually concerned with small job-lots. Numerical control is a means
of using machine-tools flexibly; this involves an approach to design
basically different from that associated with the large-scale
production-line. This article, taken along with another one by Dr
Garrett Scaife of TCD on engineering design in Irish manufacturing
industry, strikes a hopeful note for the future of a nationally-based
engineering industry.
Dr Scaife raises very pertinently the question of the export tax
concessions, grants etc given to foreign firms. He suggests that
instead we should put the money into a national-based industry, with a
production process based on subcontracts and licences from abroad, to
earn the bread and butter, and to provide a working basis on which to
develop and build more locally-designed products.
He feels that the State should intervene to '...reduce the risk
of our becoming hewers of wood and drawers of water'.

The relationship between physics, chemistry and engineering is
subtle and complicated. Traditionally the engineers used to take as
given the properties of the materials that they worked with, and left
to the physicists and chemists the task of elucidating why they are as
they are.
There has been a trend from within engineering towards a more
fundamental approach.....which can be labelled 'engineering science';
this seeks to develop new materials or modify existing ones in the
light of an understanding of the basic reasons for their properties.
In the form of metallurgy this has been with us for many years;
the development of alloys has gone hand in hand with the study of the
solid state, unravelling of crystal structures by X-ray diffraction
analysis, and so on.
The development of synthetic materials by the chemists has
extended this field, so that the engineers are now as much concerned
about the fundamentals of non-metallic solids as they once were about
metallurgy.
Developments in this have tended to come from the engineers
rather than from the physicists, largely because of the preoccupation
of the latter with particle physics. This is a world-phenomenon which
is leading to redundancies among the physicists...
There is a nucleus of a good engineering science tradition in
Ireland; it is developing between TCD, UCD and the Dublin colleges of
technology; it has an unofficial, informal corporate identity
expressed in a meeting every Saturday morning during term-time. It
has been building up since about 1962 around the work of the Scaife
brothers in the TCD Engineering School. The two basic themes have
been dielectrics and high pressure.
'Dielectric effects' is a term which covers the behaviour of
non-conductors under electrical stress. They have considerable
economic significance in our daily lives; why, for example,should we
pay for electricity to heat up the oil in which the ESB transformers
are immersed?
Dielectric effects tend to be dominated by impurities in small
quantities. In the semi-conductor field, the study of very pure
germanium, with the introduction of tiny controlled quantities of
other elements, led in the late 40s and early 50s to the commercial
development of the transistor..... The technology of extreme purity
is now spreading from semi-conductors to dielectrics. Pye of
Cambridge have donated an induction furnace used for germanium work to
the TCD laboratory, where they have begun to use it to grow extremely
pure crystals of alkali halides for use in dielectric experiments.
....in a cubic crystal lattice...the behaviour of a dielectric under
mechanical stress can be studied in a manner uncomplicated by other
factors.
One of the significant relationships in the study of dielectrics
is the behaviour of the 'permittivity' (this is a measure of the
amount of electrical energy which can be stored per unit volume in a
dielectric) as the density varies. This must be done at constant
temperature otherwise the density effects tend to be masked..... one
is therefore led to develop an experimental technology of high
pressure...
Dr Garrett Scaife has developed a system where by the use of
hydraulic jacks it is possible to subject a specimen to 5000
atmospheres pressure, while making electrical measurements of high
precision on it. The pressure itself is measurable to within 0.1%.
The existence of this equipment has enabled diversification to
take place. The behaviour of liquid under high pressure is of
interest in lubrication..... a link with Queens University Belfast
has developed; there Professor Crosland had been measuring
viscosities of liquids by observing the speed of a falling plate by
electrical methods; this presupposed a knowledge of the permittivity
of the liquid under high pressure.....available from the Dublin work.
A link also exists with University College Dublin where Tom Gallagher
has been working on the electrical breakdown of solid argon of high
purity, introducing impurities in the form of helium atoms
(alpha-particles) from a radioactive source.....Brendan Scaife and Tom
Gallagher had worked together in Queen Mary College, London.
The link with the Kevin St College of Technology is two-way: Val
Rossiter(1), from Kevin St, did his MSc in TCD; Dr V Kanath, who did
his PhD in TCD is now at Kevin St., where works also Tom Ambrose, who
had previously worked with Brendan Scaife. There is a link with the
Dublin Institute of Advanced Studies, in that Brendan Scaife worked
there for a period on the theoretical basis of dielectric phenomena.
This link extends (rather tenuously, perhaps) into biology via the
ideas of Frohlich(2) (who) is trying to understand the functioning of
enzymes in terms of 'long-range order'; one of the experimental
techniques he has in mind involves the measurement of dielectric
effects in biological systems at various frequencies.....
There is also possibly a bridge to be built towards the polymer
chemistry people in Dublin....there seems to be the makings of a
useful 'centre of excellence' in this integrated yet diversified
group.....constituting a potential economic asset to the nation.....
April 7 1971
On April 2 the Minister for Industry and Commerce was presented
with the first volume of a directory produced by the IIRS which
enables one, at last, to find out who in Ireland can do a particular
operation, and who can produce a specified product (in the engineering
field).
For example, if I want to know who has a universal grinder I look
it up and find that I have to go to Holmes of Monasterevan, Cavan
Engineering, Tool and Guage Co (Tubbercurry) or Shannon Diamond and
Carbide. If I want honing/lapping I go to Colliers of Bunclody, Hayes
Bros or J Kelly in Limerick. Fabrication in stainless steel in the
Republic is done by APV Desco in Drimnagh, and apparently by no-one
else.
This promises to be a useful directory. All the other stainless
steel fabricators who are not in this first edition (because they
didn't reply to the questionnaire which was sent out, dismissing it as
another piece of administrative bumph) will without doubt leave no
stone unturned to get into the second edition.
There is also a section where each firm lists its total
capability. I am impressed by the large number of small firms away
from the main urban centres which have specialist engineering
capability. The existence of this directory cannot fail to get them
appreciable sub-contracting business.
This directory is the first of a series to cover textiles,
non-metallic materials, paper and printing products, and 'food, drink
and tobacco' (the latter being the triple group beloved of
statisticians, of which the disaggregated economics, for fear of
embarassing particular firms, must never be unscrambled!).
August 11 1971
Professor Hanrahan has sent me some material relating to current
UCD work on soil mechanics. I also have received a copy of the Scaife
monograph on complex permittivity, and some material on the Byrne-Lacy
electric car, as developed in the UCD Department of Electrical
Engineering, and reported in the February issue of Technology Ireland.
The UCD Civil Engineering work is a pattern for the development
of the relationship between the applied research institutes and the
universities.
Practical civil engineers are interested in the physical
properties of complex materials such as soil and concrete. From years
of experience they establish rules of thumb, empirical relationships,
margins of safety. Physical scientists have have developed measures
of properties of pure materials, such as the various moduli of
elasticity, creep coefficients etc, which can be used to describe the
behaviour of laboratory specimens under stress conditions.
It has long been recognised on both sides that measures such as
these are not adequate to describe the behaviour of many complex
substances of practical importance. There remains a wide gulf between
the laboratory and the construction site. This gulf is partially
bridged (in the case of complex substances for which the liquid phase
is important) by the science of rheology. This has illuminated the
fundamentals of the design of pumps and flow systems for slurries such
as liquid cement, or viscous liquids such as mayonnaise. One of the
key ideas in rheology is the existence of a viscosity (ie resistance
to flow) which is dependent on the rate of flow. One can have liquids
which become solid if you try to stir them, and others which become
solid unless you stir them.
Professor Hanrahan and his UCD group have looked at the 'nearly
solid' end of the spectrum and have carried out some fundamental work
on the stress/strain/time relationships in two-phase systems nearly at
rest. Waterlogged soil, and the movements in it due to the weight of
a structure, constitute such a system. They have managed to
unscramble effects due to change of shape under stress from those due
to change of volume. The latter being non-linear (ie equal increments
of stress do not bring about equal increments of strain), it follows
that the behaviour of a sample buried deep in the earth and under
pressure from the overlying material will be quite different if it is
taken out and tested in the laboratory.
Despite this, a system of measurement has been devised which
enables a set of conditions for 'zero lateral strain' to be
established. Theoretically this arises when the lateral displacement
due to 'change of shape' is exactly balanced by the volume decrease.
The system of measurement enables, from laboratory tests,
specifications to be laid down which will give zero lateral strain on
site, with considerable practical importance for the practicing civil
engineer and architect.
The next step is to develop a working system to be available on a
routine basis to civil engineers from the Foras Forbartha
laboratories.
The TCD monograph, just published, contains review articles
covering the theory of dispersion in polar dielectrics, the
experimental position as regards the effect of high pressure on
dielectric properties, and a review of the experimental techniques.
