Title: Colour television apparatus and method
IPC: H04N9/86
Filed: 1975-10-01
Abstract: 1507386 Television systems KODAK Ltd 30 Sept 1976 [1 Oct 1975] 40168/75 Heading H4F A television signal having a luminance and two chrominance components is modified by suppressing the chrominance components alternately in successive lines and inserting in place of the suppressed component a chosen signal modulated on a carrier having the phase of the suppressed component. As described with reference to the drawings the chosen signal is a low frequency portion of the luminance component, but it may also be false colour or stereoscopic image data or an infra-red image signal, for example. The modified signal may be added to the high frequency portion of the luminance signal to provide a signal suitable for recording on magnetic tape (Fig. 3c, not shown). The chosen signal may be recovered by first separating the inserted and the unsuppressed signals from the high frequency luminance portion and then separating these signals by suitable half-line-frequency switching in association with a one line delay.

Abstract: 1,147,749. Amino-terminated polyesters. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 4 Sept., 1967, No. 40237/67. Heading C3R. [Also in Division C5] Amino-terminated polyesters are made by reacting a carboxyl-terminated linear polyester with thionyl chloride to convert the carboxyl groups to acid chloride groups and then reacting the product with a polyamine. If polyesters containing only one terminal amino group are required, one of the two carboxyl groups of the initial polyester is first esterified with a monohydric alcohol. Specified aminoterminated polyesters are (a) polyesters of decane-1,10-dicarboxylic acid and 2-ethyl- 2-n-butylpropane-1,3-diol which contain two terminal groups comprising amino nitrogen that have been derived from N,N-dimethylpropane-1,3,diamine; (b) polyesters of sebacic acid and 2-ethyl-2-n-butylpropane-1,3-diol which contain two terminal groups comprising amino nitrogen that have been derived from tetraethylenepentamine; (c) polyesters of sebacic acid and 2-ethyl-2-n-butylpropane-1,3-diol which contain one terminal ester group derived from 3,5,5-trimethylhexanol-1 and one terminal group comprising amino nitrogen that has been derived from tetraethylenepentamine. Lubricants comprise a major proportion of a synthetic monomeric or polymeric ester lubricant and a minor proportion (e.g. 0À1 to 20% by weight) of the amino-terminated polyester (see Division C5).

Abstract: 1,120,120. Glazing. B. F. GOODRICH CO. 22 Sept., 1965 [25 Sept., 1964], No. 40400/65. Heading E1R. An extrusion comprises a U-channel 12 of rigid synthetic plastics material with flexible sealing ribs 24, 25 extending inward from the walls 17, 21 (Fig. 3). The channel base is formed as two parts 18a, 18b initially connected, but separated for use, each having teeth, which then co-act. The wall 17 extends to form a U-channel integral with the channel 12 with a separate base 14. There may be a second channel like the channel 12, both having common side walls and base, integral ribs like 24, 25 being in each. There is then one transverse inward wall from one side wall (such as 21,) with teeth on both surfaces intended to fit into a space formed by parallel walls from the other side wall (each with teeth corresponding to those on the said toothed wall), after separation of the one wall from the other two, all three being initially connected at the ends. Each form of extrusion has flexible sealing lips such as 22, 23 at the outer ends (Fig. 3) and the flexible parts are of plasticized P.V.C., the rigid material being unplasticized P.V.C. In a window sash at least one side may be separable from two adjacent ones being releasably secured thereto by a pair of right angle splines fitting into the rigid channel 11. A panel 27 in an assembly (Fig. 4) has at least one edge within a seal of two strips of rigid synthetic plastics material, one overlying each surface in the marginal regions thereof near that edge each strip having a projection 18a or 18b of rigid synthetic plastics material overlying one another with inter-engaging teeth on opposite surfaces, the ribs 22, 23 compressively engaging with the panel 27. In an assembly of two rigid panels with a seal between their adjacent edges one rigid projection has teeth on its surfaces which interengage with corresponding projections on entering the space between two walls now taking the place of the other projection.

Abstract: 1,174,699. Vacuum impregnating. WESTINGHOUSE ELECTRIC CORP. 26 Aug., 1968 [17 Oct., 1967], No. 40602/68. Heading B5A. A process for encapsulating electrical apparatus in a castable resin under vacuum conditions comprises maintaining a vacuum in the second zone of a vacuum chamber having three zones, loading a mould containing the apparatus to be encapsulted into the first zone, providing a vacuum in the first zone and transferring the mould to the second zone, returning the first zone to atmospheric pressure, filling the mould with castable resin, providing a vacuum in the third zone, transferring the mould to the third zone, returning the third zone to atmospheric pressure and unloading the mould. As shown, the vacuum chamber 12 is divided into three zones 36, 38 and 40 by gate valves 32 and 34. A conveyer system 41 comprising five independently driven sections 64, 66, 68, 70, 72 leads through the chamber 12 and the first zone 36 and the third zone 38 can be closed to the atmosphere by doors 20 and 22 pivoted about hinges 24 by cylinders 26 and carrying sections 44, 46 of the conveyer. The centre section 68 of the conveyer can be raised on a piston 80 to bring the mould 56 into contact with the resin supply nozzle 76; this conveyer section incorporating means to raise the tops of moulds of different heights to the same level and to index multi-cavity moulds containing more than one component to suitable positions for filling. The vacuum in the second zone 40 is maintained by continuous pumping and the first and third zones are connected to the same source by valves, as these two sections are never evacuated at the same time. The second zone is arranged to hold several moulds so that the electric components can be held under vacuum for some time before and after impregnating to allow the removal of as much air as possible. A control sequence for the apparatus is described.
