Engineering Practice In The Tri-State District, Richard John Stroup

Professional Degree Theses

"Mining operations of the zinc and lead deposits of Southwest Missouri, Southeast Kansas and Northeast Oklahoma forming what is known as the Tri-State District are peculiar in many ways. The 'old country' with its shallow gougings and more or less crude methods has practically passed; methods have been improved with the increased size of operations, and the Engineering Department has grown into an indispensable link in the mining operations of practically all the operating companies. But traditions often die hard. Many phases of mining operations are peculiar to this District alone, and likewise engineering practice has its peculiarities"--page 1.

Accident Prevention In Cement Plants, Edward Rees Abbott

Economic Geology Of Northern Angola, Artileus Vosteen Eulich

Professional Degree Theses

"Most of the mineral deposits have been known to exist for over a generation but efforts to mine them usually met with failure. The most signal discovery, that of diamonds, was made only in recent years. They are the only substance coming under the category of mineral which are being exploited on a large scale. Energetic efforts are being made to find petroleum in commercial quantities. There are still vast areas practically unexplored which if thoroughly prospected might lead to more discoveries. It is difficulty, however, for one who has prospected for two years in Angola without any particular success …

The Analysis Of Stresses And Design Of Multiple-Arch Dam, Guy Robert Scott

Bachelors Theses

"The so-termed: "Multiple", or "Scallop-Arched" dam, as its name implies, is one composed of a series of arches, either semi-circular or segmental in plan. These arches were first vertical but were later inclined downstream, when the engineers recognized the value of the weight of water in increasing the resisting moment. The thrust of these arches, due to the water pressure and the weight of the arch itself, is transmitted directly to the buttresses. There are numerous advantages to this type of dam over that of the gravity type"--Introduction, page 1.

Hydro-Electric Treatment Of Joplin-Miami Zinc Concentrate, David Francis Walsh

Masters Theses

"The Electrolytic Process is a process capable of almost unlimited mechanicalization. For obvious reasons it is more economic to treat high grade concentrates; yet, the extremely high grade concentrates are not essential. The Electrolytic Process can treat economically concentrates as low as 30.% zinc under certain conditions. It is significant that as the grade of concentrates offered for treatment is lowered, the treatment cost per ton of concentrates decreases for the Electrolytic Process; whereas, it will increase, as previously stated, for the Retort Process. It is seen then that the position of the Electrolytic Process is strengthened where lower grade …

The Solubilities Of Certain Inorganic Salts In Anhydrous Normal Alcohols, William Orval Keeling

Masters Theses

"An examination of the literature shows that extensive studies have been made of the solubilities of inorganic salts in aqueous, normal alcohols, but that little has been done in determining the solubilities in anhydrous alcohols. Northing was found of a systematic study of the solubilities of NaCl, KCl, NaN0₃ and KNO₃ in the lower alcohols over a fairly wide range of temperature. The author has made a study of the solubilities of the above mentioned salts in lower anhydrous normal alcohols at the temperatures 20°C, 25°C, 30°C and 40°C"--Introduction, page 1.

Conductivity And Ionization Of Certain Salts In Absolute Alcohol, Armin Brene Jewell

Masters Theses

"One of the most striking observations one makes in connection with the study of the conductivities of alcoholic solutions is their great similiarity [sic] to those of aqueous solutions with the exception that the values of the concentrations are very much smaller. The differences are rather of degree than of kind. It will be noted that as the temperature is increased the molecular conductivity increases and the fraction of salt decreases which is what would be expected by analogy"--Discussion, page 43.

The Reduction Of Zinc Oxide By Carbon, George August Zeller

Masters Theses

"In spite of the fact that the reduction of zinc oxide by carbon is the fundamental reaction upon which the pyrometallurgy of zinc is based, there is a decided lack of accurate knowledge concerning the mechanism of the reaction, the temperature at which it begins, and the effect of various factors upon the rate at which it takes place"--Introduction, page 1.

Boiler Feed Water Purification At The Gorge Power Plant, Akron, Ohio, Bernerd William Adams

Professional Degree Theses

"The conditions of operation at the Gorge Power Plant were such that raw water was used in all the boilers. The boilers were operated at an average of about one-hundred and seventy-five percent rating and considerable scale formed in the tubes of the boilers. It was evident that this caused a large loss in fuel and increased the expense of maintenance. It was necessary to employ a number of men to remove the scale. An investigation was made to determine as nearly as possible the loss caused by the use of impure water. After the investigation, an attempt was made …
