The Aplitic Body Bordering Roosevelt Drive South Of Butte, Montana, Edward B. Trueworthy Jr.

Bachelors Theses and Reports, 1928 - 1970

The area studied consists of a large body of aplite situated 12 miles south of Butte. It extends eastward almost to the Butte-Pipestone road, southward to Lime Kiln Hill and westward a distance of 3000 feet.

The petrographic work was supplemented by a map of the area. Special attention was given to those frequent "Limonite Specks" found in the aplite.

Joint Planes In The Rhyolites Of The Butte District, Montana, John B. Hopkins

Bachelors Theses and Reports, 1928 - 1970

The problem herein discussed deals with the pointing planes found in the area of rhyolite located in the northwestern portion of the Butte District. The question to be determined was whether or not the pointing planes in the rhyolites could be class­ified with the Butte Ore fissure systems.

A Bentonite Deposit Near Warm Springs, Montana, R. H. Larson

Bachelors Theses and Reports, 1928 - 1970

This report deals with a bentonite deposit recently developed, approximately seven miles northeast of Warm Springs, Montana. A group of claims have been staked on the deposit and are owned by the Lincoln Mining Company of Anaconda, Montana. The company also has several claims prospected for silver one mile from its present site of operations, but the silver prospects have failed to produce. The bentonite deposit was discovered incidentally during the course of other development work, and at present two adits have been driven into the side of a mountain, each crosscutting a vein-like mass of bentonite varying from two …

The Rate Of Precipitation Of Copper Aluminide In The Silver Rich Silver-Copper-Aluminum Alloys, Thomas Finley Mcbride

Bachelors Theses and Reports, 1928 - 1970

In order to determine the best annealing temperature at which to age-harden the alloys, hardness tests on speci­men annealed for different lengths of time at different temperatures were made.

The Effect Of Hydrogen Overvoltage On The Electrolytic Deposition Of Zinc, John M. Munzenrider, Kenneth O. Sweeney

Bachelors Theses and Reports, 1928 - 1970

In the deposition of metallic zinc by electro­lysis from neutral or acid solution, little difficulty is experienced provided certain impurities are absent from the electrolyte. The use of the process has long been considered as a potential source, patents on the process having been issued as early as 1880. However, the early experimenters failed to realize the importance of impurities in the electrolyte, and for this reason, the process suffered several severe setbacks when commercial plants were built.

The Electrolytic Deposition Of Chromium Upon Aluminum, E. Fults, L. D. Voerge

Bachelors Theses and Reports, 1928 - 1970

The purpose or this investigation is primarily to determine the best conditions for plating chromium on aluminum. The work was carried out with the hope of obtaining coherent deposits, and of determin­ing the conditions under which such deposits may be duplicated.

Fundamentals Of Bridge Design, Albert C. Kalmbach

Bachelors’ Theses

Man's earliest communication followed: water routes. Our prehistoric ancestors, evidence shows, fashioned boats and rafts which enabled them to travel along the rivers, and later to sail the seas. Following history through the years we will find man always developing theater routes for transportation before other methods. The early colonies in our America were along the coastal rivers; the Ohio and Mississippi river valleys were first settled in the interior.

Investigation Of Continuous Beams With Varying Moment Of Inertia By The Method Of Conjugate Points, Russell Arthur Bryant

Professional Degree Theses

"This design represents the application to a practical example of a rapid and direct graphic solution of the relation expressed by the Theorem of Three Moments. This method for obtaining moments in continuous beams eliminates the necessity of using arbitrary coefficients and gives the engineer an opportunity to exercise his ingeniuty [sic] and judgment toward obtaining efficiency and economy. The use of prescribed coefficients for continuous beams makes the design mechanical and unscientific and results in moments which may be 50% too small or 60% too large"--Introduction, leaf 1.

