    摘要: An improved dehydrogenation catalyst bed system for olefin production utilizing classical processing techniques is disclosed. The catalyst bed system comprises a dehydrogenation catalyst comprising an active component selected from an oxide of a metal of Group 4 or Group 5 or Group 6 and combinations thereof and a support selected from aluminum oxide, aluminas, alumina monohydrate, alumina trihydrate, alumina-silica, transition aluminas, alpha-alumina, silica, silicate, aluminates, calcined hydrotalcites, zeolites and combinations thereof mixed with a first inert material selected from any material that is catalytically inactive when subjected to reaction conditions that can effect dehydrogenation of olefins and that has a high density and high heat capacity and that is not capable of producing heat during any stage of the dehydrogenation process, and the dehydrogenation catalyst plus the first inert material then being physically mixed with a secondary component comprising a heat-generating inert material and a carrier capable of supporting the heat-generating inert material, wherein the secondary component is catalytically inert with respect to dehydrogenation reactions or to cracking or to coking and generates heat after being exposed to reducing and/or to oxidizing reaction conditions.

    摘要: Systems and methods access non-compatible content repositories that are not natively accessible to a content management system. A metadata registry maintains metadata about content stored in both compatible and non-compatible repositories. For content in a non-compatible repository, the metadata indicates a repository interface capable of accessing the non-compatible repository. The content manager communicates with the repository interfaces to access the content in non-compatible repositories. The content manager may receive a request for content in a non-compatible repository, refer to the metadata registry to select a repository interface to employ, transmit a request for the requested content to the selected repository interface, and receive the requested content from the repository interface. A repository interface registry maintains information about available repository interfaces. Entries may be added to either the metadata registry and the repository interface registry, thus allowing the systems and methods to be extended to be able to access additional non-compatible repositories.

    摘要: A bearing assembly includes a roller bearing having a bore, and a pin positioned within the bore. The pin has a composite outer profile defined by a first substantially circular segment with a first axis of rotation, and a second substantially circular segment with a second axis of rotation of a different radius. The second axis of rotation is offset from the first axis of rotation.
