Abstract: Concentrated alkali metal hydroxide substantially free of alkali metal halide and other impurities is produced by the electrolysis of an alkali metal halide solution in an electrolytic cell having a dimensionally stable anode and a metal cathode separated by an electrically conductive stable selectively permeable hydrated cation ion-exchange membrane film of a fluorinated copolymer having pendant sulfonic acid groups or derivatives of such groups. The membrane film is capable of use at high temperatures and under severely corrosive chemical conditions for extended periods without degradation.

The composition is a homogeneous solution that is particularly useful where aqueous systems may create potential water pollution problems.

Abstract: Disclosed are methods for rejuvenation of oxygen electrodes which maximize the power efficiency available from such oxygen electrodes while minimizing the voltage necessary to operate such oxygen electrodes over extended periods of time. These methods include in situ and out of cell techniques using hot water washing followed by air drying and dilute acid washing followed by air drying.

Abstract: Disclosed is a method for converting a diaphragm electrolytic cell to a membrane electrolytic cell by using the standard diaphragm cell equipment and applying a membrane over top of a matting material upon the cathode surface. This method permits a manufacturer having diaphragm electrolytic cells to convert those cells to membrane electrolytic cells without significant capital expenditure to achieve the desirable characteristics of a membrane electrolytic cell.

Abstract: Novel oxygen selective electrode comprising a coating on said anode consisting of delta manganese dioxide. This outer coating on the anode may be placed on the anode electrochemically by electrolyzing an acid saline solution having dissolved therein sufficient manganous chloride. Sufficient manganese dioxide is plated on said anode when the chlorine evolution essentially ceases during electrolysis.

Abstract: Addition of sodium naphthaleneformaldehyde sulfonate to phosphate rock slurry in manufacture of phosphoric acid by the wet process permits reduction of the viscosity and/or water content of the slurry so that increased pumpability of the slurry is obtained.

Abstract: An ion exchange membrane of a fluorinated polymer which contains sulfonyl groups, wherein the sulfonyl groups on one surface of the membrane are in the form of N-monosubstituted sulfonamide groups formed from a di- or polyamine, is treated by heating at a temperature of 100.degree. to 160.degree. C. for a time of at least 15 minutes. The resulting membrane is useful as the membrane in a chloralkali electrolysis cell, and permits operation of such cells at high current efficiency over extended periods of time.

Abstract: Addition of zinc naphthaleneformaldehyde sulfonate to concrete mix improves compressive strength. This sulfonate is effective in concrete mixes prepared with Type I, II and III cements.

Abstract: Certain imidazothiazoles and thiazolopyrimidines have been found to prevent and inhibit the formation of granuloma tissue in animals. This result is accomplished by administering to the animal subject a therapeutically effective amount of a compound having the formula: ##STR1## WHEREIN R is hydrogen or methyl, R' is hydrogen, lower alkyl or thioalkyl, carboxy methyl, or phenyl; R" is lower alkyl, 2-benzofuranyl, naphthyl, phenyl, or mono- or disubstituted phenyl. The hydrated precursors of certain of these compounds as well as the acid addition and quaternary salts of both the compounds and their hydrated precursors may be employed.

Abstract: Disclosed is a cyclone for use in conjunction with electrolytic cells for separating a gas such as hydrogen from the electrolyte solution so as to significantly increase the efficiency of subsequent cells connected in series in a large bank of electrolytic cells. The subject cyclone is especially useful in a sea water hypochlorite electrolytic cell wherein the flow rate of electrolyte is in the range of 20 to 80 gallons per minute (75 to 300 liters per minute).

Abstract: Disclosed is a method for converting box form dimensionally stable anodes to the more useful and energy-saving expandable type. In one embodiment, anode box plates are cut off the anode riser at the closest point thereto. Expander springs are then attached to the anode riser and the anode box plates which have been cut into quarter panels, sized and spliced together to form new anode plates are rewelded to the expander springs. Alternatively, the method comprises the steps of cutting away only the end portions of the box anode structure and bending remaining portions of the anode screens into a spring form similar to expander springs and attaching a new pair of anode plates or screens to adjacent pairs of these newly formed springs. The anodes may then be substituted in a diaphragm-type electrolytic cell for the production of alkali metal hydroxides and halogen and the energy savings associated with the use of expandable anodes may thereby be realized.

Abstract: Since primers can be applied to metal substrates prior to subsequent operation, including metal deformation, they are often applied in coil coating operation. The potential for the removal of primer coating during metal deformation is a drawback to early coating application. There is now provided a lubricant composition particularly adapted to meet this problem. The composition comprises metallic stearate, emulsifier, titanium dioxide and Xanthomonas hydrophilic colloid, all in aqueous medium.
