Abstract: THE FUEL RACK OF A FUEL INJECTION PUMP IS REGULATED AS A FUNCTION OF THE ENGINE R.P.M., THE POSITION OF THE ARBITARILY OPERATED BUTTERFLY VALVE AND OTHER OPERATIONAL VARIABLES. FOR THIS PURPOSE AN ELECTRIC SIGNAL REPRESENTING A DESIRED VALUE IS DERIVED FROM THE ANGULAR AND AXIAL POSITIONS OF A THREE-DIMENSIONAL CAM (WHICH ASSUMES ITS POSITION IN RESPONSE TO AN ELECTRIC SIGNAL CHARACTERIZING THE ACTUAL ENGINE R.P.M. AND IN RESPONSE TO A MECHANICAL SIGNAL CHARACTERIZING THE ACTUAL POSITION OF THE BUTTERFLY VALVE) AND IS COMPARED WITH AN ELECTRIC SIGNAL REPRESENTING AN ACTUAL VALUE DERIVED FROM THE ACTUAL POSITION OF THE FUEL RACK. THE ELECTRIC SIGNAL RESULTING FROM SAID COMPARISON IS APPLIED TO A CONTROL MEMBER WHICH IS DISPLACED ACCORDINGLY AND WHICH, BY VIRTUE OF ITS CONNECTION WITH THE FUEL RACK, CAUSES A CORRESPONDING MOVEMENT OF THE LATTER. ELECTRIC CORRECTING SIGNALS REPRESENTING PHYSICAL
MAGNITUDES, SUCH AS ENGINE TEMPERATURE AND ATMOSPHERIC PRESSURE, VARY THE DESIRED AND/OR ACTUAL VALUE SIGNALS PRIOR TO THEIR COMPARISON.-

Abstract: An AC tachometer has two output windings, each connected to one input of the same bistable circuit. A rectifier and filter circuit or a Zener diode is interconnected between each output winding and bistable circuit input. When the voltage at the bistable inputs exceeds a predetermined magnitude, the bistable input flips to the second stable state. A signal resulting from the change in state can be used to cut off fuel supply to stop the engine.
Abstract translation: 交流转速表有两个输出绕组，每个输出绕组连接到同一双稳态电路的一个输入端。 整流器和滤波器电路或齐纳二极管在每个输出绕组和双稳态电路输入之间互连。 当双稳态输入端的电压超过预定值时，双稳态输入转为第二稳定状态。 可以使用由状态改变引起的信号来切断燃料供给以停止发动机。
