Another thickness gauge Those who have abandoned the ageold method of cutting a hole and using a ruler have a wide variety of ultrasonic thickness gauges to choose from. Baugh and Weedon have recently added a small portable gauge to the list (Fig.3). The PA 1040 measures 300 x 250 x 100 mm and weighs about 3.5 kg. It employs the pulse-echo principle. Two piezoelectric transducers are used, one for steel up to 255 mm thick and the other for thin material down to 0.25 mm.

K. J. Law Associates of Detroit have recently introduced an eddy-current thickness gauge for non-conductive coatings on conductive substrates. The instrument, the Magemike measures coatings up to 40 mm thick and Law claim an accuracy to 1.0% or to 0.025 mm which they say can be further improved to 0.5% or 0.013
The instrument incorporates automatic gain control. The measurement is given on a digital display with a facility for keeping the figure as the probe is removed from the wall (eg for hot materials). The PA 1040 is powered either from ac mains or from batteries. It gives measurements in either imperial or metric units. Baugh & Weedon Ltd, Blackfriars Street, Hereford, Herts, UK

FROM THE W O R L D "lime for a change in Argentina by J. Hislop, UN project director
Since there seems to be some confusion over the aims and objectives of this project and its relation to existing Argentine ndt institutions, I feel a few words of explanation and an early progress report would be in order. The Centro Argentino de Ensayos no Destructivos de Materiales (CAEND) or Argentine NDT Society, is a technical association originally formed to act as a forum for discussion and has subsequently mounted courses of lectures in Buenos Aires for ndt technicians. Up to date these have been strictly limited by the resources available to the Society which has no permanent premises or full time secretariat, and does not possess its own lecture rooms or demonstration equipment, and does not effectively operate outside the area of Greater Buenos Aires.
but the UNDP project will help speed up the process. For essentially practical reasons, the base of the Institute is the existing ndt group within the technological department of the CNEA. There already exists within this department much technical expertise in both general and nuclear metallurgy and engineering. All the facilities of the metallurgical laboratories will be available to the new Institute along with the library and information system at the Constituyentes site, as well as the services of the Isotope Production Division at Ezeiza (Neuqu~n), and the Bariloche Physical Laboratories. Equipment available in these establishments includes the items listed here as well as a full range of standard laboratory equipment. 25 MeV linear accelerator, electron microscope (Philips EM 300), electron micro-probe analyser (CAMECA MS46), laser microprobe analyser (Zeiss LMA 1), x-ray diffraction equipment, x-ray spectrometer, 1 024 channel gammaray analyser (nuclear data S-2200), atomic absorption spectro-photometer, tensile and fatigue testing machines, ultra-high vacuum equipment and furnaces, electron beam furnace, nuclear reactors: Argonaut (150 kW) and MTR (8 mW) having irradiation facilities with a capacity of 106 Ce Cobalt 60.
The new National Institute (INEND) is being created, with the help of United Nations Development Programme (UNDP) funds, and a great deal of enthusiasm by Juan B~iez, its Argentine Director, and his existing ndt group in the National Atomic Energy Commission (CNEA). Its function will be to provide facilities for research and development, guidance and advice, technical meetings in Buenos Aires and other industrial centres, training in depth and at all manageAt a meeting of the Sociedad Argentina ment levels, and the production of de Metales, held within a few days specifications and standards in conjunction with CAEND, the Argentine of the project director's arrival in Buenos Aireas, many contributions Institute for Quality Control (IACC), to both formal symposia and discusthe Argentine Standards Institute sion periods laid emphasis on the (IRAM) and many othel" professional pressing need for national standards bodies. The long-term objective of and ndt specifications which would existing institutions has always been take into account local conditions to provide these facilities and services,

and general levels of experience in industry and commerce. The superficial application of standard specifications originating from the United States and Europe have led to many problems, since they have usually been drafted originally with the background of a highly developed industrial nation in mind. One of the urgent jobs of the Institute will be to provide experienced personnel and information to help in the preparation of suitable national documents. To achieve these aims and to provide the direct technical assistance needed by Argentine industry, it will be necessary to recruit local personnel with sound scientific backgrounds and arrange training and education programmes for them in Europe and the USA. Experts from abroad will be recruited for short-term attachments to help on specific problems and to take part in the more general training programmes to be held in Argentina. Laboratory and office space, local supplies, and auxiliary services will be provided by the Argentine Government and instruments will be imported from abroad to equip the facilities and back up all this local effort. Permanent training facilities with teaching accommodation, lecture rooms and demonstration equipment, will be made available to allow the organisation of courses for Argentine personnel so that the knowledge and experience already existing, with that collected from overseas sources can be passed on by the Institute's staff. In addition a mobile laboratory with facilities for x-ray, ultrasonic, magnetic particle, penetrant and eddy current inspection will be provided for training, publicity and demonstration work, especially away from the Buenos Aires area. If any of the readers of this journal feel that they could assist in providing training facilities or would be prepared to come to Argentina as a visiting expert, please contact me with all relevant details of their organisation and experience. Perhaps three years will hardly be enough time to set all this in motion and help in its formative growth. However, if the enthusiasm and vision of the Argentine personnel involved is any guide, the project will be in good hands for many years after the formal participation of the UNDP has come to an end.
