Patent CA-2337562-A1 (CA)
Inventor: YU YEUNG SIU
IPC: C12Q1/54
Filed: 2001-02-22
Abstract: A reagent is suitable for measuring the concentration of an analyte in a hemoglobin-containing biological fluid, such as whole blood. The reagent comprises a flavin-dependent enzyme that has specificity for the analyte, a flavin cofactor if, and only if, a flavin is not bound to the enzyme, a tetrazolium dye precursor, an electron transfer agent, and a nitrite salt. The reagent causes dye formation that is a measure of the analyte concentration. The nitrite salt suppresses interfering dye formation caused non-enzymatically by the hemoglobin.      Preferably, the reagent is used in a dry strip for measuring glucose in whole blood.

Patent CA-2347042-A1 (CA)
Title: Self-locking bayonet coupling mechanism
Inventor: HARMS KEVIN M
IPC: H01R13/625
Filed: 2000-08-25
Abstract: An automatically locking bayonet coupling mechanism includes, a linear guide structure (23, 23', 24) for preventing relative rotation between the coupler halves (20, 21), a sleeve (22) rotatably mounted on one of the coupler halves, a spring (27, 28) captured between the sleeve and the coupler half on which it is mounted to generate a torsional force between the sleeve and the coupler half, an L-shaped groove (25) in the other of the coupler halves, and a bayonet pin (26) extending from the sleeve and arranged to engage cam surfaces (42, 44) defined by edges of the groove. As the coupler halves are pushed together linearly, engagement between the bayonet pin (26) and a first (42) of the cam surfaces causes the sleeve to rotate against the force of the spring.  Subsequently, the bayonet pin is caused to engage a second (44) of the cam surfaces that forms a locking ramp. As the sleeve is caused to rotate into a locking position in response to the spring force, the angle of the locking ramp causes the spring force on the bayonet pin and locking ramp to also draw the coupler halves together, and to maintain the axial force that draws the coupler halves together after the bayonet pin comes to rest before the end of the locking ramp.

Patent CA-2349808-A1 (CA)
Title: Electrostatic fluid purifying device and method of purifying a fluid
Inventor: MONTEITH ROBERT A
IPC: C02F1/00
Filed: 2001-05-30
Abstract: A device and method for the treatment of fluids using electrostatic fields generated by a high voltage electric current, which reduces or eliminates calcification, scaling and microbiological contamination. A high voltage DC current is applied to a core electrode, generating an electrostatic field which traverses a dielectric sleeve surrounding the core electrode and charges the exterior surface of the dielectric sleeve, charging inorganic particles and, in the case of a biological contaminant such as bacteria, killing the organism. Fluid flowing through the device is agitated by a combination of spiral vane sections surrounding the dielectric sleeve and helical baffle sections lining the housing wall. Charged inorganic particles coalesce into spherical aggregates which resist adhesion to pipes and vessels and can be filtered by techniques such as reverse osmosis without deteriorating the filter membrane.  The device can thus be used to pre-treat water so as to enhance the performance and durability of purification systems such as reverse osmosis filtration systems.

Patent CA-2359094-A1 (CA)
Inventor: PINDER EDWARD
IPC: E04H1/12
Filed: 2001-10-15
Abstract: The present invention is a retrievable ice anchor for securing a portable shelter such as those used for ice fishing, to the ice surface of a body of water. The anchor is suspended vertically from an offset connector and lowered through a hole in the ice such as that used for fishing. Once lowered through the hole, the user pulls up on a connector. In a single connector embodiment, the connector is attached offset from the bar's center of gravity. When pulled up, one projection on the bar engages the underside of the ice and rotates to engage and anchor the bar. In a two connector embodiment, pulling on a second connector attached to the center of gravity of the anchor causes it to balance and thus engage the ice on either side of the hole. In either case the actuating connector is attached to a rope connected to the shelter so that the tension in the rope maintains tension in the actuating connector, keeping the anchor engaged in the hole. The anchor is readily retrieved by removing tension from the actuating connector causing the anchor to sink. The offset connector can be pulled upwardly, causing the anchor bar to depend vertically and be easily retrieved from the hole.

Title: Composition and method for acidizing wells and equipment without damaging precipitation
Inventor: BREZINSKI MICHAEL M
IPC: C09K8/74
Filed: 2001-11-01
Abstract: An acidizing composition and a method of acidizing a hydrocarbon bearing subterranean formation in the presence of ferric ions are provided. The acidizing composition includes an aqueous mineral acid solution, an electron donor agent and an electron transfer agent, the electron transfer agent being a source of molybdenum ions. When the aqueous mineral acid solution includes hydrochloric acid in an amount greater than approximately 17% by weight, the acidizing composition further includes a supplemental electron transfer agent, the supplemental electron transfer agent being a source of iodide ion or iodine. The electron donor agent and electron transfer agent function together to reduce ferric ion present in the mineral acid solution to ferrous ion which in turn prevents ferric hydroxide and/or free sulfur from precipitating out of the solution and reduces the formation of sludge in crude oil in the formation. The particular electron transfer agents used in connection with the invention function with virtually all known electron donor agents and are not as toxic as the copper based catalysts used heretofore.
