Patent CA-2485210-C (CA)
Inventor: STREATER JAMES R
IPC: E21B23/08

Granted: 2007-12-18
Abstract: A packer retriever (100) having a grapple body (127) rotatably and slideably coupled to a mandrel (102) directly attached to a milling tool (140) can engage a packer (or extension thereof) (142) having a substantially smooth I.D. in a wellbore while the packer is milled. The mandrel rotates in a central opening through the grapple body (127). The grapple body does not rotate when released from teeth(134) of a nut(112) on the mandrel and can remain engaged to the packer ( or the extension) as milling proceeds. The mandrel includes a specially designed shoulder(116) and the grapple body includes a specially designed bearing (108), both casehardened, which allow the mandrel to rotate constantly while reducing die effects of wear. The packer retriever remains in the engaged position to prevent the packer from falling if it breaks loose while milling. The packer retriever can transfer torque to the packer and can be engaged and released multiple times.

Abstract: The present invention allows the usability of a write-once recording medium to be enhanced. The write-once recording medium is provided with an ordinary recording/reproduction area, an alternate area, a first alternate-address management information area (DMA) and a second alternate-address management information area (TDMA) In addition, written/unwritten state indication information (a space bitmap) is also recorded. The second alternate-address management information area is an area allowing alternate-address management information recorded therein to be renewed by adding alternate-address management information thereto. In addition, the written/unwritten state indication information indicates whether or not data has been recorded in each data unit (cluster) on the recording medium. Thus, it is possible to correctly execute management of defects and properly implement renewal of data in the write-once recording medium.

Abstract: L'invention se rapporte à un réacteur conçu pour l'oxydation d'un précurseur en un acide carboxylique aromatique ou en ester d'un tel acide dans un mélange réactionnel en phase liquide. Ce réacteur (1) comporte une cuve oblongue, sensiblement verticale en cours d'utilisation, ayant un élément de mélange supérieur (5) et un élément de mélange inférieur (3), et elle se caractérise en ce que l'élément de mélange supérieur (5) est une pompe à palettes axiale et l'élément de mélange inférieur (3) est une pompe à palettes radiale. L'invention se rapporte également à un procédé de production d'un acide carboxylique ou d'un ester d'un tel acide dans un réacteur tel que celui décrit ci-dessus. En cours d'utilisation, la structure des éléments de mélange conduit à trois zones de mélange fortement turbulentes. Dans un mode de réalisation préféré du procédé de la présente invention, un oxydant, provenant d'un orifice d'entrée, et un solvant, un précurseur et un catalyseur, sont introduits directement dans une zone de mélange. Les zones de mélange fortement turbulentes permettent d'obtenir un transfert de masse rapide, ce qui supprime la formation de produits dérivés non désirés, colorés, et permet un encrassement réduit du réacteur.

Title: Impact tool
Inventor: OTTESTAD JACK B
IPC: B25D9/20
Filed: 2004-12-16
Granted: 2012-03-13
Abstract: An impact tool (20) has a slidable hammer (82) that is driven by hydraulic oil under pressure inside a chamber (26,89). The hydraulic oil is pressurized by a piston (110,280) driven by compressed gas on the opposite side of the piston (110,282) from the hydraulic oil. The gas in the gas chamber (62,72,251A,294) is compressed by the piston (110,282) on an initial stroke, and has a large annular chamber (62,294) holding the gas so that higher average gas pressure can be attained during a power stroke of the piston (110,282). As the piston (110,282) is moved to compress the gas, the piston lifts a valve (116,256) that opens a passage (134,135,136,262,264,265) for the hydraulic oil moved by the piston (110,280) to act on a hammer (82) to impact a breaking tool (98).  The piston (110,280) is a two part (112,114,284,290) piston that serves to lower the inertia during the final closing of the valve (116,256), and thereby reduces impact loads on the valve (116,256) as it is closed. The valve (116,256) also is controlled as to its stroke for efficient operation.

Abstract: Rebord d'évier pouvant être facilement adapté aux méthodes conventionnelles d'encastrage, de sous-montage et de montage affleuré. En incorporant une bride périphérique de montage plus épaisse et plus large, s'étendant vers l'extérieur, un rebord d'évier à montage triple est obtenu. Présentant une surface plane à la fois sur la surface supérieure et la surface inférieure de la bride périphérique de montage s'étendant vers l'extérieur, le rebord peut être monté en tant qu'évie à montage encastré ou à sous-montage. Des rebords sensiblement carrés (dont l'angle se situe entre 85 et 91 degrés, de préférence entre 80 et 91 degrés) sont formés en soudant des pièces séparées pour former l'évier. Ces bords extérieurs carrés, contrairement aux bords roulés ou aux bords biseautés, produisant un rebord à montage affleuré véritable, repoussant ainsi les limites des éviers selon l'état antérieur de la technique. L'épaisseur et la largeur supplémentaires de la bride périphérique de montage s'étendant vers l'extérieur permettent un support adéquat de l'éviers lorsqu'il est monté en affleurement.