The authors are BKP Scaife, WGS Scaife, RG Pennett and JH
Calderwood.. The latter two are in the University of Salford.
Professor Calderwood(3) is the editor of the series. He delivered a
polished philosophical lecture on engineering in Dublin some 18 months
ago.
Let me attempt to explain to a lay readership what the problems
are.. In contrast to the Hanrahan work, the Scaife work is concerned
with electrical stress under vibratory conditions, rather than
mechanical stress under static. As you increase the frequency of
vibration, different effects become important (the inertia of the
molecules, dipole coupling etc). One theoretical approach is to
consider one molecule embedded in a uniform sea of its neighbours;
this approximation however is no good at certain frequencies where
collective effects, involving interactive groups of molecules, exist.
The experimental work consists in making accurate electrical
measurements on specimens under high pressure. It has associated with
it various levels of approximate theoretical treatment. The
measurement techniques are adaptations of various classical bridge
methods at the lower frequencies, with wave-guides etc becoming
important at high frequencies. The gap between the infra-red and
millimetre-wave RF remains the problem area.
It is good to see a theory-experiment interaction producing
monographs for the international market emerging from a basement in
Lincoln Place. The spin-off in terms of high-pressure technology in
Ireland, however, is unlikely tobe of any great economic significance.
More valuable is the output of trained applied physicists, or
engineering scientists, who have been through a tempering-process in
the research-crucible. Such people should be able to turn their minds
to more generalised problem-solving, and in proportion as they do they
can become an asset to economic life in Ireland.
The trouble is, however, that employers might think that they are
'high-pressure electrical measurement specialists' and be put off.
The people concerned might even be themselves under this illusion.
There is here a marketing job to be done.....
August 25 1971
...On August 11 owing to pressure on space (due to the Northern
situation) the second UCD project got dropped.....I now return to the
electric car as developed by JV Byrne and JG Lacy in the UCD
Electrical Engineering Department.
There is nothing new in this; electric cars have been with us
for 50 years or more, and are commonplace in the form of the milk
float. The problem is to get an acceptable performance in terms of
speed, acceleration and range.
The 'Byrne-Lacy Special', by dint of careful design, low-loss
tyres (there is a skid-liability here) and an aerodynamic body, has
shown itself capable of holding its own in moderately fast city
traffic (32 mph). The key idea is the use of a thyristor-chopper
control system, which is low-loss compared to the traditional
rheostat, and allows regenerative braking.
This is excellent training for the research students, who will
emerge knowing something about the practical problems of electrical
control systems. It is not aimed at the marketplace. If an electric
car comes on the market, in all probability it will be as a result of
a decision by a major producer to go into mass-production.
It could be argued however that the major producers have too much
capital tied up in conventional automobile production systems, and are
unlikely to have their heart in electric car development. In this
case, there may be scope for a flea-size manufacturer to jump in and
survive, using readily available standard elements to produce a robust
job with no frills and absolute reliability.
The market would be basically urban; it could be expanded by a
State or municipality decision to ban noise and fumes in the inner
city.
Much of the cost of conventional vehicles comes from the
frequency of style-changes. According to Ralph Nader, only 3% of the
so-called 'development costs' of the US 'big three' goes on improved
performance. The rest is eaten up by restyling. It follows that a
firm which tooled up for a 20-year run, and wrote off the plant over
this period, could be viable on a substantially smaller scale than is
customary in the industry. Such a firm could scoop the market if the
design was aimed at durability rather than for obsolescence. The firm
would recover its money by refusing to sell, only supplying on a lease
basis with a maintenance contract. Old cars which continued to run
reliably would be the cream of the contract, and the firm would have a
visible vested interest in reliability.
A basic utilitarian unit turned out by such a manufacturer could
be invested by the user with his or her own aesthetic ideas, either
employing a craftsman or on a 'do-it-yourself' basis. Hand-carved
interior panelling, psychedelic painting, anything goes. Students are
already into this art-form with their bangers. The large
manufacturers who go in for highly variable 'aesthetic' styling have
missed the point.....all they succeed in doing is making an unreliable
product, for the variable appearance of which the consumer is forced
to pay.
The urban transport and amenity problem, however, will not be
solved by unleashing another piece of hardware on it. It is a
'systems' problem. There needs to be positive control excercised, in
the social interest, over the ratio of public to private seat-miles
for the urban journey, and over the distribution of urban journeys.
If everyone lived within walking distance of work there would be no
problem. Transport cannot be considered in isolation from urban
planning.
To return to the 'Byrne-Lacy special': there is a case for
asking the IIRS to look into the techno-economics of an Irish
manufacturing industry for a small standardised electric car, and
estimating how the market could be influenced by tightening the
environmental laws.
There is scope for the 'hybrid vehicle' in the public transport
system. Consider: the average power consumption of a bus is about 10
HP; a small petrol or diesel motor running at a constant optimal
speed could supply this power very efficiently, quietly and without
significant pollution. An associated storage-battery/electric
traction system, with regenerative braking, could be designed to carry
the peak loads, buffering the variable power demand against the
constant charge-rate. Such a system would be an immediate asset to
urban transportation in Dublin. Over now to the electrical and
mechanical engineers.
November 22 1972
...To give an example of the kind of problem solved by the SPS
lab at Naas(4): consider a nut-making machine which cold-forms a
slice from a rod into a hexagon, turns it over, positions it, drills
it, taps it etc. This sequence of operations involves precision
operations with mechanical 'fingers', interspersed with high-powered
operations involving tool steel. Slight wear of moving parts can
cause tool breakages, due, for example, to the machine attempting to
punch holes in its own 'fingers' instead of the blank nut. The
traditional (purely mechanical) system used to spend 25% of its time
under repair.
The SPS people have linked up the system with some electronic
position sensors, feeding the signals to an on-line computer, which
works out continuously the statistics of the deviations of the
movements of the powered moving parts from the norm. By a feedback
system, the settings of the power tools are continually adjusted so as
to allow for wear. Thus an old machine, with 'intelligent' control,
can be made to look like a new one.
Another machine counts nuts and bolts as they pass through a
multi-channel sensing system, in a veritable avalanche, hundreds per
second; this is a further example of harnessing electronic tricks in
mechanical problems. The technique of pulse-counting, with a
proportional principle to allow for 'doubles'and 'trebles' was
developed by the nuclear physicists in the 50s and 40s; the embryonic
principles needed existed in the 30s in the Cavendish Laboratory in
Cambridge. Engineering systems like this became practicable in the
60s, when the widespread availability of solid-state devices made the
circuitry reliable. Thus physics continually feeds engineering.
This machine was a prototype developed in Naas for use in SPS
factories. No doubt it would have a ready sale on the market.
Other projects involve noise-reduction in machines (for health
reasons), automatic tensioning of nuts and bolts: anyone who has
tightened a small nut with a large spanner will know the problem. SPS
have invented a device which tightens until it feels the onset of
non-linear strain. They also have non-destructive testing of surface
plating thickness and quality (by electronic means), fracture
analysis, analysis of alloy composition and so on.

I publish today an article by Dr W J Chambers(5) which outlines
some of the technological implications of the scanning electron
microscope.....
Some may complain that Dr Chambers' article makes hard reading.
It is no harm that this is so; it will perhaps help to bring home to
people the fact that there is a big gulf between the level of
technological potential in Ireland, and the level of understanding on
the part of the industrial managers who have to make the decision to
devote resources to the use of new technologies. This cultural gap is
the central problem of Irish economic survival. People are
increasingly aware of it, but no decisive moves are being made to
bridge it.
This awareness shows up in events such as that sponsored on May 8
by the IEI Electrical Division.... Here a panel of young engineers
gave their preliminary impressions of their jobs, with comments by
more senior people....
I detected a suggestion that the way to take up the potential of
the trained engineer was to broaden him(5a) away from pure
professionalism and get him into management. The young engineer who
does not shirk a foreman-type assignment in his early days is more
easily able to make the transition. The engineer in management is at
the core of Continental technological superiority; British decline is
due to gentleman-amateur managements keeping their trained expertise
in professional boxes.
An engineer trained in systems theory should have no difficulty
in identifying a balance-sheet with a state-vector and a
profit-and-loss account with the associated transition matrix. If he
turned his mind to it, he could revolutionise the accountants' craft
and make it scientific.
Our industry will be unable to take advantage of the type of
expertise displayed by Dr Chambers until there is a substantial
increase in the technological knowledge of, or available to, those
responsible for industrial decision-making.....
May 8 1974
A new type of co-operative venture between university and
industry is at present under way. The firm is the Pennsylvania-based
Standard Presses Steel Corporation, which has two plants in Ireland,
one at Shannon and the other at Galway, as well as a research
laboratory at Naas. There are also plants in England and Germany.
