6l2 FLIGHT. JUNE 4, 1936. The Moffett Trophy Trials THE eliminating trials for the choosing of six models to represent Great Britain in the contest at Akron for the Admiral Moffett Trophy were held on tlie same occasion as the Wakefield Trials. The results were as'follows :—H. Simmons (Blackheath M.F.C.), best of three rise-off-ground flights, 199.75 sec; A. Worley (Northern Heights M.F.C.), 117 sec. W. Worden (T.M.A.C.). 106; C. Gibson (N. Kent M.A.S.), 105.5; G. Merrifield (Bournemouth M.A.S.), 104; K. M. Francis (Wembley M.F.C.), 102.4. The six models will be taken to America and flown by the British Wakefield Team. T.M.A.C. Wimbledon Rally TFIE 10th Group of T.M.A.C. will hold their second annual rally at Wimbledon on July 5, from 11 a.m. till dusk. All modellists are invited, and can enter the contests at a small fee. The six contests are for general duration (all types, " spais " included), heavyweights (5 oz. loading and over), scale models to any scale, gliders, seaplanes (using the port able tank), and an inter-club team competition. Further information can be obtained from the Group Leader and Organiser, Mr. C. H. Orchard, 26, Tennyson Avenue, Motspur Park, Surrey. * * . * . The latest edition of The Green Book, 4d. post free from Model Aircraft Supplies, Ltd., 171, New Kent Road, London, S.E.i, not only contains a catalogue of their various model materials brought up to date by judicious elimination and the inclusion of sundry new items, but a wealth of sound informa tion on design and construction. * « * T HE revised edition of The Boys' Book of Model Aeroplanes, by Francis A. Collins, published at 6s. by the D. Appleton- Century Co., contains a lucid explanation of flight, and much useful constructional information, but more drastic revision would be an improvement. In particular, the references to the Wright and Bleriot machines as if they were existing types is confusion and tends to give a wrong impression of the value of the book as a whole. Industrial Gases FEW people in the aircraft industry need any introduction to the products of the British Oxygen Company, especially 111 the matter of oxygen and acetvlene for welding. On the other hand, members of each individual industry using the Company's products are understandably ignorant of the wide field it covers in other industries. Some idea of the extent of this field was obtainable during a visit last week to the company's fine new offices, which occupy one of the vast floors of Thames House, Westminster. It was revealed that in addition to the familiar oxygen and acetylene, the B.O.C. manufactures and compresses hydrogen, coal gas, nitrogen, carbon dioxide, nitrous oxide, argon, helium, neon, ethylene, and numerous mixtures of various of these gases, a surprising number of them, incidentally, being required for medical purposes. When it is added that the Company also manufactures much of the equipment which the use of these gases involves, one begins to appreciate why it has no fewer than thirty-three factories and twenty- two depots in the British Isles, and many allied companies overseas. Facilitating Bearing Production BRITISH TIMKEN, LTD.. well known as manufacturers of tape 1 1 roller bearings, the fundamental principal of which bearing embodies the ability to absorb a combination of thrust and radial load, have received increasingly heavy demands for large-capacity bearings and in consequence have been compelled to formulate new production programmes. Consultations, which have taken place between the engineers of British Timken, Ltd and the Churchill Machine Tool Co., Ltd., over a period of two years, have resulted in the installa tion of a precision grinding machine which has not only the ability to handle large diameter cups and cones in single operation, but gives a considerable range in diameter and length not as yet fully expounded. In addition, the machine is capable of grinding internal and external surfaces, spherical end faces and ball tracks. The grinder, which has now been in operation for several weeks at the Birmingham works of British Timken, Ltd. is at the present moment working with experimental grinding wheels, and it is stated that even on these wheels the reduc tion in grinding time, as compared with the machines used hitherto, is amazing. It is claimed that, at a rough estimate, as much as 75 per cent, reduction in grinding time has been effected.
