Abstract: L'invention concerne une machine de découpage à jet de fluide (10) équipée d'un dispositif d'élimination des particules abrasives, et un procédé correspondant. Selon une variante, la machine (10) comporte une buse (22), et un ensemble support (21) fixé à la buse (22) qui permet de déplacer ladite buse le long d'un trajet de découpe. Une source de fluide haute pression (24) et une source de particules abrasives (26) sont couplées à la buse (22), de manière à produire un jet de fluide abrasif (28) et une pluralité de particules abrasives permettant de découper une pièce à travailler. Le dispositif d'élimination des particules abrasives (40), dont est aussi équipée la machine (10), comprend un réservoir (42) aligné avec la buse (22), un récipient de décantation (46), et un mécanisme de transfert de fluide (44) acheminant le fluide du réservoir (42) au récipient de décantation (46). Le réservoir (42) comporte au moins un compartiment (56) conçu pour recevoir le fluide et les particules abrasives du jet de fluide (25), au moins le long d'une partie du trajet de découpe. Par ailleurs, ce compartiment (56) est conçu pour contrôler son flux de fluide interne, si bien que le jet de fluide met en suspension au moins une partie substantielle des particules abrasives dans le compartiment (56), et il maintient la suspension, sans agitation mécanique supplémentaire. Le mécanisme de transfert de fluide (44) peut comporter un conduit dont une première extrémité communique avec le compartiment pour l'écoulement de fluide, et dont une seconde extrémité à l'extérieur du compartiment (56) communique avec le récipient de décantation (46) pour l'écoulement de fluide. En fonctionnement, une partie du fluide du compartiment (56) renfermant des particules abrasives en suspension est transférée au récipient de décantation (46) via le conduit. Les particules abrasives de la partie transférée se décantent dans une zone inférieure du récipient de décantation (46), tandis qu'un fluide clarifié est évacué dudit récipient (46).

Filed: 1999-02-05
Granted: 2009-10-20
Abstract: The present invention is directed toward vector stage replication-defective flaviviruses that are replication-defective in mosquisto vectors that transmit them to human. Such mutant flaviviruses may be useful as vaccines. The replication-defective flaviviruses of the present invention demonstrate a limited ability to replicate in the vector organisms that transmit flaviviruses from one host to another. More specifically, the present invention is directed toward the construction and propagation of flaviviruses that possess 3'-noncoding regions altered in such a way as to prevent or severely limit viral reproduction in a vector organism. In one embodiment of the present invention, a replication-defective dengue virus that is replication-defective in arthropods is contemplated for use as a vaccine. In another embodiment, a replication-defective dengue virus that is replication-defective in mosquitos is contemplated for use as a vaccine. The present invention also contemplates methods of producing such mutant flaviviruses for use as vaccines as well as methods that induce a protective immunity against flavivirus infection or disease in an immunized subject.

Title: Hydrocarbon reservoir testing
Inventor: ROBINSON JAMES
IPC: G06T17/20
Filed: 1999-12-15
Granted: 2012-03-27
Abstract: A reservoir in a payrock (2) is analysed using finite element simulation. A  reservoir engineer selects an appropriate model from a set of template models, each comprising a set of polygons (51) in plan and layers (53) in elevation. The polygons are defined in objects instantiated from classes by control points and the layers as depth values of control points. A pattern object sweeps rotationally about a wellbore in a wellbore polygon to define a pattern of elements, fewer in number with distance from the wellbore. A polygon object also sweeps linearly from a generator line in the direction of a base line. The generator and a base lines correspond to polygon boundaries.  Finite element simulation is performed with the model so derived.

Granted: 2009-11-03
Abstract: Method is disclosed of estimating a property of a hydrocarbon-bearing formation penetrated by at least one injection (A, B, C, D) well through which fluid is injected into the formation and penetrated by at least one production well (E) through which fluid is produced from the formation. The injection rates of fluid through the injection wells are periodically varied and measured at substantially regular time intervals and measurements are also made of the production rate of fluid produced through the production well. A series of production well response delays are selected. A set of correlation coefficients between the injection rate for each injection well and the production rate as a function of response delay are determined. From each set of correlation coefficients, a time lag, corresponding to the maximum correlation coefficient is determined.  The time lag is then used to characterize a formation property, such as channel volume, permeability, or transmissibility.

Abstract: A system for locating an agricultural vehicle in a field using two position sensors. A first position sensor is a GPS sensor using satellite signals to locate the vehicle. The second position sensor is a crop edge sensor for locating the vehicle relative to a crop being harvested. A controller receives the first and second position signals and calculates the position of the vehicle based on these two position signals. Both position signals contain signal quality information that is evaluated by the controller and weights the position calculation accordingly. The system can be used in conjunction with a steering controller to automatically guide the vehicle through a field.
