Abstract: A package having a stretch membrane convolutely position about an unwindable wound body of strand where a tacky surface of the membrane contacts the outer layer of strands. The tacky surface also interlocks multiple layers of the membrane together.

Abstract: A reoriented insulation assembly and the method of making same is disclosed. The insulation assembly includes a plurality of mineral fiber sections, such as fibrous glass sections. Each of the sections has a machine direction, a cross direction and a loft direction. The sections are positioned in an abutting relationship with the cross direction or the machine direction of the sections defining the thickness of the insulation assembly. An exterior cover encloses the plurality of abutting sections. The reorientation of the sections places the forces generated by the fibers in a desired relationship for installation in a building.

Abstract: An aqueous coating composition comprising a polyurethane/isocyanate emulsion, a homopolymer of acrylic acid, an amino silane and water. The sizes are particularly useful for reinforcing polyamide resins (nylons).

Abstract: An underground storage tank comprises a cylindrical inner wall, a cylindrical outer wall of plastic resin and reinforcement fibers, and a layer of spacer filaments wound around the inner wall, the spacer filaments separating the inner and outer walls, and the spacer filaments being at least partially surrounded by voids to enable liquids to flow along the filaments.

Abstract: The present invention provides a fiberglass composite which possesses outstanding armor properties. This ballistic resistant composite material employs high strength magnesia aluminosilicate glass fibers and phenol formaldehyde condensation product as the matrix resin. The composite is produced from sheet molding compound using little or no solvent.

Abstract: Apparatus particularly adapted for applying foamed treating liquor to a flat width of a traveling non-woven textile substrate includes a longitudinal tubular foam distribution nozzle one side of which has a plurality of closely-spaced staggered apertures for engaging and applying pressurized foam widthwise across the substrate and a driven drum opposed to the nozzle engaging widthwise the opposite side of the substrate for imparting traveling movement to the substrate. The drum and nozzle cooperate to compress the substrate therebetween in covering relation over the apertures to prevent lateral escape of the foam therefrom and to confine the emission of foam therethrough, thereby to uniformly control foam application across the substrate width as it travels by the nozzle. Limited contact of the apparatus with the substrate prevents frictional pulling and structural damage thereto. The drum is perforated for escape of the air component of the foam and to enhance foam penetration of the substrate.
