  • Patent number: 5833782
    Abstract: A structural enclosure, box-like for many embodiments, which effectively tains an explosion, thereupon remaining virtually intact and minimizing fragmentation. The structural wall has a sandwich-like arrangement of two fiber-reinforced matrix material skins and a foam core situated between the two skins, at least one skin having fiber-reinforced high strain-to-failure viscoelastic matrix material. The core foam material selectively varies in density so as to provide appropriate rigidity or flexibility at different locations of the structural enclosure. The fiber-reinforced high strain-to-failure viscoelastic matrix material can be deformed elastically to large strains, has demonstrably high energy-absorbing characteristics, and is relatively lightweight. Upon explosive impact, the inner skin largely deforms so as to be energy-absorbent of the pressure wave caused by the explosive charge, the foam core crushes so as to also be energy-absorbent, the outer skin largely deforms, and both skins contain debris.

    Abstract: An end of a composite cylinder is formed about an end connection assembly having two longitudinally arranged pieces having a contour which prevents the withdrawal of the end connection assembly from the cylinder. The two pieces of the end connection assembly are relatively forced apart and a snap ring having a certain rest diameter is reduced in diameter and inserted into the end connection assembly to a position between the pieces. The snap ring then assumes its rest diameter positioned between the pieces, forcing them to maintain intimate contact with the inner surface of the cylinder, thus removing any residual gap from the assembly process and/or preloading the interface between the end of the composite cylinder and the end assembly prior to application of an axial load.

  • Patent number: 5783274
    Abstract: The present invention relates to a combination of an A and B adhesive reacting together through a scrim material in a laminated combination, and wherein the B adhesive has great adherence characteristics to a vinyl nitrile foam, and the A adhesive has great adherence characteristics to itself. Thus a laminate of the A adhesive/scrim/B adhesive to each side of a slit in a vinyl nitrile foam tubular insulation, with appropriate release liners covering the outside A adhesive, has been found to be particularly effective. When the release liners are removed and the A adhesives pressed together, a very strong bond is created closing the slit in the vinyl nitrile foam insulation holding the tubular vinyl nitrile foam in place on the tubular member to be insulated. Normally, this is utilized in an air conditioning application with the piping or tubes running from the compressor to the air conditioning unit, and wherein vinyl nitrile foam insulation has proven to be the best insulating material for this application.

  • Patent number: 5780132
    Abstract: A composite rubber article is obtained by joining a rubber composition based on a brominated p-methylstyrene/isobutylene copolymer to a different material such as a plastic, inorganic and metallic material through a di-, tri- or tetra-alkoxysilane compound. The copolymer is firmly joined to the different material. The invention is applicable to the manufacture of composite rubber articles such as tires, high-pressure hoses, and pneumatic springs.

  • Patent number: 5772813
    Abstract: In a process of making an absorbent article such as a sanitary napkin or a disposable diaper, hydrophilic fibers and crimped or coiled synthetic fibers are supplied in a single fiberboard to a defiberising means such as a hammermill. The process results in a homogenous and resilient blended absorbent core that can be produced using a single defiberising unit. The crimped or coiled fibers pass through the defiberising means without their two or three-dimensional structure being adversely affected at a relatively low defiberisation energy.

  • Patent number: 5771975
    Abstract: An end of a composite cylinder is formed about a multipiece end assembly having a contour which prevents the withdrawal of the end assembly from the cylinder. The pieces of the end assembly are relatively forced apart and a spacer is positioned between the parts to maintain the pieces in intimate contact with the inner surface of the cylinder thus preloading the end prior to application of an axial load or removing any residual gap from the manufacturing process. The cylinder may have end assemblies at both ends and to which may be coupled external connectors such as flange members, for construction of a marine riser.

  • Patent number: 5770286
    Abstract: A seal for use on a tubular member in post-tension construction including a cap having a tubular body and a surface extending across the of the tubular body, and a corrosion-resistant material contained within the interior area of the cap. The surface closes an end of the tubular body. The surface has a frangible area formed thereon. The surface extends transverse to a longitudinal axis of the tubular body at one end of the tubular body. The frangible area has a thickness less than a thickness of a non-frangible remainder of the surface. The cap is formed of a polymeric material. The surface is formed of a deformable polymeric material such that the non-frangible portion of the surface forms a liquid-tight seal with an outer diameter of a tendon extending through the surface. The corrosion-resistant material is contained within the cap of a suitable volume so as to fill a void in the tubular member between the inner diameter of the tubular member and the outer diameter of a tendon extending therethrough.

  • Patent number: 5766713
    Abstract: Elastomeric vehicle hoses based on ethylene, alpha-olefin, vinyl norbornene elastomeric polymers will exhibit improved cure state and improved long term heat aging. Long term heat aging is an important consideration, as vehicle lives get longer and under the hood temperatures get higher. Also, such elastomeric based hoses will have improved compression set under a wide range of service temperatures. Such excellent compression set values lead to improved sealability over a wide temperature range. Additionally, these elastomeric polymers exhibit lower compound viscosity leading generally to improved processability.
