Half frequency power supply for vibrating machines

Claim 1

A FREQUENCY DIVIDING CIRCUIT COMPRISING; A SINGLE PHASE SOURCE OF ALTERNATING CURRENT; A PAIR OF GATABLE DISCHARGE DEVICES EACH HAVING AN ANODE, A CATHODE, AND A GATING ELECTRODE, SAID CATHODES BEING ELECTRICALLY CONNECTED COMMONLY, AN INPUT TRANSFORMER HAVING A PRIMARY WINDING ELECTRICALLY CONNECTED ACROSS SAID ALTERNATING CURRENT SOURCE AND HAVING A CENTER-TAPPED SECONDARY WINDING, EACH OF THE EXTREME OPPOSITE TERMINALS OF WHICH ARE ELECTRICALLY CONNECTED TO EACH OF SAID ANODES OF SAID DISCHARGE DEVICES; A LOAD IMPEDANCE ELECTRICALLY CONNECTED FROM THE CENTER-TAP OF SAID SECONDARY WINDING TO THE COMMON CATHODE CONNECTION OF SAID DISCHARGE DEVICES; A FIRST PAIR OF RESISTIVE ELEMENTS ONE END OF EACH BEING ELECTRICALLY CONNECTED TO THE GATING ELECTRODES OF SAID RESPECTIVE DISCHARGE DEVICES; A SECOND PAIR OF RESITIVE ELEMENTS ONE END OF EACH BEING ELECTRICALLY CONNECTED TO THE OTHER END OF EACH OF SAID RESPECTIVE FIRST PAIR OF RESISTIVE ELEMENTS AND THE OTHER END OF EACH OF SAID SECOND PAIRS BEING ELECTRICALLY CONNECTED COMMONLY; A SOURCE OF D.C. POTENTIAL, THE POSITIVE POLE OF WHICH IS ELECTRICALLY CONNECTED TO SAID COMMON CATHODE TERMINAL, AND THE NEGATIVE POLE OF WHICH IS ELECTRICALLY CONNECTED TO SAID OTHER END OF SAID COMMONLY CONNECTED SECOND PAIR OF RESISTIVE ELEMENTS; A FIRST PAIR OF MAGNETIC AMPLIFIERS EACH HAVING AN INPUT ELECTRICALLY CONNECTED TO THE SOURCE OF ALTERNATING CURRENT AND EACH HAVING AN OUTPUT ELECTRICALLY CONNECTED ACROSS A RESPECTIVE ONE OF SAID FIRST PAIR OF RESISTIVE ELEMENTS FOR PROVIDING A VOLTAGE THEREACROSS TO THE GATE SAID PAIR OF DISCHARGE DEVICES AT ANY POINT DURING EVERY SUCCESSIVE HALF CYCLE WHEN SAID RESPECTIVE DISCHARGE DEVICES HAVE POSITIVE-GOING PULSES APPLIED TO THEIR ANODES; A SECOND PAIR OF MAGNETIC AMPLIFIERS EACH HAVING AN INPUT ELECTRICALLY CONNECTED TO THE SOURCE OF ALTERNATING CURRENT AND EACH COMPRISING A FEEDBACK MEANS ELECTRICALLY CONNECTED TO ITS RESPECTIVE INPUTS AND HAVING AN OUTPUT EACH OF WHICH IS ELECTRICALLY CONNECTED ACROSS A RESPECTIVE ONE OF SAID SECOND PAIR OF RESISTIVE ELEMENTS FOR PROVIDING A VOLTAGE THEREACROSS IN OPPOSITION TO SAID VOLTAGE PROVIDED BY SAID FIRST PAIR OF MAGNETIC AMPLIFIERS TO CANCEL SAID VOLTAGES ON EVERY ALTEARNATE CYCLE OF SAID SOURCE AS GOVERNED BY SAID FEEDBACK MEANS, THEREBY PROVIDING OUTPUT ACROSS SAID LOAD IMPEDANCE HAVING A FREQUENCY EQUAL TO ONE-HALF THE FREQUENCY OF SAID ALTERNATING CURRENT SOURCE.
