Patent GB-1007523-A (GB)
Title: Method and apparatus for electrically treating chemicals
IPC: H01J37/32
Filed: 1961-08-25
Abstract: Metals from an aqueous solution of a chemical having the metal ion present are plated on to steel 58 by passing the solution from a tank 56 and air from a pump 53 to a reaction zone between a hollow electrode 42 and an apertured electrode 46 which are connected to a transformer 19 supplying a radio frequency voltage sufficiently high to cause emission of ultra-violet radiation which activates the chemicals.  Metals and the solutions <PICT:1007523/C6-C7/1> from which they are derived are Al from Al2NO3.H2O; Be from Be(NO3)2.3H2O; Zr from ZrOCl2.2H2O; V from VOSO4.2H2O; Ti from K2TiO(C2O4)2.2H2O; Mo from (NH4)6Mo7O24.4H2O; Cr from Na2CrO4.4H2O. More than one metal, e.g. Ti and Zr, or Zr and Al, may be plated simultaneously by mixing the appropriate solutions.  Passage through the apparatus is stated to increase the solubility of compounds of normally low solubility, e.g. ZrK2F6, thus enabling such compounds to be used for plating.  In the case of aluminium, an organic green, red or blue dye may be added to the Al2NO3 solution to coat a steel strip continuously with coloured aluminium, which is stated to include some aluminium oxide in the coating.  Passage through the apparatus is believed to enhance the colouring ability of the dye.  Alternative forms of apparatus are described (Figs. 1-4, not shown; see Division H1).ALSO:Soluble starch derivatives such as amylodextrin are produced continuously by passing a slurry of starch and water under gravity feed, air, oxygen or ozone under pressure, and dilute hydrochloric acid under pressure to a reaction zone in an electric discharge apparatus (see Division H1) having electrodes to which is applied a radio frequency voltage sufficiently high to cause emission of ultra-violet radiation.ALSO:Olefins or compounds containing olefinic unsaturation are hydroxylized by passing air under pressure, water under gravity feed and the olefin or compound to a reaction zone in an electric discharge apparatus (see Division H1) having electrodes to which is applied a radio frequency voltage sufficiently high to cause emission of ultra-violet radiation.  Olefinic compounds which may be used are vegetable, peanut or soybean oils.ALSO:Hydrogen peroxide is prepared by passing air under pressure and water under gravity feed to a reaction zone, in an electric discharge apparatus (see Division H1), having electrodes to which is applied a radio frequency voltage sufficiently high to cause emission of ultraviolet radiation.

Title: Improvements in or relating to electrical condensers, in materials for dielectric purposes and a process of preparing the material
IPC: H01G4/22
Filed: 1926-12-06
Abstract: 262,473. British Thomson-Houston Co., Ltd., (Assignees of Boyer, S.). Dec. 4, 1925, [Convention date]. Drawings to Specification. Condensers.-Relates to materials for dielectric purposes having high dielectric constant and resistivity. Such materials are nitrobenzene, nitrotoluene, paraldehyde, acetophenone, and titanium oxide, which may be used in combination or alone as a dielectric or combined with paper, by impregnation. These materials ordinarily have, due to impurities, a high power factor and low resistivity, the latter of which may be remedied by suitable conditioning. For instance, a basic oxide, such as calcium, barium or aluminium, may be used to reduce impurities in nitrobenzene, the method for aluminium oxide being to agitate at room temperature a mixture in suitable proportions of the impure nitrobenzene and freshly ignited oxide, warming the mixture until the oxide settles out, and distilling the nitrobenzene. In this latter process, the first parts of the distillate are discarded and distillation is repeated. Resistivity also increases with time when the material is subjected to a voltage pressure, the Specification giving figures in support of this. The Specification also contains a curve showing how the power factor of a condenser having a dielectric of paper impregnated with nitrobenzene decreases with increase of electric pressure. In addition to the materials set out above, a list of twenty-eight other chemical compounds is set out in the Specification. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the invention to insulation. This subject-matter does not appear in the Specification as accepted.

Patent GB-642606-A (GB)
Title: Improvements relating to butadiene co-polymers
IPC: C08F236/04
Filed: 1947-11-21
Abstract: Butadiene admixed with an n-butene is copolymerized with a cyanoethylene in aqueous emulsion.  Useful products are obtained when up to 45 per cent of n-butene and when in addition up to nearly 40 per cent of isobutene, by weight of butadiene, is present in the mixture.  Suitable cyanoethylenes are acrylonitrile, methacrylonitrile, a  - alkoxy - acrylonitriles, a -chloracrylonitrile, methylene malonodinitrile and fumaro- and maleo-dinitriles.  The proportion of cyanoethylene is preferably not below 5 per cent of the total.  Polymerization is preferably effected in the presence of a per-compound as catalyst, e.g. potassium or ammonium persulphate, hydrogen peroxide, percarbonates, benzoyl, lauryl and crotonyl peroxides, tert.-butyl hydroperoxide, dialkyl peroxides, cumene hydro-peroxide and cyclic ether peroxides.  Other catalysts, e.g. oxygen, amine oxides, oximes, hydrazine and hydrazinium compounds, guanyl thiourea and thiobiuret, may be used. The catalysts may be activated with potassium ferricyanide, cobaltinitrites, nickeli-cyanides and iron, cobalt and nickel pyrophosphates, which may be used in conjunction with amino - carboxylic, polycarboxylic and polyhydroxy-carboxylic acids, and with reducing agents, e.g. sulphites, bisulphites, meta-bisulphites, hyposulphites and sulphinates.  Improved products result from the use of a polymerization modifier such as an alkyl mercaptan, or a di-isoalkyl xanthogen disulphide.  Suitable emulsifying agents are alkali metal soaps and salts of long chain alkyl sulphates and aliphatic sulphonates and of alkyl naphthalene sulphonic acids, and mineral oil salts of long chain aliphatic amines and of alkylolamine esters of long chain fatty acids.  The emulsifying agent may provide the reducing component for a redox system, e.g. by using a long chain aliphatic sulphonate with a small proportion of a sulphinate. Vinylidene chloride, vinyl esters, acrylic acid derivatives including esters and amides, vinyl and substituted vinyl ketones and vinyl aromatic compounds; maleic and fumaric dinitriles, dimethyl and diethyl fumarates and maleates; isoprene, piperylene, chloroprene and 2-cyanobutadiene may be added to the mixture.  The examples describe the polymerization to 60 per cent and 40 per cent conversions, adding betaphenyl naphthylamine to the latex which is coagulated with sodium chloride and acetic acid, dried and compounded with sulphur, zinc oxide, an organic p  accelerator, stearic acid and carbon black and vulcanized. Specification 613,932 is referred to.  The Provisional Specification refers broadly to the aqueous emulsion polymerization of butadiene-butene mixtures in the presence of a mono-olefinic compound which copolymerizes with butadiene more quickly than does styrene, particularly one of high dipole moment, i.e. above 1.

A pressure differential between the reservoir 18 and the container 22 is provided by arranging that a calibrated discharge valve 24 for the container 22 maintains a lower pressure than a similar valve 19 for the reservoir 18.  Some of the nozzles 21 may be excluded by means of cocks 27 in the conduits 20.  Specification 758,689 is referred to.
