Abstract: Cell and process for the electrowinning of metals from fused salt baths, especially aluminum from cryolite-alumina (5), featuring a packed cathode bed (7) of loose refractory materials resistant to the molten metal and disposed at the base of the cell. The packed cathode bed allows the molten metal to be continuously drained off so that the anode-cathode distance may be reduced.

Abstract: A substantially non-consumable anode used in the production of aluminium from a cryolite-based fused bath containing alumina consists of a sintered self-sustaining ceramic oxide body of spinel structure which is made conductive by selective partial substitution, the introduction of non-stoichiometry or by doping so as to maintain the impurities in the produced aluminium at low levels. Preferred materials are partially-substituted nickel ferrite spinels.

Abstract: Normally solid copolymers of a fluorinated vinyl monomer and a perfluorinated vinyl compound having a carboxyl and/or sulfonyl group attached directly to the perfluorinated vinyl group or indirectly through an alkyl or ether linkage have been found to be soluble in low molecular weight polymers of perhalogenated alkyl ethers, low molecular weight polymers of perhalogenated alkyls and perfluoro kerosenes, each of said solvent materials having boiling points between about 200 C and 350 C. The copolymeric material dissolved in accordance with the instant invention can readily be resolidified by solvent removal and hydrolyzed or converted to the salt form to become a cation exchange material having an equivalent weight in the range of 1000 to 1600. When these cation exchange materials in the salt form become damaged or contaminated during operation, for example in an electro-chemical cell, they may now be reclaimed rather than discarded. The process involves conversion of the salt form of the cation exchanger to the precursor sulfonyl fluoride, carbonyl fluoride, sulfonate ester, or carboxylate ester form followed by dissolution in one of the solvents mentioned above. Dissolved impurities are then removed, e.g., by filtration, and the purified precursor cation exchange material in dissolved state may be shaped into the desired form by solvent removal and hydrolyzed back to the purified cation exchange polymeric material.

Abstract: An amphoteric water-in-oil self-inverting polymer emulsion is prepared which contains a copolymer of (1) a nonionic vinyl monomer and (2) an amphoteric vinyl monomer or a terpolymer of (1) a nonionic vinyl monomer, (2) an anionic vinyl monomer and (3) a cationic vinyl monomer in the aqueous phase, a hydrocarbon oil for the oil phase, a water-in-oil emulsifying agent and an inverting surfactant. An example of a copolymer is a copolymer of (1) a nonionic vinyl monomer such as acrylamide or methacrylamide and (2) an amphoteric vinyl monomer such as a reaction product of dimethylaminoethyl methacrylate and monochloroacetic acid. An example of a terpolymer is a terpolymer of (1) a nonionic vinyl monomer such as acrylamide or methacrylamid, (2) an anionic vinyl monomer such as sodium acrylate and (3) a cationic vinyl monomer such as a triethyl ammonium ethyl methacrylate methosulfate salt. The emulsion is useful in papermaking, treatment of sewage and industrial wastes, drilling muds and secondary and tertiary recovery of petroleum by water flooding.

Abstract: Des particules catalytiques avec un materiau de support inerte, resistant a la corrosion, sont pourvues d'un catalyseur finement disperse dans une matrice d'un polymere insoluble electriquement conducteur forme in situ sur chaque particule du materiau de support inerte. Les particules inertes de support sont activees catalytiquement par: (a) mouillage des particules avec une solution contenant un compose precurseur inorganique pour le catalyseur et un compose precurseur organique pour la matrice polymere insoluble, (b) sechage des particules, et (c) traitement thermique des particules pour convertir les precurseurs en catalyseurs que l'on obtient sous forme finement dispersee dans la matrice polymere. Une electrode, p.ex. une anode a degagement d'oxygene, est produite soit en fixant les particules catalytiques sur une base d'electrode, p.ex. du plomb, soit en consolidant les particules catalytiques dans un corps d'electrode poreux.

Abstract: A catalytic electrode has an electrically conductive substrate such as titanium with a coating comprising a platinum-group metal catalyst finely dispersed in a matrix consisting of a semi-conducting polymer formed in situ on the substrate. The catalyst may be a platinum-group metal oxide such as iridium oxide formed in situ together with the semi-conducting polymer by the application of a uniform liquid mixture followed by a controlled heat treatment. The semi-conducting polymer is preferably formed from polyacrylonitrile, polybenzimidazo-pyrrolone or an adamantane based polybenzoxazole.
