Abstract

928,617. Electric selective signalling systems. ELLIOTT BROS. (LONDON) Ltd. March 1, 1962 [March 2, 1961], No. 7743/61. Class 40 (1). Apparatus for integrating a D.C. voltage includes a relaxation oscillator which produces a train of pulses the pulse repetition frequency and polarity of which are respectively dependent on the amplitude and polarity of the D.C. voltage, and a counter forms the algebraic sum of the pulses. The counter may be of the type producing a mechanical output and may, through gearing if desired, position the slider of a potentiometer so as to give an output voltage which is representative of the time integral of the D.C. voltage.
