Abstract: A wheel hub includes an outer collar region, as seen in the radial direction, and an inner core region, as seen in the radial direction, wherein, as seen in the axial direction, the inner core region is thicker than the outer collar region, and wherein, in the inner core region, the wheel hub has a substantially axially running primary recess for the connection of a brake disk.

Abstract: The invention relates to a process for concentrating diluted sulfuric acid (10) which may comprise at least one nitroaromatic compound and/or nitric acid as impurities, comprising: (a) feeding the diluted sulfuric acid (10) into a first stage (1) in which low boilers are removed by evaporation and/or stripping to obtain a first concentrated sulfuric acid (12); (b) optionally feeding the first concentrated sulfuric acid (12) into a second evaporation stage (2) to obtain a second concentrated sulfuric acid (14); (c) feeding the second concentrated sulfuric (14) acid into a third evaporation stage (3) if step (b) is carried out, or feeding the first concentrated sulfuric acid (12) into the third evaporation stage (3) if step (b) is not carried out, to obtain concentrated sulfuric acid (16) as product, wherein an oxidizing agent (17) and/or a precursor of an oxidizing agent is fed into the third evaporation stage (3).

Abstract: A feed supply unit comprising (a) a feed dosage unit for supplying a viscosity unstable liquid feed to a reactor, (b) a flushing unit for flushing at least a part of the feed dosage unit according to (a) with a flushing medium, and (c) a signal transmission means for transmitting a signal from a monitoring means to a control means.

Abstract: A wheel hub for a utility vehicle includes a brake element abutment surface against which a brake element bears in an installed state, and a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state, and/or a receiving region for a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state.

Abstract: A filter holder for receiving filter cassettes (19) and a method for sterilizing the filter are provided. The filter holder has first and second parallel plates (3, 4). The first plate (3) is fixed and the second plate (4) is movable along at least one rail (2) by a drive (7, 9) so that the filter cassettes (19) can be clamped between the plates (3, 4) with a predefined clamping pressure. The drive (7, 9) is designed to be removable. The at least one rail (2) has at least one tension rod (5) with a spring clamping element (6) so that the first and second plates (3, 4) can be clamped with a pre-definable pressure against the filter cassettes (19).
