The Effect Of Occluded Air In Dry-Press Mixes, William Raymond Powell

Bachelors Theses

"The effect of occluded air in clay mixes has recently become a subject of considerable importance especially since some of the defects occuring sic in dry-press ware, such as cracks and soft or granulated centers, have been either partially or wholly attributed to occluded air. According to this theory, the defects are due to the entrapping of air among the clay grains before compression, which, when the pressure is released, has a tendency to expand and cause a rupture in the bond. Also granulated centers have been explained by the fact that the entrapped air may act as a cushion, …

The Determination Of The Alumina Content In Diaspore And High Alumina Clays, W. D. Keller

Bachelors Theses

"The determination of the alumina in diaspore and kindred high alumina clays has been a problem which has attracted the interest of ceramists and chemists ever since a sample of Missouri diaspore was first sent for analysis to the laboratories of the Missouri School of Mines and Metallurgy in 1917...It is the writer's intention to review in this paper the various published methods for the determination of alumina in high alumina clays and to present a new indirect one that after some months' use in industrial practice, fulfills, in some measure at least, the need outlined above"--Introduction, page 1 -2.

The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Degree Of Pressure, Physical Character Of Mix Ingredient, And The Moisture Content Of The Mix, George Ava Page

Bachelors Theses

"In the manufacture of dry press brick, the final grinding and tempering of the clay is usually done in a dry pan. The next operation is forming the ware by means of applying pressure, either mechanical or hydraulic. The actual pressure that a brick is subjected to in a mechanical press has always been a question...The purpose of this investigation was to determine what effect would be imparted to the brick by varying the forming pressure and keeping the water content constant, and what effect would be imparted by varying the water content and keeping the forming pressure constant, on …

The Testing Of Steel For Wear By Abrasives, Thomas Evan Eagan

Professional Degree Theses

"The tests herein reported were conducted with the idea of finding a steel which would give improved wear as roll shells in the comminution of ores...Not only must the wear be considered, but also the physical properties. It is desirable to have a steel of such Tensile and impact values that no failure by breakage would occur until the shell was worn very thin. The ideal condition being to wear the shell down to zero thickness, but such cannot be accomplished"--Introduction, page 2.

The Lead And Zinc Deposits In The Sedimentary Rocks Of East Tennessee And Southwest Virginia, Joseph Hugh Reid

Professional Degree Theses

"In its geographic and geologic relations this area forms a part of the Appalachian province, which extends from the Atlantic Coastal plain on the East to the Mississippi lowlands on the West and from Central Alabama to Southern New York. All parts of the region thus defined have a common history recorded in its rocks, its geologic structure and its topographic features"--Geography, page 1.

The North Side Sewage Treatment Works Of The Chicago Sanitary District, Floyd Allen Gerard

Professional Degree Theses

"My aim in writing this thesis has been to give a clear and concise picture of the Plant, its construction, operating experiences, results and the need for sewage treatment. For this reason, I have incorporated much information, which, while not dealing directly with the subject in hand, is closely allied to it and forms a very necessary background. As the Sanitary District considers its actual operating results confidential, I have refrained from including them. Much useful information can be derived from a careful study of the photographs and drawings included"--page ii.

Oil And Gas Fields Of The Southern Gulf Coastal Plains Of Texas, Phillip Francis Martyn

Professional Degree Theses

"The purpose of this report is to furnish a general outline of the oil and gas fields of the Southern Gulf Coastal plain of Texas. To properly cover the subject, the report is divided into three major parts, the first part dealing with the present and past producing territory, the second part dealing with the factors influencing the producing territory and the third section relating to geology and its associated subjects covering the area as a whole"--Introduction, page 1.

Disintegration Of Ozark Plastic Fire Clay In The Drier, Elmer Francis Cirkal

Bachelors Theses

"During the procedure of testing Ozark Plastic Fire clay in 1928-29 a few of the test bars were unintentionally left in a laboratory drier and after some months it was found that these bars were decidedly disintegrated into a powder without any known special treatment...In order to properly investigate the cause of this phenomena it was decided to repeat the experiment under similar conditions so that no error could enter the investigation which would cause any deviation from the results previously obtained "--pages 1 -2.

The Effect Of Various Methods Of Grinding On The Physical Properties Of Unfired Dry Press Brick, Edwin Theodore Harvey

Bachelors Theses

"In the manufacture of dry press brick, the final grinding of the clay is usually done in a dry pan. This is especially true of fire brick made by the dry press method. It is logical to assume that different types of grinding machines will impart different characteristics to the ground clay mix, as regards the grain size variation and the shape of the grains, which in turn will have an effect on the properties of the brick. The purpose of this investigation was to determine what effect different types of grinding methods have on the physical properties of unfired …

The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Degree Of Pressure, Physical Character Of Mix Ingredient, And The Moisture Content Of The Mix, Ferdinand Frederick Netzeband

Bachelors Theses

"In February, 1929, the Dry Press Committee of the National Brick Manufacturers Association, in cooperation with the department of Ceramics of the Missouri School of Mines and Metallurgy, began several investigations relating to dry press ware. This Committee suggested a great number of possible investigations, and are now systematically proceeding along these lines. This investigation has for its object: (1) The transmission of pressure in the dry pressing of typical building brick and fire brick mixes as affected by the degree of pressure; and (2) As affected by the moisture content of the mix. this thesis contains a description of …

The Chromite Deposits Of Stillwater And Sweetgrass Counties, Montana, Uuno Sahinen

Bachelors Theses and Reports, 1928 - 1970

In writing this report, two objects were kept in mind, (1) to explain, if possible, the origin of the chromite deposits found in Sweetgrass and Stillwater Counties, and (2) to bring up to date all information on these deposits which had thus far been available.

The work done consisted of study of the rocks and ores of the area under the microscope, both as thin sections and as polished sections, practically all of which was done at the Montana State School of Mines, during the school year of 1928 - 1929.

The rock specimens and much information as to their …
