  • Patent number: 10400444
    Abstract: A sealed attic insulating and roof ventilating system includes a plenum formed in part by a barrier material attached to adjacent pairs of rafters and having a radiant or reflective upper surface and a corrugated lower surface to which an insulation material may be secured. This arrangement creates an uninterrupted air chamber or ventilation plenum between the barrier material, the adjacent rafters, and the roof decking through which exterior air can circulate unimpeded from the lower vents to the upper vents of the roof. The circulation through the ventilation plenum prevents moisture from accumulating or condensing under the roof decking and warping the roof decking, which ultimately leads to deterioration of the roof decking and failure of the roof covering, and eliminates ice damming on the top surface of the roof covering.

    Abstract: A blown-film process for making a fiber-reinforced film comprises providing and melting at least one thermoplastic resin. The at least one thermoplastic resin is extruded through an extension die to form a film bubble. A plurality of fibers is introduced inside of the film bubble. The fibers are distributed inside of the film bubble. The film bubble is collapsed after introducing the plurality of fibers so as to form a fiber-reinforced film. The fiber-reinforced film has a first thermoplastic layer, a second thermoplastic layer, and a plurality of fibers dispersed therebetween. The film may be formed in a bag.

  • Patent number: 9226404
    Abstract: The present invention provides a printed circuit board (PCB) board, a core for manufacturing the PCB board and a method for manufacturing the PCB board. The PCB board is in a shape of a rectangle and comprises a fiber layer formed of interlacedly weaved fiberglasses, a metal layer affixed onto a surface of the fiber layer, and a pair of differential signal traces formed on the metal layer, wherein extending directions of the fiberglasses lie at acute angles with respect to a length direction of the rectangle, and the pair of differential signal traces extends along a width direction or the length direction of the rectangle. The PCB board can effectively reduce the possibility of the skew distortion during the transmitting process of the differential signal through adjusting the angle between the fiberglasses and the edge of the core without adjusting or redesigning the original circuit layout.

  • Patent number: 9120117
    Abstract: A diblock copolymer system that self-assembles at very low molecular weights to form very small features is described. One polymer in the block copolymer contains silicon, and the other polymer is a polylactide. The block copolymer may be synthesized by a combination of anionic and ring opening polymerization reactions. This block copolymer may form nanoporous materials that can be used as etch masks in lithographic patterning.

  • Patent number: 9109858
    Abstract: Buoyant armor for jacketed rounds includes an outer, laminate reinforced strike face having a hardness greater than 640 Brinell. The strike face is configured to strip the jacket off a projectile as it passes through the strike face and to rotate the projectile. An inner, laminate reinforced strike face is separated from the outer, laminate reinforced strike face by a spacer layer. Foam greater than 40 mm thick is disposed behind the inner strike face and is configured to disperse a round and/or its fragments and to provide buoyancy to the armor.

  • Patent number: 9102102
    Abstract: A structure comprising a plurality of plies of fiber-reinforced composite material, each ply having a ply orientation defined by a principal stiffness direction of the ply. The structure has a first region and a second region, each region comprising N1 primary plies, N4 cross plies with a ply orientation substantially perpendicular to the primary plies, N2 positive-angled bias plies with a ply orientation at a positive acute angle to the primary plies, and N3 negative-angled bias plies with a ply orientation substantially perpendicular to the positive-angled bias plies. The ply orientation of the primary plies in each region is more closely aligned with a primary axis of the structure than the cross plies or the bias plies. N1=N4 in the first region but not in the second N region, and N2=N3 in the second region but not in the first region. In each of the two regions, one ply set is balanced and the other ply set is un-balanced.
