Abstract

351,927. Kinematograph films; optical systems. CHRETIEN, H., 23, Rue Preschez, St. Cloud, Seine-et-Oise, France. Dec. 30, 1929, No. 39742. Convention date, Jan. 28. [Classes 97 (i) and 98 (ii).] The images on a kinematograph film of standard width bearing a sound record 5 are optically compressed laterally, during taking or printing, so as to provide space for the sound record. The images are restored to their normal shape during projection, and the taking and projecting systems comprise an objective 16, Fig. 6, a teleobjective, or a projective lens, and a pair of cylindrical lenses LL<1>. Specification 334,708, [Class 97 (i), Optical systems &c.], is referred to.
