Abstract: A method for removing copper contaminants from acid electroplating baths comprising adding to the bath sodium formaldehyde sulfoxylate. The presence of the sodium formaldehyde sulfoxylate overcomes overall plating haze and low current density dullness due to copper contamination in the acid tin bath.
Abstract: A watering can having a multiplicity of fluid dispensing means including a spout and a remote flexible conduit which, when not in use, is fixedly stored in appropriately recessed areas of the handle and cover of the can.
Abstract: A composite plastic material having improved shielding against electromagnetic interference is provided by injection molding a molding compound comprising elongated granules obtained by incorporating into a thermoplastic resin matrix metallized glass fibers together with carbon fibers.
Abstract: A storage and serving dish particularly constructed to retain a foodstuff of a generally unstable consistency and more particularly camembert cheese. The dish includes a dam or holder for product which is articulated and adapted to engage the severed portions of a cheese block positioned on a base member of the dish. Such dam includes means to removably fix one portion thereof to the base while another portion is freely movable to alternative positions within the circumference of the base. In addition, the freely positionable dam portion is also fixedly positioned by engagement with the dish closure when such is placed thereon.

Abstract: A process for the suspension polymerization of vinyl chloride, in the presence of a redox catalyst system consisting of a peroxyester or diacyl peroxide and an isoascorbic acid ester of a carboxylic acid.
Abstract: A procedure is provided for the production of clean, dustless particulate granules from dusty, dirty particles by treatment with a composition comprising a liquid polymeric substance, illustratively, epoxidized soybean oil, and a solid, low molecular weight polymer having a melting point in the range of about 95.degree. to 105.degree. C., illustratively, a polyethylene vinyl acetate copolymer in the proportions of from 1 part of solid polymer to 1 part of liquid polymeric substance to 2 parts of solid polymer to 1 part of liquid polymeric substance. In one modification of the procedure, the ingredients were charged to a Papenmeir mixer and the mixer was run at 1500 RPM until a temperature of 95.degree. C. was reached. The resulting product comprised clean, dustless uniform beads.
