The Cost Of Producing Electricity At The Hamilton, Missouri Light And Power Company, Bernerd William Adams Jan 1916

The Cost Of Producing Electricity At The Hamilton, Missouri Light And Power Company, Bernerd William Adams

Bachelors Theses

"For those seeking information on the cost of producing electricity in steam plants, an unlimited amount of data may be found in the technical journals and text books. This information, however, is obtained from a careful analysis of the daily and hourly records kept by the largest central stations, hence, production costs are available only where the yearly out-put is several million kilowatt-hours. the small isolated stations of from one hundred to two hundred kilowatt capacity have not as a rule, become progressive enough to keep a complete record of operating costs...The test hereinafter reported was conducted from August 3rd. …


Some Chemical Problems In Geology, Reginald Scott Dean Jan 1916

Some Chemical Problems In Geology, Reginald Scott Dean

Masters Theses

"This thesis is in the main a compilation of the views held at this institution in regard to the problems discussed as interpreted by the author. No claims for originality are made except in the manner of presentation as the material used has been obtained by conference and class room work with Professor V. H. Gottschalk and Professor G. H. Cox and also to some extent with H. A. Buehler, State Geologist. On the other hand the material is an expression of these ideas as assimilated by the author and hence may in certain cases differ radically from the views …


Land Drainage In Central Iowa, Ernst Lorenze Chamberlain Jan 1916

Land Drainage In Central Iowa, Ernst Lorenze Chamberlain

Professional Degree Theses

"The problems encountered in land drainage are comparatively simple when seen from an engineering point of view. Most problems do not require a fine scientific or mathematical analysis but are rather questions to be decided by good judgment or practical common sense. The most difficult problems encountered are financial, legal and political, therefore, in this paper considerable attention is paid to the Iowa drainage law, facts learned from practical drainage men and to the organization and operation of the different financing systems for drainage"--page 1.


The Effect Of Temperature Upon The Crystal Size And Physical Properties Of Iron And Steel, Earl Joesting Mcnely Jan 1916

The Effect Of Temperature Upon The Crystal Size And Physical Properties Of Iron And Steel, Earl Joesting Mcnely

Bachelors Theses

"This investigation was deemed of sufficient merit to require the work of two terms. It naturally is divided into two parts, i.e., the effect that temperature has upon the crystal size; and the effect that temperature has upon the physical properties of iron and steel"--page 3.

The Relation Of The Composition Of Petroleum To Its Origin And Occurrence, John Warder Shotwell Jan 1915

The Relation Of The Composition Of Petroleum To Its Origin And Occurrence, John Warder Shotwell

Bachelors Theses

"Petroleum Is a mixture of hydrocarbons. It is a liquid varying from colorless, through yellow and brown to black. It varies from 1.0 to 0.80 in specific gravity, which corresponds to 10° to 45° Beaume. It varies widely in physical properties, such as viscosity, ignition point, polarization of light, etc. Chemically it is composed essentially of carbon and hydrogen, but usually contains impurities such as sulphur and nitrogen. The carbon and hydrogen combine with each other to form certain series, or "chains"--Chemical and Physical Nature, page 1.

The Measurement Of Mineral Electrode Potentials, John Charavelle Ingram Jan 1913

The Measurement Of Mineral Electrode Potentials, John Charavelle Ingram

Bachelors Theses

"The present investigation was undertaken with a view to consider the variables which tend to cause inaccuracy in the above mentioned measurements and as preliminary to a further study of the subject by the Missouri Bureau of Geology and Mines. The subject is one which, judging from the work of others and from my own experience, will require much more experimentation before results are obtained which are sufficiently reliable for the use of the economic geologist"--Introduction, page 3-4.


Volhard's Volumetric Method For Manganese, John A. Murphy Jan 1913

Volhard's Volumetric Method For Manganese, John A. Murphy

Bachelors Theses

"The purpose of this article and the data contained is an attempt to show how the percentage of manganese varies with different mounts of zinc salt present. It was also intended to determine the ratio of manganese to oxygen and zinc in the brown percipitate sic obtained upon the titration of manganese sulphate against a permanganate solution in the presence of varying quantities of zinc, but through an oversight the data is insufficient for this purpose"--Introduction, page 2.


