Comparison voltage measuring circuits using condenser charging and discharging

Claim 1

A VOLTAGE COMPUTER CIRCUIT INCLUDING RESISTANCE NETWORK MEANS TO ESTABLISH A SIGNAL POTENTIAL BETWEEN A REFERENCE POINT AND A SECOND POINT ON SAID NETWORK, A SUBSTANTIALLY CONSTANT POTENTIAL SOURCE OF POLARITY OPPOSITE TO THE SIGNAL POTENTIAL AT SAID REFERENCE POINT, SAID SUBSTANTIALLY CONSTANT POTENTIAL BEING OF MAGNITUDE SUBSTANTIALLY GREATER THAN THE MAGNITUDE OF SAID SIGNAL POTENTIAL AT SAID REFERENCE POINT, AN RC TIME DELAY CIRCUIT CONNECTING SAID REFERENCE POINT AND SAID POTENTIAL SOURCE, SAID RC CIRCUIT INCLUDING A CONDENSER, A BY-PASS CONNECTION SHORT CIRCUITING THE CONDENSER OF SAID RC CIRCUIT TO BASE POTENTIAL, SWITCH MEANS CONNECTING SAID POTENTIAL SOURCE TO SAID REFERENCE POINT WHEN SAID SIGNAL POTENTIAL IS ESTABLISHED AT SAID REFERENCE POINT, AND SUBSTANTIALLY SIMULTANEOUSLY TO OPEN THE SAID BY-PASS SHORT CIRCUIT CONNECTION TO SAID BASE POTENTIAL, SWITCH MEANS ALSO HAVING MEANS TO DISCONNECT THE SAID POTENTIAL SOURCE FROM SAID REFERENCE POINT WHEN THE POTENTIAL AT SAID REFERENCE POINT IS SUBSTANTIALLY THAT AT SAID SECOND POINT AND SUBSTANTIALLY SIMULTANEOUSLY TO CLOSE THE SAID BY-PASS CIRCUIT TO SHUNT THE CONDENSER TO SAID BASE POTENTIAL.
