Abstract: 371,476. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, and EWEN, H. A., Gray Walls, Priest Lane, Shenfield, Essex. Jan.28, 1931, No. 2813. [Class 40 (v).] A frame aerial 1 for a submarine D is adapted to be lowered flush with the deck when out of use, the supporting arms 6 being simultaneously collapsed umbrella.wise within the tubular support 2. The structure is swung laterally about a pivot 3 by rack-and-pinion gear 4, 5.

Title: A process for the production of sulphuric acids of aliphatic amino-ethers of high molecular weight
IPC: C07C309/09
Filed: 1934-01-27
Abstract: Sulphonic acids of aliphatic amino ethers which are stated to be wetting, washing and emulsifying agents in the form of their salts with alkalies or organic bases, are prepared by acylating a sulphonic acid of an aliphatic amino-ether or a salt thereof with a fatty acid containing at least ten carbon atoms or a resin acid or a chloride thereof.  The free sulphonic acids are stated to be carbonizing agents.  Sulphonic acids of aliphatic amino ethers may be prepared by treating with ammonia or a primary amine the halogenated ether sulphonic acids obtained by reacting dihalogen aliphatic ethers with alkali or ammonium sulphite.  In an example, b  : b <1>-dichlordiethylether is treated with alcoholic sodium sulphite, and the resulting product treated with methylamine and acylated with lauric acid chloride.  The latter may be replaced by abietic acid chloride, and ethylamine or aniline may be used instead of methylamine.  The use of oleic, palmitic and linoleic acids is mentioned.  The Specification as open to inspection under Sect. 91 comprises also the use of naphthenic, myristic, and oleostearic acids and the dihalogenated ethers obtained from an aldehyde, e.g. formaldehyde and hydrochloric acid, the condensation products of halogenated alcohols with aldehydes and hydrochloric acid and ethers of halogen hydrins of polyhydric alcohols. Dichlordimethylether, chlormethyl-b -chlorethylether, methylether of b  : b :glycerine dichlorhydrin and alkylether of pentaerythrite di- or trichlorhydrin are specified starting materials.

Title: Process for preparing olefin interpolymers
Inventor: KHELGHATIAN HABET MISSAK
IPC: C08F6/02
Filed: 1964-01-27
Abstract: Catalyst residues are removed from a copolymer of at least two alpha-olefins prepared in a hydrocarbon diluent and a catalyst comprising (a) a halide or acetylacetonate of vanadium and (b) a metal alkyl, metal hydride, metal borohydride, or alkyl metal halide, by contacting a solution of the copolymer with an alkali metal hydroxide, removing the solvent by stripping with steam, and separating the interpolymer from the resulting water solution of metal compounds.  The amount of the hydroxide is sufficient in conjunction with the steam to convert the metallic components of the catalyst residues into a water soluble state. A wetting agent such as an alkyl aryl polyether may be added before steam-stripping.  In Example I a copolymer of ethylene and propylene was purified of catalyst residues from vanadyl trichloride and triisobutyl aluminium by agitating the polymerizate with an aqueous solution of NaOH at 120 DEG  F., adding the above mentioned wetting agent and stripping with steam.  In Example II, the procedure is the same except that the catalyst residues removed are derived from vanadyl trichloride and diethyl aluminium chloride.

Heading H1K A semi-conductor thermoelectric element is inserted in the current path between a superconductor and a normal conductor so that the resulting Peltier effect acts to reduce heat transfer between the normal conductor and the superconductor; the arrangement is suitable for magnets or transformers with superconductor windings. Fig. 1 shows a direct current arrangement in which a P-type thermoelectric element 6 and an N-type thermoelectric element 7 are connected between the ends of copper conductors 1 and 2 and superconductor 3. With current flowing as indicated, the Peltier effect is such that the superconductor junctions tend to be cooled and the copper junctions tend to be heated so that heat transfer between the superconductor and copper elements is reduced. An alternative arrangement is described for A.C. applications in which there is a parallel arrangement of a P-type and an N-type thermoelectric element at each end, each element being in series with an appropriately poled rectifier so that current flow through the correct thermoelectric element to provide the desired heat characteristics. In a further modification, a number of thermoelectric elements are connected in series with copper portions at each end, each thermoelectric element being associated with a separate cooling arrangement. The thermoelectric element may consist of bismuth-antimony telluride, bismuth telluride, bismuth selenide, bismuth-selenium telluride, lead selenide, lead telluride or bismuth antimonide (88% Bi, 12% SB). Coolants for the superconductor chamber may consist of vaporizing hydrogen, air, carbon dioxide, ethylene, Xenon or ammonia. The superconductor may consist of Nb 3 Sn, NbZr, vanadium-gallium or vanadium-silicon.

[Also in  Division H2] A circuit arrangement for converting a D.C. voltage of one value to a D.C. voltage of another value which can be variable over a range of the original voltage comprises a semi-conductor switching device the conductive periods of which are variable and further comprises means whereby energy can be returned to the supply through the circuit arrangement without the use of the semiconductor switching device. A D.C. to D.C. converter comprises a supply such as a battery 40 supplying a lead, shown as an inverter 75 and an electric motor 16, the amplitude of the lead voltage at conductors 15, 15A being controlled by a thyristor 12, a centre tapped choke 23 and an energy sink in the form of a filter network 14A, 14B. The conductive periods of the thyristor 12 are controlled by a control unit 57 which provides gating signals-on a conductor 84 when the thyristor 12 is to be rendered conductive and gating signals on a conductor 35 when a second thyristor 30 is to be rendered conductive, the function of this latter thyristor being to cause extinction of the thyristor 12 by the discharge of a capacitor 33 through the portion 27 of the choke 23. The operation of this capacitor is enhanced by the provision of a diode 56. Diodes 45, 46 and on autotransformer 48, 50 form the means by which energy may be returned to the battery 40 from the motor 16 when the motor is acting as a generator under regenerative conditions. If required the system may be made responsive to the output voltage, the output current and the input voltage by the provision of signals 65, 70, 73 respectively. These signals are supplied to the control unit 57 and together with a set value control 57A, are effective to control the gating signals 34, 35 to the thyristors 12, 30. A plurality of converters may be connected in parallel to the D.C. supply only one of which may be provided with the regenerative elements 45, 46, 48, 50. With such an arrangement the converter so provided may form the energy source for all the converters during regeneration should the D.C.. supply fail.
