Title: Improvements in gears or gearing
IPC: F16H3/38
Filed: 1929-06-25
Abstract: 338,852. Potts, J. June 25, 1929. Variable-speed gearing ; clutches. - Between a toothed gear 20, Fig. 3, fixed to a shaft 21, and a sliding gear 34 are interposed a pair of intermediate gears 38, 39 to facilitate the toothed mesh. The gear 39 is loose and can turn freely relatively to gear 38 by the space of half the pitch, there being a pin-and-slot or like lostmotion connection 30, 31, Fig. 6, between them. The turning of gear 38 relatively to gear 20 is restrained by friction material 40, against which gear 38 is pressed by spring 44. When gear 34 is advanced, it picks up loose gear 39, but may be stopped by the ends of the teeth of gear 38 in position shown in Fig. 6. When gear 20 begins to move the faster, the teeth come into line and may be fully meshed. The forward ends of the teeth may be rounded to assist the action. In the case of clutch members 45, 46, Fig. 10, which are to be engaged, there are interposed intermediate gears 47, 48 with a like free lost-motion connection 30, 31 between them, and friction material 49 between gear 47 and clutch member 45. A variable-speed and reversing gear of the countershaft type embodying the invention is described.

A variable speed gearing for a vehicle providing a low drive range, direct drive and reverse, comprises a torque converter having an input driven impeller 2, a turbine 3 fast with the planet carrier 36 of a planetary gear and a reactor 4 connected by means of a one-way clutch 5 to the sun 38 of the planetary gear, which has a ring gear fast with an output shaft 37 and two intermeshing sets of planet pinions respectively meshing the sun and ring gears. A brake 9 is applied to station the sun 38 and hold the reactor one-way for low drive range, and a clutch 1 is engaged to directly connect the input shaft and the output shaft 37 for direct drive. Reverse is obtained by applying a brake 10 to station the planet carrier and turbine 3, the reactor 4 acting as a turbine and shaft 37 being driven in reverse. The brakes 9, 10 and clutch 1 are applied by hydraulic pressure supplied by a single input driven pump 6 under the control of a manual control valve 21.

Title: Improvements in or relating to the production of refractory metals
Inventor: WINTER CHARLES H

Abstract: 790,188. Extracting refractory metals. DU PONT DE NEMOURS & CO., E. I. July 2, 1956, No. 20432/56. Class 82(1) Refractory metals such as Ti, Zr, Nb, Ta, Hf, Mo, W are produced by reacting volatile chlorides, bromides or iodides thereof with a more electro-positive reducing metal such as Mg, Ca, Ba, Sr, Na, K, Li at a temperature above the melting point of the reducing metal within a closed reaction vessel 1 the reaction zone 8 of which is maintained out of contact with the vessel walls by cooling the walls to solidify the by-product halide salt formed. The wall of the vessel is surrounded by a cooling jacket 3 which by extraction of heat from the reaction vessel causes the formation of a solid retractable ingot 13 of by-product salt containing produced refractory metal which is continuously or intermittently withdrawn by means of retractor rolls 14. Refractory metal is recovered from the ingot so removed. The reaction may be started by forming an ingot of by-product halide on a closure plate fitted to the opening 12 of the vessel, volatile chloride and molten reducing metal being added through inlets 6 and 9 respectively to react and build up the. ingot which is then. withdrawn into engagement with rolls 14. Alternatively the initial by-product salt ingot may be melted in its central portion and refractory metal salt and solid reducing metal added to commence the reaction. In an alternative form the reaction vessel is tilted at an angle to the vertical to give a reaction zone of greater area and thereby to achieve a'greater reaction capacity and improved heat removal from the reaction zone which may be at a temperature between 750‹C. and 1400‹C.
