Abstract: A gear assembly for a motor vehicle includes first clutch configured to selectively couple an input shaft to an output shaft and a second clutch configured to selectively couple the input shaft to a planetary gear train. When the first clutch is activated and the second clutch is not activated, the input torque is transmitted from the input shaft to the output shaft such that the output torque relative to the input torque is a first gear ratio. When the second clutch is activated and the first clutch is not activated, the input torque is transmitted from the input shaft to the output shaft through the planetary gear train such that the output torque relative to the input torque is a second gear ratio. When neither the first clutch nor the second clutch are activated, the input torque is not transmitted from the input shaft to the output shaft.

Abstract: An automatic transmission for an automotive vehicle includes a traction drive variator having an input disc, an output disc, and rollers driveably engaged with the discs and adapted to vary continuously the ratio of the speeds of the output disc and input disc. The input disc is reversed and overdriven by a gearset whose ring gear is connected to an input shaft; carrier is held permanently; and sun gear drives the input disc. A planetary gear unit driven by the output disc produces a speed reduction in response to alternate engagement of a forward drive brake and reverse drive brake.

Abstract: A water spray quench process and apparatus for the hardening of steel agricultural discs and like articles with minimum warpage and maximum exposure to the quenching water. A steel article heated in a furnace to a temperature above its austenitizing temperature is moved horizontally into a quenching station, supported on several support pins below the article with a positioning member above the article, and sprayed with water from a series of nozzles both above and below the article to rapidly and effectively quench the article to a minimum temperature. Once the article has been cooled by the quenching water, it is expelled from the quench station.
