Asynchronous pulse multiplexing

Claim 1

IN A SYSTEM FOR ASYNCHRONOUSLY MULTIPLEXING INFORMATION BEARING PULSE TRAINS, TWO PULSE TRANSMITTERS EACH OF WHICH GENERATES AN INFORMATION BEARING PULSE TRAIN WHICH IS INDEPENDENT OF THE PULSE TRAIN GENERATED BY THE OTHER TRANSMITTER IN BOTH PHASE AND FREQUENCY RELATIONSHIP BUT WHOSE PULSES HAVE SUBSTANTIALLY THE SAME PULSE WIDTH AS THE PULSES GENERATED BY THE OTHER TRANSMITTER WITH THE AMPLITUDE OF THE PULSES GENERATED BY A FIRST OF THE PULSE TRANSMITTERS BEING ONE-HALF THE AMPLITUDE OF THE PULSES GENERATED BY THE SECOND OF THE PULSE TRANSMITTERS, MEANS TO ADD THE PULSE TRAINS SO THAT AN OVERLAPPING SUM OF THE PULSE TRAINS IS PRODUCED, MEANS TO TRANSMITT THE OVERLAPPING SUM SIGNAL, A RECEIVE TO RECEIVE THE TRANSMITTED SIGNAL, MEANS AT SAID RECEIVER TO GENERATE A PULSE AT A FIRST OUTPUT TERMINAL WHEN THE RECEIVED SIGNAL IS GREATER THAN ONE-HALF THE AMPLITUDE OF A PULSE RECEIVED FROM THE FIRST OF THE PULSE TRANSMITTERS BUT LESS THAN THE AMPLITUDE OF A PULSE RECEIVED FROM THE SECOND OF THE PULSE TRANSMITTERS, MEANS TO GENERATE AN OUTPUT PULSE AT A SECOND OUTPUT TERMINAL WHEN THE RECEIVED SIGNAL IS GREATER IN AMPLITUDE THAN THE AMPLITUDE OF A PULSE RECEIVED FROM THE FIRST OF THE PULSE TRANSMITTERS BUT LESS THAN THE AMPLITUDE OF A PULSE RECEIVED FROM THE SECOND OF THE PULSE TRANSMITTERS, AND MEANS TO GENERATE AN OUTPUT PULSE AT SAID FIRST AND SAID SECOND OUTPUT TERMINALS WHEN THE RECEIVED SIGNAL IS GREATER IN AMPLITUDE THAN THE AMPLITUDE OF A PULSE RECEIVED FROM THE SECOND OF THE PULSE TRANSMITTERS.
