Claim 1
Independent Claim
239 words
A SYSTEM FOR AMPLIFYING A VARIABLE CONTROL SIGNAL PRIOR TO THE APPLICATION THEREOF TO ONE OF TWO OUTPUT CIRCUITS COMPRISING, A VARIABLE CONTROL SIGNAL SOURCE, A MAGNETIC AMPLIFIER CAMPRISING A FIRST PRIMARY WINDING WOUND ON A FIRST SATURABLE CORE, A SECONDARY PRIMARY WINDING WOUND ON A SECOND SATURABLE CORE, A FIRST SECONDARY WINDING WOUND ON SAID FIRST CORE, A SECOND SECONDARY WINDING WOUND ON SAID SECOND CORE, A TERTIARY WINDING WOUND ON BOTH SAID FIRST AND SECOND CORES, SAID FIRST AND SECOND PRIMARY WINDINGS CONNECTED IN SERIES OPPOSITION TO A SOURCE OF PULSING D.C. VOLTAGE, SAID FIRST AND SECOND SECONDARY WINDINGS CONNECTED IN SERIES-AIDING RELATIONSHIP TO A FIRST OUTPUT CIRCUIT, SAID FIRST AND SECOND SECONDARY WINDINGS CONNECTED TO A SECOND OUTPUT CIRCUIT, MEANS CONNECTING SAID TERTIARY WINDING TO SAID VARIABLE CONTROL SIGNAL SOURCE THROUGH A BLOCKING CAPACITOR IN SUCH A MANNER THAT A DECREASE IN THE MAGNITUDE OF THE VARIABLE CONTROL SIGNAL WILL CAUSE A POSITIVE VOLTAGE TO OCCUR ACROSS SAID FIRST AND SECOND SECONDARY WINDINGS AND AN INCREASE IN THE MAGNITUDE OF THE VARIABLE CONTROL SIGNAL WILL CAUSE A NEGATIVE VOLTAGE TO OCCUR ACROSS SAID FIRST AND SECOND SECONDARY WINDINGS, SAID FIRST OUTPUT CIRCUIT INCLUDING A FIRST RECTIFIER MEANS POLARIZED TO CONDUCT WHEN A POSITIVE VOLTAGE OCCURS ACROSS SAID FIRST AND SECOND SECONDARY WINDINGS, SAID SECOND OUTPUT CIRCUIT INCLUDING A SECOND RECTIFIER MEANS POLARIZED TO CONDUCT WHEN A NEGATIVE VOLTAGE OCCURS ACROSS SAID FIRST AND SECOND SECONDARY WINDINGS.
