Title: Oil well treatment
Inventor: BOURNE HUGH MALCOLM
IPC: E21B37/06
Filed: 1995-05-30
Abstract: Corrosion, scale-formation, or other deleterious processes are inhibited in an oil well by providing within the oil well (10) elements comprising an insoluble porous inorganic material in which is absorbed a well treatment chemical. The material may be in the form of particles or beads, for example porous ceramic spheres impregnated with an inhibitor material. Such particles may be injected as proppant particles into the formation through which the well extends, during a fracturing treatment. Alternatively such particles may be packed as a filter bed (26) in a filter (20) comprising two spaced tubular screens (24) between which the filter bed (26) is located. The inhibitor material gradually dissolves in the well fluids during operation, and may for example inhibit corrosion and/or scale-formation.

Title: Sticker placing mechanism for use with lumber stacker
Inventor: BEST THOMAS S
IPC: B65G57/00
Filed: 1997-09-15
Abstract: A sticker placing mechanism for use with known lumber stackers and perpendicularly associated sticker distribution provides sticker pans carried by arms of a lumber stacking fork to move downwardly to pick up plural stickers from the sticker conveyor and move the stickers upwardly beneath an accumulated layer of lumber. The layer of lumber and perpendicularly orientated stickers is moved upwardly and forwardly by the stacking fork on an adjacent stacked lumber package. The stacking fork and associated sticker pans then retract into the stacker while stripping mechanism prevents rearward motion of the stickers and lumber layer to leave the stickers and lumber layer as the top course of the stacked lumber package. In a first species, the sticker pans are immovably carried by the stacking fork arms and moved downwardly by those arms. In a second species, the sticker pans are pivotally mounted on the stacking fork arms and mechanically pivoted for sticker pick up. The sticker placing mechanism is adaptable to retrofitting on existing lumber stackers.

Patent CA-2227595-A1 (CA)
Inventor: BERGEN JAMES R
IPC: G06T11/20
Filed: 1996-08-05
Abstract: A method and apparatus for synthesizing texture images that match the texture appearance of a given digitized sample of an image. This synthesis is completely automatic and requires only the "target" texture image as an input. It allows generation of as much texture as desired so that any object or surface can be covered with the synthesized texture. The apparatus generates texture parameters for the target texture sample image that reflect the texture in that image. These texture parameters are used to modify the noise image such that the modified noise image attains the texture of the target texture image. To further improve the texture of the modified noise image, an image pyramid is constructed for both the modified noise image and the target texture sample image. The apparatus then iteratively updates the modified noise image on a coarse-to-fine basis using the subbands of the image pyramids. The output image is an updated modified noise image that has attained the texture of the target texture sample image.

Patent CA-2231749-A1 (CA)
Inventor: MANDAI SHIGEMI
IPC: F02C3/30
Filed: 1998-03-11
Abstract: A low-NOx combustor and gas turbine apparatus which, while using a fuel containing nitrogen components, suppresses the rate at which these components are converted to NOx by mixing the air which supports combustion with a gas having an oxygen  concentration  which  is  lower  than  that  of  the atmosphere so that the oxygen level in the resulting air mixture is maintained between 13 and 17%, preferably between 14 and 16%.   In a gas turbine apparatus,  the aforesaid oxygen-poor air mixture may be generated using the combustion exhaust gas from the turbine by installing a cooling device to reduce the temperature of the combustion exhaust gas from the turbine and supplying the cooled gas to the inlet of an air compressor, or by installing an exhaust gases compressor on the exhaust gas duct of the turbine and supplying the pressurized gas to the inlet of the combustor.

Title: "the deboner" a device to hold a headless, previously eviscerated fish in position while its back and rib bones are safely cut free and removed
Inventor: DOW JAMES
IPC: A22C25/00
Filed: 1998-06-12
Abstract: A portable, lightweight, easily cleaned fish holder for conveniently positioning a fish whiles safely removing the back and rib bones in preparation for specialty curing, cooking or smoking processes. This device importantly does not puncture the skin when the fish is held. The device's nonskid base sits on a horizontal surface and the base's "M" shaped top surface forms knife and sharpener storage pockets and the tapered "V" into which the fish's back is placed. Near the base's tail end an arch type frame, sliding arm and cross bar swivel/slide assembly straddle the base's "V" and fish's tail portion. When moved in line with fish's back bone and pressed downward the sliding arm and cross bar spread the rib section open and hold the fish tight to the base and ready to be boned out. All cutting is done below the cross bar leaving the hand that holds the sliding cross bar arm in a safe position so as not to be jabbed or sliced.
Patent CA-2240868-A1 (CA)
Inventor: CROWLEY CHRISTOPHER W
IPC: G01N24/08
Filed: 1998-07-15
Abstract: A method for creating an image of in situ biological tissue uses an inhomogeneous field MRI device to pulse the tissue with sequential epochs of excitation pulses. Each epoch of excitation pulses includes, in order, an initial tilting pulse, an x-y encode and a train of refocussing pulses. Specifically, each x-y encode has a K-space identifier of the form i(1..m) + j(1..n), and the tilting pulses change sign according to whether the K-space identifier (i+j) is odd or even. For an image having mxn pixels, nxn epochs are used to generate nxn measurements of imageable spin echo signals. These mxn measurements are then collated to create the image.

On perce enfin l'élément selon trois diamètres différents: un diamètre pour former le siège de bille de soupape, et deux diamètres pour les alésages accueillant le ressort de bille de soupape. Après insertion de la bille (110) et du ressort (112), une extrémité de l'élément est rabattue sur une extrémité du ressort (112) de façon à immobiliser le ressort.
Patent CA-2248280-A1 (CA)
Inventor: GLASSFORD CRAIG
IPC: B01D61/02
Filed: 1998-04-03
Abstract: There is disclosed a system for separating oil and other immiscible contaminants from a liquid body containing the contaminants such as a water body. The system includes the use of a plurality of microporous hollow fibers which may be arranged in any number of arrangements such as bundles, intersecting arrangements, divergent patterns or in a mat-like arrangement or a combination of the foregoing. The hollow fibers are in communications with a source of pressure in order to force the contaminant via the pores into the fibers for subsequent storage in a suitable container. By incorporating acceptable means of density control a substantial amount of the hollow fiber surface area may be exposed to the contaminant thus increasing the extraction efficiency of the contaminant from the water body. The unit optionally may be self-contained. Thissystem provides a substantial advantage over existing arrangements in that extraction efficiency is greatly enhanced in any number of environments.  The system and methods are also useful in recovering crude oils, metals or other dissolved components, etc., from the aqueous phase.

Title: Improved tissue destruction in cryosurgery by use of thermal hysteresis proteins
Inventor: KOUSHAFAR AMIR-HOMAYOON
IPC: A61P27/00
Filed: 1997-03-26
Abstract: Cell and tissue destruction by cryoablation is enhanced by the perfusion of the cells with thermal hysteresis proteins prior to the cryogenic freezing.  The effect of the proteins is to promote the growth of spicular ice crystals in the intracellular fluid which destroy the cell by piercing the cell membrane. This decreases the incidence of cell preservation by freezing, thereby permitting a more uniform and controllable destruction of undesirable tissue by the cryoablation technique.
