Bipolar signal receiver with input and output non-linear limiting means with interconnecting feedback

Claim 1

A SIGNAL RECEIVER FOR BIPOLAR SIGNALS, SAID SIGNAL RECEIVER COMPRISING AMPLIFIER MEANS INCLUDING AT LEAST ONE INPUT CIRCUIT AND ONE OUTPUT CIRCUIT AND A SIGNAL-LIMITING MEANS SAID SIGNAL-LIMITING MEANS COMPRISING A FIRST AND A SECOND CURRENT-CONTROLLING MEANS, THE FIRST ONE OF SAID CURRENT-CONTROLLING MEANS BEING CONNECTED TO SAID OUTPUT CIRCUIT AND INCLUDING A FIRST AND A SECOND NON-LINEAR CONDUCTIVE ELEMENT OPPOSITELY CONNECTED IN SERIES ACROSS SAID OUTPUT CIRCUIT, THE SECOND OF SAID CURRENT-CONTROLLING MEANS BEING CONNECTED TO SAID INPUT CIRCUIT AND INCLUDING A THIRD NON-LINEAR CONDUCTIVE ELEMENT AND AN IMPEDANCE MEANS CONNECTED IN CIRCUIT WITH SAID THIRD NONLINEAR CONDUCTIVE ELEMENT, A BIASING POTENTIAL OBTAINED ACROSS SAID IMPEDANCE MEANS BEING CONNECTED TO SAID THIRD NON-LINEAR CONDUCTIVE ELEMENT, SAID POTENTIAL HAVING A VALUE CAUSING SAID THIRD NON-LINEAR CONDUCTIVE ELEMENT TO CONTROL AN INPUT SIGNAL FED TO SAID AMPLIFIER MEANS WHEN SAID INPUT SIGNAL VOLTAGE IS BELOW A FIRST SIGNAL LEVEL, SAID FIRST AND SECOND NON-LINEAR CONDUCTIVE ELEMENTS BEING CONNECTED TO SAID IMPEDANCE MEANS TO BE BLOCKED BY A POTENTIAL DUE TO A DIRECT CURRENT PASSING THROUGH SAID IMPEDANCE MEANS, AND A DIRECT CURRENT CONNECTION BETWEEN SAID OUTPUT CIRCUIT AND THE CONNECTING POINT OF SAID THIRD NON-LINEAR CONDUCTIVE ELEMENT AND SAID IMPEDANCE MEANS TO OVERCOME THE BIAS POTENTIAL ON SAID THIRD NON-LINEAR CONDUCTIVE ELEMENT WHEN THE INPUT SIGNAL VOLTAGE REACHES A SECOND SIGNAL LEVEL.
