Patent WO-0124195-A1 (WO)
Title: Systeme d'amelioration de puissance critique destine a un reacteur nucleaire pressurise du type a canal de combustible faisant intervenir l'alignement des paires de grappes de combustible
Inventor: GROENEVELD DE C
IPC: G21C3/14
Filed: 2000-09-20
Abstract: La présente invention concerne un système d'amélioration de la puissance de canal critique (Critical Channel Power/CCP), destiné à un réacteur nucléaire pressurisé refroidi par eau du type à canal de combustible conçu pour être réapprovisionné en direct par insertion et retrait des grappes de combustible dans ou à partir d'une pluralité d'ensembles de canaux de combustible. Un élément sert à assembler les grappes de combustible en paires de sorte que leurs éléments de combustible se trouvent alignés, ce qui permet de diminuer la résistance hydraulique dans le canal de combustible et d'améliorer la CCP. L'élément d'assemblage permet d'éviter le mauvais alignement des grappes regroupées par paires durant leur temps de séjour à l'intérieur du réacteur, le mauvais alignement étant dû à l'oscillation et la vibration continuelle des grappes de combustible soumises à de très importants débits massiques de caloporteur, et dû à la séparation axiale des grappes lorsqu'elles s'entrechoquent durant les opérations d'approvisionnement.

IPC: F16F1/42
Filed: 2003-10-01
Abstract: Matériaux tampon utilisables pour la construction de planchers, de plafonds ou de parois. Pour la construction de planchers, on emploie généralement une pièce métallique en forme de U qu'on place entre la solive de plancher et le matériau couvre-plancher, si bien que les deux extrémités de la pièce métallique en forme de U maintiennent des positions généralement espacées. La pièce métallique peut également être courbée davantage pour adopter une forme généralement en accordéon. Les extrémités du métal peuvent être enroulées autour de la solive de plancher pour assurer un ajustage plus sûr et contribuer à la réduction de la transmission acoustique. Une vis ou un moyen de fixation similaire est utilisé pour fixer le matériau couvre-plancher à la solive de plancher. Des bandes d'atténuation du bruit, telles que du caoutchouc (c.-à-d. provenant de pneux recyclés) ou du plastique, peuvent en outre être utilisées pour réduire davantage la transmission acoustique. Les matériaux tampon de l'invention peuvent être utilisés de manière similaire pour la construction de plafonds ou de parois.

IPC: H04Q11/04
Filed: 1989-11-30
Abstract: Abstract A computer connected to an ISDN central office switch via an ISDN digital subscriber line, provides management information regarding activities of a plurality of telephone agents. The computer has shared call appearances with a number of telephone agent stations and receives shared call appearance associated messages from the switch reflecting call handling messages exchanged between theISDN switch and each of the agent stations. The messages are interpreted by the computer, which generates station status information and management information such as the number of calls handled, average holding time per call, etc. The computer may be connected simultaneously to several central offices via ISDN subscriber lines and generate management information for a group of geographically separated agents, such as home telemarketing agents operating out of their individual homes and connected to different central offices. Based on the generated status and management information, the computer performs an incoming call management function by selecting agents connected to different switches for handling incoming calls and transmitting to the ISDN switch appropriate messages for causing the switch to transfer incoming calls to the selected agents. Additionally, the computer performs an outgoing call management function by initiating outgoing calls and causing the switch to connect an answering party to an agent, selected by the computer on any of the switches.

Abstract: A co-variance microwave water cut monitor includes a test cell having a petroleum stream flowing through it while permitting the microwave energy to enter the test cell. A microwave source provides microwave energy to a circulator which in turn provides the microwave energy to an antenna. The antenna provides the petroleum stream=.in the test cell with the microwave energy and receives reflected microwave energy back from the stream. The reflected microwave.energy is provided by the antenna to the circulator which in turn provides the reflected microwave energy as test microwave energy. A detector assembly connected to the circulator detects the intensity of the test microwave energy and provides a corresponding intensity signal. Indicator apparatus connected to the circulator to the microwave source and to the detector assembly provides an indication of the water cut of the petroleum stream in accordance with the intensity signal and the phase difference between the source provided microwave energy and the test microwave energy.
