On The Breakage Of Rock Drill Steel, Muir Luken Frey

Masters Theses

"Prior to 1920 there was little attention paid to the general problem of breakage of rock drill steel. Each locality had its problem and the matter was treated as a purely local one, independent upon conditions in that particular section. But in the above-mentioned year, there arose an interest of wider scope, from what causes it is impossible to determine accurately, and the matter is now the subject of a broad investigation in which the users of rock drill steel, the United States Bureau of Mines, and the United States Bureau of Standards are cooperating...There is, to date, no satisfactory …

Effect Of Time And Temperature On Distillation Of Zinc-Lead-Silver Complex Sulphide Concentrates, Ernest Sterling Wheeler

Masters Theses

"Accurate information is lacking as to the effect of temperature and time of distillation on the relative proportions of zinc, lead and silver volatilized from complex ores, and while it is evident that the possibility of the commercial treatment of these complex ores has engaged the attention of metallurgists for years, it is one that will still bear investigation even on a small scale"--Statement of Problem, page 5.

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.

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 …

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 …

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.
