Abstract: A nasal cannula for supplying respiratory gas to a patient in the context of high-flow therapy comprises a nose attachment piece having a hollow main body, a hose connector for connecting a supply hose to the main body, such that respiratory gas can flow from the supply hose into the main body, and two nose pieces projecting from the main body, for conducting the respiratory gas from the main body into the nose of the patient; a first cheek pad for supporting and/or fixing the nose attachment piece on a first cheek of the patient; a second cheek pad for supporting and/or fixing the nose attachment piece on a second cheek of the patient; a retaining band, which can be tensioned around the head of the patient, for applying an additional retaining force to the nose attachment piece and/or the two cheek pads.

Abstract: The method and the device serve to treat the flue dust formed during the production of nonferrous metals. After the addition of sulfur and/or a sulfur compound, the flue dust is heated, and volatile compounds are separated in a downstream offgas treatment unit. The flue dust is heated in an inert atmosphere.

Abstract: A process for electrolytic production of fine-grained, single-phase, metallic alloy powders, especially powders of intermetallic compounds as well as noble metal alloy powders, is described in which powdery metallic precipitates are galvanically produced on the cathode from an electrolytic precipitating bath known in the art, which contains in solution the metals to be precipitated, under electrolysis conditions causing a powder precipitation known in the art. For the production of alloy powders with defined properties, it is determined, first in preliminary tests by gradual increase of the cathode potential with otherwise constant process parameters, the minimum cathode potential at which single-phase alloy powders result and then the powder precipitation is potentiostatically performed in a cathode potential at or above the minimum for the single-phase alloy precipitation.