The university component in the venture is the Trinity College
Engineering School.
Some time ago SPS decided that it needed to recruit a group of
engineers to work in its various plants engaged in the forging
process. Engineers with suitable academic training and relevant
practical experience are not easy to find, so it was decided to train
a group specially for the purpose. As plans were worked out, it
became clear that SPS itself could handle the practical technological
element on the training programme within its own resources in Ireland,
but some help was needed in the teaching of the fundamentals of
process metallurgy, metal forming and fastener design.
It happened that at the same time the TCD Engineering School has
initiated a new form of masters degree, the MAI (recurrent
enducation), which was especially suited to the needs of engineers
working in industry.
Discussions took place between Dr W G Scaife, Registrar of the
Graduate School of Engineering Studies (TCD) and Dr Paul Wallace,
Director of the SPS Research Laboratories. In a very short time it
was possible to supplement the lecture courses normally available for
masters degree students with specialist lecturers from other
institutions.....(such as) the universities of Salford and Manchester,
the National Institute of Higher Education in Limerick, and the
College of Technology, Bolton St.
Altogether twelve students are taking this course...each of them
jointly supervised on their project reports by one engineer from the
university staff and one from the SPS Laboratory at Naas. Three of
the 12 are US graduates, two from Britain, one from Northern Ireland
and the remainder from the Republic.
So far this novel venture has gone smoothly(6)..... Moreover it
is felt that the way has been shown whereby other industries could
have access to a programme of advanced technological training based in
Ireland, of a calibre normally only available at Institutes outside
the State.
May 22 1974
..Griancloch Acla Teoranta is a small firm manufacturing quartz
crystal units for frequency standards and telecommunications filters.
It is located in an old schoolhouse at Dooega, Achill.
The firm is a joint venture between the directors and Gaeltarra
Eireann(7). The managing director, Jim Gilson, learned the technology
of growing high-quality quuartz crystals in the US, where he worked
with Western Electric. The process involves a closely controlled
3-month operation at high temperature and pressure, starting with
seeds correctly cut along the appropriate crystal planes, a step
requiring X-ray techniques. A power failure of more than 20 minutes
would be disastrous; in Achill this means standby generators(8).
When grown, the crystals are cut (again using X-ray techniques to
determine the alignment) into wafers, lapped to a close tolerance and
in some cases given a bevel edge. The modes in which the crystal will
oscillate are determined critically by this edging procedure, as well
as by the dimensions.
Electrodes are deposited on the surface by vacuum-evaporation of
silver. The fine-tuning of the frequency is done by etching away some
of the evaporated film, or by electroplating on some more.
The crystal oscillator finally is mounted in a little can, in an
atmosphere of nitrogen.
All this rather crafty technology is done by what Jim Gilson
readily admits are 'cook-book' procedures; these however have been
skilflly and effectively absorbed by local labour. Mr Gilson's own
background being in crystal-growing, he is dependent for know-how
about the frequency control unit on Mr Earl Clark, who is the retired
president of the Clarke Crystal Corporation....
A link with the University of Dublin (Trinity College) has begun
to develop....through the TCD Industrial Liaison Office(9).
Dr Malcolm Stephenson, who has a prior interest in quartz
oscillators from the angle of ultrasonics, spent an overlap period
with Earl Clarke; now they are looking for a physicist to join the
team, working at Achill initially on basic management and quality
control, and ultimately on various related technologies which will
branch out from the present base. He or she would register for a
masters degree with the TCD Engineering School..... a sort of
graduate apprenticeship scheme.......a good means of solving the
problem of the honours specialist graduate surplus.
September 25 1974
The sale of £90,000 worth of feed-mix computer to Japan,
announced on September 9 by William Marshall, Chairman of Qeleq ltd,
constitutes a further success for this dynamic Dundalk firm(10).
Also the current issue of 'Export', the Coras Tractala(11)
journal, notes the installation of a Qeleq feed-mix computer in
Winnipeg, at the International Grains Institute. It also carries a
photograph showing a Qeleq machine being evaluated by the Mixed Feed
Industry in Sofia, Bulgaria.
The secret of the success of this product is that it was tailored
to fit the needs of the person with the problem (the feed-mix
compounder). The level of electronics techology in it is not high;
in principle the machine could probably have been made prior to world
war 2, and certainly in the 50s (depending as it does on simple
analogue circuitry).
The lesson to be drawn from this success is that people in the
electronics industry should not necessarily always be making cleverer
devices to do existing jobs faster, but instead should be seeking new
applications where electronic systems are currently unknown, or else
have a name for unreliability due to a premature false start. Also,
that the art is not in the electronics itself, but in the structure of
the interface between the user and the machine, which must reflect the
structure of the problem.
April 15 1975
The IEI seminar 'Prospects for the Electrical and Electronic
Industry in Ireland' (April 10) constitutes a useful entrepreneurs'
guide...
Joe Beirne (IDA)...led off with a survey of growth in Ireland
against the world background. Currently in Ireland the sector has an
annual growth rate of 40%....
Electronics is intensive as regards labour and skill; most of
its capital in in the form of research and development.....indigenous
spin-off of linked industries is becoming increasingly possible as the
range of products manufactured increases....
Mr C Hyland (Unidare ltd) gave an electrical equipment
manufacturer's view.....a greater need for strategic planning at the
firm level and at national level, the link being the national housing
programme...
Mr L Murtagh BSc (Ecco, Dundalk) covered the electronic
manufacturing field.... it is bad strategy to price low so as to get
volume, in the hope of recovering profitability by reducing
unit-costs. The component-appliance system has exhibited classical
cyclic behaviour, due to interaction of stock levels and order
lead-times. (Forrester's 'Industrial Dynamics' is good background
reading for understanding this phenomenon; farmers familiar with the
'pig cycle' will also recognise it!)....
Mr Murtagh called for national laboratory support for the
industry, including providing means for qualifying to European
standards. This means, in effect, developing the IIRS electronics
capability. He also called for expenditure on expertise in the
universities and colleges, including R and D activity on components..
Support could come for this from the industry itself.
Mr P H O'Connor (ESB) deplored the tradition of having 'one-off'
control packages 'thrown in' with mechanical systems, without adequate
electrical engineering expertise, and suggested '......that the branch
of electrical engineering based on the assembly of control equipment
had the potential for a very bright future....'
Mr Don C Platz (Jacobs International) usefully gave the large
prime contractor's view of sub-contractors tenders: '....a proposal
which is incomplete receives only a cursory glance......we are not
happy to extend closing dates.....real shortage of qualified sales
engineers...who can answer engineering questions...'
Mr MJ McSweeney (McArdle, MsSweeney, O'Malley and Associates)
produced a useful list of import substitutions.....
Mr A Mullen (Department of Posts and Telegraphs) predicted a
switch to 100% digital systems by the year 2000(12)....
The proceedings contain a survey of the assistance available for
the development of the industry, prepared by Mr NF Meghen of the
Confederation of Irish Industries....covering fifty or more services,
including technical assistance which is 'exploded' in the following
section by Tom O'Connor of the IIRS....
In the session on export marketing, initiated by Mr PJ Delaney
of Coras Tractala(11), there followed a discussion in which two
distinct philosophies emerged: (a) don't sell the know-how, keep it
dark and sell the product (Winn Technology, Cork) (b) sell the
know-how (Cantrell, Unidare; this tradition is also well-established
with Aer Lingus, Bord na Mona etc, and is currently developing with
the ESB.
A straw poll by Russell Winn, who chaired the session, showed
that only about four people in the audience of 60 had been abroad to
meet their customers this year. Perhaps this reflects the gulf
between the engineers and the market, rather than their firms and the
market.
There was a strong reaction against the 'customs clearance
racket' and the paper barriers which were impeding the alleged free
trade system.
Finally Mr WIB Macken, of NIHE (Limerick) launched a polemic
against the Irish educational system: '...an artificially created
dividing line between....training and education delayed the birth of
the industrial revolution.....there are still institutions which claim
to be involved in, and strive for an exclusive commitment to, one or
the other...'
He instanced cases where he himself had earned consultancy money
trouble-shooting in a situation where an electrician, if properly
educated/trained would easily have done the job.....
Mr Macken called on employers to stop requiring City and Guilds
qualifications and to support our own NCEA(12a) awards, lending weight
to the Regional College programmes, over which Irish industry had
influence...
The Electrical Division of the IEI is to be congratulated on...a
historic and significant event....a seminal point in the growth of a
cohesive Irish electrical and electronics industry....
May 27 1975
People attending the Telecommunications/Pye(Cambridge) exhibition
on May 8-9 may have picked up a brochure entitled 'cost-effectiveness
of radio telephones', in which after some reasonable arithmetic it
emerges that twelve minutes of time saved per day, for a 2-tonne
lorry, pays the cost of the radio.
