Abstract: Secondary batteries with aqueous acid solutions of lead salts as electrolytes and inert electrode base plates also contain redox systems in solution. These systems have a standard potential of from -0.1 to +1.4 V relative to a standard hydrogen reference electrode, do not form insoluble compounds with the electrolytes and are not oxidized or reduced irreversibly by the active compositions applied to the electrode base plates, within their range of operating potentials.

Abstract: The purpose is to enable double-skinned walls to be erected, with considerable mass concentration in a single element, simultaneously providing a high degree of heat insulation. The panels, which also provide sound insulation, comprise one or more load bearing layers of a fibre-reinforced plastic, one or more heat-insulating layers of a foamed plastic, and two heavy sound-deadening covering layers of high density, coated on the outside with a thin layer of plastic. The high density layers may be made of lead foil, and the fibre-reinforced plastics may have long glass-fibre reinforcement. Bonding may be effected by a melting adhesive and by adhesion-effecting foil heated above its melting-point with pressure on both sides, and a strip of plastic protruding for sealing.

Abstract: Thermoplastic molding compositions based on polybutylene terephthalate having a relative viscosity of from 1.3 to 2.0, as measured in a phenol/o-dichlorobenzene mixture at 25 DEG C, and which contain, to increase the thermo-aging stability and toughness and also to improve the processing stability, from 0.1 to 10% by weight, based on the polybutylene terephthalate, of isocyanates or isothiocyanates and/or carbodiimides and/or compounds forming isocyanate groups or isothiocyanate groups and/or carbodiimide groups.

Abstract: Thermoplastic molding compositions of polyoxymethylenes and glass fibers and containing from 0.1 to 5.0 per cent, by weight of the total weight of the mixture, of alkoxymethyl ureas having the formula R1OCH2-N-CO-N-CH2OR2 ¦¦ R3R4 where R1 and R2 are the same or different and denote straight-chain or branched-chain alkyl of from 1 to 10 carbon atoms and R3 and R4 denote hydrogen or alkyl, or R3 and R4 are joined together to form a heterocyclic ring with the adjacent ureido group.
