Abstract: The invention relates to known housing seals of two housing parts lying against each other, a first housing part (1) having a first sealing surface (6) and a second housing part (2) having a second sealing surface (7), which housing seals are equipped with a seal (15), which is inserted into a groove (10) in the first sealing surface (6) of the first housing part (1), wherein the groove (10) is covered by the second sealing surface (7) of the second housing part (2). According to the invention, in order to prevent crevice corrosion, the groove (10) has an opening (11) between the sealing surfaces (6, 7), which is used to ventilate the groove (10) having the inserted seal. The invention is intended for water pumps, in particular for auxiliary water pumps of motor vehicles.

Abstract: A cutting and transport roller for material webs includes media outlet openings in its peripheral surface to which varying pressure can be applied to control the seating pattern of the material web on the peripheral surface of the roller. The roller has a system of pressure feed lines by which the media outlet openings are connected to means for supplying the media. The roller has at least one pressure reservoir that is a part of the pressure feed line system and that can be connected by a valve to at least one part of the media outlet openings.

Abstract: An electromechanical switching device is disclosed for protecting electrical wires and/or consumers. In at least one embodiment, the device includes at least one thermal triggering element and at least one switching device-internal heat source. For the at least one thermal triggering element, the electromechanical switching device includes a thermal coupling of at least one of the switching device-internal heat sources. At least one embodiment of the invention also relates to the use of a thermal coupling.

Abstract: Device for continuous winding of webs onto winding shafts or winding cores to winding rollers, with a pressure roller supported in a frame that can be engaged on the winding shaft or winding core. This engagement is effected with limited friction and in a sensitive manner by means of a drive, with the pressure roller being supported on at least one steering rod that is pivot-connected to two guides, the other ends of which are pivot-supported in the frame.

Abstract: Cutting and transport roller (1) for material webs, that comprises of media outlet openings (14) in its peripheral surface (7) to which varying pressure can be applied to control the seating pattern of the material web on the peripheral surface (7) of the roller (1) and that comprises of a system of pressure feed lines (3, 4, 5, 11, 12, 13) by means of which the media outlet openings (14) are connected to means for supplying the media. The present invention differs from the prior art by at least one pressure reservoir (3, 4) that (3, 4) is a part of the pressure feed line system (3, 4, 5, 11, 12, 13) and that can be connected by a valve to at least one part of the media outlet openings. In the present invention, a process is introduced and claimed for controlling the seating pattern of a material web on the peripheral surface of a cutting- and transport roller (1). Said process can be implemented using the roller (1) in accordance with the invention.

Abstract: Device for continuous winding of webs onto winding shafts or winding cores to winding rollers, consisting of arms supporting the winding shaft that, or a pressure roller that can be engaged on the winding shaft or winding core, or the forming winding roller, respectively, which is supported in a frame and with a knife separating the web during a roller change. In order to be able to engage the pressure roller with the winding core or winding roller in a low in friction and sensitive manner by means of a drive, the pressure roller is supported on at least one steering rod, which is pivot-connected to two guides, the other ends of which are pivot-supported in the frame.

Abstract: The invention relates to a tension-relief component for electrical leads (14)—particularly of an electric motor—provided with an insulation, having a capacitor (12) for suppression of electromagnetic interference, wherein a contact element (48) is provided that is in electrical contact with the capacitor (12), wherein a contacting of at least one lead (14) takes place in that the contact element (48) penetrates the insulation of the lead (14). The contacting of the lead (14) takes place preferably by means of a mandrel (48). The tension-relief component (10) comprises a retaining clip (26), by means of which the capacitor (12) is secured in the tension-relief component (10), while the mandrel (48) is inserted in the tension-relief component (10).

Abstract: A brush holder for mechanically commutated electric motors has a support plate, a shaft-like guiding container mounted on the support plate for guiding a sliding brush pressed by a spring force against the commutator of an electric motor. The guiding container has side walls extending transverse to the support plate and provided with legs. A pressing spring is formed as a strip-shaped flat spring and has end portions which are oppositely rolled to form rollers abutting against the legs of the guiding container on surfaces of the legs which face the commutator and also have a central portion arranged to load an end surface of the sliding brush facing away from the commutator.

Abstract: In apparatus for laying for flexible sheets into a folded Z-shaped form, a supply conveyor (1) is disposed above means (9) for supporting or transporting the leading end of each sheet (26). Clamping means (16, 17) for laterally clamping the sheet on a transverse line are provided laterally of the supporting or transporting means (9). A reciprocatable transverse rod (22) is provided in a gap between the supply conveyor (1) and the means (9). Further conveyor means at right-angles to the supporting or transporting means (9) define an inlet which consists of double belt conveyors (30) or pairs of rollers, is extensible and closable in a plier-like manner, and is arranged so that one side edge of each sheet (26) folded to Z-shape by the transverse rod (22) lies within said inlet.

Abstract: An apparatus for opening and folding the end of a flattened tubular sheet to define the rectangular base of a bag or sack to be made from the sheet comprises a table having a slot through which the flattened sheet projects, the projection being formed into a bag base by suckers locating the projection in a pre-opened condition and grippers which engage opposed margins of the projection, one of the grippers being fixed and the other being secured to a pivotable arm.

Abstract: The leading end of an intermittently fed flattened tubular web is clamped by a gripper, whereupon a severing mechanism cuts a section from the web. The gripper advances the leading end of the tube section before the trailing end has cleared a pair of clamping rollers and while a folding roller engages an intermediate portion of the section and moves it laterally to form a loop in the tube section before the latter is discharged transversely.

Abstract: A web of material is intermittently fed by feed rollers between and beyond pairs of clamping jaws comprising separated segments defining a gap receiving a reciprocatable severing knife. Beyond the clamping jaws, suction means hold the leading web end and, after said end has been severed, can be swung onto a support for a workpiece to which the severed web section is to be applied.