This interesting statistic underlies the proliferation of VHF
communications systems now to be seen on taxis, buses, lorries, vans.
Telecommunications in its Finglas factory have established a
creditable niche in the world market for this type of equipment.
One piece of equipment originally developed in the Finglas
laboratories and now manufactured by the Pye/Philips group is the
RZ502, which is a 1kW single sideband HF transmitter. This has
widespread civil, marine and aviation uses in Africa and Asia, where
reliability and ease of maintenance are important. Another Finglas
development is the A100 Transmitter/TC8 Combiner, which constitutes a
system capable of driving eight non-interfering discrete channels, at
25 watts per channel, through a single broad-band antenna. This, as
well as keeping down structural costs, is kind to the urban sky-line,
which, now that piped TV is coming in, has a chance to revert from its
present prickly appearance towards its pristine uncluttered roofscape.
What the Finglas people are most excited about, however, is their
new 'low-profile antenna' for vehicles.
As a consequence of the Unidare connection, and the ready
availability of aluminium alloys, Telecommunications have established
themselves as antenna specialists. There is a series of
vehicle-mounting antennae with the trade-name 'Finglas'.
Two problems are (a) car-washing and (b) vandalism. A partial
solution to the first is to slope the antenna, or make it easily
removable. The latter expedient, of course, adds to the second
problem.
Sloped antennae are, however, biassed as regards direction.
Communication fades as you turn a corner.
The new low-profile antenna works on a different principle: it
is, electrically speaking, a radiating slot, which sits flush with the
roof, housed in a PVC radome. It gives true omni-directional
radiations in the horizontal plane, and has a band-width 165-174 MHz.
Below 150 MHz it will work on two distinct adjustable frequencies. This is
a qualitatively new principle in VHF antenna design, the first in many decades.
CIE have purchased 100 units for their Cork bus fleet; export orders are booming.

Electronics firms in Ireland will be interested to learn of the
establishment at Craigavon of a subsidiary of the Andus Group, which
originated in 1963 in Berlin as a final-year student enterprise, and
now consists of seven associated companies.
The financial side of the operation has been covered by Ronnie
Hoffman on June 18; it remains for me to fill in on the technology,
mainly from the point of view of potential purchasers of printed
circuit boards (PCBs) in the industry.
The process begins by translating the wiring of a development
engineer's 'breadboard' prototype into a realisable design for a PCB.
This is a non-trivial problem, to the solution of which the branch of
pure mathematics known as topology has contributed. It is usually
resolved with the aid of a computer....
The prototype development work is done in Berlin, mainly; there
is however some capacity for it at Craigavon.
The design is easier if you are allowed to use both sides of the
board, although then the production becomes more exacting, as you have
to drill holes through the board and establish an electrical
connection.
This more exacting technology is carried out at Craigavon....
....Quality-control procedures are important; unless there is
error-detection at a number of crucial stages, each board would have,
on average, about one fatal flaw, rendering the bulk of the production
useless.
The draughtsman's art-work is photographed.....the film is
touched up manually, under magnifiers, and then used as the master for
the photoprinting process. A copy is also taken and used to produce a
computer-tape for controlling the drilling of the holes.
The production of this computer-tape, which carries numerically
the co-ordinates and dimensions of the required holes, is carried out
on a device which can trace a direct line of descent from the
high-energy nuclear physics laboratories of the late fifties(13), an
example of 'spin-off' from basic science into industrial technology.
Using an optical display of the circuit print (the latter being
mounted on a servo-controlled stage), an operator homes in on the
positions of the holes, pressing finally a key which causes the
co-ordinates to be written on tape. With this information on tape, it
is possible for a numerically-controlled drill to complete all
necessary holes in a typical board in about 20 minutes; a man working
by hand would take about 14 hours.
The drilled board is then given a close visual inspection; any
fault in a hole would interfere with the subsequent deposition of a
conducting layer on the inside.
Plating then takes place; initially copper is deposited
chemically, then electrically. This is to provide through-hole
conduction only; the circuit is not yet on the board. A blank PCB
consists of a thin sheet of phenolic or epoxy resin, coated on both
sides with copper (and of course on the insides of the holes).
A negative of the circuit is then deposited on the board,
covering all the conducting surfaces except where the final circuit
will be. The board is then placed in a plating bath, depositing a
tin-lead mixture on the exposed copper. Subsequently the printed
surface and the exposed copper is etched away, leaving a circuit of
which the 'wires' consist of copper strip with a layer of tin/lead on
top.....
....We can welcome the establishment in Ireland of this important
technology which is contributing to the reduction of the cost of the
basic equipment for satisfying human needs.....a board about one foot
square with 1000 holes and countless interconnections in an order of
1000 would cost about £17 per unit....replacing some tens of
man-days of traditional wiring. In prototype lots of 5 the cost goes
up to about £45; this goes up to £100 if you want a 3-day
delivery. This year in May the minimum order was 50, the maximum 2000
and the mean order size was about 400. So we are not dealing with
huge-scale production, such as to be above any interest in the Irish
market.
Normal order-times are 6-8 weeks; rapid deliveries of small
orders are possible at increasing premiums....
I think the electronics industry in Ireland will find it useful
to have this service on its doorstep.
July 1 1975
Arising from last week's feature on the Andus PCB factory at
Craigavon, I have had a communication from MJ Doherty, of CESCOM
electronics, London, pointing out that they are supplied with
excellent PCBs by Shannon Circuits ltd in County Clare, at a more
competitive price than suggested in my final paragraph for the Andus
product.
This suggests to me that we are in the presence of one of the
consequences of the 'export tax relief' and 'tax haven' policy which
has supported the Shannon development.
These policies, while appearing to help the balance of trade,
militate against the development of cross-links within the Irish
economy.
...A man with a lorry could make a good living driving Andus
products to Shannon PCB users, getting full return loads of Shannon
PCBs for users in Northern Ireland.
I wonder how much of this is going on, to the advantage of the
container-handlers(14)?
September 2 1975
The news that an Bord Gais propose to engage the British Gas
Corporation as consultant, and possibly as main contractor, for the
construction of the Gas Grid has incurred the wrath of the Amalgamated
Union of Engineering Workers, who have written a sharp letter to the
Minister....urging that this work be carried out by the ESB, whose
engineers have accredited consultancy status with the World Bank and
have done consultancy work abroad.
The letter points out that the tendency is for foreign
contractors to sub-contract to firms that they know, passing over
local engineering firms who would be competent and known to an
Irish-based prime contractor.
In the present recession, the letter points out, the sending
abroad of a major engineering contract well within the competence of
the ESB engineers would be a national scandal.
The project would not be a major one by ESB standards, and most
of it would be conventional engineering practice. The ESB has
considerable engineering experience in related fields (British and
international codes, surveys, wayleaves, advanced pipework technology,
welding quality control......)
One of the ESB's transmission projects involved the laying of a
ten-mile gas pressure pipeline from Poolbeg to Carrickmines, across
part of Dublin Bay and built-up parts of Dublin City. Also, the
penstock in Turlough Hill, which is sixteen feet in diameter and laid
in a tunnel through a quarter of a mile of solid granite, was
engineered, purchased and quality controlled by ESB staff. Current
engineering work being undertaken by the ESB includes a pressure
pipeline one and a half miles long across the Shannon.
The ESB might possibly require specialist consultancy services on
areas like safety codes and specialised instrumentation; these would
be a small proportion of the total project, and could easily be
acquired...
September 23 1975
A report by James Kenny of the UCD Science Policy Research Unit
at Belfield has come to hand. I have seen no evidence that this has
been studied or acted upon by any section of the ailing vehicle
assembly industry, but it seems to me that the Kenny Report, if taken
up by the latter, could be used as a guide to the redeployment of a
labour-force with relevant skills.
In 1970, £17M worth of agricultural machinery was imported
and £2M worth manufactured in Ireland, by an industry employing
940 people. Eight firms account for 80% of this production; of these
perhaps the best known are Pierce of Wexford, Kilkenny Products and
Armer Agricultural Machinery.
If combine harvesters, tractors and powered equipment are
excluded, the value of imports competing with home production is 5.8M
(34% of total imports).
Comparing the agricultural machinery sector with total metals and
engineering performance, the gross output of the latter in 1972 was
234M of which 60.7M were exported. Competing imports were 64M, giving
an adverse balance of 3.3M. The adverse balance for the agricultural
machinery industry was 17M, related to a miserable 2M home production.
Within this neglected sector one firm, the Irish Sugar Co, shows
a good export growth, from 40,000 in 1967 to 468,000 in 1972,
representing 56% of all exports.
There are given detailed comparative statistics of the relatively
thriving British industry.
