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
