Claim 1
Independent Claim
157 words
A CIRCUIT FOR CONTROLLING THE OPERATION OF A WAVE GENERATOR IN SYNCHRONISM WITH THE POWERING MEANS FOR A LOAD CIRCUIT DRIVEN IN RESPONSE TO THE OPERATION OF THE WAVE GENERATOR, COMPRISING A SIGNAL RESPONSIVE DEVICE HAVING CONDUCTING AND NONCONDUCTING STATES OF OPERATION COUPLED TO SAID WAVE GENERATOR AND OPERATIVE WHEN CONDUCTING TO INHIBIT THE OPERATION OF THE GENERATOR AND OPERATIVE WHEN NONCONDUCTING TO PERMIT THE OPERATION OF THE GENERATOR, MEANS FOR COUPLING AN INPUT SIGNAL RESIDING AT EITHER OF TWO LEVELS TO SAID DEVICE SO THAT SAID DEVICE IS NONCONDUCTING IN RESPONSE TO THE SIGNAL AT THE FIRST LEVEL AND CONDUCTING IN RESPONSE TO THE SIGNAL AT THE SECOND LEVEL, AND MEANS COUPLED TO SAID DEVICE AND TO THE POWERING MEANS FOR DEVELOPING A SIGNAL TO SYNCHRONIZE THE OPERATION OF SAID GENERATOR WITH THE POWERING OF SAID LOAD CIRCUIT BY PERIODICALLY INHIBITING THE OPERATION OF SAID WAVE GENERATOR WHEN THE INPUT SIGNAL IS AT THE FIRST LEVEL.
