Alloys Of Lead And Tellurium, Ettore A. Peretti

Bachelors Theses and Reports, 1928 - 1970

Prior to the last few years little practical use was made of the element tellurium, which is obtained from gold and silver tellurides and from the slimes of electro­lytic copper refineries. Lately, however, more study has been made of its properties when alloyed with other metals. It was the purpose of this thesis to study the effects of the addition of tellurium to lead, particularly in small amounts.

Cost Of Engineering On Highway Projects, Walter John Shaffer

Professional Degree Theses

"It is customary for highway departments to set up certain finances in addition to the contract price to take care of engineering and slight overruns in the contract quantities. Generally a certain percentage of the contract price is used. The Missouri Highway Commission follow the practice of setting up 10% of the contract price to finance the engineering, contingencies, and slight overruns. The term "engineering" as referred to in this paper consists of the salaries and incidental expenses of the project engineer and his assistants, project office rent, and transportation. It will be noted that the preliminary survey work, blue …

Foundations For Aquatic Oil Wells, Henry Emmett Gross

Professional Degree Theses

"During the past decade, man has found the courage to drill for oil at those forbidding locations which were made inaccessible by several feet of water. Some of the major fields of the world have been developed by this new manner of work, and others might have been added had the stage been set for the play. The most spectacular marine oil field development occurred along the Santa Barbara Coast of California from 1929 to 1931. It was the writer's good fortune to have been an assistant to Mr. Hans E. A. Gude, the field engineer of Pacific Western Oil …

Fuller's Earth In Southeast Missouri, Willard Farrar

Professional Degree Theses

"Recent work, (1933-34) in southeastern Missouri by the Missouri Geological Survey has shown that deposits of bleaching clay occur in the Porters Creek formation of Tertiary age. Various localities in Scott and Stoddard counties are described, in which favorable conditions for development exist. The method of testing the clay for bleaching power is treated briefly. Suggestions are offered in regard to prospecting, mining and milling"--Abstract, page 5.

Problems In The Cement Industry, William Alonzo Mccanless

Professional Degree Theses

"The major problem of the cement companies is the matter of marketing the product in sufficient quantities and at a price which will return a profit; however, there are some other problems that are of great interest to the engineers, i.e., the interest in the economics of cement based largely on its effect on the cost of contemplated structures"--page 1.

Efficient Management Of Highway Projects Under State Administration, From The Point Of View Of The Project Or Resident Engineer, Jean Paul Bryan

Professional Degree Theses

"Efficiency in any project is an admirable attribute. It is even more than admirable in an undertaking designed for the spending of the taxpayer's money in which the lack of this trait is so liable to be interpretated [sic] as graft. It is necessary. After some eight years of connection with highway construction, a familiarity with inefficiency in the management of high projects under state construction is sufficient excuse, we believe, to warrant a dissertation of the opportunities for the practice of efficiency by those in direct charge of these project - the Project Engineers or the Resident Engineers, as …

A New Theory Of The Spalling Of Fireclay Products With Relation To Thermal Expansion, Robert Legrande Stone

Bachelors Theses

"There is one factor that is responsible for much of the failure of refractories in furnaces and other metallurgical processes and boilers, namely spalling. Many times this action has been the cause of roofs to cave in, side walls to slump, and bungs to fail. Consequently it is a factor that is of utmost importance. The erosion and slag effects are also of greatest importance to refractory stability. Spalling, as referred to refractories, is defined as the breaking or crushing of the unit due to thermal, mechanical, or structural stresses, presenting newly exposed surfaces of the residual mass. Taking the …

The Effects Of Sodium, Barium And Calcium Chloride Upon The Physical Properties Of A Whiteware Body, William Newton Coffman

Bachelors Theses

"The wide spread use of American kaolins and ball clays has been frowned upon by the majority of white-ware manufactures because the product resulting from their use in most cases has a color which is inferior to ware produced from English raw materials. This inferior color is generally attributed to the presence of a small amount of iron in the American clays. If some inexpensive chemical addition could be made which would eliminate the iron stain or in some way mask it, a wider market could be found in the white-ware industry for the domestic clays. One way to eliminate …

The Equilibrium Relations Of Nickel Sulfide With Copper And Sodium Sulfides, Walter A. Hamilton

Bachelors Theses and Reports, 1928 - 1970

The equilibrium relations of many of the metallic sulfides have long been a source of scientific and commer­cial interest, of particular interest, are the sulfides of nickel and copper, since the economic recovery of both of these useful metals, from their ores, involves the formation of a sulfide at some stage of the operations.

Effect Of Manganese And Arsenic Upon Current Efficiency In The Deposition Of Zinc From Zinc Sulphate Solution, Justin Kelly

Bachelors Theses and Reports, 1928 - 1970

Throughout the entire experiment the electrolysis were conducted in an eight-hundred cubic centimeter beaker. An excellent circulation of the solution was assured by means of an electric stirrer, vigorous gas evolution from the anodes, and by means of a regulated feed-discharge system. By means of this balance, solution of the same impurity concentration as that of the electrolyte was fed in the cell just as fast as the discharge was syphoned out.
