Title: A combined heat and power plant and a process for the operation thereof
Inventor: WIELAND STEFAN
IPC: H01M8/06
Filed: 2002-04-02
Abstract: The invention provides a combined heat and power plant with an integrated gas production system. The combined heat and power plant contains a steam reformer heated with a gas burner which converts a mixture of hydrocarbons and water vapour into a reformate gas stream containing hydrogen and carbon monoxide. The plant further contains a reactor system with several stages for removing carbon monoxide from the reformate gas stream. The plant also contains a heat exchanger for removing heat energy from the reformate gas stream and a fuel cell unit for producing electrical energy by catalytic reaction of the hydrogen contained in the reformate gas with oxygen in the fuel cell, wherein the reformate gas stream is supplied to the anode in the fuel cell unit and the anode waste gas is taken to the gas burner of the steam reformer as fuel, via a gas pipe. The reactor system for removing carbon monoxide from the reformate gas stream contains, according to one embodiment of the invention, a low temperature shift reactor and a downstream methanisation reactor and the heat exchanger for cooling the reformate gas stream leaving the steam reformer to the inlet temperature of the low temperature shift reactor is located in the reformate gas stream between the steam reformer and the low temperature shift reactor. This combined heat and power plant is operated according to the invention in such a way that the reformate gas contains 5 to 10 vol.% of unreformed hydrocarbon which enables the flame in the gas burner to be monitored using an ionisation detector when burning the anode waste gas in the gas burner of the steam reformer.
Patent CA-2380288-A1 (CA)
Inventor: MCCORMICK ALLYN L
IPC: C04B35/573
Filed: 1999-07-23
Abstract: Improved silicon carbide composites made by an infiltration process feature a metal phase in addition to any residual silicon phase. Not only are properties such as mechanical toughness improved, but the infiltrant can be so engineered as to have much diminished amounts of expansion upon solidification, thereby enhancing net-shape-making capabilities. Further, multi-component infiltrant materials may have a lower liquidus temperature than pure silicon, thereby providing the practitioner with greater control over the infiltration process.  In particular, the infiltration may be conducted at the lower temperatures, where low-cost but effective bedding or barrier materials can terminate the infiltration process once the infiltrant has migrated through the permeable mass up to the boundary between the mass and the bedding material.

Title: Methode de phagocytose in vitro pour la prevision du potentiel in vivo d'antagonistes/agonistes d'intergrines en vue de l'induction de la thrombocytopenie
Inventor: REILLY THOMAS M
IPC: G01N33/80
Filed: 2000-10-12
Abstract: L'invention concerne l'utilisation d'une méthode de phagocytose in vitro basée sur les cellules en vue de déterminer le potentiel des antagonistes ou agonistes d'intégrines nécessaire à l'induction de la thrombocytopénie. Cette méthode consiste à mesurer l'étendue de la phagocytose dans des échantillons contenant (i) des plaquettes, (ii) un antagoniste ou agoniste d'intégrine et (iii) un échantillon connu pour contenir des anticorps anti-plaquettes présentant une dépendance aux médicaments d'antagoniste ou agoniste d'intégrine ou un échantillon pouvant contenir lesdits anticorps. Le processus de phagocytose de cette méthode est de préférence mesuré au moyen de chimiluminescence ou de colorants. La méthode est utilisée dans le criblage d'antagonistes/agonistes d'intégrine, telles que les antagonistes de récepteur (GPIIb/IIIa) de glycoprotéine IIb/IIIa, pour leur potentiel de phagocytose et donc de thrombocytopénie, en présence d'anticorps présentant une dépendance aux médicaments. On utilise ces méthodes pour identifier des patients qui peuvent présenter le risque de développer une thrombocytopénie médiée par un traitement avec un antagoniste ou un agoniste d'intégrine. La méthode décrite dans cette invention est utile à l'identification de nouveaux antagonistes ou agonistes d'intégrine qui n'assurent pas la médiation de la liaison des anticorps présentant une dépendance aux médicaments vers des plaquettes et ainsi que celle de la thrombocytopénie.

Title: Efficient detection of general paging messages in poor signal to noise environments
Inventor: BAYLEY GWAIN
IPC: H04B1/16
Filed: 2001-03-30
Abstract: A method of and an apparatus for reduc-ing the average power consumption in a remote unit in a wireless communication system. When a remote unit in a slotted mode communication system enters an ac-tive state, it receives a sequence of messages. One ele-ment of this sequence is a general paging message that command the remote unit to return to the inactive state immediately, thus conserving battery power. The gen-eral paging message is followed by several additional el-ements in the sequence. When the remote unit operates in a poor signal-to-noise ratio environment, for example, it may not receive the general paging message and may, thus, unnecessarily remain in the active state until the end of its assigned slot, wasting battery power. The invention determines whether the element received by the remote unit is a general paging message. If so, the remote unit enters the inactive mode. If not, the invention determines whether the element occurs after a general paging mes-sage in the sequence of messages. If so, the remote unit enters the inactive mode without waiting for the end of the assigned slot.
