5io FLIGHT, 9 October 1953 THE INDUSTRY D.H. Propellers Appointment f\N October 1st, Mr. F. W. Long, C.B., joined de Havilland ^^ Propellers, Ltd. His duties will consist in liaison with users of the company's products at home and abroad. Mr. Long, who recently retired from the Royal Air Force with the rank of air vice-marshal, has had a long and distinguished Service career. He served in squadrons overseas in the early twenties and was for four years a Farnborough engine-test pilot, in which capacity he had much to do with the flight development of exhaust-driven and gear-driven superchargers and metal air screws. In 1928, flying a D.H.9R fitted with a turbo-supercharged Napier Lion, he attained a height of nearly 34,000 ft, an un official British record at the time. From Farnborough he went to Felixstowe as a member of the High-Speed Flight. His last appointment was as A.O.C. 23 Gp., Flying Training Command. Originality in Apprentice Awards AN original and appropriate form of award for apprentices whose work shows outstanding merit has been adopted by Kelvin and Hughes, Ltd., the well-known instrument manufacturers: The company's training panel now nominates successful candi dates among craft and technical apprentices for a month's course at the "Outward Bound" Sea School at Aberdovey. The first four winners are now at the school; they are D. H. Black and J. D. Martin, of the company's Barkingside factory, and D. J. Benham and A. J. Damoisiaux, from the Basingstoke Works. Bolt-and-nut Standards T^HE British Standards Institution has published a series of * Standards for a range of bolts and nuts, of Jin nominal size upwards, with UNF threads and with hexagon dimensions agreed for aircraft use between representatives of the American, British and Canadian Services and industries. This series of hexagon sizes differs from that of the "normal" series of Unified precision hexagon screws and nuts for general engineering purposes (covered by B.S. 1768:1951) in providing common dimensions for the hexagons of bolts and nuts of the same nominal size, and in the dimensions of hexagons for lin, fin and lin nominal-size bolts and nuts. Numbers, titles and prices of the specifications are: — A. 102, steel bolts (Unified hexagons and UNF threads) for aircraft, 4s; A. 103, steel nuts (Unified hexagons and UNF threads) (ordinary, thin, slotted and castle) for aircraft, 3s; A. 104, corrosion-resisting steel bolts (Unified hexagons and UNF threads) for aircraft, 3s 6d; A. 105, corrosion-resisting steel nuts (Unified hexagons and UNF threads) (ordinary, thin, slotted, and castle) for aircraft, 3s; A.106, aluminium- alloy bolts (Unified hexagons and UNF threads) for aircraft, 3 s 6d; ^Smjt^M ^ mjBrW<"^f3 R^kvll t JSB TIME-SAVER: Lunch at home in Bedford, a two-hour conference in Huddersfield, and home for tea, was the recent programme of Mr. N. Rodgers and Mr. M. Rodgers, of W. H. and J. Rodgers (Engineers), Ltd. They flew in an Auster J.SG Autocar some 120 miles from their own airstrip at Bedford to that of David Brown Tractors at Meltham, Yorks. They are here seen with (second from left) Mr. T. A. Lazenby and (extreme right) Mr. K. C. Wilson of David Brown. A. 107, aluminium-alloy nuts (Unified hexagons and UNF threads) (ordinary and slotted) for aircraft, 2s 6d; A.108, steel bolts (Unified hexagons, UNF threads and close-tolerance shanks) for aircraft, 3s. Copies of these standards may be obtained from the British Standards Institution, Sales Branch, 24 Victoria Street, London, S.W.I, at the prices given above. Trailers to Order THE design, supply and hire of mobile trailer units to serve a wide variety of purposes is the objective of a company recently formed. Various vehicles are available, designed for use as travelling showrooms, dispensaries, X-ray units, laboratories, tropical living quarters, and so forth. The hire fleet includes units arranged for publicity and entertainment purposes at air, engineering and agricultural shows. The new company, Pilgrim Motor Units, Ltd., has its head office and works at Ringwood, Hants (Ringwood 381) and a London office at 176 Piccadilly, W.l (Hyde Park 0479). The chairman is Maj. J. V. Phipps, M.A., who is also chairman of Pilgrim Caravans, Ltd., and the managing director is Mr. D. R. Hobson, O.B.E., formerly a senior executive of Anglo-Iranian. IN BRIEF THE firm of Petbow, Ltd., of Sandwich, Kent, state that one of their ground power units has been in use for starting the Olympus-Vulcan at Woodford. The unit was taken to Farn borough Show to perform similar services for the big delta when it was demonstrated in the flying display. * • * To assist designers to select the most suitable Magnuminium alloys for particular requirements, a new booklet of data-sheets entided Magnuminium Technical Data has been issued by High Duty Alloys, Ltd., Slough, Bucks. Very detailed design-data for the most effective choice of Pioneer O-ring seals for numerous different applications is con tained in a new handbook published by the Pioneer Oilsealing and Moulding Co., Ltd., Come, Lanes. From Startrite Engineering Co., Ltd., Waterside Works, Gads Hill, Gillingham, Kent, comes a description of their new wood working saw-bench. Driven by a li h.p. electric motor, the machine has an llin diameter saw and a 3ft x 3ft worktable with feed and run-off rollers. Maximum cutting capacity is 44in. Ferrybridge Industries, Ltd. (Whitehouse Industries, Ltd.), announce that they have opened London premises which will carry stocks of the products of their Pollard Bearing Division and Philidas Self-locking Nut Division. Managing the new office—at 6 St. James Place, London, S.W.I (Hyde Park 9248-9)—will be Mr. W. F. Clay, and Mr. T. S. Nethersole will be in charge of matters concerned with technical sales. Using the electrical upsetting process for the pre-forming of drop-forgings for compressor blades, the Bristol Engine Division came up against the problem of protecting the surfaces of the up setting anvils, which have to withstand extremely high loadings at temperatures exceeding 1,000 deg C. It was solved by weld- coating the anvils with "Brightray," the well known 80/20 nickel- chromium alloy. Bristols, incidentally, pioneered the use of "Brightray" for engine valve-protection, before the war. MESSAGE-CENTRE: The com pact radio-control receiver— 6in x 6in x 10^in, weighing 10 lb—employed in the M.L. Aviation pilotless target air craft (described in "Flight" of August 28th). It was designed and manufactured under an M.o.S. contract by BEME Electronic and Marine Equip ments, Ltd., of Shipyard Estate, Hythe, Hants. Adcola Products, Ltd., Cranmer Court, Clapham High Street, London, W.4, announce an addition to their range of soldering- tools: it is an instrument designed for extremely fine work, such as the soldering of details in instrument movements, miniature rectifiers and similar assemblies.
