Electronic current regulator

Claim 1

AN ELECTRONIC CURRENT REGULATOR FOR USE WITH A GENERATOR HAVING AN ARMATURE CIRCUIT, A FIELD CIRCUIT, AND FIELD CURRENT CONTROL MEANS TO CONTROL THE FLOW OF CURRENT TO SAID FIELD CIRCUIT, SAID CURRENT REGULATOR COMPRISING FIRST RESISTANCE MEANS CONNECTED IN SERIES WITH SAID ARMATURE CIRCUIT FOR DEVELOPING A FIRST VOLTAGE THEREACROSS WHICH VARIES WITH VARIATIONS IN ARMATURE CURRENT, BIAS CIRCUIT MEANS CONNECTED ACROSS SAID ARMATURE CIRCUIT FOR DEVELOPING A REFERENCE VOLTAGE, CONTROL CIRCUIT MEANS CONNECTED TO SAID FIRST RESISTANCE MEANS HAVING A CURRENTVOLTAGE CHARACTERISTIC EXHIBITING BOTH POSITIVE AND NEGATIVE RESISTANCE CHARACTERISTICS AND CONDUCTIVE AND NONCONDUCTIVE STATES, OUTPUT CIRCUIT MEANS CONNECTED BETWEEN SAID CONTROL CIRCUIT MEANS AND SAID FIELD CURRENT CONTROL MEANS FOR CONTROLLING SAID FIELD CURRENT CONTROL MEANS IN RESPONSE TO NON-CONDUCTION OF SAID CONTROL CURRENT MEANS, AND SECOND RESISTANCE MEANS INTERCONNECTING SAID BIAS CIRCUIT MEANS AND SAID CONTROL CIRCUIT MEANS, THE DIFFERENCE VOLTAGE BETWEEN SAID REFERENCE VOLTAGE AND SAID FIRST VOLTAGE BEING APPLIED AS A VOLTAGE SOURCE TO SAID CONTROL CIRCUIT MEANS AND SAID SECOND RESISTANCE MEANS BEING CONNECTED AS A LOAD FOR SAID CONTROL CIRCUIT MEANS SO AS TO EFFECT SWITCHING OF SAID CONTROL CIRCUIT MEANS FROM SAID CONDUCTIVE TO SAID NON-CONDUCTIVE STATES UPON INCREASE IN ARMATURE CURRENT BEYOND A PREDETERMINED LEVEL EFFECTING VARIATION IN SAID DIFFERENCE VOLTAGE.
