Abstract: An apparatus for producing ozone from oxygen includes at least one discharge electrode and counterelectrode which are separated by a dielectric of high heat conductivity and tightly bear on the dielectric that is cooled in a direct manner. The discharge electrode, around which oxygen flows, forms a non-closed surface and is in the form of a wire. By applying an electric field, the discharge electrode triggers a discharge in the gas space surrounding the discharge electrode and on the dielectric. The discharge electrode is made of molybdenum, tungsten, niobium or tantalum and is directly exposed to the oxygen flow.

Abstract: A damping tube-shaped bypass measurement section with protective maintenance features and continuous flow velocity scanning on absorptive filtration units in the nuclear engineering field is disclosed. The bypass measurement section comprises a tube-shaped bypass measurement section, having single or double elements, for absorption filters, featuring at least one shut-off device, and including an absorption layer thickness connected to the main filtration unit which is to be controlled or monitored, and provides for an equivalent absorption layer thickness.
