Abstract

354,668. Kinematograph apparatus. ZEISS IKON AKT.-GES., 72, Schandauer Strasse, Dresden, Germany. Dec. 18, 1930, No. 38233. Convention date, Dec. 18, 1929. [Class 97 (i).] A kinematograph projector having permanently mounted sprockets each adapted for use with films of different widths is characterized by the provision of detachable and interchangeable units each comprising a film gate, picture window and pressure rollers for the sprockets, the various interchangeable units being designed for films of different widths. As shown in the Figure, the unitary structure A comprises a film gate 1 on which are mounted arms 2 which carry pairs of pressure rollers 3 co-operating with the various film sprockets, which have two or more sets of teeth adapted to fit films of different widths.
