Total Claims: 2
Claim 1
Independent Claim
128 words
A PUSH-PULL FULL-WAVE MAGNETIC AMPLIFIER INCLUDING TWO PAIRS OF SATURABLE CORES EACH HAVING AN OUTPUT WINDING AND A SOURCE OF SWITCHING PULSES OF ALTERNATELY OPPOSITE POLARITY CHARACTERIZED IN THAT THE CORES OF EACH PAIR ARE INDUCTIVELY COUPLED IN PUSH-PULL RELATION BY AN INPUT-SIGNAL WINDING COMMON TO ALL CORES, AND THAT A COUPLING RESISTANCE MEANS IS CONNECTED BETWEEN THE OUTPUT WINDINGS OF ONE OF THE CORES OF EACH OF SAID PAIRS TO PROVIDE A SERIES-CIRCUIT ACROSS SAID SOURCE FOR ALTERNATE RESETTING OF SAID ONE CORE OF EACH OF THE TWO PAIRS BY CURRENT FROM SAID SOURCE, THE OTHER CORE OF EACH OF THE TWO PAIRS BEING RESET BY CURRENT INDUCED IN SAID INPUT-SIGNAL WINDING COMMON TO ALL CORES IN CONSEQUENCE OF THE CURRENT-FLOW THROUGH SAID SERIES-CIRCUIT FROM SAID SOURCE.
