Ceramic Materials And Products That Have Present Or Future Significance In Montana, W. Wurth Kriegel, John D. Keyes

Bachelors Theses and Reports, 1928 - 1970

The collection of stories compiled in this pamphlet were originally written for radio broadcast over Montana radio stations. It must be understood that these stories do not cover the whole field of ceramics nor do they in any sense give a complete historical or technical summary of any one field or subject discussed. In each case, those subjects have been treated that apparently have present or future significance in Montana.

Sherardizing As Applied To Stampings From Light Gauge Metals, Matthew Patrick Brazill

Professional Degree Theses

"Sherardizing, or dry galvanizing as it is sometimes called, is a process whereby articles of iron or steel are rendered rust proof by applying a coating of zinc. The coating produced by this process is first an alloy with the underlying metal. After this alloying action is completed the outer layer of zinc is deposited. Briefly stated, this coating is not a pure layer of zinc, but a zinc iron alloy"--The History of Galvanizing, page 1.

The Effect Of Electrical Lubrication On The Transmission Of Pressure In Dry Pressed Bodies, Oliver William Kamper

Bachelors Theses

"One of the great problems facing the Ceramic industry today is the production of perfect brick by the dry press process. This problem has been of vital importance because of the physical defects obtained in the dry pressing operation due to the ununiform transmission of pressure in the ware produced. As a result of this ununiform transmission of pressure, strains, cracks, differential shrinkage, low strength, and laminations have been accentuated after the firing of the body. Pressure transmission is influenced by several factors: the size and shape of grog and clay grain, the time and duration of pressure application, the …

The U.S.G.S. Topographic Map: Its Value And Method Of Construction, Daniel Kennedy

Professional Degree Theses

"Topographic maps, which differ from the base map in that they show not only relative distance and direction but also the accurate shape of the earths surface, are not new, but represent the constant improvement in mans efforts to reproduce on paper all that he sees and knows of regions of the globe.

While history records the first maps known to man as being made by the Babylonians on clay tablets centuries before Christ, the first relief map was made by the Ninth Inca who died in the year 1191. The present method of showing relief by contours was employed …

Development Of A Refractory Insulating Brick, Edwin Laughlin Dudley

Bachelors Theses

"The method of bloating brick of low refractoriness has been accomplished by the addition of carbonates of the alkalines and alkaline earths which when acid is applied give off CO₂ to form a porous structure. It was thought that if a material which would not act as a flux might even enhance the refractoriness of the clay used a high temperature insulator might be produced which would compare favorably to those now produced by the use of volatiles. An aluminum salt which when combines with a non-metalic sic base that would generate a gas was selected. The aluminum in the …

The Use Of Missouri Halloysite As A Suspending Medium For Enamels, Collins H. Mcdonald

Bachelors Theses

"The object of this study was to find if Missouri halloysite could be used satisfactorily to float enamel frits, preventing them from settling during the spraying or dipping operation, so as to get a uniform coating of proper thickness over the surface of the ware. Halloysite is a clay-like natural aluminum silicate resembling kaolinite, but containing a larger but uncertain amount of water. The material that was used in this investigation was found in Lawrence County, Missouri"--Object of Investigation, page 1.

A Preliminary Study Of The Micro-Fauna Of Certain Paleozoic Formations Of Montana, George Powe

Bachelors Theses and Reports, 1928 - 1970

The study of the micro-fauna of Montana formations has been almost entirely neglected. Because the petroleum industry of this state has not felt the necessity for using micro-paleontology in its sub-surface correlations, the science has been but little used. The Montana Power Company has had an examination made of some of its well cuttings by a competent micro-paleontologist who found some foraminifera in Mesozoic sediments. However, no investiga­tions have been made to determine the presence and character of the micro-fauna of the Paleozoic formations of Montana.

The Effects Of Zinc Sulphate, Manganese Sulphate, And Iron Sulphate On The Lead Storage Cell., George A. Mccracken

Bachelors Theses and Reports, 1928 - 1970

The lead storage battery as it is used today is made up of the pasted type plates of lead dioxide, the anode, and sponge lead, the cathode, and wooden or hard rubber separators, which serve to insulate these from one another. In manufacturing these, it is desirable to keep them free from impurities.

An Acoustical Investigation Of Parker Hall Auditorium At The School Of Mines And Metallurgy Of The University Of Missouri, John Douglas Martin

Masters Theses

"The auditorium in Parker Hall on the Missouri School of Mines campus has been noted locally for its poor auditory characteristics. At times in the past corrective treatment has been considered but no detailed or experimental data were gathered. In September of 1934 the writer was detailed under an FERA project to study the room and to determine the best method of correction"--Introduction, page 1.

The Fluorine And Manganese Content Of Certain Missouri Waters, Erwin Charles Hoeman

Masters Theses

"Since early in 1931, considerable attention has been brought to bear upon the subject of fluorides in drinking water supplies, following the discovery of high fluoride concentrations in waters consumed by persons afflicted with the dental defect known as mottled enamel. Analyses have been made, in the course of this study, of a comparatively large number of Missouri waters. The waters analyzed have been collected and made available by the Missouri Geological Survey and Water Resources. They have been secured from diverse sources and include surface waters and underground waters from different geological formations, throughout the State of Missouri"--Introduction, page …

The Rahway Valley Trunk Sewer And Its Relations To, And Effect Upon The City Of Rahway, Fred A. Hedeman

Theses

This treatise is divided into three separate parts, each portraying a particular phase of the Rahway Valley improvement. Although not directly connected with the Joint Meeting, the fact that I served as Assistant City Engineer in Rahway during 1931 and 1932 naturally presented to me the opportunity of attending meetings and studying the project especially as it pertained to the City of Rahway.

