Abstract: Manufacture of an electromagnetic interference (EMI) shielding cover or other enclosure part for housing circuitry of an electronic device. The enclosure part has an exterior surface and an opposing interior surface metallized with an electrically-conductive EMI shielding layer. The layer is sprayed onto the interior surface in a molten state and is solidified to form a corrosion-resistant, self-adherent coating.

Abstract: Photocurable compositions containing a polyethylenically unsaturated resin compound and a monoethylenically unsaturated diluent are cured to form compositions containing essentially no polymerizable ethylenically unsaturated compounds by:(a) admixing with the composition at least about 0.1 weight percent, based upon the weight of the composition, of an electron-rich, aromatic promoter; and(b) exposing the admixture of (a) to a sufficient amount of radiant energy to essentially completely polymerize the ethylenically unsaturated components of the composition.For example, a composition consisting of the diacrylate of a bisphenol A and epichlorohydrin condensation adduct in a dicyclopentadiene acrylate diluent is vinyl polymerized in the presence of 1,4-dimethoxybenzene with electromagnetic radiation such that less than 0.2 percent unreacted dicyclopentadiene acrylate monomer is present in the resulting cured composition.

Abstract: Photocurable resin compositions result from a mixture of polymerizable entities containing both terminal olefinic unsaturation and oxirane groups and a bifunctional curing system capable of initiating free radical and cationic polymerization.

Abstract: A process for making a supported catalyst comprises contacting a suitable support with an aqueous solution of a metal compound and subsequently contacting said support with a reducing compound dissolved in a water immiscible organic solvent and finally heating said support to reduce the metal compound.

Abstract: The title compounds are prepared by a convenient, one-step liquid process comprising contacting with agitation, a liquid mixture comprising both:(a) an oxime, and(b) an azo compoundwith an oxidizing amount of an aqueous alkali(ne earth) metal hypohalite. For example, stirring a liquid mixture of dimethylazodicarboxylate and benzaldoxime with aqueous sodium hypochlorite produces a good yield of dimethyl-4-phenyl-2,3-dihydro-1,2,3,5-oxatriazole-2,3-dicarboxylate.

Abstract: An ultraviolet light curable resin composition comprises a mixture of entities including a polyepoxide, a partial or complete unsaturated ester of the same polyepoxide, and a partial or complete hydrolysis product of the same polyepoxide. This resin composition exhibits improved adhesion to metals.

Abstract: A photopolymerizable composition comprises: (1) a free radical polymerizable material, such as ethylenically unsaturated monomers and (2) a photoinitiator system of (a) a compound having an oxirane group in an alpha,beta-position to a carbonyl group, typical of which is 1-benzoyl-2-phenylethylene oxide and (b) a tertiary amine or other electron donor.

Abstract: A method of essentially completely polymerizing ultraviolet-curable vinyl compositions containing monofunctional acrylate diluents, the method comprising:(a) admixing with the composition at least about 1 weight percent, based upon the weight of the composition, of a polyester additive having a molecular weight not in excess of about 1,000, and(b) exposing the admixture of (a) to a sufficient amount of radiant energy to essentially completely polymerize the vinyl components of the composition.For example, a composition consisting of the diacrylate of a bisphenol A and epichlorohydrin condensation adduct in a dicyclopentadiene acrylate diluent is vinyl polymerized in the presence of ethylene diacetate with electromagnetic radiation such that less than 2 percent unreacted dicyclopentadiene acrylate monomer is present in the resulting cured composition.

Abstract: This invention relates to a vibrator which for example can be used to vibrate a tray for the purpose of conveying articles or material along the tray or alternatively can be used for vibrating articles or material where there is no requirement for conveyance in a pre-determined direction. A vibrator according to the invention has an actuator assembly which includes an actuator shaft which can rotate relative to said assembly but which is prevented from longitudinal movement relative to the assembly.

Abstract: The process of oxidizing organic compounds by dissolving the organic compound in a water-immiscible, inert organic solvent and contacting same with an aqueous hypohalite ion in the presence of a catalytic amount of a quaternary onium salt is improved by employing a primary alkyl ester as the organic solvent. For example, cyclohexylmethylamine is oxidized under mild conditions to a high yield of cyclohexylnitrile by dissolving the amine in ethyl acetate and contacting same with aqueous hypochlorite and in the presence of a catalytic amount of tetra-n-butylammonium chloride.

Abstract: Organic compounds oxidizable by hypohalite ion, such as amines, amides, primary and secondary alcohols, and alkanals are efficiently oxidized in a biphasic mixture comprising:A. a water immiscible, liquid organic phase comprising an organic compound oxidizable by hypohalite ion; withB. an aqueous phase containing hypohalite ion; andC. a catalytic amount of a quaternary ammonium salt and/or a quaternary phosphonium salt.
