Disintegration Of Ozark Plastic Fire Clay In The Drier, Elmer Francis Cirkal Jan 1930

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 Jan 1930

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 Jan 1930

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 …


Constitution And Specific Gravity Of The Ternary Mattes Cu2S-Fes-Pbs., William Earl Lindlief, John Otto Groh Jun 1929

Constitution And Specific Gravity Of The Ternary Mattes Cu2S-Fes-Pbs., William Earl Lindlief, John Otto Groh

Bachelors Theses and Reports, 1928 - 1970

The constitution of the ternary mattes CU2S-FeS-PbS has never been completely investigated. Fulton and Goodner 1) have investigated the binary mattes CU2S-FeS, CU2S-PbS, PbSFeS and have shown that the three binaries show eutectics. There has been no attempt however to draw the complete ternary diagram. The following work is intended to be a contribution toward the completion of this diagram by first of all pointing out those mattes which separate on melting into two layers, and second by determining the specific gravities of mattes of different compositions.


The Effect Of The Cu:Fe''' Ratio Upon The Current Efficiency In The Electrolysis Of A Copper Sulfate Solution Containing Iron Sulfate, Joseph Thomas Roy, Francis Carroll Moran Jun 1929

The Effect Of The Cu:Fe''' Ratio Upon The Current Efficiency In The Electrolysis Of A Copper Sulfate Solution Containing Iron Sulfate, Joseph Thomas Roy, Francis Carroll Moran

Bachelors Theses and Reports, 1928 - 1970

It is a well-known fact that, in the electrolysis of a CuSO4 solution containing iron sulfate, using insoluble anodes, with the depletion of copper, the point is finally reached where the current efficiency becomes zero. This decrease in current efficiency is due to the oxidation of the ferrous sulfate to the ferric condition at the anode, by the oxygen liberated. The resulting ferric sulfate diffuses over to the cathode and there dissolves copper from the cathode according to the chemical equation Cu + Fe2 (SO4)3 = CuSO4 + 2FeSO4. This copper, which has …


The Chromite Deposits Of Stillwater And Sweetgrass Counties, Montana, Uuno Sahinen Jun 1929

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 …

Economics Of Supplying Electric Service To Downtown Areas Under Various Methods Of Distribution, Pericles P. Stathas Apr 1929

Economics Of Supplying Electric Service To Downtown Areas Under Various Methods Of Distribution, Pericles P. Stathas

Bachelors’ Theses

This thesis aims to present the problems involved in supplying electric service to downtown areas of high load density, with particular stress on the economies of rendering such a service. A considerable portion of the thesis is devoted to the new method of distribution, namely, the low-voltage A-C network.


A Study On Concrete Roads, Joaquin H. Hernandez Barreneches Apr 1929

A Study On Concrete Roads, Joaquin H. Hernandez Barreneches

Bachelors’ Theses

There is hardly an institution in existence that is as old and as useful as the road. In fact, it is so old and we are so used to its usefulness that we seldom think of its origin or its history. We take them more or leas for granted.

Florida Kaolin As The Chief Clay Ingredient For A Sanitary Ware Casting Body, Hugo Logan Harrod Jan 1929

Florida Kaolin As The Chief Clay Ingredient For A Sanitary Ware Casting Body, Hugo Logan Harrod

Bachelors Theses

"The purpose of this investigation was to utilize a large percentage of Florida Plastic Kaolin in a new sanitary ware casting body. Such a body, when worked out to be satisfactory, could be produced at a lower cost than those bodies being used in American plants at present. This particular plastic kaolin is available in large quantities in the southeastern portion of the United States. It is the intention of this work to substitute this American clay for the more costly imported English China Clay now being used in sanitary ware casting bodies"--Introduction, Purpose of the Investigation, page 1.


Bridge Survey Practice, R. B. Yule Jan 1929

Bridge Survey Practice, R. B. Yule

Electronic Theses and Dissertations

It is the intention in this paper to outline for general use the information that should be obtained in a survey for a proposed bridge in order that it may be designed with full knowledge of the conditions it must meet satisfactorily in service. The Manuals herein are written for conditions that exist in the Mississippi Basin and particularly the North Central States but will find general application with minor changes.
