biggest cryogenic vessels made by W P Butterfield (Engineers) Ltd, just after leaving the company's works at Shipley, Yorkshire en route for the ICI Dyestuffs Division at Stevenston, Ayrshire. The vessels will store liquid nitrogen in quantity as part of a nylon intermediates plant. They were ordered from Butterfields (a member of the W P Butter'field Group) by Petrocarbon Developments Ltd, of Manchester, who are the main contractors to ICI for the nitrogen plant, of which the vessels form the main storage units. Each vessel weighs 30 tons when empty, will contain 10,000 Imperial gallons of liquid nitrogen and measures 23 ft× 15 ft I} inches ~<14 ft 7~ inches. The inner containers are of 304 stainless steel, the outer jackets being of carbon steel. The support arrangements of the i~mer containers were specifically designed to counteract stresses caused by thermal contraction and expansion between the inner and outer units--the space between the two being fully evacuated and filled with a highly efficient powder insulant. Instrumentation is in a lockable cabinet built on to each vessel. The vessels are designed and constructed in accordance with the American Society of Mechanical Engineers (ASME)Code, 1965 Section VIII for a working pressure of 105 lb per square inch. Veeco annual report The annual report to shareholders of Veeco Instruments Inc, for the fiscal year 1st October 1965 to 30th September 1966, has been issued. The annual shareholders' meeting was held on 31st January 1967 in Garden City, Long Island, New York. During this year, the Company acquired Lambda Electronics Corporation and have moved all product design and manufacturing activities concerning electronic vacuum equipment to Lambda's nearby plant in Melville, Long Island. Veeco's plant at Plainview will concentrate its efforts on more basic aspects of high vacuum technology such as ion physics, electron optics, pumping techniques and mass spectrometry. The decision of the Board of Directors to omit payment of a dividend for this year, arose mainly from the expense of this acquisition. Throughout this period two new vacuum products were introduced: the CS-775 Gauge Calibration System for determining the accuracy of high vacuum measuring devices and the GA-4R Residual Gas Analyzer, a simplified and less expensive modification of the existing GA-4 instrument. Tenney Engineering profits A net profit, after taxation, of $75,887 or 13 cents per share for 1966 was reported by Tenney Engineering lnc, compared with $12,259, or 2 cents, in 1963. A considerable reduction in the net sales was attributed to the fact that the 1965 sales figure included the sales made by the company's plate fin coil and unit coole= facilities in Wilmington, North Carolina, which were sold in September 1965.

Conferences, Exhibitions and Courses Cryogenic Engineering A one-week course in cryogenic engineering will be held at the University of Alabama, Huntsville in June 1967, dealing with processes and techniques at temperatures below --150°C. Each day will involve six hours lecture time and two hours discussion time. Lecture topics include: high vacuum heat transfer principles; space applications and simulation; thermodynamic principles and cryogenic fluid properties and instrumentation at cryogenic temperatures. Further information on the course is available from D J Kieselbach, University of Alabama, Huntsville Campus, PO Box 1247, Huntsville, Alabama 35804, USA. Spark source mass spectrometry course A two day study course of interest to researchers and scientist concerned in trace analysis is to be held at the Fnlmer Research Institute, Stoke Poges, Buckinghamshire, on 16th and 17th May 1967. The course is sponsored by AEI and the Fulmer Research Institute and will include an introduction to spark source mass spectromelry, demonstrations using the Fulmer Research Institute's AEI MS702 double focusing mass spectrometer, and lectures by leading specialists in the field. It is believed that the Fulmer Research Institute is the first research organisation to offer a commercial analysis service to industrial and academic researchers and this course is designed to show the latest techniques for analysing and measuring trace elements in natural products, dental samples, semiconductor materials and metals, among other uses.
Stand 103 at the Radio and Electronic Component Manufacturers' Federation exhibition, at Olympia on 23rd--26th May 1967, will contain a number of recent developments from G V Planer Ltd of Sunbury-on-Thames, Middlesex. The Eyelet thermocompression bonder is a novel approach to the production of vacuum tight metal-to-metal bonds. Precise control of the approach rate and dwell time of the tool coupled with a special design which induces lateral flow of metal during bonding, extends the range of possible joints to aluminium-to-aluminium welds. Facilities for atmosphere control and easy observation of the bonding operation are also incorporated. The company's hot gas soldering unit is a modified form of the original hot gas MicroBonder, aimed at simplicity and economy of operation. A new vacuum control head and vacuum meter switch, provides a means for controlling vacuum coating systems over the range of from I torr to 5 - 10:3 torr and 3 ~: 10 :' tort to 5 ~ 1 0 " torr. The operation relies on the monitoring of output currents from the Pirani and Penning gauges in the vacuum system which are displayed on meters with two adjustable control limits for each range. The latter provide threshold facilities, eg for the operation of regulating needle or baffle valves in the vacuum plant. The system can also be used to provide switching from the rotary to the diffusion pump in vacuum coating plants or to initiate a vacuum coating cycle at pre-set pressures. A combined electron beam conversion kit, fitting most sizes of existing vacuum evaporators, is shown in use on a Planer special purpose 19 inch vacuum coater. The water-cooled electron beam source can be focused actually during use in the vacuum chamber, and a spot size of less
