Abstract: Novel modified and improved beta-diketones and their use in the extraction of copper from aqueous ammoniacal solutions containing copper values, resulting from commercial processes, including, but not limited to, leaching of copper containing ores, such as sulfidic ores, or concentrates resulting from flotation of such sulfidic ores. The novel diketones are those highly sterically hindered, which may be represented by the formula I or II: ##STR1## The preferred beta-diketones of Formula [II] are selected from the group consisting of neo-alkyl beta-diketones, such as, 1-phenyl-3-neoalkyl-1,3 propanedione in which the neoalkyl group is selected from neohexyl, neoheptyl, neooctyl, neononyl, or neodecyl.

Abstract: Epoxy resins, particularly those based on bisphenol A, can constitute the principal film forming polymer component of a storage stable autodepositable composition wherein the particle size distribution of all the film forming polymers in the composition satisfies certain criteria of size distribution, and an accelerator component which is an acid, oxidizing agent or complexing agent is present in amount sufficient to provide an oxidation-reduction potential at least 100 mV more oxidizing than a standard hydrogen electrode. Such dispersions can conveniently be prepared using a two stage process in which a solution of the film forming polymers is emulsified into water to form a preliminary dispersion and this preliminary dispersion is subjected to at least one particle size refinement stage in which the preliminary dispersion is forced through a narrow aperture.

Abstract: Proposed is a method of producing alkaline-earth salts of aliphatic .beta.-keto compounds by reacting alkaline-earth hydroxides with aliphatic .beta.-ketoesters and/or .beta.-diketones in the absence of solvent to give the corresponding alkaline-earth salts. The .beta.-keto compound is added in portions to the powdered alkaline-earth hydroxide and the reaction mixture subsequently dried. Good yields are obtained of a fine-grained, light colored product.

Abstract: The joint reinforcement member for a hollow structure of an automotive vehicle has a carrier portion with an outer surface. The carrier portion has a base portion with a first extension having a first longitudinal axis and a second extension having a second longitudinal axis. The first longitudinal axis and second longitudinal axis correspond to the hollow structure. A thermally expandable adhesive layer is disposed on the outer surface of the carrier portion and substantially covers the outer surface. A method for forming the joint member includes providing a carrier having a plurality extensions extending from a base portion that correspond to the hollow structure a layer of thermally expandable adhesive materials applied to the carrier portion. The carrier portion is heated to activate the adhesive layer. The adhesive layer is cooled so that the adhesive layer is bonded to the structural member.
