  • Patent number: 7741387
    Abstract: A flowable material for pavement repair and maintenance comprises rounded sand coated with a polymeric surfactant to be non absorbent of water in the presence of a polymer mix which allows time for easy placement of the mix into damaged pavement. The polymeric surfactant coating creates a strong affinity between the sand and the polymer mix. The materials are chosen preferably to cause an isoviscous reaction to occur. This type of reaction is characterized by a setting phase which stabilizes the repair before a rapid change in viscosity occurs and may be further enabled by an excess of polymer to increase flowability. An excess of polymer insures that sufficient binder remains at the upper portions of the repair to provide flexible and waterproof structure while excess fluid components settle to the bottom of the repair before setting occurs to seal the surrounding pavement. The slow buildup of viscosity allows the sand to settle so that the mix becomes self-compacting.

  • Patent number: 4683929
    Abstract: A deflation-proof penumatic tire comprises a casing and a substantially void-free, preferably oil-containing elastomeric filling material. The tire casing is injected with a combination comprising a polyol, an organic polyisocyanate and water, in amounts and under conditions sufficient to produce carbon dioxide and form a polyurea-containing polyurethane elastomer in which the carbon dioxide is dissolved in the elastomer, thereby providing a substantially void-free filling material. The formulation permits the addition of a substantial amount of extender oil while retaining an acceptable level of hardness.

  • Patent number: 4630963
    Abstract: A composition and method for use in the repair of a roadway are described. A lower molecular weight hydroxyl terminated polyether polyol is reacted with an organic polyisocyanate in the presence of solvents having a specific gravity in excess of 1, and catalyzed by organic mercury and organic lead catalysts in amounts sufficient to cause the composition to gel in about thirty seconds. The reaction products are pumped or poured over an aggregate and allowed to percolate therethrough to form a flush roadway repair.

  • Patent number: 4461788
    Abstract: A method and composition are provided for preparing elastomeric polymers containing a particulate rubber filler which are useful to provide relatively thick membranes for flooring, decking, roofing or other purposes and which permit the molding of a wide variety of rubber-like goods. The composition comprises a polyol, an organic polyisocyanate, an alkaline carbon dioxide absorbent and a water carrier in amounts sufficient to form a non-foaming pourable, trowelable or sprayable composition, includes rubber particles to provide increased resiliency, economy and density, and cures internally to provide a polyurethane elastomer coating. A prepolymer may be prepared as a separate component having an extended shelf life and adapted for ultimate combination with an aqueous rubber slurry in order to facilitate simple on site mixing of the composition.

  • Patent number: 4327793
    Abstract: A solid, monolithic bicycle tire made of urethane rubber with a cured hardness of from 60 to 70 Durometer A. The tire is formed with a pair of laterally spaced bead shoulders that seat on the bead seats of the wheel rim, and is generally triangular in cross-section, with radially outwardly converging, slightly concave side walls that merge into a relatively narrow tread section. A circumferential, arch-shaped tunnel is formed in the inner side of the tire between the bead shoulders, and the material between the tunnel and the converging outer surfaces forms narrow, inwardly inclined side walls that are compressed when pressure is applied radially inwardly against the tread. The inclination of the side walls results in a substantial amplification of the deflection of the tire under impact loads, as compared to the deflection of similar-thickness side walls that are not inclined, but instead, are parallel to one another.

  • Patent number: 4310042
    Abstract: A monolithic non-pneumatic urethane tire for use on a wheel rim of the type having a pair of laterally spaced bead flanges formed with wheel rim side walls which extend upwardly from the bottom of the wheel rim is improved by providing a tire body with certain structural features and locating a tubular insert inside the tire body. The tire body has a circumferentially extending tunnel on its inside and includes side walls which converge outwardly to a thickened portion. The thickened portion forms a bead shoulder that seats on top of the bead flanges of the wheel rim and also includes a bead which extends downwardly into the wheel rim adjacent the side walls of the wheel rim. The tubular insert is a semiresilient hollow tube mounted within the tunnel of the tire body to maintain the bead portion of the tire body against the side walls of the wheel rim.

  • Patent number: 4273176
    Abstract: A solid monolithic tire for use on a wheel rim can be improved by incorporating within the tire a circumferentially extending tunnel formed on the inside of the tire body. Further, the tire body has inclined side walls that converge outwardly to form a V-shaped cross section. The apex of this V-shaped cross section forms the tread portion of the tire. Each of the side walls of the tire terminate in a thickened portion which forms a bead shoulder capable of seating on the bead flanges of the wheel rim to which the tire is mounted. Extending down through the thickened portion of either side of the tire is a bead which has a lower bead wall on the portion most distal to the thickened portion. A bead cord extends circumferentially embedded within the bead near the lower bead wall. The process by which the tire is formed allows the bead cord to be positioned in its appropriate place within the bead.

  • Patent number: 4127166
    Abstract: A solid, monolithic bicycle tire made of urethane rubber with a cured hardness of from 50 to 95 Durometer A. The tire is formed with a pair of laterally spaced bead shoulders that seat on the bead seats of the wheel rim, and has a circumferential, arch-shaped tunnel formed in the inner side of the tire between the bead shoulders. The tunnel co-operates with the channel in the bottom of the wheel rim to form an annular void, or air space, that allows the tire to collapse locally under excessive impact loads, and at the same time provides a space into which the solid urethane elastomer can be displaced under compression. Under normal riding conditions, most of the light shock loads experienced when riding on a relatively smooth road surface are absorbed by the resiliency of the urethane rubber, with only a minor amount of deflection of the arched tunnel. A severe impact causes the tunnel to collapse to a greater extent, thereby absorbing the shock load and preventing damage to the wheel rim.

  • Patent number: 4081429
    Abstract: Heat stabilization of polyurethane elastomer catalyzed with organo-metallic catalyst is accomplished by adding a minor amount of elemental sulfur or sulfur-donor material to the liquid mixture of polyol and organic polyisocyanate at the time the catalyst is added. The sulfur remains inert during the polymerization reaction, and as long as the temperature of the cured elastomer does not exceed about 200.degree. F. When the temperature of the urethane exceeds 200.degree. F, the sulfur reacts with the catalyst to form a metallic sulfide, which results in the complete neutralization, or deactivation of the catalyst. Elimination of the organo-metallic catalyst prevents depolymerization of the urethane, and the urethane therefore remains solid at high temperatures for much longer periods of time than has heretofore been possible. The amount of sulfur required to deactivate will depend upon the metal content of the organo-metallic catalyst.

  • Patent number: 4068690
    Abstract: Apparatus for filling a vehicle tire with a reactive liquid elastomer which when cured results in a flat-free tire. The apparatus provides for pre-filling the tire with air of desired pressure to properly set the tire bead on its rim and to maintain such tire pressure during the liquid filling operation. The apparatus enables removal of residual air within the tire as the tire is being filled with liquid and also indicates when the tire is completely filled with such liquid.
