IPC: E04C2/42
Filed: 1996-03-18
Abstract: L'invention concerne un treillis en fil métallique plus solide et présentant une plus grande souplesse d'utilisation que les treillis métalliques réalisés avec du fil métallique rond. Pour ce faire, ce treillis est réalisé avec des tiges métalliques (1, 2) ayant chacune au moins une face plane pour venir en contact d'aboutement avec les faces planes d'autres tiges métalliques (1, 2) dans le treillis, de manière à permettre un contact entre les tiges métalliques (1, 2) sur une surface donnée sur laquelle lesdites tiges métalliques (1, 2) sont fixées ensemble. Les tiges métalliques (1, 2) peuvent être rectangulaires en contact face à face, bord à face ou bord à bord. Le treillis métallique peut être utilisé dans des panneaux, par exemple pour réaliser une barrière ou il peut être plié pour former des conteneurs, des palettes, des plateaux ou encore il peut être posé à plat pour réaliser un plancher ou une passerelle.

Abstract: A static electricity dissipation garment where the body of the garment is constructed of fabric within which is woven strands of carbon.  The body will be constructed as a smock or as a pant suit.  The pant suit garment includes a pair of side seams located between the torso section of the garment and down each leg section of the garment.  The smock includes a similar pair of side seams in the torso section.   A first embodiment of the garment includes sleeve seams that extend along the entire length of each sleeve of the garment and then along the connection of the sleeve to the upper part of the torso section and then along the collar of the garment.  Within each of these seams, along the entire length of the seam, is included an electrically conductive ribbon.  The ribbon of the side seam is designed to overlap a substantial length of the sleeve seam.  The ribbons of the two sleeve seams and side seams overlap each other in the area of the collar.  An appropriate electrical connector is connected to the ribbon of at least one side seam.   An electrical conductor is to be connected to the electrical  connector  which  is  to  function  to  remove  static electricity that accumulates on the garment.  A second embodiment of garment has each side seam extending down each sleeve and terminates at the cuff.  Transverse ribbons are mounted across the torso section of the first embodiment, second embodiment, smock and pant  suit  garment  which  provide  a  dual  pair  of  electrical connectors each of which may be used to remove static electricity by being connected to an output electrical conducting grounding wire.  Boots and gaiters could be manufactured to include similar electrically conductive ribbons and hence be dissipative of static electricity.

Title: Tubing rotator
Inventor: CUPPEN NOLAN W
IPC: E21B33/04
Filed: 1997-12-10
Abstract: A tubing rotator and hanger is used in a wellhead of an oil well. The rotator has a rotator body including a flange and a sleeve projecting from the bottom end of the flange. The flange engages between the wellhead flange and the upper wellhead components, adding a very short height to the overall height of the wellhead. A mandrel extends through a bore in the rotator body and is supported in the body by a bearing supporting a load shoulder on the mandrel. A ring gear is keyed to the mandrel and is driven by a worm extending into a bore in the rotator body flange. In preferred embodiments, the load shoulder and ring gear can be removed from the mandrel, allowing the rotator body to be lifted off the mandrel and a BOP  installed when necessary.

Patent CA-2230602-A1 (CA)
Inventor: M NCH EGON
IPC: H04L12/56
Filed: 1998-04-02
Abstract: A multichannel decentralized radiocommunications system is known in which each station, before establishing a radio link to a neighboring station, scans all channels and creates a so-called channel occupancy list. The neighboring station can be used as a relay station by establishing a radio link to a further station in a corresponding manner ("radio chain"). Each station must thus have a scanning receiver.            In the radiocommunications system according to the invention, allstations (N1 to N7) transmit radio signals with respective identifications (I1 to I7) assigned to them. Each station (N3) has a memory which holds a first list (LA3) with those identifications (I2; I4) which this station (N3) receives directly from the at least one neighboring station (N2; N4), and a second list (LB3) with those identifications (I3, I1; I3, I5) which the at least one neighboring station (N2; N4) receives directly from its neighboring stations (N3, N1; N3, N5) and routes to said station (N3).            The stations are therefore simple in construction. The radiocommunications system can also be a single-frequency system.

Title: Gas turbine cooled moving blade
Inventor: TOMITA YASUOKI
IPC: F01D5/18
Filed: 1998-03-31
Abstract: The present invention relates to a gas turbine cooled moving blade in order to cool the gas turbine using steam alone.  In the moving blade, two cavities are installed in the lower part of the moving blade root section of the moving blade, a steam inlet is located in one cavity, and a steam outlet is installed in the other cavity.  Steam is charged from the steam inlet and passes through a serpentine cooling passage consisting of a plurality of steam passages, and discharged to the steam outlet and collected.  Bypasses are located near the base of the moving blade in the middle of each steam passage, so that cold steam on the leading edge side can be led into the bypass, mixed with the hot steam which comes from the tip section side and goes into the next downstream section of the steam passage, and flows to an upstream portion of the steam passage, thereby equalizing the steam temperature and cooling the steam over the entire range from the upstream to downstream of the steam flow.  A turbulator is installed in the middle of steam passage in order to generate turbulence and enhance heat transfer.          Since the moving blade is evenly cooled by steam alone without using air, and the steam is then collected, the performance of the gas turbine can be enhanced.

Abstract: A system for providing a fluid refrigerant to a cooling element is provided herein. The system includes a vessel which holds the fluid refrigerant, a heat source evaporating a portion of the fluid in the vessel, and a heat exchanger condensing a portion of the gaseous phase of the fluid in the vessel. A conduit establishes fluid communication between: (i) the vessel and the cooling element; and (ii) the cooling element and the heat exchanger. Importantly, the system controls the flow rate of the fluid refrigerant to the cooling element by controlling the pressure of the fluid in the vessel. The system is particularly useful with cryogenic fluid refrigerants to cool a superconductor for an MRI System.
