    摘要: A counter flow device for a plating apparatus including a rotary drum with its substantially half part immersed in a plating solution in a plating bath, about which a metallic strip to be plated passes in synchronism with rotation of said rotary drum and anodes spaced apart by radial gaps from the strip for causing electric current to flow between the strip and the anodes. According to the invention the counter flow device comprises a bottom nozzle arranged at a bottom of the bath and directing in a direction substantially opposite to an entering direction of the strip thereat and a top nozzle having a nozzle opening whose tip end is immersed in the proximity of a surface of the plating solution at a location where the strip leaves the plating solution, thereby ensuring uniform counter flows over entire gaps between the metallic strip and anodes to remarkably increase critical current density in plating and advantageously realize uniform plating.

    摘要: Dynamically partially cured composition comprising a peroxide-curable olefin copolymer rubber (such as EDPM) and a peroxide-decomposing olefin plastic (such as PE and PP) is improved by effecting the dynamic heat-treatment with addition of a peroxide-non-curable hydrocarbon rubber (such as PIB) and/or a mineral oil softener (process oil). The dynamic heat-treatment is preferably carried out not only in the presence of an organic peroxide but also in the presence of divinyl benzene. The elastomeric composition is thermoplastic and, with or without further blending with an olefin plastic, is processable by techniques conventionally used for thermoplastic resins. This elastomer composition and blends of the elastomer composition and olefin plastic can be used for producing foamed product in combination with decomposition type foaming agent (such as azodicarbonamide).
