134 FLIGHT. AUGUST II, 1938. THE INDUSTRY (CONTINUED) New Utility Bearing A TYPE of needle bearing which is comparatively, new to this country is being introduced for aircraft use. It has as a background, it is stated, over 70 years' development by the American Torrington Company, and manufacture in Britain is contemplated. Torrington bearings have been used for various duties on road vehicles in this country. In aircraft they are visualised for all such points as control pivots, slots and flaps hinges, and undercarriage bearings. The bearing con sists of a number of needle-type rollers, retained at their tapered ends by a lipped-over hardened shell in a machined housing. The rollers surround a hardened inner race. Though having the characteristics of an >'' anti-friction'' bear ing, the Torrington bearing takes up only about the same space as a bronze or white- metal shell. The construction of the outer shell gives the bearing good grease-retaining qualities, and the bearings, which are made in various types (and, of course, in a wide range of sizes) are inexpensive. Alfred P. Mill, of Sentinel House, Southampton Row, Lon don, W.C.i, is the Torrington agent Donald Macpherson and Co. IT is stated that the fire which recently occurred at the Corn-' brook, Manchester, works of Donald Macpherson and Co., Ltd., makers of aircraft finishes, was not a serious one, and deliveries will not be affected. Contribution to Success SMALL but vitally important items in the equipment of the Short-Mayo Mercury when she made her Atlantic cross ing were the valve springs ot the Napier Rapier engine: These were the product of Herbert Terry and Sons, Ltd., of Red- ditch. Simplicity is a feature ot Torrington bearing. the PUBLICATIONS RECEIVED National Advisory Committee for Aeronautics : Report No. 617 : Auto-Ignition and Combustion of Diesel Fuel in a Constant-Volume Bomb, by R.
