  • Patent number: 6751938
    Abstract: The independent torsioning unit consists of two different units: the case frame and the programming and control unit. The case frame houses the spindle axis, the electrical motor, the drive belt, the yarn guide, the vertical deflection roller, the horizontal deflection pulley and the impulse reader. The programming and control unit consists of a processor, the programming keyboard and a frequency converter that supplies and controls the motor. The independent torsioning unit is used as an auxiliary feeding machine that enhances the performance of any type of main processing machine.

  • Patent number: 6601377
    Abstract: The present invention relates to gland packing materials made from expansive graphite, gland packing made from expansive graphite made from the materials, and a producing method of gland packing made from expansive graphite; braiding thread is a filamentose with winding or twisting a strip laminated sheet that a bundle of sprit fiber is laminated and unified through an adhesive layer so as to be a reinforcing material, and a cord body is constructed by braiding the braiding thread, then a packing is constructed by pressure forming this cord body.

  • Patent number: 6581366
    Abstract: A cut-resistant stretch yarn having a first elastic core yarn with a first wrapper yarn spirally-wrapped around the elastic core yarn in a first twist direction. The first wrapper yarn is a highly cut-resistant yarn. A second wrapper yarn is spirally-wrapped around the elastic core yarn and the first wrapper yarn in a second twist direction. The second wrapper yarn is a highly cut-resistant yarn. The elastic core yarn may be an elastomeric yarn, neoprene or rubber.

  • Patent number: 6574949
    Abstract: The present invention is related to a pneumatic control ring (1) with application in ring twisting machines, continuous spinning frames, and double twisting frames, made of sintered, porous material and with a chamber (4) in which an air-lubricant mixture is pressure injected, which creates an air cushion between the ring (1) and the thread and produces constant and homogeneous lubrication in the contact area between them, in order to avoid the balloon effect and to prevent the thread from wearing down by friction against a surface which is the balloon control ring, facilitating high speed thread processing.

  • 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: 6408607
    Abstract: A method for false twist texturing a synthetic yarn, as well as the thus-produced crimped yarn, wherein a false twist is produced on the yarn at a speed of a false twist unit, which exceeds 2.2 times of the yarn speed and is above a saturation limit for absorbing a false twist in the yarn. The overtwisted yarn is set in the false twist zone at a temperature higher than 200° C. In proportion with the advancing speed, the withdrawal speed does not exceed 1.4 times the advancing speed, and is below 1,000 m/min. With that, a false twist textured crimped yarn is produced, which has large and small cross sections with curls and bows, which alternate with one another and have opposite directions of twist.
