Flotation Tests On A Table Sludge From The Golden Rod Milling Company At Tar River, Oklahoma, William H. Kamp Jan 1921

Flotation Tests On A Table Sludge From The Golden Rod Milling Company At Tar River, Oklahoma, William H. Kamp

Professional Degree Theses

"The purpose of this experimental work is to give to the operators of the Joplin District some facts concerning the possibilities of flotation in their district. An attempt will be made to show that high-grade concentrates can be made economically; also that the usual gravity concentration. It is believed that the oil and reagent used will not put a prohibitive cost burden upon the operators. It is, of course, realized that flotation concentrates of any zinc tenor bear a penalty because of the fineness of the product"--Introduction, page 3.

The Heat Treatment Of Cast Steel, Fred Grotts Jan 1921

The Heat Treatment Of Cast Steel, Fred Grotts

Professional Degree Theses

"Owing to many difficulties reported from the battle fields of France also from many sections of the United States, Mexico, Africa and South America relative to the functioning of the "Caterpillar" track an intensive research was begun early in the spring of 1919 to develop or perfect a material that could be made into intricate forms and which would have such physical properties as would withstand to a maximum degree, the abrasive action of rock and sand while at the same time having a high tensile strength and resistance to shock. A further requisite was that this material must be …


The Manufacture Of Sulphuric Acid By The Chamber Process At Isabella, Tennessee, Albert Leo Trent Jan 1921

The Manufacture Of Sulphuric Acid By The Chamber Process At Isabella, Tennessee, Albert Leo Trent

Professional Degree Theses

"As the regions surrounding the smelteries are growing more densely populated, the companies operating in these districts find if necessary in many cases to take care of their waste gases which are injurious to the surrounding vegetation and thereby avoid many expensive lawsuits and claims from the land owners in the district...The smelters at once began to look around for some method of taking care of their fumes...The companies then began to install the more expensive process of handling their fumes by adding a sulphuric acid plant to their smeltery. This is very expensive to install but is not only …


Investigations To Determine A Possible Source Of The Carboniferous Sandstone Of The Ozark Region, John Hyer Bowles, Lewis Ely Davidson, William Ferdinand Netzeband Jan 1921

Investigations To Determine A Possible Source Of The Carboniferous Sandstone Of The Ozark Region, John Hyer Bowles, Lewis Ely Davidson, William Ferdinand Netzeband

Professional Degree Theses

"In preparing this thesis the object has been to determine, by comparisons, a possible source of the Carboniferous sandstones. It is perfectly obvious that the material came from some older formation. Considering all the possible sources from which the Carboniferous sandstone could have originated, we, have the Pre-Cambrian igneous rocks of the St. Francois Mountains, the basal Cambrian sandstone or the La Motte formation, the Roubidoux formation (chiefly sandstone), and the St. Peter formation (essentially sandstone)"--Introduction, page 4.


The Mexican Oil Fields, Raul Chavez Jan 1921

The Mexican Oil Fields, Raul Chavez

Professional Degree Theses

"Owing to the large area involved in this paper it is proposed to give only briefly the history, geology and development of the oil industry in Mexico, as well as to discuss in a general way the present oil legislation which has brought so much comment in the papers and has raised to much diplomatic trouble between the Mexican and United States Governments. This discussion is therefore of a brief nature and only the most culminant features and details of the subject in mind are here treated. The information and data here given were accumulated during personal examination of the …


Geologic Conditions Affecting The Accumulation Of Oil And Gas In The Beggs District, Oklahoma, John Charles Miller Jan 1921

Geologic Conditions Affecting The Accumulation Of Oil And Gas In The Beggs District, Oklahoma, John Charles Miller

Professional Degree Theses

"It is generally accepted that there is lack of parallelism between surface and subsurface beds and between the productive sands in the Beggs District, a condition similar to that which obtains in the Cushing Field. The explanation of this condition as given on page 31, Bulletin 658, U.S. Geological Survey, is: 1) The difference in resistance to compression of the hard and soft beds of which the formations of the Cushing Field are composed; 2) The lenticular form of the Bartlesville sand (the equivalent of the Glen; Gas of Morris pool); 3) One or more unconformities between surface beds and …


Mine Surveying In The Missouri Coal Fields, Edgar C. M. Burkhart Jan 1921

Mine Surveying In The Missouri Coal Fields, Edgar C. M. Burkhart

Professional Degree Theses

"The mines surveyed and included in this thesis are certain mines in the foremost and second largest producing counties in the state, namely Macon and Adair county. This thesis also includes surveying at one mine in Randolph County ... The mines included in this thesis operate mainly in the Bevier bed. This seam contains an average of 41 inches of coal in Adair County and is somewhat thicker in Macon and Randolph County. All mines in the Bevier bed are operated on the room and pillar system of mining with about 50 to 60 percent extraction in Adair County and …


Investigations On Oklahoma Chats, Homer Chalmers Kerr, August Francis Delaloye Jan 1921

Investigations On Oklahoma Chats, Homer Chalmers Kerr, August Francis Delaloye

Bachelors Theses

"That the tailings piles of the Joplin and the Oklahoma zinc mining fields contain zinc in commercial quantities is a known fact. Realizing this fact, a number of experiments were performed to determine whether or not this zinc could be extracted. The chats for this work were obtained from the Fort Worth Mill at Pitcher, Oklahoma"--Introduction, page 1.

Glucose From Corn Cobs, Barney Nudelman Jan 1921

Glucose From Corn Cobs, Barney Nudelman

Masters Theses

"The efforts of American chemists in recent years have been devoted largely to the utilization of our waste products...Corn cobs offer a particularly inviting field for research along this line on account of the large supply of cobs available and the variety of substances obtainable from them. One of the leaders in this branch of investigation is Dr. F. B. LaForge of the Chemistry Division of the Bureau of Agriculture, who has contributed numerous papers on the subject. In one of these, in collaboration with C. S. Hudson, he describes, among other things, the preparation of glucose, but recognizes the …

The third object of this report is to develop a probable theory for the genesis of the ore, and to discuss …


Furfural (Furfuraldehyde) And Some Of Its Derivatives, Marion Smith Badollet Jan 1921

Furfural (Furfuraldehyde) And Some Of Its Derivatives, Marion Smith Badollet

Masters Theses

"In the spring of 1919 the Eastman Kodak laboratories suggested to the chemistry department of the Missouri School of Mines and Metallurgy that experiments on small-scale production of furfural be undertaken. After a series of experiments a small amount of this product was made and a report was given before the American chemical Society at St. Louis in April 1920. The furfural prepared at the Missouri School of Mines and Metallurgy was sold to the Eastman Kodak laboratories. Within recent years very little experimental work has been done on furfural. It commands a high price as only small amounts are …


The Action Of Nitrogen Trioxide On Pinene, Ernest Wayne Rembert Jan 1921

The Action Of Nitrogen Trioxide On Pinene, Ernest Wayne Rembert

Masters Theses

"The action of nitrous acid on pinene was first studied by Pesci and Bettelli in 1885. they obtained an oil, which, when treated with NH₄OH and steam distilled gave a product of the formula C₁₀H₁₆NO₂. At this point the investigation was discontinued. It is the purpose of this work to show the true mechanism of the reaction and also to establish the formula and nature of the products obtained"--Introduction, page 3.


Characteristics Of Bacillus Influenzae, Georgena Josephine Clarke Jan 1921
