Abstract: A method and system for monitoring the quality of fluids, wherein comprising the different features of a fluid with at least two different methods are measured and a measure for the quality of the fluid is derived and/or a process of the fluid deterioration is identified by comparing the results of the measurements of the at least two different methods, where the methods includes at least one optical absorption measurement and at least one electron paramagnetic resonance measurement.

Abstract: A method and arrangement for utilizing waste heat that includes a waste heat exchanger, at least two turbines, at least two recuperators, at least two cooler units, and at least two pumps and/or compressors as components, wherein all components are arranged in a single fluid cycle, where the waste heat exchanger heats up a fluid with heat from a waste heat source, the heated fluid flows through a first set of the at least one turbine, the at least one recuperator, the at least one cooler unit, and the at least one pump and/or compressor, and then flows through at least a second set the at least one turbine, the at least one recuperator, the at least one cooler unit, and the at least one pump and/or compressor with the same components arranged in series downstream of the first set.

Abstract: The present invention relates to an arrangement (1) and method for the utilization of waste heat comprising at least a waste heat exchanger (3, 3?, 3?), at least two turbines (6, 6?, 6?}, at least two recuperators (7, 7?, 7?), and at least a cooler unit (8, 9, 8?, 9?, 8?, 9?) in at least one fluid circuit. A pump and compressor (10, 10?, 10?) in one device is comprised, switchable between a pump and compressor function by a change of the rotational frequency of a rotor of the device.

Abstract: A bearing housing of a hydrodynamic foil bearing assembly has an opening for allowing flow of a fluid into the bearing housing. Also included in the a hydrodynamic foil bearing assembly is at least one foil having at least one opening and defining a cylindrical hollow space for receiving a rotating shaft therein. Fluid is supplied from the opening of the bearing housing to a gap between the at least one foil and the rotating shaft through the at least one opening of the at least one foil to form a pressurized fluid film therein.
