Title: Outil de maintien de la penetration dans un puits de forage
Inventor: LABONTE RAYMOND C
IPC: E21B19/08
Filed: 1994-10-12
Granted: 2001-04-24
Abstract: Outil adapté pour se placer dans le train de tiges d'un puits de forage et destiné à maintenir la pénétration d'un trépan fixé au train de tiges lorsque ce dernier se coince au cours des opérations de forage. L'outil comporte des éléments externe (20) et interne (22) télescopiques délimitant entre eux une chambre annulaire (64) renfermant une pluralité de ressorts (84) adaptés pour soumettre l'outil à une contraction appropriée lorsque le trépan subit une charge de compression axiale prédéterminée appliquée par l'intermédiaire de l'outil. L'outil comporte également des cannelures (81, 83) adaptées pour s'emboîter les unes dans les autres et formées sur les éléments externe et interne (20, 22) de manière qu'elles s'opposent à toute rotation de ces éléments l'un par rapport à l'autre. Par ailleurs, la chambre (64) est remplie d'un liquide hydraulique sous une pression égale à la pression hydrostatique régnant au voisinage de l'outil dans le puits de forage, ledit liquide étant mis sous pression par un piston flottant (92) monté mobile à l'intérieur de la chambre (64). Lors de l'exploitation, lesdits éléments de l'outil s'emboîtent l'un dans l'autre lorsqu'une charge de compression axiale est appliquée par l'intermédiaire de l'outil au cours des opérations de forage. Au cas où la charge de compression axiale diminuerait à cause d'un coincement du train de tiges, les ressorts provoquent le déboîtement des éléments de l'outil, ce qui entretient l'effort subi par le trépan et conserve le degré de pénétration de ce dernier dans le puits de forage.

Title: Circularly magnetized non-contact torque sensor and method for measuring torque using same
Inventor: GARSHELIS IVAN J
IPC: H01L41/12
Filed: 1995-06-02
Granted: 2000-10-24
Abstract: A torque sensor (2) comprises a magnetoelastically active element (4), and a magnetic sensor (6) responsive to the field of the magnetoelastically active portion. The magnetoelastically active portion comprises a ring of material (4) endowed with an effective uniaxial magnetic anisotropy such that the circumferential direction is the easy axis, and magnetically polarized in a substantially circumferential direction. The ring (4) is attached to the torqued member (8), such as a rotating shaft, so that application of a torque to the shaft is transmitted to the ring. A magnetic field vector sensor (6) is mounted in a fixed position relative to the ring (4) and oriented so that it responds maximally only to the field due to the axial magnetization components of the ring (4). The output of the sensor (6) is thus proportional to the change in orientation of the magnetization resulting from torque applied to the shaft (8) and transmitted to the ring (4). The magnetoelastically active portion (4) may include two or more axially distinct, magnetically contiguous, oppositely polarized circumferential regions (104, 105).

Title: Cleavage of 5.alpha.-reductase mrna
Inventor: SCANLON KEVIN J
IPC: A61K38/00
Filed: 1995-07-12
Granted: 1999-09-21
Abstract: The steroid enzyme 5.alpha.-reductase is responsible for the conversion of testosterone to the more-potent androgen dihydrotestosterone (DHT). The catalytic cleavage of nucleic acid encoding 5.alpha.-reductase by a ribozyme which selectively recognizes such nucleic acid reduces the level of expression of 5.alpha.-reductase by mammalian cells including human cells treated with such ribozyme. The reduction of nucleic acid (e.g. mRNA) levels leads to a corresponding reduction of enzyme levels and dihydrotestosterone levels in surrounding tissues, thus providing a therapeutic effect. The transformation of 5.alpha.-reductase producing cells with an expression vector containing a structural gene for a ribozyme is shown to decrease 5.alpha.-reductase expression. Pharmaceutical compositions and methods useful for topically administering effective amounts of such a ribozyme to hair follicle cells also are exemplified.

IPC: F04B47/00
Filed: 1997-04-04
Granted: 2000-08-01
Abstract: A downhole sucker rod pump especially well adapted for use in pumping thick oils and oils containing particles of sand or rock includes helical grooves or apertures for producing an intermittent unidirectional rotation of the plunger without appreciably restricting the flow of oil through the pump. This rotation distributes wear more uniformly around the plunger. In a first embodiment, helical apertures are provided in the cage portion at the upper end of the plunger. Because of their large axial extent, these apertures collectively provide an outlet of large area for the oil, and thus restrict the flow only slightly. Because of their inclination these apertures produce a torque on the cage and plunger. In a second embodiment, a second plunger is attached to the upper end of the cage. The second plunger includes helical grooves in its cylindrical outer surface. The lower portion of the cage is provided with apertures that permit the oil to flow from the interior of the cage into a space between the cage and the pump barrel, this space being closed at its upper end by the second plunger. To continue its upward movement, the oil must flow through the helical grooves of the second plunger, thereby imparting a torque to the cage. As in the first embodiment, a swivel connection is provided to permit rotation of the cage and plunger with respect to the pull rod.

Abstract: Le processus de métastase de tumeurs malignes peut être inhibé par l'administration au patient qui en a besoin d'une quantité suffisante de lactose pour bloquer les lectines cruciales de l'organe atteint, de manière à ce que les cellules tumorales ne puissent s'ancrer dans d'autres parties du corps. Le lactose peut être administré seul ou en association avec des médicaments cytotoxiques. Il est préférable que le lactose soit conjugué avec des substances cytotoxiques de manière à traiter la tumeur primaire et de prévenir simultanément la métastase. En outre, lorsqu'un médicament cytotoxique est conjugué à du lactose, il reste à proximité de la tumeur grâce aux récepteurs de cette dernière qui lient le lactose (et donc, l'agent cytotoxique qui y est associé) aux cellules tumorales. Lorsque l'on utilise un conjugué de lactose et d'agent cytotoxique, une dose suffit généralement à détruire les sites récepteurs de la tumeur et à prévenir la métastase de celle-ci tout en la traitant.

Title: System for maintaining engine oil at an optimum temperature
Inventor: HOLLIS THOMAS J
IPC: F01M5/00
Filed: 1996-02-02
Granted: 2007-06-12
Abstract: A temperature control system in a liquid cooled internal combustion engine equipped with a radiator controls the state of a flow control valve for controlling flow of a temperature control fluid through a passageway in the engine. Sensors detect an engine condition temperature, such as engine oil temperature. The sensors preferably also detect the temperature of the temperature control fluid and the temperature of the ambient air. An engine computer receives signals from the sensors and compares the signals to one or more predetermined values. In one embodiment, the engine computer compares the engine oil temperature signal to a predetermined value to control actuation of the valve. In another embodiment, the engine computer adjusts a predetermined temperature control fluid temperature value based on the comparison of the engine oil temperature signal to the predetermined engine oil temperature value. The engine computer then compares the temperature control fluid temperature, signal to the adjusted temperature control fluid temperature. The engine computer actuates the flow control valve based on the comparison of the temperature control fluid temperature signal to the adjusted temperature control fluid temperature. The predetermined engine oil temperature value and predetermined temperature control fluid temperature value preferably vary with ambient air temperature.
