Missouri School Of Mines, Civil Engineering Department Survey Data. Including The Adjustment Of The Triangulation Net On The M.S.M. Campus, Joe Beaty Butler, Roy Oscar Erickson, Wayne Shannon Frame

Professional Degree Theses

"In taking up the adjustment of survey data on the M.S.M. Campus the first thing to determine [is] the use for said data. The data is used by the Department to determine whether or not the student in his Field Work has pursued correct methods. No attempt is made to require great precision as the student is just learning to use the instruments and time is not allowed in the courses for him to learn other than the rudiments of Surveying"--Part 2, Adjustment Data, Narration of Adjustment Methods, page 24.

Oil Possibilities In Western Kansas And North Central Wyoming, Joseph Stewart Irwin

Professional Degree Theses

"The reported discover of oil in the McNab well in the northwest corner of Trego County, Kansas, has attracted attention to that region as possible oil producing territory. The offer of certain blocks of leases on several so-called "oil structures" occasioned the reconnaissance made by the writer. The prospects were examined during the period, September 28 to October 14, 1921"--page 1.

Applications Of Method Of Least Squares To The Adjustment Of Level Circuits: Adjustment Of Elevations In Dawson And St. James Townships, Phelps County, Missouri, Clarence Edward Bardsley

Professional Degree Theses

"An introduction to a thesis on least squares could be drawn out to considerable length in explanation: as the purpose of this thesis has been an investigation in applications of the method of least squares to the adjustment of level circuits, it will be found in the body of the report considerable space has been devoted to the explanation of the different applications of the method, with a view that these investigations may be of use to engineers in the profession; so the introductory remarks will be brief ... The method of least squares takes first rank as an arithmetical …

The Roasting And Magnetic Separation Of Wisconsin Ores And The Utilization Of The By-Products, Earl George Deutman

Professional Degree Theses

"In the Wisconsin field, the zinc blende is usually found associated with iron sulphide in the form of marcasite. This ore, after being milled and concentrated at the mines, is sent to separating plants for further treatment by roasting and magnetic separation, inasmuch as the mixed blende and marcasite concentrate, owing to the high iron content, is not suitable for the zinc smelter, and the magnetic separation scheme of separation must be resorted to"--page 1.

The Flood Control System Of Newport, Ark., Alvis Frederick Denison

Bachelors Theses

"Vast sums each year are expended on flood control projects on the Mississippi river and its tributaries. Millions of acres that were formerly subject to annual inundation caused by overflows, have been reclaimed for agricultural purposes, and each year, an increasing amount of this sort of work must be done as quicker run off and an increased volume caused by the clearing of land and drainage of natural storage, results in higher flood stages. Of course the greatest work of this kind has been done along the Mississippi river, where great levees on each side from Missouri to its mouth …

The Effect Of Sulphur Dioxide Gas On Sweet Potatoes, Cotton, And Sorghum Cane Plants, Milburn Leo Dorris

Bachelors Theses

"The chief allegation made by many of the complainants sic in the vicinity of the zinc smelters is that the emanations from the stacks are detrimental to the yield of the crops, especially Sweet Potatoes and Cotton. They claim that on account of the leaves being burned or bleached, the entire plant is poisoned and weakened and the yield is thereby reduced. It was even claimed by some that the presence of the smoke in the atmosphere around the plant has a weakening effect in that it is cumulative, and, while it does not always visibly show, yet the general …

A Metallographic Study Of Copper Mattes, Edward James Torrence

Bachelors Theses

"The metallographic knowledge of copper mattes or mattes in general for that matter, although extensive, is, to put it mildly, rather diversified. One authority, for instance, believes that mattes are sulphide dissolving compounds there being no eutectiferous series involved. Another believes that the matte constituents enter into a eutectiferous series, compounds being present. Still a third contends that there are no compounds formed but that a simple eutectiferous range exists between certain limits outside of which the end members of the series form solid solutions with each other. In so far as there exists seeming absolute proof for all of …

