Patent CA-2387569-A1 (CA)
Inventor: BEYER DAVID A
IPC: H04L12/56
Filed: 2000-10-16
Abstract: One or more labeled routing trees (LRTs) are produced at a router of a computer network according to a shortest path determination made over a partial topology graph of the network, which graph is produced according to knowledge of adjacent links of the router and or more LRTs of neighboring routers. The LRTs of the router may be updated in response to receipt of routing state update messages, and such messages may include local link identifiers assigned by a head of a link to which the identifiers pertain, and node parameters of a tail of the link to which the local link identifiers pertain.  The routing state update messages may be transmitted within the network: (i) in response to a new destination node being detected by an existing node within the network, (ii) in response to a destination becoming unreachable by a collection of the existing nodes, (iii) in response to the change in the cost of a path to at least one destination exceeding a threshold and/or (iv) in situations where a routing loop may be encountered among two or more of the nodes of the network (e.g., at times when a path implied in the LRT of the router leads to a loop).

Title: Wavelength router
Inventor: GEORGIS STEVEN P
IPC: H04B10/43
Filed: 2000-11-14
Abstract: A wavelength router that selectively directs spectral bands between an input  port (12) and output ports (15). The router includes a free-space optical train disposed between the input ports and said output ports, and a routing mechanism (30). The free-space optical train can include air-space elements (20, 25) or can be monolithic construction. The optical train includes a dispersive element (25) such as a diffraction grating, and is configured so that the light from the input port encounters the dispersive element twice before reaching the output ports. The routing mechanism (30) includes one or  more routing elements and cooperates with the other elements (37) in the optical train to provide optical paths that couple subsets of the spectral bands to desired output ports.

Title: Method and apparatus for combustion of residual carbon in fly ash
Inventor: CRAFTON PAUL M
IPC: F23J15/02
Filed: 2000-11-02
Abstract: A system for combustion and removal of residual carbon within fly ash particles (F) in which the fly ash particles are fed into a particulate bed (40) within a reactor chamber (21). The fly ash particles are subjected to heat and motive air (37) such that as the fly ash particles pass through the particulate bed, they are heated to a sufficient temperature to cause the combustion of the residual carbon within the particles. The fly ash particles thereafter are conveyed in a dilute phase (28) for further combustion through the reactor chamber away from the particulate bed and exhausted to an ash capture (45). The fly ash is then separated from the exhaust air that conveys the ash in its dilute phase with the air being further exhausted and the captured fly ash particles being fed to a feed accumulator (80) for re-injection to the reactor chamber or discharged for further processing.

Abstract: Procédé/dosage destiné à la détection de diverses formes agrégées du peptide amyloïde en utilisant des sondes spectroscopiques spécifiques aux amyloïdes telles que le rouge de Congo et les analogues correspondants. Ce dosage peut s'utiliser pour faire une estimation de l'état d'agrégation du peptide en présence d'autres inhibiteurs potentiels de la fibrillogenèse; il constitue un modèle utile permettant de tester les inhibiteurs d'agrégation dans des modèles in vitro. Les résultats de ce dosage peuvent être utiles pour déterminer le stade auquel on peut intervenir dans le processus d'agrégation pour réduire la toxicité du peptide amyloïde vis-à-vis des cellules neurales. Dans des exemples concrets, on utilise le dichroïsme circulaire, l'absorption des U.V. et la spectroscopie par fluorescence pour évaluer la forme d'agrégation du peptide  beta -amyloïde.

Patent CA-2396853-A1 (CA)
Inventor: SPENCE EDWARD
IPC: B01D61/20
Filed: 2001-01-11
Abstract: The present invention provides a hemodialysis or hemodiafiltration system an d method using two dialyzer stages (122, 138), wherein the temperature of a dialysate fluid stream of the first cartridge (122) is increased such that t he blood in the first cartridge (122) is dialyzed or diafiltered at an elevated  temperature, while blood in the second cartridge (138) is dialyzed or diafiltered against a dialysate stream at normal blood temperature. This results in an increased solute diffusivity and a corresponding increase in removal of blood substances by diffusion. When diafiltration is performed, a n additional removal of substances occurs by convection as a larger portion of  plasma water from a blood compartment (142) can be filtered across a semi- permeable membrane (140) at the same transmembrane pressure due to the reduc ed viscosity of the heated blood and plasma water.
