  • Publication number: 20120028863
    Abstract: The present invention is generally directed to methods of making application-specific finished lubricant compositions comprising bio-derived diester species. In some embodiments, bio-derived fatty acid moieties are reacted with Fischer-Tropsch/gas-to-liquids reaction products and/or by-products (e.g., gas-to-liquids-produced ?-olefins) to yield bio-derived diester species that can then be selectively blended with base oil and one or more additive species to yield an application-specific finished lubricant product having a biomass-derived component.

  • Patent number: 6928432
    Abstract: A new and useful updating tool is provided for indexing electronic text in a highly integrated electronic text indexing and search system. The integrated system encompasses a concept model, a query model, an enhanced markup tool, a user interface, and a search engine. A domain expert utilizes the integrated system to efficiently and effectively indexing electronic text for precise and fast retrieval by a search engine. The updating tool aids the indexing process as a consequence of changes in the query model, to an indexed document, or both. The updating tool comprises a document change tool and a query model change tool as well as an enhanced markup tool and an enhanced query model tool. The updating tool guides the domain expert by suggesting which indices need to be updated and flags index entries that need to be removed.

  • Patent number: 6535873
    Abstract: System and method for integrating electronic text indexing and search. A concept model defines a set of concept-value pairs. A set of queries is constructed in the query model in terms of a subset of the concept-value pairs, which is used to create allowable concept-values in an inventive markup tool for assignment, via markup tags, to sentences of a piece of electronic text. Concepts are automatically updated as the query model is updated to keep the concept-values used in the markup tool consistent with the concept-values used in the query model. The queries and the assigned markup tags integrate concept-values from the concept model. The integration of the concept model with the markup tool and the query model tool makes indexing electronic textbooks much quicker with less effort.
