The Fluorescence Of Uranium In Solid Solution, Robert Emmett Kelly

Masters Theses

"The fluorescence of uranium finds its greatest application in the so-called "bead test" which is a method of qualitative analysis. In the form of a bead, the uranium is in solid solution, and if the proper chemical solvent is used, the bead will fluoresce under ultraviolet radiation.

In the systematic separation of the metallic elements, uranium is associated with the aluminum group in that it is not precipitated by hydrogen sulfide in 0.3 N H ion but is precipitated by ammonium hydroxide and ammonium sulfide. In the analytical scheme, uranium acts like beryllium. This process of detection is sometimes tedious …

An Efficiency Analysis Of Underground Haulage In The Tri-State Mining District, Leroy King Wheelock

Masters Theses

"Purpose of Investigation: This study was undertaken to describe and analyze the system of haulage as practiced in mines of the Tri-State District by the Eagle Picher Mining and Smelting Company.

The investigation is concerned with all of the operations involved in moving the broken rock and is composed of three distinct procedures: loading, hauling, and hoisting.

One of the important items in the cost of mining is the movement of ore and waste to the surface for further disposition. Increased efficiency of transportation should introduce lowered production costs.

In this paper the efficiency of the present equipment and the …

A Study Of The Dissolution Of Titanium In Acids With Ammonium Fluoride Added, Charles Burroughs Gill

Doctoral Dissertations

"Titanium can no longer be considered a rare metal, even though the modern era of its production came into being only a few years ago. The first discovery of titanium was in 1791 by an English clergyman, the Reverend William Gregor, and the name titanium became universally adopted when so called by a German mineralogist, Martin Klaproth, who rediscovered titanium three years later. Not until 1887 was the relatively pure, 75 percent, metal prepared by L. F. Nilson and O. Pettersson, whose experiments were repeated in 1910 by M. A. Hunter. Hunter is given credit for producing the first metallic …

Geochemical Prospecting Applied To The Illinois-Kentucky Fluorspar Area, Matthew Peter Nackowski

Doctoral Dissertations

"This study was completed to determine whether geochemical methods of prospecting could be applied to the search for fluorspar deposits in the Illinois-Kentucky fluorspar district.

During the course of the study, aspects of the geochemical cycle of fluorine under the climatic environment encountered were noted in the zone of weathering.

The Illinois-Kentucky fluorspar district supplies a large portion of the fluorite consumed in the United States. The producing deposits are of two geologic types. The vein deposits occur as nearly vertical tabular lenses or pods which occupy fractures. These deposits may reach the bedrock surface, but in any case, the …

The Application And Utilization Of Mining Models For Instruction And Display, William M. Shepard

Masters Theses

"The subject of the utilization of mine models for instruction and display at institutions offering courses in mining engineering has not been widely discussed in the literature. The value of models as visual aids in teaching has long been recognized, and they have been extensively employed by some institutions and by some instructors. However, the writer believes that a wider range of types of models are suitable for instruction purposes than have been employed in the past, and that mining models, properly arranged and adequately labelled, may be used in displays to give both the layman and the beginning student …

A Study Of Size Of Diamonds In Diamond Drilling, Robert J. M. Miller

Masters Theses

" ''A Study of Size of Diamonds in Diamond Drilling' is the research problem which will be discussed in this treatise.

The author's interest in the effect of size of diamonds was created by Mr. R. D. Longyear of the E. J. Longyear Company of Minneapolis, Minnesota. Mr. Longyear, when asked for suggestions for a research problem concerning diamond drilling suggested, among other things, that there was a need for further work on the factor of size of stones. After extensive reading and reviewing, the author learned that many investigators had recognized changes in results attributable to changes in size …

A Comparison Of The Real Price And Market Price Of Some Common Metals, Kon-Hock Khaw

Masters Theses

"A number of complex factors influence the fluctuation of the price of a metal. In this investigation, the writer is concerned with the influence of the purchasing power of the dollar and, therefore the difference between the value (real price) and market price of nine metals. That is, this is a study of metal prices and their corresponding values. No attempt is made to analyze the supply and demand of the past or the future, except as they are expressed by their function -- price.

