  • Patent number: 5955172
    Abstract: A shoe with an outer layer and a ventilation layer positioned against the inside of the outer layer. The ventilation layer has a flat textile structure, at least on its side which is turned towards the inside of the shoe, which is held at a distance from the outer layer by spacers. The flat textile structure turned towards the inside of the shoe contains between 30 and 100 weight percent multifilament flat yarns made of synthetic polymers and between 0 and 70 weight percent other yarns. In particular, these flat yarns have a filament titre of at least 3 dtex.

  • Patent number: 5955386
    Abstract: An open weave, air permeable fiber pad is formed from a plurality of compressed, interlocked fiber strands. A non-uniform, three dimensional grid of spaced apart, expandable graphite particles are secured at randomly spaced apart intervals to individual fiber strands with a particle distribution density sufficient to form a barrier to air flow through a defined area of the fiber pad when exposed to a source of heat causing the expandable graphite particles to be converted from their normal volume to a heat-activated, substantially expanded volume.

  • Patent number: 5952067
    Abstract: A biaxial braided sleeve braided together in a diamond braid style. The braided sleeve has an outer layer or set of thick, uncrimped strands extending in one helical direction and an inner layer or set of thick, uncrimped strands extending in the other helical direction. Much thinner containment strands hold the thick strands in position. A braided sleeve is thus provided which can have one material on the outside and a different material on the inside. For example, the inside material can be fluorocarbon polymer and the outside material can be fiberglass, providing a bearing liner. The two counter-rotating sets or layers of thick uncrimped strands provide enhanced mechanical properties.

  • Patent number: 5939337
    Abstract: A toner fixation film has an exothermic layer within which an eddy current is induced with application of a magnetic field and then heat is generated. The exothermic layer is a composite layer in which an exothermic part and resin part coexist. The toner fixation film can offer a sufficient heat generation necessary for toner fixation, and has enough flexiblity to permit curvature separation. A toner fixation apparatus comprises the toner fixation film and at least one coil for producing an alternating magnetic field for eddy current induction.

  • Patent number: 5939176
    Abstract: An on-machine-seamable multi-axial press fabric for the press section of a paper machine is made from a base fabric layer assembled by spirally winding a fabric strip in a plurality of contiguous turns, each of which abuts against and is attached to those adjacent thereto. The resulting endless base fabric layer is flattened to produce first and second fabric plies joined to one another at folds at their widthwise edges. Crosswise yarns are removed from each turn of the fabric strip at the folds at the widthwise edges to produce seaming loops. The first and second fabric plies are laminated to one another by needling staple fiber batt material therethrough. The press fabric is joined into endless form during installation on a paper machine by directing a pintle through the passage formed by the interdigitation of the seaming loops at the two widthwise edges.
