Title: A method and a system for monitoring plurality of movable objects
Inventor: OLESEN LYKKE
IPC: G01S13/87
Filed: 1997-05-23
Abstract: A method and a system for monitoring a plurality of movable objects, wherein each of the objects is equipped with a transponder with which a stationary node is arranged to communicate. Each transponder is caused to reply to a unique signal from the node and each transponder that sends a response signal gives to the response signal a transponder identification addition. A node is caused to detect the speed and direction at which each transponder moves towards and away from the node. Movement of the transponder relative to the node is evaluated by node associated means on the basis of the speed and direction of the transponder. A register over those transponders with which the node shall communicate is set-up for each node. A plurality of separate nodes are provided and each node is provided with such a register. The nodes are arranged to communicate with one another, so as to enable a node to record in its monitoring register a transponder from another node.

Abstract: On décrit un système de traitement de déchets, notamment un système à creuset de fusion (14) et un système de dépollution de l'air (16). On achemine des fûts de déchets dangereux et/ou radioactifs, via un système d'alimentation en déchets, dans une chambre à plasma (20) dans laquelle on expose ces déchets à une chaleur provenant d'une torche à plasma (22). Une partie des déchets se volatilise et quitte la chambre à plasma (26) pour se diriger dans une seconde chambre de réaction (32) dans laquelle elle est brûlée afin de former un courant de gaz de combustion. Le système de dépollution de l'air (16) traite ce courant de gaz de combustion par refroidissement rapide, filtrage et lavage, afin de produire un courant de gaz propre convenant à une réinsertion dans l'atmosphère. On peut recycler les gaz de dégagement dans le système de traitement des déchets, si nécessaire. Les déchets restant dans la chambre à plasma entrent en fusion et tombent sur des surfaces de traitement en pente, à l'intérieur d'un creuset situé sous la torche à plasma. Le creuset comporte des électrodes de terre conçues pour établir un contact électrique avec les déchets contenus dans le creuset, de façon que ces déchets fondus et tombés dans le creuset puissent être ultérieurement chauffés par la torche à plasma. Lorsque l'on chauffe les déchets en fusion à l'intérieur du creuset, celui-ci est statique, permettant aux déchets en fusion de se séparer en une première fraction métallique présentant une gravité spécifique élevée, et en une seconde fraction de scories présentant une gravité spécifique relativement moindre. Après traitement suffisant des déchets en fusion, on abaisse le creuset à partir de la chambre à plasma, puis on le bascule dans une première direction afin de verser la fraction de scories, et on le bascule ensuite dans une autre direction afin de verser la fraction métallique, à partir d'un déversoir d'écoulement inférieur formé dans le creuset. Ce creuset comporte une seconde électrode de terre placée de manière stratégique près du déversoir, afin que les déchets restent en fusion au moment où ils s'écoulent le long d'un trajet situé sous le déversoir d'écoulement inférieur.

Filed: 1997-08-29
Abstract: L'invention concerne un procédé permettant de traiter les consignations d'événements dans un système de base de données de services. La base de données contient des tables de mesure (MT) constituées de rangées consécutives (Ri). Pour que l'utilisation des compteurs d'événements dans les rangées de la table de mesure soit efficace, lesdits compteurs ont été copiés et, dans chaque intervalle d'enregistrement, les valeurs des compteurs d'un certain groupe de compteurs d'une rangée sont incrémentées, et les valeurs des compteurs d'un autre groupe de compteurs de la même rangée sont enregistrées en fonction d'un principe de rotation prédéfini. L'enregistrement et la remise à zéro des valeurs des compteurs se font durant l'intervalle d'enregistrement, un seul objet à la fois, et le premier traitement de chaque groupe de compteurs après l'activation du groupe de mesure pour chaque objet du groupe de mesure bloque obligatoirement l'enregistrement du groupe de compteurs, mais autorise la remise à zéro du groupe de compteurs.

Title: Dendritic cells produced in serum-free culture
Inventor: VAN EPPS DENNIS E
IPC: A61K38/00
Filed: 1997-08-13
Abstract: A method for producing human dendritic cells (DC) for therapeutic purposes using serum-free, animal protein-free medium. The method involves culturing mononuclear cells from peripheral or umbilical cord blood or bone marrow of an individual human donor in a culture container having at least one inner surface of polystyrene in the above described medium containing at least one hematopoietic growth factor, and maintaining the culture to produce a culture enriched for DC. The DC enrichment is evidenced by at least about 10% of the total cells in the culture exhibiting DC processes, or at least 2.5 % of the total cells expressing at least one DC antigen such as CD80, CD86, or CD1a.  The culture method is preferably carried out in a gas-permeable container in a closed fluid path system. The DC so produced can be pulsed with an antigen such as a viral, bacterial, tumor, or cell surface antigen, and the resulting primed dendritic cells can be co-cultured with T cells to produce antigen-specific human T-cells for therapeutic use. Useful for treatment of viral or bacterial infections, useful as a cancer vaccine, useful to induce tolerance when transplant of allo- or xeno-graft cells or organ is intended.

Patent CA-2295566-A1 (CA)
Inventor: HARRIS ANNA JANE
IPC: B41M1/12
Filed: 1997-07-11
Abstract: A screen printing stencil is produced chemically by application of a chemical agent (4) to a carrier (2) having an image-receiving layer (1). The chemical agent (4) is applied dropwise using a computer-controlled ink-jet printer. The carrier is then brought into contact with a stencil-forming agent (6) on a screen printing mesh (5), whereby the chemical agent reacts with the stencil-forming agent to harden the stencil in areas which remain upon subsequent wash-out. The stencil so produced can be used for screen printing in the usual way.  In a variant, the chemical agent reacts with the carrier and excess chemical agent remains to react with the stencil-forming agent. A part of the carrier is thereby incorporated into the stencil improving its profile. The method avoids the use of safe light and actinic radiation.
