Abstract: A speed-responsive governor mechanism comprises a rotatable governor arrangement having an output member responsive to the speed of a shaft driving the governor arrangement. A lever has one end engaging the output member and has a cam surface at its other end. A further lever also has a cam surface which is opposed to the first mentioned cam surface. The cam surfaces are urged apart by a spring-loaded device which is rotatably mounted between them. The device has a pair of lever arms whch are biased outwardly by a tension spring and which engage the respective cam surfaces so that the force exerted by the first mentioned lever is dependent on the output position of the spring-loaded device.

Abstract: A device for preventing the simultaneous energization of electromagnetic coils used for driving the speed change gears in the automatic speed control system for an automobile, which device comprises resistors having one end thereof connected with the positive terminal of electromagnetic coils of electromagnetic valves, the other ends of the resistors being connected in common with the magnetic pole of a constant-voltage diode, and a power control circuit provided between a battery and a load, the positive pole of the constant-voltage diode being connected with the control signal input terminal of the power control circuit, whereby when two or more of the electromagnetic coils are about to be energized simultaneously, a current is passed through the constant-voltage diode to the control signal input terminal of the power control circuit to thereby cut off a current in the power control circuit and therefore the current to electromagnetic coils. The device is simple in circuit arrangement and free of the malfunction resulting from the qualitative irregularity of electrical components in use, or from variations in the ambient temperature or the source voltage.

Abstract: A servomechanism or pressure computer is shown which utilizes the jet nozzle servo principle. An input shaft is positioned for slight rotational movement within a sealed housing with the rotational position of the input shaft controlling the ultimate position of a jet nozzle which delivers servo fuel to either end of a power piston. Torque inputs are provided to the input shaft by a single input bellows, which operates against an evacuated bellows, and by a feedback spring which is connected to one end of the power piston. The servo jet nozzle is completely sealed with respect to the remainder of the servomechanism housing thereby preventing servo jet fuel from reaching the remainder of the mechanism. In operation, an input pressure is sensed by the bellows and thereby causes rotation of the input shaft and subsequent movement of the jet nozzle which repositions the power piston to a point wherein the feedback force generated through the feedback spring equals the input force generated by the bellows. The position of the power piston may be utilized to control any parameter, and in one embodiment, is utilized to control fuel delivery to an augmenter fuel system of an aircraft gas turbine engine.

Abstract: A hydraulic governor having a plurality of valve elements wherein one valve element produces a governor pressure inversely proportional to the centrifugal force operating this valve element, which governor pressure acts on a pressure receiving surface of another valve and the governor pressure generated by the latter valve element is balanced with the centrifugal force operating the latter valve element. This governor eliminates the unstability of control of the line pressure in response to the change of the governor pressure produced by the governor.

Abstract: Two fluid pulse signals of identical, r.p.m.-dependent frequency and of a predetermined relative time lag are applied to a fluid logic element to generate an r.p.m.-dependent output pressure which, in turn, is applied to a fluid amplifier element together with an arbitrarily variable fluid pressure. The amplified differential pressure is used directly to displace the fuel control rod of a fuel injection pump to increase or decrease the engine r.p.m.
