Abstract

455,122. Phonographic recorders. BORNHAUSER & CIE, P. J., 15, Fraunmunsterstrasse, Zurich, Switzerland. Jan. 17, 1936, No. 1563. Convention date, Dec. 13, 1935. [Class 40 (iv)] In apparatus for recording acoustic oscillations and comprising an electrically-operated diaphragm 7 adapted to close over one end of a sound-conducting tube 8 into the other end of which is fitted an acoustically-operated recording sound-box, the electrically-operated diaphragm 7 is larger than the diaphragm 9 of the recording sound-box so that the movement of the diaphragm 7 produces greater amplitude of movement of the diaphragm 9. The microphone 1 and associated apparatus may be located at a distance from the recording apparatus and the tone arm 13 is provided with a movable flap 21 which, in the open position, allows speech from the distant transmitter to be heard by the supervisor of the recording apparatus. The tone arm is traversed across the record 19 by a half nut 14 engaged by a screwed spindle 15 driven by gears from a motor 12.
