Abstract: The invention relates to a vacuum system with a vacuum chamber and a detection device as well as a detection device for a vacuum system. A vacuum system (1) comprises a vacuum chamber (10) with an outer wall (12). The outer wall encloses a volume (15) which can be evacuated. The vacuum system (1) further comprises a detection device (20) with a detection element for detecting waves and/or particles. The detection device (20) is arranged outside the vacuum chamber (10). In this way, high-quality detection can be achieved with little technical effort.

Abstract: The invention relates to a control device for a brake system of a vehicle (10; 92; 132; 238), said vehicle (10; 92; 132; 238) having a supporting structure (222; 240) and a cabin (224; 242) that is supported by the supporting structure (222; 240) and has at least one driver's seat (226). The control device is located outside the cabin (224; 242) on the supporting structure (222; 240) and the control device has additional functionality for controlling an electronic air spring system.

Abstract: The invention relates to a frictionally engaged driving belt having a base body (2) and a cover layer (1) that consists of rubber or a rubber-like synthetic material which is provided with a tractive support layer (3) that is embedded into the rubber or the rubber-like synthetic material. The aim of the invention is to prevent or reduce the generation of noise in drives of the belts. Only the surface or a portion of the surface, preferably the motion-transferring part of the surface, pertaining to the driving belt is provided with a flocking material consisting of short aramide fibers (5). A portion of said aramide fibers (5) is integrated into the surface only with a partial length of each individual fiber.

Abstract: A system and method for minimizing new water use in the water circulation system of a treatment plant in which the matter to be treated is purified and/or disaggregated using water in a treatment step. The suspension containing the remaining components is subjected to mechanical purification and the mechanically purified suspension is separated into two processing water streams. The first processing water stream is supplied back into the treatment step and the second processing water stream is subjected to a chemical-physical clarification. The chemically-physically clarified processing water stream is separated into two clarified water streams. The first clarified water stream is led into one of the two processing water streams and/or into the suspension and the second clarified water stream is subjected to a biological clarification. The biologically clarified water stream, being a fresh water stream, is led into one or two clarified water streams.
