    摘要: A coated fastener includes a coating comprised of one-hundred percent dry solids which is virtually free of solvent emissions when applied and during curing, covers substantially the entire exterior of the fastener, provides a protective coating to the fastener against corrosion, enables the fastener to be adhered to at least one other fastener, and provides increased holding power of the fastener after the fastener is driven into a desired surface.

    摘要: A steel fastener has an elongate shank, an enlarged head formed at one end of the shank, and a generally pointed tip formed at the other end of the shank. A grooved portion of the shank is formed with helical grooves defining helical ribs and with annular grooves defining annular rings. The shank has a cylindrical portion between the grooved portion and the tip and a cylindrical portion between the grooved portion and the head. Each of the annular grooves has a root where deepest and each of the annular rings has a crest where largest. The roots define an imaginary cone diverging toward the tip. The crests define an imaginary cone converging toward the tip. The shank has an exterior surface coated with a polymeric coating, which is formed from an aqueous composition containing a water-based acrylic resin and a water-based polyurethane resin. A zinc layer and a chromate conversion layer are provided between the polymeric coating and the exterior surface of the shank.

    摘要: A screen for anchoring a fastener to a hollow block or brick wall which includes an elongate tubular plastic screen member having first and second opposite ends and a uniform diameter along its length. The first end is formed substantially into a frusto-conical shape that includes at least a portion thereof where the mesh of the screen is closed off. At least one reinforcement member is formed along the length of the elongate screen member that enables the elongate screen member to be inserted within a first aperture formed in a first wall of a hollow block and maintain the desired stiffness of the tubular screen member so that it can extend across an interior of the hollow block for blind insertion into a second aperture formed in a second opposite wall of the hollow block.

    摘要: A method of reinforcing or retrofitting building roof structures against hurricane-force winds which does not require removal of part or all of the roof. The improved method includes directing a thin stream of a liquid polymer foam adhesive under pressure upwardly along the intersections of the rafters or support members and the roof panels, preferably on both sides of the support members. The foam adhesive then creams and foams, forming polymer foam adhesive gussets which firmly adhere to the adjacent surfaces of the support members and roof panels. This method increases the pull-off strength of a roof about seven fold and is able to withstand hurricane-force winds.

    摘要: In a railroad track comprising a railroad rail having a lower flange, a railroad tie made from concrete, and a polyurethane pad mounted between the lower flange of the railroad rail and an upper surface of the railroad tie, a particulate layer is interposed between the polyurethane pad and the railroad tie and comprises particles bonded to the polyurethane pad. Preferably, the bonded particles are polycarbonate, acrylic, or nylon particles, either granules or fibers. Alternatively, the bonded particles are particles of quartz, silica sand, silicon carbide, or aluminum oxide. An adhesive layer is interposed between the polyurethane pad and the railroad tie, comprises a methacrylate ester composition, and is bonded to particles among the bonded particles and to the railroad tie, whereby the polyurethane pad and the railroad tie are bonded to one another via the particulate and adhesive layers.
