  • Patent number: 6711797
    Abstract: A tooling fixture includes a plurality of cylinders in a module fitted with pistons in which a portion thereof extends from the surface of the module. The cylinders are connected with a fluid source by a control valve assembly. The control valve assembly controls the amount of fluid to enter the cylinders in order to raise the pistons until a portion thereof are in contact with and support a workpiece. Once all of the pistons are in contact with and are fully supporting the workpiece, the fluid pressure is stabilized, maintaining the pistons at their set heights. Once the pistons are desired to be lowered, the valve assembly opens and the fluid can freely exit the cylinders and retract the pistons back into the module.

  • Patent number: 6670185
    Abstract: The present invention is directed generally to activating gene expression or causing over-expression of a gene by recombination methods in situ. The invention also is directed generally to methods for expressing an endogenous gene in a cell at levels higher than those normally found in the cell. In one embodiment of the invention, expression of an endogenous gene is activated or increased following integration into the cell, by non-homologous or illegitimate recombination, of a regulatory sequence that activates expression of the gene. The invention also provides methods for the identification, activation, isolation, and/or expression of genes undiscoverable by current methods since no target sequence is necessary for integration. The invention also provides methods for isolation of nucleic acid molecules (particularly cDNA molecules) encoding a variety of proteins.

  • Patent number: 6653119
    Abstract: White rot fungi capable of decomposing dioxin were screened from rotten wood to isolate the MZ-340 strain. This MZ-340 could be cultured in the Kirk liquid medium (HCLN) or PDB medium. New systems that can be used to decompose dioxins in incineration ash were constructed using this MZ-340 strain. The present invention can decompose dioxins in incineration ash effectively and efficiently in both solid phase systems and liquid phase systems. Thus, the present invention enables the prevention of environmental pollution by dioxins generated during incineration and also the clean up of dioxin pollutants.

    Abstract: The present invention is directed generally to activating gene expression or causing over-expression of a gene by recombination methods in situ. The invention also is directed generally to methods for expressing an endogenous gene in a cell at levels higher than those normally found in the cell. In one embodiment of the invention, expression of an endogenous gene is activated or increased following integration into the cell, by non-homologous or illegitimate recombination, of a regulatory sequence that activates expression of the gene. In another embodiment, the expression of the endogenous gene may be further increased by co-integration of one or more amplifiable markers, and selecting for increased copies of the one or more amplifiable markers located on the integrated vector. In another embodiment, the invention is directed to activation of endogenous genes by non-targeted integration of specialized activation vectors, which are provided by the invention, into the genome of a host cell.
