Phase synchronization of alternating voltages

Claim 1

A CIRCUIT ARRANGEMENT FOR THE SYNCHRONIZING OF THE PHASE OF A FIRST AND OF A SECOND ALTERNATING VOLTAGE, COMPRISING MEANS FOR THE GENERATION OF A FIRST ALTERNATING VOLTAGE, MEANS FOR THE TRANSFORMATION OF SAID FIRST ALTERNATING VOLTAGE INTO A FIRST SQUARE-WAVE VOLTAGE, A SERIES CIRCUIT OF BISTABLE MULTIVIBRATORS, THE OUTPUT OF SAID TRANSFORMATION MEANS BEING CONNECTED TO THE INPUT OF THE FIRST MULTIVIBRATOR OF SAID SERIES CIRCUIT IN WHICH WITHIN SAID SERIES CIRCUIT, THE FIRST OUTPUT OF A MULTIVIBRATOR IS OPERATIVELY CONNECTED WITH THE FIRST AND SECOND PARALLEL-CONNECTED INPUT OF THE SUBSEQUENT MULTIVIBRATOR, THE FIRST OUTPUT OF THE LAST MULTIVIBRATOR SUPPLYING THE FIRST ALTERNATING VOLTAGE TO BE ADJUSTED IN PHASE, A GATE WHOSE OUTPUT IS CONNECTED WITH THE THIRD INPUTS OF SAID BISTABLE MULTIVIBRATORS OTHER THAN THAT OF THE LAST IN SUCH SERIES CIRCUIT AND WHOSE SECOND INPUT IS OPERATIVELY CONNECTED WITH AN OUTPUT OF SAID LAST MULTIVIBRATOR IN SUCH SERIES CIRCUIT, MEANS FOR THE GENERATION OF A SECOND ALTERNATING VOLTAGE AND FOR THE DERIVATION THEREFROM OF A SECOND SQUARE-WAVE VOLTAGE OF A FREQUENCY GREATER THAN THAT OF SAID FIRST SQUARE-WAVE VOLTAGE, MEANS FOR DERIVING A SETTING COMMAND PULSE FROM SAID SECOND SQUARE-WAVE VOLTAGE, AND MEANS FOR SUPPLYING SUCH SETTING COMMAND PULSE TO THE FIRST INPUT OF SAID GATE.
