Patent CA-2480448-A1 (CA)
Title: Pressure relief valve with improved repairability
Inventor: SCHIMNOWSKI KENNETH ROGER
IPC: F16K17/04
Filed: 2003-03-26
Abstract: A repairable pressure relief valve (2) having a valve body that forms an internal fluted surface (9) provides improved field repairability. The internal, fluted surface is adapted to mate with a removal tool (31). A valve assembly (6) is slidably mounted in the valve housing and slides under excess pressure to vent vapor from a vessel (40) , such as a tank. The valve body has a first seating surface (22) for mating with a second seating surface (24) on the valve assembly when the valve plug (14) is in the closed position. The relief valve has a seal (28) for sealing an interface between the valve plug and the housing and a removable cap (8) mounted proximate to the valve plug for mechanically supporting the seal. The cap can be removed and the seal can be replaced without extensive disassembly of the valve, thereby eliminating the requirement of re-calibration after a repair has been made.

Title: Method of encapsulating hydrophobic organic molecules in polyurea capsules
Inventor: CROLL LISA M
IPC: A61K9/50
Filed: 2003-06-02
Abstract: It is known to encapsulate various materials in polyurea microcapsules, but obtaining satisfactory microcapsules incorporating alcoholic materials has proven difficult. A process has now been found where polyurea microcapsules are formed by interfacial polymerization between an aqueous phase and a water-immiscible phase, and properties, particularly the solubility parameters, of the water~ immiscible phase are closely matched to corresponding properties of the polyurea. Microcapsules prepared by this process have improved stability, mechanical strength and controlled release properties.
Patent CA-2490301-A1 (CA)
Title: Quantitation by serial combinatorial dilution
Inventor: EVERS STEFAN
IPC: C12Q1/68
Filed: 2004-12-15
Abstract: The invention provides a method for the quantification of a biomolecule in a complex mixture of biomolecules which comprises a fractionation of the mixture of biomolecules providing at least two fractions with at least one distinct component each. These fractions are then subjected to serial combinatorial dilution.  Subsequently, the biomolecule is detected and identified in the fractions by a method providing a sensitivity threshold and identify information. The quantity of the biomolecule is determined by summarizing the number of identifications of the biomolecule in each fraction on each dilution level in consideration of the respective dilution factor. For purpose of normalization this sum may be divided by the total number of identifications of all biomolecules in all fractions on all dilution levels.

Title: Method and apparatus for varying the density of drilling fluids in deep water oil drilling applications
Inventor: DE BOER LUC
IPC: E21B21/10
Filed: 2003-11-03
Abstract: A method and apparatus for controlling drilling mud density at a location either at the seabed (20) (or just above the seabed (20)) or alternatively below the seabed of wells (40) in deep water and ultra deep water applicatio ns are disclosed. The present invention combines abase fluid of lesser density than the mud required at the wellhead (300) to produce a diluted mud in the riser (80). By combining the appropriate quantities of drilling mud with bas e fluid, a riser mud density at or near the density of seawater may be achieve d. The present invention also includes a wellhead injection device (32) for attachment to the wellhead (300) and for injecting the base fluid into the rising drilling mud at a location below the seabed (20). The riser charging lines (100) are used to carry the low density base fluid to the injection device (32) for injection into the drilling mud below the seabed (20). The cuttings are brought to the surface with the diluted mud and separated in th e usual manner. The diluted mud is then passed through a centrifuge system to separate the heavier drilling mud from the lighter base fluid.

Patent CA-2513690-A1 (CA)
Title: Solid phase sequencing
Inventor: FULLER CARL
IPC: C12Q1/68
Filed: 2004-02-05
Abstract: The present invention describes methods of sequencing a nucleic acid in a sample, based on the use of terminal-phosphate-labeled nucleotides as substrates for nucleic acid polymerases. The methods provided by this invention utilize a nucleoside polyphosphate, dideoxynucleoside polyphosphate, or deoxynucleoside polyphosphate analogue which has a colorimetric dye, chemiluminescent, or fluorescent moiety, a mass tag or an electrochemical tag attached to the terminal-phosphate. When a nucleic acid polymerase uses this analogue as a substrate, an enzyme-activatable label would be present on the inorganic polyphosphate by-product of phosphoryl transfer. Cleavage of the polyphosphate product of phosphoryl transfer viaphosphatase leads to a detectable change in the label attached thereon. In some instances the labeled polyphosphate may be detected directly via the label and provide information on the nucleic acid. When the polymerase assay is performed in the presence of a phosphatase, there is provided a convenient method for real-time monitoring of DNA or RNA synthesis and characterization of a target nucleic acid.
