Title: Improvements in or relating to the treatment of textile fabrics
IPC: D06M15/17
Filed: 1939-07-31
Abstract: 532,343. Treating textile fabrics. HERCULES POWDER CO. July 31, 1939, Nos. 22185 and 22186. Convention dates, Aug. 5, 1938, and June 23,1939. [Class 15 (ii)] A substantially permanent finish is imparted to textile fabrics by treating them with a medium containing a polyhydric alcohol ester of a rosin, said ester having a melting point within the range of 25‹C.-100‹C., and preferably within the range of 35 C.-70‹C. The ester may be applied as a solution in an organic solvent, or as an aqueous emulsion, and any of the usual textile finishing materials, such as starches, gums, talc and softeners, may be present. After treatment, excess treating liquid may be removed from the fabric, and the latter dried at elevated temperature. In preparing the rosin esters, wood rosin, gum rosin, hydrogenated rosin or the acids from such rosins, e.g. abietic acid, pimaric acid and sapinic acid may be employed, and specified polyhydric alcohols for esterifying the rosins are ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, glycerol, diglycerol, or mixtures thereof. In the preparation of emulsions of the rosin esters, emulsifying agents such as sodium oleate, sodium lauryl sulphate, triethanolamine stearate, Duponol, Nekal 3A, or Aresklene 400, may be used, and the emulsions may be stabilized by homogenization or by the addition of such stabilizing agents as sulphonated castor oil, methyl cellulose, gelatin or gum arabic. Numerous examples are given.

Title: Improved manufacture of chloride of lime
IPC: C01B11/06
Filed: 1931-08-05
Abstract: In the production of anhydrous bleaching powder by treating hydrated lime with chlorine, chlorination is interrupted before reaction is complete and preferably when two-thirds of the lime has been chlorinated, a part of the water formed by the reaction, say, four-fifths, is removed by the application of high vacuum, chlorination is then completed, and the product finally dehydrated in vacuo.  By this procedure formation of lumps is avoided and a dense product obtained.  The various steps of the process may be carried out in a single apparatus fitted with agitating means, both chlorination steps and the intermediate removal of water taking place at 40 DEG  C., and final dehydration at 46-48 DEG  C.

Abstract: 531,737. Closures for collapsable tubes. STEATIT VERKAUFSGES. AKT.-GES. July 31, 1939, No. 22212. Convention date, Aug. 3, 1938. [Class 125 (iii)] A cap b is screwed on the neck a<SP>1</SP> of a collapsable tube a and a valve c is seated in the top of the cap while a valve d, to open inwardly, is seated at the bottom of the neck a<SP>1</SP>. The valves are on a common stem e and a spring h, tending to keep the valve c closed, is arranged between a cross bar f and a shoulder on the stem e. When the cap is partly unscrewed both valves are closed, but when the cap is screwed home as shown in Fig. 2, the additional valve d is open. As pressure is applied to the tube the contents pass into the neck a<SP>1</SP> and lift the valve c from its seat and both valves remain partly open to permit discharge. With release of the pressure from the tube a the spring h closes the valve c. Ribs i at the lower end of the valve stem slide in grooves in the inner surface of the tube neck, and act as guides during movement of the valves.

Abstract: 988,041. Hydro-pneumatic shock absorbers. OPEE Ltd. June 28, 1961 [June 28, 1960], No. 22630/60. Heading F2S. [Also in Division B7] A hydro-pneumatic buffer or draw gear comprises an annular plate 6, Figs. 1, 2, which may float radially in a recess 7 in a plate 8 screwed to the base 4 of the plunger, so that as full closure of the buffer is approached the plate 6 slides and centres over the pin and reduces the aperture area to substantially zero. In order to permit this movement of the plate the pressure on both of its faces is equalized by the provision of an annular groove or grooves 12, Fig. 4, which communicate through holes 11 with the pressure chamber. The plate 6 may be retained substantially concentric with the housing 8 by a corrugated peripheral leaf spring, Figs. 7 and 8 (not shown). In a modification the rear face of the plate 6 or the base 4 against which the plate abuts may be chamfered to reduce the pressure difference. The small axial movement permitted to the plate allows it to act as a one-way valve during recoil and permit fluid to return to the pressure chamber via ducts 8a, the plate being acted upon by an annular end spring. In another modification the end spring is provided with radial and bent fingers which retain the plate both radially and axially. Specifications 703,855, 721,222 and 808,931 are referred to.
