Patent CA-2539244-C (CA)
Title: Perforation gun system producing self-closing perforation holes
Inventor: ROSPEK ROLF
IPC: E21B43/119
Filed: 2004-09-22
Granted: 2012-02-21
Abstract: The invention relates to a perforation gun comprising an external gun barrel (1) in the interior of which perforators (10) are located which can be ignited via a fuse (11) extending through the gun barrel (1) and which, after ignition, pierce the gun barrel (1) with perforation holes (13), whereby means are provided which automatically close the perforation holes (13). According to an embodiment of the invention, the means for automatically closing the perforation holes comprise cartridges including a swellable two-component foam. Said cartridges are located inside the gun barrel (1) and can be broken up by the ignited fuse (11), thereby allowing foam to escape from the cartridges, allowing it to swell and obliterate the perforation holes (13). If the means for automatically closing the perforation holes (13) comprise a sliding tube (4) that can be displaced after perforation by an adjusting device by at least the diameter of the perforation hole (13), the sliding tube (4) is located coaxially between the perforators (10) and the gun barrel (1).

Abstract: Pendant l'électroréparation de champs électriques de sol générés par deux électrodes (10, 12) situées dans ce sol, on utilise pour la décontamination des agents complexants, des réactifs de chimie et/ou des nutriants à travers le sol ou pour chauffer le sol. La commande des tensions et/ou des courant sur ou à travers les électrodes (10, 12) est utilisée pour empêcher des problèmes d'encrassement électrode, afin de réduire une consommation électrique inutile et/ou d'empêcher l'ébullition. Dans un aspect (réparation électrocinétique et chauffage électrique) le courant passant à travers deux électrodes sélectionnées (10, 12) est temporairement abaissé si on détecte un encrassement ou une ébullition à partir d'une augmentation de résistances électriques d'une électrode présente dans le sol. De préférence un effet des modifications de résistivité du sol sur la détection est éliminé via l'utilisation d'électrodes de détection (14a, 14b) dans le sol. Dans un autre aspect ((bio)barrière/protection électrocinétique) la tension ou le courant est adapté en fonction des changements de vitesse d'écoulement des eaux du sol mesurée, de sorte que ce procédé reste efficace avec une consommation électrique minimum. Dans un autre aspect encore pour (phytoréparation électrode cinétique) les inversions de polarité du courant sont synchronisées au moyen de mesures de courant cumulatives. Se fera le groupe

Title: Enhanced reverse buckling rupture disc
Inventor: MOZLEY ROBERT M
IPC: F16K17/16
Filed: 1999-03-15
Granted: 2010-03-09
Abstract: An improved reverse rupture disc for use as a safety pressure relief device is provided. The disc is defined by an annular flat flange region, a concave-convex disc dome region and a transition region that joins the disc-shaped flat flange region to the concave- convex disc dome region. One or more deformations may be formed at or near the apex of the disc dome region for weakening the disc to the point that incidental damage to the disc will not weaken the disc any further, thereby ensuring that the disc will reverse at a certain pressure, and no lower. The disc may also formed with one or more irregular transition regions at the base of the disc and a partial circular groove in the transition region. The irregular transition region of the disc cooperates with a shear enhancing means such as a protrusion or notch formed in a support ring or disc holder disposed downstream of the disc to sever the disc dome from the annular flat flange region along the groove in the transition region. A back pressure support means extends over the transition region and potentially over the dome region to prevent vacuum and forward to reverse cyclical pressures in the convex direction from damaging or destroying the disc. An ungrooved region of the transition region acts as a hinge holding the ruptured disc dome to the flat flange region after the disc has ruptured. The ruptured disc dome hangs over an arcuate projection formed in the support ring or disc holder, which helps to prevent the disc from fragmenting.

Abstract: Previous methods for culturing human embryonic stem cells have required either fibroblast feeder cells or a medium which has been exposed to fibroblast feeder cells in order to maintain the stem cells in an undifferentiated state.  It has now been found that if an antagonist of bone morphogenic protein is added to the medium in which the stem cells are cultured, together with fibroblast growth factor, the stem cells will remain undifferentiated indefinitely, even without feeder cells or conditioned medium.

Abstract: Reducing the digestion of digestible carbohydrates in a digestible carbohydrate-based material, and reducing the absorption of the digestion product(s) of digestible carbohydrates (that is, simple sugars) within the small intestine. The undigested digestible carbohydrate and the unabsorbed digestion products pass through the small intestines and into the colon, where they are fermented. In effect, the food materials made by practicing the present invention cause a controlled amount of digestible carbohydrate to by-pass the small intestine, resulting in the fermentation of digestible carbohydrates in the colon. The invention also provides for processing of a digestible carbohydrate-based ingredient with a non-digestible food film material, to form a reduced digestible carbohydrate food having a protective food film network, which can inhibit or prevent digestion of the digestible carbohydrate. The present invention also provides for processing of a digestible carbohydrate-based ingredient with a non-digestible food film material, to provide a resulting reduced digestible carbohydrate food containing a viscosity-building component that contributes to the formation of a viscous intestinal chyme that can inhibit or prevent digestion of the digestible carbohydrate and can inhibit adsorption of digestion products of digestible carbohydrates in the small intestine.

Abstract: An apparatus and method for using a counter-propagating signal method for locating events is disclosed. The apparatus and method uses a Mach Zehnder interferometer through which counter-propagating signals can be launched. If the sensing zone of the Mach Zehnder interferometer is disturbed, modified counter-propagating signals are produced and the time difference between receipt of those signals is used to determine the location of the event.  Polarisation controllers (43, 44) receive feedback signals so that the polarisation states of the counter-propagating signals can be controlled to match the amplitude and/or phase of the signals. Detectors are provided for detecting the modified signals.

Abstract: A method of determining the location and/or amplitude of a leakage signal from a network includes measuring at various times and locations leakage believed to be associated with the leakage signal and constructing a data base of leakages and associated locations. Leakage signal values are selected from the data base. Each of the selected leakage signal values is multiplied by a locus of points on which a leakage signal associated with that respective signal strength may be assumed to reside in order to develop a number of relationships among leakage signal strength, leakage and location. A first pair of these relationships among leakage signal strength, leakage and location is solved for a first locus of points common to the first pair. A second pair of these relationships among leakage signal strength, leakage and location is solved for a second locus of points common to the second pair. The first and second loci are projected onto a common surface, and an intersection of the thus-projected first and second loci on the common surface is determined.