Design And Construction Of The Experimental Mine, Robert Knox Stroup

Masters Theses

"The mining laboratory and experimental mine at the Missouri School of Mines was opened in 1913. At a suitable location, on the site of an old dolomite quarry, one and one half miles southwest of town a tunnel was started into the hillside and the necessary plant erected. This plant consisted of a fifty horse-power Erie Iron Works boiler of the modified locomotive type, and an Ingersoll Rand type 10 single stage duplex air compressor of a capacity of one hundred cubic feet of free air per minute. This plant was in operation during the fall months of each year …

The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge

Masters Theses

"One of the most serious difficulties confronting anyone working on stratigraphic problems in the Ozark area is the lack of detailed faunal lists of the various formations. A great deal of general work has been done, but very few detailed faunal studies have ever been published, and correlation of the Missouri section with sections in adjoining states is often difficult.

In a recent paper, Dake has discussed the origin and correlation of the St. Peter sandstone. In this study he found considerable difficulty in correlating the various formations above the St. Peter, and at his suggestion, the present study was …

The Equilibrium Of The Reaction Zn + Co₂ = Zno + Co, Clarence Ware Burkhart

Masters Theses

"Many attempts have been made in the last twenty years to smelt zinc ores in the electric furnace. The disadvantages of the present retort process have been discussed so often that they need not be dwelt upon here. The principle ones are, the low thermal efficiency of the retort furnace, low metal recoveries, small smelting units necessary, short life of the retorts and the difficulty of treating impure and low grade ores. Electric smelting offers remedies for most of these difficulties"--Introduction, page 1.

Determination Of The Solubilities Of Lithium, Sodium, And Potassium Sulphates In Absolute Methyl And Ethyl Alcohols, Jennie Lynn Lenox

Masters Theses

"It was thought by the author that there might be some relation between the solubility of a salt in the alcohols and the position of those alcohols in the series of monohydric alcohols; that is, that there should be a definite increase or decrease in the solubility of any particular salt in going from a higher to a lower alcohol. The object of this paper was to find the solubilities of some simple salts in as pure alcohol as could be prepared, and to find any relationships if possible"--page 2.

The Action Of Tan Bark In The Manufacture Of White Lead By The Old Dutch Process, Elmer List

Masters Theses

"This investigation was undertaken because there is very little definite information in print, regarding the micro-organisms which play such an important part in the Old Dutch Process for manufacturing white lead. The statements concerning this process are very general in character. For instance, one book states, "The first action which goes on is to convert blue lead into basic acetate of lead. This is brought about by the heat of the fermenting tan, causing the evolution of acetic acid from the liquid of the pots." Albert H. Hooker in a little treatise on white lead says: "As it stands now, …

Investigations In Colloidal Phenol, Charles James Millar

Masters Theses

"In making some experiments with various colloids it was noticed that phenol and water seemingly formed a colloid, so it was deemed advisable to experiment farther and see if this fact could be established. The references on this subject vary widely and for this reason some of them are given here. Ostwald recognised [sic] the colloid state of a phenol-water mixture at the critical temperature but evidently failed to see the possibility of the phenol-water colloid at all temperatures. In the following article I will try to show that the phenol-water mixture forms a colloid, not only at the critical …

High Speed Steel - Its History, Development, Manfacture, Metallography, And Constitution, Including An Extended Bibliography, James Presley Gill

Masters Theses

"There is no doubt but that the making of Steel was known and practiced by the early Greeks probably several centuries before the birth of Christ. There have been discoveries of pre-historic forges and smelters evidently used for the making of iron and steel and it is certain that implements made of these materials dates back to antiquity. As to the methods of making the steels of antiquity there is little known, but it is quite probable since iron has a strong affinity for carbon that in the forging of the iron it's contact with the carbonaceous fuel would absorb …
