Oil Shales In Montana, Richard N. Miller

Bachelors Theses and Reports, 1928 - 1970

Montana has long been known to have very large resources of coal and oil, and undetermined amounts of oil shale. The reserves of coal and oil have been proven, in part, and have been produced commercially, but not much is known about the extent and apparent value of the oil shales. Under present .conditions, and according to standards set by the United States Bureau of Mines, the shales are not of commercial value. They are, however, a potentially valuable mineral resource, and portions of them will possibly be utilized, although not in the near future.

Adaptation Of Diesel Rubber-Tired Loading Equipment To A Bedded Fluorspar Mining Problem, Robert Gill Montgomery

Professional Degree Theses

"The fluorspar-zinc orebody at Minerva No. 1 mine near Cave in Rock, in Hardin County, Illinois, would have been classed as non-commercial before the days of flotation milling and mine mechanization. The bulk of the ore requires fine grinding for acceptable beneficiation, and the assay of the head feed runs considerably lower than grades thought to be commercial in the fluorspar district prior to 1940.

However, the reserves found by drilling before the decision was made to invest in mine development, and the construction of a two-product, 250-ton, flotation mill, with complete power plant and surface shops, exceeded 600,000 tons. …

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 …

The Bloating Of Missouri's Shales, Peter Kurtz Jr.

Masters Theses

"The first objective of this investigation was to determine which deposits of clays, shales, and loesses in Missouri are suitable for use in the production of lightweight aggregate by virtue of their expanding characteristics upon heating. The second objective was to determine, if possible, commercially feasible additions that will produce the bloating property in shales that do not naturally bloat.

There are two conditions which must be met in firing in order to bloat a clay or shale. First, a gas must be formed and evolved during firing. Second, enough glass of the proper viscosity must be formed to trap …

The Lattice Constant And Coefficient Of Expansion Of Chromium, Chao-Ching Weng

Masters Theses

"The most important use of chromium, other than as an alloying element in the manufacture of stainless steel, is for electroplating; to form a coating on other metals for corrosion prevention in order to procure longer life, and to achieve a decorative effect.

The physical properties of chromium are important in the effectiveness of its uses, and its lattice constant, as well as coefficient of thermal expansion, seem worthy of exact determination.

A number of research workers, over a span of thirty years, have spent considerable effort in determining the aforementioned constants. However, their results do not check, and the …

An Investigation Of The Use Of Surface-Active Agents In The Secondary Recovery Of Oil By Water Flooding, Robert P. Schafer

Masters Theses

"The importance of producing oil cannot be emphasized enough in this modem world. Therefore, when primary methods of production seemingly exhaust the oil reservoirs, a secondary method of producing more oil is a necessity. At the present time, secondary methods of oil recovery have developed into a large industry. They are not a new development. The need of introducing compressed air or air-gas mixtures into the wells to increase production was quickly realized. Water flooding methods followed, and at first were restricted to the Eastern fields. Later, about 1935, systematic water flooding methods were developed and applied all over the …

Photoelastic Investigation Of The Stresses In A Capless Connecting Rod, Gerald Delaine Smith

Masters Theses

"For a great many years the primary method used to solve engineering problems was by the use of mathematics. However, rigorous and simple mathematical solutions are only possible if the geometry of the member and its loadings are relatively simple. When irregular shapes with complex loadings are encountered, rigorous mathematical solutions for stresses induced are either impossible or very cumbersome. In such cases, the engineer must resort to other methods which are available today.

This paper attempts to show the application of the photoelastic method to such a problem. Moreover, it will show the comparative ease with which the designer …

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. …

Runoff And Soil Moisture, John William Clark Jr.

Masters Theses

"Hydrology is the science treating of water from the time it hits the earth until it leaves the earth. This never ending movement of water is called the "hydrologic cycle" and is best summarized graphically. The hydrologist is primarily concerned with rainfall, runoff and evaporation. One of the basic aims of the science is to compute the surface runoff from any rain on a given area. Surface runoff is here considered as that water which reaches the channels without penetrating the ground, plus subsurface storm flow. Subsurface storm flow is slower than surface runoff but faster than ground water flow. …

The Effect Of Air-Entrainment On Concrete Containing Chert Gravel, Ali Erdogan Dinc

At the suggestion of Dr. Aaron J. Miles, the author decided to …

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 …

A.C. Circuit Interruption, Palmer L. Anthony Jr.

Masters Theses

"In the last few years the transmission voltages have increased tremendously. Along with the voltage increase came increased load carrying ability for the circuits. The first few links of a new 330 KV transmission system are now under construction in this country. Sweden is already operating a 380 KV line. It is expected to carry a load as high as 850,000 KW on a single circuit.

Interconnection between systems in adjoining areas is a practice to get further operating benefits. The benefits are - reduction of necessary reserve capacity, increased load diversity, and decreasing losses.

Both of these developments bring …

A Study In Emulsions, Edward Arthur Morse

Theses

An emulsion is a dispersion of one liquid in another liquid, the liquids being insoluble in each other. An emulsion consists of two phases, a continuous phase and a dispersed phase. The dispersed phase consists of tiny droplets or particles of one liquid which is completely surrounded by the other liquid comprising the continuous phase. One of the many factors affecting the stability of an emulsion is the size of the particle of the dispersed liquid.

This study is concerned with one emulsion prepared by different mechanical devices and under different conditions. The units of equipment employed are Eppenbach Colloid …
