GEAR MEASURING LENGTH OF MOVING LONG-LENGTH MATERIAL Russian patent published in 1997 - IPC

FIELD: measurement technology, measurement of length of moving long-length materials while manufacturing film materials, cloth, paper making and rubber industry. SUBSTANCE: gear measuring length of moving long-length materials has measuring roller, calculator of measured length, digital information unit, optoelectron pulse sensor, current amplifier, "current loop" stub, optron decoupling unit, rectangular pulse former, "logic" filter unit, address decoder, unit of energy-independent memory. It is advantageous to make optoelectron pulse sensor in the form of disc with radial holes and two optrons arranged for possible phase shift of generated pulses through 90 deg. "Logic" filter unit is manufactured in the form of two inverters, two RC networks and two 3AND gates. EFFECT: enhanced accuracy and expanded functional capabilities. 3 cl, 2 dwg
