Abstract

484,799. Combined sound and picture disc records. OKOLICSANYI, F. VON. Nov. 10, 1936, No. 30617. Convention date, Dec. 12, 1935. [Class 40 (ii)] [Also in Group XX] A combined sound and picture disc record in which interposed between spirals of photographically produced pictures there are depressions 2 filled with material in which the sound record is printed or impressed, has the pictures 4 spaced at intervals 5 determined by dividing the sound recording speed by the picture frequency, and by reducing the size of the pictures accordingly, the spaces between the pictures being blackened and being of much greater length than the length of a picture. A high picture frequency, e.g. 50 pictures per second, is used. A numerical example is furnished. The continuous movement of the record is compensated for, in recording or projecting the pictures at this frequency by using a mirror which is oscillated by an A.C. current of 50 cycles per second.
