Title: Managing combustion engine operation - is for maximum required power of aircraft starting generator using engine speed and throttle monitoring
Inventor: UHDE REINHART ING GRAD
IPC: G01R17/06
Filed: 1980-12-04
Abstract: A method of delivering the maximum necessary motor power for an internal combustion engine is for engines combined with generators to form current supplies to aircraft on the ground, esp. for starting aircraft engines. It enables better use to be made of the limiting power range of an engine by adjusting the electrical output power to the actual drive motor capabilities. The rate of revolution and the motor throttle actuator are monitored to determine whether the rate of revolution falls with load in the full throttle position. If a load dependent rotation rate drop occurs the generator output voltage is reduced so that the demanded motor revolution rate is maintained and stalling prevented. In normal operation the motor speed is held constant for varying load.

Title: Change-speed transmission for motor vehicles, comprising a main gearbox and a three-speed layshaft range-change gearbox
Inventor: PFANNKUCHEN AUGUST DIPL ING
IPC: F16H63/44
Filed: 1981-04-18
Abstract: A three-speed layshaft range-change gearbox with two shift clutches (K1 and K2) is connected downstream of a main gearbox which can be shifted by a hand lever. The range-change gearbox, in conjunction with the main gearbox, relays a reduction range, a direct range and a splitter range with a total of 12 forward speeds. In the reduction range, only one (K2) of the two clutches of the range-change gearbox is shifted. The position of the other clutch (K1) is arbitrary. As a result, when using a double H-shift with automatic transition between reduction range and direct range, and with a manually operated switch for the splitter unit, downwards shifting from a splitter speed to a speed of the reduction range is possible merely by operating the gear shifting lever. <IMAGE>
