[Class 40 (ii)] [Also in Group XL] A light-valve for use in optical sound recording comprises a magnetic frame 2 having a hollow polepiece 7 and a magnetic plate 5 provided with an aperture 10 and hollow polepiece 9 over the inner end of which are secured three plates 12, 13 and 14 forming between them a triangular aperture 11 of very small height in comparison to its base. A currentcarrying vibratory conductor 27 is stretched across the aperture 11, parallel to the base of the latter, being clamped by pieces 28, 29 to plates 22, 23 secured to bridges 18, 19. Each of these bridges carries a pair of jaws 32, 33 engaged by screws 36, 37 by which the position of the conductor with respect to the aperture can be adjusted prior to clamping. The ends of the conductor are secured to windlasses 38, 39 rotatably secured within insulated blocks 40, 41 and electrically connected to terminals 43, 44. Before reaching the windlass 39, the right-hand end of the conductor is looped over a spring-pressed arm 61 pivotally mounted at 62 to the plate 5. Fig. 4 shows the application of the light valve to a noiseless recording system in which the amplified currents from microphone 46 are fed through transformer 48 and conductors 49, 50 to the conductor 27, vibration of which in the magnetic gap modulates the light from a source 52 in its passage to the film 45. The conductor 27 is also controlled by a current, the intensity of which varies in accordance with the volume of the sound to be recorded, this current being obtained by byepassing a portion of the current from transformer 48 through an amplifier 56 and rectifier 57, the rectified current so obtained being applied either directly to the conductor 27 or in opposition to a steady biassing current from a battery 64. The mean biassing position of the conductor can be changed during recording by adjustment of potentiometers 58, 59.

Title: Improved process for producing multi-layer photographic color negatives containing masking images for color correction purposes
IPC: G03C7/18
Filed: 1948-06-04
Abstract: 638,048. Colour photography. GENERAL ANILINE & FILM CORPORATION. June 4, 1948, No. 15163. Convention date, Nov. 18, 1947. [Class 98 (ii)] A subtractively coloured negative incorporating colour-correction printing masks is made by exposing to a coloured object a multilayer film having silver halide emulsion layers sensitive to the blue, green and red regions of the spectrum and containing colour formers, colour developing, short stopping in an acid bath, washing, bleaching the developed silver to silver bromide, exposing to a controlled quantity of white light, developing in a black and white developer containing 0.02 to 0.4 gram per litre of a depth controlling re-agent of 1-mercapto-benzimidazol, 1-mercapto-benzimidazol-4-sulphonic acid, phenyl-mercaptotetrazol or 2-mercapto-benzthiazol ; fixing, washing and drying. Silver masks are thereby formed in the magenta and cyan layers (originally green and red sensitive, respectively) but not in the yellow coloured, blue-sensitive layer. The depth controlling reagents desensitize the upper strata of the emulsion layers but do not penetrate to the deeper sections, where the developer acts normally. The re-formed silver bromide, in situ with the coloured images is much less sensitive than the residual silver halide left after colour development and so the controlled exposure to white light does not form latent images therein. In examples this controlled exposure is 15 seconds at 5 feet from a 100 watt lamp, and the colour developing, the bleeching and the depth-developing solutions are specified. Specifications 458,400, 465,823, 489,161, 489,274, 491,958, 541,266 and 637,876 are referred to.
