Patent CA-2170765-A1 (CA)
Inventor: KAEMPEN CHARLES E
IPC: B65D90/501
Filed: 1995-07-05
Abstract: A   composite   double-wall   underground   tank comprises an internal rotatable metal mandrel tank frame   structure   surmounted  by  two   individual concentric corrugated cylindrical nonmetallic pressure vessels having hemispherical ends.   The metal tank frame structure provides the buckling resistance and compression strength to resist soil loads when the tank is buried.   The pressure vessels are made of identical materials and include an internal primary container enclosed by an external secondary container of equal tensile strength and corrosion-resistance.          The  composite  double-wall  underground  tank  is  a substantial improvement over conventional steel and fiberglass tanks, and provides a more reliable method of  protecting  the  environment  by  preventing  the release of contaminating hazardous liquids stored in the tank.  Each of the two pressure vessels is made from a multiple ply composite laminate having a unique arrangement   of    fabrics   containing    filament reinforcements  impregnated  with  a  thermosetting polymeric  matrix.    The  hemispherical  ends  have sealable axle access openings.  The top tank fitting outlets  include  non-corrugated  portions  of  the cylindrical laminate structures bonded together and sandwiched  between  bolted  metal  plates  that  are structurally connected to the tank frame and sealed with an overlapping laminate structure.

Patent CA-2196496-A1 (CA)
Inventor: MICHNICK STEPHEN
IPC: A61K48/00
Filed: 1997-01-31
Abstract: We describe a strategy for designing protein-fragment complementation assays to detect protein-protein interactions in vivo. The design and implementation of this strategy is illustrated with the enzyme murine dihydrofolate reductase (DHFR). Fusion peptides consisting of N- and C-terminal fragments of murine DHFR fused to GCN4 leucine zipper sequences were coexpressed in Escherichia coli grown in minimal medium, where the endogenous DHFR activity was inhibited with trimethoprim. Coexpression of the complementary fusion products restored colony formation. Survival only occurred when both DHFR fragments were present and contained leucine-zipper forming sequences, demonstrating that reconstitution of enzyme activity requires assistance of leucine zipper formation. DHFR fragment-interface point mutants of increasing severity (Ile to Val, Ala and Gly) resulted in a sequential increase in E. coli doubling timesillustrating the successful DHFR fragment reassembly rather than non-specific interactions between fragments. This in vivo assay could be used to study equilibrium and kinetic aspects of protein-protein interactions and forscreening cDNA libraries for binding of a target protein with unknown proteins. Further, the selection and design criteria applied here to DHFR could be used to develop a strategy using any enzyme that would be appropriate for a clonal selection or direct detection of enzyme activity.
