Voltage regulator with frequency multiplication detector means

Claim 1

A VOLTAGE REGULATED SYSTEM COMPRISING: MOTOR COMPRISING, IN COMBINATION: TERMINALS; A TRANSFORMER HAVING A PRIMARY WINDING CONNECTED ACROSS SAID OUTPUT TERMINALS AND A SECONDARY WINDING INDUCTIVELY COUPLED TO THE PRIMARY WINDING; A FULL WAVE RECTIFIER HAVING INPUT AND OUTPUT TERMINALS; A BRIDGE NETWORK HAVING DIAGONALLY OPPOSITE INPUT AND OUTPUT TERMINALS, THREE ARMS OF THE BRIDGE CONA FLITER CIRCUIT INCLUDING AN INDUCTANCE COIL AND A CAPACICONSISTING OF A ZENER DIODE HAVING ONE ELECTRODE CONNECTED TO ONE OF THE INPUT TERMINALS OF THE BRIDGE NETWORK; INDUCTIVE IMPEDANCE MEANS COUPLING ONE OF THE OUTPUT TERMINALS OF SAID RECTIFIER TO SAID ONE INPUT TERMINAL OF THE BRIDGE NETWORK, THE OTHER RECTIFIER OUTPUT TERMINAL BEING CONNECTED TO THE OTHER INPUT TERMINAL OF THE BRIDGE NETWORK; CAPACITOR MEANS SHUNTING THE OUTPUT TERMINALS OF SAID RECTIFIER; MEANS INCLUDING AN AMPLIFIER COUPLING SAID FIELD WINDING ACROSS THE OUTPUT TERMINALS OF SAID BRIDGE NET COUPLED ACROSS THE ALTERNATING VOLTAGE SOURCE; A PLURALITY OF FREQUENCY MULTIPLICATION STAGE COUPLING THE SECONDARY WINDINGS OF SAID TRANSFORMER ACROSS THE INPUT OF SAID RECTIFIER, EACH OF SAID FREQUENCY MULTIPLICATION STAGES INCLUDING A FULL WAVE BRIDGE RECTIFIER, A RESISTIVE IMPEDANCE SHUNTING THE SIGNAL INPUT PATH TO SAID BRIDGE RECTIFIER, AND CAPACITANCE MEANS IN SERIES WITH SAID SIGNAL INPUT PATH.
