Patent GB-609739-A (GB)
Title: Improvements relating to finishing treatment of cellulosic materials including cotton and like fibres, yarns and fabrics
IPC: D06M11/36
Filed: 1945-12-06
Abstract: Cellulosic textile materials, e.g. fabrics or yarns, are given a mechanical glaze-finish treatment to a high degree, as by passing several times through a hot calender or Schreiner, and are then subjected to a treatment with a swelling and solvent agent for the cellulose, for the purpose of removing surface roughness, the treatment being so controlled that only a surface plasticising or solution of the materials takes place, and the dissolved cellulose is re-precipitated as a thin coating on the fibres on removal or neutralization of the solvent.  The glaze-finish is rendered permanent to washing or splashing with water.  The treatment is controlled by regulating the strength of the treatment bath and adjusting the amount of reagent left on the fabric, e.g. by varying the period of immersion, the rate of passage through the reagent, and the degree of expression on leaving the treatment bath.  The treated materials may be washed before the solvent is neutralized so as to remove some of the dissolved cellulose before the re-precipitation occurs.  The solvent may be a solution of copper hydroxide in ammonia or in an alkylamine, alkylene amine, or primary aliphatic diamine, or it may be a solution of urea or thio-urea in caustic soda, or of zinc oxide in caustic soda.  In an example, mercerized bleached sateen is heavily calendered by passing it several times through a calender at 200 DEG  C. to produce a high gloss.  It is then passed through cuprammonium solution containing 13.5 grams of copper, 600 c.c. of 880 ammonia, and 20 c.c. of 80 DEG  twaddell caustic soda per litre. It is squeezed through a heavy nip, and after a short interval, is treated with acid.  A glazed chintz finish is obtained.  By increasing the strength of the bath and using suitable fabrics, stiffer finishes may be obtained.  Starches or other fillers may be incorporated in the fabrics before or after the treatment.  Instead of cuprammonium solution, a solution of copper hydroxide in ethylene diamine hydrate, propylene diamine hydrate, or di-ethylene triamine, may be used.  If desired, the swelling agent may be applied locally so as to obtain pattern effects, which may be intensified by dyeing so as to obtain two-tone or two colour effects.  Specifications 251,102, 301,392, 334,756, [all in Class 15 (ii)], 403,255, 468,633 and 469,020 are referred to.

Title: Improvements relating to the facing of concrete structures
IPC: E04G17/14
Filed: 1938-11-15
Abstract: 522,481. Moulding walls in situ. KEARY, A. F., JENKINS, E. V., and- TRUSSED CONCRETE STEEL CO., Ltd. Nov. 15, 1938, No. 33241. [Class 20 (ii)] A method of forming a design on the surface of a cast concrete wall consists in covering the inside of the shuttering 23 with a facing material 28 in a plastic condition and forming the imitation joints or design in the surface by strips 31 fixed to the surface of the shuttering and forming supports for the facing material. The strips 31 are of V or half-round section so that they may be easily withdrawn from the cast material which may be placed behind the plaster before this becomes set. The shutters are stiffened by stiffeners 22 on their' backs, connected to the shutters by angle pieces 24 and are carried in such a manner that they may be pressed outwardly from the casting position before they are raised. Uprights 15 are wedged into openings through the floors 11 and 12 and support upper transverse arms 27 which carry at their outer ends further uprights 21 to which the external shutters are secured. The uprights 21 are further supported by tackles 20 and brackets 14 secured to the uprights 15 or by pedestals positioned on the cast floor. Screw jacks 26 attached to the inner ends of cross ties 25 serve to pull the outer shutters into the correct position for casting while the inner shuttering is positioned by wedges from the internal upright 15. After the casting operation the jacks are operated and the outer shuttering with the strips is pushed outwardly from the wall surfaces, leaving the plaster as a facing for the cast concrete. The shutters may be formed of metal with rows of apertures 35 punched therein by which the moulding strips 36 are secured, the apertures not covered by the strips being covered by plyboarding. Where the ends of the shutterings abut against a column, the column may be set back behind the shutter to allow plaster to be trowelled in as a facing for the column. For churches without upper floors the uprights may be braced from a horizontal framdn,g member of the structure and the upright may carry staging for supporting workmen.
