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 …

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 …

A Study Of The Pollution Of The Meramec River, William Quentin Kehr

Professional Degree Theses

"Early in 1940 a project was undertaken for a complete survey of the Meramec River Basin. This project, of which the pollution study was a part, was one of the most extensive surveys made of an entire river basin and included detailed studies of soil erosion, land, use, pollution, rainfall, and recreation in the Meramec Basin. The pollution study covered that portion of the Meramec River from its confluence with the Mississippi River to Steelville, a distance of about 140 river miles; the Big River from its mouth to a point west of Flat River, a distance of 107 river …

Missouri Super Duty Refractories And Their Probable Application For Blast Furnace Linings, Charles Alfred Freeman

Professional Degree Theses

"The use of Missouri Super Duty Refractories in steel plant service is not new, although their use in blast furnace service has been limited chiefly to stove installations. They have, however, been used in a sufficient number of places where severe operating conditions exist, so that they are a definitely known quantity and they have consistently shown much longer service under conditions of high temperatures and contact with slag and molten iron. One outstanding comparison of the service which these brick give over ordinary first quality brick is the bottom of a malleable iron furnace. Not first quality refractory has …

A Study Of Methods For The Purification And The Removal Of Color From Trinitrotoluene Wash Waters, William Wilson

Masters Theses

"Symmetrical Trinitrotoluene is stable in the presence of moisture, but the nonsymmetrical trinitrotoluenes permit replacement of a nitro group with the formation of a nitrated cresol and nitrous acid. Nitrated cresols form salts similar to the picrates. To avoid these nonsymmetrical trinitrotoluenes the Ordinance Department, U. S. A., requires that Grade I trinitrotoluene have a solidification point of at least 80.2⁰C.². Numerous methods for purifying the crude trinitrotoluene and others for separating the nitrotoluenes have been suggested"--Introduction, page 1.

I. SCOPE OF THIS REPORT Tests were conducted on nine beams with unstiffened top flanges, viz., 14-2 1/4-1,2,3; 16-2 1/2-1,2,3; 16-3,1,2,3. Beam 14-2 1/4 - 2 was the first to be spot-welded in our shop. This beam warped badly in welding and, when tested, failed at a much lower load thant the other two beams of the same type, due to initial distortion. For this reason the results of this test were discarded and are not included in this report. Beams 18-2 1/2 according to our drawing were to be of 18 ga. metal. It turned out, however, that all …

Subsurface Pressure Regulation Of High Pressure Condensate Wells, John Oscar Farmer

Professional Degree Theses

"The discovery of deeper production and higher pressures has resulted in the need for control equipment for preserving and protecting these great reservoirs of energy; and, in the case of high pressure condensate wells, has resulted in the need for means for preventing freezing or hydrate solidification caused by throttling the production. Development of a successful removable subsurface regulator has enabled operators to reduce dangerously high surface flowing pressures to safe workable limits; and, by moving the point of principal pressure reduction from the surface to warmer subsurface levels, has resulted in complete elimination of freezing conditions in flow lines. …

Applicability Of Hydraulic Drives To Oil-Well Pumping, James Francis Mcdonald

Professional Degree Theses

"To date, to the author's knowledge, there has been no successful application of the hydraulic drive to oil-well pumping. It is understood, however, that there is, at the present time, an installation in the Oklahoma City oil field, near Oklahoma City, Oklahoma, wherein a manufacturer of hydraulic couplings and an oil-producing company have cooperated in experimental work with the fluid drive applied to a pumping well. No technical data or information regarding the success of the application have, as yet, been released and, consequently, this work is presented primarily for the purpose of creating interest in the application of "Fluid …

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

SCOPE OF THIS REPORT all the beams heretofore tested in this program were furnished with web stiffeners in order to aviod crushing of the web at the load points and at the supports. In practical application the use of such stiffeners at points of concentrated loads would not only be uneconomical but also would impair the versatility of the elements, since stiffeners would have to be spaced on each individual beam according to the particular location and loading. For this reason it seem essential to investigate the resistance of unreinforced webs to concentrated loading. The tests reported herein are to …

Research Investigation Of Organized Drainage Districts In Mississippi, Lee Dorsett Dumm

Professional Degree Theses

"In the early days farmers attempted to drain their land individually, but they soon found that water did not recognize property lines. One farmer would ditch his land only to find that the water from his neighbor's farm would wash over has land and fill up his ditches. Another would attempt to ditch his land, but would find that no outlet was available for his ditch unless he constructed it across the land of his neighbor. Because of such situations, groups of farmers cooperated in constructing drainage improvements. However, difficulty was encountered in reaching an agreement as to the division …

A High Alumina Concentrate From Low-Grade Burley Clay, Leonard Stearns

Masters Theses

"The principal source of raw material for the production of high-alumina refractories are the diaspore clays of Missouri. These highly refractory clays contain a large percentage of the mineral, diaspore, a monohydrate of alumina whose theoretical chemical formula is Al₂O₃ʺH₂O. The clays as mined contain from 85 to 65 per cent alumina...Diaspore clays as now found fill sandstone-lined "sink holes" or depressions in the parts of the district underlain by rocks of the Pennsylvanian Age. They are rough open-textured clays, grey or buff in color usually, containing the mineral diaspore in the form of shot-like particles or "oolites." There are …

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 …

Determination Of Alkalies In Portland Cement By The Dropping Mercury Electrode Method, William Joseph Smothers

Masters Theses

"In many industries whose product or products contain alkalies, the determination of the amount present is very essential from a control standpoint. This present investigation is concerned with a method for quantitative determination of sodium and potassium as accurately as by customary chemical methods and which will require less time in its operation. Portland cement is a product in which the amount of sodium and potassium present is of prime importance. This importance of the alkalies upon the behavior of concrete was first noticed in California where, after numerous tests, it was definitely shown that with certain aggregates there was …
