Abstract: 450,502. Optical sound-reproducing apparatus. RADIO CORPORATION OF AMERICA, 30, Rockefeller Plaza, New York, U.S.A. Nov. 11, 1935, No. 31186. Convention date, Jan. 19. [Class 40 (ii)] An apparatus for reproducing sound from sound records comprises means for producing a plurality of light beams acoustically modulated by the sound record, a light sensitive device provided with a plurality of cathodes and means operable to cause said beams to be applied selectively to the same or to different cathodes of said device according to whether the negative and positive sound impulses are recorded on the same or different tracks or areas. As shown, light from a source 10 after passing through an optical system 12 is modulated by the film 11 and is then transmitted through lenses 13 and is split by lenses 14, 15 into two separate beams, one of which is applied to the stationary reflector 16 and the other to an adjustable reflector 17. When reproducing a record of the kind described in Specification 406,872 in which the negative and positive impulses are separately recorded on tracks spaced from one another, the reflectors 16, 17 are arranged in the full-line position when one of the acoustically modulated light beams is reflected by the reflector 16 on to the cathode 18 of the light sensitive device 19 and the other light beam is reflected by reflector 17 on to the cathode 21 of the device 19. When, however, it is desired to reproduce a record having all the sound components recorded on a single track, the reflector 17 is shifted to the dotted line position when both light beams are reflected on to the cathode 18.

Title: Arrangement for producing an electroluminescent light spot, controllably variable in its position
IPC: H05B33/12
Filed: 1961-09-08
Abstract: An electroluminescent apparatus produces an area of light on an indicator surface, the position of which is controllably variable with respect to one co-ordinate of a system of co-ordinates defining points on the surface, the other coordinate appropriate to position of the area having a constant value.  As shown Fig. 1 a wedged-shaped electroluminescent capacitor 1 is bounded by conductive surfaces 9 10 which <FORM:0998911/C4-C5/1> have a voltage from a source 2 applied to them. Disposed adjacent the light transparent conductor 9 is a set of pairs of similar light-sensitive resistors 3, 3a, the mid-points 4 of which are each connected to an electroluminescent capacitor 5. Upon excitation of the capacitor 1, which may contain a polaristor layer, light is emitted from the phosphor from the narrow end up to a certain point, the adjacent capacitor 5 to this point being excited due to its associated resistors 3, 3a receiving differing incident light intensities. In an alternative method of obtaining a variation of the field intensity, one of the conductive surfaces is made resistive and disposed parallel to the other surface. The light output from the second electroluminescent capacitor may be viewed directly or allowed to fall on one of a set of photo-conductive elements so as to alter the potential of a conductor attached to one side of the element.  In using the apparatus for television pick-up or display apparatus, a plurality of parallel conductors are each associated with a photoconductive element, and are disposed at right angles to a similar set of conductors, thus forming a cartesian coordinate system, a further electroluminescent layer being interposed between the sets.  In voltage measuring apparatus, a scale may be provided along the set of capacitors 5 of Fig. 1, and the voltage of the source 2 directly read off. Alternatively, the voltage measured may be displayed on a digital display device consisting of a number of electroluminescent strips, the energizing of which is controlled by connecting each to a photo-conductive strip which is illuminated through an apertured mask by the spot of light produced in the second set of electroluminescent capacitors.  The apparatus may be used to convert an infra-red or an X-ray image into a visible image.  Copper activated zinc sulphide or copper activated cadmium selenide embedded in an epoxy resin may be used as the electroluminescent phosphor.
