Aerosol collection efficiency studies were completed for IPC paper at 20,000 and 40,000 ft. Data developed in these studies indicate that ia the impaction and diffusion regions collection efficiency increases with altitude for all linear face velocities less than 800 ft/min. A propeller-type flowmeter, calibrated to measure the … more

Temperature and Phase Effects on the Photolysis of Ethyl Iodide

Description: "The elementary steps in the photolysis of liquid ethyl iodide by light of wavelength 2537 A by determining initial rates of iodine production in the presence of added iodine and hydrogen iodide were analyzed at 25 and --70 d C to get information on the activation energies of competing elementary reactions. Investigations were also made of the effects of additives on the photolysis of glassy ethyl iodide at --180 d C, and evidence for the formation of trapped radicals during photolysis and radi… more

Technical Report No. 3

Description: "Work towards the preparation of pure alkali halides is described. It was found that zone refining is an effective technique for the refinement of KCl. Four zone passed through one specimen of Harshaw KCl decreased its low- temperature conductivity by a factor of six. Kyropulos apparatus has been constructed to grow large single crystals in controlled atmospheres. It operates satisfactory in ambient atmospheres, but because of the high volatility of KCl at its melting point the viewing windows … more

The Armour Dust Fueled Reactor (ADFR)

Description: "Work has begun on the ADFR, a reactor using a new fuel form -- fissionable dust carried in an inent gas. Temperatures in the range 2,000 to 3,000 deg F appear feasible in an all-ceramic system. Experimental study of the fuel form was initiated, and a loop to circulate the fuel dust was constructed. Initial operation is encouraging. Theoretical studies were carried on in the areas of reactor physics, heat transfer, and safety."

Corrosion Resistant Brazing Alloys for Zircaloy

Description: "This is a progress report covering the first year of work on ARF Project B 080, "Corrosion Resistant Brazing Alloys for zircaloy". the objective of the work reported is the development of filler metals suitable for the brazing of zirconium base alloys in cases where the service environment of the brazement is to be high temperature water. The experimental approach has been necessarily a somewhat empirical one. During this first year of work some forty experiments of simple design for corrosion… more

Hyperfragments produced by K^o mesons from K^+ charge exchange

Description: "Stacks of C-2 emulsion were exposed to neutral k mesons. These were produced by the charge exchange, in dense material, of K^+ mesons from the Berkeley Bovatron. Hyperfragments were found in these stacks. It is concluded that the hyperfragments were produced by K^o2 mesons in the K^o mode. These were generated by the decay of the K^o1 component of the K^o beam as would be expected from the Gell-Man Pais scheme. Other possible mechanisms of production of the hyperfragments have been considered … more

Sampling the Upper Atmosphere for Particulate Matter. First Quarterly Progress Report, June 15 to September 25, 1959

Description: An analysis to screen the various particle-collection systems which might be used for sampling the upper atmosphere with a rocket sampling vehicle has been undertaken. Although the current model of the Goetz Aerosol Spectrometer is not suitable, a high-flow-rate sampler of this general type, if it can be designed, appears promising. The design of such a sampler will be undertaken in future work. If a workable design is possible, this method would appear to be the most promising of all.

Some Design Considerations for the Megatron Coil

Description: The relation between the maximum permissible transverse energies of particles that can be focused, the azimuthal energy, and the beam width is discussed relative to Megatron coil design. It is shown that deep potential wells for focusing can be obtained only at the expense of a narrow beam. (C.J.G.)

Equilibrium Extraction Characteristics of Alkyl Amines and Nuclear Fuels Metals in Nitrate Systems. Progress Report No. V for the Period July 1 - September 30, 1959

Description: Extraction of HNO3 by triaryl amine was studied by equilibrating equal volumes of aqueous and organic phases at 25C. At HNO3 concentrations of 2 to 10 N the acid in the organic phase in excess of that equivalent in the amine concentration was proportional to the concentration of HNO3 in the equilibrated aqueous phase. other workers report similar results with nitric acid and tri-n-octyl amine in benzene. Zirconium extractions carried out at 10g Zr/1 with 0.35 M TLA nitrate in toluene showed a f… more

Corrosion of INOR-8 and Inconel Dissolver Components of the Fluoride-Volatility Process

Description: The corrosion of INOR-8 and Inconel dissolver components used in the fluoride volatility process for the dissolution of zirconium with anhydrous HF in molten salts was investigated. Ten dissolution runs were made using simulated subassemblies formed from Zircoloy-2. The dissolver and components were made from INOR-8. Both the dissolver vessel and draft tube were examined several times during the series of runs. The solids which formed at different areas in the system were also analyzed. The res… more

Time Variation of Thermodynamic Parameters of a Gas in the Region of a Shock Front : Progress Report III

Description: The original goal of this investigation was to compare the thermodynamic characteristics of the gases in and behind the shock fronts in gases at initial pressures in the millimeter range and to compare these characteristics in the geometries of single and double discharges. The shock fronts were not visible, so it was not possible, at these pressures, to get visual data from the shock front itself. The parameters giving the properties of the gases were faces. Measurements made with an image con… more

Refinements of the Theory of the Infinitely-Long, Self-Acting, Gas-Lubricated Journal Bearing. Interim Report

Description: The lubrication equations for an arbitrary Newtonian fluid are derived directly from the general equations for conservation of mass, momentum, and energy. From the lubrication equations an inequality is obtained for the internal film temperature rise, after which the isothermal film equations are derived. Then, for perfectly-aligned self-acting journal bearings, a conservation equation is obtained. For gas bearings this condition gives: [formula] constant along the axis of the bearing. Applicat… more

Attempts to Delineate Inborn Anemias in Mice. Progress Report and Fifth Renewal Proposal, Report Period: January 10, 1959-January 31, 1960. Renewal Period: May 1, 1960-April 30, 1961

Description: During the past year, three papers covering results of a major series of experiments on intergenotype of blood-forming tissue have appeared, demonstrating successful implantation of isologues normal cells in anemic hosts, permanently correcting their genetic defect in hematopoiesis, both with and without irradiation of the host. Heavy host irradiation was shown ineffective as preparations for implantation of homologous cells of widely different antigenic types.

Progress letter No. 11 for January 1, 1960 through January 31, 1960

Description: A stainless steel autoclave for superheated water corrosion test was installed and "conditioned". Tests were begun to investigate the feasibility of densifying slip cast stainless steel by means of liquid phase sintering. Attempts to prepare tubular fuel elements by vacuum forming were resumed. Although thick-walled vacuum formed casting have been sintered on the aluminum mandrels without cracking, this has not yet been accomplished with the think sections of interest.
