  • Patent number: 7014881
    Abstract: An inert anode 50, for use in an electrolytic cell 12 for producing metals such as aluminum, is made by providing chemical source materials 100 such as at least two of metal salts, metal particles, or metal oxides and dissolving them to form a solution or a slurry 110, followed by adding a base 120 and adjusting the pH so that a gel 130 is formed which is dried and calcined 150, 160, 190 to provide a blend of metal oxide powder 200 which can be pressed and sintered 220 to form an inert anode 50.

  • Patent number: 5955048
    Abstract: There is provided a flash activated hydrotalcite which, when extruded to sizes of about 1/16 inch or more, has a crush load strength of at least about 7 pounds. The process for making this extrudate includes: (a) providing a hydrotalcite compound; (b) heating said compound for less than two seconds to one or more temperatures above about 482.degree. C. (900.degree. F.); (c) cooling said heated compound; (d) collecting said cooled compound; (e) forming said compound into an extrudate; and (f) reactivating said extrudate by heating to one or more temperatures above about 400.degree. C. (752.degree. F.) for about 20 minutes or more. Further strength improvements are achieved by exposing these extrudates to steam for at least about 8 hours prior to step (f).

  • Patent number: 5938927
    Abstract: Oil and oil additives separated from a contaminated solid particulate filter medium, preferably diatomaceous earth particles. Portions of a mixture of oil, oil additives and the filter medium are compressed into pellets that are extracted with liquid or supercritical CO.sub.2 to form a liquid solution. The solution is separated from the pellets and then heated to 20.degree.-60.degree. C. at a superatmospheric pressure to drive off CO.sub.2 gas, which is preferably recycled by compression into liquid or supercritical CO.sub.2.

  • Patent number: 5884298
    Abstract: A method accesses and updates information from a library of optical discs and includes a step of cataloging optical discs. The cataloging step includes the generation of a unique value for each of the cataloged discs. The unique value is produced by iteratively reading data from each disc and iteratively combining the data. The cataloging step includes the generation of catalog data streams. The catalog data streams include fixed length data representing file and directory attributes and variable length data representing file names and directory names. The method includes the further step of producing limited depth catalogs representing file and directory information on the optical discs. The limited depth catalogs have a fixed number of subdirectory levels and file types. The fixed number is selected by a user, and the file types are selected by a user. The method includes the further step of caching optical disc data to a hard disc.
