  • Patent number: 6649055
    Abstract: A pump station for transferring radioactive particle containing waste water, includes: (a.) an enclosed sump having a vertically elongated right frusto conical wall surface and a bottom surface and (b.) a submersible volute centrifugal pump having a horizontally rotating impeller and a volute exterior surface. The sump interior surface, the bottom surface and the volute exterior surface are made of stainless steel having a 30 Ra or finer surface finish. A 15 Ra finish has been found to be most cost effective. The pump station is used for transferring waste water, without accumulation of radioactive fines.

  • Patent number: 6646222
    Abstract: A method of electron beam welding a copper work piece to a stainless steel work piece is disclosed. In a continuous path on the work pieces, an electron beam is first directed on the stainless steel work piece. The electron beam is then moved across the interface to the copper work piece. The electron beam is then moved on the copper work piece in a path essentially parallel to the interface between the two work pieces at a specified distance from the interface. The electron beam is then moved across the interface to the stainless steel work piece and then terminated. The result is a high quality weld at the interface. The method is used for making a high quality weld on an electrical conductor such as a busbar.

  • Patent number: 6586704
    Abstract: A method for diffusion bonding ceramic layers such as boron carbide, zirconium carbide, or silicon carbide uses a defocused laser beam to heat and to join ceramics with the use of a thin metal foil insert. The metal foil preferably is rhenium, molybdenum or titanium. The rapid, intense heating of the ceramic/metal/ceramic sandwiches using the defocused laser beam results in diffusive conversion of the refractory metal foil into the ceramic and in turn creates a strong bond therein.

  • Patent number: 6474923
    Abstract: This invention generally relates to the remote removal of pelletized samples from cylindrical containment capsules. V-blocks are used to receive the samples and provide guidance to push out rods. Stainless steel liners fit into the v-channels on the v-blocks which permits them to be remotely removed and replaced or cleaned to prevent cross contamination between capsules and samples. A capsule holder securely holds the capsule while allowing manual up/down and in/out movement to align each sample hole with the v-blocks. Both end sections contain identical v-blocks; one that guides the drive out screw and rods or manual push out rods and the other to receive the samples as they are driven out of the capsule.

  • Patent number: 5578094
    Abstract: A method facilitating the deslagging of a partial oxidation reactor used to produce syngas is disclosed. The slag comprises vanadium trioxide and a siliceous material that accumulate on the interior walls of the partial oxidation reactor as a byproduct of the syngas production. The deslagging is accomplished by controlled oxidation, wherein the vanadium to glass weight ratio is maintained to at least about 3:2, operating the reactor at a temperature of at least about 2000.degree. F, and maintaining controlled oxidation conditions sufficient to convert the vanadium trioxide in the slag to vanadium pentoxide.

    Abstract: The gas fraction of a multiphase fluid is determined using `on-line` statistical methods and then using that fraction to compute the correct water fraction. The gas fraction (Xg) is detected by using the standard deviation of the raw phase (Pstd), maximum phase in the sampling interval (Pmax), average phase (Pavg) or standard deviation of attenuation (Astd) data and maximum attenuation in the sampling interval (Amax), or average attenuation (Aavg) from streams flowing in the water fraction monitor sensor cell where the conditions are determined.

  • Patent number: 5567396
    Abstract: Internal components for a vertical downflow reactor include a closed-ended conduit having an internal baffle and longitudinal exit slots proximate its closed end for the symmetrical introduction of quench fluid into a quench zone. An interzone mixing configuration is in vertical communication with the bottom of the quench zone. An inwardly sloping collector tray has an opening concentric with the vertical axis of the reactor vessel. A mixing device is provided for mixing the liquid and vapor components entering from above the collector tray and conveying the mixed vapor and liquid downwardly through the opening. Flow deflectors are positioned immediately below the collector tray opening for directing liquid flow towards the axial centerline of the reactor. The flow deflectors take the form of four pie-shaped plates which are configured to collectively occupy between 25 to 75 percent of the concentric circular opening the collector tray and may slope downwardly at an angle of from about 30.degree. to about 60.
