    摘要: In a process for coating the surface of workpieces, a coating agent is applied to the workpiece and then cured in an electromagnetic alternating field. In order to enable a high-quality surface coating even with standard coating agents, in particular with liquid coatings, despite the short duration of the process, first the volatile components of the coating agent are expelled in an electromagnetic alternating field having a first frequency spectrum. For the purpose of crosslinking and/or curing the remaining coating agent components, the surface of the workpiece is then heated in an electromagnetic alternating field having a second frequency spectrum, the frequency range of which is below the first frequency spectrum.

    摘要: A device for changing processing media has a plurality of supply connections (2) that are arranged on a common carrier (1) and that are displaceable with respect to a tool coupling (3) in a displacement direction (6). Even in the case of a large number of supply connections (2) for the processing media, both a compact design and also a quick change of these supply connections (2) is possible where the carrier (1) is traversed by line segments (4) that, on the one carrier outer side, have supply connections (2) and, on the opposite carrier inner side, have coupling attachments (5) for coupling receptacles (8) of the tool coupling (3) that are arranged on the lateral surface, said tool coupling being mounted so as to be rotatable about an axis of rotation (7) that extends parallel to the carrier (1) and normal to the displacement direction (6).

    摘要: Anapparatus for continuously filtering a sludge suspension, having a hollow shaft (2) that is rotatably mounted in a housing (1) and which that is fluidically connected to an inner chamber (6), which is surrounded by a filter membrane (5), of a discoid filter element (3) that radially protrudes from the hollow shaft (2), for removing a filtrate. A higher throughput of the filtrate, independently of the solids content of the sludge suspension to be filtered, is provided by the filter cake thickness and the filtration duration. The the radius (r) of the filter element (3) increases in the circumferential direction from a low pressure radius ri to a high pressure radius rh,reducing the free housing cross section.

    摘要: An atomizer (1) for a coating composition comprises a coating composition substrate, which is vibration-excited by an exciter (3). Workpieces are provided with a coating of uniform thickness in such a way that resources are saved, and the coating composition substrate is a membrane (2) driven by a rotary drive and supplied with acoustic waves by an exciter (3) to vibrate.
