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.

Electro-Galvanizing From A Purified Ammonium Sulphate Leach Of Anaconda Zinc Calcine, Phillip J. Mischkot Jr.

Bachelors Theses and Reports, 1928 - 1970

Ever since the introduction of metal products into our civilization, especially those of iron and steel, man has been confronted with the problems of corrosion prevention. As the agents which are conducive to cor­rosion cannot be completely eliminated, it has been necessary for man to develop processes and materials that will retard the degeneration of the metals that are so important to our industrialized world.

Resistance Of Solid Inconel To Attack By Liquid Indium, David C. Hendra

Bachelors Theses and Reports, 1928 - 1970

The role of liquid metals in industry is rap­idly becoming of increasing importance. The phys­ical and chemical tendencies of metals in the liq­uid condition must be ascertained before a metal in this form can be put to practical usage. In very many stages of mineral processing and recovery, in molten-metal baths for temperature control on heat treating, and in several industries where heat transfer is an important aspect, metals may be at one time or another in a liquid condition.

The purpose of this thesis is to record and discuss the results of tests conducted, at the Montana School of Mines, in which pyrite concentrates from the Concentrator Department of the Anaconda Reduction Works, Anaconda, Montana, were subjected to the reducing effects of natural gas at elevated temperatures in an endeavor to produce iron in the metallic form.

A Microscopic Study Of The Ore Minerals From The Mines In The Northern Part Of The Zosell (Emery) Mining District, John P. Joyce

Bachelors Theses and Reports, 1928 - 1970

Any investigation of the many gold silver producing districts of Montana will necessarily include the name Zosell. The Zosell Mining District, often referred to as the Emery District, was never a major producer in the state; however, its location, history, type of deposit, and char­acter of ore, has drawn the interest of many prominent investigators of the mineral industry.

Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta

Bachelors Theses and Reports, 1928 - 1970

The exact upper boundary of the Devonian of Mont­ana has long been a controversy, as is true of the Dev­onian-Mississippian contact in many other localities. In an effort to delimit the upper Devonian, various paleontologic studies have been made, more especially in the southwestern part of the state.

Geology Of A Postulated Volcanic Vent Northeast Of Whitehall, Montana, C. H. Hewitt, H. D. Olson

Bachelors Theses and Reports, 1928 - 1970

The possibility of defining the roots of one of the volcanic sources of the Upper Cretaceous Livingston formation led to the detailed mapping upon an enlarged aerial photograph of a complexly intruded, folded, and faulted area about 10 miles northeast of Whitehall, Montana.

A Listing Of Montana Invertebrate Fossils And A Bibliography Of Montana Paleontology, Robert G. Ingersoll

Bachelors Theses and Reports, 1928 - 1970

The oldest system in which identifiable invertebrate fossils have been found is the Cambrian. The basal Cambrian formation found in Montana is the Flathead sandstone and quartzite of Middle Cambrian age. No fossils have been reported from this formation. Above the Flathead is the Wolsey formation composed of green fissile shale with sandy and limy members. This fossiliferous member of the Middle Cambrian is known in Northwestern Montana as Gordon, and in the Philipsburg quadrangle as the Silver Hill formation.

Mineralogy Of The Silver King Mine Of Park City, Utah, Pierce D. Parker

Bachelors Theses and Reports, 1928 - 1970

Except for the early work of Boutwell and Irving, little has been published on the geology of the Park City mining district. For this reason and because of the availability of a selected suite of ores from the Silver King mine of this area, this writer chose the mineralogy of the Silver King mine as a senior thesis for the de­partment of Geology of the Montana School of Mines.

The Construction Of A Ferromagnetic Torsion Balance, Elliott Willner

Bachelors Theses and Reports, 1928 - 1970

A Recommended Program Of Related Instruction For Electrical Apprentices, Andrew C. Luff

Masters Theses

Chapter I

Introduction

The Role of Apprenticeship

The institution of apprenticeship has been an important educational process since the beginning of history. Centuries ago trade skills were passed on from father to son, and from master to novice through an association whereby the craftsman taught the novice the skills of his trade. Down through history apprenticeship has flourished either in one form or another, and today it is an important part of the industrial system. Apprenticeship has developed in accord with industrial progress.

In order to avoid confusion, it may be well at the outset to designate the meaning of …

An Analysis Of Aviation Education In Senior High School Textbooks, Herbert E. Ellinger

Masters Theses

Chapter I

Introduction

Mankind has emerged from the Stone Age through the Ages of Iron, Steam, and Electricity to the present Air-Age. This latter age is characterized by man's utilization of air for travel, transportation, and communication.¹ It is common knowledge that the Air-Age has a number of social implications. More of our citizens are going abroad and more foreigners are visiting the United States than was possible, a few years ago, with slow moving surface transportation. Military planes now fly round-trips between continents without stopping. There are few places that are not within reach of air transportation. Hence, …

An Evaluation Of Necessary Elements For Desirable Industrial Arts Instruction In The Elementary Schools Of Utah, Lee W. Ralphs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An essential part of the elementary school curriculum is the creative activity program connected with it. Educators believe that the fullest development of the child can best be attained through a program which provides a series of well selected experiences and activities. At present education considers the whole child--his abilities, needs, and interests--as vital factors in the development of a good curriculum, instead of merely the concrete and formal subject matter. Recently there has been an expressed view, by administrators of elementary school systems and many authorities and industrial arts teachers, that there is a definite need for formulating an …

Canal Seepage Loss Investigations In The Lewiston Area, Utah, Robert V. Thurmond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With population, industry, and irrigation ever increasing in the arid west, there arises new and greater demands for water. Much of the water now urgently needed is lost as seepage from the many miles of canals in the western states.

Rohwer and Stout (18) have estimated that in the western states from one-third to one-half of the water diverted for irrigation is lost before it reaches the farmers' fields. Of these losses, seepage probably accounts for the greatest loss. It is reported by the Bureau of Reclamation (14) that, of the 14,600,000 acre feet of water diverted on 36 projects …
