The Solubilities Of Alkali Chlorides And Sulfates In Anhydrous Alcohols, Emmet Rudolph Kirn Jan 1930

The Solubilities Of Alkali Chlorides And Sulfates In Anhydrous Alcohols, Emmet Rudolph Kirn

Masters Theses

"A search of the literature for data on the solubilities of inorganic salts in various anhydrous alcohols will show that comparatively little work has been recorded. Most of the work has been done on salts in aqueous normal alcohols and practically all of this data concerns only methyl and ethyl alcohols. This information shows a wide divergence in results with different workers. Perhaps these differences in data may be attributed to an error in that the alcohols may not have been absolutely anhydrous, for even small traces of water greatly affect the solubility of the salts. Again, the methods of …

A Power Study Of A Laboratory Ball Mill, Frederick Clearman Jan 1930

A Power Study Of A Laboratory Ball Mill, Frederick Clearman

Masters Theses

"Ball milling practice in the ore dressing industry is largely empirical. Although many investigators have worked on various of its phases, the present operating methods are mostly a matter of cut-and-try, with the result that the industry is not guided by its underlying principles. Consequently, practice varies extensively with regard to nearly all conditions of operations. Even in neighboring concentrators such factors as speed, ball charge, and ore load differ in similar ball mills. Since fine grinding is continually becoming of more importance, and often accounts for thirty per cent of the milling cost, it is very necessary that a …

Laboratory Concentration Of The Missouri Iron Ores Of Iron Mountain And Pilot Knob, Strathmore Ridley Barnott Cooke Jan 1930

Laboratory Concentration Of The Missouri Iron Ores Of Iron Mountain And Pilot Knob, Strathmore Ridley Barnott Cooke

Masters Theses

"The purpose of this investigation was to ascertain whether the more important iron ores of Missouri would be amenable to beneficiation to produce high grade concentrates. In the southeastern section of Missouri are found many small deposits of high grade iron ores, and a few large deposits of comparatively low grade ore. The former consist chiefly of red and brown hematite and limonite ores that are in no need of beneficiation. the low grade iron orebodies are relatively large in extent, and, if they could be beneficiated successully [sic] and economically would be of value. Accordingly, the major portion of …

Salts In Tri-State Mill Waters: Their Ill-Effect On The Flotation Of Zinc And Their Removal, Warren Lincoln Howes Jan 1930

Salts In Tri-State Mill Waters: Their Ill-Effect On The Flotation Of Zinc And Their Removal, Warren Lincoln Howes

Masters Theses

"The application of the flotation process has become one of the greatest innovations in modern ore dressing. In a comparatively short span of years it has grown to be one of the most powerful tools of the ore dressing engineer. Flotation is particularly adapted for the recovery of finely ground mineral and has thus enabled the miner to open up enormous deposits of low grade, disseminated ores for profitable treatment. In conjunction with other methods, the process has raised the recovery in practically every ore dressing plant by the treatment of slimes which otherwise would go to waste, carrying valuable …

The Effect Of Occluded Air In Dry-Press Mixes, William Raymond Powell Jan 1930

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 Jan 1930

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 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, 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 …

Revision Of The Jefferson City Formation In The Rolla Quadrangle, James Shelley Cullison Jan 1930

Revision Of The Jefferson City Formation In The Rolla Quadrangle, James Shelley Cullison

Masters Theses

"The geology of the Rolla quadrangle was mapped by Lee in 1912. At that time all the dolomitic strata above the Roubidoux and beneath the Carboniferous formations in this area were placed in the Jefferson City. A more detailed study of the stratigraphy of the whole Ozark region by Ulrich has shown that some of the strata which had been included in the Jefferson City formation on lithologic grounds are not equivalent to the dolomites in the type section at Jefferson City, Missouri"--Introduction, page [1].

A Study Of The Electrolytic Determination Of Lead, Philip Hall Delano Jan 1930

A Study Of The Electrolytic Determination Of Lead, Philip Hall Delano

Masters Theses

"The electrolytic determination of lead is one of the most used methods, particularly for control work and where large numbers of analyses have to be run each day. The method is adopted because of its simplicity and because of the small amount of the chemist's time required. It is particularly suited for the determination of small amounts of lead. However, it has been noted that deviations from certain conditions produce results which vary widely from the actual amount of lead present, though results which check with each other may be obtained. Certain elements interfere with the determination and must be …

Producer Gas Practice In The Steel Industry, Horace Wilfred Hodges Jan 1930

Producer Gas Practice In The Steel Industry, Horace Wilfred Hodges

Professional Degree Theses

"The sources of energy for the industries are: 1. Water power; 2. coal, lignite, peat and Wood; 3. Natural and Artificial Gas; 4. Oil; 5. The Sun;s Rays; 6. The tides. The latter two sources may be eliminated from immediate practical use, owing to their cost and limited application. Therefore, the burden for many years will rest upon Water power, coal, gas and oil. We may also eliminate water power from the source of energy of the steel industry, due to the Mill's geographical location. Hence, for the near future, the steel industry's soul rests upon the production of coal, …

The Testing Of Steel For Wear By Abrasives, Thomas Evan Eagan Jan 1930

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 West Side Sewage Treatment Works Of The Sanitary District Of Chicago, John Edwin Mccauley

Professional Degree Theses

"Herein following is a thesis on the West Side Sewage Treatment Works of the Sanitary District of Chicago. I have endeavored to cover a large field in one thesis, but think is giving the material I have, the fundamental points have been covered. The local need of sewage treatment is so involved with county, state, Federal, and even International issues that to write solely of local conditions would be to leave out the main part of the story. So, in writing, I have tried to dover enough of the subject to give the historical facts along with the construction side …

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 …