To aid in the comparison, a set of index numbers for metals is compiled and …

Determination Of Progressive Corrosion Of Clay Flux Blocks, Ved Prakash Maheshwary

Doctoral Dissertations

"The Problem. Corrosion of refractories by molten corrosive liquids like molten slags and glasses is of general occurrence in those parts of the furnaces where they come in contact with the liquids. The life of a furnace generally depends upon the progressive rate of corrosion of the refractories by the slags and glasses. There have been various methods used by the investigators to ascertain the useful life of a refractory product before its use in the furnaces, but the problem is so complex that even after decades of research work by the research engineers and technologists a satisfactory and easy …

Porosity-Permeability Relationships Of Unconsolidated Sands, Robert Marchel Ponder

Masters Theses

"Unconsolidated sand reservoirs containing oil and gas present difficult problems to the petroleum engineer. Among these problems is that of the determination of the reservoir porosity to facilitate oil and gas reserve and evaluation calculations.

This problem is especially difficult because, to the author's knowledge, no method has been devised to obtain a core sample of the unconsolidated sand that retains the same porosity and permeability characteristics in the laboratory as it had underground. As a result, the petroleum engineer must rely upon empirical methods of calculating the reservoir porosity when the sand is not consolidated.

Many investigators have attempted …

X-Ray Studies Of Zirconium Cyanonitride, John T. Ballass

Masters Theses

"The purpose of this research was to study, by means of x-ray and metallographic analysis, a material reported to be zirconium cyanonitride.

The x-ray analysis had a three fold purpose, the determination of the symmetry of the constituents, the number of phases present, and the crystal structure type. Metallography was used to confirm some of the results obtained by x-ray analysis establishing certain definite phase relationships present in the microstructure.

The sample investigated contained three principal elements namely zirconium, nitrogen, and carbon. On the basis of constitution this work is a contribution toward the development of the three component equilibrum …

Hydrology Of Small Drainage Areas, James Kinchen Searcy

Masters Theses

"Realizing the need for data on small drainage areas the Missouri Highway Commission in 1947 began a cooperative project with the Water Resources Division of the United States Geological Survey which includes the establishment of small area gaging stations and recording rain gages.

The purpose of this investigation is to study some of the data collected in the few years of operation of these small area stations with the aim of testing some of the hydrologic tools useful in the study of larger drainage basins to determine their applicability on small drainage basins. The relationship between the runoff of large …

An Investigation Of End-Anchorage And Performance Of Sr-4 Strain Gages On A Prestressed Concrete Beam, Howard W. Nunez Jr.

Masters Theses

"In recent years there has been brought to the attention of engineers and architects a new medium of construction---prestressed concrete. Reinforced concrete has long been recognized as a satisfactory material for use in the construction of buildings, bridges, highways, tanks and other structures. However, most concrete designers will concede that this material has many drawbacks. For instance, in a simple beam of rectangular cross-section, roughly only one half or the concrete is relied on to resist compressive forces. The tensile strength of the concrete is considered to be zero, and steel bars or rods must be inserted to carry the …

Direct Reduction Of Zinc Sulfide Under Vacuum, Merritt E. Langston

Masters Theses

"The present work is a continuation of the previous investigations of Gross and Warrington and Liu in which the effect of various reducing agents on the vacuum reduction of zinc sulfide was studied. The author became interested in this topic while reading the papers by these investigators in which they recommended that further work be performed in an attempt to prevent zinc sulfide from distilling over during reduction, thereby contaminating the zinc condensate. The original plan was to perform a few runs for the purpose of duplicating the results that were reported by Liu, and from this point carry on …

Integrated Scattering Of Microwaves By Small Metal Spheres, A. L. Merts

Masters Theses

"When electromagnetic radiation falls upon a material body of any kind, the associated electric field induces periodic oscillations of the electrons of the material synchronous with the incident radiation. The material serves as a secondary source and emits energy in the form of scattered radiation with a frequency equal to that of the incident electromagnetic wave. The polarization and intensity of the scattered radiation are determined by the size, shape, electric constants, and interactions among the scattering elements.

The scattering of electromagnetic waves is an old problem in physics. Such names as Rayleigh, Debye, and Mie have become associated with …

Well Interference In The South Silica Field, Langdon B. Taylor

Masters Theses

"During World War II the Federal Government restricted oil-field drilling in the United States in order to conserve steel. The wartime regulations required 40-acre spacing in most areas. At the close of the war, the Federal drilling restrictions were lifted, and control of oil-well spacing reverted to the several state regulatory bodies. Each of these state agencies was then confronted with this problem: should 40-acre spacing be continued or should pre-war 10- and 20-acre spacing patterns be re-established?

