Abstract

501,259. Recording sound &c. mechanically on films. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Sept. 5, 1938, No. 25940. Convention date, Sept. 8, 1937. [Class 40 (ii)] Relates to apparatus for recording sound and like vibrations on a film by means of a recorder comprising an armature having a high resonance frequency, the film passing over a stationary support at the recording point. According to the invention, in order to minimize the disturbing effect of shocks, the supporting means for the armature is directly connected to the stationary film support. As shown applied to apparatus for making a record by means of a V-shaped chisel for optical repro. duction, the film 1 passes at the recording point over a hard steel inset 4 in a block 10, and the member 10 is directly connected to the housing 11 of the recorder by means of an ear 14 on the latter. The connection at 16 is adjustable, so that the depth of out may be varied. The recording-device is constructed as described in Specification 441,747, [Group XXXIX].
