Patent GB-1301824-A (GB)
IPC: H04N9/64
Filed: 1970-01-16
Abstract: 1301824 Television BLAUPUNKT-WERKE GmbH 16 Jan 1970 [17 Jan 1969] 2155/70 Heading H4F A known method of separating the chrominance portion of a PAL signal from the luminance portion consists in passing both signals through an IF amplifier and demodulator having a pass above 15 which falls to about 50% at the subcarrier fundamental frequency FT, and providing a peaking filter with a characteristic 16 to give an overall response 17. However since the lower chrominance sideband is broader than the upper sideband, on demodulation the sideband add to give a response curve 22, which produces ringing in square wave chrominance signals for example. A smoother response curve 25 after demodulation gives better transient response, e.g. gives a single transient pulse at each edge of a square wave which provides a colour sharpness enhancement, and is produced by giving the amplitude modulated chrominance signal amplifier a pass curve 24 which, in combination with IF curve 15, gives an overall pass curve 23 that drops steeply in the vecinity of the subcarrier fundamental FT. It is also possible for the curve 23 to be in the form of a mirror image on the other side of the line FT, in which case the curve 15 should have a greater bandwidth. In a modification a separate chrominance IF amplifier immediately follows the common chrominance and luminance amplifier and this alone has a required band bass curve 23.

Patent GB-393226-A (GB)
Title: Improvements in and relating to electric circuit breakers with arc-extinguishing arrangements
IPC: H01H33/985
Filed: 1933-01-25
Abstract: 393,226. Arc-rupturing in switches. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Felten & Guilleaume Carlswerk Akt.-Ges. ; M³lheim, Cologne, Germany.) Jan. 25, 1933, No. 2449. [Class 38 (v).] The fixed contact d is located in an arcing- chamber b which communicates by means of conduits i in the wall of a cylinder c with the space in that cylinder above a piston g that is fixed to the movable contact e. The cylinder c, conduits i, and chamber b contain a gas, such as carbon dioxide, chlorine, ammonia, or sulphur dioxide, so that when the contact e is raised to open the circuit, the piston g compresses the gas above it in the cylinder c and the pressure is communicated to the arcchamber b. At the same time, a vacuum is formed beneath the piston, so that when the contact e nears the full-open position and a pin h thereon lifts a spring-controlled valve f from its seating, the gas escapes from chamber b into the evacuated space in c and extinguishes the arc. Valves l in the piston g permit easy closure of the switch, while valves m, f serve to prevent generation of excessive pressures within c, b respectively. The gas is cooled during compression by its passage through i so that compression takes place isothermally, and the conduits i serve also to filter the gas by removing metallic particles in the event of the gas being used for several reclosures. Loss of gas may be made good from a reservoir such as n which communicates with the chamber b by a valve p. A valve q is adapted to close a signalling circuit at r when the supply in the receiver gets low. The Specification refers also to the use, instead of gas, of a vapour formed by the arc from a liquid.

Patent GB-555014-A (GB)
Title: Photographic material for colour photography
IPC: G03C1/825
Filed: 1942-02-27
Abstract: 555,014. Photographic antihalation and filter layers. TULL, A. G. Feb. 27, 1942, No. 2584. [Classes 97 (i) and 98 (ii)] In multilayer sensitive material for colour photography a coloured antihalation or filter layer comprises a colloid binder such as gelatin containing as colouring matter an insoluble chromate of a metal such as lead, zinc, or barium. The layer may be formed between an annular layer and the support or between two emulsion layers, and may be produced by preparing two gelatin solutions containing respectively reagents capable of reacting to form the insoluble chromate, e.g. a soluble lead salt in one solution and a soluble chromate in the other, and either (a) mixing the solutions and coating the mixture directly or after it has been allowed to set, shredded, washed, and remelted ; or (b) coating the solutions in succession so that the insoluble chromate is formed at the boundary between the coatings. Variants of case (b) consist in using an aqueous solution of the reacting salt, without gelatin, for the second coating ; applying a clear gelatin coating between the two coatings containing reactants, the insoluble chromate being formed mainly in the interlayer ; and using for the layers carrying the reacting salts silver halide emulsion layers. The coloured layer is decolorized by an acid or alkaline bath in the usual processing sequence for the sensitive material ; but a special decolorizing bath, e.g. of caustic soda, may be used. Reference is made to the use of insoluble metal ferrocyanides as the colouring matter for antihalation and filter layers.
