Title: Procede servant a produire de la chaleur
Inventor: GOUGH ARTHUR
IPC: C07C5/32

Granted: 2003-04-01
Abstract: Un échangeur de chaleur est constitué par deux plaques ou étages (4) et (6), l'étage (4) étant placé au sommet de l'étage (6) et une pluralité de ces échangeurs de chaleur étant empilés les uns au-dessus des autres. L'étage (4) possède une ouverture d'entrée (14), un passage d'entrée (28) et des passages (22) étant ouverts à l'extrémité (26) de l'étage. L'étage (6) possède une ouverture d'entrée (36) conduisant aux passages (52) menant à un passage de sortie (58) et à une ouverture de sortie (40). L'étage (6) possède également une ouverture d'entrée (38) conduisant aux passages (64) comportant une sortie à l'extrémité (68). Un gaz combustible, par exemple un gaz matériel et un oxydant, pénètrent dans la zone de passage (30) de l'étage (4), dans laquelle le mélange est préchauffé, puis passe vers la zone de passage (32) de l'étage (4). Ces parties de passage de gaz (22) dans la zone de passage (32) contiennent un catalyseur de combustion, de sorte que le gaz combustible et le mélange oxydant se consument dans la zone de passage (32). Les produits de combustion sont évacués par l'extrémité de sortie (26) et sont transportés vers l'entrée (38) de la zone de passage (46) de l'étage (6) comprenant les passages (64). La chaleur émanant de la zone de passage (46) préchauffe encore le gaz combustible et l'oxydant pénétrant dans la zone de passage (30). Le fluide pénétrant dans la zone de passage (44) à travers l'entrée (36) extrait de la chaleur de combustion depuis la zone de passage (32), ce fluide pouvant, soit subir une réaction endothermique dans la zone de passage (44), soit acquérir de la chaleur sensible. Dans les deux cas, le(s) produit(s) obtenu(s) sont évacués de la zone de passage (44) par la sortie (40).

Abstract: A process of the kind used for producing or repairing a turbine or compressor or fan blade by laser consolidation wherein a laser beam is moved relative to a metal surface and a stream of metal is supplied to the surface via a supply tube, so that said laser beam melts a thin layer of the metal substrate and also melts the metal being delivered to the substrate and thus forms a band of fused metal on said surface, the process being repeated until a desired blade is built up or repaired. The invention is characterized in that the laser beam is orientated at an acute angle to the surface. The supply tube may deliver the metal substantially along a path normal to the surface, with the laser beam being one of a plurality of laser beams each orientated at an acute angle to the surface and spaced around the supply means. Alternatively, a single laser beam may be used at a first acute angle to the surface, with the supply tube being at a second acute to the surface, the laser beam and supply tube being at opposite sides to the normal to the surface.

Abstract: An MMS circuit set-up system includes a real time link manager (RTLM, 50) which is coupled to the audio video controller (AVC, 74) of the MMS. The AVC (74) receives data from MMS reservation system and sends commands to the RTLM (50) to set up connections for the conference. The RTLM (50) sends configuration messages to ATM switch es and/or other networking equipment using SNMP in order to set up a conference using SNMP via an ETHERNET connection to the slot controllers of the ATM switches and networking equipment which does no support SNMP. The ATM switches are controlled by the RTLM (50) using TCP/IP via an ETHERNET connection to the servers. The ATM circuits are preferably created by adding entries to an SPVC table in the ATM switch. According to one aspect of the invention, when ATM circuits are no longer needed, the SPVC table entries are not deleted, but the status of the circuit is marked "idle". This allows the circuit to be reused with minimal set-up time when i t is again needed.

Abstract: Elemental sulfur is recovered from the H2S present in natural gas and other process gases in a reaction scheme that combines a liquid-phase reactor, a furnace and an SO2 absorber. The reactor reacts the H2S with SO2 using excess H2S in the liquid phase in the presence of a homogeneous catalyst, and the SO2 is supplied to the reactor b y combusting the unreacted H2S in the furnace, recovering the SO2 from the combustion gas in an absorber and directing the recovered S O2 to the reactor. The reaction scheme produces no reaction products other than S and H2O.

The vacuum hose, when stored, is retained in a recess in the shroud which also serves as a carrying handle for the apparatus. The vacuum impeller drive motor is mounted in a housing assembly including separable tank cover, motor base and motor housing members. The motor base and tank cover form a discharge volute chamber for the vacuum impeller. Motor cooling air inlet and discharge passages are formed by and between the motor housing member and the shroud.

Abstract: Procédés de transport transdermique amélioré, selon lequel il est nécessaire d'appliquer des ultrasons une fois seulement en vue d'une extraction ou administration transdermique répétée ou prolongée sur une certaine durée, plutôt qu'avant chaque extraction ou administration. Ledit procédé peut être mis en oeuvre aussi bien pour l'extraction d'analytes que pour l'administration de médicaments. Il consiste à appliquer initialement une certaine quantité d'ultrasons basse fréquence efficaces pour perméabiliser la peau ou la membrane, ladite application étant suivie par l'extraction d'analytes ou l'administration de médicaments sur une certaine durée. L'application initiale d'ultrasons est efficace pour perméabiliser la peau ou la membrane pendant au moins environ 30 minutes, de préférence pendant au moins une à deux heures, et idéalement jusqu'à quatre à dix heures. Les ultrasons sont de préférence des ultrasons basse fréquence, de moins de 2,5 MHz, idéalement de moins de 1 MHz. Le transport transdermique peut être favorisé par l'application d'une force d'entraînement secondaire, telle que la succion, le gradient de pression osmotique, le gradient de concentration, l'ionophorèse, l'électroporation, les champs magnétiques, des ultrasons supplémentaires ou la pression mécanique.

Abstract: Continuously variable headlamps offer greater flexibility for roadway illumination but offer challenges in automatic control design. Each continuously variable headlamp has an effective illumination range varied by changing at least one parameter from a set including horizontal direction aimed, vertical direction aimed, and intensity emitted. A system for automatically controlling continuously variable headlamps on a controlled vehicle includes an imaging system capable of determining lateral and elevational locations of headlamps from oncoming vehicles and tail lamps from leading vehicles. The system also includes a control unit that can acquire an image from in front of the controlled vehicle. The image covers a glare area including points at which drivers of oncoming and leading vehicles would perceive the headlamps to cause excessive glare. The image is processed to determine if at least one oncoming or leading is within the glare area. If at least one vehicle is within the glare area, the headlamp illumination range is reduced. Otherwise, the headlamp illumination range is set to full illumination range.

Abstract: A managing method for a re-order buffer in an out-of-order execution processor for predicting the flow of a program by branch prediction comprises determining a next executable instruction from an instruction string in the program and speculatively executing the instruction on the basis of a dependence relationship between the prediction and the instruction. The re-order buffer re-writes an execution result according to a program order, and the end of the instruction is notified from function units containing a branch unit and a load unit to the re-order buffer by using an entry number buffer. The load unit manages the latest speculation state of a load instruction based on a branch prediction success/failure signal from the branch unit but does not provide notification to the re-order buffer based on the entry number for subsequent load instructions which the branching prediction has failed, even if processing of the instruction has finished.
