  • Gas turbine overspeed protection system
    Patent number: 8246294
    Abstract: An overspeed protection system for a gas turbine engine comprises: a plurality of engine speed sensors that generate engine speed signals; and a plurality of engine overspeed detection channels, each channel comprising an overspeed detector that receives and generates an overspeed signal when it detects the engine speed signal exceeding a selected value of overspeed.

  • Nickel-substituted and mixed nickel-and cobalt-substituted chromium oxide compositions, their preparation, and their use as catalysts and catalysts precursors
    Publication number: 20050227865
    Abstract: A crystalline alpha-chromium oxide where from about 0.05 atom % to about 2 atom % of the chromium atoms in the alpha-chromium oxide lattice are substituted by nickel atoms, and optionally, additional chromium atoms in the alpha-chromium oxide lattice are substituted by trivalent cobalt atoms (provided that the total amount of the nickel atoms and the trivalent cobalt atoms in the alpha-chromium oxide lattice is no more than 6 atom %) is disclosed. Also disclosed is a chromium-containing catalyst composition comprising as a chromium-containing component the crystalline substituted alpha-chromium oxide; and a method for preparing a composition comprising the crystalline substituted alpha-chromium oxide.