The regulatory authority in Kansas, the State Corporation Commission, ordered an investigation in January, 1946, for the purpose of developing information upon …

Problems In Theatre Lighting And Pre-Selective Elctronic Lighting Control, Hasan Orhan Aker

Masters Theses

"Until the recent years, because of the lack in technical know-how of play producers and on the other hand the limited knowledge of the engineers about stage technique, all the advantages provided by efficient stage lighting could not be exploited. Especially, the different problems encountered from the point of view of lighting control, could not be solved for a long time.

It has been proven from theatres built lately, that the stage lighting designs made without a thorough study of the various stage conditions and requirements lead to a tremendous increase in cost and also inefficient operation of the whole …

The Reactions Of The Sodium-, Potassium-, And The Lithium Tungsten Bronzes In The Solid State, Keki Khodadad Irani

Masters Theses

"The first part of this dissertation has the intention of determining whether MoO₃ forms solid solutions with Na-W bronze corresponding to the formula NaWO_3(1-x) (MoO₃)_x and whether the so-called “sodium-molybdenum bronze” exists.

The next part is concerned with the solubility of K-W bronze in Li-W bronze at high temperatures, in a vacuum, and the last part or this work has the intention of studying the solubility of K-W bronze in Na-W bronze at different temperatures.

The interest in this work is of a purely scientific nature rather than of academic interest"--Introduction, page 1.

The Use Of Oil-Base Drilling Fluids, William Wesley Collins

Masters Theses

"Within the past few years the development of oil-base drilling fluids has become one of the more important contributions to drilling and production technology. The use or these new muds has increased as the benefits obtained have become more widely known and appreciated. Major problems in the petroleum industry have been, for many years, the contamination or drilling muds by salt water; control of mud when drilling through anhydrite, gypsum, or salt deposits; control of heaving or swelling shale; and water or mud blocking or the producing horizons. The development or oil-base drilling fluids is a direct contribution or engineers …

The Relationship Of Regional Structural Geology To The Ore Deposits In The Southeastern Missouri Mining District, Jack Alexander James

Doctoral Dissertations

"The lead deposits in the Southeastern Missouri mining district have been examined by numerous geologists and mining engineers since the original discovery about 1720. A list of the men who have reported on them includes some of the outstanding students of ore deposits.

The regional geology in the mining district either was unknown or only vaguely known when most of the early examinations were made, and the discussions of the structural geology are restricted in scope owing to the lack of detailed information. The reports based on these examinations, although excellent for their time, are incomplete in view of the …

A Light Source To Be Used With A Vacuum Spectrograph, Roy George Woodle Jr.

Masters Theses

"A grazing incidence vacuum grating spectrograph for use in the vacuum ultraviolet was designed and partially constructed by Mr. L. H. Chapin, as a research project for a Master’s Degree. This instrument is designed to photograph the region of the spectrum from 100 Å to 1000 Å. As Boyce pointed out in his exhaustive review, there is much important observational work to be done in this region.

The author of this paper has undertaken to develop a satisfactory source for the region from 100 Å to 1000 Å. This is part of a project to photograph the emission and absorption …

A Lead Sulfide Near Infrared Detection System, William V. Cummings Jr.

Masters Theses

"The infrared region of the spectrum is conveniently divided into the near infrared, which extends from the red end of the visible to about 25 microns, and the far infrared, which continues to an ill-defined division point of approximately 1,000 microns. The near infrared region has been further subdivided on the basis of instrumental techniques so that the particular portion of the spectrum consisting of radiations of wave length up to 3 microns has become known as the photoelectric infrared.

Several types of detection instruments have been designed and perfected for work in the photoelectric region, but new methods and …

A Method Of Mining The Kumtepe Lignite Deposit Of Turkey, Hilmi Dokuzoglu

Masters Theses

"The Agacle lignite deposit, as a potential source of fuel, near Istanbul, Turkey has been used in this study to apply the principles of strip mining operations. The details of the deposit upon which this thesis is predicated will be presented later in this paper.

The fuel requirement of the city of Istanbul with a population of nearly a million is considerably greater then can easily be met. Some of the fuel needs are accommodated by electrical energy by producer gas, by bituminous coal brought from Zonguldak (about 200 miles from the city), by charcoal, and by fuel wood. During …
