Voltage comparison and gating circuit

Claim 1

A COMPARISON CIRCUIT COMPRISING: (1) FIRST, SECOND, THIRD, FOURTH AND FIFTH ELECTRONIC AMPLIFYING ELEMENTS EACH HAVING AN INPUT ELECTRODE AND FIRST AND SECOND CONDUCTION ELECTRODES, (2) THE FIRST ELECTRODES OF SAID FIRST AND SECOND ELEMENTS BEING CONNECTED TOGETHER AND TO A COMMON CURRENT SOURCE, (3) THE INPUT ELECTRODE OF SAID FIRST ELEMENT BEING COUPLED TO A SOURCE OF REFERENCE VOLTAGE, (4) THE INPUT ELECTRODE OF SAID SECOND ELEMENT BEING COUPLED TO A SIGNAL VOLTAGE TO BE COMPARED WITH SAID REFERENCE VOLTAGE, (5) THE SECOND CONDUCTION ELECTRODES OF SAID FIRST AND SECOND ELEMENTS BEING CONNECTED TO THE INPUT ELECTRODES OF SAID THIRD AND FOURTH ELEMENTS, RESPECTIVELY, AND THROUGH A COMMON IMPEDANCE TO A FIRST COMMON VOLTAGE SOURCE, (6) THE FIRST CONDUCTION ELECTRODES OF SAID THIRD AND FOURTH ELEMENTS BEING CONNECTED TOGETHER AND TO A SECOND COMMON VOLTAGE SOURCE, (7) SAID FIFTH ELEMENT HAVING ITS FIRST CONDUCTION ELECTRODE CONNECTED TO THE SECOND CONDUCTION ELECTRODE OF SAID FOURTH ELEMENT, (8) THE INPUT ELECTRODE OF SAID FIFTH ELEMENT BEING CONNECTED TO A SOURCE OF CLOCK PULSES, AND (9) TRANSFORMER MEANS HAVING A PRIMARY AND A SECONDARY WINDING, (10) SAID PRIMARY WINDING HAVING ONE TERMINAL CONNECTED TO THE SECOND CONDUCTION ELECTRODE OF SAID FIFTH ELEMENT AND ANOTHER TERMINAL OF SAID PRIMARY WINDING BEING CONNECTED TO SAID FIRST COMMON VOLTAGE SOURCE AND TO THE SECOND CONDUCTION ELECTRODE OF SAID THIRD ELEMENT WHEREBY SAID SECONDARY WINDING PROVIDES CLOCK PULSES ONLY WHEN SAID SIGNAL VOLTAGE EXCEEDS SAID REFERENCE VOLTAGE.
