Patent CA-2350367-A1 (CA)
Title: High speed evaporator defrost system
Inventor: DUBE SERGE
IPC: F25B5/02
Filed: 2001-06-12
Abstract: A high-speed evaporator defrost system is described. It comprises a defrost conduit circuit having valves for directing hot high pressure refrigerant gas from a discharge line of a compressor and through a refrigeration coil of an evaporator of a refrigeration system during a defrost cycle thereof, and back to a suction header of the compressor through a reservoir of the refrigeration system to remove any liquid refrigerant contained in the refrigerant gas prior to returning to the suction header. The reservoir has an internal pressure which is generally at the same pressure as that of a suction header of the compressor thereby creating a pressure differential across the refrigeration coil sufficient to accelerate the hot high pressure refrigerant gas in the discharge line through the refrigeration coil of the evaporator to quickly defrost the refrigeration coil. The reservoir is repressurized after the defrost cycle for using the reservoir in a refrigeration cycle.

Abstract: An expandable endovascular medical tubular stent is a supporting device intended to maintain the walls of anatomical body channels or vessels, the stent being expandable within the vessel by an angioplasty balloon associate d with a catheter thereby dilating and expanding the lumen of a vessel. The stent comprises an arrangement of a plurality of radially expandable, serpentine members arranged in interconnected rings. Upon inflation of the balloon, the stent expands in both radial and longitudinal directions in relation to the amount of radially- outwardly directed force by the balloon.  The stent is designed such that during expansion, local plastic deformation occurs only at the points of inflection distributed throughout the rings. Expansion is limited in proportion to the amount of expansion to ensure the resulting expanded stent is within material fracture limits and that adequat e wall supporting structure is provided thereby.

Title: Combinations of imidazolines and wetting agents as environmentally acceptable corrosion inhibitors
Inventor: BRAGA THOMAS G
IPC: C23F11/10
Filed: 2000-02-16
Abstract: A method and corrosion inhibitor for inhibiting corrosion of metal equipment in an aqueous medium comprising components selected from the group consisting of Skeletonema costatum, fish, other algae, and a combination thereof. The method comprises incorporating into the medium a corrosion inhibiting amount of a water soluble corrosion inhibitor comprising an N-ethoxy, 2-substituted imidazoline. The N-ethoxy substituent comprises a quantity of ethylene oxide effective to render the imidazoline water soluble. The corrosion inhibitor is rendered more environmentally compatible by shortening the number of carbon atoms in the fatty acid chain at the 2-position of the imidazoline. The fatty acid chain consists essentially about 18 carbon atoms or less, preferably about 10 carbon atoms or less, most preferably from about 6 to about 8 carbon atoms. As the number of carbon atoms in the fatty acid chain is reduced, the efficacy of the corrosion inhibitor is increased by combination with a wetting agent, preferably an ethoxylated alcohol having from about 8 to about 10 carbon atoms.

Abstract: A queuing architecture and method for scheduling disk drive access requests in a video server. The queuing architecture employs at least two access request  queues (221; 222, 223) for each disk drive (120) within a disk drive array. A first queue (221) is for disk access requests by steady-state users currentl y viewing a program. A second queue, which may include multiple queues (222, 223), is for all other types of access requests including requests by users who wish to begin viewing a program, disk maintenance, meta data synchronizi ng and the like. A queue selector (205) gives highest priority to requests in t he first queue to maintain time deadlines for steady state disk access requests , which are serviced in order of ascending deadlines. Requests from the second  queue are serviced only if all of the steady-state requests in the first que ue will meet their time deadlines in the worst case.

Patent CA-2372568-A1 (CA)
Inventor: CADD JIMMY W
IPC: H04L12/56
Filed: 2001-03-30
Abstract: A medium access protocol which adjusts number of contention slots in a variable length frame and superimposes a variable window structure over the frame structure. The number of contention slots (24) in a frame (28, 30) is changed on a frame by frame basis by determining if a collision occurred in any contention slot (44). If not the contention slot is removed (48) and if so, the number of slots is increased (52). In high traffic situations, if the average load is greater than a threshold (107, 120) the number of frames in a window is increased (130). If the load drops below the threshold (120), the number of frames per window is decreased (124).

Abstract: The invention relates to new sulfonamide derivatives of aryl or heterocyclic compounds and to their pharmaceutically acceptable salts. The new derivatives of the invention can be obtained with chemical synthetic processes known in the art.  For example, they can be prepared by mono- or poly-condensation of a suitably substituted sulfonamide compound. The sulfonamide compounds of the invention are active, in particular, as inhibitors of carbonic anhydrase isoenzymes and therefore they can be useful in therapy, in particular in the ophthalmic field. In fact these compounds are able to decrease the intraocular pressure in glaucoma and to improve the protection of the retina. The new sulfonamide derivatives can be administered to humans in the form of different pharmaceutical preparations, in particular eye drops.

Title: System for electrochemical quantitative analysis of analytes within a solid phase
Inventor: WANG KAI HUA
IPC: G01N33/558
Filed: 2000-05-05
Abstract: The invention is directed to a system, method, and test strip for solid phase, electrochemical, quantitative analysis of analytes contained in biological fluid samples. A test sample can be applied to a sample collection pad. The test sample solution and a test kit reagent are then contacted and caused to migrate along a fluid pathway. A test kit reagent (e.g. labeled substance) and the analyte of interest (e.g. proteins, hormones or enzymes, polysaccharides, antibodies, nucleic acids, drugs, toxins, viruses, portions of a cell wall), either interact with one another to form a complex, or, alternatively, compete with one another for interaction with another test kit reagent, resulting in concentration of an indicator substance within a delimited area of the solid phase. The delimited area is subjected to electrochemical analysis and the results determined by monitoring an electrochemical transition in the form of an indicator, or derivative of the indicator by potentiostatic or potentiometric quantitative analysis (e.g. anodic stripping voltammetry). The electrochemical transition of the indicator has a characteristic electrical fingerprint that can be correlated with the concentration of the analyte in the sample.
