Abstract: Provided is a system and method for protecting and restoring a surface by applying thereto a preformed polymer based film and securing the film to the surface. Particular application is found where the surface is a deck surface.

Abstract: The present invention provide a composite structure comprising an image receiving layer having an image disposed thereon and a light emitting layer, wherein said light emitting layer comprises a phosphorescent or fluorescent material capable of illuminating said image.

Abstract: Provided is a transparent recording sheet useful in producing electrophotographic images for overhead projections. The recording sheet comprises a transparent polymeric base and an imaging layer. The imaging layer comprises at least one resin and at least one transparentizer in amounts sufficient to have the imaging layer exhibit a T.sub.g in the range of from about -15 to about 50.degree. C.

Abstract: Electrosensitive recording materials (15) made with a substrate (16) of paper or plastic film; an intermediate layer (17) including a film-forming organic binder, small-sized solid particulates and large-sized solid particulates; and a thin even layer of metal (18) vacuum-deposited over the intermediate layer.

Abstract: Method and apparatus for continuous pH control of aqueous liquid systems, particularly biological and biochemical systems, by sorption of H.sup.+ and/or OH.sup.- ions with a passive ion acceptor material isolated from, but in contact with liquid of said system in a selectively permeable membrane packet. Liquid systems of interest are those with an initial pH in the range of from about 4.5 to 9.0, and the pH of the system is maintained by the invention at its initial value, or brought within, and maintained in, the range of from about 6.5 to 8.0. The ion acceptor material is selected from an inorganic, relatively water insoluble metal oxide, hydroxide, phosphate or silicate matrix which matrix is capable of maintaining a quasi-equilibrium pH state with the aqueous liquid system of interest. The matrixing metals are preferably selected from Ti, Al and B.

Abstract: Blood collection apparatus, systems and methods for minimizing the lesion of collection caused by initial high volume ratios of anticoagulant fluid to blood at the beginning of known collection processes in which blood is passed into a collection bag containing the total amount of anticoagulant fluid for the entire amount of blood to be collected. A collection bag system has a bag containing the anticoagulant fluid which is passed to a blood collection bag at a rate determined by the flow rate of the blood into the collection bag to maintain the ratio of anticoagulant to blood at a level to minimize the lesion of collection throughout the collection process. The blood collection bag is suspended by a spring from a blood bag stand and the anticoagulant bag is supported by the stand in a fixed position.
