Title: Improvements in the production of potable water from saline water by distillation
IPC: C02F1/08
Filed: 1964-11-27
Abstract: 1,057,326. Distillation systems; film-type; producing potable water. SALINE WATER CONVERSION CORPORATION. Nov. 27, 1964 [June 5, 1964], No. 48289/64. Heading B1B. Potable water is produced from saline water by heating the saline water and feeding it to troughs 24 formed in the top of vertical plates 20 between each pair of which is a condenser conduit 32, bent back and forth to form a substantially solid wall, the spaces between the plates and the condensers being divided by partitions 38 into vertically-arranged cells 36. The pressure in each cell is lower than that in the cell above it. The saline water overflows from troughs 24 and flows down the plates in film-form. Some of water progressively evaporates, and the vapour condenses on the adjoining condenser 32. Each partition has a hinged connection 46 which permits a portion 48 of the partition to pivot so that its lower edge 50 can swing against and away from the surface of the adjoining plate 20. This arrangement serves to maintain a pressure differential between each of the cells 36 and at the same time permits the film of brine flowing down each plate 20 to pass from one cell to the next. The residual brine runs off the lower ends of the plates into troughs (not shown). The condensate flows down the condensers via orifices 54, and is collected in troughs. The lower part of the apparatus is connected to a vacuum pump. The water to be distilled is introduced into the lower ends of the condenser conduits. These conduits form serpentine passages so that the water flows in zig-zag paths towards the front and back of the apparatus as it slowly ascends to the conduitoutlets. The water thus acts as cooling-medium for the condensers. The preheated water is then passed through an external heater before being fed, via a de-aerator, to the troughs 24 to be distributed as films on the plates 20. The external heater may be the main condenser of a power plant. Another embodiment of multi-cell apparatus is described wherein the partions 38 are dispensed with, and nozzlechannels are provided to maintain pressuredifferentials between the cells.

Abstract: 1,178,350. Coating composition. MOBIL OIL CORP. 23 Oct.; 1968 [30 Nov., 1967], No. 50207/68. Heading C3B. [Also in Division C7] Coating compositions used in electrophoretic deposition comprise aqueous emulsions. The continuous phase consists essentially of a salt with a base, e.g. ammonia or a water-soluble amine, of an epoxy resin ester, with a long chain fatty acid, having an acid number of at least 40. The dispersed phase is a solution of an epoxy resin ester, with a long chain fatty acid, in 5-50% of its weight of a water immiscible organic solvent, e.g. toluene or a higher alcohol. The epoxy resin ester in the aqueous phase may be an ester with an unsaturated fatty acid adducted with a monoethylenically unsaturated dicarboxylic acid, e.g. maleic acid. It may also be a reaction product of a hydroxyfunctional epoxy resin partial ester with a polycarboxylic acid or an anhydride thereof, e.g. phthalic anhydride. The epoxy resin used to form both esters may be a diglycidyl ether of a bisphenol having a molecular weight of 500- 7000 and an epoxy equivalency of 1À2 to 2-0. The dispersed oil phase may also contain an aromatic hydrocarbon resin and/or a heat hardening aminoplast which is insoluble in the aqueous phase but stably dispersed therein. The aqueous phase may also contain a water miscible organic solvent, e.g. an alcohol. In an example, a diglycidyl ether of bisphenol A is esterified with tall oil fatty acid in the presence of a petroleum hydrocarbon resin dissolved in an aromatic solvent to form the ester of the oil phase. The resin of the aqueous phase is prepared by reaction of the same epoxy resin with linseed oil fatty acid and maleic anhydride in water / xylene / 2 - butoxyethanol. It is subsequently neutralized with ammonia. In preparing an emulsion for coating the above are mixed and red iron oxide and lead silicochromate added as pigments.
