Title: Hardfacing for Progressing Cavity Pump Rotors
Inventor: MILLS ROBERT A R
IPC: F04C2/107
Filed: 1996-03-04
Abstract: A hardfacing for downhole progressing cavity pumps is disclosed as well as a method for producing same. The hardfacing consists of a metal carbide layer applied to the ferrous pump rotor body by way of plasma spraying and a top layerof metallic material having a lower hardness than the metal carbide. The metal carbide layer has a grainy surface with a plurality of peaks and intermediate depressions, the peaks being formed by metal carbide grains at the surface of the metal carbide layer. The thickness of the top layer is adjusted such that the depressions between the peaks of the metal carbide layer are completely filled thereby providing the rotor with a metal carbide hardfacing of significantly reduced surface roughness. In the process of the invention, the pump rotor, which may beprovided with a molybdenum bonding layer, is plasma coated with the metal carbide and the resulting carbide layer is covered with the metallic material top layer. The top layer is polished either until the dimensions thereof are within the tolerances acceptable for the finished rotor or until a majority of the peaks of the carbide layer are exposed. The hardfacing significantly increases the service life of the rotor and stator of downhole progressing cavity pumps.

Patent CA-2171733-A1 (CA)
Title: Composition and process for manufacturing lightweight inorganic particles, and resultant particulates
Inventor: ERTLE RAYMOND T
IPC: B29B9/02
Filed: 1993-09-17
Abstract: A method is provided for preduc-ing dense, free-flowing and non-calcing al-kali metal silicate-based particles which are heat expandable into lightweight par-ticles of a spumiform character. Pursuant to the invention, one provides at a se-lected temperature a dilatant aqueous gel comprising an alkali metal silicate as the majority non-aqueous component, the \ cate being present in the gel in a dissolved state; and the non-aqueous content of the gel being in the range of from about 38 to 65 % (w/w). Shearing forces are imposed upon the gel which exceed the flow re-sponse characteristics of the gel, whereby the viscosity of the gel becomes suffi-ciently high to cause a discontinuity in the gel, resulting in disruption into discrete particles. The discrete particles are con-ditioned while being maintained as sepa-rate entities to thereby form a skin on the particles so that they will not agglomerate or coalesce with one another. The condi-tioned particles are dried to form particles having about a 5 to 40 % (w/w) moisture level.

Title: Keratometer Having Photographically Produced Bore Pattern
Inventor: TIBBLING LARS
IPC: A61B3/10
Filed: 1995-01-23
Abstract: An improved conical keratometer (10) wherein the parent image of the pattern to be reflected upon a target positioned adjacent to the illuminated bore is recorded on a film slide (40) retained within the keratometer bore (12). Opposite edges (51, 52) of the slide (40) are chamfered at equal but opposite angles so that, when the spindeled slide is released) the chamfered edges (51, 52) will meet along a line of contact rather than butting squarely together.    The film slide (40) is rolled so that the emulsion side (53) is toward the periphery of the cone bore (12) and the chamfering allows that side to lie smoothly against the cone bore (12) without any gaps so that an undistorted image may reliably be reflected upon a standard target.

Filed: 1996-12-20
Abstract: A desiccant canister assembly for use in an air dryer system includes a pair of concentrically disposed casings, top and bottom end caps, top and bottom porous plates and moisture absorbing material.   A cylindrical opening is defined in between the casings.  The top end cap affixes to the upper ends of the casings.  The bottom end cap affixes to the lower ends of the casings.  Each end cap features openings that allow air to flow through the cylindrical opening.   The bottom porous plate is situated at a bottom of the cylindrical opening against the bottom cap.   The top porous plate is slidably disposed within the cylindrical opening near the upper ends of the casings.   The absorbing material is disposed within the cylindrical opening between the porous plates.  The desiccant assembly also includes a mechanism for compacting the absorbing material between the porous plates.   The desiccant assembly further includes a mechanism for aligning and securably retaining the desiccant canister assembly within a canister housing of the air dryer system.  The latter mechanism includes a positioning bore defined within an inner one of the casings and through a center of each end cap.  The positioning bore receives a threaded rod extending from a center of an upper base of the housing about which the desiccant assembly securably retains through a lock washer and a stop nut so that an outer ring portion of the top cap aligns with and seals via an o-ring against a sealing flange of the housing.

Title: Distributor assembly for multi-bed down-flow catalytic reactors
Inventor: STANGELAND BRUCE C
IPC: B01J8/04
Filed: 1996-04-19
Abstract: A multi-bed, down-flow reactor (10) includes several distributor assemblies (20) each having a centrally located mixing chamber (30) and an annular collecting and mixing trough (24) surrounding the mixing chamber (30). The mixing chamber (30) has an inlet (36) at one side thereof, an outlet (37) in its bottom wall (25), and a quench gas inlet (38) in its top wall (35) above the outlet (37). A divider wall (40) traverses the annular trough (24) adjacent to the inlet (36) to cause the pool of liquid collected in the trough (24) to flow in a circular pattern around the mixing chamber (30) to the inlet (36). This ensures that the liquid circulating through the trough (24) is well mixed with the liquid raining down from the catalyst bed. Turbulent and spiraling flow patterns generated within the chamber further mix the liquid and gas and entrain quench gas in the liquid and gas stream.
Patent CA-2198301-A1 (CA)
Inventor: WALES PETER ALEXANDER
IPC: G01N1/28
Filed: 1997-02-24
Abstract: A device for measuring metal purity, comprising a receptacle for holding a sample of molten metal, the receptacle being made, at least internally, from an insulating refractory material and having a bottom wall provided with a hole containing a filter element. The bottom wall is substantially impermeable to air except at the hole. An enclosed collection vessel is positioned below the receptacle for collecting molten metal which passes through the filter element from the receptacle, the collection vessel having an opening permitting extraction of gas from within the vessel to enable a vacuum to be generated within the vessel during use of the device. A leak-tight seal is established between the receptacle for molten metal and the collection vessel to permit vacuum generated in the collection vessel to draw molten metal into the collection vessel from the receptacle through the filter. The receptacle for molten metal has a heat diffusivity value that is sufficiently low that, in use, the temperature of the molten metal in the receptacle does not fall below the liquidus temperature in a period of time required for the vacuum to draw a fixed amount of molten metal sufficient for metal purity testing purposes through the filter and into the collection vessel from the receptacle. The invention also relates to a corresponding method, and to novel parts of the device.

Title: Power transmission for mechanical press
Inventor: HAYASHI KEIICHIRO
IPC: F16H33/02
Filed: 1993-03-16
Abstract: A power transmission shaft which transmits rotational energy of a flywheel is divided into a first shaft section adjacent to the flywheel and a second shaft section adjacent to a power take-off gear.  A planetary gearing is arranged between the shaft sections and is adapted to be driven by a servo motor.  A power take-off gear is mounted on an output section of the planetary gearing so as to transmit the power to drives.  A differential gear returns a part of the output of the power take-off gear to the input section of the planetary gear.  The servo motor controls the rotation of the output section of the planetary gearing to vary the rotation of the power take-off gear so that the action velocity of the slide or the like can be freely controlled and press working for different kinds of materials can be carried out.
