Title: Micromilling plant sterols and emulsifiers
Inventor: LIS DANIEL GERARD
IPC: A23L27/60
Filed: 2000-11-09
Abstract: Plant sterols have been shown to be cholesterol-reducing agents in human serum. In the present invention, plant sterols, plant stanols, plant sterol esters and other non-toxic sterols are micromilled with emulsifiers in a solvent (water or edible oil) to produce dispersion which can be incorporated into full-fat, reduced-fat, low-fat, fat-free and triglyceride- free food products. Such water-based or edible oil-based dispersions can be used to incorporate relatively high levels of such sterols/stanols in food products without the adverse organoleptic effect normally associated with the use of such plant sterols and plant stanols.

IPC: A61B18/14
Filed: 1999-05-26
Abstract: An improved electrosurgical instrument is disclosed and claims which includes a reusable electrode shaft (14), a disposable tip (16) and a novel, insulated coupling (18) for removably connecting the disposable tip to the electrode shaft.

Patent CA-2355414-A1 (CA)
Inventor: KHOSROWYAR PARVIZ
IPC: C07C29/80
Filed: 2001-08-16
Abstract: An improved method and apparatus for oxidizing undesired compounds residing within a liquid glycol based absorbent wherein the compounds are heated within a reboiler chamber to their boiling point to effectuate the production of vaporized effluents. Once so heated the absorbent 's vaporized effluents rise upwardly exiting the reboiler chamber and enter a reflux tower wherein they are partially condensed via a condenser means embodied within the interior of the tower. The residual uncondensed effluents are then transported to and first heated via a vaporizer / heat exchanger in heat exchange, thus effectuating the vaporization of any ambient condensed liquids contained within the effluents.  The revaporized effluents then enter the invention's thermal oxidizer combustion chamber where they are second heated to a temperature necessary to effectuate destruction of undesirable compounds, such as but not limited to benzene, toluene and xylene. The combustion chamber includes a burner fed as necessary by supplemental fuel, such as natural fuel gas. A temperature control throttling mechanism throttles the introduction of such gas as necessary to maintain the temperature necessary to effectuate and maintain destruction of undesirable compounds. A specially designed reduced diameter section of the combustion chamber enhances the mixing process of effluents traversing the chamber. The combustion chamber is in fluid communication with a plurality of tubes which pass through the reboiler. The tube bundle generates external tube surface temperatures sufficient to raise a liquid glycol based absorbent in contact therewith to its boiling point. The second heated effluents are then introduced to and through a thermal oxidizer vent stack allowing for the exiting of said effluents from the combustion chamber at 90À angle to effectuate a redirection of flow which serves as an additional mechanism to improve oxidation efficiency.  Venting mechanisms located in the invention's still / reflux tower and oxidizer vent stack are controlled in a coordinated manner to ensure temperature consistency of effluents traversing the invention's internal combustion chamber and tube bundle. An alternative embodiment of the present invention would allow the further utilization of an optional glycol heat recovery section and/or sparging or stripping pipe whereby rich glycol containing undesirable compounds is first introduced and routed through the optional heat exchanger, prior to entering the reboiler section of the instant invention. The optional sparging or stripping pipe of the invention provides a means by which stripping gas percolates through a regenerated liquid glycol based absorbent to vaporize and remove water. The stripping gas then exits through the top of the sparging or stripping pipe where it meets and mixes with other gases and vapors.
Patent CA-2358170-A1 (CA)
Inventor: KENNEDY LAWRENCE CHARLES
IPC: F16J1/18
Filed: 2001-10-01
Abstract: In a piston engine, end play of the piston pin can be prevented without unduly shortening the pin. In the simplest design (fig. 4), a full length piston pin can have spherical end surface in close clearance spacing relative to the combustion chamber surface, so that any tendency of the pin to shift along the pin axis is immediately resisted by contact between a spherical end surface and the combustion chamber surface. The area of each spherical surface is sufficient to prevent wear or scratching of the combustion chamber surface.   An alternative full length piston pin design incorporates spherical sheet-metal caps snapped in place at the ends (fig. 2), which fix the pin (and caps) from coming into contact with the cylinder bore wall.
