Title: Production of cyclic organic compounds
IPC: C25B3/29
Filed: 1965-12-03
Abstract: 1,127,368. Making cyclic organic compounds electrolytically. MONSANTO CO. 3 Dec., 1965 [4 Dec., 1964], No. 51430/65. Heading C2C. [Also in Division C7] Cyclic organic compounds are made electrolytically using as starting material an organic compound containing two ethylenic groups each in α,# position relative to an electronwithdrawing group, which compound is dissolved in an aqueous salt electrolyte, e.g. a solution of an organic sulphonate, alkyl sulphate or amine or quaternary ammonium salt, the electrolysis effecting reductive hydrodimerization at the # carbon atoms forming a ring and saturating the ethylenic linkages. The electronwithdrawing groups are e.g. carboxylate, carbonamide, nitrile, phosphonium, 2-pyridine and 4-pyridine. The ethylenic groups are linked by a bivalent organic chain which is hydrocarbon except for one or more ether, thioether, imino or carboxyl groups and which may contain arylene groups as well as aliphatic hydrocarbon groups. This bivalent organic radical may consist of one or more groups of the formulµ -CR 2 -, -NR-, -O- -CO- or phenylene, there being at least one and at most 5 -CR 2 - groups, at most 2 -NR- groups, at most 2 -O- groups, at most 2 -CO- groups and at most one phenylene group, and the total number of such groups being from 1 to 8, R being hydrogen or lower alkyl and there being no -O- adjacent to an -NR-. Typical reactions are Z being the bivalent chain and Y the electronwithdrawing group. Z may also be a cyclic group yielding a double ring compound. Examples of products of the electrolysis include inter alia 2,3-dicarbethoxymethyl-1,4-dioxane and 3,4 - bis - (dicarbethoxymethyl) - 1,2,3,4 - tetrahydroquinoxaline. The electrolyte may contain at least 5%, and preferably at least 30% of ionizable salt and the anolyte and catholyte may be separated by a membrane, e.g. an ionexchange membrane or unglazed porcelain pot. To minimize polymerization of the organic compound and other undesired reactions, the pH should be maintained in the range 3-12, preferably 6-9À5. Inhibitors to prevent polymerization may be added. Cathode current densities may range from 10 to 100 or more amps per square decimeter.

Title: Bactericidal membrane for water purufier and method of making  the same
IPC: C25B13/04
Filed: 1973-11-06
Abstract: 1449239 Coated products MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 6 Nov 1973 [9 Nov 1972 (3) 14 Feb 1973] 51518/73 Heading B2E [Also in Division C1] A bactericidal membrane for a water purifier comprises a porous sheet of a water-insoluble non-woven cloth having coatings of a silver halide formed such that the surface of each fibre of the cloth in a surface layer on each side of the sheet is covered with the halide. The product may be obtained by immersing the sheet in an aqueous solution of a water-soluble silver salt, immersing the sheet further in an aqueous solution of a halide to convert the silver salt into the silver halide, washing the coated and impregnated sheet and drying. Alternatively the coatings may be formed by immersing the sheet in aqueous ammonia containing silver chloride as the ammine complex and drying. The preferred halide is the chloride. The substrate may be a canvas, non-woven cloth, asbestos cloth, glass fibre cloth and Japanese paper. A preferred non-woven cloth is formed from a synthetic fibre such as nylon, rayon, acetate, polyethylene terephthalate or other polyester, polypropylene, partially acetalformed polyvinyl alcohol and mixtures of these.

Abstract: 1471548 Removing water/ice from air ROVAC CORP 2 Dec 1974 [30 Nov 1973] 52063/74 Heading BIT [Also in Divisions F2, F3 and F4]  Air cooling and dehumidifying apparatus for motor vehicle or refrigerated rail car comprises a unitary compressor and expander 20, a filter 43 of porous material for trapping ice and/or moisture particles in the airstream from unit 20 and means for melting ice particles trapped by the filter. In the form shown, the unitary compressor and expander, which is described in Specification 1345970, draws air from within and/or without a motor vehicle. The filter 43 is a cylinder of sintered metal open at both ends and having drain holes for discharge of water. The pores are within the range 0.5 to 1000Á diameter and the filter is from 1 to 4" in diameter and 3 to 20" in length. Ice particles trapped on the inner surface of the filter 43 are melted by transmission of heat therethroungh from in-vehicle air flow through a plenum 46 which contains the filter 43. Blowers (51, 52, Fig. 2) driven by a variable speed motor pass the in-vehicle air into plenum 46 through inlets 55, 56, the mixture of in - vehicle and cooled air being discharged to the passenger compartment through vents 47. The plenum 46 is lined with glass fibre acoustically insulating material 48. The filter 43 may include by-pass openings (61, 62, Fig. 3) for the cooled air, controlled by a pair of simultaneously operable collars (63, 64) sliding on the outer surface of the filter and actuated manually or by humidity responsive means. Build up of ice particles causes a pressure increase upstream of the filter which in turn raises the temperature of the air from unit 20 causing melting of the ice. In another embodiment (Fig. 5), in-vehicle air is drawn over filter 43, whch is open at one end only, by a fan impeller (51a) within the plenum. The filter or resistance wires therein are connected to a battery via a switch (124) operable by bellows (125) open to the interior of the filter so that the switch is closed and the filter heated when pressure increases within the filter upon buildup of ice. In further embodiments (Figs. 7 to 11), the filter has heat exchange fins fixed to its outer surface, the fins being located in a duct for in-vehicle air or for air flow to the unit 20. The fins may be formed by a corrugated member (72, Fig. 7).

Title: Transmission of digital information

Abstract: 1415520 Digital television picture transmission BRITISH BROADCASTING CORP 20 March 1974 [23 Feb 1973 9 Nov 1973] 9027/73 and 52184/73 Addition to 1289015 Headings H4P and H4F In an arrangement as disclosed in parent Specification 1,289,015 where for example in a digital television picture transmission a coded equivalent signal of each picture point is compared with the previous coded equivalent and a coarse or fine adjusting signal is transmitted dependent on the difference, the arrangement is modified so that comparison is made with a combination of more than one previous equivalent signals, the combination being in any desired proportion. In one embodiment, information corresponding to odd samples is used during odd pictures and correspondingly with even samples/even pictures. Rapid movement or abrupt change continues to switch the system into coarse mode, picture elements immediately adjacent those coarsely described being updated at sending and receiving terminals by linear interpolation between those on either side. In a further modification if a new value lies nearer to the extremity of the previously sent fine range than would be defined by switching into coarse mode, then the corresponding extremity of the fine range is sent. Coarse quantization by itself can cause contouring in areas of low detail but rapid picture motion, which is undesirable. In an improvement this may be reduced partially by converting the contouring to a more random form by adding a "dither" waveform, e.g. a sine wave to the analogue signal before sampling and which may be an appreciable fraction of a coarse level. This is of particular advantage when used with a PAL or NTSC chrominance signal sampled at N/M times the sub-carrier frequency. In one arrangement N = 3, M = 1. Also with PAL/NTSC, the inputs to an interpolator can be selected to be three data inputs from current input to the coder so that the colour sub-carrier is always sampled at the same phase position. It should be arranged that the reference for the difference calculation is a combination of previous samples which has a high probability of being nearly equal to a current sample.
