Patent CA-2152254-C (CA)
Inventor: ROSCOE BRADLEY A
IPC: E21B47/10
Filed: 1995-06-20
Granted: 2005-07-26
Abstract: A method of measuring flow velocities in flowing fluids comprises injecting into the flow a non-radioactive tracer having a neutron capture cross section higher than that of the flowing fluids, for example a gadolinium compound, and measuring the neutron capture cross section in the fluid downstream of the injection point to detect the passage of the tracer and hence determine the time of flight. By making the tracer miscible with only one phase (typically the continuous phase) of a multi-phase fluid, it is possible to measure the flow velocity of that phase. The neutron capture cross section can be measured by irradiating with neutrons from a pulsed neutron generator and measuring capture y rays with a scintillation detector.

Abstract: An air drying cartridge  for use in an air drying system is disclosed.  The air drying cartridge comprises a telescoping casing resiliently  self  adjustable  in  height  which  has  an  inner cylindrical apertured wall and an outer cylindrical apertured wall.          The inner apertured wall has a facing surface, an upper end and a lower end.  The outer apertured wall has a facing surface, an upper end and a lower end.  The facing surface of the inner apertured wall is disposed to face the facing surface of the outer apertured wall thereby defining an opening therebetween.   The air drying cartridge also includes a porous filter liner, a pair of sealing caps and a moisture absorbing material for extracting moisture from air flowing through the air drying cartridge.  The porous filter liner is situated adjacent to each of the facing surfaces within the opening.  One of the pair of sealing caps affixes to the upper ends of the apertured walls and another affixes to the lower ends of the apertured walls.  The moisture absorbing material fills the opening between the filter liners and sealed therein between the sealing caps.   The telescoping casing resiliently withstands compressive  forces  that would collapse,  rupture  or otherwise distort prior art dryer cartridges.  The desiccant cartridge 30 exsiccates  air more  reliably and  efficiently than  prior  art desiccant devices.

Abstract: A joint of the integral type includes a male element 1 and a female element 2 with a diameter close to that of the tubes. Each of the elements has two shifted frustoconical threaded sections 4, 5, 6, 7 with vanishing threads at the two ends, by virtue of convergences of frustoconical envelope surfaces 16, 17, 18, and 19 and cylindrical surfaces 20, 21, 22, 23. A central abutment 24 cooperates with the negative- flank threads to reinforce the male/female connection and two internal 27 and external 28 ring-shaped meta/metal tightness zones, preventing the penetration of fluid into the threaded zones from the ends. The threaded joint may be used with tubes for very deep wells for which the reduction of the diameter of the assemblies makes it possible to lower costs, and other tubes for which a problem of the same type may arise.

Abstract: A triple layer fabric (13), useful in the forming section of a papermakers' machine, is provided. The fabric (13) has a top fabric layer having at least one set of warp yarns (11) interwoven with at least one set of weft yarns (12); a bottom fabric layer having at least two sets of weft yarns (14, 15) forming a top and bottom layer of the bottom fabric layer, and at least one set of warp yarns (16); and at least one binder yarn (18) interweaving and joining the top fabric layer and the bottom fabric layer. The top fabric layer is preferably a plain weave fabric while the bottom fabric layer is preferably a semi-duplex weave. Also, in one preferred embodiment, the weft yarns in the bottom fabric layer (14, 15) are generally stacked, as are the warp and weft yarns of the top and bottom fabric layers. The binder yarns (18) are preferably binder warp yarns, but may be binder wefts. In interweaving the top and bottom fabric layers, the binder yarns (18) engage only the upper weft yarns (14) or the warp yarns (16) of the bottom fabric layer. Thus, the binder yarn (18) is protected by the lower weft yarns (15) of the bottom fabric layer from normal wear and abrasion thereby increasing fabric life.

A resin part (3) is formed by extrusion molding along the varying cross-section part (2a) to continuously extend in the longitudinal direction, thereby realizing an excellent overall appearance. Such elongate composite members (1) can be readily and continuously manufactured basically with an extrusion molding process, wherein the elongate shaped body (2) is continuously and longitudinally fed into an extrusion die assembly (26) comprising a stationary die (31) and the movable die (32), through which the common cross-section part (2b) and the varying cross-section part (2a) are respectively passed in the longitudinal direction. The movable die (32) is moved in a direction intersecting the passing direction of the elongate shaped body (2) , in which the varying cross-section part (2a) varies during its passage in the longitudinal direction. At the same time, a resin is extruded from an extrusion orifice in the movable die, so that the elongate shaped body (2) is formed with the resin part (3) extending continuously in the longitudinal direction.
