A Comparative Study Of Some Rock Drill Bits, Paul Louis Terrasson

Masters Theses

"This paper describes a comparative study which was made of the wear and efficiency of different types of rock-drill bits when used under various drilling conditions...The four types of experiments which were carried out had the following purposes: 1. Determine the influence of the size of the bit. 2. Determine the influence of the design of the bit. 3. Determine the influence of the type of hammer. 4. Compare the performances of steel and tungsten carbide bits in limestone and in granite"--Introduction, page 1.

The Effect Of Spontaneous Crystallization Of Some Inorganic Compounds At The Critical Temperature Of Their Solvents, John William Buttrey

Masters Theses

"For many years the phenomena which occur at the critical temperature of liquids have been investigated. And since 1912, when Laue and other discovered that a beam of x-rays could be made to yield a diffraction pattern by passing it through a crystal, scientists have been attempting to change the x-ray pattern for various crystals by somehow changing the arrangement of the atoms in the crystal lattice. Harvalik has already shown that crystallization occurs when a solvent reaches the critical point and his work indicates that under these conditions of crystallization there is a change in the crystal pattern. The …

Hysteresis Loss Of Supermalloy At Different Temperatures, Chester Ray Holland

Masters Theses

"The object of this investigation was to measure the hysteresis loss of supermalloy at different temperatures, and to see if temperature had any effect on hysteresis loss and permeability. The maximum magnetizing current was held constant for all temperatures"--Introduction, page 1.

Ceramic Possibilities Of Some Missouri Clays And Shales, Leonard Nathanael Larson

Masters Theses

"Although many of the shales and clays of Missouri have in the past been, or are presently being used for the manufacture of heavy clay products such as face brick, common brick, sewer pipe, and tile, there is in these post-war years a significant shortage of these products within the state and country. Especially in the northwestern part of Missouri is there a distinct shortage, as only one structural clay plant is known to be operating in that area. The St. Louis and Southeastern Missouri districts are better prepared to meet construction demands, with several structural clay plants operating at …

The Solubility Of Copper In High-Iron And Low-Iron Slags, Charles Burroughs Gill

Masters Theses

"A thesis giving the details of construction of a rotating induction furnace and its use to experimentally determine the amounts of copper absorbed in high-iron and low-iron slags at various temperatures. A rotating induction furnace is advantageous for slag study in that the slag is contained in a molten pure metal cup and does not come in contact with any refractory, which would be attacked by the slag and contaminate it. The molten pure metal cup is formed by melting the pure metal in a refractory crucible and spinning this inside an induction coil. The induction coil supplies heat for …

The Use Of Wetting Agents In Clay Bodies, Nathan Russell Sewell

Masters Theses

"It has been observed that one of the weak points in the present method of commercially preparing stiff mud bodies is the de-airing process, which involves passing them thru a vacuum chamber. Difficulties in maintaining a good vacuum, power costs, and work stoppages due to clogged vacuum chambers, are some of the problems. It was thought that perhaps a very definite contribution could be made in the field of ceramic engineering if some method could be devised for preparing a workable ceramic body of good dry and fired properties without the use of a vacuum chamber. In attacking the problem, …

An Analysis Of Man Power Efficiency In Drilling Procedures In The Tri-State Mining District, Julian Alban Fuller

Masters Theses

"This thesis embodies the results of an investigation, by the time study method, of certain phases of drilling procedures recently brought into practice in the Tri-State mining district. The field work was accomplished during the months of July, and August 1945; the data obtained therefrom and the analysis presented in this dissertation apply to the practice in effect at that time"--Preface, page ii.

A Study Of Mine Scraper Buckets And Their Efficiency, Austin Bond Clayton

Masters Theses

"The use of power drawn scrapers, often called "slushing", for the moving of ore, stops filling, and waste rock has become standard practice in many mining operations. Several types of scrapers have been developed by practical application or by trial and error methods. However, a direct comparison of these scraper types under identical conditions has not been noted in a review of literature on the subject of mechanical loading. Written inquiries to authorities on scraping practice have brought replies that no previous comparisons of scraper types on a modal scale have been attempted. Therefore, the following thesis problem was set …

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 …

Geological Reconnaissance Of The Coldwater River, Mississippi, Pinckney Ronald Mabrey

Professional Degree Theses

"This report was the result of an assigment [sic] to make a geologic reconnaissance of the headwaters of Coldwater River in northwest Mississippi, on which a site for a flood control dam had been made. At the time of the last field work in November, 1940, the boring program for borrow areas and for foundation had been completed.

The Sardis dam on the Little Tallahatchie River, some 35 miles southeast of site for the Arkabutla dam had been recently completed, it being the first of several designed for flood control purposes in the Yazoo basin, Mississippi. This was a hydraulic …

Recovery Of Manganese From Oxidized Ores As Iron-And Phosphorus-Free Soluble Salts, Emil Pietz

Masters Theses

"There is a great demand at present for this country to develop its manganese resources. The hazards encountered because of the present international crisis make it almost impossible to import high-grade ores. Manganese is one of the most important strategic metals because it is vital to the production of steel. After the stock piles are depleted and the imports decreased, the deficit must be supplied by the domestic deposits. A great deal of research has been done to concentrate the domestic low-grade ores but new problems have always been encountered. The differences in the properties of the low-grade ores from …
