Patent CA-2371004-A1 (CA)
Title: Flue gas scrubbing apparatus
Inventor: MENGEL MICHAEL L
IPC: F23J15/02
Filed: 2000-04-21
Abstract: An apparatus and process for removing acidic gases from flue gases produced by processing operations of the type carried out in utility and industrial plants. The apparatus is generally a gas-liquid contactor (10) whose operation involves the entrainment of a contact medium in an upward-flowing, high-velocity flue gas so as to promote the removal of constituents from the gas. While substantially complete removal of the entrained contact medium is problematic for the high-velocity flue gas, the apparatus, prior to demisting of the gases, redirects the gases containing the entrained contact medium from the upward flow direction to a downward flow direction so as to impact a body (22) of fluid in a container (18), and the gases are then flowed horizontally through a horizontal flow passage (30) at a reduced velocity to further separate the entrained contact medium from the gases.

Abstract: L'invention concerne un procédé permettant de convertir des données bidimensionnelles, notamment des informations en format HTML, en une représentation canonique servant à produire des formes sonores ou d'autres visuelles, où chaque élément d'intérêt est sélectionné en fonction de son appartenance à une expression régulière mathématiquement, notamment toute expression qui peut être analysée dans un arbre. Pour réaliser la sélection, le contenant de l'élément est localisé, et puis la route locale de l'élément à l'intérieur de l'arbre syntaxique est suivie, de telle manière qu'une signature de l'élément construit à partir de cette identification peut être élaborée et stockée en vue d'une utilisation ultérieure lors de l'extraction et de la traduction de la valeur de l'élément d'intérêt. Ce dernier peut alors être traduit par un traducteur de langage adéquat au demandeur. Une autre subtilité du procédé de cette invention repose sur la recherche d'éléments répétés et le stockage subséquent d'un desdits éléments sélectionnés, tel que le premier élément répété.

Title: A process for preparing an anode catalyst for fuel cells and the anode catalyst prepared therewith
Inventor: RUTH KARSTEN
IPC: B01J23/40
Filed: 2002-05-23
Abstract: The invention provides a process for preparing a platinum-ruthenium catalyst and the catalyst prepared therewith. The catalyst can be supported on a support material in powder form or may also be unsupported. To prepare the supported catalyst, the support material is suspended in water and the suspension is heated to at most the boiling point.      While keeping the temperature of the suspension the same, solutions of hexachloroplatinic acid and ruthenium chloride are then added to the suspension, then the pH of the suspension is increased to a value between 6.5 and 10 by adding an alkaline solution and the noble metals are thus precipitated onto the support material. Afterwards, one or more organic carboxylic acids and/or their salts are added to the suspension and the catalyst is chemically reduced, washed, dried and optionally subsequently calcined under an inert or reducing atmosphere at a temperature between 300 and 1000 °C. The catalyst is characterised by a high tolerance to carbon monoxide poisoning in the fuel cell.

Title: Silicon nanoparticle microcrystal nonlinear optical devices
Inventor: NAYFEH MUNIR H
IPC: H01S5/30
Filed: 2001-05-17
Abstract: Harmonic incident radiation is obtained from a silicon nanoparticle microcrystal (10) or microcrystal film. The silicon nanoparticle microcrystals are formed from silicon nanoparticles of about 1 nm and having about 1 part per thousand or less larger than 1 nm. The preferred film comprises silicon nanoparticles, dimensioned on the order of one nanometer, reconstituted into a device quality crystalline film. The microcrystal film emits the second harmonic of incident radiation for excitation in the range of about 600 -- 1000nm. A preferred device according to the invention includes a silicon nanoparticle microcrystal film formed on a substrate, such as silicon or glass. Crystals of the silicon nanoparticles, due to the harmonic response, also demonstrate the capability to serve as piezoelectric material and as an improved biological marker. Since the emission response of the silicon nanoparticle crystals will be influenced by surrounding electric fields, the microcrystals also provides for electrochromatic mapping of electric field distribution in general and in electronic devices.

Title: Pancreatic islet cell growth factors
Inventor: GONEZ LEONEL JORGE
IPC: A61K35/12
Filed: 2001-02-16
Abstract: The present invention relates generally to growth factors and more particularly to growth factors which are capable of stimulating or otherwise facilitating formation of insulin-secreting cells. The identification of these growth factors permits the development of protocols to culture cells in vitro for transplantation into mammalian and in particular human subjects with insulin-dependent type 1 diabetes or related conditions. It is further contemplated that the endogenous expression of growth factors required for the development of insulin-producing cells may be manipulated in vivo, by the appropriate administration of agents including genetic agents capable of regulating the expression of growth factors in pancreatic duct epithelial cells. The growth factors may also be administered to subjects with type 1 diabetes to stimulate the proliferation and differentiation of pancreatic cells into insulin-secreting cells. The present invention also provides modulators of growth factor-mediated pancreatic cell differentiation. Such modulators are useful in the treatment inter alia of .beta. cell tumors and/or pancreatic cancer.

Abstract: A system for monitoring and controlling power demands in devices with DC power supplies is disclosed. A device includes a control means responsive to a monitoring means. If the output voltage of the power source detected by the monitoring means falls below a first predetermined level, the power requirements of the device are reduced by the control means. If the output voltage level detected by the monitoring means falls further below a second predetermined level, the second level being lower than the first level, the control means shuts down the device. This approach has application to battery powered devices, particularly for medical applications such as cochlear implants.
