    Abstract: A dampening device and method of making are provided, in which the method includes providing a first layer of a sponge rubber. An isocyanate-base prepolymer and a polyol base curing agent are combined to form a curable liquid urethane polymer. The curable liquid urethane polymer is shredded and during shredding air in the form of micro-bubbles is entrained in the curable liquid urethane polymer. The curable liquid urethane polymer is applied to form a second layer overlying the first layer and is then cured to form a tacky polyurethane cast elastomer. Micro-bubbles remain present in the tacky polyurethane cast elastomer and curing bonds the first and second layer forming a dampening device. The dampening device includes a first layer of neoprene and a second layer of a micro-bubble infused tacky polyurethane cast elastomer bonded to the first layer.

    Abstract: There is disclosed an aqueous-base coating composition containing, as essential components, finely-divided, water-dispersable: colorant, polyethylene, binder and water with sufficient of a surface active agent to form a stable suspension. The coating composition is applied as a film coating onto a polyethylene surface and the binder temporarily binds the coating to the surface until the coating can be thermally treated to incorporate the coating into the polyethylene, permanently coloring the surface. The invention also comprises a method for the preparation of the aqueous-base coating composition in which the essential components are prepared as aqueous dispersions or emulsions which are blended together to form the final coating composition.

  • Patent number: 6576337
    Abstract: A flexible rubber article such as a neck or cuff seal (1) for a drysuit is made of natural rubber in a conventional way, by dipping a former into a sensitized rubber latex. The application describes applying a thin thermoplastics layer e.g. about 25 &mgr;m thick on the surface of the natural rubber so that it can conveniently be welded to another thermoplastics component such as a hot-melt tape. The thermoplastics layer (4,5) may cover the whole or only a marginal part of the rubber article. It may be formed by dipping into a thermoplastics latex. The thermoplastics layer may cover the whole or only a margin of the rubber article. Polyurethane is one suitable material. By providing a non-tacky weldable region the invention is more convenient to use than previous proposals using adhesives.

  • Patent number: 6521329
    Abstract: A radiographic phosphor panel includes a phosphor layer that transmits actinic radiation in a range that is reflected by a transparent, polymeric multi-layer reflector used as a support. The polymeric multi-layer reflector has numerous alternating layers of at least two different polymeric materials and reflects at least 50% of actinic radiation in the range of wavelengths to which the phosphor is sensitive. The use of this polymeric multi-layer reflector in the radiographic phosphor panel provides increased photographic speed when it is used in imaging assemblies with photosensitive recording materials such as radiographic silver halide films.
