    Abstract: A pair of storage condensers having charging and discharge circuits, and a change-over circuit therebetween, are interconnected under control of a monostable multivibrator so that, when the monostable multivibrator is triggered into unstable state by input pulses, the trailing edge of the flanks of the pulses therefrom are connected to the charging circuit for one of the condensers to charge the condenser; and, connected to the discharge circuit to activate the discharge circuit and permit discharge of the condenser during the reset time of the monostable multivibrator and, additionally, to the change-over circuit to selectively block the change-over circuit. To provide good linearity, a function generator, preferably a dioderesistance network having an approximately parabolic or hyperbolic transfer function interconnects the storage condenser and the discharge circuit therefor. The monostable multivibrator is so connected that an output transistor thereof simultaneously forms part of the discharge circuit, to reduce the number of required components.

    Abstract: A regulating arrangement for internal combustion engines, particularly of the diesel-engine type. The fuel injection pump is set and displaced through an amplifier having one signal input derived from a speed sensor coupled to the crank shaft of the engine. The input of amplifier may also be fed with a signal derived from the accelerating pedal of the engine. A hydraulic displacement device between the output of the amplifier and the fuel injection pump converts the electrical signal from the amplifier into a corresponding setting of the pump. The feedback network of the amplifier is such that the amplification of the amplifier is substantially high at idling speeds of the engine.

    Abstract: THE POSITION OF A POSITIONING MEMBER WHICH CONTROLS THE AMOUNT OF FUEL TO BE INJECTED INTO AN INTERNAL COMBUSTION ENGINE IS DETERMINED BY DRIVING A SIGNAL REPRESENTATIVE OF ENGINE SPEED, MODIFYING THE SIGNAL TO OBTAIN AN OUTPUT REFLECTING ENGINE CHARACTERISTICS, AND THEN CONTROLLING WITH THE MODIFIED SIGNAL THE POSITION OF A CAM, PREFERABLY A THREE-DIMENSIONAL CAM, THE POSITION OF THE CAM BEING ADDITIONALLY CONTROLLED BY THE POSITION OF THE ACCELERATOR FOR THE ENGINE. A SIGNAL IS DERIVED FROM A CAM FOLLOWER, AND THIS SIGNAL IS ADDITIONALLY AFFECTED BY A CORRECTION UNIT CORRECTING FOR CHANGES IN AMBIENT AIR PRESSURE, TEMPERATURE OF THE ENGINE, OR AMBIENT CONDITIONS, OR THE LIKE, SO THAT THE FINAL OUTPUT CONTROLLING THE SETTING OF THE POSITIONED MEMBER WHICH DETERMINES THE AMOUNT OF FUEL INJECTED WILL BE REPRESENTATIVE OF ENGINE CHARACTERISTICS, THE ACCELERATOR POSITION, AND AMBIENT CONDITIONS AS SENSED BY THE CORRECTION UNIT.

    Abstract: A servo loop for correcting the position of a piston operating against a load has a control unit comprising a three point regulator for operating two on-off valves and a pulse length modulator for operating a switch over valve, the on-off and switch over valves being connected to the piston cylinder, a pressure tank, and a collection tank, so as to move the piston in either of two directions. The three point regulator and the pulse length modulator are driven by the difference between the desired signal and the actual signal, the latter being obtained from an inductive displacement pickup coupled to the piston rod.