The Measurement Of Compressed Air And Its Consumption In Rock Drills, Homer Kent Sherry, William Porri Jan 1912

The Measurement Of Compressed Air And Its Consumption In Rock Drills, Homer Kent Sherry, William Porri

Bachelors Theses

"The object of this thesis is to investigate the measurement of compressed air and to determine its consumption in rock drills. Our intention at first was to run more exhaustive tests on the drills, but due to the large amount of work necessary in rigging up the apparatus and computing results, we found it necessary to curtail our work to representative types of the hammer and the piston machines. We regret being unable to give more complete data in regard to the drills, but hope to point out fields for future work since, with the increased facilities now at hand, …


Roasting Pyrite For Magnetism With Minimum Sulphur Volatilization, Dale Irwin Hayes, Clark Watson Wright Jan 1912

Roasting Pyrite For Magnetism With Minimum Sulphur Volatilization, Dale Irwin Hayes, Clark Watson Wright

Bachelors Theses

"In Wisconsin and other zinc mining districts the blende is frequently found associated with pyrite and marcasite. In the Wisconsin district, especially, the marcasite content of the mine-run ore is high being frequently equal to and in many cases greater than the sphalerite content. At time the marcasite and sphalerite together constitute as much as 25 or 30% of the min-run ore. The characteristic milling treatment of this ore is; first, hand-picking, and then over grizzlies, tromells, rougher and cleaner jigs. Owing to the fact that marcasite and sphalerite differ but slightly in specific gravity the jig concentrate obtained is …


Crystallization Of Magmas, Norman L. Ohnsorg Jan 1912

Crystallization Of Magmas, Norman L. Ohnsorg

Bachelors Theses

"The object of this paper is to arrive at a better explanation of the segregation of magmatic solutions on cooling. In which magmas will be discussed from a chemical and metallurgical lien of reasoning, in showing why such minerals as apatite, magnetite, etc., having a comparatively low melting point, crystallize cut before feldspar and quartz, which have a comparatively high fusion point"--page 1.


Checker Board Drainage Due To Eroded Dikes, Julian Adolph Hielscher Jan 1912

Checker Board Drainage Due To Eroded Dikes, Julian Adolph Hielscher

Bachelors Theses

"The conclusions here drawn are the results of observations made during the past ten summers spent in this region while camping, fishing, and hunting; at first, with the native game wardens and fire rangers; later on independently or in company with some of the many tourists who annually visit this delightful region. In this manner it has been possible to cross and re-cross this territory in almost every direction. The highways into this wilderness are the streams and lakes and the only method of travel is by canoe, though short excursions can be made over land by following the paths …


Fluorspar Mining In Kentucky, Walter Coffran Richards Jan 1911

Fluorspar Mining In Kentucky, Walter Coffran Richards

Professional Degree Theses

"The mining of fluorite, or fluorspar in Western Kentucky is one of the chief mineral industries of that State. As the number of mines and prospects is very great, a thorough treatise on the geology, mines, and methods of this district would make a large volume. This thesis will deal, however, with only a small part of the district, in which the mine operated by the author is located. Before going into detail, it might be well to mention a few points relative to the fluorspar industry in general. To the average person, fluorspar seems to be unknown. In fact, …


Modern Cyanide Practice, Harvey Edson Smith Jan 1910

Modern Cyanide Practice, Harvey Edson Smith

Bachelors Theses

"It is noticable sic that about all of the recent improvements in cyanide practise sic have been along mechanical rather than chemical lines. the use of oxidizers such as air, ozone, sodium peroxide, etc., the use of the salts of lead, and even the addition of a coating of lead to the zinc shavings in the extractor boxes were all recommended when the process was first advocated but sometimes for different reasons. In the early days of the process the addition of hypochlorites, alkaline persulphates, and the use of mercuric cyanide was also investigated but has not proven satisfactory owing …


Dredging, Swan River, Colorado, Henry William Lohman Jan 1910

Dredging, Swan River, Colorado, Henry William Lohman

Professional Degree Theses

"Operations for the extraction of gold from the gravels of this river, were started about ten years ago, at which time it was attempted by means of hydraulic elevators, later by means of the early type dredge, Risdon design, of which three were installed, and later still, an early type Bucyrus Dredge. These all resulted in failure, some alleged to have been due to impossibility of reaching bed-rock; small yardage capacity; and fraility [sic] of design. these have been overcome in the latest type of dredge constructed by the Bucyrus Company, description of which follow later. Dredging here, differs from …


A Comparison Of The Solvents Used In The Hydrometallurgy Of Silver, Simon Jochamowitz, Enrique Cavazos Jan 1909

A Comparison Of The Solvents Used In The Hydrometallurgy Of Silver, Simon Jochamowitz, Enrique Cavazos

Bachelors Theses

"Potassium cyanide solutions, hyposulphite of soda solutions, and a mixture called the Russell solution, are the solvents most used to win silver from its ores. We are not the first to attempt comparisons of the solvent powers of the different solutions named. It is difficult, at least we have found it difficult, to find tabulated, a comparison of the various solvents from the points of view of speed of action, of consumption of reagents, of suitability of one or another to a given type of ore"--page 1.
