Title: Improved method and system for collecting and handling dust in a papermachine environment
Inventor: COURTNEY KEVIN
IPC: D21F5/00
Filed: 2000-04-06
Abstract: An improved process and system (22) for collecting and handling dust in a papermaking machine environment (20) wherein dust-laden air is drawn into and moves along an elongated collector (38 or 40) by way of a vacuum-generating source (42) connected to the collector involves the introduction of water into the collector so that the introduced water becomes entrained by the dust-laden air moving through the collector and wet-scrubs the dust-laden air upon entering the collector. With the dust being wet-scrubbed upon exiting the collector, the likelihood of ductwork fouling is substantially eliminated, and the risk of fire in the ductwork downstream of the collector is appreciably reduced.

Title: Mixing system for introducing and dispersing gas into liquids
Inventor: GIGAS BERND
IPC: B01F3/04
Filed: 1999-09-22
Abstract: A mixing system utilizes up pumping axial flow impellers (14, 16, 18) which entrain gas into the liquid both at the surface (12) and below the surface by induction to draw gas down below the surface where it is dispersed into the circulation produced by the impellers (14, 16, 18). Tubes (48) are disposed on the suction sides of the impeller blades (14, 16, 18), and provide gas outlets near the tips (50) of the blades (14, 16, 18).  The tubes (48) may extend along the shaft above the surface or into a hollow shaft having a breathing opening (46) above the surface (12). The rotation of the impellers (14, 16, 18) produces a suction at the tube outlets to draw gas into the liquid while the upward circulation produces surface turbulence for gas entrainment.

Patent CA-2354927-A1 (CA)
Inventor: WARREN DAVID W
IPC: C01B3/38
Filed: 2001-08-10
Abstract: A fuel processor apparatus comprising a catalytic tubular reactor is heated using an infrared radiant burner to provide the endothermic heat of reaction needed to reform a mixture of hydrocarbon and steam for the production of a hydrogen-rich gas stream. The hydrogen-rich gas stream is further purified using a sequence of catalytic steps and is fed to a fuel cell whereupon a portion of the hydrogen contained in said gas stream is consumed for the production of electricity by electrochemical reaction with oxygen. An unused portion of the purified hydrogen-rich gas stream exits the fuel cell stack and is combusted in said infrared radiant burner. A  fuel cell control system rapidly responds to a variable fuel cell electric demand by adjusting the feed of hydrocarbon to the catalytic tubular reactor to maintain the surface temperature of the infrared radiant burner within defined limits.

Title: Background synchronization for fault-tolerant systems
Inventor: BISSETT THOMAS D
IPC: G06F11/14
Filed: 2000-04-05
Abstract: An inactive memory is synchronized with an active memory in a fault-tolerant  computer system that includes an active processor. Data is copied from the active memory to the inactive memory using a background process that permits  the active processor to perform normal operations while the copying is proceeding. Regions of the active memory in which changes are made are track ed while the copying is proceeding, and, after copying is complete, a determination is made as to whether data from the regions of the active memo ry in which changes were made can be copied to the inactive memory within a predetermined time period using a foreground process that prevents the activ e processor from performing normal operations. If the data can be copied to th e inactive memory within the predetermined time period using the foreground process, the data is copied to the inactive memory using the foreground process. If the data cannot be copied to the inactive memory within the predetermined time period using the foreground process, the copying, trackin g, and determining are repeated for the regions of the active memory in which changes were made.

Title: Panneaux faits de pieces de bois emboitees

Abstract: L'invention vise des pièces de bois utilisables pour fabriquer des panneaux, comprenant chacune une surface inférieure, deux côtés latéraux et des tenons et mortaises ou des crochets et encoches sur les deux côtés latéraux de sorte que (1) l'on ait au moins un tenon ou crochet de chaque côté de chaque pièce et au moins une mortaise ou encoche correspondante de l'autre; et (2) les tenons ou crochets soient positionnés à une même hauteur entre les surfaces supérieure et inférieure de chaque pièce de bois et les mortaises ou encoche s soient positionnées à une autre même hauteur adaptée à celle où se trouvent les tenons ou crochets. Lorsque les pièces de bois sont ainsi taillées, il est alors requis que lorsqu'une pièce est placée à plat dans une position donnée avec une surface supérieure et une surface inférieure, la pièce adjacente soit alors placée e n position renversée, sa surface inférieure étant alors placée dessus et celle supérieu re dessous. Les pièces de forme identique sont donc emboîtables les unes dans l es autres en plaçant alternativement une pièce à l'endroit et une autre à l'envers.  Toutefois, du fait de cette configuration, chacune des pièces est orientab le longitudinalement dans un sens ou dans l'autre, à volonté. Ceci est très intéressant dans le cas où les pièces sont tailléesdans des troncs ou branches de forme générale conique, car on peut alors les positionner tête-bêche en alternance  pour fabriquer un panneau droit.
