The Pre-Jurassic Surface Of Montana., G. Fay May 1939

The Pre-Jurassic Surface Of Montana., G. Fay

Bachelors Theses and Reports, 1928 - 1970

It has long been known that, prior to the deposition of Jurassic sediments, Montana was subjected to an intensive period of erosion. Mention of this may be found in numerous reports, especially those dealing with western Montana.


Electrolytic Manganese, George T. Derana May 1939

Electrolytic Manganese, George T. Derana

Bachelors Theses and Reports, 1928 - 1970

The production of metallic manganese by electrolysis is of potential value for the recovery of this strategic metal from domestic deposits. These deposits are largely unsuitable for the production of ferromanganese, but they are amenable to low-cost leaching processes.


Igneous Rocks Of The Jardine And Crevasse Mountain Mining Districts., Ray E. Gilbert May 1939

Igneous Rocks Of The Jardine And Crevasse Mountain Mining Districts., Ray E. Gilbert

Bachelors Theses and Reports, 1928 - 1970

It is surprising to learn that so large a variety of igneous rocks is present in the Jardine and Crevasse Mountain mining districts, a region that is generally thought of as consisting principally of schists.


The Age Hardening Of Copper With Manganese Silicide., Gordon A. Davis May 1939

The Age Hardening Of Copper With Manganese Silicide., Gordon A. Davis

Bachelors Theses and Reports, 1928 - 1970

The increase in hardness is attributed to the manganese silicide being precipitated from solid solution and deposited between crystal planes. The subsequent softening which occurs on prolonging the period of reheating is believed to be due to an agglomeration of the dispersed hardening agent.


Geology Of The Golden Sunlight Mine And Vicinity, Roy H. Earhart May 1939

Geology Of The Golden Sunlight Mine And Vicinity, Roy H. Earhart

Bachelors Theses and Reports, 1928 - 1970

The Golden Sunlight Mine is in the northern part of the Cardwell mining district on the eastern slope of a small range that rises by a series of benches to an elevation of 7,200 at a point five miles east of the town of Whitehall in Jefferson County.


Powder Metallurgy, Cecil R. Waldron May 1939

Powder Metallurgy, Cecil R. Waldron

Bachelors Theses and Reports, 1928 - 1970

The metal powders may be produced in a number of different ways. In metals where the intercrystalline material is brittle enough, they may be ground in a ball mill or eddy mill. The fineness of such a powder is more or less controlled by the grain size of the original metal.

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott Mar 1939

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …

Geology Of A Portion Of The Bull Mountain Range Jefferson County, Montana, Thomas A. Greene Jan 1939

Geology Of A Portion Of The Bull Mountain Range Jefferson County, Montana, Thomas A. Greene

Bachelors Theses and Reports, 1928 - 1970

Work was first done on a known section, the south Boulder Section, in order to familiarize the student with the formations. Most of the area was mapped by plane table and telescopic alidade, general features being surveyed by automobile traverse and a pacing traverse.


A Report Of The Geology Of The Golden Sunlight Mining District, Roy A. Mccready Jan 1939

A Report Of The Geology Of The Golden Sunlight Mining District, Roy A. Mccready

Bachelors Theses and Reports, 1928 - 1970

This paper is a report of a geological survey made of an area of approximately fifty square miles lying Northeast of Whitehall, Montana, in the region of the Golden Sun­light Mine. The survey was made by a field party consisting of twenty-three members of the senior class of the Montana School of Mines.


South Moccasin Kaolin Deposit, Walter Everly Jan 1939

South Moccasin Kaolin Deposit, Walter Everly

Bachelors Theses and Reports, 1928 - 1970

Kaolin has never been considered an important economic mineral in Montana. Deposits of Kaolin in this state are not described in the literature and apparently very few deposits have been found.


Test 319: M-M Twin City Model Utu (Gasoline), Nebraska Tractor Test Lab Jan 1939

Test 319: M-M Twin City Model Utu (Gasoline), Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.

All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.

Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

3 Brand New Farmalls, Nebraska Tractor Test Lab Jan 1939

3 Brand New Farmalls, Nebraska Tractor Test Lab

Nebraska Tractor Tests

When you slip into the large and comfortably cushioned seat of a Farmall-H or a Farmall·M nd rest your hands on the large, automobile type steering wheel. right away you feel at home. As your left foot just naturally finds the clutch pedal and you put the tractor into gear you begin to get the feeling that here is a tractor that is as easy 10 drive as the family car. And as you give it the gas (gasoline. distillate or kerosene). and let in the clutch, you get the thrill which comes with the realization that here, under finger.tip …

Design Study Of A Three Span Continuous Tied-Arch Bridge, George Perry Steen Jan 1939

Design Study Of A Three Span Continuous Tied-Arch Bridge, George Perry Steen

Masters Theses

"In this study of the continuous tied-arch bridge, having one main span and two equal side-spans, the following items are endeavored: (1) To set up the total internal work equations and to find the values of the unknown forces or redundants. (2) To compute to maximum moments for design and to complete the design of the super-structure for one bridge. Details, such as the gusset plates, rivets, connection angles, etc., are not designed; the effect of such being allowed in the design for dead load as a certain per cent for details. (3) To set up hypothetical conditions for other …
