  • Patent number: 11097500
    Abstract: In a method for producing a hull wall of a fiber composite sandwich component, shaped bodies of extruded polystyrene hard foam are enveloped with an envelope of fiber composite material with fibers oriented at least bidirectionally. The enveloped shaped bodies have a shape for forming a hull wall and are placed next to each other in a vacuum injection structure on a lower cover layer of fiber composite material. An upper cover layer of fiber composite material is placed on top of the enveloped shaped bodies and the vacuum injection structure is sealed. Matrix material is introduced and distributed in the vacuum injection structure until the fiber composite material of the envelopes and of the upper and lower cover layers is impregnated completely with the matrix material. The matrix material is cured and the fiber composite sandwich component of the hull wall is removed from the vacuum injection structure.

  • Patent number: 7338915
    Abstract: This invention provides a method of making single-wall carbon nanotubes by laser vaporizing a mixture of carbon and one or more Group VIII transition metals. Single-wall carbon nanotubes preferentially form in the vapor and the one or more Group VIII transition metals catalyzed growth of the single-wall carbon nanotubes. In one embodiment of the invention, one or more single-wall carbon nanotubes are fixed in a high temperature zone so that the one or more Group VIII transition metals catalyze further growth of the single-wall carbon nanotube that is maintained in the high temperature zone. In another embodiment, two separate laser pulses are utilized with the second pulse timed to be absorbed by the vapor created by the first pulse.

  • Publication number: 20070243784
    Abstract: A portable and stowable quilting wall has generally rectangular body composed of a smooth backing sheet sewn peripherally to a mating front sheet of heavy nap felt. A top hem mounts spaced pieces of hook fasteners interspersed with holes. A bottom hem confines a heavy rod, while the backing sheet mounts strips of loop fasteners that are spaced to engage the hook fasteners when the wall is rolled up on itself to retain the quilting wall in a rolled-up condition for easy movement and storage. The felt nap releasably engages pieces of quilt pieces placed and retains them in both rolled-up and unrolled conditions, without the use of added adhesive or mechanical fasteners. The holes in the top hem receive hooks to hang the unrolled sheet against a wall or door, while the rod maintains the quilting wall flat against a vertical surface.

  • Patent number: 7179761
    Abstract: A bituminous water vapor retarder is disclosed of the type which can be used under concrete slabs in contact with soil or granular fill. The vapor barrier is a multi-ply weather coated permanently bonded semi-flexible bituminous core board composed of the homogeneous high melt point bituminous material in combination with an exclusive core suspended midpoint in the board. This core is sealed under heat and pressure between liners of asphalt and impregnated felt and a glass mat liner. An asphalt weather coat is applied to the glass mat liner and covered with a polyethylene anti-stick sheet.

  • Patent number: 7169719
    Abstract: The invented product is a fleecebacked laminate that is suitable as a single-ply fleecebacked roofing membrane. The laminate consists of the following: 1) a thermoplastic reinforced planar sheet, 2) a needle punched fleece formed on both sides of the thermoplastic reinforced planar sheet, and 3) a thermoplastic polymeric layer extruded onto one side of the fleece. The fleece is formed by needle punching fibers through the reinforced planar sheet. The reinforced planar sheet serves as a common supporting base the resulting two-side fleece. The thermoplastic polymeric layer is embedded with one side of the fleece fibers. The thermoplastic polymeric layer serves as the top layer of the roofing membrane, and the second side of exposed fleece serves as a felt. The thermoplastic polymeric layer is preferably comprised of an extruded PVC substrate, compounded to have excellent weather resistance, printability and to be nonflammable. The fleece fibers are preferably composed of polyester.

  • Patent number: 6936329
    Abstract: A fastener-free composite roofing product comprising a roofing material and an interply material attached to the roofing material, wherein the interply material includes an adhesive coating on one side. The interply material is attached adjacent to an edge of the roofing material to permit a major portion of the interply material to be folded away from the roofing material for application to a roof. The adhesive is effective to secure the roofing product to the roof without the use of nails or other fasteners. The roofing material may be a roofing shingle or roll roofing, and the interply material is comprised of a water resistant material.

  • Patent number: 6846759
    Abstract: A method of making a soft, well cushioned, fabric suitable for use in an automotive interior, furniture and upholstery. The fabric which is formed by depositing a coating of a high temperature adhesive having a viscosity of 6×104 to 75×104 centipoise at its application temperature on one surface of a felt cloth followed by laying down a layer of a second material on top of the adhesive-coated surface of the felt cloth to form a composite. The composite is then passed through a hot pinch point to firmly bond the second layer to the felt cloth.

  • Patent number: 6846545
    Abstract: A material to reduce the effects of trauma received from the impact of a projectile. One embodiment is a needle-punched, non-woven material including at least one type of ballistic fibers selected and oriented to provide a cushioning effect and maintain a high compressive restitution constant. A percentage of the fibers are oriented with at least their ends lying approximately perpendicular to the fabric plane and/or oriented to lie in a waveform generally along or parallel to the fabric plane. This enables the ends of the fibers lying perpendicular to the fabric plane to cushion the impact from the projectile by dissipating energy through compressional resistance, and the fibers along the fabric plane to reduce energy through dispersal along fiber lines, thereby reducing the trauma resulting from an impact.

  • Publication number: 20040219846
    Abstract: A composite sheet biasable into a tubular shape to form a sleeve for isolating or protecting elongated items is disclosed. The sheet has a reflective surface formed by a metal foil layer overlying a flexible polymer layer having a metalized surface. A biasable polymer netting layer is positioned overlying the flexible layer opposite the metalized surface. The netting layer is formed of elongated members that define interstices. A damping layer of non-woven material is positioned adjacent to the netting layer. An adhesive layer is positioned between the flexible layer and the netting layer to bond the netting layer and the damping layer to the flexible layer. Biasing is effected by the elongated members of the netting layer which are stiffer in the circumferential direction around the sleeve to provide radial stiffness.
