A Technique For Making Torsion Balance Surveys Of Inundated Areas, Karl Frederick Hasselmann

Professional Degree Theses

"The need for a technique for making torsion balance surveys of inundated areas was brought to the writer's attention during the years of 1927 to 1933, while employed by The Sinclair Exploration Company to prospect for oil in Austria, Hungary and North and Northwest Germany. At that time, the company was using ten torsion balances, supplementing the work with magnetometer surveys and refraction seismograph detail. During part of this period an elementary and relatively insensitive gravimeter was used. Some reflection seismograph work was also done during the last year of operations. During the course of surveying in North and Northwest …

A Comparative Analysis Of Some Recent Mining Practices In The Tri- State Mining District, James Francis Alexander Taylor

Masters Theses

"The Tri-State District, encompassing contiguous corner portions of Southwest Missouri, Southeast Kansas, and Northeast Oklahoma, has been, for many years, the leading zinc producer of the United States. However, rising labor costs and decreasing grade of ore reserves have meant that many of the mines gradually have become marginal in the economic character of their operations. In an attempt to counteract these adverse effects, steps were taken to attain lower cost mining methods, and mechanization has been introduced over a period of years. Further, the research program of the Eagle-Picher Company, the leading producer of the district, has been accelerated …

A Study Of The Separation Of Feldspar From Missouri Granite, Vernon Louis Kasten

Masters Theses

"The greatest use of feldspar is as a flux in the Ceramic Industry where it is used in the manufacture of abrasives, floor tile, terra cotta, china, and earthenware of all types. It is also used in the manufacture of glass and enamels, and much is used as grinding medium in powdered form because it is softer than the common abrasive, quartz...Missouri Granites are composed of feldspar, quartz, mica, and other materials, which may or may not occur in all the samples. It is the purpose of this investigation to attempt a separation of the feldspar from these other components …

The Solubility Of Zinc Ethyl Xanthate In Water, Thomas M. Mckenzie

Bachelors Theses and Reports, 1928 - 1970

A determination of the solubility of zinc ethyl xanthate was attempted by measuring the refractive index of a saturated solution of that salt. The small increment in refractive index effected by adding zinc ethyl xanthate to water in saturation quantities rendered measurements difficult and of dubious accuracy.

The Development Of Ethyl Cellulose Lacquers For Automotive Use : An Ethyl Cellulose Lacquer For Coating Plastics., Robert Carlton Krueger

Electronic Theses and Dissertations

There have been developed various colored ethyl cellulose lacquers that compare favorably with standard nitrocellulose lacquers in physical tests. Ultra violet light caused rather pronounced darkening of the lighter colors such as white and light yellow, probably because of the use of high amounts of phenolic resin. Also because of the presence of relatively large amounts of phenolic resin, the cost was somewhat higher than a comparable nitrocellulose lacquer. Suggestions for further work and improvement are included. An ethyl cellulose lacquer has also been developed to be applied by spray or brush to ethyl cellulose plastics with a minimum amount …

Some Applications Of Statistical Quality Control Methods To The Preparation, Purchase And Calorimetry Of Steam Coal, Arthur P. Bellinghausen

Bachelors’ Theses

This thesis is an attempt to establish the applicability of a statistical method of quality control to several problems involving maintenance of fuel quality standards. Although the technique has found increasingly important applications in mass production industries, its use in analysis of fuel characteristics has been given little, if any, study if current catalogues of the literature are authoritative. Analyses of data drawn from publications of the Bureau of Vines have been used to test the limitations of the method. Original data collected by the author shows statistical control to exist over sufficient samples to assure the soundness of conclusions …

The Use Of Carbon Dioxide For Dislodging Coal In Mines, Durward Rice Schooler

Professional Degree Theses

"The coal mining industry prior to 1940, was undoubtedly facing a period when operating economies and efficient utilization of labor, machines and modern practices were more necessary than ever before. With its markets definitely threatened by other sources of heat and power produced with a minimum of labor, "Coal" had to exert every effort to secure the lowest possible production cost and also to produce a more satisfactory product with greater safety to men and mines...Many attempts have been, with various methods, to invent a method of breaking down coal that would fulfill the requirements stated above. In 1924 or …

The Combustion Of Phosphorus, Erwin Charles Hoeman

Professional Degree Theses

"Phosphorus first joined the ranks of large-tonnage industrial raw materials about ten years ago, with the development of the electric furnace method for its production from rock phosphate. For many years before the present era of large-scale production, phosphorus had been little more than a laboratory curiosity. Thereafter, it found extensive application in pyrotechnics, match tips, rat poisons, and other uses not requiring more than a few hundred of tons in a year. Phosphoric acids were generally produced by the reaction of sulfuric acid with rock phosphate. The development and growth of electro-thermal processes for the reduction of rock phosphate …

Drainage As A Factor In The Development And Operation Of A Mine, Peter Paul Ribotto

Professional Degree Theses

"Peele's "Mining Engineers' Handbook" lists six of the more vital factors influencing the method of development and operation of a mine. These are (1) topography, (2) local geology, (3) location and mining of oreshoots, (4) haulage problems, (5) drainage, and (6) ventilation and safety. The purpose of this thesis is to provide a scheme for studying the drainage factor and to show how much a scheme works out in actual practice. Even the casual observer will note the interdependence and interrelationship among the factors listed. So closely tied together are they that the reasonable discussion of an item such as …

Floods Of May 1943 In Missouri, John August Short

Professional Degree Theses

"The year 1943 will be remembered for a long time as a year of great floods in the Middle West. Floods were occurring in some section of Missouri from April to June. The period of highest stream flow in general occurred during the month of May, and it is the May flood to which this paper pertains. It is quite possible that the importance of this flood is not generally recognized. Although everyone realizes that it was a major catastrophe, only planners for the future, particularly designing engineers, can fully appreciate the benefits which will be obtained from the information …

Electroplating Of Chromium Upon A Nickel Plated Magnesium Alloy, Harmel Dawson

A Study Of The Flow Properties Of Concentrated Clay-Water Mixtures, William Joseph Smothers

Doctoral Dissertations

"The study of flow properties of many substances is of prime importance in varied industries. The ceramic industry is mainly concerned with these measurements on a relatively stiff ceramic body, i.e., one which contains only enough water to retain its shape after the deforming force is relieved.

Various types of instruments have been devised to measure flow properties in the so-called "true plastic range." Since the primary measurements were made on instruments of the transpiration type to devise the laws of viscous and plastic flow, it was felt that an instrument employing the flow of the plastic material through an …
