Abstract
632,354. Recording-apparatus. OPPEGAARD, K. F. Sept. 6, 1941, No. 11402. [Class 106 (iv)] [Also in Group XXXVI] A record of a voltage is made on a moving strip B by one of a plurality of pins moving transversely to the strip (e.g. carried by the wheel R) which receives an impulse when the sum or difference of the voltage to be recorded and an auxiliary periodically-varying voltage reaches a predetermined value. The voltage to be measured is applied at Ex= and together with the potential from a potentiometer P is fed to the input of a thyratron T; the contact S of the potentiometer moves with the wheel R, so that when the sum or difference of the voltage at Ex= and S reaches a predetermined value, the thyratron T conducts to allow condenser C1 to discharge to give an impulse to the pin to record electrolytically or by a spark to the strip B. The thyratron is extinguished by a commutator breaking its anode circuit or by the voltage drop generated across resistance W2. In a modification, the potentiometer is replaced by a sawtooth oscillator synchronized with the wheel R, Fig. 2, not shown. The voltage Ex= may be replaced by a rectified alternating voltage Ex-. The wheel R may be geared with a commutator to record successively voltages from different sources.
