1. Time delay power controller apparatus which comprises:

  • (a) a power stage and means for connecting said power stage to a conventional power source;

    (b) a plurality of time delayed outputs;

    (c) a D.C. voltage bus and a ground;

    (d) a D.C. power supply connected to said D.C. bus;

    (e) a plurality of time delay timing stages connected between said D.C. bus and ground,each of said timing stages including a timer initiating voltage input line, a time delay voltage output line, a control relay connected to a corresponding one of the time delayed outputs and having an energizing coil connected to said time delay voltage output line and timing means connected between said timer initiating voltage input line and the time delay voltage output line for causing, a predetermined time interval after a change in voltage state appears on said timer initiating voltage input line, a voltage state change on said time delay voltage output line, said voltage state change on said time delay voltage output line causing the energizing of said control relay coil and thereby causing a time delayed control signal to be provided by the control relay to a corresponding one of the time delay outputs;

    (f) means for interconnecting said time delay timing stages in electrical series with one another, the time delay voltage output line of each said timing stage, except the last-in sequence one thereof, being connected to the timer initiating input line of the next-in-sequence one of the timing stages; and

    (g) means for changing the voltage state on the timer initiating voltage input line of the first-in-sequence one of the timing stages to thereby initiate the timing sequence.
