(the newton) which m some sectors may be less well known than the unit of force in the system of metric technical units (the kilogrammeforce). The new booklet outhnes the htstorical background to the international recognitmn of SI metric units, explains what they are, comments on the use of the newton as the unit of force, and indicates also how the units may best be introduced in industry. The more important British Standards which prowde further information on the use of SI units are hsted in an appendix. It is expected that there will be considerable demand for the new pubhcation m industry and in training departments, technical colleges and the hke. Pressure/vacuum pump design bulletin A new two-colour speclficahon bulletin especially designed for engineers revolved with pressure/vacuum pumps has been announced by Guide Industries Incorporated and is now being offered free of charge. This latest Guide Speclficahon Bulletin describes m detail eleven pressure/vacuum pumps available for immediate delivery. An easyto-read chart on the back of the bulletin gtves the user at a glance specifications on envelope size, motor type, capacity of vacuum and pressure, current at rated load, electrical connection, etc. The chart also permits a quick comparison of specifications between the various pressure/vacuum pumps available. Copies of the bulletin may be obtained free of charge by writing to Guide Industries Incorporated, 11855 Wicks Street, Sun Valley, California, USA. Roots-type compressor A thermo-compression Roots-type compressor, clmmed to be the biggest of its kind, has been designed and built by George Waller and Son Lzmited the Stroud, Gloucestershire, engineers., The machine, which is capable of operation under vacuum conditlons down to 28 inches of mercury has a displacement capacity of 13,400 ftS/mm at its operating speed of 900 rpm, and weighs about 4 tons The compressor forms an zmportant part of a new plant for the evaporatmn of mdk, gelatine, meat and vegetable extracts and other foodstuffs or chemicals.
ton Buildings, Chancery Lane, London w e 2 . It will be open, a d mission free, from 10 am (11 am on Monday) till 7 p m (1 p m on Saturday). The exhibition will show how the Library has to handle every week over 7000 new items (books, periodicals, pamphlets and patent specifications) in order to provide both readers in the Library and scientists and technologists at a distance with the various forms of reference ~ervice they require. Eurofinish/Vom'66 This metal-finishing exhibition, which is organized by the Society of Metal Finishing Techniques in collaboration with the Royal Netherlands Industries Fair, Wdl be held in Utrecht from 20 to 24 September 1966. It provides an opportunity for the metal industry to bring itself up-to-date in the speciahzed field of metal finishing processes, technical applications and equipment. The exhibits will coyer the entire field of metal finistung including vacuum deposition. All enquiries regarding the Exhibition should be addressed to Exhibition Consultants Limited, 11 Manchester Square, L o n d o n Wl.
Appointments General Electric appointments The Vacuum Products Operation of General Electric has expanded its customer service capability by appointing Frederick C Foshag manager of application engineering and William F Dolke as manager of customer service and product planning. Both are newly created positions.
Silver medal award for Mullard film The Mullard film, "Thin-film Microcircuits", was awarded a silver medal (lst prize) m zts category at the 10th International Festival of Scientific-Teaching Films, organized by the University of Padua in conjunction with the 1965 Venice Film Festival. "Thin-film Microcircuits" is a 16ram sound and colour film which deals with the manufacture of this new type of electronic component from design stage to the finished product. The film also describes typical applications including space vehicles, miniature computers and industrml electronic equipment.
Frederick C Foshag M R C win IR award In the I R 100 Competition, sponsored by the magazine Industrial Research, the 100 most significant research products introduced in a given year are chosen by the publication's editorial advisory board. A new field ion microscope (see Techmcal and Industrial Developments section of this issue) which allows researchers to actually see the positron of atoms on the surface of metals was among the 100 products selected in 1965 for the award. The field ion microscope was deyeloped by Materials Research Corporation (MRC) of Orangeburg, New York. This is the third consecutive year in which M R C has won a place m the I R 100 Competition. In 1963, the firm won the award for a cryogenic diffractometer attachment and in 1964 for a high pressure X-ray umt. Patent Office Library exhibition The Patent Office Library, the major British reference hbrary for the physical sciences, engineering and industrial technologies, will be staging an exhibztion of its scope and work during National Library Week from 14 to 19 March 1966, at the Patent Office, 25 Southamp.
