The Design Of A Sampling Mill To Treat A South East Missouri Lead Ore, Robert Nathaniel Copeland, Edwin Cook Mcfadden Jan 1911

The Design Of A Sampling Mill To Treat A South East Missouri Lead Ore, Robert Nathaniel Copeland, Edwin Cook Mcfadden

Bachelors Theses

"The purpose of the work that was undertaken in preparing this thesis was to provide plans and specifications for a sampling mill to be erected by the St. Louis Smelting and Refining Co. at their plant near St. Francois, Mo... It was intended at the outset to design the plant completely and to provide full working drawings and specifications for all parts of the mill. On account of the lack of time, however, it has been found necessary to somewhat reduce the amount of work. As a result only general plans and specifications with a few of the more important …

Ratio Of The Thermal And Electrical Conductivities For Gas Carbon, Oscar Alan Randolph Jan 1911

Ratio Of The Thermal And Electrical Conductivities For Gas Carbon, Oscar Alan Randolph

Bachelors Theses

"The method of F. Kohlrausch for the determination of the ratio of the heat conductivity upside down gamma , to the electrical conductivity k of a substance is of practical value as well as of theoretical interest. Of practical value because there may be obtained from it - with much great ease than by direct methods - the heat conductivity which has immediate applications, not only to the design and construction of furnaces, but to various other matters of such import; of theoretical interest to the physicist, because of the Wiedmann-Franz and its consequent relation to the electron theory; to …

The Determination Of The Electrical Resistance Of The Human Body Under Conditions To Be Met Within Underground Mining, Duncan S. Smith, Paul E. Coaske Jan 1911

The Determination Of The Electrical Resistance Of The Human Body Under Conditions To Be Met Within Underground Mining, Duncan S. Smith, Paul E. Coaske

Bachelors Theses

"The use of electric wires in mines for power purposes is dangerous to human life. Deaths occur every year from electric shocks, and in most cases these accidents could have been prevented if some precaution had been taken by the victims, or if some care had been taken to protect them from coming in contact with live wires. Most workingmen accustomed to working around electric wires become careless and a lack of knowledge of the danger involved gives rise to the many accidents that occur each year...The object of this investigation is to determine just what resistance the human body …

Underground Records, Robert Hardy Bedford Jan 1911

Underground Records, Robert Hardy Bedford

Professional Degree Theses

"It may save confusion to now state that "Underground Records" is used in sense of information regarding labor, supplies, and output of the underground proper, in distinction from "Costs" - a term here used for results of the sum total of all records after they have passed through the hands of the book keeping-accounting staff. The essentials of underground records are more or less carefully collected by all mining companies of any importance, but are too often, before they have come under the eyes of the mine management in intelligible or suggestive form, obscured by the addition of a "witches …

Method Of Obtaining And Preserving Data On Churn Drill Holes, Ira Lee Wright Jan 1911

Method Of Obtaining And Preserving Data On Churn Drill Holes, Ira Lee Wright

Professional Degree Theses

"In prospecting for copper by means of churn drills it is absolutely essential that accurate methods of sampling be employed if any dependence is to be put upon the results. Of equal importance is the recording and preservation of data regarding each hole after results are obtained. This applies to such information as location and elevation of holes, depth, water level, geology etc as well as to the assays of the samples. Future underground development will be guided by information obtained from the drill holes and any incompleteness in the records will cause uncertainty in the development of the mine. …

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, …

Scheme For The Treatment Of Copper Smelter Flue Dust, John Perry Walker Jan 1911

Scheme For The Treatment Of Copper Smelter Flue Dust, John Perry Walker

Bachelors Theses

"In recent years, methods for improving the prevailing practice in treatment of flue dust have demanded the attention of those engaged in the copper and lead industries. Great advancement has been made in the more complete settling of the dust in large chambers and flues, and in some instances, more particularly in the case of lead smelters, in its extraction from the flue discharge of the furnaces by filtration through bags. Schemes for re-treating this recovered dust are, however, in a somewhat undeveloped state"--page 1.

