Method and means for continuous precipitation of easy-dry, granular uranium peroxide

Patent Cahil, A.E.; Burkhart, L.E.

This patent describes a process of continuously precipitating easy-dry and flowable granular uranium peroxide from high vanadium content solutions. It comprises introducing a uranium mill solution having a high vanadium content with a vanadium to uranium mole ratio up to about 1:2, and a peroxide reactant solution along with a sodium sulfate solution in an outer zone of a reaction precipitation tank which has an interiorly disposed draft tube having open upper and lower ends, and an agitation means for continuous agitation of reacting mill solution within the draft tube; the draft tube defining an outer reaction zone between itmore »« less
Continuous production of granular or powder Ti, Zr and Hf or their alloy products

Patent White, Jack C. (Albany, OR); Oden, Laurance L. (Albany, OR)

A continuous process for producing a granular metal selected from the group consisting of Ti, Zr or Hf under conditions that provide orderly growth of the metal free of halide inclusions comprising: a) dissolving a reducing metal selected from the group consisting of Na, Mg, Li or K in their respective halide salts to produce a reducing molten salt stream; b) preparing a second molten salt stream containing the halide salt of Ti, Zr or Hf; c) mixing and reacting the two molten streams of steps a) and b) in a continuous stirred tank reactor; d) wherein steps a) throughmore »« less

Apparatus for the continuous precipitation of uranium peroxide

Patent Borner, P.; Isensee, H.; Vietzke, H.

A process and apparatus are described for the production of pourable, directly compactable uranium dioxide powder by continuous precipitation of uranium peroxide from a stirred uranyl nitrate solution at a pH of 1-2.5 with hydrogen peroxide, calcining of the peroxide at 500/sup 0/-800/sup 0/C. And subsequent reduction at 550/sup 0/-750/sup 0/C. Precipitation solution contains 70-150 g/l of uranium and 0.80 g/l of ammonium nitrate and is treated with 15-20% aqueous hydrogen peroxide solution in the ratio of U:H/sub 2/O/sub 2/ from 1:1.5 to 1:3 and there is led through the solution a mixture of ammoni and air having an air-ammoniamore » volume ratio of 1:0.3-0.6.« less
Means and apparatus for throttling a dry pulverized solid material pump

Patent Meyer, John W [Palo Alto, CA]; Daniel, Jr., Arnold D. (Alameda County, CA); Bonin, John H [Sunnyvale, CA]

Method and apparatus are shown for control of continuous feeding of pulverized material to a high pressure container. A rotor is located within the high pressure container. The pulverized material is fed from a feed hopper through a stationary feed pipe to a vented spin-up zone chamber to a plurality of sprues mounted in the rotor. Control of the pressure within control nozzles downstream from the sprues adjusts the flow rate of coal through the sprues.

Dry low combustion system with means for eliminating combustion noise

Patent Verdouw, Albert J.; Smith, Duane; McCormick, Keith; ...

A combustion system including a plurality of axially staged tubular premixers to control emissions and minimize combustion noise. The combustion system includes a radial inflow premixer that delivers the combustion mixture across a contoured dome into the combustion chamber. The axially staged premixers having a twist mixing apparatus to rotate the fluid flow and cause improved mixing without causing flow recirculation that could lead to pre-ignition or flashback.
