  • Patent number: 5743656
    Abstract: A hydrodynamic bearing apparatus comprises at least two hydrodynamic bearing units which rotatably support a rotation member against a fixed member by hydrodynamic pressure of a lubricant filled in a bearing space. A thrust plate is adhesively bonded on one of the rotation member and fixed member to support the rotation member in an axial direction. The thrust plate and rotation member or fixed member form a junction. A mechanical bonding device bonds the thrust plate onto one of the rotation member and fixed member. A sealing agent prevents the lubricant from leaking from the junction between the thrust plate and the rotation member or fixed member. The sealing agent fills a space that communicates with the junction.

  • Patent number: 5741023
    Abstract: The binding, which is suitable for touring skis as well as snowboards, is constructed in two parts and includes a base part which is shorter than the conventional touring binding and is mounted on a narrow snowboard by means of a fastening part without projecting over the lateral edges of the snowboard. As a result of the decreased length, the clamped in boot projects beyond the base part. A fastening part formed by a bearing part and a lengthening piece is arranged in a stationary manner with respect to the ski so that this base part can also be used as a touring binding. The lengthening piece is supported at the bearing part in a swivelable manner. This lengthening piece can be inserted into and secured within an insert enclosure constructed at the base part.

  • Patent number: 5738024
    Abstract: An apparatus and method for reducing NO.sub.x pollution in flue gas produced by a power plant uses heat exchanger elements having extended surfaces which contain a SCR catalyst, with the heat exchanger elements located in the flue gas stream. Coolant is passed through the heat exchanger elements to cool the catalyst, with a temperature control system used to maintain the catalyst at its optimum temperature such that the maximum conversion of NO.sub.x is achieved. Utilizing the present invention, temperature cycling of the catalyst is avoided, prolonging the life of the catalyst, while at the same time optimizing the efficiency of conversion regardless of variations in the flue gas flow or temperature.
