  • Publication number: 20050011735
    Abstract: The invention relates to an endless, belt-shaped tension element (1) for a conveyor system with at least one joining point (2) comprising an elastomer, in particular a cross-linked and/or thermoplastic elastomer, at least one reinforcing layer and optionally at least one tension support (3), two ends of the at least one reinforcing layer being disposed at the at least one joining point (2). An insert piece (6) is disposed between the two ends at the joining point (2), subtending an angle ? with the tension element longitudinal extension, and the ends of the at least one reinforcing layer overlap with the insert piece (6).

  • Publication number: 20050002995
    Abstract: The invention relates to a multi-layered prophylactic article (1) made from an elastomeric base layer (5) with an internal and an external surface (6, 7), at least a part region of the internal surface (7) having an anti-friction layer (4) made from a polymeric material with an internal surface (9). At least one active substance and/or dye inside particles (11) is disposed on the internal surface (9) of the base layer (5) and/or between the base layer (5) and the anti-friction layer (4) and/or in the anti-friction layer (4) and/or on the internal surface (9) of the anti-friction layer (4), and/or a layer incorporating the at least one active substance and/or dye is disposed in at least a part-region between the base layer (5) and the anti-friction layer (4), which anti-friction layer (4) has regularly recurring raised areas or recesses of an irregular shape, produced by rapidly removing liquid from the anti-friction layer (4).

  • Patent number: 6673431
    Abstract: The invention relates to a hand-rail that can be used for escalators, moving pavements. The inventive hand-rail has a C-shaped cross-section, outer layers in the form of a sliding layer and a rubber top layer for the user, a layer with tractive support elements, especially steel chords that are embedded in rubber and oriented in a longitudinal direction, and at least one respective reinforcing layer extending into the lip areas on both sides of the tractive support elements. At least one of the reinforcing layers consists of a rubber layer with homogeneously distributed short fibers with a preferred orientation, extending at an angle deviating from 0° in relation to the longitudinal direction of the hand-rail.

  • Patent number: 6440498
    Abstract: The invention relates to an article, in particular a glove, a condom, or the like, which is comprised of a flexible rubber and/or plastic, is embodied having at least one section of the surface intended contact or rest against human skin, which article is provided with a slip coating in a section of the surface. This slip coating is comprised of a polymeric material and at least in sections, has repeating shape deviations of the surface that are recessed in relation to a raised, net-like structure. The ratio of the average spacings between the shape deviations to their depth in relation to the raised, net-like structure is between 500:1 and 5:1 and the average roughness depth is between 0.5 and 100 &mgr;m, preferably between 1 and 40 &mgr;m.
