IN COMFORT AIRCREW headsets are a speciality of Amplivox, Ltd.- (Industrial Products Division), 2 Bentinck Street, London, W.I. Equipment they are now supplying to B.E.A., the M.T.C.A., and other users employs lightweight head- phones of the same general arrangement as the American HS 33 type, together with a boom - mounted microphone de- veloped by Ampli- vox to the require- ments of B.E.A. (Though it is the usual description, the word "boom" is perhaps uncompli- mentary to the neat curved rod which, from a point above one phone, posi- tions the micro- phone near the mouth; the microphone diameter is -fin, depth |in and the weight \ oz; total weight of the attachment is 3i oz.) The headphones employ a pair of fully tropicalized magnetic diaphragm inserts of light weight and original design. Standard impedance of each unit is 300 Ohms, giving 600 Ohms total when series-connected or 150 Ohms in parallel. Alternative low-impedance windings are available to special order. All the usual provisions for headband adjustment and comfort are made. The microphone and boom can, if desired, be supplied for fitting to such existing headsets as the American HS 33 or Marconi-Brown No. 1573. MINIATURE-VISCOUNT PRODUCTION THIS highly finished *- l/72nd-scale display model of a Viscount is one of a quantity-produced series for B.E.A., moulded in polystyrene by Insulators, Ltd., of Totten- ham. A remarkable fact is that the complete aircraft—which is hollow—is, with the exception of the four engine nacelles, moulded in a single tool. In this one mould are four cavities, for front and rear fuselage halves and for the two wings. The Insulators, Ltd., Viscount. S/L. D.

D.H. PROPELLERS APPOINTMENT CHIEF aerodynamicist of de Havilland Propellers, Ltd., since1951, Mr. P. Brett, B.Sc., (Hons.) A.F.R.Ae.S., D.L.C., has been appointed chief project engineer of the Company. He has been responsible, it is stated, for the aerodynamic design of de Havilland airscrews for all the new British engines now build- ing, and his experience will now be extended to wider fields of design and engineering, and to the surveying of industry's and operators' requirements. Mr. Brett first joined the aero- dynamics department of de Havilland Propellers in 1944. After a period at London Uni- versity he went to B.O.A.C., returning to D.H. Propellers in 1950. He was appointed chief aerodynamicist in January 1951. Mr. P. Brett. INDUSTRY NEWS IN BRIEF - Mr. M. N. Golovine, M.B.E., A.C.G.I., A.F.R.Ae.S., formerly aero sales director of Armstrong Siddeley Motors, has been appointed Director of A.T.S. Co., Ltd., a company of the Hawker Siddeley Group specializing in consultant and market survey work. * * * Mr. Michael Clark, director of the Electronics and Equipment Group of the Plessey Co., Ltd., is visiting the United States to study new developments there in the field of electronics and telecommunications. * * * Air Trainers, Ltd., announce the appointment of Mr. L. Malec, M.B.E., A.F.R.Ae.S., to their Board of directors. Mr. Malec joined the company from B.E.A. in 1948 as technical adviser and in 1952 became joint general manager. Since then he has been responsible for commercial activities as well as for production. * * * For many years past, the firms of Smith-Clayton Forge, Ltd., of Lincoln, and William Jessop and Sons, Ltd., of Sheffield, have maintained friendly relations, and during that time Smith-Clayton have been forging turbine and compressor discs from Jessops' temperature-resisting materials. Last week it was announced that the two companies had "entered into a long-term agreement to ensure the continuance of this trading relationship." * * * Primarily in order to give employees in Dunlop factories, both in Great Britain and abroad, an understanding of the origin of the material which they fabricate, a film has been made under the title Dunlop in Malaya. Depicting the work of the company's 13 estates centred on Malacca, it shows in detail how die rubber is processed for shipment from the time when the latex is first tapped from the trees. Copies of the film are available on loan to engineering societies, etc., from Fort Dunlop, Birmingham.
