Patent CA-2277378-A1 (CA)
Title: Steam-assisted gravity drainage heavy oil recovery process
Inventor: CYR TED
IPC: E21B43/24
Filed: 1999-07-08
Abstract: A pair of vertically spaced, parallel, co-extensive, horizontal injection and production wells and a laterally spaced, horizontal offset well are provided in a subterranean reservoir containing heavy oil. Fluid communication is established across the span of formation extending between the pair of wells. Steam-assisted gravity drainage ("SAGD") is then practised by injecting steam through the injection well and producing heated oil and steam condensate through the production well, which is operated under steam trap control. Cyclic steam stimulation is practised at the offset well. The steam chamber developed at the offset well tends to grow toward the steam chamber of the SAGD pair, thereby accelerating development of communication between the SAGD pair and the offset well. This process is continued until fluid communication is established between the injection well and the offset well. The offset well is then converted to producing heated oil and steam condensate under steam trap control as steam continues to be injected through the injection well. The process yields improved oil recovery rates with improved steam consumption.

Title: Traction table
Inventor: BERRY ROBERT H
IPC: A61H1/02
Filed: 1999-08-16
Abstract: A table that corrects postures when looking at the anterior aspect of the person. The table will be mirror-imaging their postures including: Right and left head translations, right and left thoracic translations, and right and left lateral bending of the thorax. The table is made up of two movable sections (cervical and thoracic) and a stationary seat having a pelvic support. The head is placed in between two padded walls, and the cervical section is slid to one side and gets locked down, placing the head of the patient in the minor-image translation. The thorax of the person is strapped down to the thoracic support, which is then slid to one side and locked in place, causing the thorax to be in minor-image translation and/or lateral bending posture.

Patent CA-2290996-A1 (CA)
Inventor: PEPIN HENRY J
IPC: B29C48/09
Filed: 1998-06-08
Abstract: A guiding catheter or angiographic catheter and method of manufacture for use in cardiovascular interventions which incorporates an annealed low-flexibility proximal zone wherein a transition zone separates the proximal zone and a high-flexibility distal zone. The catheter is subjected to a slicking operation to improve the smoothness of the high flexibility distal zone in order to better traverse the aortic arch shape while reducing excess energy storage. The proximal zone is annealed to provide a high level of stiffness for optimal support and pushability. A mid-region zone transitions the high stiffness of the proximal zone to the higher flexibility of the distal zone to eliminate buckling and kinking.

Title: Hockey stick blade assembly
Inventor: HEYDUK HENRY
IPC: A63B59/70
Filed: 2000-01-10
Abstract: A hockey stick blade assembly for removable and replaceable installation onto a reusable hockey stick shaft comprises a blade member having a bottom blade portion and an upwardly extending hozel portion insertable into the hollow end of the hockey stick shaft. First and second co-operating wedging surfaces are operatively disposed on the hozel portion of the blade member and on an outer wall of the hockey stick shaft, respectively, and are shaped for wedging contact with each other. When the hozel portion of the blade member engages the hockey stick shaft, the first wedging surface imparts a substantially transverse first wedging force to the second wedging surface and the second wedging surface imparts an oppositely directed substantially transverse second wedging force to the first wedging surface, which wedging forces are transmitted to the outer walls of the hollow-ended hockey stick shaft. The outer walls deform slightly to absorb the opposed first and second wedging forces and thus impart corresponding inwardly directed opposed reaction forces against the first and second wedging surfaces, thereby forcing the first and second wedging surfaces into intimate frictional engagement one with the other, so as to retain the blade member in place on the hockey stick shaft.      A locking means is securely engageable between the blade member and the hockey stick shaft to preclude relative movement along a common longitudinal axis of the blade member and hockey stick shaft with respect to each other when the blade member is installed on the shaft.

Title: Cervical disk and spinal stabilizer
Inventor: PISHARODI MADHAVAN
IPC: A61F2/46
Filed: 1998-07-30
Abstract: A middle expanded, removable disk implant (22) for stabilizing adjacent cervical vertebrae (16, 18). The implant is substantially rectangular in cross-sectional shape with a niminal height (H) and a width (W) greater than the height. The implant is detachably mounted to an applicator for insertion into the anatomical region between two adjacent cervical vertebrae from which the intervertebral disk has been removed, and once inserted, is positioned by anterior-posterior movement in the disk space to the position in which both the expanded, larger width middle portion and the smaller diameter end portions of the implant engage the bodies of the adjacent vertebrae and the implant is then rotated to bring the sides of the rectangularly-shaped implant defining the width of the implant, with its larger dimension (W), into engagement with the bodies of the adjacent vertebrae. A lock, in the form of a stabilizer bar (29), is then secured to the implant to prevent further rotation thereof. The stabilizer bar includes structure which prevents relative rotation between the stabilizer bar and the implant and structure which protrudes into the space between the cervical vertebrae to prevent rotation relative to the vertebrae.

Patent CA-2312128-A1 (CA)
Inventor: SOVERO EMILIO A
IPC: H01P5/107
Filed: 2000-06-22
Abstract: An RF transition for coupling energy propagating in a waveguide transmission line into energy propagating in a monolithic microwave integrated circuit ("MMIC") is provided. The RF transition comprises a microstrip structure that includes a MMIC substrate with backside metallization and a front side microstrip. The backside metallization defines an iris, and the microstrip includes a microstrip feed formed proximate the iris. The RF transition also includes a waveguide terminating at the metallization layer around the iris to thereby convert energy propagating in the waveguide into energy propagating in the microstrip.  In one embodiment, RF signal processing circuitry is monolithically formed on the MMIC substrate. The invention enables a waveguide-to-MMIC transition to be constructed at higher RF frequencies, such as millimeter wave frequencies, even with the fragile, thinner substrates and smaller device features of higher-frequency devices. The monolithic structure avoids the use of wire bonds or ribbon welds to interconnect separate substrates, such as would be used in an MIC  implementation, enabling improved RF performance at higher RF frequencies. The invention enables an RF circuit to be constructed that is adapted to communicate signals with a waveguide at higher RF frequencies, such as millimeter wave frequencies, in a rugged, producible package.

Inventor: JOHNSTON GREGORY L
IPC: B60T17/04
Filed: 2000-07-13
Abstract: A purge valve for expelling liquid contaminants from a fluid conduit which is normally unpressurized but is at times pressurized with a gas which contains liquid contaminants. It has a housing, a diaphragm mounted within the housing, a control chamber on a first side of the diaphragm, an exhaust passage on a second side of the diaphragm and a valve seat surrounding the exhaust passage. The valve seat is positioned so that the diaphragm can seal against it. A spring on the second side of the diaphragm presses it away from the seat. An annular chamber is on the second side of the diaphragm, surrounding the exhaust passage. The annular chamber is open to the exhaust passage when the diaphragm is unseated from the valve seat. The valve has a low impedance flow path between the control chamber and the fluid conduit. The valve also has a high impedance discharge flow path connected to the annular chamber. The high impedance discharge flow path may be connected to the control chamber, connected to the low impedance flow path, or it may be for connection to the fluid conduit. When the valve is connected to the fluid conduit, it is open due to the spring force whenever the fluid conduit is unpressurized so that the liquid contaminant may drain from the valve. When the fluid conduit is pressurized, the diaphragm is pressed against the valve seat so that the valve is closed.
