Patent CA-2361125-A1 (CA)
Title: Device for diffusing sterile air
Inventor: BRIDENNE PIERRE
IPC: B65B55/18
Filed: 2000-01-25
Abstract: An installation includes a worktop, a first wall and a device for the close protection of products arranged on the worktop, whereby the products are sensitive to contamination from the ambient environment. The products are protected by diffusion of a sterile air stream in a direction substantially perpendicular or parallel to the worktop. The device extends along the worktop and has a least one end adjoining the first wall so that there is an air gap between the end and the first wall. The end is formed by a porous second wall made of perforated material, extending substantially perpendicular to a longitudinal axis of the device, in such a way as to create in the gap a sterile air leakage directed outward away from the worktop, whereby the sterile air leakage counters any ambient air induction into the gap toward the worktop.

Title: Apparatus and method providing alternate fluid flow path for gravel pack completion
Inventor: TIBBLES RAYMOND J
IPC: E21B43/04
Filed: 2001-12-13
Abstract: The present invention provides improved apparatus and methods for use in completing a subterranean zone penetrated by a wellbore. One aspect of the invention is an apparatus comprising a tubular member having a first segment and a second segment, each segment containing a longitudinal bore. The tubular member forms an annulus between itself and the wellbore wall. At least one screen member at least partially encloses and is coupled to a second segment of the tubular member. The screen member and the enclosed second segment of the tubular member both have openings that allow fluid communication between the longitudinal bore of the tubular member and the wellbore. The apparatus includes an alternate flowpath member having a wall, upper and lower ends, and at least one aperture in its wall. The apertures are small enough to substantially prevent passage of particulate material. The alternate flowpath member extends longitudinally along a portion of the wellbore and creates a communication path for fluid flow.

Patent CA-2368213-A1 (CA)
Title: Specifically targeted catalytic antagonists and uses thereof
Inventor: SANFORD KARL JOHN
IPC: A61K47/48
Filed: 2000-04-21
Abstract: The invention provides chimeric molecules that are catalytic antagonists of a target molecule. The catalytic antagonists of this invention preferably comprise a targeting moiety attached to an enzyme that degrades the molecule  specifically bound by the targeting moiety. The catalytic antagonists of thi s invention thus bind to a target recognized by the targeting moiety (e.g., a receptor) the enzyme component of the chimera then degrades all or part of t he target. This typically results in a reduction or loss of activity of the target and release of the chimeric molecule. The chimeric molecule is then free to attack and degrade another target molecule.

Abstract: A modular brassiere fitment apparatus may be provided for use in the determination of the brassiere size of a woman. The modular brassiere fitment apparatus has the same general appearance as an ordinary brassiere except that it is based on a modular system. The first module comprises a pair of breast cups, a connecting front panel, and two side panels. The second module comprises a back panel. A third module may comprise a pair of shoulder straps. At least two first modules and at least two second modules make up a modular brassiere sizing kit where each of the first modules has a different size and each of the second modules has a different size, one from the other. When one of the first modules is assembled to one of the second modules from the modular brassiere sizing kit, the combination of the first and second modules constitutes a modular brassiere fitment apparatus. With the use of the modular brassiere sizing kit, the woman is able to mix and match different first modules and different second modules until she finds a combination that gives her a correct fit. Once the correct size of each of the first and second modules has been determined, the woman may easily purchase brassieres which will be comfortable and fit properly. When sizing, the first module will give a measurement of the woman's bust while the second module will give a measurement of her midriff. On combining the two sizes, the woman then determines her brassiere size.

Title: Method and apparatus for seating tubeless tires
Inventor: DEMERS NORMAN P
IPC: B60C25/14
Filed: 2000-05-03
Abstract: A method and apparatus for bead seating a tubeless tire onto a rim comprising a charging reservoir (22) having a fill/quick-release port (51), an inlet (42) and an outlet (97). A piston (36) divides the charging reservoir into a control section (89) and an outlet section (87). A portable tank (12) having a stored air is connected to the outlet section (87). A pressure differential across the piston keeps the piston tightly against the outlet, holding the pressurized air in the outlet section and the portable tank. Once the pressurized air in the quick-release section is released, the piston is propelled away from the outlet, thereby explosively releasing the air as a single pneumatic pulse and directed towards a unique nozzle (66) to seat the bead of the tire.

Patent CA-2381442-A1 (CA)
Inventor: DUTTA ALOK
IPC: F03B17/00
Filed: 2002-04-17
Abstract: The invented machine mainly consists of a pendulum set-up, two magnetic guides and two sets of pipes (each set made of a male pipe and a female male pipe) and three fluid reservoirs. The pendulum set-up swings by gravitational force guided by the magnetic set-up. The pendulum set up is attached with two sets of male and female pipe. The two male pipes move up and down in turn by the swing of the pendulum set-up, and the movement of male pipes lifts the system fluid (water) up from the bottom reservoir to the top reservoir. The fluid at the top reservoir falls freely and hits upper turbine and lower turbine successively. The electricity produces by the rotation of turbines through the mechanical set-up.
