Pulse-type regulating system for generators

Claim 1

IN A SYSTEM FOR MAINTAINING A DESIRED LEVEL OF OUTPUT POTENTIAL FROM A POLYPHASE ALTERNATING CURRENT GENERATOR HAVING A CONTROL WINDING TO CONTROL THE LEVEL OF OUTPUT POTENTIAL, THE COMBINATION OF A SENSING CIRCUIT CONNECTED TO SENSE THE GENERATOR OUTPUT POTENTIAL AND INCLUDING MEANS FOR DERIVING A UNIPOLAR SIGNAL FROM THE OUTPUT POTENTIAL, AND MEANS FOR MIXING A CONSTANT POTENTIAL WITH SAID UNIPOLAR SIGNAL TO DERIVE THEREBY A BIPOLAR SIGNAL; A SATURABLE CORE PULSE GENERATING CIRCUIT CONNECTED TO RECEIVE SAID BIPOLAR SIGNAL AND OPERATIVE TO PRODUCE A RECTANGULAR PULSE OF PREDETERMINED TIME DURATION WHENEVER SAID BIPOLAR SIGNAL CHANGES TO A CERTAIN POLARTY; AND A PLURALITY OF CONTROLLED RECTIFIERS EACH CONNECTED BETWEEN A DIFFERENT PHASE OF THE GENERATOR OUTPUT POTENTIAL AND THE CONTROL WINDING, EACH OF SAID CONTROLLED RECTIFIERS HAVING A GATE ELEMENT SO CONNECTED TO RECEIVE SAID RECTANGULAR PULSES AND FIRE ONLY THE ONE OF SAID CONTROLLED RECTIFIERS ASSOCIATED WITH THE MOST POSITIVE INSTANTANEOUS PHASE POTENTIAL, THEREBY PROVIDING A QUANTITY OF ENENRGIZATION TO THE CONTROL WINDING INVERSELY RELATED TO THE GENERATOR OUTPUT POTENTIAL.
