Organization And Execution Of A Major Industrial Electrification Project, Robert F. Mccaw

Professional Degree Theses

"All emergencies, especially those created by war, have marshalled the industrial might of nations, among other things. World War II was no exception; in fact, it produced the greatest expansion of industrial facilities in history.

Most all plants in the country underwent some degree of expansion. In certain industries, the experienced workers of existing plants were employed as nuclei for the organization of the gigantic new plants required to produce the arms and equipment necessary to the conduct of a global war.

This thesis pertains to one phase of the design and construction of such an enterprise. This particular phase …

Plastic Deformation Of Rocks, Muhammed Abdul Waheb

Masters Theses

"The purpose of this investigation is to search for a method by which the strength properties of a rock may be described.

For this purpose, an attempt has been made to find out some relationship by which the rooks may be classified or described. For the solution of problems of mine stability, the mechanical properties of a rock should be known, i.e., hardness, toughness and strength. It is difficult to make a study of some method of classification or description of a rock without knowledge of these properties.

With a view to achieve the solution of a general classification for …

Effect Of Viscosity On The Cetane Number Of A Diesel Fuel, Moris Bolay

Masters Theses

"The object of this paper is to determine or rather experimentally establish the effect of a change in viscosity of a given diesel oil in regard to the ignition quality (cetane rating) of the oil.

The author did not attempt to prove why or find out how much the cetane number was affected. But, merely, tried to experimentally verify the fact that the cetane number of the fuel used underwent a change when its viscosity was decreased by preheating it.

Since his professional interests lie in the field of automotive engineering, several thesis problems were suggested to him by Dr. …

A Survey Of Acidity In Drainage Waters And The Condition Of Highway Drainage Installations, James H. Havens

Kentucky Transportation Center Research Report

During the summer of 1949, approximately one year after installation, serious corrosion failures were discovered in a series of galvanized metal entrance culverts on U.S. 60 south of Ashland near Princess. Because of a unique disparity in their performance at this location, the problem was referred to the Research Division for possible explanation. An impromptu investigation ensued, and the cause of the failure was attributed directly to acid drainage water flowing from extensive strip-mining operations within the immediate area. A report (1)* describing the attendant conditions was made to the Research Committee in December of that year.

As an outgrowth …

A Compendium On Class I, Type C Mixes, Ellis G. Williams

Kentucky Transportation Center Research Report

Recently the Class I, Type C Surface Mix has been the subject of numerous discussions resulting from present paving operations on Muldraugh Hill (U.S. 31W and U.S. 60) south of Louisville, and from performance of pavements placed heretofore on some Louisville Streets. Apparently, past difficulties have created some doubt about the suitability of Type C surfaces in heavy traffic areas for which it was intended. Type C does not represent the ultimate in stable mixtures, but it should be entirely adequate for the purpose intended.

Dispersing Agents In The Pipette Method Of Soil Analysis, Eugene W. Price

Bachelors Theses and Reports, 1928 - 1970

For many years the study of sediments has been a major problem in the field of geology. Especially is this true of the branch of sedimentology known as grain-size distribution. Throughout the years many classical experiments have been performed and procedures evolved from them, all with the purpose of a better and easier determination of the grain-size distri­bution of fine sediments, particularly the clays.

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 …

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 …

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 …

An Experimental Study Of The Effect Upon The Current Distribution And Radiation Pattern Of Crossbars On Yagi Receiving Antennas, Gerald F. Sinnamon

Masters Theses

"The development and widespread use of radar systems in World War 11, and the post-war television boom, has brought about a large amount of investigation in antenna arrays. One of the types of antennas commonly used on radar systems during the early part of the war, and one which finds wide usage today as a television receiving antenna, is the well known Yagi antenna...

