MAY II, 1939 FLIGHT. 489 OTES and NEWS Not-So-Minor ALTHOUGH the De Havilland Gipsy Minor engine is officially rated as a 90 h.p. unit, the first twelve standard engines leaving the factory were found to average a maximum output of 96.5 b.h.p. at 2,600 r.p.m. One of the engines actually developed 99.1 b.h.p. Fuel consumption, it is stated, was found to be well within the specified figures of 4 to 4^ gallons per hour when cruising at 2,250 r.p.ni. near sea level. The power developed under these conditions is equivalent to approximately 60 b.h.p, A Bearing Retirement AFTER being associated with the manufacture of Timken tapered roller bearings for twenty-three years, Mr. W. Dallow retired at the end of last month, and on his retirement he received a presentation from the staff. He was director and general manager of British Timken, Ltd. Mr. B. H. Riley, A.M.I.Mech.E., succeeds Mr. Dallow in the position of general manager. Contribution to Success ONE of the many firms intimately connected with the pro duction of the Handley Page Hampden is Gillett Stephen and Co., Ltd., who are manufacturers of oleo undercarriage parts (Vickers system). They are specialists in the produc tion of hydraulic equipment for aircraft in their factory at Bookham, Surrey, which has recently been equipped for this class of work with the most modern plant. Modernised Plant Increases Turnover SPEAKING at the ordinary general meeting of Thos. Firth and John Brown, Ltd., the Rt. Hon. Lord Aberconway, C.B.E. (chairman) said that during the last six years the company had spent nearly one and a half million pounds on modernising and extending its plant. It was now reaping the fruits of that expenditure both in increased capacity for out put and in economies of production. The same dividend would be paid as last year and the carry-forward would be increased. Needles with Possibilities FOR some time past there has existed the risk of needle roller bearings being assembled without their full com-, piement of rollers, due to the difficulty of retaining the rollers during the fitting operation. To overcome this difficulty the Ransome and Maries Bearing Co., Ltd., of Newark-on-Trent, have introduced needle rollers with a trunnion or shouldered ends instead of the familiar ball end. Where a complete needle rolled bearing is to be used, or where the rollers and the outer race only are to be employed, the usual form of race (in which the outer ring is provided with shoulders for guiding the rollers) is adopted. In the bore of these shoulders, pressings are fitted. The trunnions of the rollers rest on these pressings and are thus retained in the outer ring. If the rollers are requited to run between suitably hardened and ground surfaces without the introduction of separate race rings it is possible to overcome assembly problems by using a specially designed needle roller cartridge in which the rollers are held between end plates. A spring ring retains the assembly in position after the bearing is fitted C b & da and the thin metal cart- \ I / I I ridge has been removed.
