Final Report of Stainless Steel Connector Evaluation
The primary objective of the tests described herein was to determine if the standard five bend connector (drawing H-1-23475) and/or the T. F. Robinson three bend connector (drawing SK-1-20855) fabricated from Type 304 stainless steel tubing would satisfy the requirements of the K reactors. Results of the tests show that the standard five bend connector made from Type 304 stainless steel 0.065 inch wall tubing, in the as bent condition, with either cadmium plated Parker brass nuts and sleeves or cadmium plated high carbon steel nuts and sleeves, is suitable for installation of the K reactors.

Theoretical Considerations on Cell Shape, Convection, and an Area Anomaly Pertinent to Developing a Moving Boundary Theory for Ultracentrifugation
The intuitive concept that a sector shaped centrifuge cell is free from convection is criticized. Not only is a form of convection present for a single sedimenting species, but a more insidious type occurs in a mixture having an appreciable Johnston-Ogston effect. Rather than striving for convection-free sedimentation, the proposal is to utilize if possible an apparently harmless type of convection occurring in a very thin annulus in order to avoid the convection extending between boundaries in a mixture. The requirement that the concentrations be independent of time meets this condition and yields a hyperbolic cell, which is approximated by a sector cell placed in the rotor backwards. Simultaneously, area measurements and calculations involving the Johnston-Ogston anomaly are simplified because of the time independence.

The Rate of Uranium Sorption by a Strong-Base Anion-Exchange Resin
The rate of uranium sorption by a strong-base anion-exchange resin (Dovex 21K) from a uranyl sulfate solution (U 0.005 M, H2SO4 0.02M, SO4 0.2 M) was studied using a stirred vessel technique and measuring the U235 gamma radiation on each bead. Resin initially in the chloride form and the sulfate for was studied.
