Title: Electrodialysis device and method of operation
IPC: B01D61/52
Filed: 1959-04-13
Abstract: 882,432. Electro-dialytic cells. AMERICAN MACHINE & FOUNDRY CO. April 13, 1959 [May 13, 1958], No. 12446/59. Class 41. In the operation of an electro-dialysis unit comprising alternate concentrating and diluting cells with associated cation and anion permeable membranes, the H ion concentration controlled by passing the anolyte in which H ions are generated by the applied potential, through one or more of the concentrating cells and possibly also to the catholyte. The H ions may migrate through the permeable membrane in the anode compartment to the concentrating cell. By this transfer of H ions the precipitation of calcium and magnesium salts from hard water clogging the cell diaphragms is prevented. The flow of H ions may be controlled automatically by arranging a pH meter to monitor the acidity of the concentrating cells. A cationic membrane may be used adjacent the anode compartment through which H ions pass to the concentrating cell, but are excluded from the diluting co-product stream cells. Alternatively a part of the arolyte is diverted and passes to the concentrating cells.

Title: Improvements in or relating to the treatment of synthetic linear polyamide articles to modify their lustre, surface friction, and other properties
IPC: D06M13/21
Filed: 1940-08-05
Abstract: 543,125. Artificial filaments, films &c. resinous condensation &c. products ; treating textiles with liquids. DU PONT DE NEMOURS & CO., E. I. Aug. 5, 1940, No. 12582. Convention date, Aug. 4, 1939. [Classes 2 (ii), 2 (iii) and 15 (ii)] A. synthetic linear polyamide article in the form of a filament, pellicle, or the like is subjected to treatment with an acidic material until the tenacity is reduced by at least 2 per cent. but not more than 40 per cent. in order to obtain a reduction in lustre and to increase the surface friction. In the case of fibres the abilitv to recover from elastic stretch and the elongation properties are increased. Knitted fabrics are given a greater resistance to slipping or laddering. The polyamides used may be obtained from monoaminocarboxylic acids or their amide-forming derivatives or from diamines and dibasic carboxylic acids or their amide-forming derivatives. The acidic substance may be titanium tetrachloride, phosphorus tribromide, sulphur monochloride, thionyl chloride, sulphuric acid, hydrochloric acid, pyrosulphuryl chloride, sulphuryl chloride, chloracetyl chloride, phosphorus trichloride, or sulphamic acid. The polyamide article may be in the form of a yarn, fabric, film, bristle, sheet, or massive moulded form. In an example, yarn spun from molten polyhexamethylene adipamide is cold drawn and then passed through a solution of sulphuryl chloride in petroleum ether and then through a solution of aqueous ammonia and methanol. In other examples, yarns, fabrics, or films are treated with chloracetyl chloride in carbon tetrachloride, phosphorus trichloride in carbon tetrachloride. sulphamic acid in water, or sulphuryl chloride in petroleum ether. Yarns already delustred with titanium oxide may be subjected to the treatment. Dyed fabrics may be treated. The polyamide articles may contain plasticizers, pigments, dyes, de-lusterants, anti-oxidants, oils. and resins. The treatment may be effected at low or high temperature or pressure, and the materials may be under tension. The treatment improves the adhesion of sizes, finishes, sub-coats, or adhesives to the materials particularly films and sheets. The process may be applied to wire coated with polyamide. Instead of using simple polyamides, the articles may be made of interpolyamides or of polyamides containing ester groups, e.g. a polyamide from adipic acid, hexamethylenediamine and ethylene- or hexamethylene-glycol. Specification 461,236 is referred to. Reference has been directed by the Comptroller to Specifications 530,833, 532,674, 534,698 and 535,379.

Abstract: 572,474. Heat-treating metal articles. SHORTER PROCESS CO., Ltd., and SHORTER, A. E. Oct. 10, 1941, No. 13061. [Class 72] A hardened surface to resist battering is produced on a ferrous metal body by directing a high - temperature flame upon the surface of the body to raise the temperature of the surface above the critical point, quenching to produce a martensitic structure and then directing a reheating flame on to at least part of this surface to reheat it to below the critical point. Relative movement between the body and the heating flame &c. may be effected so that the surface is heated, quenched and reheated progressively. The heating and reheating may be carried out by different burners or by the same burner, the change from more intense to less intense heating being carried out by varying one of the factors, composition of the combustible mixture, distance of the burner from the surface or the duration of the applied heat. If a multi-jet burner is used, some of the jets may be cut out during the reheating. As applied to the heat treatment of the head of a rail W, the surface S is heated by high-temperature flame h, quenched by streams q and reheated by jets j. The flames h and streams q are supplied from a compound burner and quenching unit U supplied with gas from a pipe B and liquid from a pipe Q and the jets j from a torch T, the latter and the unit U being adjustably mounted on the arm of a clamp C supported on a carriage moved in the direction of the arrow A.
