  • Publication number: 20050045297
    Abstract: A method of producing a slurry of material effective for application to designated regions on cigarette paper to affect the burn rate in the designated regions, includes the steps of cooking a fibrous cellulosic material, bleaching the material, pressing the cooked and bleached material to remove liquid, drying the pressed material, milling the dried material to produce fibers of a desired size and mixing the milled material with water. Flax straw can be used as one source of the fibrous cellulosic material, and can be subjected to a hammering process for removal of non-fibrous components of the flax straw and for reduction in the fiber size before the cooking of the fibrous cellulosic material.

  • Publication number: 20040190686
    Abstract: Whether or not protection circuitry for a span-powered remote digital subscriber loop unit is properly connected to earth ground is determined by the deliberate assertion and detection of a ground fault from a central office line card location. The span-powered remote unit is augmented to place a controllable conduction path in circuit with the span-powered loop and an earth ground pin. If the earth ground pin has been properly connected to earth ground, applying the conductive path will place a ground fault on the span, which is detected by a ground fault detector within the central office line card. If the ground fault detector does not detect a ground fault in response to the application of the conductive path, the line card forwards a negative ground fault event message to a test center, so that a service technician may be dispatched to the remote unit to correct the problem.

  • Patent number: 6229025
    Abstract: The present invention relates to a process for alkylating hindered sulfonamides by Michael addition to propiolates, and to novel intermediates prepared in said process. The products of these reactions can be converted into pharmaceutical compounds useful in the treatment of disease states mediated by matrix metalloproteinase enzymes. Novel intermediates prepared according to the present invention include compounds of the formula wherein R1 is (C1-C6)alkyl or optionally substituted benzyl; R2 and R3 are independently (C1-C6)alkyl or R2 and R3 are taken together to form a three to seven membered cycloalkyl, pyran-4-yl ring or a bicyclo ring of the formula wherein the asterisk indicates the carbon atom common to R2 and R3; and group Q is as herein described.

  • Patent number: 6119906
    Abstract: The plastic hanger is provided with a cross-bar of S-shape cross-section and a pair of clips. One jaw of each clip is integrally molded with the cross-bar while the opposed jaw is separately molded and held in place by a spring clip which biases the clamping ends of the jaws together. The cross-bar is provided with spacers at the ends to space adjacent hangers apart. The upper finger-receiving end of the jaw integrated with the cross-bar is contoured and provided with a shoulder to give the appearance that the upper end of the jaw is separate from the cross-bar.

  • Patent number: 6068250
    Abstract: A circular multi-wave composite compression spring (10) is formed from a carbon fiber (58) reinforced laminate. The circular compression spring (10) is comprised of unidirectional graphite fibers (58) encased in a polymeric resin of generally rectangular cross-section such that adjacent crests (14) and troughs (16) of the waves in adjacent turns (12) of the spring (10) contact each other along a radial line generally extending from the longitudinal axis (30) of the spring (10). The line contact provides for increased fatigue life and more stable loading of the spring (10) under compression. The carbon fiber reinforced laminate provides comparable strength characteristics similarly configured springs fabricated from conventional materials while providing significantly reduced weight. Furthermore, the composite spring (10) offers increased performance parameters such as increased linearity response over a wider spring deflection range and with insignificant hysteresis.

  • Patent number: 6006985
    Abstract: An envelope has a tear panel created by lines of perforations that begin on either side of a pull tab formed in one or more of the panels of the envelope and divergingly extend away from the pull-tab. The pull-tab is conveniently grasped to exert a force that will detach the tear panel along the lines of perforations in order to readily inspect and extract the contents of the envelope.

  • Patent number: 5664881
    Abstract: A drum mixer is provided with a rotatable cylinder in which aggregates, reclaimed asphalt pavement and liquid asphalt are mixed to produce an asphaltic composition. The drum cylinder includes a first region, in which virgin aggregate is heated and dried by heat radiation and the stream of hot gases produced by a burner flame flowing in countercurrent flow to the aggregate itself to establish a highly beneficial heat transfer relationship. A second region doubles as combustion and mixing zones. In the mixing zone the reclaimed asphalt pavement and liquid asphalt is added and mixed with the aggregates. The combustion zone is formed along the center of the mixing zone by an elongated combustion assembly disposed along the central axis thereof. The combustion assembly and chamber extend from the discharge end of the drum through the mixing zone to the heating and drying zone to segregate the hot gases from the asphalt, thereby preventing degradation of the final product.
