  • Low viscosity liquid crystalline polymer compositions
    Patent number: 6613847
    Abstract: A liquid crystalline polyesters or poly(ester-amides) having improved melt viscosity, is made by reacting the polymer with limited amounts of a compound containing specified functionality, such as hydroxyl, carboxyl, or amine.

  • System and method for preventing bluff erosion
    Patent number: 6612778
    Abstract: A system is provided for preventing erosion of a bluff or hillside having a face extending between a toe at a bottom thereof and a crest at a top surface thereof, and a failure shear plane. The bluff or hillside is subject to excess water accumulation contributing to land mass degradation. The invention is improved by at least one horizontal wick drain positioned behind the failure shear plane in a water saturated zone substantially parallel to the crest of the bluff or hillside for the purpose of controlling drainage of the excess water accumulation. The horizontal wick drain is installed from the top surface of the bluff or hillside so as not to impair the structural integrity and cause land mass degradation of the face thereof.

  • Ballistic resistant article
    Patent number: 6610617
    Abstract: A flexible ballistic resistant article is disclosed that includes a plurality of layers of fabric having an areal density of 2 to 10 kg/m2, wherein at least two of the layers of fabric are loosely woven. The loosely woven fabric layers include fabric woven with a fabric tightness factor of 0.3 to 0.6 and are made using continuous filament yarns with a linear density of at least 200 dtex, a tenacity of at least 10 grams per dtex and a tensile modulus of at least 150 grams per dtex. Adjacent loosely woven fabric layers are joined together by means for securing the layers to restrict the movement of the loosely woven fabric layers relative to one another.

  • Pinch-grip hanger
    Patent number: 6609640
    Abstract: A hanger has a pinch-grip including a pair of vertically-extending components, a biasing spring, and a connector separate and distinct from the biasing spring. The connector pivotably secures together the upper ends of the components for movement, prior to application of the biasing spring to the components, between a substantially unfolded orientation, wherein the components lie in a common plane, and a substantially folded orientation, wherein the components are generally parallel. The connector is integrally molded with the components and configured and dimensioned to lie between the upper ends thereof when the components are in the folded orientation, without substantially inhibiting movement of the upper or lower ends between the closed and open positions.

  • Protective helmet and method of making same
    Patent number: 6609254
    Abstract: A protective helmet includes: a shell, a headband with an absorbent brow pad, and a suspension. A key is secured to each end of each of the straps of the suspension for insertion into respective key sockets spaced about the periphery of the shell of the protective helmet along its lower edge. Of particular importance to the protective helmet of the present invention, many (if not all) of the keys are molded directly to and around a strap, rather than sewn to the strap. In the method of the present invention, lengths of strap material are positioned in a mold, and plastic is injected into the mold cavity to encapsulate the straps and form the plastic component, e.g., a key for the suspension of the protective helmet. A trimming die is used to trim any webbing scrap between parts or other extraneous materials resulting from the molding of the plastic component to the straps.

  • Differential pressure fitting
    Patent number: 6609733
    Abstract: A pipe connection fitting having at one end a tapered edge (1) which communicates at its base with tightening nut (2) which communicates with male pipe threads (3) which communicates with extension member (4) having an angle cut (6) with a flow port (5) through the center of the fitting. Positive differential pressure is created by installing a differential pressure fitting facing into the fluid stream of a flow line. Negative differential pressure is created by installing a differential pressure fitting facing away from the fluid stream of a flow line. Tubing connects the fittings to a pressure tank containing the fluid to be injected in the flow line. Fluid flow past the fittings in the flow line motivates flow from the flow line to the pressure tank and from the pressure tank back to the flow line. The fitting being made of rigid plastic or metal.

  • Panel, particularly a flooring panel
    Publication number: 20030154681
    Abstract: A panel, particularly a floor-covering panel, is provided that has separate horizontal and vertical locking structures. The panel has a first side edge and a second side edge. The first side edge has a groove and a locking lip, and the second side edge has a tongue and a locking tongue. The first side edge of one panel interlocks with the second side edge of another panel without adhesives or fasteners such that the tongue and groove form a joint that provides a vertical interconnection lock and the locking lip and locking tongue form a joint that provides a horizontal interconnection lock. Advantageously, one or more first side edge surfaces opposite surfaces of the second edge locking tongue have a space between them. The separate horizontal and vertical locking structures reduces, if not prevents, damage to the locking structures during joining of panels.
