Abstract
198,684. RÚmy, A., Renaux, J., Delort, J., and Debrebant, F. June 1, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Driving.-A record is driven during recording and reproducing so that the sound trace is cut or reproduced at a constant linear speed, thereby increasing the sound impressions recorded per unit area. For this purpose, the turntable may be driven by a friction roller whilst receiving a translating movement in its own plane, or the friction roller and stylus may be moved radially of the turntable.
