Temperature compensated magnetic oscillator

Claim 1

IN A SATURABLE CORE MAGNETIC OSCILLATOR FOR USE IN VARIABLE AMBIENT CONDITIONS, SAID OSCILLATOR COMPRISING A SATURABLE TRANSFORMER INCLUDING A CORE HAVING A GENERALLY RECTANGULAR HYSTERESIS CHARACTERISTIC, FIRST AND SECOND MAIN WINDINGS AND CONTROL MEANS COMPRISING AT LEAST ONE AUXILIARY WINDING DISPOSED ON SAID CORE, A SOURCE OF VOLTAGE, FIRST AND SECOND SWITCHES EACH HAVING AN INPUT CIRCUIT AND AN OUTPUT CIRCUIT, THE OUTPUT CIRCUITS BEING CONNECTED BETWEEN SAID FIRST AND SECOND MAIN TRANSFORMER WINDINGS RESPECTIVELY AND THE SOURCE OF VOLTAGE FOR CONDUCTING CURRENT THROUGH SAID RESPECTIVE MAIN WINDINGS TO DRIVE THE TRANSFORMER CORE TO THE CONDITION OF POSITIVE AND NEGATIVE SATURATION RESPECTIVELY, THE INPUT CIRCUITS OF SAID SWITCHES BEING COUPLED TO SAID SECOND AND FIRST MAIN TRANSFORMER WINDINGS RESPECTIVELY SO THAT CONDUCTION TAKES PLACE IN SAID SWITCHES ALTERNATELY IN RESPONSE TO ACHIEVING THE CONDITION OF POSITIVE AND NEGATIVE SATURATION AND WITH A REGULAR FREQUENCY OF OSCILLATION; MEANS FOR STABILIZING THE FREQUENCY OF SAID OSCILLATOR UNDER VARYING TEMPERATURE CONDITIONS, SAID MEANS COMPRISING TEMPERATURE RESPONSIVE MEANS IN CIRCUIT WITH SAID CONTROL MEANS FOR LOADING SAID TRANSFORMER INCREASINGLY UPON INCREASE IN TEMPERATURE THEREBY TO COMPENSATE FOR THE REDUCTION IN INHERENT SATURATION POINT OF SAID CORE WHICH OCCURS AT SAID INCREASED TEMPERATURE AND THUS TEND TO MAINTAIN A PRECISE FREQUENCY OF OSCILLATION UPON INCREASE IN AMBIENT TEMPERATURE.
