Abstract

456,791. Combined sound and picture records. INTERNATIONALE TOBIS MAATSCHAPPIJ NAAMLOOZE VENNOOTSCHAP, 305, Keizersgracht, Amsterdam.- (Assignees of Tobis Tonbild-Syndikat Akt.- Ges.; 43, Mauerstrasse, Berlin) Dec. 19, 1935, No. 35216. Convention date, Dec. 19, 1934. [Class 98 (ii)] A method of taking picture and sound records on a single photographic carrier comprises providing the carrier with a photographic emulsion of very fine grain over both the picture record area and the sound record area, the emulsion having a finer grain than normal kinematographic picture record emulsions, traversing the photographic carrier past means for producing a sound record thereon of normal or substantially normal length and also traversing the carrier past an optical system for producing a picture record on the carrier having the normal number of pictures per unit length of the sound record but which is of such short focus that each picture is considerably smaller in both height and width than the picture size usual for the length of picture advance employed. As shown, on the fihn 1 the sound track 2 is of normal dimensions, but the picture records 4 are of reduced dimensions. The vacant spaces may be occupied by additional series of picture records, additional sound tracks being provided, or by perforations. The method may be applied to multilayer, colour, and stereoscopic films. The picture records may be turned through 90‹. Separate emulsions for the picture and sound records may be arranged on the same film.
