Abstract: A clutch actuation device, particularly for a manual transmission of a vehicle, in particular a commercial vehicle, includes a clutch actuation setting device that can be placed in various settings, based on which a corresponding actuation of the clutch takes place. The clutch actuation setting device is suitable for generating electrical signals as a function of the setting, based on which the clutch is correspondingly actuated. A method controls/regulates such a clutch actuation device, particularly for a manual transmission of a vehicle.

Abstract: Air-demand-controlled compressor arrangement, particularly for commercial vehicles, includes a motor unit for generating a rotating movement which, by way of an interposed rotational-speed-transmitting transmission unit, drives a compressor unit for generating compressed air from ambient air. A control unit triggers the generating of compressed air in the case of a compressed-air demand. The transmission unit is constructed in the manner of a transmission whose rotational speed can be varied, and the control unit interacts with the transmission unit in order to adapt the rotational speed of the transmission unit corresponding to the compressed-air demand.

Abstract: Method and compressor arrangement for generating compressed air, particularly for commercial vehicles, which is generated by way of a compressor unit (3) driven by an internal-combustion engine (1) from the ambient air according to a control unit (14), in which cases, by means of the compressor unit (3) operated by the internal-combustion engine, compressed of only a low pressure level is generated for assigned low-pressure consuming devices (7a, 7b), and in that, starting from the compressed air of the low pressure level, by means of a separate auxiliary compressor unit (8), compressed air of a high pressure level is generated for assigned high-pressure consuming devices (11a, 11b), the coordinated triggering of the two compressor units (3,8) being carried out, in a pressure-demand-controlled manner, centrally by means of the control unit (14).

Abstract: An internal-combustion engine for generating a rotational movement is provided to drive a compressor unit which is connected on the output side, for generating compressed air from ambient air. A control unit triggers the generating of compressed air when compressed air is demanded. An auxiliary compressor unit covers peak demands for compressed air and is fluidically connected in parallel with respect to the internal-combustion-engine-driven compressor unit. The auxiliary compressor unit is driven by an electric motor. The control unit starts the operation of the auxiliary compressor unit in the event of a detected peak demand.

Abstract: A nuclear fuel sintered body is produced from a powder which contains at least one fissile heavy metal oxide. During the further treatment of the powder over the course of the process preceding the sintering operation, a dopant that contains at least 100 ppm of an iron oxide compound is added to the powder. The powder is a UO2-containing powder obtained from a dry-chemical conversion process, and if appropriate, a powder which contains further fissile heavy metal oxide (U3O8, PuO2, inter alia). As a result, the sintered body is provided with high plasticity combined, at the same time, with a large grain size. This advantageously reduces an interaction between the nuclear fuel sintered body and a fuel rod cladding tube during an operation of the reactor.
