Title: Improvements in or relating to detergent compositions in bar form
Inventor: WARD NORMAN ERNEST
IPC: C11D1/28
Filed: 1960-08-31
Abstract: A detergent composition in bar form comprises a mixture of preformed soluble soap and at least one preformed alkaline earth metal, magnesium, zinc or aluminium salt of an ester linked sulphonic acid derivative of general formula RCO.O(CH2)nSO3H, where RCO. is a C10-18 fatty acyl radical, n is 1-3, and the group (CH2)n may carry not more than one unesterified hydroxyl group.  The mixing of the soap and the salt is carried out under conditions such that exchange of cations does not take place, i.e. with insufficient water to make the mixture fluid, or if more water than this is present the mixing is achieved quickly and the product dried immediately.  The soap may be a conventional alkali metal soap, e.g. one derived from a mixture of tallow with coconut or palm kernal oil, while a suitable salt is calcium coconut acyl isothionate.  A small proportion of free saturated C10-18 fatty acid (e.g. lauric acid) may be present, as also may be perfume, colour, opacifiers, superfatting agents and germicides.

IPC: F01D1/32
Filed: 1958-09-19
Abstract: 864,466. Turbines. FUCHS, A. Sept. 19, 1958, No. 30113/58. Class 110 (3). In an hydraulic or elastic-fluid turbine in which the rotor is formed with a .helical duct having a plurality of closely-pitched turns through which the working fluid is caused to flow, thereby producing torque, a helicallywound strip is disposed within the duct and extends throughout the length thereof in the form of an Archimedian screw so as to divide the duct into two helical passages. The turbine rotor in Fig. 1 is mounted horizontally and comprises end discs 2 and 3 and a cylindrical wall 1 formed with a helical groove 9 of semicircular cross-section. The helical working fluid duct 8 is completed by securing a complementary helical pipe portion 9a of semi-circular cross-section around the cylindrical wall 1. Disposed within the helical duct 8 is a helicallyextending rod element 10 around which is wound a helical strip 11. Working fluid is supplied through a stationary duct 12a which connects with a rotary duct 12 through which fluid flows to the helical duct 8. The fluid discharges from the duct 8 through a semi-circular duct 13 which is followed by a further semi-circular duct K into the stationary, annular exhaust chamber F, the fluid discharging therefrom through outlet 27. The rotor is mounted in bearings 6, 7. A sealing device is disposed between the stationary and rotary shaft parts 12a, 12. The turbine shown in Fig. 4 is mounted vertically and is driven by water. The rotor in this case is of frusto-conical form.

IPC: F15B11/06
Filed: 1950-12-21
Abstract: 691,987. Pneumatic single-stroke apparatus. HYMATIC ENGINEERING CO., Ltd. Dec. 11, 1951 [Dec. 21, 1950], No. 30419/50. Class 8 (ii). In a double acting pneumatic jack having means for locking the piston a at the end of each stroke, both sides of the piston when in either of its locked positions are automatically vented to atmosphere. In operation and with the piston being displaced in the direction shown, compressed air from a manual valve 4 traverses an open port v in the casing t of a cam actuated valve r, and a pipe 2 to the cylinder space behind the piston a. The pressure depresses a spring-biased plunger f and a pawl carrying arm h pivoted on a pin j; the pawl q riding over a tooth of a rachet wheel m carrying a cam o which in the position shown holds open a valve s to vent the cylinder space in front of the piston through a pipe 3 and a port y in the valve casing u. The valve s when in this position closes a compressed air inlet port w. At the end of the working stroke a locking disc c rides over and momentarily depresses a stem e corresponding to the stem f to cause a pawl p to ride over a tooth on a rachet wheel k and to subsequently rotate it and a cam n which depresses the valve r to vent the space behind the piston to atmosphere through the pipe 2 and a port x. In a modification the operation of the pawl and rachet wheel mechanism is effected by rods extending through opposite ends of the cylinder and connected to spring-loaded auxiliary pistons against which catch fingers, engaging fixed locking members, abut at the ends of the stroke. In a further modification the locking and valve operating mechanisms are located externally of the cylinder.

Title: Separation of ammonia from aqueous solutions
IPC: C02F1/58
Filed: 1964-08-04
Abstract: 1,066,954. Recovery of ammonia and hydrogen sulphide from aqueous solutions. CHEVRON RESEARCH CO. Aug. 4, 1964 [July 19, 1963; May 19, 1964], No. 30482/64. Heading B1B. Ammonia and hydrogen sulphide are separated from aqueous solutions, e.g. a solution obtained by scrubbing with water a hydrorefined hydrocarbon oil, by submitting the solution to fractional distillation in a stripping column so as to remove gaseous H 2 S (free from NH 3 ) overhead and to remove a bottoms stream or a vapour side-stream containing more NH 3  than H 2 S on a weight basis; in the former case the bottoms stream is distilled in a fractionating column to obtain a overhead vapour fraction enriched in NH 3 , and this enriched vapour, or as the case may be the vapours side-stream from the stripping column, is submitted to one or more stages of partial condensation which yields NH 3  gas (free from H 2 S) and condensate, the latter being returned to the stripping column. An aqueous solution containing 4.4% (by weight) H 2 S and 3.1 % NH 3 , obtained by scrubbing a hydrocarbon oil, is passed through line 75 into drum 76 where gases and oil are separated. A major proportion of the aqueous solution withdrawn through line 79 is combined with recycled concentrated NH 3 /H 2 S solution from line 81, and the combined feed is passed through line 82, via heat exchangers 83 and 84, into column 85. A minor proportion of the non-preheated aqueous solution is introduced into column 85 through line 80. Column 85 is operated at 120 psig and a bottoms temperature of 320‹F., and water at 45‹F. is introduced into the top through line 90. Substantially pure H 2 S gas is withdrawn from the top of column 85. The stripped liquid bottoms from column 85 is cooled to 270‹F. in heat exchanger 84 and introduced through line 88 into column 92 which is operated at 60 psig and a base temperature of 307‹F. Water containing negligible quantities of H 2 S and NH 3  is discharged from the base of column 92. Vapours leaving the top of column 92 are cooled to 100‹F. in heatexchanger 101, and the condensate is collected in drum 102, from which reflux flows to columns 85 and 92 via lines 81 and 105, respectively. The vapours (predominantly NH 3 ) leaving drum 102 through line 106 are cooled by adding partially liquid NH 3  at 30‹F. through line 109, and the mixture is introduced into scrubber 108, where a high circulation of liquid is maintained by pump 112. Part of the liquid is however returned to the top of column 92 via line 114. Pure NH 3  vapour, withdrawn from the top of the scrubber, is compressed to 200 psig and then condensed in heat-exchanger 121. The liquid NH 3  is collected in drum 122, and the majority of it is withdrawn through line 124. Part of the liquid NH 3  is flashed through valve 110, and the vapour is used to cool the water in line 90.
