Hydulignum-Jabroc (Tools), Ltd., with registered offices atHydulignum Works, Haddenham, Bucks, and works at Mill Lane, Waddon, Croydon, Surrey, will manufacture metal forming toolsand jigs for the aircraft and engineering industries. This com- pany will combine the tooling businesses in laminated densifiedwood, metal and other materials formerly conducted by Hordern- Richmond, Ltd., Jablo Plastics Industries and Moulded Compo-nents (Jablo), Ltd. Re-equipment and extension of the Croydon works will provide a substantial increase to existing capacity.Directors are A. A. Heath, M.A., M.I.E.E.; J. H. Collins, B.Sc, F.R.I.C.; B. Jablonsky, A.F.R.Ae.S.; Lord Selsdon, D.S.C.; J.Watson, F.C.I.S. Jabroc, Ltd., with registered office and works at Mill Lane,Waddon, will continue the manufacture of Jabroc densified wood laminates, in accordance with existing manufacturing specifica-tions. Arrangements have been made for the completion of all open contracts placed with Jablo Plastics Industries and MouldedComponents (Jablo), Ltd., and for the future sale of Jabroc material. Directors arc H. Howarth, J. H. Collins, B. Jablonskyand Lord Selsdon. Starting and Towing A PARTICULARLY useful form of ground power unit is the**- self-propelled type, which can also be used to move aircraft. Three such starting and towing units have been supplied for theRoyal Iraqi Air Force, by Aerocontacts (Ground Equipment), Ltd., Gatwick Airport, Horley, Surrey. The vehicles, which were manufactured by Red Devon, Ltd.,of Totnes, are larger (14ft 6in long X 6ft 3in wide) than the accompanying illustration would suggest, but they are only 4^fthigh, and can therefore be driven under the wings and fuselage of large aircraft. Two models are available. One, with either adiesel or Ford V.8 petrol engine, can deliver a continuous 28.5 V output of 600 amp for general servicing, and a peak capacity of1,650 amp for starting purposes. The second, and larger, model is available as a diesel unit only;it is capable of a continuous 800 amp output, with a peak capacity of 2,000 amp. Three of the starting and towing units, similar to those supplied to the Royal Iraqi Air Force by Aerocontacts (Ground Equipment), Ltd. Contested by 45 Goodyear factories all over the world, the Hinshaw Safety Trophy has been won by the company's aviation division at Wallasey, Cheshire, which in 1954 completed 642,732 man-hours with- out recording a lost-time accident. Mr. H. L Ginaven (right), produc- tion director, Wolverhampton and Wallasey, presented the award to Mr. C. J. Thomas (left), Wallasey plant superintendent. - Vibrations to Order ~T\ESIGNED for the investigation of vibration phenomena in-•-' the products of the aircraft, electronic and other industries, a range of vibration generators is manufactured by GoodmansIndustries, Ltd., Axiom Works, Wembley, Middlesex. Apparatus of this type is, in effect, an electro-dynamic exciter, employing amoving coil operating in a strong magnetic field to provide the physical vibration; this is then controlled by matched electronicdriving equipment which accurately determines its amplitude, frequency and force. For some time past, four models have been available, coveringa frequency range of from 3,000 to 10,000 c.p.s., and with peak thrusts of from 2 lb to 300 lb. To these has lately been added anew unit, designated Model 16/600, capable of exerting a maxi- mum thrust of 500 lb (27 lb/amp) over a frequency range of upto 1,000 c.p.s. Like the other models, the 16/600 is supplied with a trunnion mounting which provides a choice of angles for thedriving shaft. To the range of driving equipment, also, a new model has beenadded. Known as the D.120, and providing an output of 120 W over a wide frequency-range, it has been designed for use withthe Goodman Model 390A generator (25 lb peak thrust, frequency to 10,000 c.p.s.). New Shell Films ^SJ-J^JZ^r A TELLING impression of the size of the oil industry, andof the way in which discovery of oil affects a countryside and its people, is given in The Oilmen, a recent addition to the Shellfilm library. In Proud Ships—another new Shell film—the story of an individual vessel and its men is cleverly interwoven with anaccount of tanker operations in general. Proud Ships is obtainable now, and The Oilmen will be available shortly, on loan fromPetroleum Films Bureau, 29 New Bond Street, London, W.I. Both are sound films, and have been made in 16mm and 35mm sizes. IN BRIEF At its annual meeting, to be held on July 15th, the R.F.D.Co., Ltd., and its subsidiaries will report a 1954 profit of £53,751 after deduction of tax, as against £37,150 for the previousyear. A final dividend of 10 per cent, less tax, is recommended. * * * Details of two one-day conferences on the theme "FuelEfficiency Pays" have been announced. They are to be organized by the East Anglian Regional Advisory Council forFurther Education, in conjunction with the National Industrial Fuel Efficiency Service, and will take place on July 13th at Norwichand July 14th at Cambridge. There will be no conference fee. Further details can be obtained from Dr. F. Lincoln Ralphs,Secretary, East Anglian Regional Advisory Council for Further Education, Stracey Road, Norwich, or Mr. E.

It is announced that Ottico Meccanica Italiana, of Rome, haveappointed Photonic Equipment (London), Ltd., 9 Newman Street, London, W.I, as their United Kingdom agents. Ottico Meccanica—whose president, Dr. Umberto Nistri, was recently invited by the Photogrammetric Society to lecture in London—manufacturea large variety of air-survey cameras and precision plotting instru- ments for map-making. * * * The formation of a new company, Cossor Instruments, Ltd.,has been announced by A. C. Cossor, Ltd. The company will design and develop new instruments to meet the demands ofresearch and industry. The chairman is Lord Burghley, and Messrs. J. S. Clark, H. Chisholm, H. T.
