Abstract

714,881. Kinematograph films bearing sound tracks. PYRAL SOC. AR.L. April 16, 1952 [July 19, 1951], No. 9548/52. Class 98(2) [Also in Group VIII] One or two magnetic sound tracks may be deposited as a liquid coating on kinematograph film by a web-coating apparatus [see Group VIII]. As shown, a single track p, Fig. 9, may be deposited on the picture area of a film f with one row of perforations, or one or two tracks p, Fig. 11, may be deposited outside the perforations on a 16 or 35 mm. film.
