  • Patent number: 7475173
    Abstract: An integrated data storage control system provides, in a single integrated circuit, RDC, servo logic, ATA interface, microprocessor, and other formerly discrete components in one highly integrated system design. The integrated circuit is rendered using a single integrated circuit technology type (e.g., digital CMOS) for all components. Analog and digital circuits are combined in such a way as to eliminate or reduce noise or interference in digital circuits from analog circuit components. Individual elements may have their outputs and inputs MUXed together such that individual elements can be selectively switched (during testing modes) such that the integrated circuit emulates or behaves in the same or similar manner as one of the prior art components. The present invention may be applied to magnetic hard disk drives (HDDs) or other types of storage devices such as floppy disk controllers, optical disk drives (e.g., CD-ROMs and the like), tape drives, and other data storage devices.

  • Publication number: 20060029705
    Abstract: An aqueous emulsion comprises a mixture of water, an aromatic or volatile essential oil flavorant, in particular a citrus oil, and an amount of hemicellulose or hemicellulose hydrolyzate to produce a stable emulsion. The aqueous emulsion may be spray-dried to form an oxygen stable composition. The aqueous emulsion and spray-dried composition may be used to produce products such as citrus oil beverages.

  • Publication number: 20060029712
    Abstract: Holocellulose is used in combination with fruit or vegetable juice as a substitute for fruit or vegetable pulp in food pulps and purees requiring a food pulp ingredient. For example a corn hull holocellulose the mimetic can replace ingredients such as tomato paste and apple sauce, both of which are costly additives for sauces and bakery products. Corn hull holocellulose, combined with fruit or vegetable juice, provides the expected texture ordinarily provided by the food pulp. Moreover, expected tastes and aromas of the products may be obtained using corn hull holocellulose when combined with juices such as tomato and apple juice.

  • Publication number: 20060029702
    Abstract: Various methods of obtaining hemicellulose from plant sources are provided. In one embodiment, hemicellulose is obtained from plant hulls by first jet cooking a plant hull slurry to remove starch from the plant hulls, and subsequently jet cooking the destarched plant hull slurry to extract a solubilzed hemicellulose. In an alternative embodiment, hemicellulose may be obtained by forming a plant hull slurry, adding sufficient lime to enable starch gelatinization and separation of hemicellulose in a single jet cooking step, jet cooking the slurry, and separating solubilized hemicellulose from insolubles. Surprisingly, the yield of hemicellulose is high, and the starch from the plant hulls will gelatinize but will not become hydrolyzed, such that the formation of reducing sugars is substantially avoided.

  • Publication number: 20050282777
    Abstract: Disclosed are saccharide-derivatized oligosaccharides. The derivatized oligosaccharides preferably are prepared by extruding a malto-oligosaccharide mixture with a saccharide or mixture of saccharides having a DP ranging from 1 to 4. The products are low in digestibility, and thus in various embodiments are suitable for use as bulking agents, for controlled energy release products, and for other purposes.

  • Publication number: 20050260316
    Abstract: Disclosed is a cold-water soluble starch and a process for preparing same. Generally, the process comprises providing a hydroxyalkyl starch and applying a shearing force to the starch in an extruder in the presence of moisture, the force and the moisture each being sufficient to gelatinize at least substantially all of the granules of the starch to thereby form a sheared starch. The starch is heated to its gelatinization temperature after the starch has passed partially through the barrel of the extruder, with the moisture being maintained at a level sufficiently high to allow gelatinization but sufficiency low to protect the starch from becoming too sticky to extrude. The extruded starch product thus formed may be used in connection with a number of film-forming, coating, and other applications.

  • Publication number: 20050194566
    Abstract: Disclosed are dust suppressant and aggregate stabilization compositions. In accordance with the subject disclosure, hemicellulose is used as a dust suppressant and/or as a stabilization composition for aggregates such as a road bed or soil field. Other ingredients may be used in a composition in conjunction with hemicellulose. For instance, a lignin compound may be used to enhance dust suppression and/or aggregate stabilization. A surfactant may be used to decrease the viscosity of the composition. A crosslinking agent may be used to enhance the water resistance of the composition. A chloride salt may be added to increase the hygroscopicity of the composition.
