Title: Inflatable thermal blanket with a multilayer sheet
Inventor: HALL DOUGLAS ARNOLD
IPC: A47G9/02
Filed: 2000-01-25
Abstract: An inflatable thermal blanket (100) with a multilayer sheet (104) and a method of use are disclosed for delivering thermally-controlled air to a person. The apparatus includes an inflatable structure formed from joining a first sheet and a second sheet. An inlet (108) is provided into the inflatable structure for receiving thermally-controlled air. A  multilayer sheet, made from a plurality of sheets (106) releasably attached together, is attached to the second sheet. Means are provided for exhausting the thermally-controlled air from the inflatable thermal blanket. In the method of use, the inflatable thermal blanket is deployed in a first use and a source of thermally-controlled air is attached to the inflation port (108) admitting thermally-controlled air into the inflatable structure and exhausting thermally-controlled air. Additionally, the inflatable thermal blanket may be reused by detaching the lowest layer (106) of the multilayer sheet, exposing another layer of the multilayer sheet and deploying the inflatable thermal blanket in a second or later use. These steps may be repeated until the last layer (122) of the multilayer sheet is used when the thermal blanket may be discarded. In an alternate embodiment, when the multilayer sheet is exhausted it is detached and another multilayer base sheet is attached to the inflatable structure and the thermal blanket is used again.

Abstract: L'invention concerne des procédés, des systèmes et des réseaux de communications destinés à assurer une protection dans un réseau optique. Dans une réalisation, l'invention concerne un noeud source comprenant un système de commutation à répartiteur optique comportant une carte de port source dotée d'un séparateur permettant de diviser un signal optique entrant en deux signaux optiques semblables. Les deux signaux optiques semblables contiennent la même information. Un dispositif de commutation optique de source permet de commuter, respectivement, un des deux signaux optiques semblables vers une première carte de port destination puis vers un noeud adjacent, et l'autre des deux signaux vers une seconde carte de port destination puis vers un noeud adjacent différent, de telle façon que les deux signaux optiques semblables soient alors acheminés différemment dans le réseau optique. Un noeud destination, comportant un système de commutation à répartiteur optique, reçoit respectivement les deux signaux optiques semblables via des première et seconde cartes de port destination. Le système de commutation à répartiteur optique du noeud destination comprend un dispositif de commutation optique de destination destiné à commuter chacun des deux signaux optiques semblables vers une carte de port destination possédant un commutateur sélecteur. Ce commutateur sélecteur permet de sélectionner un des deux signaux optiques semblables disponibles, de telle façon que, si l'un des signaux optiques semblables différemment acheminé n'arrive pas à atteindre le noeud destination, en raison d'une défaillance dans le réseau optique, l'autre de ces signaux soit toujours disponible. Ainsi, la même information est assurée sur la carte de port destination du noeud destination et une protection optique 1+1 est mise en place sur le réseau optique.

Title: Method and apparatus for a catalytic firebox reactor
Inventor: PFEFFERLE WILLIAM C
IPC: F23M5/08
Filed: 2000-03-31
Abstract: A catalytic firebox reactor employing an exothermic catalytic reaction channel and multiple cooling conduits for creating a partially reacted fuel/  oxidant mixture. An oxidation catalyst is deposited on the walls forming the boundary between the multiple cooling conduits and the exothermic catalytic reaction channel, on the side of the walls facing the exothermic catalytic reaction channel.  This configuration allows the oxidation catalyst to be backside cooled by any fluid passing through the cooling conduits. The heat of reaction is added to both the fluid in the exothermic catalytic reaction channel and the fluid passing through the cooling conduits. After discharge of the fluids from the exothermic catalytic reaction channel, the fluids mix to create a single combined flow. A further innovation in the reactor incorporates geometric changes in the exothermic catalytic reaction channel to provide streamwise variation of the velocity of the fluids in the reactor.
