ABSTRACT:
An electronic timer for selectively timing the occurrence of electrically controllable events. The relative time spacing of events to be timed is stored or programmed in a memory by proportional storage in memory locations. This having been accomplished, execution of the program is effected by means of a selectable rate pulse generator which interrogates the memory. At those locations where positive data is stored, there results an output which is employed to perform a switching function.
