Title: Catalytic downhole reactor and steam generator
Inventor: GONDOUIN MICHEL
IPC: E21B34/00
Filed: 1991-03-19
Abstract: CATALYTIC DOWNHOLE REACTOR AND STEAM GENERATOR      ABSTRACT OF THE DISCLOSURE          A Downhole catalytic Methanator reactor assembly is hung within the cemented casing of a vertical well for the purpose of producing large volumes of high quality steam and oil soluble gases for injection into horizontal drainholes drilled into a deep Heavy Oil reservoir,in order to make the Heavy Oil more mobile.Steam is generated in part by the heat of chemical reactions taking place within the reactor assembly. The exothermic Methanation reaction takes place within a fixed bed of catalyst particles,at a temperature below 800 F,when a Syngas feed (H2,CO and/or CO2) comes in contact with a catalyst.Boiler feed water supplied to the reactor assembly from the surface is vaporized in boiler-type water tubes immersed in the catalytic bed,or by direct contact with the catalyst and with the hot gas phase flowing through the bed.The Syngas feed may be supplied to the reactor from the surface,or made directly by Partial Oxidation of Natural Gas in Oxygen within the downhole assembly.The reactor assembly may also be located within a cemented metal-lined cavity under-reamed below a cased access well. For operating each of the horizontal drainholes successively in the cyclic ("huff and puff") mode,a downhole valve section is included in the assembly.Multi-way downhole retrievable valves are used for this purpose. This apparatus presents the advantage of largely reducing the steam heat losses in surface lines and in well tubings.

Abstract: La présente invention concerne de nouvelles compositions stabilisées à base de polymère halogéné et plus spécifiquement de polymère chloré. Plus précisément, la présente invention consiste en des compositions stabilisées à base de polymère chloré, caractérisées en ce qu'elles contiennent: a) une quantité efficace de dawsonite et/ou d'hydrotalcite, b) une quantité efficace d'une huile polyorganosiloxanique .gamma.-hydroxy-alkylée, c) une quantité efficace d'un composé organique du zinc, et d) une quantité efficace d'un composé organique du calcium, du magnésium, du baryum ou de lanthanides. La présence de l'huile polyorganosiloxanique permet la diminution du taux d'huiles époxydées, tout en conservant aux compositions polymériques la stabilité thermique des compositions contenant un taux plus élevé de ces huiles époxydées. Elle permet aussi de renforcer la résistance aux chocs des objets conformés préparés à partir des compositions de l'invention.
Patent CA-2042253-A1 (CA)
Inventor: KLAPPERT WILLI
IPC: H01F27/24
Filed: 1991-05-09
Abstract: Groups of amorphous steel strips, cut to appropriate length from a composite strip, are stacked in longitudinally-staggered relationship to form packets. The groups are made up by a process that comprises a pre-spooling operation that results in the strips and groups in each packet adhering together, even though dry. The individual packets are fed successively into a belt nester that includes a rotatable arbor and wrapping means that wraps the packets in superposed relationship about the arbor as the arbor rotates, thereby building up a hollow core form. The above-described adhesive effect precludes the strips and groups from shifting longitudinally while the packets are being wrapped about the arbor.

Abstract: Power Supply Unit and Welding Equipment ABSTRACT OF THE DISCLOSURE    A power supply unit comprises three input terminals connected to a three-phase A.C. power supply, a phase control circuit controlling the firing of the three-phase A.C. for each phase, and a transformer comprising a single-phase iron core which is winded by first to third primary coils at the primary side and by a single-phase secondary coil at a secondary side and in which the first to third primary coils are connected to the three-phase A.C. power supply, and it outputs a single-phase A.C. having the frequency three times as that of the input current.          Therefore the problem of unbalance between three phases is solved and a small-sized and lightweight power supply unit can be obtained.  In addition, use of the power supply unit in a welding equipment allows to miniaturize the high efficiency welding equipment.

Filed: 1991-07-18
Abstract: Abstract of the Disclosure A cylindrical ferrule type optical fiber connector (20) includes an attenuator arrangement which includes an element (70) that is capable of movement during the assembly of the connector. The connector includes a cylindrically shaped sleeve (60) which has a longitudinally extending slot (61) formed through the wall thereof and which is adapted to receive a cylindrical plug (40) in each end thereof, each plug being spring-biased outwardly from a cap (45) and terminating an optical fiber (21). The attenuator element has a disc-shaped portion (74) which is disposed within the sleeve. A neck portion (76) which extends through the slot of the sleeve connects the disc-like portion to a supporting head portion (72) which engages an outer surface of the sleeve. As one plug is inserted into the sleeve, it engages the attenuator element and causes it to be moved along the slot in the sleeve.

Abstract: RESTRICTION-DEFICIENT MUTANT            Abstract The present invention relates to a mutant of Bacillus thuringiensis and/or B. cereus that has a partial deficiency of the restriction barriers inherent in the unmutated starting strain and that may therefore be transformed significantly better than the said non-mutated starting strain when vector DNA from a heterologous intermediate host that is naturally subject to restriction in B. thuringiensis and/or B. cereus is used. Special preference is given to the partially restriction-deficient mutant B. thuringiensis var. kurstaki HD1cryB Res9, which is obtainable by means of spontaneous mutation from the B.t. strain HD1cryB and can be obtained by means of enrichment methods known per se, The invention relates also to methods of preparing the said mutants that are based on the specific enrichment of spontaneous mutants and to methods of cloning genes or other DNA sequences using the said restriction-deficient mutants of Bacillus thuringiensis and/or Bacillus cereus.

Filed: 1991-10-08
Abstract: A  handle  is  provided  for  blades,   and particularly surgical blades, which allows simple insertion sequentially of a plurality of blades, and closure to a locked position of the blade, upon  insertion.   The  two  parts of  the  handle pivot  relative  to  one  another  in  the  same longitudinal  plane  around  a  pivot  positioned adjacent  the  blade  position.   This  allows  a relatively long handle portion for gripping the device for ejecting the blade, using the thumb or finger of the same hand for opening the holder for   ejection   single-handedly.    The  gripping portion of the handle has adjacent to the blade portion  thereof  a  boss  which  conforms  to  the opening in the blade tang.   Closure causes  the movable portion of the handle to cover the boss and the blade tang in a wedging action preventing movement of the blade relative to the handle in closed position.   When opening,  the user pushes the  movable portion  of  the  handle  open  while holding the blade and boss of the fixed handle portion facing downward so that the blade falls out  of  the  device,  without  any  touching  or movement of any kind, into a sharps collector.

Abstract: The present invention relates to a soil compactor equipped with at least one movable drum. To generate the desired compacting forces, the drum is equipped with two oppositely rotating exciter shafts which are matched to one another in their phase positions so that, if the exciter shafts are vertically superposed, their centrifugal forces act horizontally and in the same direction, thus causing a moment free horizontal force to be exerted on the drum axis, while, with the exciter shafts disposed in a juxtaposed arrangement, the centrifugal forces are amplified in the vertical direction and compensate one another in the horizontal direction.
