TL;DR: In this article, a power supplying member supplies rotational power in a certain rotational direction to an input member of the transmission, and a power receiving member takes out power from a driven gear wheel shaft.
Abstract: A power supplying member supplies rotational power in a certain rotational direction to an input member of the transmission, and a power receiving member takes out power from a driven gear wheel shaft. Two driving gear wheel shafts extend parallel to the driven gear wheel shaft. First and second driving gear wheels are respectively rotatably mounted on the first and the second driving gear wheel shaft and meshed with a common driven gear wheel fixedly mounted on the driven gear wheel shaft. First and second synchromesh devices respectively selectively engage the first and the second driving gear wheel to the first and the second driving gear wheel shaft. First and second clutching mechanisms, each of which either can be disconnected so as to freewheel in both rotational directions or can be connected in the one rotational direction which is required for transmission of power through that clutching mechanism from the power supplying member rotating in the certain rotational direction so as to function as a one way clutch, are mounted to selectively transmit rotational power between the input member and the first and second driving gear wheel shafts respectively, both proximate to ends of the first and second driving gear wheel shafts closer to the input member.

TL;DR: In this paper, a gear pump for use in a metered liquid dispensing system utilizes a pair of carbon graphite wear plates to increase pump vacuum or suction lift capabilities.
Abstract: A gear pump for use in a metered liquid dispensing system utilizes a pair of carbon graphite wear plates to increase pump vacuum or suction lift capabilities. The wear plates are disposed on opposite sides of the pump spur gears and are biased against the sides of the gears to reduce internal pump clearances. The biasing force is provided by a resilient O-ring positioned between a surface of the pump housing and one of the wear plates. The gears are mounted for limited movement so the urging of the one wear plate is transferred through the gears to the other wear plate. The gear pump is driven through a gear reducer unit by a reversible electric motor. The use of a gear pump assures accurate metering of the amount of fluid delivered by the system.

TL;DR: In this article, the upper and lower plates of a gear train are mounted with radial ports through which oil collected in the recessed area flows to the bearing and working parts before returning to the sump.
Abstract: A gear train is housed in a gear box having upper and lower plates in or on which gear-shaft bearings are mounted. One of the gears functions as a centrifugal gear pump for projecting lubricating oil from a sump in the tank angularly upwardly through openings in the upper bearing-mounting plate to a deflecter plate located thereabove. This oil is deflected angularly downwardly and collected in a recessed area on the upper surface of the upper bearing-mounting plate. Bearing caps are provided with radial ports through which oil collected in the recessed area flows to the bearings and working parts before returning to the sump.
