Transistor gate biased by signal being gated

Claim 1

IN A SWITCHING SYSTEM WHICH INCLUDES: A FIRST COMPONENT HAVING A N OUTPUT CIRCUIT AND AT LEAST ONE FURTHER COMPONENT HAVING AN INPUT CIRCUIT, SAID OUTPUT CIRCUIT INCLUDING AN IMPEDANCE ELEMENT CONNECTED TO A SOURCE DIRECT CURRENT EXCITING POTENTIAL AND ACROSS WHICH OUTPUT SIGNALS APPEAR, SAID INPUT CIRCUIT INCLUDING AN IMPEDANCE ELEMENT CONNECYED TO A POINT OF REFERENE POTENTIAL, A SWITCHING COMPONENT FOR SELECTIVELY INTRODUCING SAID OUTPUT SIGNALS FROM SAID OUTPUT CIRCUIT OF SAID FIRST COMPONENT TO SAID INPEDANCE ELEMENT IN SAID INPUT CIRCUIT OF SAID FURTHER COMPONENT INCLUDING IN COMBINATION: AN ELECTRONIC DISCHARGE DEVICE HAVING A FIST ELECTRODE, A SECOND ELECTRODE AND A THIRD ELECTRODE; INPUT TERMINAL MEANS FOR RECEIVING SAID OUTPUT SIGNALS FROM SAID FIRST COMPONENT; A DIERCT CURRENT CIRCUIT CONNECTION FROM SAID INPUT TERMINAL MENAS TO SAID FIRST ELECTRODE OF SAID ELECRONIC DISCHARGE DEVICE TO SUPPLY EXCITING POWER TO SAID FIRST ELECTRODE FROM SAID OUTPUT SIGNALS; SECOND CIRCUIT MEANS INCLUDING FIRST AND SECOND SERIES-CONNECTED RESISTANCE MEANS CONNECTED TO SID INPUT TERMINAL MEANS AND TO SIAD SECOND ELECTRODE OF SAID ELECTRONIC DISCHARGE DEVICE OUTPUT TERMINAL MEANS CONNECTED TO SID THIRD ELECTRODE OF SIAD ELECTONIC DISCHARGE DEVICE FOR RECEIVING SAID SIGNALS FOR APPLICATION TO SAID IMPEDANCE ELEMENT IN SAID INPUT CIRCUIT OF SAID FURTHER COMPONENT; AND MEANS FOR SELEC TIVELY ESTABLISHING THE COMMON JUNCTION OF SAID FIRST AND SECOND RESISTANCE MEANS AT DIFFERENT POTENTIAL LEVELS TO CONTROL THE PASSAGE OF SAID SIGNALS THROUGH SAID ELECTONIC DISCHARGE DEVICE.
