  • Patent number: 6551386
    Abstract: The invention relates to an oxygen separation device comprising a housing, in which a membrane body separates a first chamber from a second chamber. The membrane body comprises several first channels and several second channels. The channels are arranged in the housing in such a way that their ends on one side of the membrane body are exposed to the first chamber, while their ends on the other side of the membrane body are exposed to the second chamber. In all first channels, the ends exposed to the first chamber are open, and the ends exposed to the second chamber are closed. In all second channels, the ends exposed to the first chamber are closed, and the ends exposed to the second chamber are open. The walls of the channels are formed by an oxygen transport membrane of the membrane body.

  • Publication number: 20020129708
    Abstract: The invention relates to an oxygen separation device (1) comprising a housing (2), in which a membrane body (7) separates a first chamber (9) from a second chamber (10). The membrane body (7) comprises several first channels (16) and several second channels (17). The channels (16,17) are arranged in the housing (2) in such a way that their ends on one side of the membrane body (7) are exposed to the first chamber (9), while their ends on the other side of the membrane body (7) are exposed to the second chamber (10). In all first channels (16), the ends exposed to the first chamber (9) are open, and the ends exposed to the second chamber (10) are closed. In all second channels (17), the ends exposed to the first chamber (9) are closed, and the ends exposed to the second chamber (10) are open. The walls of the channels (16,17) are formed by an oxygen transport membrane (13) of the membrane body (7).

  • Patent number: 6402476
    Abstract: A turbine blade and a method for its production. In order to protect the turbine blade from being damaged by particles carried in the gas, surfaces of the turbine blade are melted down to a predetermined depth in order to form a defined amorphous region on a crystalline structure of a base material. The surfaces are then cooled down at a predetermined temperature reduction rate per unit time.

  • Patent number: 5809056
    Abstract: A Deglor furnace includes heating elements each having a heater rod being surrounded by a protective tube. The protective tube is mounted on a ceiling of the Deglor furnace and is run through an opening in the ceiling into the interior of the Deglor furnace. Heat insulation of the ceiling which borders the opening is protected against corrosive gases from the interior by a shield.

  • Patent number: 4800143
    Abstract: A high-temperature storage battery includes a housing and a stack of at least two storage cells disposed in the housing. Each of the storage cells has components loosely disposed on top of one another in the stack. The components include two reactant chambers, a planar ion-conducting solid electrolyte mutually separating the reactant chambers, and planar components serving as electrodes and bordering the storage cells toward the outside. At least one common resilient structural element presses the components of all of the storage cells together in a leakproof manner.
