Saturable power modulator

Claim 1

IN A POWER MODULATOR FOR CONTROLLING POWER DELIVERED FROM AN A.C. SOURCE TO A LOAD OVER A PREDETERMINED NORMAL CONTINUOUS RANGE OF OPERATION, THE COMBINATION INCLUDING A HIGH LEAKAGE REACTANCE TRANSFORMER CORE HAVING A FIRST LOOP PATH THEREIN FOR MAGNETIC FLUX AND SAID CORE HAVING AT LEAST ONE MAGNETIC SHUNT PATH WITH AN AIR GAP THEREIN FOR BYPASSING A PORTION OF SAID FIRST LOOP PATH IN SAID NORMAL CONTINUOUS RANGE, PRIMARY WINDING MEANS ON SAID CORE HAVING A PAIR OF INPUT TERMINALS FOR CONNECTION TO THE A.C. SOURCE FOR PROVIDING PRIMARY FLUX IN SAID FIRST LOOP PATH, AN EXTENSION OF SAID PRIMARY WINDING MEANS ON SAID CORE CONNECTED IN CIRCUIT IN SERIES WITH SAID PRIMARY WINDING MEANS, SECONDARY WINDING MEANS ON SAID CORE SURROUNDING SAID PORTION OF SAID FIRST LOOP PATH AND BEING LINKED BY THE PRIMARY FLUX IN SAID PORTION FOR INDUCING VOLTAGE IN SAID SECONDARY WINDING MEANS, A PAIR OF OUTPUT TERMINALS FOR CONNECTION TO THE LOAD, CIRCUIT MEANS FOR CONNECTING SAID PRIMARY WINDING MEANS, SAID EXTENSION AND SAID SECONDARY WINDING MEANS IN CIRCUIT IN SERIES BETWEEN SAID PAIR OF OUTPUT TERMINALS WITH SAID SECONDARY WINDING MEANS AND SAID EXTENSION BEING IN VOLTAGE OPPOSING RELATIONSHIP, AND D.C. CONTROL WINDING MEANS ON SAID CORE FOR SHIFTING SAID PRIMARY FLUX IN SAID NORMAL CONTINUOUS RANGE FROM SAID PORTION OF SAID FIRST LOOP PATH TO SAID AIR GAP MAGNETIC SHUNT PATH BYPASSING SAID CORE PORTION FOR DIVERTING SAID PRIMARY FLUX AWAY FROM SAID SECONDARY WINDING MEANS FOR REDUCING THE AMOUNT OF PRIMARY FLUX LINKING SAID SECONDARY WINDING MEANS AS THE DIRECT CURRENT IN SAID D.C. WINDING MEANS IS INCREASED WITHIN SAID NORMAL CONTINUOUS RANGE FOR REDUCING THE EFFECTIVE AMOUNT OF VOLTAGE OPPOSITION BETWEEN SAID SECONDARY WINDING MEANS AND SAID EXTENSION.
