Abstract: Un connecteur rapide (10) a une paire de segments principaux (76 et 81), un segment en épaulement (163), un corps (72) pourvu d'une ouverture (156) et une patte (78). La patte (78) est constituée d'une paire d'éléments saillants (100) qui peuvent être pressés, au moins partiellement, l'un vers l'autre, ce qui provoque le mouvement de la paire de segments principaux (76 et 81) l'un vers l'autre. On réalise ainsi un connecteur pivotant ayant une longueur et un diamètre équivalents à ceux d'un dispositif de couplage fileté non pivotant classique. Le connecteur rapide (10) peut être libéré à la main ou par un outil pour jonc à ergots que l'on insère dans les trous (410).

Title: Downhole two-way check valve
Inventor: HUARD CHARLES
IPC: E21B34/08
Filed: 1996-07-19
Abstract: A check valve for use downhole in the production tubing of an oil and gas well. The check valve comprises a tubular valve body including a valve seat plate having an upper surface, a lower surface, an upflow orifice and a downfloworifice, a first valve ball contained within a ball cage which may seat on the upper surface of the valve seat plate closing the upflow orifice, a second valve ball contained within a downflow valve housing which may seat on the lower surface ofthe valve seat plate to close the downflow orifice. The second valve ball is biased in the closed position by a coil spring mounted within the downflow valve housing. Fluid pressure from below the check valve unseats the first valve ball allowing upward flow of fluid through the check valve and the production tubing. Fluid pressure from above the check valve will cause the first valve ball to seat and close while the second ball remains seated due to the coil spring. In that position, no downward flow of fluid is allowed. Additional pressure may be intentionally applied to partially compress the coil spring and unseat the second valve ball, allowing downward flow of fluid through the check valve and thus the production tubing. At even greater pressure, the coil spring is completely compressed, allowing the second valve ball to seat on a second valve seat opposite the valve seat plate. Again, no downward flow of fluid is permitted in this position.

Patent CA-2186546-A1 (CA)
Inventor: BETHEL ROBERT K
IPC: E21B43/1185
Filed: 1996-09-26
Abstract: A firing head for actuating an explosive charge in a perforating gun. A firing pin is positioned within the firing head housing to actuate a booster charge leading to the perforating gun. The firing pin can be actuated by mechanical techniques, by controlling the differential pressure between the housing pressure and the well pressure, and by controlling the absolute fluid pressure inside the housing. A release pin initially secures the firing pin, and the release pin can be mechanically actuated. The release pin is also releasably engaged with a differential piston that communicates with the well pressure through a port in the firing head housing. Increases in the housing fluid pressure moves the piston and attached release pin to release the firing pin into contact with the booster charge. Alternatively, the port can be plugged to permit absolute pressure actuation of the firing pin.

Patent CA-2195165-A1 (CA)
Inventor: RENDALL JOHN S
IPC: C10G9/00
Filed: 1997-01-15
Abstract: A process for the production of stable, pipelineable crude oil from heavy oils and/or bitumen that comprises feeding the heavy oils or bitumens either directly or after preheating into a fired heater.  The feed is heated and kept at an elevated temperature long enough to break the viscosity.  Alternatively, the feed is heated to a lesser temperature and transferred to a vessel for soaking over a longer time to break its viscosity. The heavy oil or bitumen feed may be prefractioned to removed lighter fractions prior to transferring the heavier fraction to the heater or heater/soaker which outputs visbroken products with lowered viscosity that are pipelineable crude oil.  For predistillation, the lighter fractions are recombined with the visbroken product for pipeline transport.

Title: Roll forming structural steel profiles with galvanised coating
Inventor: LANGFORD RODNEY MATTHEW
IPC: C25D5/26
Filed: 1996-07-09
Abstract: Structural steel profiles such as channels, having a material thickness greater than 2mm, are roll-formed to a preform profile with corners partial bent, in-line galvanized, and then further roll-formed to final shape. The preform profile has upwardly facing convex surfaces allowing rapid shedding of excess galvanising material. By preforming corners before galvanising, surface elongation in the galvanising layer is minimized and cracking eliminated. This is enhances by constant length bending of corners over preform and final roll-forming operations.