Product development policy of the industry is criticised, and the
weakness of its design effort exposed (there are one or two promising
exceptions). Few qualified engineers are employed. Only two firms
have ever made use of the R&D grants available from the IDA.
There is a chapter outlining how the Polish industry was
transformed by licencing-in proven designs from Germany and
Czechoslovakia.
The report poses a number of explicit questions to the Department
of Industry and Commerce, recommends study of the industry abroad as
regards development strategies, vertical and horizontal linkages etc,
and advocates licencing in powered unit designs for manufacture in
Ireland.
There is a developed agricultural engineering section in AFT and
a Department in UCD which has done good innovative work.
The initiative in drawing these elements together, and
cross-fertilising them with the moribund vehicle assembly industry,
could well come from the Institution of Engineers of Ireland.. The
increasing pool of redundant motor assembly workers will no doubt view
developments with interest.

September 30 1975
The automatic aerosol valve, which has been under development in
the IIRS for some years (figuring in the annual reports as a promising
line of development), has now reached the stage of being a
fully-engineered useful product in search of large-scale production
and marketing.
...The essential patentable elements in the device have been
covered in fifteen countries.
The existing technology for dispensing automatically an aerosol
into an environment at a controlled rate involves electric motors,
cam-timers etc, a somewhat 'brute-force' approach which however has
been implemented...
The IIRS 'Autosol' device dispenses with the electrics; it
consists of a clever valve which clicks open or shut depending on the
pressures in associated chambers fed by a bleed of vapour from the can
itself.
The valve itself costs 35p; complete with charged can and
filling for six weeks supply it could sell profitably for £1.
This is comparable to the cost of the recharging operation for
existing 'brute-force' systems.
Pilot manufacture of some thousands has checked out a production
process involving precision injection moulding of plastic components.
A cash flow projection suggests that any firm having the
appropriate production and marketing resources would be unlikely to be
out of pocket by more than 100,000 pounds during the build-up phase;
the market is estimated to build up to 3M units per annum.
The problem is to combine the production, marketing and finance.
The production element, which would involve about 100 jobs, would
require expertise in precision moulding and light assembly. The
marketing element would invlve the ability to approach at senior level
a relatively small number of service-type firms (eg hotel
suppliers)... A consortium of two existing firms and a bank seems to
be suggested....(15)
October 14 1975
Two significant recent events were the IEI conference on offshore
engineering (October 2-3) and the launching by IIRS on September 23 of
a Directory of Suppliers to the offshore industry.
The proceedings of the IEI conference are available..... I came
away impressed by the account given of the art of fabrication and
moving of 500-ton accommodation modules, by G van der Puil, mamaging
director of Verolme Cork Dockyard ltd.
The loading of a 500-ton unit on to a barge, without a crane,
making use of the tide, a winch and some calculations, came over as a
remarkable feat of engineering craft.
Mr van der Puil made it clear.....that there was plenty of room
for sub-contracting, even by inland firms.
In the discussion there emerged a sense of urgency with regard to
the problem of job demarcation in the construction industry. This
has, I understand, largely been resolved in Verolme, where there is
developing a breed of multi-skilled shipbuilding technicians, on the
continental and Japanese pattern, as distinct from the British pattern
where the jobs are done by demarcated trades. This is a problem that
the Trade Unions are ultimately going to have to face, as the supply
of fabrications to an offshore system depends on meeting deadlines
with precision. One deadline missed and you are 'out' for good. The
firms listed in the IIRS directory must be uneasily aware of this; if
they are provident they will be looking into how to use the various
'critical path' systems that are available from the management
consultants, operations research people etc....
Justin Keating (Minister for Industry and Commerce) when opening
the conference...pointed out a weakness: lack of experience in
project management involving teams of complementary specialists. He
also suggested that the need for 'undersea completion' constituted an
opportunity....for developing the ability to work on the sea-bed
effectively, a field to which Winn Technology in Cork has contributed.
Some weeks ago in 'Technology Ireland' BEW Dowse of London
University put forward the concept of an oil rig consisting of a sand
island enclosed in a flexible bag, kept stable by controlled
hydrostatic forces. It would be capped by a concrete oil-tank
carrying the usual modules; this would be floated out and the island
built up under it, using suction dredgers.
This is an extension of the type of reinforced-polymer technology
which is the basis of projects such as the Thames barrage and the
level-control system for the Venice lagoon. Model tests are currently
in progress.
In proportion as concrete plays a key role, Irish offshore work
can utilise native resources. In current practice, concrete
structures are essentially shallow-water, gravity-anchored (like the
Kish lighthouse). Deep-water steel structures require a pile-driving
operation which is highly weather-sensitive, tying up expensive
equipment. If concrete top-structures could be combined with
sand-island technology, we would bring most of the engineering within
reach of Irish firms.
October 28 1975
One firm which reacted positively to the energy crisis was Duffy
Insulation Products ltd of Ardfinnan, Clonmel.
Originally a mineral water bottling plant, this firm is now
supplying the building industry with fibreglass insulating material,
in densities ranging from board (96 kg/mcubed) to light-weight
cotton-wool-like substances (10 kg/mcubed).
The idea arose out of the feeling that there ought to be some use
for broken glass, an inevitable by-product of a bottling operation.
So they bought the rights to a process developed in Britain, and set
up a plant capable of melting the glass, blowing it into fibres with a
blast of hot air; these then lie at random across a conveyor, like
candy-floss. A resin bonding-agent is added, and the product is then
compacted to the required density.
Although this is a relatively simple process, there is
considerable know-how involved in achieving a consistent product of
the necessary high quality....
Unfortunately the key factor is raw material composition, and it
turned out that bottle-glass was too variable. So Duffy's Mineral
Waters still throw away their scrap, and Duffy's Insulation products
buy in scrap glass from an electric bulb factory; this has the
necessary high quality.
Thus although the original objective of consuming waste has not
been achieved, a viable spin-off industry has been set up which is
riding the crest of the wave of consumer demand created by the energy
crisis....
Another product on which they have their eye is rock-wool, made
by applying a similar process (though at higher temperature) to
basalt, which is widely available in Co Antrim. A little basalt goes
a long way; rock-wool, like glass wool, is mostly air.
There is scope for invention to cope with the original desired
raw material: broken bottles. Could not the quality variations be
taken up with a feed-forward control system, based on signals from
appropriate instrumentation? The technology for this is available,
and the price of on-line computing is rapidly coming down....
***
I have to hand a report produced by NG Marchant of Kilkenny
Design Workshops which makes the case for the establishment of an
adequately staffed and equipped industrial design service orientated
towards the engineering-based manufacturing industries.
It is still, apparently, necessary in Ireland to explain the
distinction between industrial design and engineering design. The
former art is is necessary for the translation of the solution of a
problem into the specification of a system which will create the
necessary utility at an acceptable cost. The latter, which is perhaps
more of a science, concerns itself with the technical performance of
the system so specified. There is more to industrial design than
putting the engineer's 'gubbins' into an acceptable box. An
industrial designer would normally work as a member of a design team,
with special responsibility for the relationship between the product
(or system) and its user.
In the report is a list of firms which would constitute a market
for such an operation. This is compounded from various guides.... It
emerges that the IIRS guide is about 60% complete, missing major firms
like Telectron. (It is surprising the resistance that people have to
returning a questionnaire, even when it should generate business!)
In the Marchant report there are 54 firms listed as manufacturing
agricultural machinery; according to the Kenny report (see 23/9/75)
eight firms account for 80% of the miniscule national production of
this potentially important commodity. So there should be an
appreciably market among small firms, unable to employ full-time
professional designers, for a competent service at the right price.
The Marchant proposition, basically, is that the engineering
industry ought to be prepared to underwrite the establishment of a
design unit at Kilkenny, on the services of which it could
subsequently draw, at a cost kept down by the build-up of continuity
of experience which one gets in a viable organisation.
Firms who feel the need for an industrial design service could
usefully explore what Kilkenny has to offer by putting to them a
specific design problem.
December 30 1975
On September 23 I received a report by James Kenny published by
the Science Policy Research Unit in UCD on the agricultural
engineering industry. This report showed up a rather abysmal
situation, with a ten to one imbalance as regards imports and exports.
Possibly in response to this, the IEI has arranged a two-day
seminar on February 3-4 on this topic.....
The market for this should include trade unionists and
managements of engineering manufacturing firms which are faced with
declining markets and redundancies (eg the vehicle assembly business),
as I suggested on September 23. The existing agricultural engineering
industry, which has been allowed to decline to a level barely above
the threshold of viability, can hardly be expected to recover without
an infusion of some new thinking and talent.
