Vacuum news
New vacuum metallurgical service company Rudolf Wolff & Co the London metal brokers and merchants have formed a new company-Wolff Brazing Limited, 251A Main Street, Bellshill, Lanarkshire, Scotland, which specializes in sub-contract high vacuum metallurgical processes for precision brazing and heat treatment. The company has installed the Scot-Vac FV 32R (Mo) high vacuum furnace to undertake this work. The furnace which incorporates an adjustable gas-quenching system is suitable for hardening, tempering and annealing of a very wide range of steels and for the sintering and brazing of the more complex aerospace alloys containing reactive elements such as titanium, aluminium and cobalt.
A selection Of components after vacuum treatment at Wolff'Brazing Ltd. The company offer the following specialist services: hardening and tempering of high-speed steel tools, die blocks, punch tools, etc; bright annealing of steels, stainless steel, titanium and nickel alloys; sintering of compacts such as titanium, copper, iron, tantalum, nickel, stainless steel, etc. ; brazing of precision parts made from titanium, stainless steels, nimonie alloys and hastalloy; surface degassing of steels for the nuclear industry, titanium alloys and alloys and metals for thermionic valves. In addition the company run a development service for their customers for experimental work and employ a small vacuum furnace capable of handling work pieces 5 in. diameter x 6 in. long to a temperature up to 1600°C. in a vacuum of 5 x 10 -5 tort, for this purpose. Mr J A Brown, Managing Director, Wolff Brazing Limited, 215A Main Street, Bellshill, Lanarkshire,
Scotland. Veeeo sales and earnings Veeco Instruments of Plainview, New York, manufacturer of high vacuum systems and instruments, leak detection equipment, and "Lambda" power products, have reported their sales and earnings for the first quarter of fiscal 1971. For this period, sales were $5,026,067, net operating income was $205,939 and net operating income per share was 16c. For the first quarter of fiscal 1970, sales were $6,784,457, net operating income was $411,467 and net operating income per share was 32c.

Mr Frank Raible, President of Veeco Instruments Inc., cited the poor business conditions within the Electronics Industry during the quarter as a reason for the decrease in both sales and earnings.
Granville-Phillips acquires Kronos Inc Granville-Phillips Company, Boulder, Colorado, have acquired the entire common stock of Kronos Inc., Torrance, California, which will be operated independently as a wholly-owned subsidiary. Kronos are claimed to have introduced the world's first high quality digital thin film deposition control systems, providing improved quality and reduced costs for microelectronic circuits by automatically controlling certain variables in the production process. Optical, decorative, protective coating, and solid state component industries also employ this control equipment. Granville-Phillips previously owned a minority interest in Kronos. The complete acquisition of the Torrance firm is part of a programme intended to broaden the activities of Granville-Phillips into more industrially oriented markets, as well as to provide its existing customers with additional integrated components. Granville-Phillips manufactures vacuum instruments and systems and sells a complete line of such equipment which includes some 54 products. Dr Earl H Blevis will continue as the Chief Executive Officer of Kronos. He will be assisted by Cleve R Hildebrand, Vice President Engineering, and Dr Richard L Strayer, Vice President Finance. Granville-Phillips Co, 5675 East Arapahoe Avenue, Boulder, Colo 80303, US 4.

N e w literature Airco Temeseal Recent issues from Air Reductions Co lnc include: A brochure on electron beam evaporation covering applications, mechanical handling of source materials, effects of contaminants and pressure in the vacuum chamber, and effects of substrate texture, temperature and composition on deposition. A four-page data sheet describes the TP-10 planetary substrate holder which will accommodate 57 or 111 two-inch substrates in an 18 x 30 inch or a 24 × 30 inch bell jar respectively. The planetary movement is claimed to allow only a 2 to 5 per cent variance in uniformity of substrate coating. The effects of substrate temperature on film deposition are briefly described. Other data sheets describe the Series 2000, stainless steel angle valves with four types of actuator which may be interchanged without breaking the vacuum. This type of actuator is also applicable to the Series 6000 gate valves which also offer
high conductance and may be mounted in any position. Both types of valves are mass spectrometer leak tested to 5 x 10-1° standard co/second sensitivity, and seal against the atmosphere in either direction.

C onf erence and group activities Call for papers for the Fifth International Vacuum Congress and the 1971 International Conference on solid surfaces The Fifth International Vacuum Congress sponsored by the International Union for Vacuum Science, Technique and Applications will be held from October 1 l to 15, 1971, at the Sheraton-Boston Hotel, Boston, Massachusetts, USA. The objective of the Congress is to provide a forum for the discussion of new and significant work in vacuum science and technology, thin films and vacuum metallurgy. The International Conference on Solid Surfaces co-sponsored by the Surface Science Division of the American Vacuum Society, by the Fifth International Vacuum Congress, and by the International Union of Pure and Applied Physics (IUPAP) will be held in conjunction with the Congress. The aim of the conference is to provide a broad forum for the presentation of outstanding scientific work in areas of surface science which currently are active and progressing rapidly. The programme committee invite the submission of papers for these meetings. An informative abstract must be received by the programme chairman before May 19, 1971. This deadline has been set as close to the conference as is possible while still allowing time for writing and reviewing of the manuscript; the procedures are intended to permit rapid publication of the Proceedings. The abstracts will be reviewed and notification of the provisional acceptance or of the rejection of an abstract will be sent to the author within two weeks of the above date. Upon receipt of notification of acceptance of this abstract, the author must submit a manuscript of the paper to the Editors of the Conference Proceedings, to arrive before July 28, 1971. When such manuscript is received the abstract will be included in the final programme for presentation at the Congress. The manuscript should be in English, limited to 3000 words. Full details on the preparation of the abstracts can be obtained from the Programme Chairman, Dr J H Singleton, Westinghouse R&D Centre, Beulah Road, Pittsburgh, Pennsylvania 15235, USA.
