Abstract

149,206. Mylo, R., (Assignee of Lenczycki, M.). Nov. 10, 1915, [Convention date]. Optical machines; optical records.-In order to obtain a photographic record of sound-waves, a moving phonographic record a varies the width of a slot d in a shutter through which a beam of light passes on to a moving photographic plate or film. The record a may be of the cylinder or disk type or of the magnetic ribbon or wire type. The shutter may have several pairs of slits, as shown in Fig. 3, or may be replaced by a number of shutters. The Specification as open to inspection under Sect. 91 (3) (a) states that the record a is moved at a speed appropriate to the sensitiveness of the film employed, the shutter movements being thus slower than if they were influenced by sound waves. This subject-matter does not appear in the Specification as accepted,
