Multiple time delay power controller apparatus

Abstract From the Canadian patent

Multi-time delay power controller apparatus for providing time-delayed power or control signals to associated electrical equipment, such as computers and disc drives, comprises a power stage configured for connecting to a conventional power outlet a D.C. power, supply connected to an interval D.C. voltage bus an out-, put stage having a plurality of time delayed outputs and a plurality of time delay timing stages connected in electrical series to one another between the D.C. voltage bus and ground. Each such timing stage includes a timing circuit, a comparator circuit and a normally open control relay. Coils of odd numbered timing stages are connected to ground and of even numbered stages …
