Abstract: A cleaning device includes a base body, a rotatable brush roller disposed on the base body, a dirt container disposed on the base body, a cloth holder attached removably to the base body, and a cleaning cloth attachable to the cloth holder.

Abstract: A filter arrangement for cleaning fuel cell supply air, including at least two filter layers, whereby a first filter layer is designed as a coarse filter and a second filter layer as a fine filter, wherein the second filter layer includes an electret filter material.

Abstract: A torsionally flexible coupling having a rotational axis (1), including a first ring (2) and a second ring (3, 4), which enclose each other [one enclosing the other] at a radial distance, at least one ring-shaped first spring element (5) made of elastomeric material being positioned in the annular clearance (13) formed by the radial distance; and a belt pulley (7) being fastened, relatively having torsional flexibility, to at least one of the rings (2; 3, 4) with the aid of a second spring element (6) made of an elastomeric material, and being supported on at least one of the rings (2; 3, 4) at least in the radial direction with the aid of a sliding bearing (8, 9); the sliding bearing (8, 9) being formed by a rubber layer (9) having at least two embedded sliding rings (8).

Abstract: A hydraulically damped bearing having a first anchoring member (2) and a second anchoring member (3) that are arranged in a movable fashion to one another, having a spring element (6) operating between the first and second anchoring members (2, 3), and having an operating chamber (10) filled with a damping fluid and a compensation chamber (11) separate from the operating chamber (10) and connected to it via a channel (14) that is defined by the channel walls and that allows the fluid to pass through. The volume of the operating chamber (10) changes due to the relative movement of the first and second anchoring members (2, 3), such that the damping fluid is moved in the channel (14) between the compensation chamber (11) and the operating chamber (10). The operating chamber (10) and the compensation chamber (11) are separated by a separating wall (12) that is impacted on both sides by the damping fluid.

Abstract: Disclosed is a handle for household utensils, in particular for floor cleaning utensils, the external polygonal contour of which presents side faces (6) and edges (7).

Abstract: A method for surface treatment of a fibrous polyphenylene sulfide or polysulfone is based on the use of a gas mixture of 1 to 5% in volume of elemental fluorine, of nitrogen as carrier gas and of no more than 20% in volume elemental oxygen. The gas mixture affects the fibers until the total fluorine content in the fiber material is between 0.01 and 0.2 percent in weight. The fibers treated in this manner are particularly suited as separator material in electrochemical energy storage devices with an alkaline electrolyte.

Abstract: A homogeneous floor covering composed of elastomer, varicolored granular particles contains 3 to 20 per cent by weight of a copolymer of ethylene, including at least one comonomer of vinyl esters of saturated carboxylic acids having up to 4 C-atoms in the acid group, or including at least one unsaturated mono- or dicarboxylic acid, or including at least one ester of unsaturated mono- or dicarboxylic acids having up to 8 C-atoms in the alcohol portion. In this context, the ethylene content of the copolymer is 40 to 95% per cent by weight, the rest is comonomer, and the melt-flow index of the copolymer must lie between 0.1 and 50. A corresponding manufacturing process is specified.

Abstract: Guide-ring arrangement on a cylindrical guide part for the relative guiding of an elongate guided part having a guide ring where the rear surface projects in a convex manner.

Abstract: A vibration dampener adapts to different speeds of rotation. The device comprises a drive collar (1) and several inertial masses (2). The collar rotates around a central axis (3) and the inertial masses pivot around peripheral axes along the direction of rotation. Each inertial mass is secured to the collar by two bolts (5). The bolts, which extend parallel the central axis, are distributed around the circumference of the collar, and roll back and forth along arcs (6). The arcs are concave toward the central axis in the vicinity of the collar and concave in the opposite direction in the vicinity of the inertial masses. The bolts extend through a guide (7) toward the sides facing away from the associated arcs.

Abstract: A lipped sealing ring for a mechanical component that moves relatively to it. The lip is of a polymeric material, is flexible, and is forced subject to resilient compression against the component in the vicinity of a sealing gap. A helical shoulder extends longitudinally and at an acute angle to the axis of the component through at least one point along the circumference of the gap. The sealing gap is packed with wax at least in the vicinity of the helical shoulder.

Abstract: A device for crimping a plastically deforming metal pole shoe (1) around the end (2) of a cable that has been inserted into it. The device comprises an anvil (3), a die (4), a sensor (5), and a comparator (6). The shoe is placed on the anvil and the die is advanced toward it, deforming the shoe. The sensor emits a signal once the shoe has been deformed to the maximum, and the comparator compares the signal with a reference and emits either an "accept" signal or a "reject" signal. The "reject" signal emitted by the comparator actuates a cable-end trimmer that cuts part-way or all the way through the cable. Consequently, the device will always either acceptably crimp pole shoes to the ends of cables or reliably indicate defective connections.

Abstract: A pocket filter includes a front frame which accommodates at least two filter bags. The top of each bag accommodates a reinforcing frame. The bags are secured dust-tight to one another, to the reinforcing frames, and to the front frame. The front frame is a severed at at least one point along its perimeter. The front frame has a U-shaped channel around it that opens inward, and the reinforcing frames can be inserted into the channel when the front frame is open at the severed point. The reinforcing frames match each other and match the size of the front frame, creating a dust-tight contact between all the adjacent reinforcing frames and the inner surface of the channel when the front frame is closed at the severed point. Facing webs, disposed in the channel opening on each side of the "U", create a dust-tight contact with the reinforcing frame.
