Abstract: A method and adhesive system for bonding at least two elastomeric substrates together. The method comprises subjecting the substrates to a priming treatment followed by applying to the primed substrates a heat-curable polyurethane adhesive composition comprising an isocyanate-terminated prepolymer and a polyhydroxide compound. The surfaces of the substrates so treated are contacted and subjected to heat-curing to bond the substrates together.

Abstract: A percussive aid provides percussive force to aid in the treatment of Cystic Fibrosis and other pulmonary blockage diseases. The device includes a frame with a pair of reciprocating arms mounted thereto at one of their ends. The other end of the arms mount impactor cups. A spring is associated with each of the cups. A drive mechanism is carried by the frame and moves the arms through a predetermined path of travel from a first uncocked position to a second cocked position of maximum deflection wherein the spring is placed in tension when the arm is tripped.

Abstract: An animal head suitable for attachment to a stuffed animal body is molded to form a thin shell and then filled with conforming foam rubber. The head defines open jaws that can fit around a wrist of a person and an elongated tongue that can be wrapped around the wrist and secured between the upper and lower jaws to serve as a carrying handle. By making the tongue flesh tone in color and providing a red coloration on a visible portion of the tongue, a novelty effect simulating blood dripping from a bite is achieved.
