Title: Rubber laminated bearing-seal for a shaft penetrating a pressure vessel
Inventor: HINKS WILLIAM L
IPC: F16J15/50
Filed: 2000-03-13
Granted: 2005-01-04
Abstract: At least one rubber laminated bearing-seal, consisting of multiple flat or curved alternate laminations of metal and rubber bonded together and having an aperture, is seated in a complementally-configured apertured receptacle in the wall of a pressure vessel and supports and seals a shaft that penetrates said apertures and extends through the wall. Shear strains in the rubber laminations permit the shaft to carry limited movements through the wall while the laminations seal against any flow of the liquid or gaseous medium on one side toward the other and withstand the resulting thrust caused by large pressure differences. The torque reaction of this bearing-seal is essentially proportional to rotation angle. A potential use is in the intense undersea hydrostatic pressure environment at great depths, carrying limited motion through the hull of a submersible craft. Safety backup against seal failure is provided.

Abstract: L'invention se rapporte à une nouvelle composition comportant des molécules polymères organiques possédant des liaisons doubles carbone-carbone et destinée à la suppression de l'hydrogène de l'atmosphère d'espaces fermés. Les molécules polymères organiques contenant des liaisons doubles carbone-carbone au sein de leur structure sont de préférence du polybutadiène, du polyisoprène et des dérivés de ces composés. Ces molécules sont intimement mélangées à un composition insoluble à effet de catalyseur, composée d'un catalyseur d'hydrogénation et d'un support de catalyseur, de préférence du palladium supporté sur carbone. Lesdites molécules constituent une composition de suppression de l'hydrogène destinée à supprimer l'hydrogène dans des espaces fermés même en présence de contaminants tels que des gaz atmosphériques communs, de la vapeur d'eau, du dioxyde de carbone, de l'ammoniac, des dispersions d'huile et de l'eau.

Title: Field upgrading of heavy oil and bitumen
Inventor: ABDEL-HALIM TAYSEER
IPC: E21B43/24
Filed: 2001-01-30
Granted: 2010-03-23
Abstract: A process and system which integrates on-site heavy oil or bitumen upgrading and energy recovery for steam production with steam-assisted gravity drainage (SAGD) production of the heavy oil or bitumen. The heavy oil or bitumen produced by SAGD is flashed to remove the gas oil fraction, and the residue is solvent deasphalted to obtain deasphalted oil, which is mixed with the gas oil fraction to form a pumpable synthetic crude. The synthetic crude has an improvement of 4-5 degrees of API and lower in sulfur, nitrogen and metal compounds. The synthetic crude is not only more valuable than the heavy oil or bitumen, but also has substantial economic advantage of reducing the diluent requirement since it has lower viscosity than the heavy oil or bitumen. The asphaltenes, following an optional pelletizing and/or slurrying step, are used as a fuel for combustion in boilers near the steam injection wells for injection into the heavy oil or bitumen reservoir. This eliminates the need for natural gas or other fuel to produce steam at reservoir location and thus improves the economics of the heavy oil or bitumen production substantially. Alternatively, the asphaltenes are used as a feedstock for gasification to produce injection steam, synthesis gas. The CO2 could be used as additive with injection steam to enhance the performance of SAGD and the hydrogen could be exported to nearby processing facility. The invention upgrades the heavy oil or bitumen to a synthetic crude of improved value that can be pipelined with reduced amount of diluent, while at the same time using the asphaltene fraction of the residue for combustion to fulfill the energy requirements for generating injection steam for SAGD.

Abstract: L'invention porte sur un jeu d'empilage comprenant une pluralité de dés pouvant s'empiler par couche et un manchon allongé comportant quatre côtés plans formant un intérieur de retenue des dés du jeu, par couche. Des ouvertures sont ménagées dans les côtés et coïncident avec les couches de dés, et sont dimensionnées de façon à y faire passer les dés. Ces dés ont une forme cuboïde, comportent des signes de couleur sur leurs faces, et sont insérés à l'intérieur du manchon, par couche de quatre. Ce jeu d'empilage consiste à attribuer à chaque joueur un signe différent, chaque joueur éjectant ensuite, tour à tour, l'un des dés de l'intérieur du manchon en appuyant un dé du jeu déjà éjecté par l'une des ouvertures contre un dé opposé à celui devant être éjecté. En général, chaque joueur note le signe de la face supérieure du dé précédemment éjecté, et appuie ensuite ce dé contre le signe d'un dé du manchon correspondant au signe noté. Toutefois, si le signe de la face supérieure du dé éjecté par un joueur correspond au signe attribué au joueur, le joueur rejoue et a le droit d'appuyer le dé éjecté contre n'importe quel dé se trouvant dans le manchon. Les joueurs reprennent leur tour en éjectant les pièces jusqu'à ce que tous les signes de couleur adjacents à l'un des côtés correspondent aux signes qui leur ont été attribués.
