Abstract: A polyurethane adhesive which is useful in bonding porous and non-porous surfaces is provided. The adhesive is especially useful in bonding windshield glass into automotive frames under a variety of environmental conditions, particularly in after market windshield replacement applications. The polyurethane includes at least one urethane prepolymer which is based on at least one thermoplastic polyol. In one embodiment, the urethane prepolymer may be formed from one or more polyisocyanates, one or more polyetherpolyols and one or more thermoplastic polyesterpolyols, wherein the prepolymer has a free isocyanate content of from about 0.6 to about 3.5 % by weight, based on the weight of the polyurethane. In another embodiment, a one-part adhesive composition is provided which includes an isocyanate-functional and thermoplastic polyurethane prepolymer having a free isocyanate content of from about 0.6 to about 3.

Abstract: A method for manufacturing a magnetotherapeutic back massager. A roller blank having a central cylindrical core circumscribed by a pair of spaced apart circular projections receives magnets in the circular projections to provide magnetic properties to the resultingly constructed magnetotherapeutic back massager. Preferably, the magnets are arranged so as to alternate polarity and a magnet-supporting strip holds the magnets together prior to and during the association of the magnets with the circular projections. The circular projections may have indentations or grooves to accommodate the magnets. Once the magnets have been associated with the circular projections, the magnets are more permanently attached by applying additional material to the circular projections so as to seal the magnets to the circular projections. The sealing material may be the same as that used to construct the roller blank, preferably latex rubber.

Abstract: The present invention is directed to a foldable and portable display system which is reconfigurable from a folded portable position to an unfolded display position and which is adapted to display a substantially continuous, unbroken graphic or display surface consisting of a plurality of individual display panels (or one or more display sheets) secured to the frames in a manner to permit the individual panels to be in edgewise abutting relationship to each other, to thereby conceal the hinged mounting frames and which are easily removable and/or replaceable for an aesthetically pleasing display.
