Abstract

538,472. Reproducing recorded oscillations. FAIRWEATHER, W. C. (Kollsman, P.). Dec. 28, 1939, No. 3757/41. Divided out of 535,328. [Class 40 (ii)] An apparatus for reproducing oscillations from the electro-static film record described in Specification 535,328 comprises a rotary cylinder 5 with a pair of rollers 6 for feeding the film 2 over and around the roller, an electrode 14 adjacent the cylinder, and a valve amplifier 15 connected between the electrode and the cylinder as shown. Specification 384,528, [Group XXXVII], and U.S.A. Specification 1,891,780 also are referred to.
