Abstract: An aneurysm treatment device for in situ treatment of aneurysms comprising a collapsible member having a first shape wherein the first shape is an expanded geometric configuration, and a second shape, wherein the second shape is a collapsed configuration that is loadable into a catheter. The aneurysm treatment device is capable of returning to the first shape in the lumen of an aneurysm. Some aneurysm treatment devices comprise a spreadable portion and a projecting portion integral with the spreadable portion. The spreadable portion is capable of resting against and supporting an inner wall of an aneurysm, the projecting portion is capable of being gripped by a surgeon to facilitate insertion and positioning of the device. Other devices have relatively simple shapes and can be implanted to a site as a plurality. Treatment methods are also disclosed.

Abstract: The invention involves recycling scrap material having a thermoplastic. The invention includes a method of forming a thermoplastic pre-preg sheet for use in a subsequent molding operation. The method includes shredding a first scrap material having a thermoplastic to form fluff. The fluff has at least about 20 percent weight of thermoplastic. The method further includes sufficiently compacting the fluff into a thermoplastic state sufficient for forming the thermoplastic pre-preg sheet.

Abstract: A method for recycling materials including a significant portion of polyurethane foam includes forming the foam into a fluff of particle sized 0.25-1.0, and most preferably 0.25-0.50 inch. The material is moved to a mold and molded at an elevated temperature and pressure. Preferably, the glass transition temperature of the foam is exceeded. Other filler materials may be mixed with the fluff material. The invention recycles scrap which includes polyurethane foam, but greatly reduces the complexity of re-utilizing the scrap.

Abstract: A compressed solid produced from a feed mixture of bottom ash and a binder. The feed mixture includes about 80% to 95% by weight bottom ash, or at least about 50% by weight bottom ash in combination with other waste materials, in combination with a polyisocyanate-based binder.

Abstract: The invention relates to a method for the recycling of trim components of vehicles. The method comprises the steps of shredding manufacturing scrap and post-consumer scrap from vehicle headliners into small particles to produce fluff. This fluff is then combined with water and a binder reagent composed of either polyisocyanates, or polyisocyanates combined with various polyols. The solution of fluff, binder reagent and water are mixed, and then placed in a mold where the mixture is formed into a pre-preg sheet. Subsequently, the pre-preg sheet is subjected to compression molding at elevated temperatures to produce a finished composite trim panel. As part of the final compression molding step, a decorative coverstock can be included to produce a finished trim panel having a decorative cover.

Abstract: A transparent adhesive coating or film based on polyurethane. A polyurethane formed from at least one aliphatic or cycloaliphatic diisocyanate, at least one polyol chosen from among the polyether diols, the polycaprolactone diols, the polycarbonate diols, and the polybutadiene diols, and at least one bifunctional chain-lengthening agent containing an aromatic nucleus.

Abstract: A transparent adhesive coating or film based on polyurethane. The coating or film comprises a polurethane formed from at least one aliphatic or cycloaliphatic diisocyanate, at least one polyol chosen from among the polyether diols, the polycaprolactone diols, the polycarbonate diols, and the polybutadiene diols, and at least one chain-lengthening agent which is a product of the reduction of dimeric acid to a diol. The adhesive coating or film is employed in laminated panes of glass and/or plastic material.

Abstract: Replacement of one-third to two-thirds of the short chain diols in a polyisocyanate/polymeric polyol/short chain diol molding composition with a hydroxyalkyl-melamine provides shaped articles of increased high temperature stiffness and reduced heat sag. The hydroxyalkylmelamine is strongly catalytic for the isocyanatepolyol reaction.

Abstract: Synthetic resins having a topologically interpenetrating polymeric network comprise macrocyclic structures of chemically different, crosslinking polymers which are permanently entangled with each other. The several macrocyclic structures that are present are characterized by the absence of chemical bonds between the individual networks.
