Abstract: A pump comprises: at least one rotor rotatable about an axis of rotation; a pump housing surrounding the rotor, wherein a pump channel is formed between a radially inner surface of the pump housing and a radially outer surface of the rotor; and a seal assembly that seals the pump channel to an end surface of the rotor. The seal assembly comprises: a sliding surface which is provided on one of the rotor and the pump housing and which extends perpendicular to the axial direction of the rotor; a static surface provided on the other of the rotor and the pump housing; and a first elastomer element attached to the static surface and pressed against the sliding surface in the axial direction.

Abstract: A material-providing system for a manufacturing installation for providing box-shaped load carriers, that is transportable by a driverless transport system. The material-providing system has a rack system having a front side and a rear side, and the rack system forms a magazine shaft, or at least two magazine shafts, for storing load carriers. The at least one magazine shaft extends, starting from the rear side of the rack system, to the front side of the rack system. On the front side of the rack system, the material-providing system has a motorized transfer system for transferring the load carriers to the manufacturing installation, which transfer system is mechanically connected to the rack system and by a transfer system the load carriers can be automatedly removed from the at least one magazine shaft and can be automatedly positioned along the front side of the rack system.

Abstract: Method for influencing noise, wherein a noise source (16), in particular an engine in a motor vehicle, generates the noise with a substantially periodically variable excitation, and wherein a reference variable which is characteristic of the noise source, in particular an engine speed, is present at predetermined successive supply instants (ti), comprising the method steps; reading out at least a first value (Ni?1) of the reference variable at a first supply instant (ti?1) and a second predetermined value at a second supply instant (ti); generating the reference signal (12) at at least one instant (t) between the second supply instant (ti) and a third supply instant (ti+1) as a function of the first and second values that were read out; and sending the reference signal (12) to a device for actively influencing noise (11), which generates activation signals (13) for at least one actuator (14) as a function of the reference signal (12), wherein the at least one actuator (14) emits compensation sound, which inte

Abstract: The cabinet comprises a case carrying a plurality of slidably mounted drawers. At the back of the drawers a latch bar is vertically oriented and pivotal between latch and unlatch positions. The bar has a flange which fits into keeper structure on a clip protruding from each drawer in the latch condition. A camming surface on each clip moves the latch bar to a latch position after one drawer is withdrawn so that none of the other drawers can be withdrawn. As the drawer is closed, another camming surface on the clip moves the latch bar back to an unlatch position. To insure alignment of the last mentioned camming surface with the latch bar, a slot is provided in the clip on each drawer which slot is aligned with an alignment flange attached to the case.

Abstract: Shelving apparatus includes a pair of spaced-apart support posts, each post having two back-to-back plates of different widths cooperating to define a recess for receiving therein one end of an associated closure panel extending between the posts, two longitudinally extending parallel rows of openings in the plates, corresponding openings in the two rows being aligned transversely of the plates, first and second shelf clips respectively disposed on opposite sides of each post in horizontal alignment with each other, each clip having a hook-shaped finger extending therefrom adjacent to one side edge thereof and an aperture therethrough adjacent to the other side edge thereof, the clip being disposed in use with the finger extending through a selected opening in one of the rows for latching engagement with the associated post and with the aperture disposed in registry with the transversely aligned opening in the other row of openings, the apertures being dimensioned and arranged freely to accommodate the attach
