IPC: H01H29/28
Filed: 1925-11-18
Abstract: 243,712. British Thomson-Houston Co., Ltd., (Assignees of Vickery, H. W.). Nov. 28, 1924, [Convention date]. Supplying and controlling consuming devices.- A two-way conducting-liquid switch comprises chambers 10, 11 connected by a tube 12 and having pockets 13, 14 and dams 15, 16 so arranged that whem the gas in the chamber 10 is heated by a filament 21 the mercury is forced out of the chamber 10 into the chamber 11 into the position shown in the Figure so as to connect a terminal 19 with a terminal 20 instead of with a terminal 18. The switch is shown applied to a lighting system in which a source 23 is connected to the lights 25 through the terminals 19, 20 so long as the filaments 21 is kept heated by the source. Should the source 23, fail, mercury will flow from the chamber 11 to the chamber 10, breaking the circuit through the terminals 19, 20 but closing another circuit from a battery 27 to the lights 25 through the terminals 18, 19.

Title: Liquid coating compositions
IPC: C09D133/10
Filed: 1958-09-11
Abstract: A liquid coating composition is prepared by mixing a clear dispersion of a fatty acid-treated colloidal hydrous iron oxide pigment in a volatile organic liquid with a clear solution of a polymer of methyl methacrylate having a relative viscosity of 1,117-1,196 (measured as a 0,5% solution in ethylene dichloride at 25 DEG C.) the weight of the polymer being at least equal to the weight of the pigment and, based on the total weight of the total fluid mix, the pigment constituting up to 15% and non-volatile solids constituting up to 35%, to provide a clear fluid mixture which, as freshly prepared, yields a cloudy film when applied as a coating and dried, and then ripening the mixture whereby it yields a clear film when applied as a coating and dried.  Methylmethacrylate polymers specified are the monopolymers and copolymers with minor amounts of other monomers such as acrylic and methacrylic acids, methyl acrylate, C2-C4 alkyl acrylates and methacrylates, glycidyl methacrylate and styrene, and mixtures of such polymers.  The iron oxide pigments used are those obtained by treating colloidal hydrous iron oxide with fatty acids such as caprylic, lauric, myristic, palmitic and naphthenic acids and castor oil, tall oil and coconut oil acids.  The solution of the polymer and dispersion of the pigment are made with the aid of solvents such as benzene, toluene, xylene, acetone, methyl ethyl ketone, ethyl acetate and ethylene glycol monoethyl ether.  Other specified ingredients are amine-treated bentonite, aluminium paste, phthalocyanine green, nitrocellulose and benzyl butyl phthalate. The ripening of the compositions can be effected by storing at room temperature, but it is hastened by agitation and/or warming to a moderately elevated temperature.  Specifications 499,790 and 807,895 are referred to.ALSO:A fatty acid-treated colloidal hydrous iron oxide pigment is prepared from a slurry of hydrous iron oxide in water by adding thereto a solution of coconut oil acids in xylene, and heating at 50-60 DEG C. with agitation for 1 hour.  Water is removed from the mixture leaving a clear dispersion of the treated iron oxide in xylene.  Specifications 499,790 and 807,895 are referred to.

Abstract: 781,775. Detecting radio-activated cleaning apparatus in pipe lines. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 6, 1955 [Oct. 11, 1954], No. 29196/54. Class 40 (3). Pipe lines may be scoured internally by cleaning apparatus having brushes 26, a lead screening pot 1a, a radio-active source 8a contained in a lead-filled piston 7a, and a pressureoperated oil-filled bellows 15a which moves the piston 7a out of the pot 1a against a returnspring 18a when the apparatus is working in a pipe line. When the apparatus is inoperative and subject only to normal pressure the spring maintains the piston 7a within the screening pot 1a, but when the apparatus is in use and subjected to the high pressure in a pipe line the oil in the bellows is forced into the cylinder 21 and moves the piston 7a out of the pot 1a so that the position of the apparatus may be detected by a radiation monitor outside the pipe. Oil 27 in the cylinder 21 prevents the spring 18a from being completely compressed, and a pressure balance is always maintained inside and outside the apparatus.

Abstract: 921,755. Coating by dipping. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Aug. 14, 1961 [Aug. 16, 1960], No. 29264/61. Class 82. An electrical conductor such as a copper wire 1 is simultaneously annealed and coated with a metal by transporting the conductor vertically through an annealing chamber 2 containing a protective gas into a heated coating bath 3 containing molten metal while the conductor is being electrically heated, such as by the passage of electric current therethrough as supplied via a variable transformer 18 from a source 17, the temperatures to which the conductor and molten metal are heated being adjusted so that application of flux is unnecessary. The molten metal may be electrically heated from a resistance 14 supplied from an additional source 15 and adjusted by a regulator 13. In the example for tinning copper wire, the wire passes downwards from the chamber 2 through guiding devices 11 and protection tubes 9 and 10, the base of the latter being perforated, into the bath 3, then through a guide 16 for smoothing the coating on the wire, and protection tube 4 into a cooling tank 5 filled with water. The portion of the wire between the bath 3 and tank 5 may also be heated, but to a temperature lower than that passing through the annealing chamber and coating bath. The difference between the annealing temperature of the copper wire and the temperature of the molten tin is preferably 100 to 150 C.

Abstract: 1500269 Nitroguanidine SUPPLY MINISTER OF 13 Feb 1953 [13 Dec 1951] 29281/51 Heading C2C Nitroguanidine is made by mixing guanidine nitrate and oleum, in a ratio equivalent to substantially 1À1 parts of 20% oleum to one part by weight of guanidine nitrate, at about 25‹ C., with the addition of recirculated spent acid mother liquor to form a slurry of precipitated bisulphate of nitroguanidine. The mixture is passed to a separation stage in which spent acid mother liquor is separated from the solid product of nitroguanidine bisulphate and part of the separated acid is recirculated to the nitration stage to maintain the slurry in a flowable condition. The remainder of the separated acid is passed to a dilution stage to which the separated nitroguanidine bisulphate is also passed. The mixture is diluted at the dilution stage with wash water recirculated from the final washing stage to form dilute sulphuric acid and liberate nitroguanidine which is separated and washed. Specification 572,931 is referred to.
