Abstract: A hinge to pivotably connect a motor vehicle door to a body of the motor vehicle. The hinge includes a bolt, a first hinge half rotationally connected to a bolt, a second hinge half, a bushing, composed of an electrically insulating material, arranged on the second hinge half to rotationally connect the second hinge half to the bolt, and an electrically conductive component arranged between the bolt and the second hinge half to bridge the bushing and facilitate electrical contact between the bolt and the second hinge half.

Abstract: A static mixer includes profiled layers which are arranged in a ring space and which contain mutually crossing flow channels which are inclined relative to a central axis. A fluid mixture is to be transported in the axial direction in the presence of a mixing action. Each layer extends over a surface which forms a closed or largely closed periphery transverse to the axis. Each layer comprises equivalent channels which extend on an inner or outer side of the layer over at least approximately equally long distances from a first to a second cross-section of the ring space, so that each channel imposes an azimuthal velocity component onto the fluid mixture which flows through it which is substantially equally large for all equivalent channels.

Abstract: The static mixer comprises profiled layers (1, 2) which are arranged in a ring space (3) and which contain mutually crossing flow channels (14, 24) which are inclined relative to a central axis (z). A fluid mixture (4) is to be transported in the axial direction in the presence of a mixing action. Each layer extends over a surface which forms a closed or largely closed periphery transverse to the axis (z). Each layer comprises equivalent channels (14, 14′, 24 and 24′ respectively) which extend on an inner or outer side of the layer over at least approximately equally long distances from a first to a second cross-section of the ring space, so that each channel imposes an azimuthal velocity component (40, 41) onto the fluid mixture which flows through it which is substantially equally large for all equivalent channels.

Abstract: A packing as a porous body for burners, in particular for heating systems, is provided with a housing having an inlet for a gas/air mixture as a combustable gas mixture, a combustion chamber, an ignition device in the combustion chamber and an exhaust gas outlet. The combustion chamber is at least partly filled with a three-dimensional ordered packing of heat resistant ceramic material, foil material, or sheet metal material having continuous hollow cavities for the formation of a defined flame zone.

Abstract: To permit a continuous production of foamed blast furnace slag, a revolving conveyor is provided, which is continuously supplied with a stream of slag from a slag feeder in a trough which comprises a bottom and side walls rising from the bottom. Adjacent to the slag feeder, stationary tubular lances extend in said trough closely above the bottom in the direction of conveyance and are formed in a predetermined length portion with radial outlet orifices for a discharge of water into said trough.

Abstract: The dental sleeve has a cylindrical or a cylindrical and conical shape having a height and circumference corresponding to that of the tooth stump or model to be enclosed. In terms of material, it is a composite foil which includes at least two layers and in which the inner layer, and optionally also the outer layer, consists of fine gold or a gold alloy, while the other layer or layers consist of platinum, palladium, silver, indium or iridium or of alloys of such metals or of alloys of such metals and gold. The cylindrical shape is produced by spot-welding the inner gold layer on the two narrow sides of the foil with a special welding technique. The dental sleeve is used as a carrier for a composite ceramic crown.
