Apparatus for simultaneously performing switching operations in spatially separated transmitter and receiver units

Claim 1

APPARATUS FOR SIMULTANUOUSLY PERFORMING A SWITCHING OPERATION IN AT LEAST ONE TRANSMITTER UNIT AND RECEIVER UNIT LOCATED SPATIALLY APRT FROM ONE ANOTHER, SAID APPARATUS COMPRISING FOR EACH UNIT AN IMPULSE SENDER, A PROGRAM SENDER AND MEANS FOR SYNCHRONIZING SAID IMPULSE SENDERS, SAID PROGRAM SENDERS BEING DRIVEN BY SAID IMPULSE SENDERS WITH SYNCHRONIZED IMPULSES, EACH OF SAID PROGRAM SENDERS PRODUCING AN IDENTICAL SEQUENCE OF PROGRAM SIGNALS BEING LIMITED IN TIME AND CONSISTING OF IMPULSE COMBINATIONS, EACH OF SAID IMPULSE COMBINATIONS BEING DIFFERENT FROM ALL THE OTHER IMPULSE COMBINATIONS OF ITS SEQUENCE AND HAVING A PREDETERMINED POSITION WITHIN ITS SEQUENCE, MEANS FOR TRANSMITTING SAID SIGNAL SEQUENCE PRODUCED BY THE PROGRAM SENDER FROM THE TRANSMITTER UNIT TO THE RECEIVER UNIT, MEANS PROVIDED IN SAID RECEIVER UNIT FOR COMPARING SAID SIGNAL SEQUENCIES IMPULSES COMBINATION BY IMPULSE COMBINATION AND FOR PRODUCING A CONTROL SIGNAL WHICH INDICATES THE DIRECTION OF ANY DEVIATION IN TIME OF THE SIGNAL SEQUENCE PRODUCED BY THE PROGRAM SENDER OF THE RECEIVER UNIT WITH RESPECT TO THE SIGNAL SEQUENCE PRODUCED BY THE PROGRAM SENDER OF THE TRANSMITTER UNIT, MEANS IN SAID RECEIVER UNIT FOR VARYING THE SPEED OF ITS OWN PROGRAM SENDER IN THE OPPOSITE DIRECTION TO THAT INDICATED BY SAID CONTROL SIGNAL AND MEANS BY WHICH EACH PROGRAM SENDER RELEASES A SWITCHING OPERATION BY ITS OWN UNIT AFTER A PREDETERMINED NUMBER OF PROGRAM STEPS WHOSE NUMBER IS IDENTICAL IN SAID PROGRAM SENDERS.
