Abstract
A control system for a cyclically operating machine is disclosed wherein one or more operations are to be performed during each successive machine cycle. Signal generating means or a voltage generating means proportional to machine speed establish a sequence of signals or a voltage during each machine cycle, for producing a charge. An initial charge level or voltage is established, which can have a value of either a zero voltage or some other predetermined voltage at the beginning of each cycle. The voltage is changed as the signals are received or voltage is generated until a second predetermined voltage is reached, which can be either higher or lower than the initial voltage, at which time a control signal is emitted which may perform an operation associated therewith, such as by starting or stopping a machine motion. Adjusting means are provided to control the rate of change of voltage level and thereby change the point or time in the machine cycle at which the second voltage is reached, and thus vary the time within a cycle at which the operation associated therewith with occur.
