Abstract: A nutraceutical composition including one or more sources of fiber, glutamine, one or more probiotics, one or more sources of omega-3, and one or more antioxidants, for use in the prevention and/or treatment of dysbiosis of the intestinal microbiota. Also, a method for preventing and/or treating dysbiosis including a step of administering the nutraceutical composition to a patient in need thereof. Further, a three-part kit for use in the prevention and/or treatment of dysbiosis of the intestinal microbiota.

Abstract: A compressor or turbine type rotary machine for compressing or expanding a dangerous gas, e.g. a gas that is toxic or explosive, comprises a closed enclosure formed outside the stator around a shaft passage receiving the shaft of the rotor, the enclosure being delimited by a bell and being filled with a liquid under pressure, a wet type mechanical seal being disposed between the rotor shaft and the stator, inside the stator. The liquid contained in the enclosure is put under pressure, and a magnetic coupling is provided to link the rotor shaft to an outside shaft. The invention makes it possible to prevent any leakage of dangerous gas from the inside to the outside of the rotary machine.

Abstract: A regenerative centrifugal compressor has an impeller disk with axial impeller blades on either side of the impeller disk rim, and a support housing for rotationally supporting a drive shaft for the impeller disk, and also defining annular compression chambers that respectively surround one or the other of the rows of impeller blades. The annular compression chambers extend in the rotation direction of the impeller from an inlet to an outlet, with a stripper section extending from the outlet to the inlet in the rotation direction. Stripper seal inserts formed of a low-friction material softer than the impeller blades are fastened into stripper receptacles on either side of the housing at the stripper section. A baffle at the inlet conducts inlet air around the impeller to a radially inward side thereof. Annular running seals are provided between the rim of the impeller disk and the housing. The blades of the impeller are shaped for optimal efficiency and compression.

Abstract: In and for an installation comprising a fluid source and a plurality of fluid-using receivers to be fed with fluid from said source, a device for supplying fluid from said source to said receivers independently of one another, said device comprising a fluid manifold connected with said fluid source and branching out into a plurality of fluid emission nozzles having each an outlet opening, and a plurality of fluid-receiving pipes each of which is connected with a corresponding receiver and has an inlet opening located in line with and spaced by a gap from the outlet opening of a corresponding emission nozzle, the cross-sectional area of said inlet opening of a receiving pipe being at the very most equal to the cross-sectional area of said outlet opening of said corresponding emission nozzle.
