Electronic switching network

Claim 1

A COMMUNICATION SWITCHING NETWORK COMPRISISNG A PLURALITY OF BISTABLE BREAKDOWN DEVICES SERIES-CONNECTED BY LINKS IN STAGES TO PROVIDE A PLURALITY OF TRANSMISSION PATHS, EACH DEVICE HAVING AT LEAST A FIRST-POLARITY AND A SECOND-POLARITY ELECTRODE, WITH (A) A BRANCHING SET OF SAID DEVICES HAVING FIRST-POLARITY ELECTRODES CONNECTED IN COMMON TO ONE LINK OF A FIRST GROUP AND SECOND-POLARITY ELECTRODES CONNECTED TO SEPARATE LINKS OF A SECOND GROUP; (D) A RESISTANCE-CAPACITANCE PASSIVE LINK MARKERS INDIVIDUALLY CONNECTING EACH SECOND-GROUP LINK TO A BIAS SOURCE, WHICH NORMALLY BIASES THE LINKS TO THE POTENTIAL OF THE SOURCE; (C) MEANS CONNECTING AN END-MARKING POTENTIAL SOURCE VIA A CIRCUIT INCLUDING RESISTANCE TO SAID ONE FIRSTGROUP LINK TO CAUSR ONE DIVICE OF SAID SET TO BREAK DOWN TO ITS LOW IMPEDANCE STATE, THEREBY BRINGING SAID ONE FIRST-GROUP LINK TO SUBSTANTIALLY THE POTENTIAL OF THE SECOND-GROUP BIAS SOURCE, WHICH PREVENTS BREAK DOWN OF OTHER DEVICES OF SAID SET; SAID MEANS BEING THEN EFFECTIVE TO CAUSE THE CAPACITANCE OF THE SECOND-GROUP LINK MARKERS TO CHANGE FROM SAID ENDMARKING SOURCE TO CHANGE THE POTENTIAL OF THE LINKS AT BOTH SIDES OF SAID ONE DEVICE; (D) SAID MEANS BEING EFFECTIVE TO CAUSE THE CHARGING OF THE SECOND-GROUP LINK MARKER TO CONTINUE, UPON THE NON-COMPLETION OF A CONNECTION FROM THE SECONDGROUP LINK, UNTIL THE POTENTIAL AT SAID ONE FIRST-GROUP LINK CAUSES ANOTHER DEVICE OF SAID SET TO BREAK DOWN, THEREBY AGAIN BRINGING THE FIRST-GROUP LINK TO SUBSTANTIALLY THE POTENTIAL OF THE SECOND-GROUP BIAS SOURCE, WHICH REVERSE BIASES SAID ONE DEVICE AND THEREBY RESTORES IT TO THE HIGH-IMPEDANCE STATE, AND ALSO PREVENTS BREAK DOWN OF OTHER DEVICES OF SAID SET.
