Abstract: A beveled broom and step-on dustpan cleaning system including a step-on dustpan having a step-on portion configured to allow a user to collect debris in a receptacle of the dustpan when a force is applied on the step-on portion. The dustpan includes a lip portion which is configured to seal against a floor surface upon a user stepping on the step-on portion to collect debris. A beveled broom having a broom head configured with a beveled or chamfered shape at a functional angle to provide an effective and efficient contact surface to a floor surface to collect debris during use.

Abstract: A bearing bush includes at least one sealing element and one bearing element. The sealing element is provided with at least one sealing lip. The bearing element is substantially tubular. The bearing element includes a plurality of protrusions extending in the axial direction on the outer circumference. The inner diameter of the bearing element is larger in the sections corresponding to the protrusions than in the remaining sections.

Abstract: A filter for cleaning air includes: a housing; layers of a filter medium, the layers being arranged in the housing; and separator plates. One separator plate is arranged between each two layers of the filter medium. The separator plates are provided with a perforation. In an embodiment, the separator plates are fluted, corrugated, or folded.

Abstract: Sealing element for producing an electrically conductive connection between a first machine element and a second machine element, including at least one sealing disc and a support ring, the support ring comprising an axial flange and a radial flange, the sealing disc being formed from an electrically conductive non-woven fabric, and the sealing disc being secured at least in sections along the axial flange by means of a clamping connection between the support ring and the second machine element.

Abstract: A filter element includes: a frame having a peripheral elastomer body in which a reinforcement element is embedded; and a filter pocket. The frame is connected to an opening in the filter pocket with a connection established integrally by the elastomer body. In an embodiment, the elastomer body is molded on the filter pocket.

Abstract: A flat mop cover for mop-cover holder, where the flat mop cover comprises an elongate basic body. The basic body has a first elongate surface and a second elongate surface, which lie opposite one another. At least one foam-material layer is disposed between the elongate surfaces, and the two elongate surfaces are each configured to be cleaning surfaces. The two elongate surfaces are disposed such that a plate-shaped carrying element of a mop-cover holder is configured to be disposed in a sandwich-like manner between the two surfaces. The basic body is configured to absorb in a reversible manner at least four times, and at most twenty times, its dry weight in liquid, and wherein the foam-material layer has no fibers.

Abstract: A seal includes: a seal ring, having at least one dynamically stressed seal lip; a supporting ring made of a toughened material; and a connecting device made of an elastomeric material. The seal ring and the supporting ring are connected to one another. The supporting ring includes a radial leg, to which, in a radial direction, the seal lip is fixed. The radial leg is formed of two parts and, in the radial direction, has arranged a first partial leg and, in an other radial direction has arranged a second partial leg. The partial legs are associated adjacent with a first radial distance and delineate a first gap. The first partial leg is connected with the seal lip. The first and the second partial legs are fixed to one another by the connecting device. The connecting device, when viewed in cross section, has an axial length and a radial height.

Abstract: A seal includes: a sealing ring made of a sealing material; and at least one shielding ring made a soft magnetic material for shielding against electromagnetic interfering waves. In an embodiment, the at least one shielding ring is formed by a ferrite ring. In an embodiment, the at least one shielding ring includes at least two shielding rings, the at least two shielding rings being arranged in a functional series connection.

Abstract: A ventilation system for a mobile structure, in particular a motor vehicle, includes: a variably adjustable filter device including at least one controllable, variable filter characteristic with regard to a pollutant class; means for collecting information about the air quality in the surroundings of the mobile structure and in particular information about the air quality in an interior of the mobile structure; and a control unit for varying filter characteristics of the filter device in a variable, in particular continuous, manner, on the basis of the information about the air quality.
