The Analysis of TBP Process Streams for Calcium with the Flame Photometer

Description: Summary: A method was found for determining calcium concentrations in TBP process streams in spite of serious interferences bysodium, ferrous, uranyl, sulfate, phosphate, and sulfamate ions as well as by TBP. The precision attainable varied from sample to sample, depending upon its composition. In general, errors of 20% or greater occurred. The smallest determinable amount of calcium was about 10 mg/1.

Preliminary Study of the Pile Effluent Piping System

Description: In order to carry out the program of increased pile operating levels either tube outlet temperature or the water flows must be increased. This program proposes a considerable increase in both the pile effluent water flow and temperature. Consequently an investigation was started of problems that might be encountered in the pile effluent system. Later, a decision was made that the portion of this investigation dealing with the effects of increased water flow would be handled by the Pile Material… more

The low-speed lift and pitching moment characteristics of a 45 degree sweptback wing of aspect ratio 8 with and without high-lift and stall-control devices as determined from pressure distribution at a Reynolds number of 4.0 x 10(exp 6)

Description: A determination of the manner in which the lift and pitching-moment characteristics of a 45 degree sweptback wing are influenced by high-lift and stall-control devices by using detailed pressure-distribution measurements. The results indicate that the instability of the basic wing was due to flow separation which originated over the outer 4 percent of the wing semispan. The stability of the wing was improved through the use of upper-surface fences or leading-edge flaps.
