Apparatus for measuring the percent change in length of strip material after formation about a cable core

Claim 1

AN APPARATUS FOR MEASURING THE PERCENT CHANGE IN LENGTH OF A MOVING CONTINUOUS STRIP OF MATERIAL RESULTING FROM FORMING THE STRIP ABOUT A CABLE CORE BY MEANS OF A FORMING DEVICE COMPRISING: A FIRST PHOTOELECTRIC DEVICE LOCATED IN ADVANCE OF THE FORMING DEVICE AND INCLUDING A LIGHT SOURCE GENERATING A BEAM AND A RECEIVER ON WHICH THE BEAM PERIODICALLY IMPINGES, A FIRST COUNTER WHEEL POSITIONED INTERMEDIATE THE SOURCE AND THE RECEIVER AND MOVABLE INTO CONTACT WITH THE STRIP, SAID WHEEL INCLUDING A CIRCULAR ARRAY OF OPENINGS WHICH PERIODAICALLY PASS SAID BEAM TO THE RECEIVER AS THE WHEEL ROTATES, SAID BEAM THEREBY GENERATING PULSES AT A RATE PROPORTIONAL TO THE LINEAR RATE OF MOVEMENT OF THE STRIP PRIOR TO THE FORMATION OF THE STRIP ABOUT THE CABLE CORE, A FIRST COUNTER FOR MEASURING THE NUMBER OF PULSES GENERATED BY THE FIRST PHOTOELECTRIC DEVICE, A SECOND PHOTOELECTRIC DEVICE LOCATED BEYOND THE FORMING DEVICE INCLUDING A LIGHT SOURCE FOR GENERATING A BEAM AND A RECEIVER ON WHICH THE BEAM PERIODICALLY IMPINGES, A SECOND COUNTER WHEEL POSITIONED INTERMEDIATE THE SOURCE AND THE RECEIVER AND MOVABLE INTO CONTACT WITH THE STRIP AFTER IT HAS BEEN FORMED ABOUT THE CORE, SAID WHEEL INCLUDING A CIRCULAR ARRAY OF OPENINGS WHICH PERIODICALLY PASS SAID BEAM TO THE RECEIVER AS THE WHEEL ROTATES, SAID BEAM THEREBY GENERATING PULSES AT A RATE PROPORTIONAL TO THE LINEAR RATE OF MOVEMENT OF THE STRIP FORMED ABOUT THE CABLE CORE, A SECOND COUNTER FOR MEASURING THE NUMBER OF PULSES GENERATED BY THE SECOND PHOTOELECTRIC DEVICE, AND MEANS FOR MOVING THE COUNTER WHEELS INTO CONTACT AND OUT OF CONTACT WITH THE STRIP, CIRCUIT MEANS INCLUDING: MEANS FOR OPERATING THE MOVING MEANS TO MOVE THE COUNTER WHEELS INTO CONTACT WITH THE STRIP AT THE START OF A MEASURING OPERATION, TIME DELAY MEANS FOR SIMULTANEOUSLY CONNECTING THE COUNTERS TO THE THEIR RESPECTIVE PHOTOELECTRIC DEVICES AFTER A TIME INTERVAL DURING WHICH THE COUNTER WHEELS REACH THEIR OPERATING SPEED, AND MEANS FOR SIMULTANEOUSLY DISCONNECTING BOTH COUNTERS FROM THEIR RESPECTIVE PHOTOELECTRIC DEVICES AFTER ONE OF THE COUNTERS REACHES A COUNT EQUAL TO TEN RAISED TO A POSITIVE INTEGRAL POWER.

Claim 2

AN APPARATUS FOR MEASURING THE PERCENT CHANGE IN LENGTH OF A MOVING CONTINUOUS STRIP OF MATERIAL RESULTING FROM FORMING THE STRIP ABOUT A CABLE CORE BY MEANS OF A FORMING DEVICE COMPRISING: A FIRST PHOTOELECTRIC DEVICE LOCATED IN ADVANCE OF THE FORMING DEVICE AND INCLUDING A LIGHT SOURCE GENERATING A BEAM AND A RECEIVER ON WHICH THE BEAM PERIODICALLY IMPINGES, A FIRST COUNTER WHEEL POSITIONED INTERMEDIATE THE SOURCE AND THE RECEIVER AND MOVABLE INTO CONTACT WITH THE STRIP, SAID WHEEL INCLUDING A CIRCULAR ARRAY OF OPENINGS WHICH PERIODAICALLY PASS SAID BEAM TO THE RECEIVER AS THE WHEEL ROTATES, SAID BEAM THEREBY GENERATING PULSES AT A RATE PROPORTIONAL TO THE LINEAR RATE OF MOVEMENT OF THE STRIP PRIOR TO THE FORMATION OF THE STRIP ABOUT THE CABLE CORE, A FIRST COUNTER FOR MEASURING THE NUMBER OF PULSES GENERATED BY THE FIRST PHOTOELECTRIC DEVICE, A SECOND PHOTOELECTRIC DEVICE LOCATED BEYOND THE FORMING DEVICE INCLUDING A LIGHT SOURCE FOR GENERATING A BEAM AND A RECEIVER ON WHICH THE BEAM PERIODICALLY IMPINGES, A SECOND COUNTER WHEEL POSITIONED INTERMEDIATE THE SOURCE AND THE RECEIVER AND MOVABLE INTO CONTACT WITH THE STRIP AFTER IT HAS BEEN FORMED ABOUT THE CORE, SAID WHEEL INCLUDING A CIRCULAR ARRAY OF OPENINGS WHICH PERIODICALLY PASS SAID BEAM TO THE RECEIVER AS THE WHEEL ROTATES, SAID BEAM THEREBY GENERATING PULSES AT A RATE PROPORTIONAL TO THE LINEAR RATE OF MOVEMENT OF THE STRIP FORMED ABOUT THE CABLE CORE, A SECOND COUNTER FOR MEASURING THE NUMBER OF PULSES GENERATED BY THE SECOND PHOTOELECTRIC DEVICE, AND MEANS FOR MOVING THE COUNTER WHEELS INTO CONTACT AND OUT OF CONTACT WITH THE STRIP, CIRCUIT MEANS INCLUDING: MEANS FOR OPERATING THE MOVING MEANS TO MOVE THE COUNTER WHEELS INTO CONTACT WITH THE STRIP AT THE START OF A MEASURING OPERATION, TIME DELAY MEANS FOR SIMULTANEOUSLY CONNECTING THE COUNTERS TO THE THEIR RESPECTIVE PHOTOELECTRIC DEVICES AFTER A TIME INTERVAL DURING WHICH THE COUNTER WHEELS REACH THEIR OPERATING SPEED, AND MEANS FOR SIMULTANEOUSLY DISCONNECTING BOTH COUNTERS FROM THEIR RESPECTIVE PHOTOELECTRIC DEVICES AFTER ONE OF THE COUNTERS REACHES A COUNT EQUAL TO TEN RAISED TO A POSITIVE INTEGRAL POWER.
