Insoluble Residues Of The Lower Mississippian Limestones Of The Madison Group, Fred G. Lines May 1942

Insoluble Residues Of The Lower Mississippian Limestones Of The Madison Group, Fred G. Lines

Bachelors Theses and Reports, 1928 - 1970

The correlation of non-fossiliferous drill samples is one of the difficult problems that is en­countered in sub-surface stratigraphy. In order to truly correlate a formation, it must have some dis tinctive features and have an areal persistence of these features. These requirements are probably met best by limestone.

Bachelors Theses and Reports, 1928 - 1970

The Red Lodge and Silver Star chromite deposits of Montana have stimulated much interest during periods of war. The Red Lodge deposit is 25 miles southwest of Red Lodge which is also the nearest railroad point. Several workings are scattered throughout the area, exposing lense-like ore bodies averaging 33% chrome oxide. Silver Star is a much smaller deposit 5 miles west of Silver Star, Montana, which is its nearest rail­road point. Lenses of chromite are exposed by pits and trench­es, which average approximately 36% chromic oxide.

An Analysis Of Pressure Gasoline And Pressure Kerosene Stoves, Arnold E. Baragar Mar 1942

An Analysis Of Pressure Gasoline And Pressure Kerosene Stoves, Arnold E. Baragar

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During the past few years inquiries have been received regarding the cost of operation, efficiency, and performance of pressure gasoline and pressure kerosene stoves. Because of the method of operation and the use of gasoline as fuel, safety from fire and carbon monoxide has been frequently questioned. Not only is it necessary to have technical information about this type of appliance in order to compare it with other types but it is further important to know whether one type of burner is superior to another; whether one type of oven construction will give better results than another and in general …

Subsurface Pressure Regulation Of High Pressure Condensate Wells, John Oscar Farmer Jan 1942

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 Jan 1942

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 Jan 1942

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 Jan 1942

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 Jan 1942

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 Jan 1942

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 Jan 1942

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 …
