Filed: 2001-05-01
Abstract: L'invention concerne un procédé et un appareil permettant à une structure de câblage pour réseau local de transmettre simultanément des données numériques et des signaux téléphoniques analogiques sur le même support de transmission. Cette invention convient en particulier à un réseau en étoile, dans lequel des unités de données à distance (p. ex. ordinateurs personnels) sont chacune connectées à un concentrateur à travers un câble comprenant au moins deux paires de conducteurs, fournissant une voie de communication de données dans chaque direction. Des modules à chaque extrémité du câble fournissent une voie fantôme pour signaux téléphoniques (bande vocale) entre un téléphone près d'un modem et un autocommutateur privé, à travers les deux paires de conducteurs dans un circuit fantôme. Toutes ces voies de communication fonctionnent simultanément et sans interférence mutuelle. Ces modules comprennent des composants de circuit passif simples et économiques.

Title: Cruciform parachute with arms attached
Inventor: BERLAND JEAN C
IPC: B64D17/02
Filed: 2001-08-22
Abstract: An improved cruciform or cross parachute is formed by attaching the adjacent  edges of the lateral arms (14, 16, 18, 20) to each other to form a three- dimensional canopy (10), when inflated, which is substantially square at the  top and substantially round at the lower edge. The attachment of the adjacen t edges of the arms are such as to provide generally vertical openings or vent s (36) through which air can flow outwardly from underneath the canopy, which form "corner air flow jets", thus allowing use of zero or near zero porosity  fabric for constructing the canopy. Attachment of the adjacent edges of the arms at their outer tips forms a continuous hem at the lower edge of the canopy which eases packing and improves reliability. Arm air flow jets of U. S. Patent No. 5,839,695 may also be included in addition to the corner air flow  jets formed by attaching the adjacent arm side edges. Air flow from undernea th the canopy through the air flow jets should be sufficient to achieve a degre e of flight stability for the parachute of .plusmn.50 , or less, when using a zero or near zero porosity fabric for the canopy.

Patent CA-2428058-A1 (CA)
Inventor: MARTIN ROY
IPC: C02F1/52
Filed: 2001-11-06
Abstract: A process for optimizing the rate of oxidation in aquatic facilities using a combination of halogen, e.g. chlorine donors and peroxygen, e.g. potassium monopersulfate. The peroxygen compound elevates the oxidation-reduction potential of the body of water being treated. Simultaneously, a halogen donor is added to the body of water to maintain a ppm level of free halogen sufficient to insure sanitization. The amount of free halogen is reduced and the ORP effective range expanded to 700 mV-850 mV by addition of an effective amount of a coagulating agent. The feed rates and concentrations of both oxidizers are optimized so as to achieve and maintain the targeted parameters. A high level of oxidation is maintained which removes by-products from the water and surrounding air.

Inventor: BRUN CLAUDE
IPC: B01J23/882
Filed: 2002-02-13
Abstract: The invention concerns a method for sulphurizing catalysts for hydrotreating of hydrocarbon feedstocks. The invention is characterised in that it consists in sulphurizing the catalyst in two steps: the first step consisting in sulphurization with tertiary mercaptan in the absence of hydrogen, and the second step, carried out consecutively in the same reactor, consisting sulphurization with another sulphurizing agent in the presence of hydrogen. The catalysts thus sulphurized prove to be more active than those sulphurized by only the second step.

Patent CA-2442431-A1 (CA)
Inventor: SMITH DOUGLAS WILBERT PAUL
IPC: C10L5/44
Filed: 2003-09-16
Abstract: This invention provides a method and apparatus to convert an organic fuel into heat in a manner that minimizes ash in the flue gas. The usual combustion process is segregated into multiple distinct and separated processes. The primary process of this invention is pyrolysis of the organic fuel in an oxygen free atmosphere. The organic fuel is handled sedately to prevent ash inclusion in the pyrolysis gases. The gases formed are directed to a separate combustion process. An additional process receives the carbon and ash solids from pyrolysis and uses air and water vapor to react with the carbon in a sedate manner to produce reduction gases for combustion separate from the reduction process. The reduction gases contain fewer ash particles than normal combustion. An optional process pre-dries the organic fuel and uses the moisture and fines from this pre-drying process to feed the reduction process.

Patent CA-2448332-A1 (CA)
Title: Multiple detection systems
Inventor: WHITEHOUSE CRAIG M
IPC: H01J49/40
Filed: 2002-05-24
Abstract: A particle detection system is configured and operated as two or more separate and completely independent detection systems (22, 23, 50, 51). The detection systems may be of the same or different design, may be operated in the same or different modes, and may be operated with the same or different operating parameters. Each detection system may record signals simultaneously, or alternately; measurement obtained from each of the detection systems may either be combined into a single unified data set, or recorded separately.  Means are provided to direct particles to impinge on one of the detectors or any of the other detectors. Alternatively, a population of particles can be dispersed in a manner that allows a population to be distributed among two or more detectors (22, 23, 50, 51) simultaneously. The implementation of completely independent detection systems, for example, in a Time-of-Flight mass spectrometer, allows the design and operation of each detection system (22, 23, 50, 51) to be optimized independently, while being employed simultaneously. The flexibility afforded by the apparatus and methods in the invention allows signals to be recorded (80) with enhanced signal dynamic range, signal-to-noise, and/or temporal resolution, relative to other presently available detection systems.