Patent GB-874865-A (GB)
Title: Production of fluorocarbons
IPC: C07C17/269
Filed: 1959-10-02
Abstract: Tetrafluoroethylene together with other fluorocarbons are prepared by heating to a temperature of at least 1500 DEG C. (a) a fluoride or fluorides of a non-metallic element of Group IV, V, VI or VII of the Periodic Table having an atomic number from 6 to 53 inclusive, and (b) one or more hydrocarbons boiling below 300 DEG C. at atmospheric pressure, and cooling the gaseous reaction product to a temperature below 500 DEG C. in less than one second.  The preferred fluorides are carbon tetrafluoride, hexafluoroethane, silicon tetrafluoride, phosphorus pentafluoride, arsenic trifluoride, sulphur tetrafluoride or sulphur hexafluoride; other fluorides such as fluorine itself and chlorine and iodine fluorides may also be used.  The hydrocarbon reactant may be a saturated or unsaturated cyclic or acyclic hydrocarbon preferably having no more than 8 carbon atoms and in which the atomic ratio of carbon to hydrogen is at least 0.3:1.  The preferred proportions of the reactants are such that there are two available fluorine atoms for each carbon atom and one available fluorine atom for each hydrogen atom in the mixture.  The reaction may be carried out essentially under the conditions described in Specifications 758,477, 760,657, 764,424, 766,323 and 766,324 which are referred to, i.e. carrying out the heating process by means of an electric arc which may be rotated magnetically to give a reaction temperature in the region of 2500-4000 DEG C. and working at a reduced pressure of 10-100 mms.  The electrodes may be made of carbon although metallic electrodes, e.g. copper or tungsten, which may be cooled by internal circulation of a cooling liquid, can be used.  The hot reaction product is preferably quenched to below 400 DEG C. in 0.001 to 0.1 seconds by passing the gas over a cooled surface or into a fluidised solid. Hydrogen fluoride which is also formed in the reaction may be removed by alkaline scrubbing.  In examples carbon tetrafluoride is heated wtih benzene, methane and acetylene and phosphorus pentafluoride with butadiene-1,3 to give mixtures containing predominantly tetrafluoroethylene with smaller amounts carbon tetrafluoride and hexafluoroethane.

A method of hot-extruding composite sections or tubes from composite billets in which a vitreous-incombustible material, for example glass, adapted to melt at least partially at the extrusion temperature whilst remaining viscous, is interposed between the billet and the billet container and between the billet and the extrusion die, the composite billets being composed of at least two bodies of different materials of which one of the bodies forms an external envelope and is of metal or metallic alloy whilst the other body or bodies is/are of pure metals, alloys or non-metallic material which are viscous or fluid at the extrusion temperature of the metal envelope. It is stated that after extrusion there is obtained a distribution inside the extruded envelope of the different interior bodies which, in cross-section, approximates to the relative positions of said bodies in the metal envelope of the starting billet. The billet may comprise a series of concentric cylinders or a billet of metal constituting the outer envelope may be provided with a series of longitudinal passages which are then filled with metallic or other material different from those of the billet metal. These passages may afterwards be closed by plugs which are secured thereto by screwing, welding or brazing. The substances which are used to fill the passages may be low melting point metals, such as aluminium, powders which are practically non- fusible, such as talc, but which are fluid at the extrusion temperature, or solid bars having a viscous stage such as glass. Metallic carbides such as tungsten carbide may also be used. Examples are given for the extrusion of a billet of steel filled with four brass rods and for the extrusion of a billet of steel filled with talc powder finely ground and rammed hard. Specification 739,499 is referred to.
