Title: Improvements relating to the production of ammonium sulphate
Inventor: MUNRO GEORGE IAN
IPC: C01B17/05
Filed: 1956-07-19
Abstract: Solutions of ammonium salts, obtained by removing sulphur oxides from combustion gases by means of solutions containing free ammonia, are treated in a continuous process to recover ammonium sulphate and elemental sulphur, by continuously passing the solution under pressure through two conversion vessels arranged in series.  In the first vessel the solution is heated to about 312 DEG F. and in the second stage the solution is maintained at this temperature for a sufficient time for the major part of the ammonium salts to be converted to ammonium sulphate and sulphur. The total time in the vessel is preferably 1/2 to 1 1/2 hours. In an example, the solution from a storage tank was pumped into a primary heat exchanger at a pressure of 96 lbs./sq. inch and was brought up to a temperature of 312 DEG F. in 15 minutes heat being provided by a steam supply.  The solution was then passed to a secondary heat exchanger where the temperature was maintained at 312 DEG F. for 47 minutes.  The pressure at the exit of the second exchanger was 93 lbs./sq. inch.

Title: Fluid pressure motor
IPC: F15B15/08
Filed: 1958-07-14
Abstract: 826,460. Pistons. STEINER, C. July 14, 1958, No. 22525/58. Class 122 (1). [Also in Group XXIX] A fluid-pressure motor comprises a piston 28 formed as a rack 36 between sealing-rings 37, 39 and meshing with a gear 26 on an output shaft. The chamber housing the gear and the portion of the piston chamber between the rings 37, 39 form a self-agitating lubricant reservoir. The surface of the piston opposite to the rack and the adjacent surface of its chamber are formed to provide a bearing, and felt lubricant dispersing pads 38, 40 aid lubrication of this bearing. When liquid is admitted to one end of the piston chamber to actuate the piston, the adjacent ring 37 or 39 acts as a sealing ring and the other ring 39 or 37 acts as a wiper, removing any foreign matter from the surface of the chamber. Also, the principal wear of rings 37, 39 occurs when they are in their sealing positions, and if leakage tends to occur, after long use, past a ring when in its sealing position, the leakage pressure is transmitted by the lubricant to the other ring which is in its relatively non-worn wiping position. The wiping-ring thus acts as a secondary stop or back-up. Specification 814,475, [Group XXIX], is referred to.

Title: Treatment of regenerated cellulose fabrics
IPC: D06M11/38
Filed: 1961-06-22
Abstract: Woven fabrics containing regenerated cellulose fibres having a degree of crystallinity above 50% are treated with an aqueous solution of a swelling agent for the cellulose.  The fabrics may consist wholly of the highly crystalline regenerated cellulose fibres, or may include synthetic fibres or regenerated cellulose fibres of low crystallinity.  The treatment is suitably carried out by impregnating the fabrics preferably on conventional mercerizing apparatus, with an aqueous solution containing 5-80% by weight of sodium or potassium hydroxide, sodium zincate or zinc chloride, at 15 DEG -40 DEG C. for 15-50 seconds.  The treated fabrics have less tendency to fray, show increased lustre and tensile strenght, and possess properties similar to those imparted to cotton by conventional mercerization.  The swelling treatment may be followed by a compressive shrinkage treatment.  In examples, a fabric woven entirely from regenerated cellulose fibres having a crystallinity of 53-63% are treated with 6% NaOH at 29,5 DEG C. and 18% NaoH at 39 DEG C. for 25 seconds. Specification 730,226 is referred to.
