Abstract: An x-ray system includes an x-ray source which, when in operation, generates x-rays at a plurality of x-ray focal spots, with a collimator allocated in each case to each x-ray focal spot. The collimator selects x-rays generated in the respective x-ray focal spot and directed onto a common detector, collimators being in a fixed position in relation to the respective allocated x-ray focal spots. The x-ray source is embodied as an x-ray tube with at least one anode including the x-ray focal spots and with a plurality of cathodes. Or the x-ray source includes a plurality of x-ray tubes, the anodes whereof include the x-ray focal spots. The collimators are arranged in the respective x-ray tube, and the collimators are arranged on the respective anode. A method is further for operating such an x-ray system.

Abstract: An x-ray anode for an x-ray emitter has a structured surface provided for impingement with electrons. According to an embodiment of the invention, the structured surface has a surface structure which alternates periodically at least in sections and which varies in the micrometer range with respect to its depth extension and periodicity.

Abstract: An ink writing implement having a writing tip, an ink reservoir and a housing component enclosing the ink reservoir, includes a molded, ink delivery unit having a plurality of disc-shaped walls, a plurality of ring-shaped pressure compensation chambers, a flat area, an ink feed channel formed by the flat area, and a parting plane extending through the flat area.

Abstract: A device for filling a converter with writing fluid, including a connector designed to be sealingly engaged with the orifice of a converter. The connector has an orifice in the shape of an orifice of a conventional ink cartridge. The device also includes a pipe-shaped conduit segment, connecting to the connector and extending into the interior of a reservoir containing writing fluid. The pipe-shaped conduit segment extends from the connector in an inclined fashion to a free end proximate to the bottom of the reservoir.

Abstract: A child's safety seat to be fastened to a safety belt system of a motor vehicle, having a pelvic belt and a shoulder belt, is provided. The child's safety seat comprises an under frame and a seat shell. The under frame is to be fastened by the pelvic belt. The seat shell is provided with an integrated safety belt for securing the child in the safety seat. At the foot end of the seat shell an essentially vertically extending hoop is provided which is adapted to rest at the back rest of a vehicle seat. At the bottom portion of the hoop the under frame is engaged by the pelvic belt. The hoop is provided with a guide for the shoulder belt above the center of gravity of the seat shell.
