Abstract
793,683. Optical sound film recording systems. WESTREX CORPORATION. Sept. 28, 1956 [Oct. 4, 1955], No. 29688/56. Class 40 (2). An optical sound film recording system comprising means 7, 8, 9 for forming a pair of laterally offset light beams, means such as a pair of current-responsive ribbons 3, 4 individual to each of said light beams for separately modulating each of the beams in accordance with sounds to be recorded, lens 13 common to the pair of light beams for separately imaging the respective light-modulating means in the plane of the film F in laterally offset relation and optical means, such as a bi-plate or a bi-prism 20, disposed in the path of the light beams for doubling each of the images whereby one of the two images of one of the light-modulating means is adjacent one of the two images of the other light-modulating means within the sound track area of the film and whereby the two remaining images are located away from the sound track area and prevented from .falling on the film.
