The Composition And Analysis Of Zinc-Lead Pigment, Evans Walker Buskett Jan 1907

The Composition And Analysis Of Zinc-Lead Pigment, Evans Walker Buskett

Professional Degree Theses

"Zinc is present as oxide and sulphate. There are also probably zinc and lead sulphites. It has been suggested that there may be carbonates in this pigment, but this is not probable as the high temperature of the furnace, the complete combustion of the fuel to CO2 and the large excess of SO2 gas in the bagroom would tend to prevent their formation. There is also a chemical combination between the zinc oxide and the lead oxide which is probably a zinc plumbate. Some light can be thrown on the subject by the following experiments:"--page 1.

Graphical Representation Of Compressed Air Formulae, John Thomas Vitt, Paul Andrew Philippi Jan 1907

Graphical Representation Of Compressed Air Formulae, John Thomas Vitt, Paul Andrew Philippi

Bachelors Theses

"Air during compression and expansion obeys the same laws as do other gases and these laws have been mathematically stated by purely rational formulae. Most of these formulae are logarithmic and their use involves a considerable amount of work. The object of this thesis is to present these formulae in such form that problems involving their use may be readily and easily solved. It was decided to present them graphically and the accompanying curves are the results of our labors"--page 1.

Efficiency Of Mill Practice In The Joplin District, Ira Lee Wright Jan 1907

Efficiency Of Mill Practice In The Joplin District, Ira Lee Wright

Bachelors Theses

"Milling in the Joplin District is, compared with the practice in other zinc fields, seemingly very crude. To one unacquainted with the peculiar conditions of this district, the amount of ore which goes into the tailing pile seems unnecessarily high. There are several things which account for the low saving made"--page 1.

Meridian-Projecting Instruments And Methods, Albert Babbitt Bartlett Jan 1907

Meridian-Projecting Instruments And Methods, Albert Babbitt Bartlett

Bachelors Theses

"The writer's attention was called to the necessity of knowing the accuracy attainable in surveying which must depend upon the Meridian, and therefore be subject to the accuracy of it, in seeking information by which to decide what would be the most desirable transit to use in the West, particularly for United States Deputy Mineral Surveying. Descriptions of the manipulation, adjustments, and the cost, etc., of the various appliances are plentiful in the text-books on surveying and in the various catalogues; but there was no very definite information in regard to the actual probable and average accuracy, especially in the …

The city is growing steadily and will in a few years be of such size that a sewage system will be necessary. We therefore submit the following plans, specifications and estimates. Since the city could not afford both Stone Sewers …

Plans And Estimates For The Disposal Of Sewage And Storm Water For The City Of Rolla, Mo., Tracy Irwin Phelps, Robert Arthur Barton Jan 1906

Plans And Estimates For The Disposal Of Sewage And Storm Water For The City Of Rolla, Mo., Tracy Irwin Phelps, Robert Arthur Barton

Bachelors Theses

"The City of Rolla is the county seat of Phelps County, situated 111 miles southwest of St. Louis, on the St. Louis and San Francisco R.R. This thriving city of 2000 inhabitants already owns the electric lighting system, and has engineers working upon plans for a deep well water supply system. Since the sanitary conditions are not the best and a water supply is to be installed, we submit these plans and estimates for a "Disposal of Sewage and Storm Water."--page iii.

Copper Matting Blast Furnace Run, John Vivian Stevens, Frank Bowman Powell, John Dozier Shanks Jan 1906

Copper Matting Blast Furnace Run, John Vivian Stevens, Frank Bowman Powell, John Dozier Shanks

Bachelors Theses

"The theory of the copper blast furnace run having been given us in the class room, we wishing to familiarize ourselves with the practical processes and the difficulties involved, selected it as the basis of an investigation of which the following is a correct report. The original ore was a high grade copper sulphide from the Ducktown, Tenn. district to which was added some heavy pyritic ore from various quarters. The latter was added to furnish the iron oxide necessary as a flux in the blast furnace and sulphur in sufficient amount to make the ore self roasting when charged …

A Special Investigation In Concrete Steel And Application To Square Set System, Horace Alonzo Hand Jan 1906

A Special Investigation In Concrete Steel And Application To Square Set System, Horace Alonzo Hand

Bachelors Theses

"This investigation has been prompted, first, by a desire to become more familiar with concrete-steel in its general application to engineering construction, second, by the inevitable necessity of a substitute in the near future for lumber in mining construction. In first case, a thorough review has been made of principles and practice in the construction of concrete-steel structures in general, including bridges, water towers, reservoirs, viaducts, etc., as found in current engineering journals, which is the most up-to-date source of information available. Special attention has been given to best practice in reinforcing concrete to resist forces of bending, shearing, torsion …

Treatment Of Joplin Tailings, Preston King Horner Jan 1906

Treatment Of Joplin Tailings, Preston King Horner

Bachelors Theses

"In the Joplin region are enormous piles of tailings, that for waste material, run very high in blende. This is due mainly to the temporary character of the mills which are built with more regard to low first cost than to receiving a high percentage of extraction. As a result we have some piles of tailings containing from 200,000 to 300,000 tons of materials that will average from about 2 to 3% zinc, and all crushed so as to pass through about #2 mesh"--Page 1.
