Control system utilizing momentary switching devices

Abstract From the Canadian patent

A control system for a machine and the like having at least one cycle made up of at least two events utilizes momentary switching devices to actuate each cycle. The control system includes a control circuit having momentary switching devices digital circuitry for latching the control circuit in various modes of operation and timing circuitry, responsive to the digital circuitry for timing at least one event of the cycle; and a gate circuit controlled by semiconductor switching devices for regulating at least another event of the cycle in response to the control circuit.
