Abstract: 1,274,747. Improved crease-resistance of cellulosic fibres. INSTITUT TEXTILE DE FRANCE. 13 Aug., 1969 [14 Aug., 1968], No. 40496/69. Heading D1P. A method for improving the crease-resistance properties of cellulosic fibrous materials comprises i) swelling the fibres with an aqueous solution of an organic or inorganic base, the strength of the solution being such that the swelling is effected in the interfibrillar spaces of the fibre but not within the fibrils ii) replacing the swelling solution by a series of further liquids, the first being miscible with water and the last being miscible with the liquid preceeding it in the series and iii) incorporating into the last liquid a relatively elastic substance having an initial modulus of elasticity lower than that of cellulose. The elastic substance or precursors thereof may be dissolved in said last liquid, which may contain a monomeric elastomer precursor, an initiator and a catalyst polymerisation being effected until an elastomer is formed within the interfibrillar spaces. Prior to the inclusion of the monomeric precursor active polymerisation sites or regions of unsaturated bonding may be formed on the walls of the fibrils. Alternatively a prepolymer of the elastic substance may be incorporated in an emulsion form and may be subsequently coagulated. An elastomer may also be formed by including a solution of a first monomer e.g. an isocyanate in the last inclusion liquid followed by the "padding-in" of a solution of a second monomer e.g. a diol and subsequent polycondensation of the two monomers. The aqueous swelling solutions may be of an organic base e.g. a fatty amine, ethanolamine or morpholine or an inorganic base e.g. solutions of less than 8% by wt. sodium hydroxide, 15% by wt. potassium hydroxide, or 6% by wt. lithium hydroxide. Caesium hydroxide solutions may also be used. The inclusion liquid series may include a) an organic solvent series soluble in water and in hydrophobic solvents and b) a hydrophobic solvent.

Filed: 1962-10-29
Abstract: 962,298. Gas turbine plant. A. P. PEDRICK. Oct. 29, 1962, No. 40772/62. Addition to 944,195. Heading F1G. The present invention relates to improvements in or modifications of the invention set forth in Claim 1 of the parent Specification. According to a first aspect, the first turbine rotor is provided with cooling means which are automatically operable upon rotation of the rotor. According to a second aspect means are provided for causing the gases discharging from the first turbine rotor to pass direct to atmosphere without acting on the separate useful power turbine rotor. According to a third aspect the pistons of the engine are provided at their radially inner ends with sealing means, the sealing means being so arranged that the sealing pressure against the bores of the cylinders in which the pistons are disposed is varied authomatically in response to the pressure within the cylinder. The first rotor R is shown in Fig. 3(A), this rotor being provided with ducts C, D by which air and fuel mixture is directed into the engine cylinders as the rotor rotates and with ducts H by which combustion gases are directed from the engine cylinders on to the power turbine blades, the action of the gases on the ducts H serving to drive the rotor R. The rotor R also carries the cam plates by which the pistons are caused to reciprocate within the cylinders. The vanes forming the ducts H are hollow as shown in Fig. 3(C) there being holes in the side walls of the vanes to permit flow of cooling liquid therethrough. Series of tubes 4 extend across the rotor and cooling air is caused to flow therethrough, the heated liquid from the hollow vanes being circulated outside the tubes whereby the heat is transferred to the air. In accordance with the second aspect of the invention ports are formed in the rotor of the useful power turbine in line with the gas discharge from the ducts H in the rotor R. The ports are associated with closure members which are spring loaded so that at zero or low speeds of the power turbine rotor, the gases pass through the ports and discharge to atmosphere without acting on the power turbine. At higher speeds the closure members are moved outwardly under centrifugal force against the action of the springs, the by-pass ports are therefore closed and the gases then act to drive the power turbine rotor. In accordance with the third aspect of the invention the pistons are provided at their inner ends with sealing means each of which comprises a plug member having an axial bore which communicates with radial bores by which pressure beneath the piston is communicated to the inner surface of a cup-shaped sealing member carried by the piston in engagement with the cylinder wall. The cup-shaped member is thus caused to bear more tightly against the cylinder as the compression beneath the piston increases.
