Independent Claim
169 words
A SIGNAL-PRODUCING CIRCUIT COMPRISING: A D.C. VOLTAGE SOURCE, A PAIR OF INPUT TERMINALS FOR RECEIVING INPUT SIGNALS, A TIME DELAY NETWORK OPERATIVELY CONNECTED TO EACH OF SAID INPUT TERMINALS AND SAID VOLTAGE SOURCE FOR PASSING INPUT SIGNALS OF A PREDETERMINED DURATION SUPPLIED TO SAID INPUT TERMINALS, A MULTIVIBRATOR HAVING INPUTS CONNECTED TO SAID TIME DELAY NETWORKS AND SAID D.C. VOLTAGE SOURCE AND HAVING A SWITCHING STATE CORRESPONDING TO THE APPEARANCE OF A SIGNAL AT ONE OF SAID INPUTS AND A SWITCHING STATE CORRESPONDING TO THE APPEARANCE OF A SIGNAL AT THE OTHER OF SAID INPUTS, A PAIR OF OUTPUT CIRCUIT MEANS OPERATIVELY CONENCTED TO SAID D.C. VOLTAGE SOURCE AND TO SAID MULTIVIBRATOR AND RESPONSIVE TO THE SWITCHING STATE OF SAID MULTIVIBRATOR FOR PROVIDING AN OUTPUT SIGNAL AT ONLY ONE OF SAID OUTPUT CIRCUIT MEANS WHEN SAID MULTIVIBRATOR IS MAINTAINED IN ONE OF ITS TWO SWITCHING STATES AND AT ONLY THE OTHER OF SAID OUTPUT CIRCUIT MERANS WHEN SAID MULTIVIBRATOR IS MAINTAINED IN THE OTHER OF ITS TWO SWITCHING STATES.
