Flow Distribution Across the Core. Test Results DL-S-182 (T-550097). Section II

Description: The purpose of the test was to determine the flow mixing characteristics of the lower plenum. Conclusion: Mixing appears to be quite small. The temperature indicated by the thermocouple nearest the cold loop decreased approximately 15 F. The cold loop temperature was 15 below the initial reactor coolant average temperature when the cold loop was places in services. The thermocouple furthest from the cold loop showed little or no change in temperature. The rate of change of reactor coolant tempe… more

Dynamic B and n-Behavior Up to 7600 Gauss in Magnet Model Mark Ii Comparison of Results With Long and Small Grad Coils

Description: "Magnetic measurements were performance at excitation levels ranging from 4000 to 7600 gauss, to study the dynamic behavior of the magnetic and gradient lengths of the CEA magnet sectors. The influence of the proposed metal vacuum chamber on field and gradient was experimentally determined. Results of measurements made with a 26 in. long grad coil and with small circular grad coils are compared. The reliability of the 26 in. long grad coil is demonstrated."

Path of Triple Point for spherical Shocks Above a Rigid Plane

Description: Paths of trip points of Mach reflections produced by 0.5-oz pentolite detonations have been observed for various burst heights. The slopes, Y, at points on the curved path are found to vary from values of Y predicted from plane shock wave data. This discrepancy is attributed to the shock strength conditions at the early inception of the Mach reflection, which later influence the triple point equilibrium, and in lesser degree to radius of curvature effects.

Operation of 1/4 Scale Model Bevatron

Description: Accelerated protons were first observed in the 1/4 Scale Bevatron on April 30, 1949. This is an account of some of the things learned since then. The results are still meager and must be considered provisional.

Stratospheric Monitoring Program

Description: "Design work was completed and construction initiated on a prototype field altimeter based on the gas density dependence of Townsend discharge current in an electrical discharge. The design of an ion tracer air velocity meter for laboratory applications, and construction of three units were successfully completed. Theoretical and experimental support is presented, showing the applicability of the ion tracer system to the accurate measurement of linear gas velocity. The operating range of the la… more

Strontium an Calcium Metabolism in Man, Final Report

Description: "During the first two years of this program the investigation centered around the distribution of strontium and calcium in tissues of persons who came to autopsy who had received a single tracer dose of Sr85 and Ca45. I then seemed desirable to attack some of the more dynamic aspects of strontium and calcium metabolism."

Chemical Properties of Sodium Triethylhydroborate and Sodium Triisopropoxyhydroborate

Description: Technical report abstract: Sodium hydride and triethylborane react to form sodium triethylhydroborate, NaBH(C2H5)3. This compound, a liquid at rooom temperature, was found to be soluble in hexane and mineral oil. A study was made of the thermal decomposition of sodium triethylhydroborate and its behavior toward boron trifluoride, boron trichloride, methyl borate, carbon dioxide, silane, and ethylene. Sodium triisopropoxyhydroborate, NaBH(OC3H7)3, was prepared and also found to be soluble in h… more

The Equation of State of Solids at Low Temperature

Description: Technical report describing and evaluating the the three experimental methods for obtaining equation of state data at low temperatures; (1) approximate measurement of the PVT relationship by a piston-displacement technique, (2) the measurement of a heat capacity at constant volume as a function of molar volume and temperature, and (3) direct measurement of the pressure variation of the elastic constants using ultrasonic techniques. X-ray methods also might be applicable.

Boiling Points and Surface Tensions of Mixtures of Benzyl Acetate With Dioxan, Aniline and Meta-Cresol

Description: Technical report. From Abstract : "Accurate measurements on boiling points and surface tensions of mixtures of benzyl acetate with dioxan, aniline and meta-cresol over the entire range of concentration are reported. The results have been analysed in terms of quasi-crystalline model which is partially successful in representing the composition dependence of heats of mixing, boiling points and surface tension except for composition dependence of boiling points of benzyl acetate and meta-cresol."

The Weighting of Intensities

Description: Technical report. From report : "The method of least squares refinement is based on the prediction of the theory of errors that, if the errors of the observed structure factors follow the Gaussian distribution, the most nearly correct atomic parameters will be those which result in the minimization of the residual R = Σi [√wi(|Fo| - |Fc|)i]2."

The Crystal Structure of Bis(Meta-Chlorobenzoyl) Methane

Description: Technical report. From Abstract : "The crystal structure of bis(meta-chlorobenzoyl) methane has been determined by three dimensional anisotropic least squares refinement of scintillation counter data. The molecule was found to be nearly planar with a maximum deviation from the least squares molecular plane of 0.068Å and an average deviation of 0.023Å. Fourier transform techniques to locate phenyl rings provided the key to the structure determination. The intramolecular bond distances and therma… more

Summary of the Research Progress Meeting of September 1, 1949

Description: The absolute excitation functions for the production of fission by charged particle bombardment in several substances were investigated at both high and low energies. The low energy work was done at the 60-inch Crocker cyclotron with alpha particles and deuterons, while the high energy work was done at the 184-inch cyclotron with alpha particles, deuterons, and protons.