A Relationship Between The Mole Fractions And The Absolute Viscosities Of Blended Lubricating Oils, Ernest Reginald Epperson

Masters Theses

"The viscosity of binary liquid mixtures has been a subject of much investigation, but most of the work has been done with mixtures of substances other than lubricating oils. Lubricating engineers have found viscosity to be the most important property of a good lubricant, though up to the present time no one has succeeded in deducing a satisfactory expression by which the viscosity of a blended lubricant may be calculated from a knowledge of the physical properties of its components. This investigation has been an attempt to find a relationship between the absolute viscosity of a blended lubricating oil and …

The Control Of Anode Corrosion, Edward Arthur Godat

Masters Theses

"This particular study of the control of anode corrosion in connection with the production of zinc by electrolytic deposition from commercial solutions is a continuation of work started at the Missouri School of Mines and Metallurgy in 1929. It is not a new problem or even a new phase of the problem, but rather an attempt to confirm some of the ideas brought out in previous work and to perhaps more definitely establish some of the conclusions drawn from insufficient data, by more extensive tests and by attacking the problem from a slightly different angle"--Introduction, page 1.

Preliminary Construction Of A Photo-Electric Cell Concentrator, Stanley S. Williams

Bachelors Theses and Reports, 1928 - 1970

The separation of the valuable portion from the waste portion of an ore is an individual problem for every ore. However, the various methods for accomplishing this end, more or less classify themselves by the physical properties of the constituents of the ore. Most of the properties of minerals have been utilized in some way or other to affect the separation of the valuable from the invaluable parts. Practically nothing has been done so far with color and luster to attain this purpose.

It is believed that the photo—electric cell could also be used in concentrating a certain class of …

A Study Of The Plating Prohibitive Properties Of Various Separators, Bruno J. Pozorski

Bachelors’ Theses

The problem of this thesis is to study the plating prohibitive properties of the various materials commonly used in the manufacturing of separators, and to indicate which material would be most serviceable and feasible in a separator. At one time positives and negatives were kept not more than 0.25 inches apart, with the idea of reducing the intervening layers of electrolyte, and, therefore, the internal resistance of the cell, as much as possible. It was, however, found that the output could actually be increased by putting the plates at greater distances, the fact being that the larger bulk of solution …

Gas Analysis By Measurement Of The Thermal Conductivity, Bertie Lee Browning

Professional Degree Theses

"Types of gas analysis. Methods for the analysis of gases may be divided into two general classes, physical and chemical. In chemical methods, a constituent of the gas mixture undergoes chemical reaction and the amount of the constituent is determined by change in volume or by supplementary chemical methods such as titration. The physical methods of analysis differ in that no chemical change takes place in the gas. Instead, a determination is made of some physical property which is related to the composition of the gas mixture. Some of the physical properties which have been used for purposes of analysis …

Age Relationships Of Ore Deposits Of Southwestern Montana (A Microscopic Study), Charles R. Trueworthy

Bachelors Theses and Reports, 1928 - 1970

Although considerable work has been undertaken by some prominent geologists, the best known of which is that of Paul Billingsley and J. A. Grimes', in investigating the ore deposits of the Boulder Batholith and surrounding area, there has not been any complete microscopic investigation of these deposits, as a whole, published in the literature. With this in mind it was suggested to the writer by Professor Paul A. Schafer, of the Montana School of Mines, that a microscopic study of the ores of this region would be a worthwhile geologic problem.

It was thought that the mineral association and the …

A Preliminary Study Of The Separation Of The Copper Sulfides From Sphalerite And The Effect Of Certain Reagents On Some Of The Pure Copper Minerals In Synthetic Mixtures, Gailen T. Vandel

Bachelors Theses and Reports, 1928 - 1970

The problem of separating the copper sulfide minerals from sphalerite, in copper - zinc ores, has been a difficult one. This is largely due to the lack of adequate research and the small amount of data obtainable on the behavior of copper and zinc sulfide minerals in flotation circuits.
