  • Patent number: 5849379
    Abstract: A split sleeve for insulation of heat generating components, such as an exhaust gas recirculation device, comprises an outer layer of knitted woven or braided glass fiber yarn. A first metal wire skeleton or frame in the form of a continuous wire support for the outer layer is bent in a first step with a series of reverse bends to form a comb-like structure and in a second step to a C-shaped cross-sectional configuration in which the wire defines a cavity and the wire bends define an opening extending lengthwise of the cavity. A layer of heat insulating mineral paper is spaced from the cover layer by the metal wire skeleton. The heat insulating mineral paper is provided with a metal foil layer on the side away from the metal wire skeleton. A second metal wire layer configured like the first extends lengthwise of the sleeve and spaces the reflective surface of the foil from the heat generating component.

  • Patent number: 5846641
    Abstract: The present invention discloses a mixed ionic electronic conductor membrane comprising a dense layer sandwiched between two porous layers. Furthermore the invention discloses the application of this membrane to the use of partial oxidation of hydrocarbons. One porous layer, which is in contact with air, promotes the generation of oxygen ions. The oxygen ions diffuse through the dense layer to the second porous layer which is in contact with a hydrocarbon and result in partial oxidation of the hydrocarbon.

  • Patent number: 5846640
    Abstract: The invention relates to a method for the preparation of the fibre product pre-impregnated with a polymer (prepreg) where the method includes: a) coating the fibres with a powder comprising at least one polymer and optionally an agent having the ability to initiate the polymerization reaction of the polymer, b) adding to the composition obtained in step a) a solvent possessing the ability to dissolve the polymer but lacking the ability to initiate the polymerization reaction of the polymer, and c) evaporating the solvent. Alternatively, the polymer (optionally including the initiating agent) can first be dissolved in the solvent after which the fibres are contacted with the solution thus obtained and the solvent is evaporated. The surface of the fibres is preferably treated so as to facilitate the bonding of the polymer to the fibres, whereafter the surface treated fibres are coated with the polymer powder.

  • Patent number: 5846890
    Abstract: A temporary surface covering to allow or facilitate the circulation of vehicles on sandy or swampy soils. The surface covering is formed of a woven structure formed from weft threads (N.sup.o 1 to 26) of the monofilament type disposed along a single layer and warp threads (N.sup.o 1 to 10), also disposed along a single layer. The weave of the woven structure is such that each warp thread is interlaced with the weft thread preferably and approximately along half the intersections of the rows and columns of the weave so as to obtain, for each warp thread, at least one tight single weave zone (A) followed by a loose thread zone (B). The alternation of the various zones provokes retightenings of the weft threads creating a large relief (S1, S2, C1, C2) of the fabric embodied.

  • Patent number: 5843568
    Abstract: A fiber-reinforced article includes an expanded core layer having opposing first and second surfaces with a thickness defined therebetween. The expanded core layer is formed from a composition comprising a thermoplastic material and fibers with average length of not less than about 1 mm, with at least a portion of the fibers being coated with the thermoplastic material. The fibers collectively define a network structure in which the fibers are interconnected with each other and fixed relative to each other via the thermoplastic material so that the coated fibers define interstitial voids therebetween. The article further includes first and second skin layers, the first skin layer having a surface integrally connected to the first surface of the expanded core layer and the second skin layer having a surface integrally connected to the second surface of the expanded core layer.

  • Patent number: 5843559
    Abstract: An insulating fiber mat is comprised of a plurality of fibers bound together by a binder means and distributed throughout the mat. At least some of the fibers throughout the mat are inclined. The inclined fibers on opposed sides of a central horizontal plane of the mat have opposed angles of inclination. This permits the fiber mat to be easily separated substantially along the central horizontal plane by applying a pulling force on one side of the mat in the direction of the inclined fibers.

  • Patent number: 5840378
    Abstract: An endless woven fabric for condensing paper material and a method for forming such an endless fabric which removes ink and other extraneous substances from the aqueous solution of reclaimed paper material. On the endless fabric formed by weaving plastic monofilaments, an antiflexing part, 30-50 mm in width, is provided on at least one end of the selvage in the direction of width by causing thermoplastic resin to fill not less than 85% of an empty space in the endless woven fabric. Further, a guide ridge of thermoplastic resin is formed by causing thermoplastic resin to fill an empty space in the end parts on the running surface of the endless fabric, and is welded with the antiflexing part integrally. Platelike reinforcing strips are formed in a length nearly equal to the width of the endless fabric. The strips are extended between the opposite ends of the endless fabric by causing thermoplastic resin of the strips to fill not less than 85% of an empty space in the endless fabric.

  • Patent number: 5840234
    Abstract: A three-dimensional plexifilamentary fiber (26) of a high-density polyethylene group obtained by supplying a polymer to a dissolving area in a state such that the polymer is melted by a heated screw extruder (compressing zone 13, metering zone 14 to 16), supplying a solvent (CCl.sub.3 F) into the melted polymer (feed opening 18), mixing and dissolving the polymer and the solvent to make a polymer solution, and extruding the polymer solution from a nozzle (24 in FIG. 24) arranged in the dissolving area into a low pressure area. A nonwoven fabric is obtained through a process in which the fiber (26) is spread by striking the fiber against a skirt portion (33) having a fiber swinging face (34) and a cushioning face (35), and this nonwoven fabric has an excellent strength, covering property, and whiteness.

  • Patent number: 5840414
    Abstract: Solid polymer membrane fuel cell product water which forms on the oxidant side of the membrane is removed from the active area of the cells in a fuel cell power plant by being absorbed into and wicked away from the active area by a porous carbon body which contacts the membrane. The carbon body may be an oxidant reactant flow field plate. The pores in the carbon body are partially filled with metal oxide granules which impart increased wettability and water absorption capacity to the carbon body.
