Hardness And Electrical Resistivity Of Copper-Iron Powder Metal Compacts, Fred A. Foyle Jr.

Bachelors Theses and Reports, 1928 - 1970

Although powder metallurgical methods have been used for years to fabricate tungsten and platinum, very little scientific data have been recorded until the beginning of this century. A large percentage of all commercial production at present is based upon past practice rather than upon scientific knowledge.

Age Hardening Of Copper Antimony Alloys, William R. Stern

Bachelors Theses and Reports, 1928 - 1970

A large number of alloys of varying percentages of copper and antimony were prepared. These alloys were treated in various ways which might be expected to produce age hardening. The effect of cold working was studied in the range where the alloys were malleable.

The Electrodeposition Of Iron-Manganese Alloys, Raymond D. Magorien

Bachelors Theses and Reports, 1928 - 1970

An electrodeposition of an iron-manganese alloy was made from the same conditions determined by previous re­search. Various addition agents were experimented with in an attempt to produce better conditions for electro-deposition. It was found advantageous to add small a­mounts of sodium lauryl sulfate and ammonium sulfite to the electrolyte.

Geological Reconnaissance Of The Coldwater River, Mississippi, Pinckney Ronald Mabrey

Professional Degree Theses

"This report was the result of an assigment [sic] to make a geologic reconnaissance of the headwaters of Coldwater River in northwest Mississippi, on which a site for a flood control dam had been made. At the time of the last field work in November, 1940, the boring program for borrow areas and for foundation had been completed.

The Sardis dam on the Little Tallahatchie River, some 35 miles southeast of site for the Arkabutla dam had been recently completed, it being the first of several designed for flood control purposes in the Yazoo basin, Mississippi. This was a hydraulic …

Drainage As A Factor In The Development And Operation Of A Mine, Peter Paul Ribotto

Professional Degree Theses

"Peele's "Mining Engineers' Handbook" lists six of the more vital factors influencing the method of development and operation of a mine. These are (1) topography, (2) local geology, (3) location and mining of oreshoots, (4) haulage problems, (5) drainage, and (6) ventilation and safety. The purpose of this thesis is to provide a scheme for studying the drainage factor and to show how much a scheme works out in actual practice. Even the casual observer will note the interdependence and interrelationship among the factors listed. So closely tied together are they that the reasonable discussion of an item such as …

A Study Of The Flow Properties Of Concentrated Clay-Water Mixtures, William Joseph Smothers

Doctoral Dissertations

"The study of flow properties of many substances is of prime importance in varied industries. The ceramic industry is mainly concerned with these measurements on a relatively stiff ceramic body, i.e., one which contains only enough water to retain its shape after the deforming force is relieved.

Various types of instruments have been devised to measure flow properties in the so-called "true plastic range." Since the primary measurements were made on instruments of the transpiration type to devise the laws of viscous and plastic flow, it was felt that an instrument employing the flow of the plastic material through an …

Flotation Of A Complex Sulphide Ore Containing Tetrahedrite, James C. O'Dea, Lorimer W. Hoar

Bachelors Theses and Reports, 1928 - 1970

The ore investigated in this thesis is a zinc-copper-lead ore. Microscopic analysis of this complex sulphide ore showed it to contain pyrite_, sphalerite, arsenopyrite, galena, chalcopyrite, tetrahedrite, and covellite, with quartz as the gangue constituent.

An Attempt To Increase The Permeability And Porosity Of The Cut Bank Oil Sand By Treatment With Various Reagents, Donald H. Johnson

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation was to attempt to find some means of increasing the effective porosity and permeabil­ity of the producing sands of the Cut Bank Oil Field, with the hope that thereby the ultimate recovery of petroleum from this field may be increased. Although the percentage increase in production thus effected would undoubtedly be small, it would represent a substantial volume of petroleum in view of the great quantity of oil and gas present in this field.

Spectrographic Analysis Of Montana Limestones, Clifford A. Barkell

Bachelors Theses and Reports, 1928 - 1970

Spectrographic analysis of limestones as a possible method of correlation of geologic formations is an altogether new line of investigation. As far as known the only previous work consists of a few analyses made by Fred Lines in his bachelor thesis work at Montana School of mines in the spring of 1942.

Permeability And Porosity Studies Of The Cut Bank Oil Sand, Wesley Edward Davis

Bachelors Theses and Reports, 1928 - 1970

In studying the Cut Bank field and its numerous wells, it is found that dry holes are surrounded by producing wells, and also that the field as a whole is very irregular; water, oil, and gas zones in many cases following no definite pattern. In some instances, this phenomenon may be due to the lensing and thinning of the producing sands, but it is evident that this is not the only factor. There­fore, the controlling factors must be porosity and permeability.

Missouri Super Duty Refractories And Their Probable Application For Blast Furnace Linings, Charles Alfred Freeman

Professional Degree Theses

"The use of Missouri Super Duty Refractories in steel plant service is not new, although their use in blast furnace service has been limited chiefly to stove installations. They have, however, been used in a sufficient number of places where severe operating conditions exist, so that they are a definitely known quantity and they have consistently shown much longer service under conditions of high temperatures and contact with slag and molten iron. One outstanding comparison of the service which these brick give over ordinary first quality brick is the bottom of a malleable iron furnace. Not first quality refractory has …

Bituminous Construction With Sandstone Aggregate Johnson County Project, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

On April 25th detailed notes wore made on each station of this project, and it was decided that samples should be taken to represent each type of surface on the project. Seventeen samples ware selected as representative of the different types of mixes, and on May 6th and 7th samples fifteen inches in diameter were drilled from this project. These samples were selected to represent the variations in gradings and bitumen content.

A Study Of Methods For The Purification And The Removal Of Color From Trinitrotoluene Wash Waters, William Wilson

Masters Theses

"Symmetrical Trinitrotoluene is stable in the presence of moisture, but the nonsymmetrical trinitrotoluenes permit replacement of a nitro group with the formation of a nitrated cresol and nitrous acid. Nitrated cresols form salts similar to the picrates. To avoid these nonsymmetrical trinitrotoluenes the Ordinance Department, U. S. A., requires that Grade I trinitrotoluene have a solidification point of at least 80.2⁰C.². Numerous methods for purifying the crude trinitrotoluene and others for separating the nitrotoluenes have been suggested"--Introduction, page 1.

Aircraft Quality Casting Standards, Robert Katz, Robert Bolin , Depositor

Robert Katz Publications

These standards are to be used in connection with the Handbook for Instructions for Aircraft Designers, 8^th Edition …

In the radiography of aircraft castings, markings appearing on the film may be attributed to either the condition of the castings examined, or to some details of the radiographic process entirely unrelated to the quality of the castings, These latter patterns must be recognized and related to the radiographic process so that sound castings will not be unnecessarily rejected. Radiographs must be carefully compared with the surface irregularities of the casting they represent before an attempt is made to …
