A method of protecting surface mount capacitors from moisture and oxygen corrosion by applying a thermally curable pre-coat resin to a portion of the terminals of a capacitor and encapsulating the capacitor element(s) with a protective resin. The pre-coat resin is substantially rigid at ambient temperatures and flexible at elevated temperatures and is preferably a lactone-containing epoxy resin. The pre-coat resin may be applied to a solder coating-free portion of the terminals by brush or wiper prior to encapsulating the capacitor element(s) with the protective resin.

Protecting resin-encapsulated components

Aluminum surface mount capacitors containing one or more anode foil coupons are initially anodized in an aqueous phosphate solution in order to produce an anodic oxide film having extreme resistance to hydration and attack by corrosive anions for the purpose of producing surface mount capacitors at high yield and of high stability.

A solid electrolytic capacitor comprising a foil coated with a dielectric oxide film, wherein the coated foil has slit or cut edges, and the slit or cut edges have been reformed by anodizing the foil in an aqueous oxalic acid electrolyte, then forming the foil in an aqueous citrate electrolyte, then depolarizing the foil, and then forming the foil in an aqueous phosphate electrolyte.

Edge formation process for aluminum solid electrolytic capacitor

Edges of a slit and cut to length foil having a dielectric oxide film on at least one surface are edge formed by comprising anodizing the foil in an aqueous oxalic acid electrolyte, further edge a forming the foil in an aqueous citrate electrolyte, preferably dibasic ammonium citrate electrolyte, depolarizing the foil, and then edge forming the foil in an aqueous phosphate electrolyte, preferably an ammonium dihydrogen phosphate.

A cleaning opener for cleaning a rim of a beverage container and facilitating manual opening thereof. The inventive device includes a handle having a squeegee assembly at a first end thereof for engaging and cleaning a rim of the container to remove debris therefrom. An opening assembly extends from a second end of the handle for facilitating manual opening of a beverage can or bottle.

Perfluorinated polyethers comprising copolymers of hexafluoroacetone and epoxide and/or oxetanes are described. The perfluorinated polyethers are useful as lubricants.

Perfluorinated polyether fluids

This invention relates to perfluorinated branched ether compounds which are useful as synthetic blood substitutes and perfusion media, and for other purposes, and to emulsions which contain such compounds. A method is disclosed for direct fluorination without creating excessive unwanted byproducts. Hydrocarbon ether starting compounds used in this invention may be purchased or synthesized.
