Abstract: The invention relates to a fastening element, in particular an eccentric screw, and an adjustment system comprising a fastening element. Fastening elements are already known from the prior art. These are often used in an adjustment system in order, for example, to adjust chassis parts of a vehicle. For this, eccentric elements are often mounted or moulded on the fastening element in order to achieve adjustability in this way. To achieve secure positioning of the eccentric element on the fastening element, it is often guided on the fastening element in a rotationally fixed manner via a groove. The problem with this, however, is that the groove results in particularly expensive production of the fastening element, in particular owing to the shaping of the thread of the fastening element, since the shaping tool for shaping the thread is often damaged and/or severely worn by the groove, in particular the ramp thereof, and therefore these tools have only a short service life.

Abstract: High-strength screw (1), with a head (2) with a tool engagement contour (4), a shank (3) with a free end (5) pointing away from the head (2), a threaded section (6) with a thread (7) being arranged on the shank (3), the thread (7) being formed as a metric ISO thread or inch thread, the head (2) and the shank (3) being designed as materially separate parts, the head (2) having a coupling recess (8) arranged radially inside with an axial force transmission element (9) and a torque transmission element (10), the shank (3) having a coupling element (11) arranged radially outside on its outer circumference with an axial force transmission counter element (12) and a torque transmission counter element (13), the coupling element (11) engaging in the coupling recess (8), the axial force transmission element (9) and the axial force transmission counter element (12) being designed and arranged to positively interlock in such a way that an axial translatory movement of the head (2) relative to the shank (3) in the direc

Abstract: A high-strength screw (1) includes a head (2) having a tool engagement external contour (7) and a tool engagement internal contour (8). For example, the tool engagement external contour (7) is an external hexagonal and the tool engagement internal contour (8) is an internal hexagonal. A plurality of additional pocket-shaped impressions (13) are arranged in the tool engagement internal contour (8) between corners (12).

Abstract: A mobile purification device for purifying indoor air and/or fresh air, has a holder and a filter element having a particle-filtering and a gas-adsorbing region, the particle-filtering region having a filter medium and the filter element being received in the holder to purify indoor air and/or fresh air containing smoke and/or particles and is useful as a mobile purification device, filtering particle-polluted and/or smoke-polluted indoor air and/or fresh air as effectively as possible, with particulate, emitted contaminants being prevented as far as possible from being discharged from the gas-adsorbing region into a space, wherein the particle-filtering region faces a downstream side of the holder and in that the gas-adsorbing region faces an upstream side, which can be supplied with indoor air and/or fresh air polluted with smoke and/or particles.

Abstract: A method of operating a display device of a vehicle is provided on which information is representable in list form with a number of list entries, while the display device size is given and the type and font size are predefined. Each list entry has a second number of maximally representable characters. For the first number of list entries currently to be represented on the display device, it is determined whether, in each case, two mutually successive list entries each have a number of characters that is greater than the second representable number. In the affirmative case, the representable second number of characters of the mutually successive list entries is compared with respect to distinctiveness. When an indistinctiveness is determined, a distinctiveness of these two list entries will be established on the display.

Abstract: A printer (1) with a toner-based printing device, the printer (1) comprising at least one air outlet (2), to which a filter (3) is fastened exchangeably, for the outflow of the gas contained in the printer (1) into the surroundings, the filter (3) comprising at least one electrostatically active filter ply (4).

Abstract: A cartridge filter includes a folded package including filter material and a frame holding the folded package. The frame includes a plurality of profiled strips having identical profiles, and each having two ends. The frame also includes a plurality of corner joints, each disposed at an end of a respective profiled strip. Each corner joint includes an end cap for engaging pair wise with an end cap of an adjacent one of the plurality of corner pieces.

Abstract: The invention relates to a cassette filter, especially a filter for fine or suspended matter from a folded package of filter material fitted in a frame. Said frame comprises profiled strips (1) of identical design and corner connectors (6, 7) that retain the end pieces (20, 21) of the profiled strips (1). The corner connectors (6, 7) are provided with end caps (12, 13) that can be superimposed pair-wise at a right angle.
