Abstract: 321,699. Auer, L., and Strachovsky, N. June 13, 1928. Emulsions, making. - Organic isocolloids containing acids of high molecular weight, such as vegetable or animal oils, resins, fats, naphthenic acids or these bodies or rubber after treatment with modifying agents such as those described in Specifications 287,943, 289,414, [both in Class 91, Oils &c.], 289,415; and 321,689, [Class 91, Oils &c.], are vulcanized by heating with sulphur or a sulphurizing compound with or without accelerators, fillers, or pigments in a current of saturated or superheated steam. Organic solvents such as benzene, xylene, tricresyl phosphate may be added. The steam, which may be applied! before or after sulphurization, may be passed over or through the mixture, and the condensed water produced in desired amount by regulating the temperature and pressure forms an emulsion with the vulcanized product. Emulsifying agents may be added. In an example, linseed oil, which has been modified by heating in vacuo with sodium sulphide, tetraethyluram disulphide, zinc oxide, and sulphur, is heated in an autoclave in a current of steam. After cooling, the product is mixed with an aqueous solution of casein, ammonia, and ammonium oleate. Specification 18536/00, [Class 70, Indiarubber &c.], is referred to.

Abstract: 981,630. Producing fresh water from saline water. BURNS & ROE Inc. May 7, 1962 [May 12, 1961], No. 17390/62. Heading B1B. Saline water at a temperature of 65 ‹F. is pumped from pipe 11 into the surface condenser 14 of a steam-turbine 15, where the saline water functions as a coolant and is heated, e.g. to 96 ‹F. ; the warm saline water then flows to tower 17 where it is distributed from channels 31 so that it flows, in the form of several films, down the sides of a parallel assembly of vertical plates 32, while atmospheric air, e.g. at a wet bulb temperature of 62À5 ‹F., is drawn upwards through the spaces betwen the plates, and becomes saturated with moisture. The saturated air is drawn up frustoconical duct 18 into tower 20 which also contains a parallel assembly of vertical plates 32. The upward flow of air through the apparatus is effected by fans 34. Fresh water at a temperature of about 70 ‹F., supplied through pipe 21, is distributed over the upper ends of the plates of tower 20, and flows down the sides of the plates in the form of films. The moisture is condensed from the upwardlyflowing air as it is cooled by direct contact with the downwardly-flowing films of cool fresh water. The air is then discharged from the top of the apparatus. The fresh water, i.e. coolant + condensate, collecting in the troughs 35 of tower 20, is led out through pipe 22; some of it is withdrawn from the system as product through pipe 24, and the remainder is passed, via pipe 25, to heat-exchanger 26 wherein it is cooled by saline water introduced into heatexchanger through pipe 29. The cooled fresh water is then recirculated to tower 20 through pipe 21. The saline water running off the lower ends of plates 32 is collected in troughs 35, and is discharged from the apparatus through pipe 19. A three-stage apparatus, each stage comprising two towers as above, is also described.
