Abstract: Described and depicted is a gas scrubber, in particular for desulphurising flue gases, preferably for installation on a ship, having a scrubber housing and a gas pipe arranged underneath the scrubber housing for guiding the gas to be scrubbed in the scrubber housing, wherein the scrubber housing has a scrubber chamber delimited by a scrubber base, a scrubber head and a scrubber shell provided between the scrubber base and the scrubber head. In order to achieve a more reliable operation, it is provided that a gas supply for the lateral introduction of gas via at least one opening into the scrubber chamber is provided in the region of the scrubber shell.

Abstract: The invention relates to a scalable device for storing and releasing energy, consisting of a housing that can be evacuated, a vacuum (12), at least one flywheel mass (2) on a shaft (17), at least one passive superconducting radial bearing and an electrical machine (24) that constitutes both a motor and a generator, wherein a cold surface is arranged in the vacuum container (11) for stabilizing the vacuum (12). The invention has the advantage that an energy store is provided that operates efficiently and cost-effectively with minimized energy losses, is scalable and also has sufficient safety elements to enable it to be used in industrial environments.

Abstract: A cobalt coincidence radioactivity detector is used to separate radioactive concrete dust from uncontaminated dust resulting from dismantling a nuclear power plant. A suction air stream carries the dust through a vacuum line to a cyclone segregator. The dust falls into a smaller first container from the segregator, and the detector detects radioactivity in the filled first container. The dust is transferred from the first container to a second container if the detected radioactivity exceeds a predetermined threshold. The dust is transferred from the first container to a third container if the detected radioactivity does not exceed the predetermined threshold. A filter collects the dust carried past the segregator by the suction air stream. If the radioactivity detected in the dust that collects on the filter exceeds the predetermined threshold, the dust in the first container is transferred to the second container before the first container is allowed to fill.

Abstract: A single-crystal pulling device includes vertically tilted magnetic coils between the walls of a cooling vessel. The inside and outside walls of the cooling vessel are coaxially aligned about a central axis. The inside wall of the cooling vessel is coaxially disposed around a cylindrical crucible that holds molten semiconductor material. A mid line passes through the middle point of a first coil, the central axis and the middle point of a second coil. The first coil is wound in a first plane, and the second coil is wound in a second plane. The first plane and the second plane both intersect the central axis at the same point. The first plane intersects the central axis at an angle between 5 and 15 degrees. In one embodiment, the first plane intersects the central axis below the crucible. In another embodiment, the first plane intersects the central axis above the crucible.

Abstract: The invention relates to a high-temperature superconductor (HTS) magnet system, preferably for an insertion device for generation of high-intensity synchrotron radiation, consisting of the coil body (6), on the mantle surface of which poles with windings that lie between them are disposed, wherein at least one high-temperature superconductor strip (23) is wound onto the coil body (6) in one direction, and adjacent winding packages or sections are electrically connected with one another in such a manner that the current flow runs in opposite directions, in each instance. The solution according to the invention has the advantage of a simplified winding process, whereby individual coil pairs can be replaced, if necessary, by means of the modular arrangement. The scheme can be applied to every possible configuration of an insertion device, and is therefore also suitable for use in so-called free electron lasers and other light sources based on particle accelerators.

Abstract: A method and system for purifying flue gases from power plants fired with fossil fuels has an absorber with at least one contact installation level arranged in an upper region, impinged with a suspension, and flowed through by untreated gas. The lower region has an absorption suspension sump, above which the inflow for the untreated gas is disposed. A separate reaction container includes two chambers separated by a partition wall with an overflow. The first chamber is connected with the sump, receives oxidation air, and has in a lower region an opening for discharging suspension. The second chamber is connected with a lime/limestone suspension container. A gas exhaust hood above the reaction container draws exhaust vapors into an exhaust vapor hood. A line for absorption suspension extends between at least one spraying level of the absorber and the reaction container, and a process water feed lies above the spraying level.
