Design basis for proposed separations facility, for use in preliminary project proposal

Description: Members of the Working Committees for RDA DC-4 and RDA DC-7 (KE and KW Reactors) have reviewed and approved the design basis being used for the preparation of the 200 Area portion of the Program X preliminary project proposal. This design basis includes the following: plant capacity of 275 tons per month, average flow rate; the basic chemical process used will be the Purex process; the plant will be located in the Southeast Quadrant of the 200 East Area; the plant will contain a double line of … more

Effects of High Intensity Radiant Energy on Skin: [Part] 1. Type of Energy and Its Relation to Energy Delivery Rate

Description: Abstract: Burn lesions were produced by radiant energy, 3100 A to 22000 A, on depilated rat skin. The gross and microscopic pathological changes so caused are described and correlated with the amounts of incident energy and the rate of energy delivery. Within the limits studied, 0.2 to 64 cal./cm.2/sec. and 0.1 to 8.0 seconds, it was found that increasing the rate of energy delivery lowered the amount of energy required to produce a specified degree of tissue injury. The tissue changes were in … more

Theoretical Investigation of the Stability at Negative Static Margins of a Supersonic Missile With an Autopilot Sensitive to Pitch Angle and Pitching Velocity

Description: Memorandum presenting stability charts covering a range of small positive and negative static margins for a supersonic missile with an autopilot sensitive to angle of pitch and rate of pitch. The results in the form of stability boundaries and lines of constant damping ratio and period show that time lags have an adverse effect on stability, but this can be counteracted by using ample gain in the rate-of-pitch feedback loop. Methods of simplifying the characteristic stability equation are discu… more

Effects of finite span on the section characteristics of two 45 degree swept-back wings of aspect ratio 6

Description: Report presenting a study of the finite-span effects on the local loading characteristics of two sweptback wings at low speed in order to provide some information about the usefulness of two-dimensional section data and span-loading theory for determining the section characteristics of a swept wing. At low values of lift coefficient, the finite-span effects were restricted to regions of the wing close to the root and tip. Results regarding the local pressure-distribution comparisons, local lift… more

Hydrogen Peroxide Analysis and Decomposition in Chromate Solutions

Description: Abstract: "A novel procedure employing ion exchange resins was developed to separate chromate ions from hydrogen peroxide, permitting, permitting the subsequent analysis of peroxide to determine its decomposition in sodium chromate solutions. At high pH's, peroxide was absorbed anionically on the ion exchange resins along with chromate. By selecting a resin which would be effective at nearly neutral conditions, chromate was satisfactorily separated from peroxide. It was found that the rate of p… more

Preliminary Studies for the Separation of HD from H2 by Rectified Absorption

Description: The feasibility of rectified absorption for the recovery and purification of HD from H2 streams has been investigated. The absorbent considered was liquid nitrogen at 78 (degrees) K. The process appears to present no major engineering or operation problems. Cost calculations indicate that the process may be economically competitive with other processes. Process design was based on an estimated separation factor of 1.25 between H2 and HD in this system. Experimental work has been undertaken… more

Effect of Various Blade Modifications in Performance of a 16-Stage Axial-flow Compressor. 4 - Effect on Over-all Performance Characteristics of Decreasing Twelfth through Fifteenth Stage Stator-blade Angles 3 deg and Increasing Stator Angles in the Inlet Stages

Description: "The performance of a 16-stage axial-flow compressor, in which two modifications of unloaded inlet stages were combined with loaded exit stages, has been determined. In the first modification the exit stages were loaded by decreasing the twelfth through fifteenth stage stator angles 3 deg. as compared with the blade angles in the original compressor, and the inlet stages were unloaded by increasing the blade angles the following amounts: guide vanes and first-stage stator, 6 deg; second- and th… more
