  • Tire Chain Tightening Apparatus and Method
    Publication number: 20110088824
    Abstract: A tire chain tightener for use on automotive, truck, or other vehicle traction chains and similar devices. The tire chain tightener has an length of elastic material with a hook attached to each end. Intermediate hooks are spaced along the elastic material between the two ends. One of the ends may be uniquely marked with instructions for correct installation of the tire chain tightener. When correctly installed, a tire chain tightener with N+1 hooks will form a symmetrical N pointed star inscribed in the circumference of the tire chains. The star is further centered about the tire. The tire chain tightener exerts a centering force on the tire chains. Since only one hook at a time is installed, the effort to install the tire chain tightener is reduced, enabling people of limited strength to install them.

  • Process for the production of polyarenazole yarn
    Patent number: 7776246
    Abstract: The present invention concerns a process for making a polyareneazole multifilament yarn comprising: a) extruding a solution comprising polyareneazole polymer and polyphosphoric acid through a plurality of orifices to produce filaments; b) forming a multifilament yarn from said filaments; c) hydrolyzing at least some of the polyphosphoric acid in the yarn by heating the yarn to a temperature above about 120° C. for up to about two minutes; d) washing at least some of the hydrolyzed polyphosphoric acid from the yarn; e) drying the washed yarn; f) optionally, heating the yarn above about 300° C., and g) collecting the yarn at a speed of at least about 50 meters per minute.