Since television antennas are usually mounted out of doors, the antenna must be made mechanically strong to prevent whipping or twisting due to wind, and to prevent sagging due to icing or to its own weight. …

A Study Of The Effect Of Jointing On The Blasting Of Granite, Graniteville, Missouri, Avery Ala Drake

Masters Theses

"Purpose of investigation: The purpose of this investigation is to attempt to determine the influence that joints exert upon the blasting of granite and if joints are induced by blasting. The problem grew out of an explosive evaluation project that was conducted by the Mining Department, Missouri School of Mines. In late May 1950, the project was moved into the granite area near Graniteville, Missouri. It became apparent upon study of this area that the jointing would have certain effects upon the results obtained. Dr. J. D. Forrester, Chairman, Department of Mining Engineering, Missouri School of Mines, Rolla, Missouri, suggested …

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 …

Clipper Amplitude Modulator, Durmuş Öcal

Masters Theses

"An amplitude modulated wave is defined as a wave form in which the amplitude of a sinusoidal signal (carrier) is varied in accordance with a modulating signal whose frequency is much lower than the frequency of the carrier signal. Numerous devices have been found for generating an amplitude modulated wave. In some modulators the amplitude of the carrier is actually varied in accordance with the modulating signal. In other types of modulators the carrier and the modulating signal are simultaneously applied to a nonlinear element or circuit. The output of this non-linear element is a distorted wave containing many frequencies. …

The Synthesis Of 2-Amino-4-Chlorophenol-6 Sulfonic Acid, Herman Albert Bronner

Theses

The work described in this thesis was undertaken with the view of exploring a reaction sequence suggested by early French investigators to synthesize 2-amino-4-chlorophenol-6-sulfonic acid especially in reference to the German claim that a low yield of product would result following this preparation, In particular, a successful application of this procedure would afford a relatively direct and inexpensive route to the sulfonic acid which is used as an azo dyestuff intermediate and could possibly find application in medicinal chemistry.

It was found that sulfonation and nitration of p-dichlorobenzene gave a high yield of the sodium-2-nitro-1,4-3 dichloro-benzene-6-sulfonate (91%) when using the …

Differential Thermal Analysis Of Some Carbonate Minerals, Paul L. Vandeveer

Bachelors Theses and Reports, 1928 - 1970

Thermal analysis is a relatively new method of determining the general composition of certain mineral substances. As is demonstrated by much of the literature previously written, clays and carbonates are especially adaptable to this method. The full importance of the method is not as yet realized, but it is rapidly approaching that point.

The Influence Of Copper Upon The Age Hardening Properties Of Steel, Andre Rey

Bachelors Theses and Reports, 1928 - 1970

The virtues of alloy steels have been widely publi­cized in both technical literature and everyday adver­tising. Nearly everyone possessing a slight knowledge of metallurgy knows the beneficial effects of chromium in the manufacture of stainless steels, or the importance of nickel, molybdenum, vanadium, and other common elements used to alloy steels.

The Gallium-Indium Constitutional Diagram, Richard E. Gaffney

Bachelors Theses and Reports, 1928 - 1970

Because of the discrepancy as to whether there is solid solubility in the gallium-indium system, and the fact that no alloys with less than 1% indium were ever investigated; the possibility of solid solubility in either or both ends of the diagram was not overlooked. According to Hume-Rothery, two alloys with the same relative positions on the Periodic Chart should have about the same alloying habits.

Chemical Analysis Of Igneous Rocks And Variation Diagrams Of Petrographic Provinces Of Montana, Frederick M. Hilpert

Bachelors Theses and Reports, 1928 - 1970

A total of 179 chemical analyses of igneous rocks are avail­able for the state of Montana, but these analyses do not cover the entire state in a satisfactory manner. There has been an emphasis on the central part of the state, and an almost complete lack of interest in the southern portion of Montana.

A Determination Of Reflectivity Of Opaque Ore Minerals With A Weston Ii Light Meter, Louis L. Bergan

Bachelors Theses and Reports, 1928 - 1970

Measurements of reflectivity of opaque ore minerals can be made with the common photographic light meter and a standard reflecting microscope, both of which are available to most Geology laboratories. During the course of the investigation, approximately 30 minerals were examined, of which 10 were duplicates. Comparable results, for the most part within 3% of previously determined valued, were obtained.
