Abstract
469,928. Kinematograph apparatus; television apparatus &c. INTERNATIONALE TOBIS MAATSCHAPPIJ N. V. Dec. 7, 1936, No. 33561. Convention date, Jan. 10. [Class 97 (i)] [Also in Group XL] In kinematograph, television and other apparatus comprising optical elements, mechanical parts, and a sound-proof cover or casing, &c., only the optical elements which require to be rigidly connected to the apparatus are housed within the casing, and one or more further optical devices are mounted externally on the casing, or on a member separate therefrom. The further optical devices may consist of supplementary lenses, telephoto objectives, colour or polarizing filters, diaphragms, &c., and may replace a plane-parallel glass disc covering a light aperture in the casing, or may be additional thereto ; they may be adjustable or changeable, and, if they are such as to require changing periodically, for example multi-colour filters, they may be driven through resilient couplings or the like from the drive of the apparatus. In apparatus for electrically transmitting pictures and sound the scanning means may be within the casing.
