Blanking circuit for ring counter and including gating circuits at the outputs thereof

Claim 1

A COUNTER HAVING A CONTROLLABLE OUTPUT CIRCUIT THE COMBINATION OF WHICH COMPRISES, A SOURCE OF TIMING PULSES, MEANS CONNECTED FOR COUNTING THE PULSES FROM SAID TIMING PULSE SOURCE AND INCLUDING A PLURALITY OF OUTPUT CIRCUITS FOR DEVELOPING A CORRESPONDING OUTPUT SIGNAL, SWITCHING MEANS FOR EACH OUTPUT CIRCUIT INCLUDING INPUT, OUTPUT, AND CONTROL CIRCUITS AND CHARACTERIZED AS NORMALLY BEING ARRANGED IN A HIGH IMPEDANCE CONDITION BETWEEN THE INPUT AND OUTPUT CIRCUITS THEREOF AND CONNECTED TO BE RESPONSIVE TO A SIGNAL APPLIED AT THE CONTROL CIRCUIT THEREOF BY THE CORRESPONDING OUTPUT CIRCUIT OF SAID TIMING PULSE SOURCE OF SWITCHING INTO A LOW IMPEDANCE CONDITION BETWEEN SAID INPUT AND OUTPUT CIRCUITS, MEANS FOR DEVELOPING A PRESELECTED ELECTRICAL SIGNAL, SECOND SWITCHING MEANS HAVING A CONTROL CIRCUIT, AN OUTPUT CIRCUIT COUPLED IN COMMON TO THE INPUT CIRCUITS OF EACH OF SAID FIRST SWITCHING MEANS AND AN INPUT CIRCUIT COUPLED TO THE PRESELECTED SIGNAL MEANS, SAID SECOND SWITCHING MEANS BEING NORMALLY ARRANGED IN A HIGH IMPEDANCE CONDITION ACROSS THE INPUT AND OUTOUT CIRCUITS THEREOF AND RESPONSIVE TO A SIGNAL APPLIED AT THE CONTROL CIRCUIT THEREOF FOR SWITCHING INTO A LOW IMPEDANCE CONDITION AND THEREBY APPLYING SAID PRESELECTED SIGNAL TO THE INPUT CIRCUITS OF SAID FIRST SWITCHING MEANS, A SOURCE OF SYNCHRONIZING SIGNALS, AND A DELAY CIRCUIT CONNECTED TO BE RESPONSIVE TO THE SIGNALS FROM SAID SYNCHRONIZING SIGNAL SOURCE OF APPLYING A SIGNAL TO THE CONTROL CIRCUIT OF SAID SECOND SWITCHING MEANS.
