The Solubility Of Inorganic Salts In Carbon Disulfide: The Case Of Aluminum Bromide, Herman Henry Kaveler

Masters Theses

"Since about 1890, the interest in solubility has turned to a large extent to the investigation of the solubility of compounds in organic solvents. This has resulted in a great deal of work being done on the solubility of inorganic salts in non-aqueous solvents. As this mass of data steadily accumulated, the theoretical considerations of solubility and the ideal solution made rapid advances, as Hildebrand has pointed out. We express as much wonder over these theoretical advances as chemists did over the discover "that salts do dissolve in organic compounds". To add some useful data to that already accumulated on …

The Manufacture Of Liquid Oxygen And Its Use As An Explosive, Francis Kinlock Middleton Hunter

Professional Degree Theses

"Oxygen was first liquefied in 1877, but the first record of its use commercially as an explosive was in 1899 when part of the famous Simplon tunnel between Italy and Switzerland was driven with this explosive. Owing to the difficulties of storing and using this liquid, little more progress was made until the Great War, when Germany, forced to experiment with any promising explosive because of her rapidly diminishing stocks of Chilean nitrates, made considerable headway in the technique of using liquid oxygen...Since the War liquid oxygen explosives have been used extensively in France and Germany and to a lesser …

On The Permanent Growth Of Grey Iron, Walter Edward Remmers

Professional Degree Theses

"After making a survey of the available information on the subject of permanent growth in grey iron castings, it was found that very little definite information is available and such as is available does not seem to satisfy all conditions. As is perhaps generally known, grey iron castings withstand a growth in volume upon repeated heating and cooling, which growth is a permanent deformation and is not a function of the temperature co-efficient"--Review of Published Work, page 3.

A Preliminary Report On The Possibilities Of The Correlation Of Geochemical Data Relative To Oil Well Waters. A Report On The Oil Well Waters Of Greenwood County, Kansas, David Anderson Bash

Professional Degree Theses

"It is a known condition and a proven fact that vast quantities of oil and gas have been lost by the infiltration and encroachment of water in producing sands. The encroachment of water in the pay horizons has not only trapped underground oil locally and caused a great loss of production, but unless the water problem was successfully combated the amount of water entering the pay may increase to the extent of flooding an entire field. Water in an oil well so increases the lifting cost that many wells are abondoned [sic] before the normal recovery is reached"--page 2.

Relationship Between Temperature And Vapor Pressure Of Light Oils, William Orval Keeling

Professional Degree Theses

"There are a few data scattered through the literature on the vapor pressures of pure hydrocarbons, but the author has never seen a systematic study of the relationship between temperature and vapor pressures of complicated mixtures such as the various light oils encountered in refinery practice. Such data would be useful in designing equipment for distillation, steam stilling, vacuum distillation and in calculating heat balance, etc. An attempt has been made to link the vapor pressure of a light oil, at various temperatures, to the average boiling point of the oil"--Introduction, page 1.

The Role Of Geology In Prospecting For Lead And Zinc In The Tri-State District, William Ferdinand Netzeband

Professional Degree Theses

"The present generation has seen many changes in all phases of human endeavor, and the changes which have been made in the extraction of metals from the earth are not the least or these. The application of science to our industries has revolutionized many of them. Today quantity production in our factories is an accepted thing, and in the mines, application of the same principles has made possible the working of the low-grade copper deposits of Utah, Arizona, Chile and Belgian Congo. The mining industry has made use of almost all of the sciences in one form or another to …

Concentration Of Oxidized Lead Ores, Stephen Michael Burke Jr.

Professional Degree Theses

"In the pages of this paper an attempt is made to describe present methods of concentration and flotation of the oxidized ores of lead. The method employed is the presentation of the actual o operation of several mills which have been treating such ores during 1926 and 1927.

The plants described are representative operations and form some criteria for the performance of such ores under different conditions. In addition to those concentrators which are described, there are perhaps several small installations which are recovering lead from old mine dumps and tailings piles. It is difficult and almost impossible to obtain …

Methods Employed For Exploration And Development Of A Gold, Silver, Lead Property In The Idaho Springs District, Colorado, James Hopkins

Professional Degree Theses

"The Tonopah Colorado Leasing Company, a subsidary of the Tonopah Mining Company of Nevada, was organized in July 1922, for the sole purpose of carrying on the development and exploration of the Lombard Mine, situated in the N.E. corner of Clear Creek County, Colorado.

The former owners of the Mine were: The Continental Mines, Power and Reduction Company. This Company was held by the Seeman Investment and Finance Company. The property comprised 128 Mining Claims -- most of which were Patented. Other appurtenances of the Company comprised Mill Sites, Power Plant Site, Tunnel Sites and Ditch.

The Tonopah Colorado Leasing …

Fluorspar Mining And Milling In Southern Illinois, Henry William Hurst

Professional Degree Theses

"Fluorspar is fully as necessary a material in certain phases of steel manufacturing as the metal that enters the furnace. Without it, the basic open hearth practice probably would not have reached its dominant position among steel-making methods. Of the entire output of fluorspar, 80 to 85 percent is used in basic open-hearth and electric furnaces as a flux and detergent and there is today no known substitute.

The mining of the ore on a large scale requires extensive underground workings, much the same as is found in metal mines. Since high extraction can not be accomplished the milling of …

The Economics Of Engineering Testing, Gerald Franklin Rackett

Professional Degree Theses

"...It becomes the province of the engineer in his functions of designing and building the various units so prominent in our contemporary civilization, to guild with due regard for economic and mortal safety. To do these things he must have reliable data of the behavior and characteristics of those materials with which he works. The data can only be obtained by the systematic testing of engineering materials and the articulated units and fabricated structures that are built with them"--Safety, page 7-8.

A Study Of The Fluorspar Industry Of The United States With Respect To Its Future, Sidney Kincaid Reid

Professional Degree Theses

"The foregoing study shows that (1) there is ample reserve of fluorspar in the United States to take care of its requirements for many years, (2) if developed and scheduled on a production rate equal to at least seventy-five percent of the annual domestic requirements, (3) which will permit a sufficient increase in production rate in time of war to take care of increased wartime requirements"--Conclusions and Recommendations, page 83.
