IPC: H03K4/32
Filed: 1942-07-24
Abstract: 558,927. Television; valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and AMBROSE, D. M. July 24, 1942, No. 10371. [Classes 40 (iii) and 40 (v)] A scanning arrangement for a television cathode-ray tube comprises a generator of sawtooth waves, an inductive circuit L for applying the waves to the electron beam of the tube, and a hard valve V2 normally biased to cut-off and having its anode circuit connected to shunt the inductive circuit, means being provided for unblocking the hard valve only during the periods of the fly-back strokes of the saw-tooth waves. As shown in Fig. 1, the circuit comprising the inductance L and the hard valve V2 is supplied from a generator of saw-tooth waves G through an amplifying valve VI. The saw-tooth waves are also fed through an amplifier V3 and a transformer T to the grid circuit of the hard valve V2, so that this valve is rendered conductive only during the fly-back periods of the saw-tooth waves. During this conductivity serves to damp undesired oscillations in the inductive circuit. Reference is made to Specification 457,929 for similar circuits but using neon or other gas-filled valves in place of the hard valve V2.
Patent GB-422379-A (GB)
Title: Improvements in the production of photographic and kinematographic color positives
IPC: G03C7/20
Filed: 1934-04-06
Abstract: 422,379. Colour photography and kinematography. THORNTON, J. E., 8, Hill Street, Jersey, Channel Islands. April 6, 1934, No. 10390. Drawings to Specification. [Class 98 (ii)] In a process of producing coloured photographic and kinematograph positives, the colour record images from a two-colour broken-tone negative are printed in register on opposite sides of a double-coated positive stock, the light being slightly spread by a diffusing arrangement, e.g. a ground glass, to give a substantially continuous-tone record, and the silver images are coloured by applying layers of colloid coloured in complementary colours to opposite sides, treating the combination in a bath which bleaches the silver image and hardens the colloid in contact therewith, and washing out the bleached silver image with hypo and the unhardened colloid with hot or cold water. For example, a support of cellulose acetate is coated with an adhesive substratum on both sides and a fine grain panchromatic silver halide emulsion applied to each side. If desired, a light-obstructing layer as in Specification 9324/12, [Clase 98 (ii)], may be applied between the layers. Component colour records from a mosaic two-colour negative are printed on opposite sides of this material through a red and a green filter respectively, a prismatic screen, a prism double-image device, or a disc rotating at an angle being interposed in the light beam. After development, a porous paper support coated with a layer of colloid, e.g. gelatin, fish-glue albumen, gum arabic, gum tragacanth, agar-agar or casein coloured by means of dyes or pigments, is applied to each side, or the colloid may be applied in liquid form by coating, brushing or floating methods. The colloid in contact with the red part-image is coloured green and vice versa. The material is then treated with a bleaching hardening bath, e.g. containing bichromate, ferricyanide and bromide salts or copper salts or chromic acid and the unhardened colloid washed out. The bleached silver images are then removed with hypo. The process may be duplicated, using, for example, green and crimson-violet and orange and blue-violet and the resulting film cemented together for a fourcolour result. A two-colour film produced by the process may be combined with a third image formed in a different manner. In the case of kinematograph films a continuous-tone negative may be made from the original as described above and used to print the positives for colouring. Specifications 224,572, [Class 98 (ii)], 414,056, 417,640, 417,722 ; 417,765 and 417,766, [both in Group XXXVIII], also are referred to. Reference has been directed by the Comptroller to Specification. 414,036.
