Title: Preparations pharmaceutiques pour pallier de facon ciblee la carence en oestrogenes du systeme nerveux central
Inventor: OETTEL MICHAEL
IPC: A61P5/24
Filed: 1999-02-10
Abstract: La présente invention concerne l'utilisation de stéroïdes sélectionnés pour la production de préparations pharmaceutiques destinées à pallier de façon ciblée la carence en oestrogènes du système nerveux central sans influer sur d'autres organes ou systèmes. Ces stéroïdes se caractérisent en ce que, contrairement aux oestrogènes naturels et synthétiques à action systémique, y compris le 17a-estradiol, ils présentent un effet de transcription sélectif, neurotrope semblable à celui des oestrogènes. Il a été constaté, de façon surprenante, que les stéroïdes sélectionnés présentent, lorsqu'ils sont utilisés selon l'invention, les caractéristiques suivantes: ils provoquent une influence sélective de la transcription de gènes dépendant des oestrogènes, dans le système nerveux central, ainsi que des modifications de paramètres physiologiques correspondants; ils présentent des effets de transcription spécifiques au système nerveux central dans des doses qui n'ont aucun effet biologique dans les tissus du système de reproduction; ils présentent des effets de transcription spécifiques au système nerveux central à des doses avec lesquelles ni le 17b-estradiol, ni le 17a-estradiol n'ont une efficacité; et ils n'influent pas sur la transcription de gènes dépendant des oestrogènes, dans le système nerveux central, dans une plus grande mesure que le 17b-estradiol formé de façon secondaire.

Title: High-pressure ball-poppet control valve
Inventor: WEILER CHARLES A JR
IPC: F15B13/04
Filed: 2000-11-08
Abstract: A high-pressure fluid control valve is disclosed for operating a fluid-actuated device. Preferably a ball-poppet and frusto-conical valve seat adapted for substantially line-type contact therebetween are provided with an upstream restricted flow area in order to substantially minimize sonic flow damage to the actual sealing surface of the valve seat.  Preferably, the ball-poppet is movable within a poppet guide that is allowed to float radially in order to allow the ball-poppet to be substantially self-centering with respect to the valve seat.  In addition, cross-over leakage is preferably negated by closing an exhaust ball-poppet just prior to opening a supply ball-poppet.

Patent CA-2337874-A1 (CA)
Inventor: ZHOU SHU-ANG
IPC: H01P3/08
Filed: 1999-07-16
Abstract: An inductor for microwave frequencies has a substantially planar structure and is constructed of a transmission line designed as a linear microstrip element made of a central line (5) comprising normal electrically conducting material, such as a suitable metal. The microstrip element has a width which is varied by making areas (7) at sides of the central line (5) superconducting. In changing the effective width of the microstrip the inductance thereof is changed accordingly. The areas at the sides of the microstrip element are located directly at the central, normal metal conductor. These areas have in the non-superconducting state some electrical conductivity which can be rather low but owing to the fact that they contact the normal central metal conductor only at a very narrow edge instead of contacting it at a large surface they do not significantly affect the transmission characteristics of the transmission path when the superconducting areas (7) are in their normal state.

Title: Side entry sub
Inventor: CADRIN DAVID
IPC: E21B17/02
Filed: 2001-03-02
Abstract: The invention provides for an improved method of removing debris from a producing oil, gas, or commercial water well without the necessity of using a service rig or retraction of the tubing string. In accordance with this method there is provided a side entry sub that is situated in the well casing string. The side entry sub has an access port with a hollow feed passageway permitting the introduction of coiled tubing into the main flow passage. The coiled tubing is passed down the main flow passage adjacent to the tubing string to the desired depth. Fluids are then introduced into the well through the coiled tubing. The fluids mix with the debris and the mixture is forced to flow out of the well using the tubing string or the main flow passage of the production casing. This flow of liquefied debris facilitates effective extraction of the debris from the well without the need of a servicing rig for production tubing retraction and intervention with specialized cleanout tools.

Inventor: WEBSTER ROBERT HOLDEN
IPC: B21D22/21
Filed: 2001-03-12
Abstract: An apparatus and method for deep drawing a heavy gage workpiece into a drawn part. A lower die section includes a die cavity therein and a base mounting surface thereon, and further includes a die radius defined between the base mounting surface and the die cavity. Riser blocks mount to the base mounting surface of the die for supporting the workpiece at a predetermined elevation above the base mounting surface of the die. A punch having an end face is capable of reciprocating past the riser blocks and into and out of the die cavity. The workpiece is located on the riser blocks over the die cavity. The punch is advanced from a retracted position into the die cavity, wherein the end face of the punch contacts the workpiece such that the punch and the riser blocks cooperate to pre-form the workpiece therebetween as the punch moves toward the die, but before the workpiece enters the die. Thus, the punch and riser blocks cooperate upon the workpiece to start metal working in areas of the workpiece that are typically prone to defects, in order to prevent such defects.