Evidence Pertaining To The Origin And Deposition Of Ore Deposits, James Edward Mcgoughran Jan 1911

Evidence Pertaining To The Origin And Deposition Of Ore Deposits, James Edward Mcgoughran

Bachelors Theses

"In looking over the evidence grouped in the foregoing tables it is at once evident that by far the greater number of the ore deposits are associated with igneous rocks, and that they have resulted from deposition from not solution. It appears that, relatively, deposition by segregation from an igneous magma is of much less importance than deposition from solution, in the formation of ore bodies. However, segregation is the only explanation possible in accounting for some very important deposits, but they are very few in number. In distinguishing between deposits resulting from hot ascending meteoric solutions and those resulting …

A Comparative Test Of The Air Consumption Of Rock Drills, John Elmer Schultz, Christian R. Miller

Bachelors Theses

"The aim of this thesis is an attempt to determine the relative efficiency, of four standard types of rock drills, as to air consumption. The air consumption was based upon the cubic inch of rock drilled by each machine. The orifice method of measurement being utilized, in connection with the exhaust to determine the desired consumption"--page 1.

A Comparison Of The Silver Losses Due To Cupellation Using Different Kinds Of Cupels, James A. Taggart, Anton Frederick Karte Jan 1911

A Comparison Of The Silver Losses Due To Cupellation Using Different Kinds Of Cupels, James A. Taggart, Anton Frederick Karte

Bachelors Theses

"In this thesis our object has been to ascertain the silver losses in cupellation with different kinds of cupel materials, thereby determining the efficiency of the various materials used for making cupels. When beginning this work we hardly expected to find such differences in behavior of the various cupels used. However we refer the reader to our curves to see what really happened"--page 2.

Mine Map And Geology Of Saltpeter Cave, Milan Harrison Detweiler, Frank Edgar Townsend Jan 1911

Mine Map And Geology Of Saltpeter Cave, Milan Harrison Detweiler, Frank Edgar Townsend

Bachelors Theses

"The date of discovery of Saltpeter Cave is not known and there is no way of determining it. Numerous accounts are given of the cave by the oldest settlers in the neighborhood, some of which are both startling and interesting. for instance, it is reported that the soldiers of the Confederate army visited this cave for the purpose of securing guano from which to extract saltpeter for use in the manufacture of gunpowder. This may be the origin of its name"--Geology, Page 1.

Energy Loss In Commercial Condensers, Walter Roland Allen May 1910

Energy Loss In Commercial Condensers, Walter Roland Allen

Electrical and Computer Engineering ETDs

The investigation of the energy loss in condensers is one which electricians and experimenters have long carried on. Their efforts have been restricted chiefly to alternating currents. Many methods have been proposed and used with varying success. The losses in condensers are due to dielectric hysteresis and leakage. That the dielectric of a condenser becomes heated when an alternating current is applied to terminals has long been known. A condenser which has been charged does not lose its entire charge when it is discharged, part of it remaining as a residual charge. Kleiner used the thermo-couple embedded in the dielectric …

Our Rivals : The Molds, Yeasts And Bacteria., H. B. Knighton

Electronic Theses and Dissertations

In this day when the erstwhile plebian hog has taken to scaling the social ladder and has climbed beyond the ken of many an honest workman, it behooves the housewife to wage, with double zeal the warfare on our rivals, the molds, yeasts and bacteria who come as unbidden guests eating the very food that we must have, raising enormous families at our expense, frequently making themselves obnoxious as long as the food lasts, then quietly withdrawing into themselves and either waiting for a fresh supply of food or allowing the housewife to start them by the dust-brush route to …

A Swedish Population Of Worcester: A Study In Social Survey, Karl J. Karlson Jan 1910

A Swedish Population Of Worcester: A Study In Social Survey, Karl J. Karlson

Historical Dissertations & Theses

This paper is not going to be an historical sketch of the growth and development of the population, but instead a description of the status quo of an industrial, peace-loving, and law-abiding Swedish settlement. The material for this thesis has been gathered from statistics of churches and societies, in personal interviews with prominent men who has been closely associated with the Swedish people for a great many years, and from personal observation and investigation. It is needless to say, I think, that I shall present the facts as I have found them and be as impartial as anybody possibly can.
