Abstract
488,559. Optical sound-reproducing processes. LEER, J. O. VAN. Jan. 6, 1937, No. 434. Convention date, Jan. 6, 1936. [Class 40 (ii)] [Also in Group XX] In an optical process for reproducing sound with or without pictures from a film consisting of a carrier with light-modulating colouring- matter, the common components of the colour of the scanning light, the colour of the filter for the scanning light, the colour of the carrier, and the colour of the light to which the photoelectric cell is most sensitive, are absorbed by the modulating colouring-matter. In an example, an uncoloured carrier may have translucent and opaque portions so coloured, e.g. red and green, as to have no common colour component and a coloured field graded from red at one end to green at the other may be displaced by an oscillograph over a light slit past which the film is moved. Specification 448,976 is referred to.
