  • Patent number: 9505164
    Abstract: Helically reinforced, flexible tubing or hose is formed from continuously extruded thermoplastic material helically circumferentially wound at a wrapping station around an array of bearing-supported rods that are concurrently but individually turned and are canted relative to an imaginary center axis. The tubing or hose being formed has a continuous reinforcing rib helically wound therearound and continuously integrally connected thereto. The positions of the rods are progressively altered during formation of at least a contiguous portion of the length of tubing or hose, causing the resulting tubing or hose portion to exhibit a progressive continuous change in diametrical size. The resulting tubing or hose may be transversely severed at intervals along its length, and may be flattened to form cuffs near where severed.

  • Patent number: 8262825
    Abstract: Composite tubes may be fabricated by filament winding a layer of resin impregnated carbon fiber with a near-axial fiber orientation over a mandrel and over end-fittings. Bands of resin-impregnated fibers are then wound circumferentially around this near-axial layer in a position that coincides with a circumferential groove in the underlying end-fittings. The ends of the near-axial layer are folded back over the bands, resulting in a double layer of intact near-axial fibers locked into the groove on the end-fittings by the bands of intact circumferential fibers. Testing has shown this arrangement to be effective for introducing very high axial loads onto the composite tube.

    Abstract: A non-fibrous ultra high molecular weight polyethylene tape having a width of 1-inch or greater and a modulus of 1,400 grams per denier or greater. The non-fibrous UHMWPE tape is obtained by compression molding ultrahigh molecular weight polyethylene powder at a temperature below its melting point and then drawing and stretching the entire resultant compression molded UHMWPE sheet, with no slitting or splitting of the sheet, at a draw ratio of at least 100:1. The UHMWPE tape can be produced in weights of 6,000 to 90,000 denier or greater. The UHMWPE tape of the present invention minimizes the effect of stress concentrators that are prevalent with fibers and thereby enables the tape to be drawn at much higher draw ratios than is possible with fibrous UHMWPE. When used in ballistics panels, the high modulus high molecular weight polyethylene tape of the present invention improves ballistic performance by providing enhanced dissipation of the impact energy of a projectile.

Examples of handles that may benefit from a custom grip include baseball bats, hockey sticks, pool sticks, lacrosse sticks, tennis racquets, golf clubs and the like. The molding of the grip may be a combined synergy of thermal energy resulting from friction and electrical current flowing through a material that hardens in response to both thermal and electrical stimulus. This hardening process may occur while undergoing the dynamics that the end product experiences when in use by the intended user. The resulting handle may be both uniquely matched to the user's hands as well as his or her style of use.

The strike face portion includes a plurality of interleaved layers of non-fibrous ultra high molecular weight polyethylene tape. The backing portion includes a plurality of interleaved layers of cross-plied fibers of ultra high molecular weight polyethylene. The entire stack of interleaved layers is compressed at high temperature and pressure to form a ballistic resistant panel having a strike face on one side. It has been found that ballistic resistance increases as the weight ratio of the strike face portion with respect to the backing portion decreases. A composite panel having a strike face Tensylon tape with at most 40% of the total weight of the panel exhibits improved ballistic resistance properties as compared to a monolithic structure of strictly interleaved layers of cross-plied high modulus fibers.

  • Publication number: 20100170590
    Abstract: A piping element (1) comprises at least one flow pipe (4), an insulator (3) arranged outside it and a corrugated outer sheath (2) arranged outside the insulator (3) in such a way that the piping element (1) is bendable in its entirety. The outer diameter of the insulator (3) is reduced before conducting it to a corrugator (13) inside the outer sheath (2). In the corrugator (13), the insulator (3) reverts towards its larger outer diameter. The free outer diameter of the insulator layer is formed larger than the smallest inner diameter of the outer sheath (2).

  • Publication number: 20090043254
    Abstract: A non-compliant fiber-reinforced medical balloon comprises a first fiber layer and a second fiber layer embedded in a continuous matrix of thermally-weldable polymer material defining a barrel wall, cone walls and neck walls. The fibers of the first fiber layer run substantially parallel to one another and substantially parallel to the longitudinal axis. The fibers of the first fiber layer have a pattern of different lengths and are divisible into a first group and a second group based on length. Each fiber of the first group begins in the neck wall at one end of the balloon, extends continuously in the longitudinal direction and terminates in the neck wall at the opposite end of the balloon. Substantially all of the fibers of the first group have a generally uniform length. Each fiber of the second group begins in the cone wall at one end of the balloon, extends continuously in the longitudinal direction and terminates in the cone wall at the opposite end of the balloon.
