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

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 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.

A Report On Drill Steel Wear At Isle Royale Mine, Houghton, Michigan, James Joseph Dowd

Professional Degree Theses

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 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 …

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 Preparation Of Zinc Chloride From Smelter Waste, Victor K. Fischlowitz

Masters Theses

"Interest in the matter of recovering zinc from residual material attaches through the value of a practical method of recovery consistent with commercial operations. The material used in this work at the Missouri School of Mines and Metallurgy was supplied by one of the large chemical firms of Saint Louis"--Introduction, page 3.

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.

The Copper Deposits Of Shannon County, Missouri, John Hyer Bowles, Lewis Ely Davidson

Masters Theses

"The object of this report has been three-fold. First, it has been deemed necessary to discuss the general geology of the area about Eminence, showing the distribution and character of the different formations. The distribution is shown on a topographic map of the Eminence Quadrangle...In the second place, it is intended to give a detailed account of the history, development, and extent of mining operations in Shannon county, with the amounts of production and the occurrence of the ore. The third object of this report is to develop a probable theory for the genesis of the ore, and to discuss …

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.

An Experimental Study Of The Cathode Fall In Helium And Argon With Wire Cathodes, L. G. Raub

Papers from the University Studies series (University of Nebraska)

It was recognized rather early in the study of the phenomena of discharge of electricity through gases that the ordinary laws of conduction as found in solid and liquid conductors are not applicable to gases. It was shown by Zeleny and independently by Child that Ohm's law by no means represents the distribution of potential between electrodes in an ionized gas, but that the potential gradient is large in the vicinity of the electrodes, and not uniform throughout the space between them. When the pressure of the gas surrounding the electrodes is reduced to one or two millimeters and a …

A Study Of "Black Liquor" From Soda Pulp, Chen Chi Pan

Electronic Theses and Dissertations

At the present time, practically all of the soft easy bleaching pulps used for the manufacture of high class book, magazine, general printing and cheaper writing paper are made by the Soda Process. Although the sulphite and mechanical process and to a less extent the Sulphate Process predominate, the Soda Pulp is remarkably well adopted for producing Pulp Fibres from any kind of wood or other fibrous material, no matter how resistant to chemical attack it may be.

Up to 1876, black liquor was run to waste. But since the River Pollution Act, it is treated to recover the soda, …
