Abstract: Radiation cured peelable film useful as a surgical drape or wound dressing includes a copolymer of a vinyl monomer and an acrylate capped polyurethane prepolymer. The cured film may be prepared by casting a mixture of the vinyl monomer, prepolymer and a photoinitiator onto a surface as a liquid film and exposing the liquid film to ultraviolet light.

Abstract: Superfly game apparatus includes a simulated building structure having four side walls and a roof. A scaffold is carried by each side wall and a simulated helicopter is rotatably carried by the roof. A set of playing pieces is provided each of which is configured to represent a human figure and each of which is positionable at various elevational levels along a corner of the simulated building structure. Each of the corners of the simulated building structure are given retaining elements cooperable with the playing pieces for retaining such pieces. The game apparatus also includes elements which are manually operable to impart vertical movement to the playing pieces to move the pieces upwardly along the corners of the structure.

Abstract: A composite metallic article for effecting a seal with glass, said article comprising a nickel-iron alloy core portion, a low carbon steel alloy sheath portion bonded to the core, and a uniformly thick shell portion of a glass-wetting material bonded about the sheath.

Abstract: A surfboard which is convertible from unpowered to motorized condition by the selective movement of a motor mounted in the elongated buoyant float member. Movement of the motor along the longitudinal axis of the float member does not substantially alter the floatation characteristics of the surfboard. Hand grip elements and a windshield are detachably connectable to the float member for use by the surfboard rider in a prone position during motorized operation.
