Title: Improvements in or relating to thermal radiation detectors
IPC: G01J5/12
Filed: 1959-10-07
Abstract: 881,596. Thermo-couples. ALBISWERK ZURICH A.G. Oct. 7, 1959 [Oct. 7, 1958], No. 34031/59. Class 37. A thermal radiation detector comprises a plurality of thermo-couples, the hot junctions of which are disposed along a plurality of axes in a common plane, at least one of the elements forming each thermo-couple consisting of a wire whose longitudinal axis at the hot junction is perpendicular to the said common plane. As shown, Fig. 2, a plurality of wires 2 of e.g. bismuth, are pushed into perforations in a plate 1 of insulating material and secured thereto by an insulating layer 3 sprayed on to one side of the plate. A layer 4 of a good electrically conductive but poor thermally conductive material, e.g. antimony, is vapour deposited over the ends of the wires 2 which protrude slightly from the other side of the plate, and a filtering and protecting layer 5 is deposited on layer 4. In a modification, the wires 2 pass through the layer 4 and slightly protrude beyond it, the ends of the wires receiving incident radiation and conducting heat to the junctions. Fig. 3 shows a plurality of insulated wires 7 clamped between two halves of an insulating plate 6, the bare ends of the wires being aligned in one plane and conductive and filtering layers being deposited thereon. In Fig. 5, discrete thermocouples formed by wires of bismuth 14 and antimony 15 joined by intermediate layers 16 of gold are mounted in a plate 17 of insulating material. The heat-receiving areas of the thermo-couples may be arranged according to a system of rectangular or polar co-ordinates, and may vary in size or density with their distance from the centre of the plate.

Patent GB-1390970-A (GB)
Title: Process for the production of polymers in particulate form
IPC: C08J3/14
Filed: 1972-07-24
Abstract: 1390970 Production of particulate polymers from solution; segmented copolymers ROHM GmbH 24 July 1972 [22 July 1971] 34518/72 Headings C3G and C3P  A process for the production of polymers in particulate form comprises dispersing in a volatile non-polar organic liquid a solution of the polymer in a polar solvent, the organic liquid being a non-solvent for the polymer and immiscible with the polar solvent, removing substantially all the polar solvent from the dispersion by distillation and separating the resulting particulate polymer from the organic liquid, the removal of solvent being carried out at least partly in the presence of a dispersing agent. The process is particularly applicable to aqueous solutions of polymers comprising polar monomers, such as acidic or basic monomers and their salts, or amides, methylol amides, hydroxyesters or nitriles of unsaturated acids. The removal of the solvent is carried out by distillation of the solvent itself or of an azeotrope with the organic liquid. The dispersing agent is preferably a graft or block copolymer having one or more polar segments and one or more non-polar segments. In examples the organic liquid is a tetrachloroethylene-n-heptane mixture and the polymer solution is polyacrylic acid or a copolymer of acrylic and methacrylic acids trimethyl - # - methacryloxyethylammonium chloride and methyl methacrylate, or acrylonitrile and methyl methacrylate, in water, or a copolymer of methyl methacrylate, butyl acrylate and sodium acrylate in a waterisopropanol mixture.  Block copolymers useful as the dispersing agent are obtained by a one-stage polymerization reaction in an aqueous solution of a soluble monomer comprising a dissolved initiator and suspended droplets of an insoluble comonomer. For example butyl acrylate or methacrylate may be thus copolymerized with trimethyl-#- methacryloxyethylammonium chloride or sodium acrylate in the presence of 4,4<SP>1</SP>-azo-bis-4- cyanopentanoic acid and a copolymer of dimethylaminoethyl methacylate and butyl methacrylate or sodium methacrylate and styrene. Graft copolymers are obtained by heating an azo-group containing copolymer with the grafting monomer. The backbone polymer may be one prepared from an azo-group containing monomer directly, e.g. a copolymer of butyl methacrylate or 2-hydroxypropyl acrylate and a monomer of formula or the azo group may be introduced by treating the preformed polymer with a suitable reagent, e.g. treating a decyl methacrylate-isopropenyl- 4,4-dimethyloxazolone-5 copolymer with azobis-isobutyric acid hydrazide. The grafting monomer may be trimethyl-#-methacryloxyethylammonium chloride, acrylamide, methacrylic acid or a mixture of ethyl acrylate and 2-hydroxypropyl acrylate.

[Classes 123 (ii) and 123 (iii)] A forced-flow boiler has a number of parallel connected long small-bore tubes arranged horizontally along the walls of a vertical combustion chamber 1 and of a parallel flue containing an economizer 202a, 202b and a superheater 242. The tubes are connected to a vertical supply header 204 and pass completely around the bottom part of the combustion chamber and flue, and then they are bent upwards and arranged in flat loops across the flue with portions extending around the sides of the combustion chamber and between the combustion chamber and the flue. They are then again bent upwards to form superposed flat coils extending about half way across the flue and with portions around the combustion chamber, and finally they are arranged around and over the top of the chamber. A superheater 242 is arranged in the part of the flue not occupied by tube coils. Above the superheater and tube coils are economizer sections 202a, 202b each extending half way across the flue and separated by a wall L, and an economizer section 202 extending across the full width of the flue. Dampers M, N above the two passes formed by the partition L control the flow of gases over the superheater.

Title: Process for the production of finely divided particles of silica
IPC: C01B33/193
Filed: 1958-10-30
Abstract: Acid-precipitated, finely-divided, filterable silica containing cationic impurities is purified by adding a small amount, e.g. 0,02 to 0,5 grms/litre, of a metal or ammonium salt to an aqueous slurry of the silica and treating the slurry with an ion exchange resin, preferably in amount sufficient to reduce the pH of the slurry to below 6, e.g. 2-4.  Salts may be K2SO4, KNO3, KBr, NaNO3, Na2SO4, NaCl, Na oxalate, Na acetate, NH4Cl, (NH4)2SO4, BaCl2, BaSO4, CaSO4, CaCl2, AlCl3, AlF3, Al2(SO4)3, Al acetate, MgSO4, MgCl2, or MgBr2. The silica may be prepared from alkali metal silicate and at least a stoichiometric amount of a weak acid having a dissociation constant below 1 X 10-4 for the first H and gaseous in the anhydrous state, e.g. CO2, SO2, or H2S.  The precipitated SiO2 flocs, having a surface area 25-400 sq. m./grm., and actual particle size 0,1-10m , and containing at least 90% SiO2 on the anhydrous basis, are filtered off and washed to yield a filter cake containing 12-20% solids.  This filter cake after addition of the salt, is mixed with granular, e.g. 10-100 mesh, iron exchange resin, in amount at least 1 lb. resin/lb. SiO2 and water, if necessary, to maintain not less than 12% SiO2 in the slurry.  Resins may be sulphonated polystyrene, styrene-vinyl benzene copolymer, phenol-formaldehyde resin, lignin, or peat, or amino resins.  The mixture of slurry and resin is allowed to stand with agitation, and the resin is separated by settling, decantation, or centrifuging, or a combination of these separations.  Preferably, a portion of the silica slurry is separated from the resin and then the remainder, e.g. 0,25-25%, is separated.  The silica may be stabilized before the resin treatment by heating in an aqueous medium at above 60 DEG C. for at least 30 mins., or by drying at 100 DEG C. or above, e.g. 120 DEG -300 DEG C. for 10 secs.-25 mins. and then redispersing.  Specification 774,586 is referred to.
