Filed: 1962-08-29
Abstract: 982,414. Reciprocating pumps. WEATHERHEAD CO. Aug. 29, 1962, No. 33179/62. Heading F1A. [Also in Division G3] In a swash plate pump in which the inlets 58 to the cylinder bores are controlled by the pistons in the cylinders and in which the cylinder block is axially slidable to vary the effective stroke of the pistons by control means which includes a pressure chamber 112 subjected to pump outlet pressure or connected to exhaust under the control of a servo valve 105, the supply of pressure liquid to the control means is through a tube 135 the bore of which is open to the outlet chamber 17 through a restricted opening 137 the other end being engageable with a member 140 having a bore connected to the servo-valve bore 104. The tube is biased by spring washers 153, 154 to the position in which it does not engage the member 140 so that on starting up the pump the liquid passes through the tube 135 and through outlets 157 to the inlet chamber. As pressure builds up and due to the unequal pressure created by the restriction 137 the tube 135 is forced into engagement with the member 140 whereby the outlet pressure is communicated to the valve bore 104 so that the control means comes into operation to control the output of the pump. Specifications 952,203, 958,973, 977,515 and 982,412 are referred to.

Title: Process for the production on textile fabrics of decorations simulating die-stamp printing
IPC: D06Q1/02
Filed: 1938-11-24
Abstract: 521,660. Treating textiles with liquids dyeing processes. HEBERLEIN & CO., AKT.-GES. Nov. 24, 1938, No. 34198. Convention date, Dec. 6, 1937. [Class 15 (ii)] A process for the production on textile fabrics, containing normally twisted yarns of vegetable origin, of wash-resistant decorations simulating die-stamp printing comprises the steps of printing the desired pattern on the fabric with an aqueous solution or dispersion of a reserve material other than one of a protein or albuminous nature, fixing the reserve in a water-insoluble condition on the fibres by drying, precipitating, or hardening, and then treating the fabric with a shrinking agent and allowing shrinking to take place. Cellulose ethers soluble in water or aqueous solutions of alkalies, e.g., methyl, ethyl, hydroxyethyl, or glycol cellulose may be used as reserve material. These compounds may be rendered insoluble on the fibres by treatment with dilute sulphuric acid. Urea-formaldehyde pre-condensates, e.g., dimethylol urea may be used. These may be rendered insoluble after printing, by heating. Dispersions of nitrocellulose varnishes in aqueous solutions may be used. Dispersion of nitrocellulose solutions containing, e.g., hexyl acetate, amyl propionate, dibutyl phthalate, tricresyl phosphate, dammar resin, ester resin, may be effected by means of sodium stearyl sulphonate, myristyl-sulphonate, or lauryl sulphonate. The aqueous emulsions obtained become waterinsoluble on drying. Aqueous dispersions of water-insoluble cellulose derivatives or vinylresins, e.g., vinyl ethers may be used, or aqueous solutions of water-soluble vinyl ethers may be employed. The reserves may be coloured or pigmented. The shrinking agent may be an alkali lye of mercerizing strength, sulphuric acid of 48-50.5‹Be, zinc chloride solution, or calcium thiocyanate solution. Thickening agents such as starch and gum tragacanth may be included in the printing composition. Specifications 231,807, 334,567, [both in Class 2 (ii)], 464,283, 482,181 and 504,666 are referred to. The Specification as open to inspection under Sect. 91 comprises also the use of non-aqueous solutions of reserve materials, including solutions of chlorinated rubber in organic solvents, and the application of the process to the treatment of fabrics containing fibres of animal origin, e.g., wool or natural silk. Wool fabrics may be shrunk by means of sodium bisulphite solution, calcium thiocyanate solution, or zinc sulphate solution, or the amino groups of the wool may be diazotized, the wool material boiled, and then shrunk by a solution of borax. Formic acid or hydrochloric acid solutions may be used for shrinking natural silk fabrics. Mixed fabrics containing cotton, hemp, jute, flax, ramie, or nettle fibres in mercerized or unmercerized state together with wool, silk, regenerated cellulose or cellulose acetate fibres, or fabrics containing wool or silk and regenerated cellulose fibres, may be treated. This subject-matter does not appear in the Specification as accepted.
