  • Patent number: 8733075
    Abstract: A process is described wherein pile yarn is woven with cotton weft and warp yarns to produce terry fabrics, such as towels. The fabric is then washed in warm water to dissolve the PVA fibers. The amount of fibers dissolved, depends upon the count of the yarn or yarns used. By dissolving the PVA fibers, a hollow air space is produced throughout the pile yarn, corresponding to an increase in the air space in the pile yarn. By increasing the air space in the pile yarn, the resulting towels are softer and bulkier than standard cotton towels. The present invention further relates to pile yarn in terry woven fabric (warp yarn), or weft yarn, in the case of flat fabrics.

    Abstract: An electrical device such as a headset may have a cable. Wires in the cable may be used to connect speakers in the headset to a connector such as an audio jack. The cable may have a tubular intertwined cable cover that covers the wires. Computer-controlled servo motors in fiber intertwining equipment may be adjusted in real time so that intertwined attributes such as intertwining density and intertwining tension are varied as a function of length along the intertwined cable cover. The fiber intertwining equipment may make these variations to locally increase the strength of the intertwined cable cover and the cable in the vicinity of a bifurcation in the cable and in the vicinity of the portion of the cable that terminates at the audio jack.

  • Patent number: 6490852
    Abstract: An electrically insulated gas chromatograph assembly suitable for high temperature operation in a miniaturized, low power, low thermal mass gas chromatograph instrument is provided. The gas chromatograph (GC) assembly includes a metal capillary GC column (152) having a ceramic fiber insulating layer (156) wrapped about an outer surface thereof. Heater wire (160) is similarly wrapped with a ceramic fiber electrical insulating layer (158). Resistive temperature device (RTD) wire (154) is positioned contiguous an outer surface of insulating layer (156). The composite assembly including insulated capillary GC column (152), insulated heater wire (160), and RTD wire (154), are bound together by applying thereto a spiral wrapped ceramic fiber insulating layer (162).

  • Patent number: 6412261
    Abstract: The subject invention is a method of reinforcing a fiber (10) utilizing Nephila clavipes spider silk (20). The method comprises the steps of suspending the fiber (10) between the first support (12) and the second support (14) wherein the suspended fiber (10) defines a central axis (18) and positioning a silk line dispensing device (16) near the fiber aligned with the central axis (18) for attaching a silk line (20) to the fiber (10). A N. clavipes spider (17) is positioned directly onto the fiber (10), and, once the N. clavipes spider (17) is agitated, it excretes large sticky discs or attachment discs from its pyriform gland to attach its silk line (20) to the fiber (10). The method is characterized by rotating the fiber (10) about the central axis (18) to helically coat the fiber (10) with the silk line (20) for increasing the strength of the fiber (10). The fiber (10) is wound around a spool (30) and directly incorporated into a fabric (40).

  • Publication number: 20020073682
    Abstract: A method of forming an optical fiber cable component including passing an optical fiber ribbon stack (18) through a stack guide (31), the stack guide being rotated and forming a twist in the ribbon stack, and passing the twisted ribbon stack (18′) through a cross-head (40) and extruding a material thereover. In addition, an exemplary cable component production line having a rotatable strander (12) for receiving optical fiber ribbon packages (14) thereon, a rotatable closing die (30) sized to receive the optical fiber ribbon stack, and controller (20) operatively associated with the strander and the closing die for driving the closing die, the controller being operative to effect a predetermined rotational ratio with respect to the strander and the closing die whereby a twist can be formed in the optical fiber ribbon stack.

  • Patent number: 6401442
    Abstract: A machine for dubbing assembly in fly hook production includes a base having a vertical dowel mounted to one end of the base, and a housing mounted to the other end. A work platform is pivotally mounted to one side of the base so that the platform may be elevated or lowered. A drive motor is mounted within the housing. The motor drives a drive shaft. The drive shaft terminates in a hook or eye. A second eye is mounted to the vertical dowel. The second eye projects toward, in opposed facing relation with, the drive shaft. The second eye supports a tensioning spring which has a barrel swivel attached to its opposite end. One or more filaments may be attached to a ring on the barrel swivel so as to extend across the work platform and be secured to the hook or eye on the drive shaft. Dubbing material is applied to a single filament or sandwiched between double strand filaments. Double strand filaments are twisted into a helix to flare the dubbing material.

  • Patent number: 6327843
    Abstract: A cord comprising at least a first pair and a second pair of wires (2a, 2b) of different diameter randomly disposed in transverse cross section thereof, is obtained by arranging in a nacelle (7) of a double-twisting laying machine, a twister (16) operating upstream of a preformer (15). The twister (16), rotating in a direction opposite to that of the impeller (5) and at a speed which is twice that of the impeller, neutralizes the internal torsional stresses induced in the wires (2a, 2b) by effect of the double twisting carried out upon the action of the impeller itself. Thus, a better control of the preforming operation executed on the wires (2a, 2b) disposed parallel in respectively coplanar axes is enabled.

  • Patent number: 6321519
    Abstract: Wire, or other material, is wrapped around a shaft as the shaft turns, producing a coil. After being slid off the end of the shaft, the coil can be re-coiled by repeating the process. By shaping the twice-coiled material, a variety of pleasing jewelry beads may be formed. A variety of jigs useful for performing process are disclosed. One jig is easily and inexpensively manufactured from a unitary length of small rod, bent to provide (a) a wrapping shaft, (b) a feature for securing a free wire end; and (c) an actuator handle. The novel principles can be implemented in many different embodiments.

  • Patent number: RE42265
    Abstract: Cut resistant yarns suitable for knitting gloves and sleeves and methods of making the yarns are disclosed. The yarns are made up of a bundle of continuous filaments formed of a synthetic material, e.g., polyethylene, polypropylene, nylon or polyolefin, and a stretchable yarn, e.g., Spandex® or Lycra®. The yarns are made in such a manner that when completed the continuous filaments are substantially parallel to one another and to the longitudinal axis of the yarn so that items made from them will not twist or curl up, yet will provide good resistance to cutting.
