Recovery of Uranium From Oil Distillation Residue
Abstract: The complete development of an effective process for recovery of the uranium in the residues from distillation of used Kinney and diffusion pump oils or similar oils is described. After considerable study and experimentation with several methods, a successful procedure has been developed. The recommended procedure embodies solution of the residues in trichlorethylene followed by extraction with nitric acid. Recovery of uranium is better than 99 percent effective and the method may be applied directly to contaminated oils as well as to their distillation residues.

Separation of Tuballoy From Tantalum by Chlorination Distillation Process
Abstract: Tuballoy can be effectively separated from tantalum filaments by chlorination of the filaments and subsequent distillation and condensation of tantalum chloride. Apparatus for chlorination of filaments and distillation separation in one unit is under consideration. Chemical methods of separation of tuballoy from distillation residues are being tested.

Pump-Down Times for the β⁺ Ray and Felix Experiments
"The e-folding time for the free-molecule pump-out time of the vacuum tank used for the β⁺ ray experiment (N¹⁹ at 20°C) is found to be of the order of 46 millisec, and that used for the Felix experiment (D₂ at 20°C) of the order of 12 millisec. In the Felix tank a particle bounces off of the walls on the average about 30 times before escaping, hence a "getter" material coated on the walls of the tube should result in a slightly more rapid pump-out time."

The Effect of Fabrication Variables on the Structure and Properties of UO₂-Stainless Steel Dispersion Fuel Plates
From introduction: "This report deals with a part of the research and development studies which preceded the manufacture of fuel elements for the Gas Cooled Reactor Experiment (GCRE)." The studies evaluate the effects of varying the type and size of UO2 particles, stainless steel matrix powders, blending procedures, compacting pressures, sintering times, temperatures and atmospheres, roll-cladding temperatures and reduction rates, total cold reduction, and heat-treating times and temperatures has been made for UO2 stainless steel dispersion fuel elements."
