Crystal Structures of Some Uranium Compounds : a Summary from the Ames Laboratory

Description: Introduction. Some forty different uranium compounds have now been given diffraction study at Ames. Reports of these investigations are scattered in the Project literature; many have been reported in a sentence or two as a note along with chemical or metallographic reports. To make the results of this crystal structure work more available this summary of the Ames work has been compiled. (A similar summary has already been published from the Chicago laboratory.)

The metal fabrication program for the Clinton Engineer Works and the Hanford Engineer Works. Including the Dummy Slug Program and the Unbonded Slug Program -- Project 1553

Description: The uranium slugs were used as the charge into the pile for the manufacture of minute quantities of plutonium. So little was known of uranium`s commercially adaptable physical properties that it was relegated almost to the category of a laboratory curiosity. A series of experimental and developmental programs were inaugurated to determine not only the extrudability, machinability and other physical properties, but also the influence on these of microscopic quantities of impurities present in th… more

The evolution of iodine during metal dissolution

Description: During the dissolution in nitric acid of uranium metal which has been irradiated in a pile, radio-iodine (8.0 day) and radio-xenon (5.3 day) are liberated along with the oxides of nitrogen. Since in the plant these gases are discharged into the atmosphere, the presence of the activities (particularly radio-iodine because of its greater chemical reactivity) presents a physiological hazard. As a consequence, the cooling period (that is, the time between the discharge of the metal from the pile an… more

The Metal-Dielectric Junction of High-Voltage Insulators in Vacuum and Magnetic Field

Description: From introduction: "This study is concerned with the shape of the electrodes of high-voltage insulator and with the method of joining them to the dielectric. The study is limited to insulators operating in vacuum, with special interest in the cases where strong magnetic fields are present. It is further limited to insulators with the high-voltage electrodes maintained at negative potential. The object of the study was to obtain information that would aid in improving the design of the insulator… more

Production and Properties of Ceramic Bodies of Alkaline Earth and Other Refractory Oxides

Description: Report discussing the properties and methods of forming ceramic bodies of alkaline earth and other refractory solids. These materials can be used for "reaction chambers, crucibles for melting metals, casting solids, insulation shields, thermocouple shields and other heat resistant bodies...High calcium lime was found to have the necessary chemical and thermal properties for many of the above uses."

Vacuum Probe, Standard Leaks, and Needle Valve for Use with the Helium Leak Detector

Description: The following report is split into four parts describing the usage of a vacuum probe for leak hunting with the Helium Leak Detector, the two types of Standard Leaks that were designed to measure the sensitivity of the detector, the development of a needle valve adjusted for controlling the flow of a standard mixture of helium and air into the leak detector for a sensitivity check by the single leak method, and a worm and gear adjustment developed to facilitate throttling of the Helium Leak Dete… more

The Effect of Geometry and Voltage Variations on the Operations of the Phillips Ion Gage

Description: Abstract: "The study of ten P.I.G. geometries with copper electrodes and d.c. voltage indicates that from a pressure of 0.1 to about 3.0 microns, depending upon the gage, there is a consistent change in the air pressure-current characteristics of a P.I.G. as the geometry and voltage are changed. At higher pressures discontinuities appear in the gage current and prohibit its use as a pressure gage. In all useful geometries, the greater the applied voltage above 1000 volts, the shorter the useful… more

A study of the Quartz Fiber Balance No. 1 (Information Report)

Description: This article is a de-classified document produced by Monsanto Chemical Company-Unit III in Dayton, Ohio. The date of the document is August 1, 1945, and the subject is the operation of a quartz fiber microbalance. In particular, the document examines whether temperature fluctuations affect the operation of the instrument. Data was presented to show that the accuracy of the instrument was indeed affected by ambient temperature.

Heat-Transfer Tests of Aqueous Ethylene Glycol Solutions in an Electrically Heated Tube

Description: "As part of an investigation of the cooling characteristics of liquid-cooled engines, tests were conducted with an electrically heated single-tube heat exchanger to determine the heat-transfer characteristics of AN-E-2 ethylene glycol and other ethylene glycol-water mixtures. Similar tests were conducted with water and commercial butanol (n-butyl alcohol) for check purposes. The results of tests conducted at an approximately constant liquid-flow rate of 0.67 pound per second (Reynolds number, 1… more

On Two-Dimensional Flows of Compressible Fluids

Description: "This report is devoted to the study of two-dimensional steady motion of a compressible fluid. It is shown that the complete flow pattern around a closed obstacle cannot be obtained by the method of Chaplygin. In order to overcome this difficulty, a formula for the stream-function of a two-dimensional subsonic flow is derived" (p. 1).
