Abstract: A positioning arrangement for positioning a sheet metal element on a flange joint includes a flange with a medium passage opening, and a mating flange with a medium passage opening. The mating flange is connected to the flange with a plurality of fastening screws and the respective medium passage openings of the flange and the mating flange communicate with each other. The positioning arrangement also includes a sheet metal element with an abutment section. The abutment section is arranged in an abutment plane between the flange and the mating flange around the medium passage openings. The sheet metal element also includes at least three first tabs, which are arranged at a first through-hole of the sheet metal element and project transversely to the abutment plane into a first receiving hole in the mating flange. The at least three first tabs are received with radial clearance in the first receiving hole.

Abstract: A heat engine, in particular an aircraft engine, having a first compressor for supplying a combustion chamber of the heat engine with air and a first turbine arranged downstream of the combustion chamber for driving the first compressor, wherein the heat engine also has at least one steam supply line for supplying steam from a steam source into the combustion chamber. The heat engine also has a steam supply device, which has a second compressor and is designed to compress the working gas further by the second compressor as a function of a mass flow conducted through the steam supply line, before the working gas flows into the combustion chamber.

Abstract: An electrostatic separator or precipitator through which an air stream to be cleaned of particles flows in a longitudinal direction includes at least one electrospray ionization source, which is supplied with a positive potential and can be implemented, for example, by the tips of a graphite fiber bundle, and a collector unit arranged downstream for particle separation and having parallel collector and driver plates. The ion flow from the corona zone is additionally homogenized and spread by an upstream collector element, in particular a collector grid, upstream of the at least one electrospray ionization source, so that high particle separation rates can be achieved with minimal ozone emissions. Alternatively, or in addition, the ion flow from the corona zone can be homogenized downstream of the at least one spray ionization source by one or more border counter-electrodes.

Abstract: A divertor for system supporting high-energy plasma for fusion employs permanent magnets providing far weaker magnetic field strength than conventionally used in cryogenic magnetic systems through an ability to place the permanent magnets in close proximity to the plasma containment volume.

Abstract: An internal combustion engine including a crankcase (1) and including a cylinder head is described, including at least one cylinder block, at least one planar flange surface for accommodating at least one cooler (2), at least one cooler (2), at least one coolant inlet to the cooler (2), at least one coolant outlet (8) from the cooler (2), at least one exhaust gas inlet to the cooler (2), at least one integrated exhaust gas feedthrough from the cooler (2), and at least one internal cooling section (3).

Abstract: An exhaust gas treatment device, an aircraft propulsion system and method for treating an exhaust gas stream are provided. The exhaust gas treatment has a condenser, which condenses at least a portion of water contained in the exhaust gas stream from the turbomachine and thereby releases a first energy; an evaporator, which evaporates at least a portion of the water condensed in the condenser and thereby absorbs a second energy, which is extracted from the exhaust gas stream from the turbomachine; a turbine, which is driven by steam output by the evaporator and expands the steam; a fan, which can be driven by the turbine and feeds the condenser ambient air in order that it absorb the first energy; and at least one exhaust apparatus, out of which the ambient air given off by the condenser and/or a dehumidified exhaust gas stream is exhausted from the condenser.

Abstract: The present invention relates to the field of plant breeding and in particular to the generation of plants from cells and other tissues. More particularly, the invention provides methods and means for improving plant regeneration, especially from transformed or genetically modified plant cells.

Abstract: A guide vane for a turbomachine is disclosed. The guide vane includes a heat pipe wall that is interpenetrated by a capillary system, which has a continuous material transition from a first surface, which delimits the guide vane toward the outside, to a second surface, which lies opposite to the first surface and delimits an evaporation cavity in the interior of the guide vane. Further disclosed is a method for producing a guide vane having a heat pipe wall, wherein at least the heat pipe wall is formed by additive manufacture.

Abstract: A ventilation unit for decentralised room ventilation systems, in which unit at least one reversible fan and a heat reservoir element are supplemented by an electrostatic precipitator for air purification. In addition, a filter assembly is provided for a ventilation system, in particular for a decentralised room ventilation system, having an air duct with an electrostatic precipitator through which an air stream to be purified is forced, with the precipitator extending over a predetermined section of the air duct. The filter assembly has, in the predetermined electrostatic-precipitator section of the air duct, at least one heat reservoir element impinged by the air stream, the electrostatic precipitator and the heat reservoir element thus being spatially restricted relative to one another.
