Signal receiving and indicating system having receiver controlled indicator operatedintermittently during signal reception to prevent regeneration

Claim 1

IN A SIGNAL RECEIVING SYSTEM, A RECEIVER FOR RECEIVING SIGNALS FROM A REMOTE SOURCE, A SIGNALLING INDICATOR LOCATED PROXIMATE SAID RECEIVER FOR GENERATING A PERCEPTIBLE INDICATION AND ALSO GENERATING CONCURRENTLY WITH SAID PERCEPTIBLE INDICATION AN INTERFERENCE SIGNAL RECEIVABLE BY SAID RECEIVER, A FIRST CIRCUIT, FIRST MEANS CONNECTED TO SAID FIRST CIRCUIT AND SAID RECEIVER FOR ENERGIZING SAID FIRST CIRCUIT IN RESPONSE TO THE RECEPTION BY SAID RECEIVER OF SAID SIGNAL FROM SAID REMOTE SOURCE AND DEENERGIZING SAID CIRCUIT IN THE ABSENCE OF AN INPUT SIGNAL TO SAID RECEIVER, SAID FIRST CIRCUIT INCLUDING A RELAY HAVING A WINDING AND NORMALLY CLOSED CONTACTS SERIALLY INCLUDED IN SAID FIRST CIRCUIT TO EFFECT INTERMITTING OPERATION OF SAID RELAY DURING THE RECEPTION OF SAID SIGNAL FROM SAID REMOTE SOURCE, SAID RELAY ALSO HAVING NORMALLY OPEN CONTACTS WHICH ARE CLOSED BY THE ACTUATION OF SAID RELAY, AND AN ENERGIZING CIRCUIT FOR SAID INDICATOR INCLUDING SAID NORMALLY OPEN CONTACTS WHEREBY SAID NORMALLY OPEN CONTACTS EFFECT ONLY INTERMITTENT ENERGIZATION OF THE INDICATOR DURING THE RECEPTION OF SAID RECEIVED SIGNAL FROM SAID REMOTE SOURCE TO THEREBY PREVENT THE GENERATION OF CONTINUOUS INTERFERENCE SIGNALS BY SAID INDICATION AND CONTINUOUS ENERGIZATION OF SAID FIRST CIRCUIT BY SAID FIRST MEANS.
