High-low voltage sensitive signaling circuit utilizing semiconductors

Claim 1

A VOLTAGE SENSITIVE CIRCUIT HAVING INPUT TERMINALS AND INCLUDING FIRST INPUT VOLTAGE PROPORTIONING MEANS, MEANS FOR CONNECTING SAID FIRST INPUT VOLTAGE PROPORTIONING MEANS BETWEEN SAID TERMINALS, A CONSTANT VOLTAGE SOURCE, VARIABLE CONDUCTING MEANS HAVING AN INPUT SECTION AND AN OUTPUT SECTION, MEANS FOR CONNECTING SAID INPUT SECTION OF SAID VARIABLE CONDUCTING MEANS BETWEEN ONE SIDE OF SAID CONSTANT VOLTAGE SOURCE AND SAID FIRST INPUT VOLTAGE PROPORTIONING MEANS, MEANS FOR CONNECTING THE OTHER SIDE OF SAID CONSTANT VOLTAGE SOURCE TO ONE OF SAID INPUT TERMINALS, A CURRENT ENERGIZED SWITCH SERIALLY CONNECTED WITH THE OUTPUT SECTION OF SAID VARIABLE CONDUCTING MEANS, SECOND INPUT VOLTAGE PROPORTIONING MEANS, MEANS FOR CONNECTING SAID SECOND INPUT VOLTAGE PROPORTIONING MEANS BETWEEN SAID TERMINALS, SECOND INITIATOR MEANS, MEANS FOR CONNECTING SAID SECOND INITIATOR MEANS BETWEEN SAID CONSTANT VOLTAGE SOURCE AND SAID SECOND INPUT VOLTAGE PROPORTIONING MEANS TO COMPARE THE POTENTIAL OF SAID CONSTANT VOLTAGE SOURCE TO THE VOLTAGE OF SAID SECOND INPUT VOLTAGE PROPORTIONING MEANS AND TO RENDER SAID VARIABLE CONDUCTING MEANS NONCONDUCTING IF THE INPUT VOLTAGE IS GREATER THAN A PREDETERMINED MAXIMUM VALUE.
