Pulse gate circuit inhibiting transmission when blocking signal coincides with inputsignal

Claim 1

A PULSE GATING CIRCUIT OF THE TYPE WHICH IS INTERPOSED BETWEEN A SOURCE OF DATA PULSE SIGNALS AND PULSE SIGNAL UTILIZATION APPARATUS FOR SELECTIVELY BLOCKING PASSAGE OF UNDESIRED DATA PULSES, COMPRISING: GATE CIRCUIT MEANS HAVING AN INPUT TERMINAL FOR CONNECTION TO SAID SOURCE AND AN OUTPUT TERMINAL FOR CONNECTION TO SAID UTILIZATION APPARATUS, AND HAVING A CONTROL CIRCUIT OPERATIVE TO PERFORM SAID SELECTIVE BLOCKING IN RESPONSE TO AN APPLIED CONTROL SIGNAL; MEANS FOR SUPPLYING SAID CONTROL SIGNAL TO THE CONTROL CIRCUIT IN RESPONSE TO ONE OR MORE EXTERNALY SUPPLIED LOGIC SIGNALS REPRESENTATIVE OF SIGNAL PROCESSING FUNCTIONS IN SAID UTILIZATION APPARATUS; SENSING MEANS RESPONSIVE TO SAID DATA PULSE SIGNALS AND COUPLED TO SAID GATE CIRCUIT MENS INPUT TERMINAL FOR PROVIDING AN AUXILIARY CONTROL EFFECT WHENEVER SAID DATA PULSE SIGNALS FROM THE SOURCE ARE AT ANY LEVEL OTHER THAN A REFERENCE LEVEL CORRESPONDING TO COMPLETE ABSENCE OF DATA PULSES; MEANS INTERCOUPLING SAID SENSING MEANS AND SAID CONTROL SIGNAL SUPPLY MEANS FOR APPLYING A BLOCKING CONTROL SIGNAL TO SAID CONTROL CIRCUIT IN RESPONSE TO THE SIMULTANEOUS PRESENCE OF SAID AUXILIARY CONTROL EFFECT WITH ANY ONE OR MORE OF SAID LOGIC SIGNALS AND FOR MAINTAINING THE APPLICATION OF SAID BLOCKING CONTROL SIGNAL THEREAFTER UNTIL THE SIMULTANEOUS ABSENCE OF SAID AUXILIARY CONTROL EFFECT AND ALL OF SAID LOGIC SIGNALS.
