Insoluble Residues Of The Lower Mississippian Limestones Of The Madison Group, Fred G. Lines

Bachelors Theses and Reports, 1928 - 1970

The correlation of non-fossiliferous drill samples is one of the difficult problems that is en­countered in sub-surface stratigraphy. In order to truly correlate a formation, it must have some dis tinctive features and have an areal persistence of these features. These requirements are probably met best by limestone.

Sizing By Elutriation Of Finely Ground Quartz And Pyrite, Elmer C. Polson

Bachelors Theses and Reports, 1928 - 1970

Elutriation, as a means of sorting mineral particles, has received marked attention during the last fifteen years. Its use in the ceramics industry for the sorting of clays was recognized even before this.

Preparation And Properties Of Diethylene Glycol Fumarate Resin, Marian Sargent

Bachelors’ Theses

Fumaric acid, an unsaturated acid , condensed with diethylene glycol forms diethylene glycol fumarate, a resinous product of high molecular weight. This reaction is typical of condensation reactions. Since this is only the first step in making suitable finished products, the author wished to make a study of the preparation and properties of this condensation product and determine which of the known polymerizing agents were best suited for practical use.

The Cleaning Action Of Detergents And Soaps On Printer's Ink And Lubricating Oils, Daniel David Holzman

Bachelors’ Theses

During the past few years, industry has developed a steadily increasing interest in certain new types of synthetic organic compounds.

Industry devoted to the cleaning of textiles has found the removal of printer's ink and lubricating oils a tedious operation.

There has been developed and perfected a series of synthetic materials which successfully meet modern needs.

The detergents, in general, have some or all of the following properties: wetting-out, dispersing, emulsifying, penetrating, and cleaning.

There seems to be a need to investigate some of these new detergents for commercial cleaning purposes.

Phosphate Deposits In Western Summit, Wasatch, Salt Lake, Morgan, And Weber Counties, Utah, Alvin M. Hanson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphate deposits in the western United States have been the subject of considerable discussion in the last decade, and during the last few years much interest has been aroused in them. Phosphate was first discovered in this area in 1889, but it was not until 1906 that the United States Government took active interest in the study of these deposits. The investigation by the government of the occurrence of western phosphate was begun by Weeks and Ferrier (10), and later carried on by others. On December 9, 1908 the western phosphate reserve was created and many acres of land were …

Chromite Deposits Near Red Lodge And Silver Star, Montana, Edmond F. Smigel

Bachelors Theses and Reports, 1928 - 1970

The Red Lodge and Silver Star chromite deposits of Montana have stimulated much interest during periods of war. The Red Lodge deposit is 25 miles southwest of Red Lodge which is also the nearest railroad point. Several workings are scattered throughout the area, exposing lense-like ore bodies averaging 33% chrome oxide. Silver Star is a much smaller deposit 5 miles west of Silver Star, Montana, which is its nearest rail­road point. Lenses of chromite are exposed by pits and trench­es, which average approximately 36% chromic oxide.

Bachelors Theses and Reports, 1928 - 1970

It is known that there are large deposits of chromium ore in Stillwater and Carbon Counties in South-Central Montana. The late James F. Kemp of Columbia University, stated in 1928, that these were the largest chromium deposits in the United States and probably in the world, although they were not considered of commercial grade as compared with foreign ores.

Some Investigations On Quantitative Measurement Of Amalgamation, Charles Moore

Bachelors Theses and Reports, 1928 - 1970

Amalgamation is a process in which precious metals are collected by mercury. The exact way in which the mercury holds the other metals is not positively known. It is proba­ble that a series of intermetallic compounds form. Very little work has been done so far on the theory of amalgama­tion.

Stratigraphy And Paleontology Of The Eagle Formation In Montana And Adjacent Areas, Raymond Thompson

Bachelors Theses and Reports, 1928 - 1970

A conspicuous two hundred and fifty foot sandstone of central Montana, known as the Eagle Formation, constitutes part of the some five thousand feet of Cretaceous sediments in the state. It stands out in steep cliffs which stretch for many miles in the outcrop area from Wyoming to Canada.

Basic Information In The Granitic Rocks Of The Boulder Batholith, Clifford G. Sherwin

Bachelors Theses and Reports, 1928 - 1970

Dark fine grained basic masses of rock are found in nearly every part of the Boulder Batholith, these commonly being referred to as inclusions, segregations, autoliths, and various other names. The origin, distribution, and composition of the dark inclusions form the basis for this report.

Some Chromite Deposits In Madison County, Montana, Russell H. W. Chadwick

Bachelors Theses and Reports, 1928 - 1970

Chromite occurs in Madison County, Montana, in two areas, one three miles southwest of Silver Star, the other five miles southeast of Sheridan. The ore bodies are small, lenticular masses surrounded by metamorphosed sedimentary rocks of the pre-Cambrian Cherry Creek series. The ore was deposited from the hydrothermal solutions which serpentinized the surrounding metamorphic host rocks.

Measurements Of The Magnetic Permeabilities Of The Iron-Manganese Alloy System Prepared By The Methods Of Powder Metallurgy, O. Cihad Onbulak

Bachelors Theses and Reports, 1928 - 1970

Powder metallurgy is a branch of metallurgy which produces metallic compacts in their final forms by means of pressure and heat-treatment from the pow­ders. The products of powder metallurgy are being used in our daily lives quite often. For example, the tungsten wires in the electric bulbs to the silver-tin fillings of our teeth.

The Extraction Of Chromate Salts From Montana Chromite, Server Tasdemiroglu

Bachelors Theses and Reports, 1928 - 1970

In this thesis I have tried to determine the suit­able temperature, time and the amount of soda ash and lime needed for the calcining process. The leaching and purification tests were studied experimentally. The earlier process for making chromate from chromite was not the same as is used today. There­fore I have found it useful to put into this thesis the newest method for making chromate salts and their important uses.
