Abstract: The present disclosure relates to a method for the pyrometallurgical smelting of metal-containing raw materials, waste materials and/or secondary waste materials (M), wherein these are fed in shredded form to a smelting unit (1) which includes a smelting zone (6), a main reaction zone (7) and a secondary reaction zone (8) and are smelted in the presence of an oxidizing, reducing and/or inert gas and/or gas mixture (G), such that a liquid melt phase (9), a liquid slag phase (10) and a gas phase are formed. The oxidizing, reducing and/or inert gas and/or gas mixture (G) is supplied in compressed form via at least one injector (11) and is expanded adiabatically within the smelting unit (1) and is then injected as adiabatically expanded gas and/or gas mixture into the liquid slag phase (10).

Abstract: A method for working a first component and a second component comprises the following steps: providing the first component, which comprises a thermally sprayed electrically conductive layer, providing the second component, which has a longitudinally extended strip of copper, which at least in a first region has a thickness transversely to the longitudinal direction of more than 0.1 millimeter, arranging the strip and the layer one on top of the other, so that the first region of the strip and the layer have a contact region in common with one another, emitting a laser beam onto the contact region and forming a welded connection, which connects the strip and the layer to one another.

Abstract: An apparatus for a heating device for a vehicle comprises a layer stack which, in a stacking direction, has a heating conductor layer, an electrically conductive layer which forms a contact region, wherein a contour in a projection in the stacking direction of the electrically conductive layer is prespecified, in order to prevent a hotspot on the electrically conductive layer, by at least one of a prespecified width of a front side of the electrically conductive layer which faces a central region of the heating conductor layer, a prespecified distance from a joint of the heating conductor layer, and a prespecified curvature of the contour.

Abstract: An osteosynthesis system includes a bone plate and a segment. The bone plate includes a plurality of passages for bone screws and at least one web. The segment includes at least one passage for a screw. The segment has a clip-like configuration and can be snapped onto the web of the bone plate. The segment also has an upper half and a lower half and is fastened on the web of the bone plate with a force-locked connection by moving the upper and lower halves toward each other. The upper and the lower halves are moved towards each other by introducing a screw into the at least one passage of the segment.

Abstract: Process for the electrolysis of Al2S3, using a bath of molten salt, preferably a bath of molten chloride salt, in which Al2S3 is dissolved characterized in that measures are taken to improve the electrical conductivity of the bath, so as to enable an increase in the current density in the bath.

Abstract: Liquid filter for a motor vehicle and method of venting the filter. The filter includes a venting arrangement adapted to vent air displaced from a filter. The venting arrangement has a first vent nozzle and a second vent nozzle. The first and second vent nozzles are arranged in series along an air flow direction. The first and second vent nozzles provide flow resistance to liquid flow. The method of venting includes arranging the first vent nozzle above the second vent nozzle and spacing the first and second vent nozzles from each other to provide greater resistance to fuel flow than to air flow. This abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: The invention relates to a liquid filter for motor vehicles, i.e. a fuel filter for an internal combustion engine, comprising an air purging device for the air which is driven out of the filter when there is an increase in the volume of liquid. Said air-purging device comprises a hole having low air resistance and high liquid resistance. A second such device is provided and the two holes are successively arranged in the direction of the air flow.
