The Rolling of Thorium Rod

Description: Report discussing the rolling of thorium rods. Abstract: "Thorium rods, 1-7/16 inch in diameter, were rolled from Ames castings. The billets were roughed down in diamond-grooved rolls and finished in hand-rounding rolls. Remelted chips as well as primary-metal castings were rolled, and both yielded satisfactory rods. The surface quality of the rods was generally excellent, and the machined slugs were free of seams."

Geology and Ore Deposits of Yazzie Mesa, Apache County, Arizona with Recommendations for Exploration Drilling

Description: Abstract: Yazzie Mesa was examined in May 1951, by the writer, assisted by R. C. Cutter. The mesa shows one main channel deposit and three minor channels. The main channel appears to be a northern extension of a channel deposit being worked by the Vanadium Corporation of America at their Monument No. 2 mine. Two samples taken on the south outcrop of the main channel assayed 0.16% U308 over 4.5 feet and 0.80% U308 over 1 foot. The area is recommended for 10,000 feet of exploration drilling. It i… more

Observations on Bauschinger Effect in Copper and Brass

Description: Memorandum presenting a study of the effect of prestrain in tension upon the stress-strain characteristics in compression for copper and brass. The residual stress phenomenon known as the Bauschinger effect is of primary importance in cyclic loading, inasmuch as it serves to reduce the yield strength of plastically strained metal to deformation of the opposite sign.

Investigation at Mach Number 1.88 of Half of a Conical-Spike Diffuser Mounted as a Side Inlet With Boundary-Layer Control

Description: Experimental investigation was conducted at Mach number 1.88 to determine performance characteristics of half a 50 degree-conical-spike inlet mounted on a flat plate. Initial boundary layer was removed up-stream of inlet by a ram-type scoop of variable height. Initial boundary-layer thickness was also varied. With complete removal of initial boundary layer, total-pressure recovery of approximately 70 percent. Several alternative boundary-layer-removal systems were investigated which decreased t… more
