A Study Of Electrometric Methods For Determining Selenium And Tellurium, Bertie Lee Browning

Masters Theses

"The quantitative oxidation of tellurious acid to telluric acid by potassium dichromate has been shown by Lenher and Wakefield to be applicable to the volumetric determination of tellurium. The purpose of this investigation was to study the applicability of the electrometric method to this titration"--Introduction, page [1].

The Properties Of Refractories In Zinc Metallurgy. Part Iii. Comparison Of Various Clays, Richard Elkanah Sears

Masters Theses

"This thesis...contains a description of a part of a general investigation on the subject of the refractories used in the distillation of zinc. This investigation has been in progress for the past eighteen months at the Mississippi Valley Experiment Station of the United States Bureau of Mines, Department of Commerce, in cooperation with the School of Mines and Metallurgy of the University of Missouri. The first phase of this investigation had for its theme the determination of the properties of the fire clays and body mixtures now used in the manufacture of zinc retorts. The second phase deals with the …

The Properties Of The Fire Clays Used For The Manufacture Of Zinc Retorts, Adolph Harmon Kuechler

Masters Theses

"The ultimate object of this refractories investigation is to develop a body for zinc retorts, or changes in the method of their manufacture, that will result in better retorts than the ones now in use. In doing this, the question of permissible cost must, at all times, be kept in mind. The immediate object of the present phase of this investigation, of which this thesis covers only a part, is to determine the physical and chemical properties of the refractories (fire clays, grogs, bodies, etc.) now used for the manufacture of zinc retorts. This will be a basis for later …

Transmission Of Electrical Energy At 220,000 Volts, Robert Wilhelm Ahlquist

Bachelors Theses

"A. E. Silver at the Annual Convention of the A.I.E.E. in 1919 gives some of the reasons why 220,000 Volt transmission is a logical and feasible commercial proposition. He also gives some of the main features of the undertaking...Owing to the great scope of this paper it has been thought necessary to generalize on the discussion of the first two topics and to treat the next two in more detail"--Statement of Scope of this Paper, pages 3-4.

Lactose Fermenting Bacteria In The Water Supplies Of The Rolla Quadrangle, Joe Beaty Butler

Masters Theses

"I. Preliminary investigations. This includes the securing of 139 water samples from water sources in the Rolla Quadrangle, and inoculating 1cc samples from these into Dunham's Lactose tubes and thereby getting lactose gas production checks on the field samples. II. Confirmatory tests. This consisted in the isolation of lactose fermenters on Eosin-Methylene Blue Agar and checking of the cultures back through the lactose and then through dulcitel and saccharose so as to complete Jackson's Classification. 106 cultures were classified in this manner. III. Running through a complete set of tests of pure cultures, so as to completely (as possible) identify …

The Solubilities Of Certain Inorganic Salts In Anhydrous Normal Alcohols, William Orval Keeling

Masters Theses

"An examination of the literature shows that extensive studies have been made of the solubilities of inorganic salts in aqueous, normal alcohols, but that little has been done in determining the solubilities in anhydrous alcohols. Northing was found of a systematic study of the solubilities of NaCl, KCl, NaN0₃ and KNO₃ in the lower alcohols over a fairly wide range of temperature. The author has made a study of the solubilities of the above mentioned salts in lower anhydrous normal alcohols at the temperatures 20°C, 25°C, 30°C and 40°C"--Introduction, page 1.

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.

Boiler Feed Water Purification At The Gorge Power Plant, Akron, Ohio, Bernerd William Adams

Professional Degree Theses

"The conditions of operation at the Gorge Power Plant were such that raw water was used in all the boilers. The boilers were operated at an average of about one-hundred and seventy-five percent rating and considerable scale formed in the tubes of the boilers. It was evident that this caused a large loss in fuel and increased the expense of maintenance. It was necessary to employ a number of men to remove the scale. An investigation was made to determine as nearly as possible the loss caused by the use of impure water. After the investigation, an attempt was made …

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 …

Glucose From Corn Cobs, Barney Nudelman

Masters Theses

"The efforts of American chemists in recent years have been devoted largely to the utilization of our waste products...Corn cobs offer a particularly inviting field for research along this line on account of the large supply of cobs available and the variety of substances obtainable from them. One of the leaders in this branch of investigation is Dr. F. B. LaForge of the Chemistry Division of the Bureau of Agriculture, who has contributed numerous papers on the subject. In one of these, in collaboration with C. S. Hudson, he describes, among other things, the preparation of glucose, but recognizes the …

The Copper Deposits Of Shannon County, Missouri, John Hyer Bowles, Lewis Ely Davidson

Masters Theses

"The object of this report has been three-fold. First, it has been deemed necessary to discuss the general geology of the area about Eminence, showing the distribution and character of the different formations. The distribution is shown on a topographic map of the Eminence Quadrangle...In the second place, it is intended to give a detailed account of the history, development, and extent of mining operations in Shannon county, with the amounts of production and the occurrence of the ore. The third object of this report is to develop a probable theory for the genesis of the ore, and to discuss …

Furfural (Furfuraldehyde) And Some Of Its Derivatives, Marion Smith Badollet

Masters Theses

"In the spring of 1919 the Eastman Kodak laboratories suggested to the chemistry department of the Missouri School of Mines and Metallurgy that experiments on small-scale production of furfural be undertaken. After a series of experiments a small amount of this product was made and a report was given before the American chemical Society at St. Louis in April 1920. The furfural prepared at the Missouri School of Mines and Metallurgy was sold to the Eastman Kodak laboratories. Within recent years very little experimental work has been done on furfural. It commands a high price as only small amounts are …

Characteristics Of Bacillus Influenzae, Georgena Josephine Clarke

Masters Theses

"This organism is classed under the type of haemoglobinophilic bacteria, due to the fact that its growth is restricted to a special medium containing haemoglibin [sic]. It is a very small bacillus which in the sputum tends to show itself in aggregations, especially centering about other organisms, M. tetragenus in particular"--page 3.

The Mexican Oil Fields, Raul Chavez

Professional Degree Theses

"Owing to the large area involved in this paper it is proposed to give only briefly the history, geology and development of the oil industry in Mexico, as well as to discuss in a general way the present oil legislation which has brought so much comment in the papers and has raised to much diplomatic trouble between the Mexican and United States Governments. This discussion is therefore of a brief nature and only the most culminant features and details of the subject in mind are here treated. The information and data here given were accumulated during personal examination of the …
