  • Patent number: 8563292
    Abstract: Crude solid vanillin-containing material is precipitated from a solution obtained by biotransformation, and purified by a process comprising contacting it with a purification fluid selected from (a) a liquefied gas whose pressure exceeds its critical pressure and whose temperature is below its critical temperature; (b) a supercritical fluid; (c) a gas. The fluid is preferably liquid carbon dioxide. The temperature is maintained below 25° . The product may be further purified by treatment with CO2 in a fluid bed drier. The crude material is preferably one precipitated from a solution resulting from biotransformation of ferulic acid. A new strain of Amycolatopsis capable of generating high concentrations of vanillin with minimal odoriferous by-products (e.g. guaiacol) is also disclosed.
    Type: Grant

  • Patent number: 6595879
    Abstract: A transportable basketball rim and net with optional back-board blocking training tool assembly is provided for use on a pre-existing metal goal. The base rim with net is installed over and removed from a pre-existing metal goal without the use of a ladder. The net and training tool can be removably attached to the plastic rim before the assembly is installed on the hoop. The base includes an optional insert to allow installation of the rim over a six or five inch pre-existing mount.
