Abstract: A cooling device for x-ray tubes in x-ray generators, comprising a housing with a central receiving device for receiving an x-ray tube with an inlet opening for supplying a gaseous coolant, an outlet opening for discharging the gaseous coolant, and a gas-conducting channel which extends between the inlet opening and the outlet opening. The gas-conducting channel is designed to conduct the gaseous coolant directly by the high-voltage x-ray tube housing during operation. The gas-conducting channel additionally extends in a helical manner about the x-ray tubes such that the electric potential applied to the x-ray tubes drops to zero potential along the gas-conducting channel.

Abstract: An inspection of containers for impurities, using a radiation source. The radiation source is designed to emit radiation that radiates through a container to be examined. The device also comprises a detection element which is designed to detect the radiation that has been emitted by the radiation source and has radiated through the container. The device further comprises an evaluation element which is designed to evaluate the radiation detected by the detection element. An identification element comprising an optical watermark is arranged in the optical path between the radiation source and the detection element.

Abstract: The invention related to a device for examining filled containers for foreign bodies. In an embodiment, the device for examining filled containers for foreign bodies has a transport apparatus for transporting the containers individually in succession in a row on a plane of transport, at least one X-ray source which emits X-rays in a predetermined direction, and an apparatus for recording the X-rays after they have passed through the containers. In an embodiment, the direction in which the X-rays are emitted from the X-ray source is inclined by between 10° and 60° to the plane of transport. In an embodiment, two X-ray sources are provided, namely one arranged above and one below the plane of transport. In an embodiment, the X-ray source is positioned such that the ray course is approximately tangential to the maximum slope of the bulge of the container bottom.

Abstract: An invention related to an X-ray device for the generation of brief X-ray pulses comprising an X-ray tube having a thermionic cathode and an anode and an X-ray generator having a first circuit for the generation of a high-voltage pulse which is applied to the anode for the generation of the X-ray pulse. The X-ray generator further comprising a second circuit by which a low voltage is continuously applied to the anode which pre-heats the X-ray tube and is at most sufficient for the generation of low-energy X-radiation. The first circuit can have a high-voltage power supply unit which charges a high-voltage capacitor which can be applied to the anode via a high-voltage switch. The first circuit can be a Marx generator. There may be only one power supply, which both generates the continuously low voltage and also drives the Marx generator for the generation of the high voltage.
