Abstract: Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.

Abstract: A milling roller module for a surface miner, includes a milling roller operating with undershot for loosening the material from the block being mined, a support frame for fastening the milling roller to the surface miner, and a takeup chute for supporting the intermediate conveying of the loosened material in the area of the milling roller and for transferring the material to the downstream discharge belt in a specific manner. The drives are placed into the milling roller and the feed lines are led into the milling roller together with the support frame for fastening the milling roller from the side in the upper third of the milling roller diameter. As a result, it is possible to perform mining operations up to a cutting depth that is equal to half the roller diameter. A takeup chute is provided to transfer the material from the milling roller onto the downstream discharge belt in a specific manner.