Part one is a general review of the activities of the Rahway Valley Joint Meeting, both prior to and after the completion of the trunk sewer. The second portion reveals some of the intricate problems evolving in …

Bachelors Theses and Reports, 1928 - 1970

The Butte-Highland mine is situated at the head of Basin Creek, in the Highland mining district, Silver Bow County, about 14 miles south of Butte. The tunnel portal and present surface plant are at an elevation of about 7350 feet above sea level, facing westward across the head of Basin Creek valley. The "ghost" mining town of Highland lies a mile to the east, near the forks of Fish Creek. Access to the mine is obtained at present from Beaudine's siding, 12 miles west. The property may also be reached, with difficulty, over poor roads from Limekiln hill, or from …

Preliminary Floatation Tests On The Beneficiation Of A Low-Grade Montana Bituminous Coal., William Packwood Given

Bachelors Theses and Reports, 1928 - 1970

Coal is an aggregation of vegetal matter with varying small amounts of mineral and animal matter which have been so changed by the processes of sedimentation, decay and metamorphism that it has become a dense, dark, combustible substance. It occurs in beds varying in thickness from one foot or less to over 300 feet. The horizontal extent of a bed is sometimes continuous over an area as large as the State of Montana.

Auriferous Tertiary Gravels Near Rocker, In Silver Bow County, Montana, William C. Mclaughlin

Bachelors Theses and Reports, 1928 - 1970

Between the villages of Rocker and Silver Bow, in south­western Montana, are found an interesting group of placers. Gold occurs in Tertiary gravel beds that are interstratified with beds of rhyolitic volcanic ash. With the aid of a plane table and open-sight alidade, a small portion of the lake-bed area near Rocker was mapped; all distances were paced, but numerous checks assure a fairly accurate map.

The Age-Hardening Of Duralumin, Allison Richard Dyer

Bachelors Theses and Reports, 1928 - 1970

The development of wrought alloys of aluminum to which high strength and ductility can be imparted by heat treatment began with the work of Wilm and Claesser in Germany, 1905­-1911. During this time an alloy was developed which was later commercially produced in that country under the tradename of duralumin. The need for strong, light alloys for aircraft during the World War greatly hastened the development of duralumin.

Ammoniacal Sulphate Leach Of Ananconda Zinc Calcine Recovery Of The Zinc By Electrolysis., Authur Jewett Bovee Jr.

Bachelors Theses and Reports, 1928 - 1970

Zinc is produced from ores by two general methods, distillation and electrolysis.

The general principles involved in the electrolytic zinc process of today were known as far back as 1880. Difficulties encountered in purifying the solution for electrolysis and lack of suitable mechanical apparatus were the main reasons that such a long time elapsed before the process was used to produce zinc in commercial quantities.

Precipitation Of Gold, Silver, And Copper From Cyanide Solutions On Activated Charcoal., Rayworth Francis Howe

Bachelors Theses and Reports, 1928 - 1970

Charcoal has been known for a considerable length of time to have the property of recovering gold, silver, and copper from cyanide solutions of these metals. Quantita­tive data that may shed light on the mechanism of the re­moval of these metals is very limited except that char­coal in a form known as activated has the power to abstract gold and silver in considerable quantities from the above solutions.

The Effect Of Impurities On The Electrodeposition Of Zinc From Zinc Sulfate Solution Containing Antimony., Emmitt L. Klebba

Bachelors Theses and Reports, 1928 - 1970

It has been proven by research and years of experience, that before electrolytic zinc is possible, the electrolyte, as zinc sulfate solution must be prepared as pure as is economical. In other words, the ideal electrolyte must only be a solution of one metal - zinc. Every other metal and carbon must be excluded if good recovery and a firm deposit is to be obtained.

Alloys Of Lead And Tellurium, Ettore A. Peretti

Bachelors Theses and Reports, 1928 - 1970

Prior to the last few years little practical use was made of the element tellurium, which is obtained from gold and silver tellurides and from the slimes of electro­lytic copper refineries. Lately, however, more study has been made of its properties when alloyed with other metals. It was the purpose of this thesis to study the effects of the addition of tellurium to lead, particularly in small amounts.

Conodonts From The Quadrant Shales Of Montana, Don R. Cubbage

Bachelors Theses and Reports, 1928 - 1970

Conodonts have not been known to exist in Montana prior to the discovery of the specimens discussed and described in this paper. With this fact in mind, the author has endeavored to correlate the species of seven genera found in the Quadrant formation of Montana with similar micro-organisms from other North American areas.

Cost Of Engineering On Highway Projects, Walter John Shaffer

Professional Degree Theses

"It is customary for highway departments to set up certain finances in addition to the contract price to take care of engineering and slight overruns in the contract quantities. Generally a certain percentage of the contract price is used. The Missouri Highway Commission follow the practice of setting up 10% of the contract price to finance the engineering, contingencies, and slight overruns. The term "engineering" as referred to in this paper consists of the salaries and incidental expenses of the project engineer and his assistants, project office rent, and transportation. It will be noted that the preliminary survey work, blue …
