Title: Improved variable-speed power transmission mechanism for motor vehicles
IPC: F16H47/08
Filed: 1956-08-23
Abstract: 793,346. Change-speed control. GENERAL MOTORS CORPORATION. Aug. 23, 1956 [Sept. 16, 1955], No. 25773/56. Addition to 750,788. Class 80 (2). To prevent slip of fluid-pressureapplied brakes and clutch 30, 38, 36 of a two-speed and reverse planet gear on a vehicle, due to temporary reduction of servo pressure when fluid pressure is supplied under accelerator control 72 to change the inclination of the reactor blades 84 of a hydrodynamic torque converter 12 through which the gear is driven, a main pressure regulator valve 102 shuts off at 126 the supply-line 124 of the torqueconverter and blade-angle servo whenever main supply pressure 96 falls below a predetermined value set by a regulator loading spring 108. Regulator-valve loading is increased in low and reverse. Pressure in a regulator-valve chamber 104, supplied through one-way valves 98, 100 by input- and output-driven pumps 90, 92 is regulated to exhaust 142. The torque converter is fed at 66 from the regulated pressure line 124 through a restrictor 132, which, in conjunction with a pressure relief valve 134 in the converter exhaust, maintains a converter working pressure always lower than regulated pressure. This reduced pressure 66 is also fed continuously to the right face of a piston 58 which adjusts the inclination of the reactor blades 54 through a crank 56, as described in Specification 773,954, pressure 66 tending to move the blades to a high angle position for maximum torque multiplication. Unreduced regulated pressure 124 is fed direct at 85 to the left face of the blade-shift piston 58 to overcome the reduced pressure 66 and maintain a low angle blade setting for minimum torque multiplication in normal running, unless, by overtravel of the accelerator 72 beyond full throttle, a valve 80 is depressed to exhaust the line 85 and permit the pressure 66 to enforce high angle. Should pressure in the servo main 96 fall below that necessary to prevent slip of the gear brakes and clutch, the regulator valve 102 is moved left by the spring 108, shutting off at 126 the converter and blade shift line 124 until pressure again rises. The gear brakes and clutch are fed through a manual distributer valve 122, and the servos of the lowspeed brake 38 and reverse brake 30 communicate with regulator-valve loading chambers 152, 156 respectively for pressure augmentation in low and reverse.

A magnetic material comprising two magnetic components, one being metallic and the other oxidic, is made by oxidizing the surface of metal particles, mixing the particles with oxides or oxide forming substances, and converting the admixture into a magnetic composition into which the oxide coatings are integrated. The metal particles may be of iron or alloys of iron with nickel or cobalt, and oxidized by the action of air and water, or by heating in oxygen or carbon dioxide or steam. The added materials may be oxides, carbonates or oxalates of bivalent metals such as nickel and zinc when a soft magnetic material is desired or of barium, strontium or lead to produce a hard magnetic material. After compressing to a compact body, the mixture is heated to produce by sintering ferrites from the oxide coatings and added materials. The sintering may be in an inert gas such as nitrogen or argon. In producing permanent magnets, the oxidization of the metal particles may be continued until the iron constituents are so small that they exhibit permanent magnetic properties in virtue of their size. Specification 590,392, [Group II], is referred to.
