The Determination of Thorium in the Presence of Uranium, Titanium and Tungsten

Description: Abstract: "Thorium is separated from uranium, titanium and tungsten by precipitation as fluoride. The precipitate is ignited to oxide, dissolved in nitric acid, evaporated with perchloric acid, neutralized to a pH between 2.0 and 2.5 and titrated with the disodium salt of ethylene-ddiamine tetrascetic acid, using Eriochrome Cyanide as indicator. If less than 30 milligrams of thorium is present, lanthanum is added as a carrier."

Directional Stability of Towed Airplanes

Description: "So far, very careful investigations have been made regarding the flight properties, in particular the static and dynamic stability, of engine-propelled aircraft and of untowed gliders. In contrast, almost no investigations exist regarding the stability of airplanes towed by a towline. Thus, the following report will aim at investigating the directional stability of the towed airplane and, particularly, at determining what parameters of the flight attitude and what configuration properties affe… more

Effect of climb technique on jet-transport noise

Description: From Summary: "A theoretical investigation of jet-transport climb technique was made to determine the effect of variations in engine thrust and airspeed on sound-pressure levels heard by a ground observer. Reducing either thrust or climb airspeed results in reduced sound-pressure levels. Reducing thrust decreases the sound power radiated; decreasing climb airspeed permits the initiation of climb sooner and hence results in increasing the source to observer distance."

The Effects of Chemical Impurities on the Quality of Rolled Uranium Rod

Description: Abstract: "The effects of nitrogen, slag, and hydrogen additions on the surface quality of rolled uranium rod were studied. The addition of 400 ppm of nitrogen resulted in severe striations. Slag inclusions elongated during rolling and produced short open seams in the etched surface. The effects of 9 to 10 ppm of hydrogen were obscured by defects in the original costings. These defects were caused by oxide films entrapped in the ingot."

Experimental and calculated temperature and mass histories of vaporizing fuel drops

Description: Report presenting a comparison of experimental and calculated mass and temperature histories of drops vaporizing with a constant velocity relative to the air. The results indicate that the unsteady state or time required for the drop to reach the wet-bulb temperature is an appreciable portion of the total vaporization time. Results regarding the measurement of surface and center temperature of drops, internal circulation in drops, heat transfer from thermocouple to drop, experimental temperatur… more

Experimental investigation of air-flow uniformity and pressure level on wire cloth for transpiration-cooling applications

Description: Report presenting an investigation of the problem of producing uniform air flow through a calendered or cold-rolled sheet of brazed stainless-steel corduroy wire cloth on 20x250 mesh cloth in regions of low permeability. The effect of exit level was determined at several exit level pressures on three different types of mesh wire cloth. Results regarding airflow uniformity for calendered wire cloth, effect of exit pressure or pressure level on air flow, and permeability and strength of 20x200 me… more

The Extraction of Uranium from Phosphate Solutions

Description: Abstract: "A process for the extraction and depoisoning of uranium in strong phosphoric acid solution with tributyl phostphate (TBP) is described. The formation of a complex between uranyl and phosphate ions necessities the use of a salting agent which is capable of destroying this complex and releasing the uranyl ion into an organic extractable species. Of various salting agents tried, ferric nitrate was the most successful. It not only provides nitrate ion for the formation of uranyl nitrate … more

Flammability of Hydrogen-Air-Nitrogen Oxide Mixtures. Final Report

Description: Limit-of-flammability test were conducted on various hydrogen-air-nitric oxide-nitrous oxide mixtures at one atmosphere pressure and at 28 degree C. The data used to define the limits of flammability of the above mixtures are presented in tabular and graphic form and are used to construct a flammable volume in a regular tetrahedron in which the apices are pure H2, air, NO and H2O.

Geology of Devils Tower National Monument, Wyoming

Description: From abstract: Devils Tower is a steep-sided mass of igneous rock that rises above the surrounding hills and the valley of the Belle Fourche River in Crook County, Wyo. It is composed of a crystalline rock, classified as phonolite porphyry, that when fresh is gray but which weathers to green or brown. Vertical joints divide the rock mass into polygonal columns that extend from just above the base to the top of the Tower.

Geology of the Christmas Copper Mine, Gila County, Arizona

Description: From introduction: The exploration project at Christmas was carried on cooperatively by the Geological Survey and U. S. Bureau of Mines. Mr. 0. M. Bishop, Engineer for the Bureau of Mines, examined the property and in his report of June 6, 1942 recommended that six holes be drilled from the 800 level of the mine. The Bureau of Mines began drilling in September 1942, and the Survey investigations began a month later. Since any ore bodies discovered below the 800 level would be inaccessible until… more
