Abstract

471,092. Kinematograph picture and sound films. SIEMENS & HALSKE AKT.- GES. Jan. 11, 1937, No. 844. Convention date, Jan. 9, 1936. [Class 98 (ii)] To produce combined lenticular colour and sound films, an original picture film is developed as a positive by the reversal process and an original sound film is developed as a separate negative and both are then copied on to the same lenticular copy film which is developed by reversal. The picture film may be copied by projection printing and the sound film by contact printing.
