Title: Improvements in or relating to gamma correction in television apparatus
IPC: H04N5/257
Filed: 1960-10-26
Abstract: 962,565. Television. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 28, 1960 [Oct. 27, 1959], No. 36760/60. Heading H4F. The beam intensity of a flying-spot scanner 1 (Fig. 1), which scans a transparency 2 is controlled in accordance with non-linearly amplified signals representative of the L.F. components of the television signals produced by a photo-electric device 3 from scanning light transmitted through transparency 2. Assuming the latter to have a " gamma " Y, a desired " gamma " Y 1/gamma of the output signals fed from amplifier 4 to the transistor 5 is produced by supplying the signals from amplifier 4 to an amplifier 7 having a characteristic (1/gamma 1) and thence via a low-pass filter 8 and delay device 9 (which increases the inherent delay from a few micro-seconds to the duration of a fullline scan) to the intensity control electrode of tube 1. If the delay device 9 has the required low-frequency pass response the filter 8 may be omitted. Fig. 2 shows the application of the invention to a three-colour, R(red), G(green), B(blue) system. In this arrangement light transmitted through the colour transparency 2 is selectively directed by means of dichroics 10R, 10G, 10B on to photo-electric devices 3R, 3G, 3B and the output of the latter combined in circuit 11 to provide a luminance signal L 1/gamma which is fed via delay device 9 (also acting as a L.P.F.) and amplifier 7 (having a charac- 1 teristic - - 1) to control the intensity of the Y beam of the flying-spot scanning tube 1. The outputs of the photo-electric devices are also fed to a matrix 12 controlling the colour saturation and then to a coding device 13 (e.g. to produce signals of the N.T.S.C. type) before application to the transmitter 5. Specification 904,018 is referred to.

Title: Process and apparatus for the production of gases containing carbon monoxide and hydrogen
IPC: C10J3/46
Filed: 1954-12-21
Abstract: 760,385. Gasifying carbonaceous fuels. KOPPERS GES., H. Dec. 21, 1954 [Dec. 24, 1953], No. 36934/54. Classes 55 (1) and 55 (2). A process of gasifying powdered solid, liquid or gaseous carbonaceous fuels comprises forming a first mixture of a fuel and oxygen or oxygen-enriched air, the amount of oxygen in the mixture being in excess of the amount necessary to convert all of the carbon of the fuel in the mixture to carbon dioxide, forming a second mixture of a fuel and oxygen or oxygen-enriched air, the amount of oxygen in the second mixture being less than the amount necessary to convert all of the carbon of the fuel in the second mixture to carbon dioxide and the total oxygen content of both mixtures being insufficient to convert the total carbon content of both mixtures to carbon dioxide, injecting the first mixture into a reaction chamber maintained at at least the ignition temperature of the mixture so that the first mixture ignites immediately on entering the reaction chamber, injecting the second mixture into the reaction chamber so that the hot products of combustion of the first mixture promote partial combustion of the fuel in the second mixture and forming therewith a third mixture which is contacted with an endothermic gasifying agent comprising steam and/or carbon dioxide. The endothermic gasifying agent is introduced into the reaction chamber as an annular stream surrounding the first mixture and the second mixture is injected between the two and is directed into the combustion zone of the first mixture. A quantity of fuel up to about 5 per cent of the total fuel is incorporated in the first mixture and finely-divided non-volatile inorganic material may be included in the mixture to increase the amount of heat radiated to the second mixture. Suitable inorganic materials are powdered ashes, metal oxides, particularly those of alkaline earth metals and metal salts. Any combination of liquid, gaseous or solid fuels may be used in the two mixtures of fuel and oxygen or oxygenenriched air. The steam as endothermic gasifying agent is superheated to 500-600‹ C. and in an example the gas produced contained 43 per cent each of carbon non-oxide and hydrogen. Apparatus for carrying out the process comprises an injector nozzle for the first mixture, a coaxial annular nozzle for the endothermic gasifying agent and one or more conduits located between the above two nozzles for the injection of the second mixture.

Title: Production of synthetic resin or like surface coatings by electrode position
Inventor: MELL CEDRIC CHARLES
IPC: C25D13/22
Filed: 1963-09-23
Abstract: A coherent non-metallic coating is formed on a conductive article by electro-deposition from an aqueous bath by effecting deposition under such conditions that a deposit is produced of a thickness dependent mainly on the deposition time and thereafter continuing deposition under conditions which produce a further deposit with resistance which increases with the time of treatment.  Typically the initial deposition is effected at a low voltage and the further deposition is performed at a higher voltage which serves also to reduce the water content of the whole coating.  The two stages may be carried out in the same or different baths.  In one example an aqueous dispersion of styrenebutadiene copolymer stabilized with an anionic surfactant and containing TiO2 pigment is used to anodically coat a metal article using initially an applied voltage of 0.5 to 10 volts to give a current density of 0.1 to 0.6 amp/dm2 followed by a second coating with 40 volts applied to give a final coating thickness of 1.5 to 2 mils.  In a further example a similar bath including red iron oxide is used with an applied voltage of 0.5 to 20 volts to provide the initial coating and the article is subsequently subjected to anodic deposition in an ammoniacal solution of an alkyd resin pigmented with TiO2 with an applied voltage of 30 to 100v.  A yet further example uses low voltage anodic deposition from a surfactant stabilized pigmented acrylic acid copolymer followed by high voltage anodic deposition from a pigmented ammoniacal solution of an acrylic acid copolymer.  Other resin compositions suitable are mixtures or products of chemical reactions of alkyd resins or maleinised oils or fatty acids with phenolic resins with or without copolymerization with a vinyl monomer, e.g. styrene, or modified with epoxy resins; mixtures of alkyd and amino resins; alkyd resins modified with allyl ethers of polyol with or without additional modification with phenolic or amino resins; alkyd resins based on polyethylene oxide; or vinyl or acrylate polymers or copolymers.  The deposited coatings may be baked or stoved to drive off the aqueous component and/or to effect curing.  To avoid staining when coating iron articles, the articles may be electro-plated with Zn or Cd as in Specification 1,078,199.

Abstract: 1401008 Pattern recognition systems MULLARD Ltd 27 June 1972 [17 Aug 1971 (2) 1 March 1972] 38527/71 and 38528/71 Heading G4R Apparatus which may be used in pattern or character recognition apparatus includes means for defining an edge contour of the pattern. The pattern may be represented by a regular or irregular array of black pattern points and white background points. The edge contour is represented by a succession of straight lines (vectors) joining contour points. Each line passes between a black point at the edge of the pattern and a neighbouring white point, or passes through that white point. The edge contour thus lies wholly outside the area covered by the pattern. The edge contour is derived by examining groups of the array points in turn and comparing each group with arrangements of array points (operators) which define the possible vectors. For example, if the array points form a rectangular matrix, groups of 2 Î 2 points may be examined. Each group in turn is compared simultaneously with the 4-point operators shown in Fig. C1. Each operator defines the edge vector as shown. It is desirable that each vector should indicate the centre of the next group of 2 x 2 points to be compared, e.g. so that the address in storage of the next group to be compared can be obtained by incrementing address counters, it then being unnecessary to examine all the groups forming the array but only those at the edge of the pattern. This is not always the case with the operators in Fig. C1. The operators shown in Fig. D1 do fulfil this requirement. Here array points occupying a cruciform shape are examined, four or five points in the array being significant. Such operators produce an edge contour as shown in Fig. B, for example. The points of the array may be taken to define triangles rather than squares. In such a ease six-point operators, of which three points are significant, may be used, Fig. 12. The apparatus may be used for non-regular arrays of points.
