Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
107 words
A VARIABLE FREQUENCY CONTROL CIRCUIT COMPRISING A SATURABLE REACTOR HAVING POSITIVE AND NEGATIVE SATURATION MAGNETIZATION CONDITIONS, A TUNNEL DIODE AND A SOURCE OF DIRECT CURRENT ELECTRIC POTENTIAL, SAID SATURABLE REACTOR AND SAID SOURCE OF DIRECT CURRENT ELECTRIC POTENTIAL BEING CONNECTED IN SERIES CIRCUIT RELATIONSHIP ACROSS SAID TUNNEL DIODE, MEANS TO PROVIDE A DIRECT CURRENT CONTROL SIGNAL OF VARYING MAGNITUDE TO THE CIRCUIT THUS COMPRISED FOR CAUSING THE CURRENT EXCURSIONS OF THE TUNNEL DIODE TO DRIVE THE SATURABLE REACTOR THROUGH DIFFERENT CHARACTERISTIC MINOR HYSTERESIS LOOPS FOR DIFFERENT FREQUENCIES OF OPERATION, AND MEANS FOR OPERATIVELY COUPLING A LOAD TO SAID CIRCUIT FOR DRIVING A VARIABLE FREQUENCY CONTROL SIGNAL THEREFROM.
