Title: Improvements in or relating to colour television receivers
IPC: H04N9/24
Filed: 1954-02-02
Abstract: 752,662. Colour television. GENERAL ELECTRIC CO., Ltd., and BIGGS, A. J. Feb. 2, 1955 [Feb. 2, 1954], No. 3085/54. Class 40 (3). Relates to a colour television receiver incorporating a cathode-ray tube 10, the screen of which, Fig. 2, comprises a repeating sequence of blue, green and red luminous strips 9, 10, 11 arranged to be scanned with the line direction transverse the strips, and concerns the utilization of received blue, green and red video signals in channels 4, 5, 6 to control the tube beam at instants coinciding with the scanning of the corresponding colours. Metallic strips 12 are deposited over each luminous strip and connected together in three sets corresponding to the three colours. Connections 13, 14, 15 from the three sets are taken out from the tube envelope to resistors 20, 21, 22 across which pulse trains appear during scanning. The pulse trains are applied to limiter stages 24, 25, 26 and thence via amplifiers 27, 28, 29 to modulate the cathode-ray beam so that each pulse controls the beam during the scanning of the corresponding luminous strip. The modulation is in such a sense that each pulse reduces the beam current, and the amplification of each of the amplifiers is controlled by the video signal in the corresponding channel 4-6 so that the amplification is maximum when the video signal is zero and a minimum when the video signal is a maximum. By this means, as the scanning proceeds, the beam is modulated by pulses at the appropriate instants to ensure the luminous strips are correctly impinged, and the pulse amplitude are at each instant determined by the corresponding colour signal so that the images corresponding to the three colours are accurately produced. The amplifiers are adjusted so that the beam current is never allowed to fall below a minimum value, even though the component colour signal is at black level. As an alternative to the use of metallic strips 12 to derive the pulse signals, photo-electric cells responsive to each of the colours may view the screen, or the luminous strips may be arranged to exhibit a different coefficient of secondary emission for each colour so that distinguishable pulses may be derived from an auxiliary collector electrode. The widths and spacings of the luminous strips may vary to compensate their differing efficiencies. Individual colour phosphors may be employed or a uniform white phosphor with an optical strip filter.
Patent GB-884163-A (GB)
Title: Improvements in or relating to artificial filamentary structures
IPC: D01D5/42
Filed: 1960-01-28
Abstract: Composite filamentary structures are produced by simultaneously spinning fibre-forming polymers of at least two types, of which p  at least one is an elastomer and at least one other is a synthetic polymer capable of being extruded and drawn to yield filaments having an elongation substantially less than that of the filaments made from the elastomer or elastomers, the spinning being carried out under such conditions that the elastomeric filaments adhere to the non-elastomeric filaments to form composite filamentary structures, the adhesion in which can be broken in subsequent drawing operations to form a bulky yarn-like structure.  The composite filamentary structures are drawn by an amount less than the breaking elongation of the components but beyond any irreversible extension of the elastomeric component or components, preferably at least twice the original length.  They are then converted into a bulky yarn-like structure by relaxation so as to allow retraction.  The elastic filaments are then still substantially straight and the non-elastic filaments randomly looped about them.  In an example, a segmented condensation elastomer is prepared by condensing poly (tetramethylene oxide) glycol (1 mol.) having a molecular weight of 1,000 with 0,5 mol. of toluene diisocyanate.  1 Mol. of the resulting dimer is then reacted with 2 mols. of methylene bis(4-phenyl-isocyanate).  The resulting polyether diurethane (1 mol.) is then reacted with 1 mol. of hydrazine monohydrate to produce a copolymer.  A spinning solution in dimethyl formamide, containing 20% of the above polymer, 5% of N,N-diethylaminoethyl methacrylate and 5% of titanium dioxide (both based on the polymer), and a 27% solution in dimethyl formamide of the copolymer acrylonitrile/methyl acrylate/styrene sulphonic acid (93,6/6,0/0,4) are simultaneously extruded at 90 DEG  C. through common orifices of a spinneret into a dry-spinning cell through which is passed a concurrent flow of gas at inlet temperature 300 DEG  C. The resulting composite filaments are wound up and are then drawn to eight times their original length through baths of water at 95 DEG C. followed by a cell containing steam at atmospheric pressure.  The yarn is allowed to shrink 50% in length in the steam cell and thus allow the acrylonitrile copolymer portion to relax.  In another example, the nonelastomer component is spun from a solution containing a condensation polymer of m-phenylene diamine and isophthaloyl chloride.  Specifications 461,236, 461,237, 578,079, 586,881, 597,368, 692,069, 711,279, 731,071, 849,154, 869,301 and U.S.A.
