Patent CA-2361874-C (CA)
Inventor: OHMER HERVE
IPC: E21B7/06
Filed: 2001-11-13
Granted: 2005-05-24
Abstract: A whipstock-less milling apparatus and method for use in a wellbore having a first structure (e.g., a tubular structure such as a casing, liner, or other tubular structure) includes a support element, at least one mill supported by the support element, and a deflection apparatus to deflect the at least one mill to engage the first structure to form an opening in the first structure. In one example, the opening is a window cut through a casing or liner to allow a change in the trajectory of the wellbore or to form a lateral branch from the wellbore in a multilateral well. In another example, one or more axial slots can be formed in the casing or liner to enable propagation of electromagnetic (EM) waves through the slotted casing or liner to measure characteristics of the surrounding formation. In yet a further example, sensors, gauges, and other measurement devices may be placed in a window or outside pocket formed by the whipstock-less milling apparatus. Deflection of the at least one mill is controlled by a deflecting actuator unit activated in response to rotation of a rotatable shaft. The rotation of the rotatable shaft also causes rotation of the at least one mill. When the at least one mill is deflected to engage the first structure, it cuts the opening into the first structure. While the at least one mill is still rotating, longitudinal displacement of the at least one mill is controlled by a feed actuator unit to form an opening having a desired length.

Abstract: An apparatus for rigless subterranean well completion, re-completion, servicing or workover includes at least two substantially vertically oriented double acting prime movers incorporated into a spool for pressure containment, which is mounted to the top of a wellhead. The spool further includes a Bowen union mounted to a top thereof for sealingly connecting an annular adapter, which provides a seal between the.well bore and a tubular that is inserted under the well fluid pressure into the well by the prime movers. The spool may further include a mechanism for securing a hydraulic crane that can be temporarily mounted to the top of the spool to hoist equipment and tools above the wellhead when the prime movers are used to support heavy workloads induced by well fluid pressure or the weight of a tubing string. The apparatus can be used in various operations for well completion, re-completion, servicing or workover without the necessity of using a servicing rig. Consequently, the cost of those operations is significantly reduced.

Title: Internal sliding closure lock
Inventor: PLETT BENJAMIN
IPC: E05C17/64
Filed: 2002-01-22
Granted: 2006-07-25
Abstract: A sliding closure (door or window) lock has a rectangular tubular enclosure which has a plunger mounted on am interior camshaft. Rotation of the camshaft by a handle or lever moves the plunger between an extended position, where its serrated outer end frictionally engages an interior surface of the channel for the closure, and a retracted position without frictional engagement.      The enclosure has an adjacent apertured flange to secure it to an inner surface of the closure. The device may be made of two plates in which case one plate forms two walls of the enclosure and the flange, and the other the other two walls and a thickness of the flange. A stub flange also with apertures on remote corner of the enclosure allows the plates to be fastened at the other side of the enclosure.

Abstract: The invention refers to a device for measurement of the thickness of a first layer, comprising one or more sublayers, on a second layer of a metal sheet by X-ray fluorescence analysis comprising means for generating and directing a beam of polychromatic primary X-rays, said beam being able to penetrate into the first and second layers for converting primary X-rays into chemical element specific fluorescent X-rays by means of absorption of primary X-rays and re-emission of fluorescent X-rays by the chemical element, and further comprising means for detecting element specific fluorescent X-rays and determining an intensity thereof. The means for detection have been placed a t an angle with respect to the primary beam of X-rays in dependence of the chemical element from which the fluorescent X-rays are to be detected. Herewith an improvement of the efficiency of detection is achieved, and the measurement time is reduced accordingly. Hence, a device is provided with which alloys with a low concentration of fluorescent elements can now be analysed, for determining the thickness of a cladding.

Abstract: La présente invention concerne un procédé destiné au revêtement avec un matériau d'étanchéité liquide (61) de la périphérie du passage de gaz et du passage d'eau d'un séparateur de pile à combustible (57), ledit procédé comprenant les étapes suivantes: déplacement d'une section d'application (33) mise en place dans un dispositif d'application de revêtement de matériau d'étanchéité (24), pour qu'elle se trouve plus proche du séparateur que d'autres parties différentes de la partie de début d'application de revêtement; et déplacement de la section d'application à une vitesse de déplacement horizontal inférieur à celle d'autres parties différentes de la partie de début d'application de revêtement dans une partie de début d'application de revêtement de matériau d'étanchéité (63). Le déplacement de la section d'application pour qu'elle se trouve plus proche du séparateur provoque l'augmentation de la force de compression avec laquelle le matériau d'étanchéité expulsé par la section d'application est appuyé contre le séparateur, ce qui permet d'obtenir un contact plus intime du matériau d'étanchéité avec le séparateur, et d'éviter ainsi le relèvement de l'extrémité frontale du matériau d'étanchéité. De plus, la diminution de la vitesse de déplacement horizontal de la section d'application garantit l'application d'un revêtement de matériau d'étanchéité ayant une épaisseur plus uniforme.

Abstract: Platinum-free chelate catalyst materials for the selective reduction of oxygen have application in hydrogen and methanol fuel cells. Conventional catalyst material comprises an unsupported transition metal and a nitrogen- and a carbon-donor, which are polymerized to give a carbon matrix under pyrolytic conditions, in which the unsupported transition metal, functioning as electron donor and a nitrogen-coordinated transition metal chelate are bonded. The achievable porosity, catalytic activity, and stability are, however, not adequate for commercial applications. Said chelate catalyst material comprises, in addition to the at least one unsupported transition metal, a nitrogen-containing organo-metallic transition complex, with a further transition metal different from the said transition metal and a chalcogenic component. The advantages of various transition metals and the chalcogens as electrically conducting bridge-formers can thus be combined. The unsupported transition metal in the form of a salt serves as filler during the formation of the carbon matrix, such that the above is embodied as an ultra-highly-porous material due to a foaming effect on thermal decomposition of said salt. Said chelate-catalyst material is particularly suitable for application in commercial industry, for example the auto-industry as a result of the high activity, stability and low cost thereof.

Abstract: A thrust bearing assembly is described that includes a self-aligning thrust bearing used in fluid thrust assemblies where the thrust may become unevenly distributed, e.g. in a water jet propulsion unit. The thrust bearing is designed to be lubricated by water and to be self-aligning against uneven thrust forces applied to it. The self-alignment is achieved by the design of the bearing, which is in the form of an annular multi-layer plate. The bearing plate comprises a metallic central core layer, an interface layer of marine bearing material on one side of the core and a flexible backing layer on the other side of the core. The backing layer supports the thrust flange against a support face and is formed of a high resilience polymer material capable of being deformed under thrust action sufficiently to align the thrust bearing to correct for uneven thrust.
