Patent GB-826479-A (GB)
Title: Improvements in or relating to the dyeing of human
Filed: 1956-04-21
Abstract: A hair-dyeing composition comprises an aqueous solution or dispersion of a coloured substance which has an affinity for human hair, and an organic solvent for the coloured substance which is insoluble or only slightly soluble in water, the solubility of the coloured substance in the organic solvent at the temperature of dyeing being greater than its solubility in water.  A "coloured substance" is defined as a dyestuff or a water-insoluble coloured organic compound.  When the organic solvent is insoluble in water an aqueous emulsion containing the coloured substance may be used.  The composition may contain also a solvent miscible with both water and the organic solvent, e.g. when the organic solvent is "Alphanol" (Registered Trade Mark) isopropyl alcohol may be used as the additional solvent.  The composition may be applied directly to the hair or it may be formed on the hair by (1) applying to the hair the organic solvent either alone or as a solution or emulsion in water or an organic liquid, e.g. ethyl alcohol, and subsequently applying an aqueous solution or dispersion of the coloured substance; (2) applying the coloured substance to the hair in the form of an aqueous solution or dispersion and subsequently applying the organic solvent either directly or as a solution or emulsion in water or in an organic solvent; or (3) applying the organic solvent and coloured substance to the hair simultaneously and then treating with water.  Specified organic solvents are amyl alcohol, benzyl alcohol and amyl lactate or, according to the Provisional Specification, n-butanol, ethyl acetate, thymol, acridine or cyclohexanone.  Specified coloured substances include Carbolan Brilliant Blue 2R, Rhodamine B, Chlorazol Fast Red F, and Orasol Red B.

Abstract: Tetrafluoroethylene polymers are made by polymerizing tetrafluoroethylene alone or admixed with up to 25 per cent by weight of one or more ethylenically unsaturated monomers, in an aqueous acidic medium, in the presence of a water-soluble ionizable dispersing agent, a catalytic amount of a water-soluble peroxy-compound of a saturated aliphatic dibasic acid, and a quantity of iron not exceeding 10 parts per million by weight of the water present.  The polymerization may be effected continuously or batchwise, and the polymerizable mixture may contain a saturated hydrocarbon containing more than 12 carbon atoms which is liquid under the polymerization conditions, and also a telomerizing agent. Other monomers mentioned are ethylene, methyl methacrylate, styrene, vinyl fluoride, chlorotrifluoroethylene, hexafluoropropylene, perfluorobutadiene, hexafluorocyclobutene, perfluorisobutylene, trifluorethylene and perfluoroheptene-1.  Specified dispersing agents are potassium hexadecafluorononanoate, ammonium and potassium eicosafluoroundecanoate, ammonium and sodium dodecafluoroheptanoate, ammonium hexadecafluorononanoate, ammonium perfluorocaprylate, sodium perfluorocaproate and ammonium perfluorocaprylate.  Other suitable dispersing agents are those described in Specification 689,400.  The peroxy compound may be disuccinic acid peroxide, diglutaric acid peroxide, or peroxy compounds described in Specification 631,570. The saturated hydrocarbon may be octadecane, eicosane, tetradecane, cetane, white mineral spirit, paraffin waxes of suitable melting point, or one of the hydrocarbons described in Specification 673,443. Telomerizing agents mentioned are methanol, ethanol, and chloroform. The product of the process before coagulation is an aqueous colloidal dispersion which may be used for casting films, for coating and impregnating textiles, glass fabric, ceramics, metal, or wood.  The polymer isolated from the dispersion may be made, e.g. moulded, into sheets, rods, tubes, or into fibres or filaments, or used for coating wires and fabrics.

Title: Improvements in and connected with the operating mechanism for working the doors of self-discharging receptacles
IPC: B61D7/26
Filed: 1921-05-05
Abstract: 164,315. Krupp Akt.-Ges., F. June 3, 1920, [Convention date]. Hopper wagons.-In a self-discharging receptacle, the operating mechanism contains two crank gearings positively connected to each other, one crank-arm of which has passed its dead position toward the end of the operating movement, the other being in front of its dead position. The doors A, B are hinged at c', c', and are operated through a handle M loose on the shaft G<2>, lugs m<1>, m<2>, on the cross-piece attached to the handle engaging a. pin g<4> on a crank-arm G<3> when opening or closing the doors. The arm G of the bell-crank lever is connected to the door through link F, cranks E<2>, E, and link D. Similarly the other arm G<1> of the bell-crank lever is connected to the door B through link H, cranks J<2>, J, and link K. When closing the doors by means of the handle M, the lug m<1> engages the pin g<4> on the crank-arm G<3> and revolves it in the direction of the arrow x thereby actuating the bell-crank lever and its connecting-links and cranks. Toward the end of the movement the toggle joint formed by the link K and crank J passes its position of dead centre before the toggle joint formed by link D and crank E. In the closed position of the doors further movement of the toggles is prevented by stops c<3> bearing against cranks E<2>, J<2>, and the bell-crank lever and its connecting-links have passed their position of dead centre. The handle M is retained in th,e closed position by a stoppin N. When opening the doors, free movement of the handle M occurs until the lug m<2> engages the stop g<4>, the bell-crank lever is then revolved until the toggles are broken, the weight of the load opening the doors, further action of the doors being independent of the handle M.
