Abstract: A cam is capable of angular movement on a cam shaft. A disc eccentrically mounted on the shaft is driven from the shaft via a pin connection and drives the cam by a similar connection. The degree of eccentricity of the disc, which is adjustable, determines the acceleration and deceleration given to the cam as it rotates. There is disclosed an electro-mechanical servo system, responsive to the speed of an engine incorporating the cam and cam shaft, for controlling the eccentricity of the disc in dependence on the speed. Also disclosed is an electronic servo system for the same purpose.

Abstract: This invention relates to a speed responsive system for a motor vehicle whereby the vehicle may be kept at a predetermined speed, or the driver may be warned when a predetermined speed is reached. In one embodiment, the system includes an inductive pick-up or transducer, which senses rotation of a ferrous-toothed disc rotatable with a shaft to generate a voltage dependent upon the rotational speed of the shaft. Means, comprising a potential divider or a memory circuit, are provided for generating a reference voltage, and a comparator circuit is provided for comparing the voltages, the comparator being arranged to emit or change its output signal when the speed responsive voltage, or a voltage derived therefrom, reaches the reference voltage.
