Abstract
371,902. Combined sound and picture films. NAAMLOOZE VENNOOTSCHAP KœCHENMEISTER'S INTERNATIONALE MAATSCHAPPIJ VOOR SPREKENDE FILMS, 305, Keizersgracht, Amsterdam.- (Assignees of Tonbild Syndikat Akt.-Ges.; 43, Mauerstrasse, Berlin.) Oct. 27, 1930, No. 32276. Convention date, Oct. 29, 1929. [Class 40 (ii).] Relates to processes for making talking- picture films in which light-sensitive emulsions of different compositions (e.g. of different sensitivity or granulation) are used. According to the invention, the sound and picture records are produced on a single film provided on opposite sides with emulsions of different kinds, and both records on the film are developed together. The emulsions are selected so as to be specially suitable for the sound and picture records respectively. Preferably, each emulsion does not extend over the whole width of the film, but only over such portion as is exposed during the making of the individual record. Both sides of the film may, however, be completely coated, and the unwanted portion removed from each side of the completed negative. The two layers may be made on an opaque film, which is subsequently either made transparent or is used for reproduction by reflected light.
