Patent CA-2324705-C (CA)
Inventor: BOSWELL BARRY
IPC: E21B29/00
Filed: 2000-10-27
Granted: 2007-01-02
Abstract: A rotating tool for milling or drilling in a well bore, having one or more rotating cutting structures, with each cutting structure rotating about its own axis, and with the cutting structures rotating about the axis of the tool. The rotational axis of the tool is offset from the axis of at least one cutting structure, with the axis of the tool passing through that cutting structure. This ensures that the cutting structure which spans the axis of the tool rotates independently of the tool, to prevent the existence of a zero velocity point on the cutting face of the tool.

Title: Methods of fabricating silicon carbide power devices by controlled annealing
Inventor: SUVOROV ALEXANDER V
IPC: H01L29/78
Filed: 1999-06-07
Granted: 2010-02-16
Abstract: Silicon carbide power devices are fabricated by masking the surface of a silicon carbide substrate to define an opening at the substrate, implanting p-type dopants into the silicon carbide substrate through the opening at implant energy and dosage that form a deep p-type implant, and implanting n-type dopants into the silicon carbide substrate through the opening at implant energy and dosage that form a shallow n-type implant relative to the deep p-type implant. The deep p-type implant and the shallow n-rype implant are annealed at less than 1650 °C, but preferably more than about 1500°. The annealing preferably takes place for between about five minutes and about thirty minutes. Ramp-up time from room temperature to the anneal temperature is also controlled to be less than about one hundred minutes but more than about thirty minutes. Ramp-down time after annealing is also controlled by decreasing the temperature from the annealing temperature to below about 1500 °C in less than about two minutes. By controlling the ramp-up time, the annealing time and/or temperature and/or the ramp-down time, high performance silicon carbide power devices may be fabricated.

Patent CA-2362693-C (CA)
Inventor: HOTTOVY JOHN D
IPC: C08F6/00
Filed: 2000-03-08
Granted: 2004-12-14
Abstract: A process and apparatus for passing a polymerization effluent, comprising solid polymer, unreacted monomer, diluent and minor amounts of contaminants, to a high pressure flash where most of the fluid components are flashed and wherein a slip stream comprising diluent and minor amounts of monomer is separated from the bulk of the flashed fluid components. The slip stream is subjected to olefin removal to give an essentially olefin-free stream for recycle to a catalyst mud preparation area. The bulk of the flashed fluid components are recycled directly back to the polymerization zone without expensive olefin removal, although treatment to remove other contaminants can optionally be performed. The polymer and entrained fluid is passed to a low pressure flash zone where the fluids are flashed off, compressed and joined with the flash from the high pressure flash tank.  Because the bulk of the fluids are removed in the high pressure flash, compression and cooling of product fluids prior to recycle is kept to a minimum.

Title: Hypochlorite free method for preparation of stable carboxylated carbohydrate products
Inventor: KOMEN JOSEPH LINCOLN
IPC: D21H11/20
Filed: 2002-04-26
Granted: 2004-11-23
Abstract: A method of making a carboxylated carbohydrate is disclosed, cellulose being a preferred carbohydrate material. Carboxylated cellulose fibers can be produced whose fiber strength and degree of polymerization is not significantly sacrificed. The method involves the use of a catalytic amount of a hindered cyclic oxammonium compounds as a primary oxidant and chlorine dioxide as a secondary oxidant in an aqueous environment. The oxammonium compounds may be formed in situ from their corresponding amine, hydroxylamine, or nitroxyl compounds. The oxidized cellulose may be stabilized against D.P. loss and color reversion by further treatment with an oxidant such as sodium chlorite or a chlorine dioxide/ hydrogen peroxide mixture. Alternatively it may be treated with a reducing agent such as sodium borohydride. In the case of cellulose the method results in a high percentage of carboxyl groups located at the fiber surface. The product is especially useful as a papermaking fiber where it contributes strength and has a higher attraction for cationic additives. The product is also useful as an additive to recycled fiber to increase strength. The method can be used to improve properties of either virgin or recycled fiber. It does not require high .alpha.-cellulose fiber but is suitable for regular market pulps.

Title: Vascular grafts and methods for bridging a vessel side branch
Inventor: DEHDASHTIAN MARK
IPC: A61F2/06
Filed: 2000-01-19
Granted: 2009-07-07
Abstract: A vascular graft (20) for a primary vessel (22) adapted to bridge a side branch (24). The graft is especially useful for providing a support tube for a primary graft in the primary vessel on one side of the side branch. The graft includes first and second tubular sections separated by a gap. A bridging member (54) connects the first (50) and second tubular sections (52) across the gap and may include a relatively rigid strut to prohibit relative axial movement of the two sections. There may be one, two or more bridging members to define one, two or more apertures through which blood can flow from within the graft through to the vessel side branch.  The graft may include a flexible, desirably fabric, body supported by a wireform stent that is either self- or balloon-expandable. The graft may be deployed within the abdominal aorta on both sides of the renal arteries and have two apertures for blood to flow from the aorta to the renals. The infra-renal section provides a uniform uniform tubular anchoring surface for a trunk portion of a bifurcated graft used to repair an abdominal aneurysm extending to the iliac arteries.

Title: Method of shifting an image or paper to reduce show through in duplex printing
Inventor: KERXHALLI DAVID M
IPC: B41J3/60
Filed: 2002-08-20
Granted: 2009-08-11
Abstract: The relationship between first and second side images is evaluated to determine how the position of the paper and/or the size and arrangement of an image can be manipulated to compensate for paper shrinkage caused by fusing. Show through is reduced by performing setup to adjust a pixel clock frequency and/or a photoreceptor speed, determining a residual magnification error, determining margin shifts to compensate for the residual magnification error, and applying the margin shifts. Paper shrink effects on registration can be compensated for using determinations made during a typical printer setup. Show through errors can be reduced without using a paper conditioner to pre-shrink or re-wet the paper. In simplex and duplex printing, the show through errors worsen as the image moves away from the registration edge. Using information obtained during setup, a margin shift is determined that results in a significant reduction in the maximum show through for each image.

Abstract: A system for detecting ground faults in a compensated electric power distribution network includes the determination of zero sequence voltage (V0) and zero sequence current (I0) on a power line and calculating the zero sequence conductance (G0) therefrom. The oepration of the conductance calculation circuit occurs only under selected power line conditions involving minimum values of zero sequence voltage, zero sequence current and positive sequence voltage, to ensure the accuracy of a fault direction determination. The conductance values are processed on an adaptive basis in which the difference between the most recent conductance value and a conductance value from a selected previous point in time is determined and then compared against threshold values to make forward and reverse fault declarations.
