Abstract: Devices (100) for calming or mixing gases are provided. The devices (100) enable calming and/or mixing with an integrated mixing geometry, integration of sensors and actuators, and optimized conduction as well as provision of the mixed gases. The devises include one or more gas inlets, a gas outlet and a mixing system, including the integrated mixing geometry that is manufactured integrally and gas-tight in a manufacturing or joining process which is based on a formation of a form-fitting and/or force-fitting as well as gas-tight connection of plastic materials and/or metallic materials based on a printing technology or 3D printing technology.

Abstract: The centrifugal filter comprises a rotatable travelling basket (5) disposed within a collector chamber (1). A machine body (2) which can be supported on a support (3) carries a bearing arrangement (8) for the hub (14) of the travelling basket (5). In the travelling basket (5) which partially comprises holes is present a filter element (20) in such a way that during the rotation of the travelling basket the liquid to be filtered can flow out through the filter element (20) and through these holes. For removing the filtrate, retained on the filter element and consisting of solid particles, a lifting device (22) is present which can be moved back and forth. The travelling basket (5) comprises a travelling basket neck (7) connected with the travelling basket hub (14), which neck is provided with passage openings which communicate at least partially with further passage openings disposed in the bottom portion of the machine body (2).

Abstract: A hydraulic control rod drive for a water-cooled nuclear reactor includes a control valve assembly outside the reactor pressure vessel for influencing the fluid quantity on the pressure side of a fluid pump assembly for adjusting control rods in raising and lowering directions and to maintain a control rod position.

Abstract: Tornado flow separator for the thermal treatment of fine-grain or granular material with at least one gaseous medium, including a cylindrical reaction chamber having a surface, two ends and at least first, second and third treatment zones of substantially equal length through which the material passes after given dwelling time, tangential feeding means for the gaseous media being disposed in the surface of the reaction chamber in the treatment zones for setting the dwelling time of the material in the third treatment zone to be at least twice as long as the dwelling time in each of the first and second treatment zones, at least one inclined tangential material feed disposed in vicinity of one of the ends of the reaction chamber, at least one outlet for treatment material disposed in vicinity of the others of the ends of the reaction chamber, and an exhaust pipe for at least one of excess and spent gaseous media being axially extended into the reaction chamber from along side the material outlet and having a f

Abstract: In a tornado-flow vortex generator for separating particulates from gases, having a cylindrical vortex chamber, an inlet tube for raw gas coaxially disposed in the vortex chamber and terminating in a nozzle for providing an advance rotation in a flow of the raw gas therethrough, a hopper diaphragm surrounding the inlet tube and formed, in vicinity of the vortex-chamber casing, with an annular particulate-discharge slot communicating with a space within a hopper, a clean-gas outlet disposed in the vortex chamber spaced from and opposite the raw-gas inlet tube, an auxiliary-gas outlet surrounding the clean-gas outlet, and an auxiliary-gas inlet disposed at the vortex-chamber casing for blowing auxiliary gas into the vortex chamber at an inclination and tangentially to the casing thereof and connected by a blower to the auxiliary-gas outlet, the improvement includes a line having valve means and connecting the hopper space with a location of the vortex generator at which a pressure exists which is lower than the