There is no evidence from the IEI programme of any input from the
Kenny Report. There are many speakers to the main papers: four per
paper; is this not too much?..... The main speakers are Dr Tom Walsh
(Director, AFT), MC heehy (Irish Sugar Co) and Ir(16) F Coolman
(Director of the Dutch Institute of Mechanisation)...... The closest
to a farmers' spokesman, on the respondents' panel, is Mr A O'Grady of
Mitchelstown Creameries.
February 10 1976
....At the Agricultural Engineering seminar last week (organised
by the IEI in association with the Department of Agriculture)...I
formed the impression that there was unresolved conflict between
individual and national objectives. Despite this, the elements of an
integrated system within Ireland were discernible, requiring State
initiatives to draw them together.
Let me explain what I mean. At present, whether in agricultural
engineering or food technology.....there are two key elements in the
system (a) the suppliers of equipment (b) the users. In both cases,
the users of equipment, on balance, prefer to deal with the world
market, excercising their judgment in the matter of choice of
supplier.
The result is a wide variation in types of equipment, and
problems in maintenance, spares, training etc. The alternative would
be for an association of users to organise consciously to influence
the design of appropriate standardised equipment, produced by the
agricultural engineering industry in Ireland, who theoretically could
be organised as a suppliers consortium, financing developments in the
universities, colleges and research institutes, and ultimately
breaking into the export market.
A conscious, organised, technically competent group of equipment
users could feel its way towards an optimal mix of home-produced and
imported equipment. An obvious sector to specialise in is
grass-harvesting, in terms of a total silage or dried-grass system.
There is, perhaps, scope for the development of clever grass-drying
systems without extravagant energy inputs, as an alternative to
accepting the comparatively heavy losses which accompany silage.
The key equipment users are the contractors and the co-op
machinery services. This is where the qualified agricultural
engineers ought to be concentrating; a pattern seems to be emerging
of technicians turned out by Clash (this Tralee VEC College is rapidly
upgrading to Regional College status) going into this work, but not so
much the graduates. There is a clear role here for the co-op
machinery services: to support a development-minded management,
trained to graduate-level technology, capable of understanding the
principles and specifying innovations, rather than a routine
management that takes care of technicians trained to operate existing
equipment.
With what body of engineers concerned with design and
modification ought our hypothetical 'users group' to be dealing? The
clear front-runners at the moment are the Sugar Co and Bord na Mona.
The former has a substantial export market with its Armer
beet-harvester, while the latter is a world-leader in the type of
soft-ground heavy equipment necessary in peat exploitation. To date
both have kept clear of the equipment market outside their own
sectors; the private sector, however, with names like Peirce of
Wexford and Keenan of Bagenalstown springing to mind, clearly lacks
the resources to stage an innovative come-back, and is likely to
remain in this condition unless it gets State support with development
work.
James Kenney, in his report published by the UCD Science Policy
Research Unit in March 1975, made a strong case for strengthening the
State sector, building on existing reserves of skilled manpower in the
Sugar Co and Bord na Mona, in a manner such as to help the private
sector rather than to displace it.
Given that the technological know-how and initiatives are
concentrated in the State sector, it is possible to visualise the
private sector getting in on both sub-contracting and marketing.
There is no need for the private sector to worry about an expanding
State sector; we are far from 'creeping socialism' and nearer to a
situation of State-supported R&D in the interests of the private
sector.
There is a long tradition in Britain of this, for example in
relation to the aircraft industry. Insofar as we have adopted the
principle in Ireland, via Bord na Mona and the Sugar Co, we can claim
that our State-supported R and D has been more socially useful.
To summarise: as regards agricultural equipment, the elements of
the system are mostly there.. We have the UCD agricultural
engineering department (which incidentally has soldiered on without a
professor for more than ten years!), the machinery evaluation centre
at Oakpark (Brendan Cunney), the existing State firms with a
developmental tradition; the missing link is an organisation of those
equipment users who are prepared to pool their experience, to specify
their needs and exercise decisive influence over producers of
equipment in Ireland, re-establishing a healthy home market.
On the food technology side, the prime centres of graduate
training and innovation are the UCC department of dairy and food
science, and AFT (Moorepark). The UCC graduates are all in the food
processing industry, occupying key positions. The demand for
innovations is beginning to emerge, and the lack of a
production-orientated centre for technological innovation beginning to
be felt. The industry is at the mercy of equipment-suppliers abroad,
and innovations researched and developed at Moorepark are being taken
u by foreign firms.
Thus, between the Sugar Co, the creameries and the milk
processors there ought to be scope for a national food processing
equipment industry, the key technologies being stainless steel
fabrication, refrigeration, process control instrumentation,
laboratory instrumentation etc.
This field was rather out of place in an agricultural engineering
seminar; it deserves a conference in its own right, with the
initiative in the hands of the equipment users, and a presence of
actual or potential suppliers. Perhaps this will follow.
February 24 1976
I am prompted....to remark on the rigidity of the thinking of the
Post Office as regards the provision of services in remote areas.
They think in terms of an urban-standard telephone service, requiring
a microwave link, costing perhaps £10,000. What is wrong, in
the case of the Black Valley problem, with the concept of a radio link
for emergency use only, with a continuously sensitive listening unit
in Killarney Post Office? A daily checking routine, whereby the
transmitter in the Black Valley was activated at random times by its
custodian, would ensure that the link was kept alive. Two or three
key people in the Black Valley could be trained in the use of the
system, which need be no more sophisticated than that in use among
fishing boats.
Systems like this are the norm in the Australian outback. The
total hardware cost should be of the order of a few hundred pounds at
most. This system should be applicable in many other remote areas,
including islands.
The same principle has held up for decades the provision of piped
water in remote communities. Why insist on urban standards, which lay
down that you must wash and flush your lavatory with drinking water?
As I have mentioned before, 19th century technology, as applied in the
Ascendancy big-houses, provided piped unfiltered water from the river
by means of a hydraulic ram. People knew better than to drink it. A
bucket of well-water, drawn at infrequent intervals, provided the
necessary dilution for the whiskey.
March 16 1976
It is probable that if Gibbon had gone in for the technological
history of the Roman Empire, rather than the political and social, he
would have noted the progress or regression of the status of the
engineer as a measure of imperial growth or decay.
The situation in Britain today as regards the engineering
profession is little short of disastrous. On January 11 I noted an
article by Peter Paterson in the Sunday Times which bewailed the
fragmentation of the 300,000-strong corps of professional engineers,
who between them support no less than sixty professional specialist
Institutes. The fifteen largest of these form a Council of
Engineering Institutions, of which the threatened split was the
stimulus for the article. This is taking place despite the best
efforts of the Duke of Edinburgh in his 'Prince Albert' role.
The issue is related to a unifying electoral reform plan. The
political details are outside the scope of this column, but the
situation of which it is a symptom is clear: engineers in Britain are
at the bottom of the league as regards status.
The type of status conferred by Royal patronage will not help
them. What they need is the type of status, based on recognised
competence, that gets their French and German counterparts from the
Ecole Polytechnique and the Technische Hochschule into the leading
positions in industry on the continent. In Britain the key positions
are taken up by 'gentlemen-amateurs' from the 'public-school' network.
The social structure in Britain is such that it is rare for this to be
challenged by the engineering profession within the management
structure.
In some cases where engineers have got to the top, as for example
in the Rolls-Royce debacle, they get blamed for having a narrow
concern with technical excellence, to the exclusion of social or
economic considerations.
The British educational system (which we tend to ape) has
traditionally steered the best brains towards scientific excellence
via Oxbridge, with the result that while there may be more Nobel
Prizes per head of population, the technological follow-up takes place
abroad and the British have to buy back the fruits of their own
discoveries. Meanwhile, the splintered engineering profession muddles
on with its 'standard practice' approach, or else allows itself to be
drawn into sterile prestige projects via the (now moribund) military
aviation industry.
I am drawn into this harangue by the January issue of the
Chemical Engineer (a progressive professional sector, with healthy
influences from the US) which has a Jeremiad by IA Glover, who is a
sociologist working at Heriot-Watt Univerity (Edinburgh).
I quote: '...lack of collective unity....due in part
to....practitioners.....employed as technician-managers rather than as
generalists.....misleadingly defining practical skills as
specialist....an over-supply of diffident practitioners.....elites of
gentlemanly amateurs and overpromoted book-keepers....in stark
contrast to the situation in Europe...'
Elsewhere in the same issue is a quote from Lord Bowden,
Princopal of the University of Manchester Institute of Science and
Technology (UMIST): '...we used to have the biggest undergraduate
school of chemical engineering in Europe. For a decade or more it
recruited 90 Englishmen and half a dozen foreigners each year. This
year it admitted 23 English and 25 foreign students...... Englishmen
no longer want to study any discipline which would fit them for a
career in productive industry...'
I am indebted to Derry Kelleher, who used to be secretary to the
Irish Branch of the Institute of Chemical Engineers, for sending me
these extracts.
