Abstract: A settling or sedimentation tank including inlet structures arranged, through whose inlet opening the suspension to be separated flows to the tanks, the height of which can be variably adjusted. In addition to the height variability of the inlet opening, the volumetric flow flowing out of the inlet structure can, depending on the actual load, be directed by forming a horizontally flow-through inlet opening or a vertically flow-through inlet opening and can optionally be divided into horizontal and vertical partial flows QI and QII. As a result of the horizontal inflow, the capacity of the sedimentation tank increases at high loads, and as a result of the vertical inflow, the volume flow through the sedimentation chamber and the turbulent energy in the sedimentation chamber decrease at low loads, so that the retention of fine suspension in the sedimentation tank is increased and thus the effluent quality is improved.

Abstract: An NMR probe head (1) having an RF coil arrangement (2a) in a coil region (2) and an RF shielding tube (3) for supply lines leading from a connection region (4) to the coil region. An elongated backbone (5) is arranged inside the shielding tube and has an inherently rigid, mechanically stiff structure having continuous bores and/or connecting channels (5a) which run parallel to the tube axis and accommodate the supply lines. The backbone has a continuously electrically conductive outer surface which leads from the connection region to the coil region and is electrically conductively connected to the conductive inner surface of the shielding tube via connecting elements (6). A continuous electrically conductive contour is formed thereby between the backbone and the shielding tube. This shields against externally incident RF fields and spatially separates the stable mechanical supporting construction and the supply lines from the electronic and RF components.

Abstract: In order to keep the base surface of a cleaning system for industrially manufactured components as small as possible, it is provided that the process chambers (4, 5, 23) and the robot chamber (3) of the cleaning system are disposed on a base plate (7), wherein the base surface (8) of the base plate (7) is greater than the common base surface (9) of the process chambers (4, 5, 23) and the robot chamber (3), and at least two spatially separate hollow spaces (10, 11, 20) to accommodate the process fluids being provided in the base plate (7), wherein the hollow spaces (10, 11, 20) in each case extend at least partially below the process chamber (4, 5, 23) and extend at least partially outside the common base surface (9) of the process chambers (4, 5, 23) and the robot chamber (3), and at least one hydraulic component of a hydraulic circuit is disposed on the base plate (7) above at least one hollow space (10, 11, 20).

Abstract: A nuclear magnetic resonance (NMR) magic angle spinning (MAS) probe head (1; 61) for measuring a measuring substance in an MAS rotor (21a-21c), comprises a bottom box (3) and a tube (2) mounted to the bottom box (3) and projecting from the bottom box, wherein, in the area of the end (5) of the tube (2) facing away from the bottom box (3), an MAS stator (7; 62) is disposed within the tube (2) for receiving an MAS rotor (21a-21c), and with a pneumatic sample changing system for supplying and discharging an MAS rotor (21a-21c) to/from the MAS stator (7; 62). A transport conduit (10) is provided for pneumatically transferring an MAS rotor (21a-21c) within the transport conduit (10), wherein the transport conduit (10) extends in the inside of the tube (2) from the bottom box (3) to the MAS stator (7; 62). The probe head realizes fast change between different MAS rotors and facilitates RF shielding and keeping of defined extreme temperature conditions.

Abstract: A separation level is formed between the heavy phase and the light phase in a gravitational sedimentation basin. In the case of a centrally arranged inlet construction, said inlet has a substantially horizontally cross-flown cross-section, whereby the level of said cross-section can be continuously adapted to the separation level. Optionally, the vertical dimension of the cross-section of the inlet can also be adjusted. The inlet can also be arranged on the edge, where it can be adapted to the separation level either continuous or in stages. By adaptively adjusting the inlet, the mixing behavior of the suspension flow is improved, whereupon the separation performance of the sedimentation basin and the discharge quality is also improved.
