Abstract: A grounding ring, including a substantially circular-ring-shaped hub and at least two sliding contacts, which are arranged on the outside of the hub in the radial direction, extend in the circumferential direction and, in the manufactured state of the grounding ring, are arranged adjacent to one another at a distance from one another in the circumferential direction and delimit a circumferential gap with their sides facing one another in the circumferential direction, and wherein the circumferential gap is substantially bridged during the intended use of the grounding ring by the mutually facing and mutually non-overlapping sides.

Abstract: An arrangement for producing an electrically conductive connection between a first machine element and a second machine element, comprising an electrically conductive disk which is secured to a supporting body, wherein the disk is provided with a bore for receiving a second machine element, wherein slots are introduced into the disk starting from the peripheral edge of the bore.

Abstract: An electrically conductive nonwoven includes: a raw nonwoven having a first electrical conductivity; and electrically conductive particles having a second electrical conductivity. The second electrical conductivity is higher than the first electrical conductivity. In an embodiment, the particles have a proportion by weight of from 30% to 60%. In an embodiment, the particles have a size of from 3 ?m to 8 ?m.

Abstract: A slide ring seal has a slide ring, supported such that the slide ring is axially movable, and a counter ring. The slide ring and the counter ring have respective sealing surfaces contacting one another. The slide ring sealing surface faces the counter ring sealing surface. The slide ring is pressed against the counter ring by a bellows-like spring element. The slide ring seal may be designed so the slide ring seal has an especially flexible slide ring and/or counter ring after economical and trouble-free production, the slide ring seal has at least one sealing surface with elevations or unevenness of a magnitude from 0.1 ?m to W mm, W conforms to the formula W=0.03 Dm/s, wherein the average diameter Dm is the average of the circular-ring-shaped sealing surface's outside (Da) and inside (Di) diameter, and s is the slide ring or counter ring thickness.

Abstract: A slide ring seal has a slide ring, mounted in an axially movable manner, and a counterpart ring, wherein the slide ring and the counterpart ring each have sealing surfaces which bear against one another, wherein the sealing surface of the slide ring is situated opposite the sealing surface of the counterpart ring, and wherein the slide ring is pressed against the counterpart ring by a spring, wherein, with regard to refining and developing a slide ring seal of this type such that, while being inexpensive and easy to manufacture and having a construction involving a particularly small number of components, it seals off two chambers in a reliable and permanent manner, and the counterpart ring is formed in one piece with an axial projection which can be assigned to a shaft in order to fix the counterpart ring on the shaft.

Abstract: A mechanical face seal including a primary ring which is axially movably mounted, and a mating ring (3, 3?, 3?), wherein the primary ring and a mating ring each comprise adjoining sealing surfaces. The primary ring is pressed by a spring against the mating ring. The spring has a bellows-like shape. The spring is made out of an elastomer. The mechanical face seal achieves a small installation space for a mechanical face seal.