I must say that the Irish engineering scene, though numerically
weaker, seems to me to be basically healthier. There do not seem to
be the same barriers to entry into the top management that exist in
Britain, except perhaps in the older Anglo-Irish firms. But the
situation is far from healthy as regards interaction between science
and engineering. My recipe for the future career-profile is to start
off as a scientist, become an engineer and then end up managing what
you have developed; this cycle to be repeated two or three times in a
career. Is this visionary?
March 23 1976
As a follow-up to last week's 'cri de coeur' on the status of the
engineering profession in the UK, I note that the working party of the
Council of Engineering Institutions.....has recommended.....that
professional engineers should join Trade Unions. This is a new
departure, in that hitherto the Engineering Institutions have been
trying to combine the functions of Trade Union, Learned Society and
Professional Institution in one system.
However well the latter two mix, the first is clearly an
outsider. Most engineers being employees, a Trade Union is closely
relevant to their interests. Many of their employers, if also
engineers, could also be members of the Institution, so clearly the
Trade Union function is pre-empted. The fact that this has only now
been recognised in the UK is a contributory factor to the engineers'
low status.
The January/February issue of the ASTMS Journal reports the above
intelligence with visible relish. The ASTMS in Ireland organises the
majority of scientists and technologists working in the State sector.
The AEUW-TASS is strong among engineering technicians.
September 9 1976
I have previously drawn attention to the potential for an
agricultural engineering industry in Ireland...... Recently the IEI
published the summarised conclusions of the February conference;
there was a reception at Clyde Road to mark the occasion, to which the
Minister for Agriculture was invited, but which was attended by a
substitute, in the form of Mr Oliver Flanagan TD. This event received
no press coverage of any significance.
The IEI report contrasted the positive attitude of the industry
in the USA, Holland, Britain and New Zealand to the employment of
agricultural engineers with the fact that most of the UCD output of
these were working outside their specialities or else abroad. It
called for the employment of agricultural engineers in the advisory
services, in food processing, in research, and, especially, in a
renascent agricultural engineering industry.....
The response of the Minister to this report, as evidenced by the
departmental script read by Deputy Flanagan, was anything but
encouraging. There appears to be little appreciation in the
Department of the potential role of engineers in the development and
adaptation of equipment to a state where it is suited to Irish needs,
despite the experience in this field of the Sugar Co and Bord na Mona.
More agressive engineer-entrepreneurs are needed, if this road-block
is to be breached. A viable system might have inventive graduate
engineers, with adequate technician support, working for the co-ops.
AFT Oakpark and UCD would then be in a position to respond with
enthusiasm with solutions to problems defined with precision by
trained specialists in the front line of the action.
The output from the UCD/Oakpark system would be working
prototypes, or prototype 'mods' to existing systems, developed to
local consumer specifications, suitable for licencing out to local
manufacturers. This was the conception behind the IEI conference
which prompted the publication of the report. Regrettably there are
no signs of support for the concept either from the Department or from
the equipment purchasers.....who prefer to shop in the world market,
where they have variety of choice but no control over the
specifications.....
October 12 1976
(Regarding the IEI conference in Sligo) I feel I should remark
that I see danger signals in the North-west in the general area of
science-technology linkages; for example the North Western Scientific
Council was not much in evidence round the fringes of the IEI
conference, despite the attempt made....to build the bridge.
Conversely, when the NWSC ran a seminar in Sligo on finite-element
methods, which was attended by about 30 participants from all over
Ireland, including from the North, there was little or no interest
shown by local IEI members.
Hopefully when the Operations Research Society meets in Sligo on
November 4-6 there will be some local support from both scientist and
engineers, as this discipline was invented specifically to help
quantify the steps involved in the introduction of new technologies,
fresh from the scientific boffins, into an engineering (or
'operational') environment....

I must now fill in on the annual conference of the IEI which took
place on September 30-October 1 at Rosses Point. In last week's
passing reference I touched on the problem of science-engineering
interaction..... This problem underlay the conference itself, which
was on the theme 'The Engineer in a Developing European Society'.
The IEI executive....clearly is aware of the implications of the
increasing rapidity of technological change for a profession which, in
Ireland, is dominated by local authority engineers whose methods of
work are traditional. The roots of technological change are in
science. So the IEI invited two heavyweight spokesmen from the
scientific community to come and rock the boat.
The first was Manfredo Macioti, who serves the EEC in the
Directorate for Research, Science and Education. The second was Colm
O h-Eocha, now President of UCG, who is completing his lengthy spell
of office as Chairman of the National Science Council.
Macioti took a world-view of the innovation process, producing
figures showing trends in patents per annum, illustrating the decline
of the US, the stability of the EEC and the buoyancy of Japan and the
USSR. This related to the period 1965-72.
The crude numbers however are misleading; if you split the
figures into 'high, 'medium' and 'low' technologies, the US leads in
medium and Japan in high, while the EEC is more interested in low
technologies.
(Typical 'high' technologies are electronics, applied
microbiology, nuclear engineering, instruments; soap, glass,
metallurgy and food count as 'medium', while low technology areas are
dyes, paints, building and construction etc. These divisions are
somewhat arbitrary, but they reflect factors like how long the
technology has been around, the level of qualification of those who
control the technical decisions, and other such factors.)
The worrying fact for the EEC is that as well as being dependent
on imported fuel and raw materials, it is in a weak position as
regards balancing the trade in technology. Many of the third-world
countries are themselves becoming strong in the low-to-medium
technologies, in which the EEC is pre-eminent.
The way in which EEC technology is reacting to this problem is
not so much to force-feed the high-technology sector as to transfer
attention from 'products' to 'systems' and 'services'. Thus the way
forward for the engineering profession is towards the development and
maintenance of total systems, which may be quite complex, of which the
components are medium-to-low technology.
The closest traditional engineering discipline to this concept is
that of the production engineers. Justin Wallace's 1973 paper on the
technological needs of the Irish engineering industry, with its
emphasis on the need to recruit and train graduate engineers for jobs
in manufacturing, needs resurrection....
Macioti spent some time on scenarios for the year 2000...... One
proposition is the compulsorily renewable professional engineering
qualification; in other words your degree lapses after 7 years unless
you go back to college to update it......
I come now to O h-Eocha, who gave as an example of the trade-off
between raw material and technology the replacement of 175,000 tonnes
of copper by a communications satellite weighing less than a tonne.
In Ireland the industrial pull for new technology is weak, there being
too few qualified technologists in industry; consequently the State
must 'push', and this the NSC has been doing with its
university-industry schemes.
Professor O h-Eocha also touched upon a basic weakness of the
Brussels connection: '...we must often rely on the jack-of-all-trades
to service important committees where larger countries assign
well-briefed experts....' There are two solutions to this problem:
one is to pull out and establish an independent national economy like
Norway, replacing membership of the EEC by a trade agreement with it.
The other is to break the stranglehold of the professional civil
servants on the EEC linkages, and to put in well-briefed people who
know the problems and the significance of the matters discussed.
There are some areas where this is beginning to happen, but others
where important techno-economic decisions are made without any
knowledgeable contribution by the Irish contingent.
If we adopt the second solution, is is likely that the EEC
committees will dull and break the spirit of our most creative people,
and the pace of creative innovation at home will be reduced to a
negligible level. So we are in a national dilemma, brought upon
ourselves by the national capitulation which took place in the 1972
Referendum. Those of us who constituted the 17% residuum of
unrepentantly national-minded people who voted 'no' to the EEC can
say, with sorrow, we told you so...... People are realising the
fragility of our claim to be a nation at a comparable level of
development to France or Germany.....the analogy with the 1800 Act of
Union is becoming increasingly evident.

On October 6-7 a seminar took place in TCD under the title
'Towards High Quality Welding'; this was organised by the TCD
Graduate School of Engineering Studies, the College of Technology
(Bolton St) and the Irish Institution of Ingineering Inspection.
Topics included: prominent weld failures, welded joints in
structures, the Nodus Joint System in space frames, the role of the
resident engineer, etc. The final paper on 'the Conflicting
Requirements of Quality and Productivity in Welding' was by Professor
R L Apps of the Cranfield Institute of Technology.
The 43 participants were mostly from engineering consultancy and
manufacturing firms.
This seminar represented the fruits of extended efforts by Ken
Eng, lecturer in welding at Bolton St, to establish that quality
welding knowhow is a reality in Ireland and that it is no longer
necessary to import it....
I listened to NT Burgess of the British Steel Corporation on
'prominent failures' and picked up....that 80% of failures are due to
management and not to the quality of the actual weld. In the case of
the Flixborough disaster, no engineer was responsible and no drawings
existed of the replacement piping. Pressure vessel failures can be
due to poor temperature control at the heat-treatment stage.
