Patent CA-2457472-A1 (CA)
Inventor: WECH MICHAEL J
IPC: G05D7/01
Filed: 2004-02-12
Abstract: The metering device for a liquid medium comprises a cylinder and a piston operatively disposed therein to define a metering chamber ahead of the piston. The outlet end of the cylinder is open and closed by an evacuation valve. The piston is driven forwardly through a working stroke to force the liquid medium in the metering chamber out of the chamber and past the evacuation valve. A check valve located in the metering chamber moves from a closed to an open position on each working stroke to preclude entrapment of air in the metering chamber and thus provide for more accurate metering. The metering device may include means to regulate the length of the working stroke.

Abstract: An ice-making machine which includes a plurality of heat exchangers disposed inside a housing, each heat exchanger having at least one inlet and outlet to permit circulati on of refrigerant therethrough. Each heat exchanger includes a plurality of thin sections of material arranged between a pair of thin outer plates. Each of the thin pieces of material is comprised of parallel flow paths, allowing for the refrigerant to flow through the inlet, then fro m one section to the next, and finally out the outlet. The arrangement of the sections of parallel flow paths allows for the refrigerant to come into contact with the majority of the inside wall of the outer plates, allowing for maximum heat exchange. In use, the heat exchangers are arranged parallel within the frame, with each side being sprayed with a liquid material to be frozen. A rotating scraping device sweeps across the surface of the plates, removing any ice crystals that have formed.

Title: Procede de traitement de l'infection par le virus de l'immunodeficience humaine (vih)
Inventor: KHAMAR BAKULESH MAFATLAL
IPC: A61K39/00
Filed: 2002-01-17
Abstract: Le virus de l'immunodéficience humaine entraîne la déplétion des cellules CD4, qui provoque à son tour une diminution de l'immunité chez un individu infecté. En raison de cette diminution de l'immunité, diverses infections opportunistes apparaissent qui sont un facteur de morbidité et de mortalité chez les individus infectés par le VIH. Le traitement du VIH fait appel à des médicaments antirétroviraux, lesquels médicaments possèdent des effets secondaires et permettent une reconstitution immunitaire qui est lente et différée. Plusieurs tentatives ont été faites pour améliorer la numération des CD4, notamment par l'utilisation de l'IL-2. L'utilisation de l'IL-2 est associée à des effets secondaires systémiques pendant la durée de son administration. La présente invention concerne un procédé selon lequel on utilise une mycobactérie w pour gérer le VIH. Selon la présente invention, la mycobactérie w administrée par voie intradermique est efficace dans la prophylaxie et le traitement du SIDA ou du syndrome apparenté au SIDA. Il a été découvert que la mycobactérie w améliore l'immunité et la numération des CD4 et élimine des symptômes tels que la fièvre et la diarrhée. Cet effet est observable même en l'absence de médicaments antirétroviraux.

Inventor: VERNON NICHOLAS M
IPC: A23L27/30
Filed: 2003-04-04
Abstract: The present invention relates to novel methods for stabilizing aqueous deacylation, via use of buffers in the production of sucralose. The present invention provides a process for producing sucralose from an acyl-sucralose compound whereby the acyl-sucralose compound is deacylated in the presence of a buffering agent, which stabilizes the pH of the feed mixture and decreases the accumulation of undesired anhydro compounds. Further, the present invention provides a process whereby the acyl-sucralose compound is deacylated directly either prior to or after removal of the tertiary amide reaction vehicle from the neutralized chlorination feed mixture. An aqueous solution of sucralose including salts and other compounds is produced, from which sucralose is recovered by extraction and purified by crystallization.

Patent CA-2486331-A1 (CA)
Inventor: SIGERUD KURT
IPC: F02M1/10
Filed: 2004-10-26
Abstract: An auto-enrichener for an all terrain vehicle, including an enriching conduit for carrying fuel and air to an engine, and a valve disposed in the conduit. The valve is adjustable between at least an open configuration and a closed configuration. In the open configuration passage of fuel and air through the conduit is enabled, and in the closed configuration passage of fuel and air through the conduit is not enabled. The auto-enrichener also includes a thermal expansion element in communication with the valve. The thermal expansion element expands with increasing temperature and contracts with decreasing temperature. The thermal expansion element actuates the valve such that when the thermal expansion element is at a first temperature the valve is in the open configuration, and when the thermal expansion element is at a second temperature greater than the first temperature the valve is in the closed configuration. The auto-enrichener also includes a heater in thermal communication with the thermal expansion element. The heater is operated when the engine is operated, so that the thermal expansion element is heated when the engine is operated. Consequently, the amount of additional air and fuel provided for enriching the engine corresponds to the temperature of the thermal expansion element, and also corresponds to the temperature of the engine.
