The Disintegration Of Refractory Brick By Carbon Monoxide, Wilbur J. Darby Jan 1923

The Disintegration Of Refractory Brick By Carbon Monoxide, Wilbur J. Darby

Masters Theses

"In experimental work carried on at East St. Louis, Illinois in 1916 and 1917, with a furnace of commercial size for the electrothermic dry distillation of zinc ores, a difficulty that developed was the destruction of the firebrick lining in certain parts of the large condenser. The condenser was satisfactory in other ways, yielding a large proportion of the zinc as liquid metal, with no blue powder; but in order to obtain a proper length of service from the condenser it became necessary to find and overcome the cause of the disintegration of the lining ... it will be evident …

On The Breakage Of Rock Drill Steel, Muir Luken Frey Jan 1923

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 Jan 1923

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.


Design Of High Tension Outdoor Substation, Joseph Worley Jan 1923

Design Of High Tension Outdoor Substation, Joseph Worley

Bachelors Theses

"The present day tendency appears to be toward the more frequent use of outdoor substations, where not only the section disconnecting switches, but also transformers, lightning arresters, and indeed all high tension equipment, are exposed to the weather. The control of local feeder circuits at the lower pressures would be by means of switch-panels in cheaply constructed houses erected near the transformers"--Introduction, page 3.


Design Of A 100 Ton Asbestos Concentrator, Walter Gammeter Jan 1923

Design Of A 100 Ton Asbestos Concentrator, Walter Gammeter

Professional Degree Theses

"There are at present at least two methods in use for concentrating and classifying asbestos fibers, each of which is satisfactory when used to handle ores for which it was designed. The processes can be referred to, conveniently, as the pneumatic and gravimetric processes, deriving their names from the chief factors used in their schemes of operation"--Types of Asbestos Mills, page 3.


Organization And Development Of A Missouri Coal Mining Corporation, Riley Marsh Simrall Jan 1923

Organization And Development Of A Missouri Coal Mining Corporation, Riley Marsh Simrall

Professional Degree Theses

"Approximately 2350 acres of land in and around the town of Mosby, Clay County, Missouri, are held under Coal Mining Leases by the Mosby Coal Company, a Missouri Corporation. These leases were grouped to form a block under which mining operations might proceed in all directions from one principal working shaft. It is intended to set forth in the following report the factors which influenced the original incorporators of the Mosby Coal Company in leasing and prospecting this land for coal, and to describe, in a general way, the incorporation, financing, development and valuation of the property"--Introduction, page 4.


The Construction, Equipment And Operation Of The Second Largest Oil Refinery In Mexico, Arturo C. Fernandez Jan 1923

The Construction, Equipment And Operation Of The Second Largest Oil Refinery In Mexico, Arturo C. Fernandez

Professional Degree Theses

"In the preparation of this thesis the writer has endeavored to describe in a clear, concise and simple manner the general scheme carried out by the Foundation Company in the construction, equipment and operation of the Corona Refinery at Chijol, Veracruz, Mexico.

Under construction, the most interesting features of the work executed by the Field Engineering department have been discussed at some length. Throughout this paper elementary details have been omitted, the casual reader being assumed to possess a knowledge of the fundamental principles of engineering.

No attempt has been made to cover the activities of the allied--mechanical, electrical, architectural--departments …