Scale-ups which took place in the sixties have given rise to
unexpected elements becoming critical, like lifting lugs.
Repairs should not be regarded as natural; if you spend twice
the money on quality engineering the cost of failures is reduced by a
much greater amount. One boiler-tube leak is equivalent to 10 days
down-time. The statistical basis of sample inspection procedures is
theoretically weak. Inspectors are often sopoorly qualified that they
are not respected by the welders whose work they examine..... good
material here for applications research.
...a paper by Dr NG Bunni, of TJ O'Connor Associates...
(represents the Association of Consulting Engineers of
Ireland at the Euro-Arab Export Group..) (dealt with) the Nodus Joint
System which is a means of pre-fabricating wide-span roofs with
standard components. The basic unit is a length of tube with welded
end-pieces. The technique for doing this with precision and without
flaw was the subject of the talk, which was supplemented by Ken Eng
himself, who had a hand in the job. When the roof was assembled the
calculated camber (4 inches in 70 feet) was achieved exactly. Welds
were tested destructively by cutting and examining a 2% sample. For
technical reasons non-destructive testing would not have worked (to
find out why is another research area for the frontiersman).
The indications of this seminar are that the increasing
co-operation among the centre-city colleges is paying off, and
strengthening the links between science, technology and industry....

The re-development of a viable agricultural engineering industry
in Ireland will not take place overnight. It must be rooted in
effective technology and directed at the solution of recognised
problems.
The machinery division of AFT at Oakpark has developed an
automatic milk cluster remover, which senses when milk flow finishes,
using a vacuum signal. This device is produced by Mullinahone Co-op,
which has already sold 500 units in Ireland and exported a further
1000 to Europe and the US.
According to Mr Brendan Cunney of Oakpark, the main bottleneck is
market intelligence; to have someone in the problem area who can
visualise an engineering solution to a problem quickly and
effectively, without being hidebound by the traditional slow
procedures of agricultural experimentation. Agricultural statistics
are only one of the elements necessary for market assessment.
Although the size of the typical agricultural engineering firm is
small, and qualified expertise still rare, this is being remedied and
good agricultural engineering technicians are now increasingly
available. It is the small firm, having good technical expertise,
close to the farmers' problems, which is the most likely to deliver.
The Mullinahone enterprise supports this contention.
The annual conference on agricultural development organised by
AFT (November 25) covers the usual areas of interest..... The fact
that there is no slot on the agenda for a survey of the equipment
scene suggests either that the industry has no problem or has not
recognised that it has. It is up to the suppliers of Irish-made
equipment to persuade the industry that the present import-dominated
market is not adapted to the needs as well as local enterprise would
be, at least in certain specialist sectors. When the engineering
industry breaks into the agenda of this particular AFT annual event,
it can be said to have 'arrived'.
December 21 1976
I listened to Dr Percy McCormack of the NSC speaking at a meeting
of the Royal Aeronautical Society on December 14 in Clyde Road, by
courtesy of the IEI.
Dr McCormack, who spoke from a position of considerable direct
experience, suggested that there were some 10-12 firms in Ireland
which should be in a position, individually or in consortium, to get
sub-contracts from the European aerospace industry. European Space
Agency contracts, which were often of a manageable small size, would
be a good way into this league.
He suggested that the Aer Lingus technical division was well
placed to play a leading role in getting sub-contracts, mainly in the
equipment and systems areas, and in airframe sub-assemblies, rather
than in engines.
A pre-requisite for this, however, was the cultivation of R and D
linkages with the universities and colleges of technology, where there
were some significant (though isolated) linkages into world
high-technology research.
Indications from the subsequent discussions, however, were that
this (to my mind good) advice went largely unheeded, the Aer Lingus
technical development people preferring to rely on their equipment
suppliers as their main source of technological information.
This, I would have thought, was more typical of the small family
firm than of the exporter of high-technology expertise which Aer
Lingus now is, to the extent that they are helping to set up airlines
and aircraft maintenance systems in some 20 developing countries.
Ultimately, any new electronic or other system, of which the
prototype had been developed in Ireland as a result of an Aer Lingus
university-industry project, would have to find its way into
acceptance by Boeing, BAC or whatever major aircraft manufacturer was
involved. This, however, does not preclude Aer Lingus from taking an
open-minded and innovative attitude in the early stages. Whatever
chance a university electronics group had of selling to Boeing an idea
that had been developed in the light of the experience of a Boeing
purchaser, the chance of such a group succeeding with a direct
approach to Boeing is negligible.
Dr McCormack mentioned Shorts in Belfast as a firm worthy of
cultivation in this respect; this firm is of course the only centre
of direct experience in airframe and aerospace systems in Ireland; as
such it could play a key role in any Irish-based consortium bidding
for European aerospace sub-contracts.
NOTES
1. Val Rossiter's interests developed towards infra-red spectroscopy.
He invented a system for doing IR analysis on gas chromatograph peaks,
and went on to found a firm, Accuspec ltd, to produce it for the
market. At the time of writing, this firm is expanding into the US.
2. See Chapter 5.1 on 2/4/70.
3. Professor Calderwood was then at Salford University.. He is
currently at University College Galway, having left Salford as a
result of the Thatcher cuts.
4. For the Naas Research Park background see Chapter 1.2 (Structures
and Institutions) on this date.
5. Dr Chambers went in some detail into the electron beam optics, and
the nature of the secondary emission processes that give rise to the
various types of image. The principal use envisaged in the IIRS was
the examination of fractured metal surfaces, with a view to
establishing the fracture mechanism. There was also potential for use
with solid-state electronic devices.
5a. At that time the lady engineer was somewhat rare. The present
trend of women into engineering is welcome and should have a
humanising effect on the profession. For 'him' read 'him or her' etc.
6. In retrospect it has emerged that from the College's point of view
it was under-priced, the administrative overhead necessary having been
underestimated. There was no incentive to repeat the procedure in
this manner. Custom-designed MSc programmes are still done, but at a
more realistic fee. The TCD/SPS link has continued, and Paul Wallace
spent some time as the TCD Professor of Mechanical Engineering; he
has now returned to SPS.
7. The development agency responsible for the Western areas where the
Irish language survives, precariously. It is now called Udaras na
Gaeltachta, and has an elective component.
8. The Electricity Supply Board took a dim view of this enterprise,
which put some hundreds of kilowatts of load at the end of a fragile
rural distribution network. It would have made more sense to have
located the enterprise near a reliable mini-hydro source, or in a
town. The main reason for the location was that Jim Gilson liked the
environment, and the supplier of equipment was an Achill man, who had
emigrated to the US some decades previously. Also the Gaeltarra
financial incentives were generous.
9. This was occupied at the time by the present writer. In
retrospect it can be said that the analysis of the subsequent failure
of this enterprise would provide many insights into the weakness of
the Irish techno-economic infrastructure, as seen by the small
high-technology firm. One factor was the dubious quality of the
second-hand X-ray equipment, on which a key step in the process
depended (namely the alignment of the crystals); this was not
identified prior to purchase. A complication was the Achill link of
the equipment vendor; he had the status of a local hero.
10. Qeleq over-reached itself in its marketing and foundered on
cash-flow problems. A major customer took over the rights and the
systems sold were maintained. Prior to collapse, they were beginning
to go into the 'dedicated micro' business; there were signs that this
would in the end open up new markets untapped by the minicomputers.
They had developed what would now be recognised as an early version of
the 'visicalc' system, or at least a system with the same philosophy.
This they subsequently tried to market on a bureau basis. They had
also developed an analogue approach to the production scheduling
problem, and were beginning to digitise their approach to the solution
of the linear programming problem, while keeping what the chairman of
the company, William Marshall, called 'analogue feel', which users of
the original feed-mix computer liked. Qeleq deserved to survive; it
appears to have suffered from a fate common to many pioneers, namely,
being just slightly too early, with the imagination leaping ahead of
the technical feasibility.
11. The national export trade promotion agency.
12. Thanks to new digital technology and a radical change in State
policies, we now expect to be in that position by 1990 or before.
12a. The National Council for Educational Awards. Prior to its
establishment in or about 1970 all technician-grade qualifications
were London-based.
13. The co-ordinates of bubble-chamber pictures of high-energy
nuclear interactions were recorded in the 50s as digitised input to
first-generation computers, in Stanford, Berkeley and elsewhere in the
US, by an essentially similar technique.
14. For more on this anomaly see Chapter 3.5 (Biotechnology) on
21/4/71.
15. Nothing came of this. It remains an object-lesson to illustrate
the priority of need.
16. The Dutch use the style 'Ir' to denote 'engineer' as 'Dr' is used
to denote 'doctor', reflecting a positive cultural attitude to their
status.
