Patent GB-847604-A (GB)
Title: Ion sources
IPC: H01J49/12
Filed: 1946-02-15
Abstract: 847,604. Ion sources. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 15, 1946 [Oct. 9, 1944], No. 4900/46. Class 39(1). In an arc type uranium ion source the amount of uranium to be ionized while supported on tungsten is limited to prevent appreciable conversion of the tungsten into an alloy melting at the arc temperature. The amount of molten uranium is less than can be retained by surface tension against gravity on the under-surface of the support. In Figs. 2 and 3, the arc is formed between a hot cathode filament 31 and a tightly coiled wire or rod anode 30. The uranium is supplied as a thin layer 34, 35 on the anode and the arc is struck in a magnetic field set up between pole-pieces 36, 37. In Fig. 5, the anode 38 is a platform of rods placed side by side and a cathode filament 41 is disposed on each side of the platform. A wire or ribbon 44 of uranium is advanced continuously or in steps through a duct 43. The anode may be a single rod and a ring or partial ring cathode may encircle the anode. In Fig. 11, the arc is struck between cathode filaments 61 and a rod anode 57 which may be advanced to bring a fresh portion into position. The uranium 72 is supplied through a feed tube 69. The structure includes a massive pole-piece 60. All supports in each of these embodiments may be liquid cooled. Several structures may be placed side by side to provide a gang type source. Reference is made to the use of the ion source in an highfrequency mass separator in which the ions are successively accelerated and retarded through a series of grid electrodes and subsequently deflected. Reference is also made to a Nier-type mass spectrometer. Specification 841,821 is referred to.

Title: Process for the continuous production of monoolefines
IPC: C07C1/30
Filed: 1965-02-05
Abstract: Olefins are obtained from a paraffin fraction in the C5-C20 range differing in carbon number by not more than 2 by halogenating to a conversion of not more than 0.5 mol per mol of hydrocarbon and continuously dehydrohalogenating under fractional distillation conditions in a packed tower, in which the packing carries an iron (II) salt catalyst, at 150-500 DEG  C. and condensing hydrocarbons in the overhead at above 150 DEG  C. and removing the hydrogen halide formed at this temperature.  Normal, iso and cyclic paraffins can be used.  The pressure should be such that the olefin product is obtained as distillate.

Abstract: 525,100. Antimony trioxide. I. G. FARBENINDUSTRIE AKT.-GES. Feb. 16, 1939, Nos. 5185 and 5186. Convention dates, Feb. 16, 1938 and June 28, 1938. [Class 1 (iii)] Antimony trioxide pigments are produced by precipitation from an antimony trifluoride solution by means of a solution of an alkali metal or ammonium hydroxide, carbonate or bicarbonate or of an organic base such as methylamine or benzylamine, and washing and drying the precipitate e.g. at a temperature of about 100‹C. The precipitation may be effected at room or at higher temperatures, e.g. at 90‹C. The alkaline compounds are preferably used in slight excess, although a slight excess. of antimony trifluoride may be used. The excess antimony trifluoride can be precipitated from the filtrate with caustic alkali or alkali carbonate solution. The filtrates may be worked up to. fluorides. The solutions employed are extremely pure ; the antimony fluoride solution can be obtained by dissolving pure antimony trioxide in pure hydrofluoric acid. The colour of the product varies with the concentration of the reacting solutions and with the temperature at which precipitation is effected. Several examples are given.

Title: Method of applying a vitreous decalcomania
IPC: C23D5/04
Filed: 1967-02-02
Abstract: 1,131,296. Vitreous decalcomania. MEYERCORD CO. 2 Feb., 1967 [10 Feb., 1966], No. 5198/67. Heading B6C. [Also in Division C1] A heat-release vitreous decalcomania which comprises a paper sheet. 1 (Fig. 1), a barrier coating 2, a wax-like heat-release material 3, an unpigmented clear resinous film 4, and a vitreous design 5 including a vitrifiable ceramic colour in a resinous film is applied to an article of glassware or chinaware by a method comprising: preheating the article; interposing between the article and the vitreous design side of the decalcomania an organic liquid material which has a partial solvent action on the resinous film containing the design 5; and pressing the vitreous design side of the decalcomania progressively into contact with the surface of the preheated article by applying pressure over a restricted area and moving this area across the decalcomania. The temporarily-adhered vitreous design may then be fired in order to obtain a permanent design on the surface. The barrier coating 2 renders one side of the paper sheet 1 less porous, and preferably comprises polyvinyl acetate although inorganic seals such as starch, casein or an alkali metal silicate may also be used. The heatrelease material 3 is preferably a normally solid high molecular weight polyethylene glycol; the clear resinous layer 4 is generally a cellulose ester or ether (e.g. ethyl cellulose) or an acrylic resin (e.g. a methacrylate polymer) in the presence of a solvent, e.g. ethylene glycol ethers or toluene and xylene fractions, and optionally a plasticizer. The vitreous design 5 comprises a pigmented vitrifiable flux dispersed in an organic liquid or binder, preferably one of the lacquers mentioned as suitable for the film 4. An optional outer clear layer 6 may also be incorporated. The pre-heated vitreous article 49 is supported between two chucks, a fixed chuck 16 and a movable chuck 24 which is movable vertically by means of operating lever 27 and which can be retained in position by heavy disc 26. The article 49 can be rotated on spindle 14 by means of cam 17 and a handle 19 on the disc 18. The forward edge of a decalcomania which has had organic liquid material applied to the design side is inserted in the nip between roller 42 and the article 49. As the disc 18 is rotated so the decalcomania is fed through the device, and the backing (parts 1 and 2) is removed from the vitreous design by means of spring finger 48, as the heat-release material 3 melts. The organic liquid material with which the decalcomania is coated before application is preferably an oil, e.g. a petroleum hydrocarbon oil, or an animal or vegetable oil. The application temperature of the article may be between 150 and 300 F.

Title: Improvements in and relating to electrical capacitors
Inventor: CHARLTON CYRIL BRADBURY
IPC: H01G4/008
Filed: 1956-02-21
Abstract: 811,332. Making electric capacitors. TELEPHONE MANUFACTURING CO. Ltd. Feb. 19, 1957 [Feb. 21, 1956], No. 5330/56. Class 83 (2). [Also in Group XXXVI] A method of making a roll-type capacitor using thermo plastic dielectric strips involves attaching to each electrode at least one metal tab to which the terminal conductors are soldered after the ends of the capacitor have been sprayed with metal. The capacitor is made by winding up two foil strips with strips of dielectric material, which may be polystyrene, so that an edge of one foil extends beyond the dielectric in one direction and an edge of the other foil extends beyond the dielectric in the other direction. The dielectric strip can be wider than the foil strip or the same width. There is attached to each foil at least one tab of a thin solderable metal such as copper, tin or tinned copper foil. When wound the capacitor may be shrunk by heat treatment, the tab may be bent over against the end face and the end sprayed with a low melting point metal such as solder. The capacitor may then be impregnated. Metal spraying ensures short connections between electrodes and tab and a secure anchorage for the terminals.
