Abstract: An exhaust gas turbocharger may include a shaft mounted in a bearing housing carrying a compressor wheel and a turbine wheel. The shaft may include a sealing bush arranged on the shaft in a rotationally fixed manner. The sealing bush together with a bearing housing cover may at least partially delimit an annular oil centrifuging space arranged coaxially to the sealing bush. The bearing housing cover may include a guiding nib located radially outside the sealing bush partially covering the sealing bush in axial direction. The guiding nib may be configured to guide oil separated in the oil centrifuging space onto the rotating sealing bush. The rotating sealing bush may be configured to direct the oil into the oil centrifuging space in response to centrifugal force creating an oil swirl.

Abstract: In a method of decomposing partially fluorinated and perfluorinated surfactants which are, in particular, present in wastewater, sewage sludges and the like, the surfactant is present in solution or suspension and is electrolytically decomposed. An anodic oxidation of the surfactants preferably takes place here. The method is particularly suitable for decomposing perfluorinated alkylsulfonates, in particular PFOS. The invention also describes an apparatus for electrolytically decomposing partially fluorinated and perfluorinated surfactants.

Abstract: The present invention relates to an exhaust system for a combustion engine, particularly of a vehicle, with an oxidation catalytic converter (oxicat), with an electrically heatable catalytic converter (E-cat) arranged upstream of the oxicat and with a fuel injector arranged upstream of the E-cat. An energetically favourable mode of operation is achieved when a particle filter is arranged downstream of the oxicat, when a bypass path bypassing the E-cat commences downstream of the fuel injector and ends upstream of the oxicat and when the E-cat is designed for a smaller exhaust gas flow rate than the oxicat.

Abstract: A method for regenerating a diesel particle filter (18) of an exhaust system in which an exhaust gas flow from a diesel engine is fed through the diesel particle filter (18). The system further includes at least one of a burner (34) for heating up the exhaust gas flow, a controllable air supply (36) and a metering device (40) for introducing hydrocarbons into the exhaust gas flow being fed to the diesel particle filter (18). The method includes registering at least one of an exhaust gas temperature and an oxygen content of the exhaust gas at least one of upstream and downstream of the diesel particle filter (18), selecting and activating at least one of the burner (34), the air supply (36) and the metering device (40), and controlling the selected component as a function of the registered at least one of exhaust gas temperature and oxygen content.

Abstract: In a method for producing plastic sanitary articles having surfaces metallized by electroplating, the sanitary article has at least one electrically nonconductive component, before said article is metallized by electroplating using an external current source. This component at least partially decouples the water-bearing regions of the sanitary article from the current flow during metallization by electroplating using the external current source. The component is preferably a separate component which can be reversibly connected to the sanitary article. The invention also includes the component for decoupling the current itself, and a sanitary article which is provided with the component.

Abstract: A sanitary fitting (1) has a housing (2), an outlet (3) and functional parts (4) for carrying water. In this case, the outlet (3) is formed on the housing (2) or is connected or can be connected to the housing (2). The functional parts (4) are preferably arranged inside the housing (2). In the case of this sanitary fitting, as claimed in the invention the outlet (3) is substantially free from water-carrying functional parts (4), and at least the outlet (3) and preferably also the housing (2) are produced substantially completely from glass.

Abstract: The invention relates to a method for coating objects, particularly plumbing fixtures, having metallic surfaces. According to the method, at least one organosilane is applied during the so-called sol-gel process after an optionally provided pretreatment step that serves to activate the metallic surfaces, and the coating obtained thereby is transformed into a polysiloxane coating. This transformation of the coating into a polysiloxane coating preferably ensues by a thermal treatment effected at temperatures of <100° C., preferably <70° C.

Abstract: In the case of a method for producing decorative surface structures, patterns or the like on articles, in particular sanitary articles, basic bodies made of a first metal, basic bodies made of metal that are coated with a first metal or basic bodies made of plastic that are coated with a first metal are used as a basis. Then, a layer of material temporarily applied to the article is partially removed by electromagnetic radiation or by particle radiation, thereby forming a first surface structure with regions that are free from material. Subsequently, the first metal is at least partially removed in the material-free regions or the first metal or some other metal is built up in the material-free regions. This method step is followed by removal of the still present material, a second (final) surface structure being formed. Finally, further top layers can preferably be applied to the article, the second surface structure being substantially retained.

Abstract: The invention relates to an injector for injecting fuel into a combustion chamber. The injector comprises at least one spray orifice with an inlet opening and an outlet opening. The spray orifice has a device for specifically producing cavitation at the outlet opening in order to remove deposits from the outlet opening that are produced during operation.

Abstract: The invention relates to a method for coating objects, particularly sanitary ware such as plumbing fixtures, shower fittings and the like, during which at least one layer made of copper, nickel or of a copper-nickel alloy is firstly applied to the object. The object itself and/or at least the uppermost applied layer are/is then subjected to a mechanical surface treatment, and at least one nickel-tungsten layer and/or at least one palladium-nickel layer are/is applied to the object or the surface-treated layer. The surface treatment preferably ensues by brushing and/or blasting. This enables objects to be provided with a specific appearance, particularly a high-grade steel-like appearance.

Abstract: In a method for the hydro-erosive rounding of an edge of a part, particularly an edge in a duct of a high pressure-resistant part, and a use thereof, a liquid to which abrasive elements are added is directed along the edge that is to be rounded. In order to optimize the result of the rounding process, a high-viscosity liquid is used as a liquid (10). The inventive method is used for rounding parts of a fuel injection system.

Abstract: In a method and a device for the hydro-erosive rounding of an edge of a component, in particular, an edge in a channel of a high-pressure resistant component, a fluid charged with abrasive bodies is run along the edge for rounding and the flow speed in the vicinity of the edge for rounding is increased by means of a body arranged in the fluid flow path. With relation to the method, the flow speed of the fluid (6) is increasingly raised along the course of the body (7) until the edge (5) for rounding is reached by means of the geometry of the body (7) and, with relation to the device, the cross-sectional area of the flow channel (10) continuously declines in the direction of flow (S) of the fluid (6) along the length of the body (7) at least as far as the edge (5).
