Electroplating Of Chromium, Nickel And Copper Upon Titanium, Stanley O. Fong

Bachelors Theses and Reports, 1928 - 1970

Recently, there has been a great amount of research work done on the metal titanium. Since it is a light weight metal, with unusual strength and good resistance to corrosion, it may be a possible substitute for aluminum and magnesium alloys, or steel.

An Attempted Determination Of The Approximate Chemical Composition Of The Livingston Volcanics By The Fused Bead Technique, Robert D. Geach

Bachelors Theses and Reports, 1928 - 1970

Many fine-grained igneous rocks, basaltic and felsitic in character, are difficult to classify. In numer­ous cases, it is impossible to classify these types of rocks by quick methods of identification. It was hoped at the beginning of this study that refractive indices of glasses formed by quick artificial fusion of samples from selected suites of igneous rocks would show a close cor­relation in chemical composition.

Dispersing Agents In The Pipette Method Of Soil Analysis, Eugene W. Price

Bachelors Theses and Reports, 1928 - 1970

For many years the study of sediments has been a major problem in the field of geology. Especially is this true of the branch of sedimentology known as grain-size distribution. Throughout the years many classical experiments have been performed and procedures evolved from them, all with the purpose of a better and easier determination of the grain-size distri­bution of fine sediments, particularly the clays.

An Early Tertiary Stream Channel Between Fish And Pipestone Creeks, Ten Miles West Of Whitehall, Montana, Henry D. Olson

Bachelors Theses and Reports, 1928 - 1970

Driving between Butte, and Whitehall, Montana, on highway U.S. 10S, one observes an interesting phenomenon in the lower end of Little Pipestone Creek canyon. One side and the bottom of the canyon is cut inthe hard igneous rocks of the Boulder Batholith, and the other side of the canyon is made of unconsoli­dated sand, gravel, and cobbles.

Test 472: John Deere 60, Nebraska Tractor Test Lab

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: John Deere 60

TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear.

This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.

A Study Of The Effect Of Jointing On The Blasting Of Granite, Graniteville, Missouri, Avery Ala Drake

Masters Theses

"Purpose of investigation: The purpose of this investigation is to attempt to determine the influence that joints exert upon the blasting of granite and if joints are induced by blasting. The problem grew out of an explosive evaluation project that was conducted by the Mining Department, Missouri School of Mines. In late May 1950, the project was moved into the granite area near Graniteville, Missouri. It became apparent upon study of this area that the jointing would have certain effects upon the results obtained. Dr. J. D. Forrester, Chairman, Department of Mining Engineering, Missouri School of Mines, Rolla, Missouri, suggested …

The Occurrences Of Non-Metallic Minerals In Montana, Samuel T. Mitchell

Bachelors Theses and Reports, 1928 - 1970

This thesis is essentially an abstract of the literature concerning occurrences in Montana of minerals with a non-metallic luster. The dis­cussions give a general description of the occurrences of minerals as reported by the various references, but is not complete as less than 40 percent of the non-metallic minerals known to exist in Montana are discussed.

Microfauna Of The Colorado Shale In The Sunburst Dome Area, Montana, Merle W. Emmert

Bachelors Theses and Reports, 1928 - 1970

It has been hoped that a micropaleontological study of the shales of the Upper Cretaceous Colorado Group in northern Montana would reveal certain faunal zones which would serve as markers in an otherwise drab, undifferentiated, 1800 feet of grey, fissile shale. This paper presents the results of a study of the microfauna in certain samples from this shale in the Sunburst Dome area north of Shelby, Montana.

The Elkhorn Mine Of Jefferson County, Montana, David D. Walker

Bachelors Theses and Reports, 1928 - 1970

In 1901, after yielding metals valued in excess of five million dollars, it was considered worked out. Since that time the mine has passed through the hands of several own­ers, none of whom have failed to realize a profit from it. Although at no time since its zenith did it ever regain its once great production, it did provide a livelihood for those who worked it. Now with the American Smelting and Refining Company interested in it, perhaps it will once again become an important producer.

Sulphidizing Of Cerussite, Emil A. Kovacevich

Bachelors Theses and Reports, 1928 - 1970

The oxide minerals, such as cerussite, are not as amen­able to flotation as the sulphide minerals. Sulphidization is the usual means used today to increase the recovery of an oxide flotation; however, sulphidization under the most ad­vantageous conditions does not yield very satisfactory re­coveries.

The Groundwater Of The Area North Of Flathead Lake, Montana, Frederick M. Hilpert

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation is to determine the reasons for the ground water variations in the area north of Flathead Lake, Montana. Several methods were used in pursuing this investigation. Hydrographs were made of the various wells showing the season to season change as well as the year to year variation.

Faunal Studies Of The Lower Jefferson Limestones, James L. Eymann

Bachelors Theses and Reports, 1928 - 1970

The exact geologic age of the Jefferson limestone in Montana has not been definitely determined, other than it is probably of upper, but possibly in part of middle Devonian age. Although not of immediate or apparent economic importance, the determination of the exact age of the Jefferson limestone may be of much value in connection with the discoveries of large quantities of oil in Devonian strata in the northern Great Plains and, in particular, with the extensive deep drilling in northeastern Montana which is anticipated during the summer of 1951.

A Mineralogical Investigation Of Some Montana Hydrobiotites, John W. Baker

Bachelors Theses and Reports, 1928 - 1970

Vermiculite is one of the most recent important nonmetallic minerals to be exploited for use in the industrial world. For this reason, the fund of knowledge relating to this mineral is rather limited. This paper represents the results of laboratory studies that were undertaken to contribute data to this fund of knowledge.

Differential Thermal Analysis Of Some Carbonate Minerals, Paul L. Vandeveer

Bachelors Theses and Reports, 1928 - 1970

Thermal analysis is a relatively new method of determining the general composition of certain mineral substances. As is demonstrated by much of the literature previously written, clays and carbonates are especially adaptable to this method. The full importance of the method is not as yet realized, but it is rapidly approaching that point.

The Gallium-Indium Constitutional Diagram, Richard E. Gaffney

Bachelors Theses and Reports, 1928 - 1970

Because of the discrepancy as to whether there is solid solubility in the gallium-indium system, and the fact that no alloys with less than 1% indium were ever investigated; the possibility of solid solubility in either or both ends of the diagram was not overlooked. According to Hume-Rothery, two alloys with the same relative positions on the Periodic Chart should have about the same alloying habits.

Electrowinning With Amalgam Electrode, Ralph V. Anderson Jr.

Bachelors Theses and Reports, 1928 - 1970

Amalgam Metallurgy, a relatively new expression in the technology of metal extraction, was first chosen to describe certain new processes developed at the Duisburg Copper Works in Germany. The idea of using mercury, a costly and poisonous metal, as an intermediate in heavy chemical industry and in polarography are of recent origin; with the exception of a series of patents of little signif­icance and occasional comments in the literature, the work is hardly known.

Metal Production From Ore Deposits In Different Host Rocks In Montana, Robert F. Gale

Bachelors Theses and Reports, 1928 - 1970

It is known that many different kinds of rocks serve as host to the ore deposits of Montana, but the relative importance of each of these kinds of rock as a host for ore deposits has never been described in any published report.
