Abstract: An automobile rear lighting includes a first emitter that emits a first light through a cover and a second emitter that emits a second light, different from the first light, through the cover such that an output light including the first light and the second light is emitted through the cover. The automobile rear lighting also includes a driving apparatus. The driving apparatus provides a first driving current to the first emitter and a second driving current to the second emitter. The driving apparatus adapts a magnitude of the first driving current and the second driving current based on at least one of at least one property of the cover or at least one optical component of the automobile rear lighting and a pre-defined color coordinates specification for the output light.

Abstract: A grinding member is formed as a shape-elastic monolithic element and has at least partially a three-dimensional cell structure on a grinding surface of the grinding member. The grinding surface has a first abrasive agent. The grinding surface has at least partially an open-cell structure with open cells. The open cells of the grinding surface communicate via passages with cells of the interior of the grinding member. The cells in the interior of the grinding member that communicate via passages with the open cells of the grinding surface contain a second abrasive agent.

Abstract: An abrasive element support having an axis of rotation and a fastening surface for attachment of an abrasive element is designed as a self-sucking device in the form of a radial fan device. The fastening surface has a fastening element such as a hook and loop fastening element that allows passage of grinding particles in a direction parallel to the fastening surface. The radial fan device has intake and exit openings, wherein the intake opening is arranged closer to the axis of rotation than the exit opening. The intake and exit openings communicate through at least one acceleration chamber of the radial fan device.

Abstract: An abrasive belt for a belt grinding machine has a support layer, an intermediate layer connected to the support layer, and an abrasive layer connected to the intermediate layer. The support layer transmits a drive output of the belt grinding machine onto the abrasive layer. The abrasive layer allows flow of grinding particles through the abrasive layer. The intermediate layer also allows flow of the grinding particles through the intermediate layer, and the support layer allows flow of the grinding particles through the support layer.

Abstract: A device for releasably connecting first and second rods together is characterized by a connecting flange mounted on one end surface of the first rod by a self-tapping screw. The flange includes at least one latch projecting from a surface thereof to engage a recess in the first rod in a form-locking manner. With the flange mounted on the end of the first rod, the first rod is connected with a side of the second rod so that the rods have perpendicular longitudinal axes. The second rod contains a groove along its side in which a pair of nuts are retained. Fastening screws pass through grooves in the first rod, through openings in the flange and into tap holes in the nuts to threadably connect the first rod with the second.
