Claims

1. A VOLTAGE REGULATING CIRCUIT COMPRISING A VARIABLE IMPEDANCE MEANS IN SERIES WITH THE OUTPUT OF SAID REGULATING CIRCUIT, VARIATION MEANS FOR VARYING SAID IMPEDANCE MEANS, A FIRST AND A SECOND CONSTANT VOLTAGE DROP MEANS, EACH HAVING AN ADDITIONAL IMPEDANCE IN SERIES THEREWITH ACROSS SAID OUTPUT, SAID ADDITIONAL IMPEDANCES BEING CONNECTED TO DIFFERENT SIDES OF SAID OUTPUT, A FIRST AND A SECOND CURRENT AMPLIFYING MEANS, EACH HAVING A CONTROL TERMINAL, THE CONTROL TERMINAL OF ONE OF SAID AMPLIFYING MEANS BEING CONNECTED TO THE JUNCTION OF ONE OF SAID CONSTANT VOLTAGE DROP MEANS AND ITS RESPECTIVE ADDITIONAL IMPEDANCE, THE CONTROL TERMINAL OF THE OTHER SAID AMPLIFYING MEANS BEING CONNECTED INTO THE SERIES CIRCUIT INCLUDING THE OTHER OF SAID CONSTANT VOLTAGE DROP MEANS, THE OUTPUT OF THE FIRST SAID AMPLIFYING MEANS BEING CONNECTED TO A SIMILAR TERMINAL OF THE SECOND SAID AMPLIFYING MEANS, THE OUTPUT OF THE SECOND SAID AMPLIFYING MEANS BEING OPERABLY CONNECTED TO SAID VARIATION MEANS, AND AN ADDITIONAL CURRENT AMPLIFYING MEANS HAVING A CONTROL TERMINAL, THE OUTPUT OF SAID ADDITIONAL CURRENT AMPLIFYING MEANS BEING ALSO CONNECTED TO THE OUTPUT OF SECOND SAID AMPLIFYING MEANS, THE CONTROL TERMINAL OF SAID ADDITIONAL CURRENT AMPLIFYING MEANS BEING CONNECTED TO THE UNREGULATED SIDE OF SAID VOLTAGE REGULATOR.
