Apparatus for measuring the distance to an open circuit in a cable pair including means for storing a charge commensurate with such distance

Claim 1

AN OPEN CABLE LOCATOR COMPRISING TERMINAL MEANS FOR ESTABLISHING A CONNECTION WITH CONDUCTORS TO BE TESTED VOLTAGE MEANS CONNECTED TO SAID TERMINAL MEANS FOR APPLYING A PREDETERMINED VOLTAGE ACROSS CONDUCTORS UNDER TEST TO CHARGE THE CONDUCTORS UNDER TEST WITH THE POTENTIAL CHARGE, THE CONDUCTORS STORING A CHARGE COMMENSURATE WITH THE UNINTERRUPTED LINEAR DISTANCE THEREOF, STORAGE MEANS FOR STORING A POTENTIAL CHARGE, MEANS INTERCONNECTING SAID TERMINAL MEANS AND SAID STORAGE MEANS FOR TRANSFERRING POTENTIAL CHARGE ACROSS THE CONDUCTORS UNDER TEST TO SAID STORAGE MEANS, RECORDING MEANS HAVING A CALIBRATED SCALE TO INDICATE LINEAR DISTANCE AND RESPONSIVE TO A POTENTIAL CHARGE FOR INDICATING THE MAGNITUDE OF THE POTENTIAL CHARGE IN LINEAR DISTANCE, AND MEANS INTERCONNECTING SAID STORAGE MEANS WITH SAID RECORDING MEANS AND RESPONSIVE TO THE POTENTIAL CHARGE ON SAID STORAGE MEANS FOR OPERATING SAID RECORDING MEANS, SAID RECORDING MEANS BEING OPERATED TO GIVE A DIRECT READING OF THE UNINTERRUPTED LINEAR DISTANCE OF THE CONDUCTORS UNDER TEST.
