The Sedimentary Petrography Of The Oil And Gas Producing Horizons In Montana, Patrick J. Donahue May 1952

The Sedimentary Petrography Of The Oil And Gas Producing Horizons In Montana, Patrick J. Donahue

Bachelors Theses and Reports, 1928 - 1970

Montana is an excellent oil province, as oil and gas are pro­duced from a wider range of beds in the geologic section than in any other district in the United States. (1,864) Commercial fields have been developed in Ordovician, Devonian, Mississippian, Pennsylvanian, Jurassic, Lower Cretaceous, and Upper Cretaceous. It is believed that by describing the physical characteristics of the producing horizons, and by placing this information in one compact volume, a better under­standing of oil and gas occurrence in Montana may be gained.

The Effect Of Ferric Iron Upon The Current Efficiency And The Deposition Of Copper In The Electrowinning Of Copper From Copper Sulphate Solutions, James L. Owings May 1952

The Effect Of Ferric Iron Upon The Current Efficiency And The Deposition Of Copper In The Electrowinning Of Copper From Copper Sulphate Solutions, James L. Owings

Bachelors Theses and Reports, 1928 - 1970

In the hydrometallurgy of copper, probably the most widely used method for the precipitation of copper is by electrolysis using insoluble anodes. The process is similar in many respects to the electrolytic refining of copper; one of the main differences is the use of insoluble anodes in electrowinning as compared to the use of impure copper anodes in electrorefining. Impurities, however, are common to both processes. The nature of these impurities differ and the problem of purifying the electrolyte is also different.

Some Applications Of Geology To Civil Engineering With Special References To New Mexico And The Southwest, Eldred Ray Harrington May 1952

Some Applications Of Geology To Civil Engineering With Special References To New Mexico And The Southwest, Eldred Ray Harrington

Civil Engineering ETDs

Civil Engineers are usually specialists in some branch of the great field. They often get so deep into the forest that nearby trees effectively obscure the forest as a whole. The same is true of the specialists in the numerous branches of the field of geology. The writer has a certain advantage in this study. Not only has he had approximately equal training in both fields but he has lived almost thirty years as an observer outside the "forest", taking occasional excursions into the thickets of the fields but never staying so long in any one of them that he …


Development Of Electro-Mechanical Equipment For The Measurement Of Knock Characteristics Of Gasolines, Rudolph W. Ebacher May 1952

Development Of Electro-Mechanical Equipment For The Measurement Of Knock Characteristics Of Gasolines, Rudolph W. Ebacher

Mechanical Engineering ETDs

It was considered by the writer that characteristics of oscilloscope wave forms representing the varying pressures taking place in the CFR engine cylinder might provide an index to octane ratings of gasoline. Obtaining pressure wave forms on the oscilloscope required some medium for providing an electrical signal in response to engine cylinder pressures. A quartz pressure element was considered as the item that could fulfill this requirement.

The Discharge Coefficient In The Coordinate Method For Measuring Pipe Flow, Day L. Bassett May 1952

The Discharge Coefficient In The Coordinate Method For Measuring Pipe Flow, Day L. Bassett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agriculture, industry, and community life continue to impose great demands upon available sources of water, particularly in arid and semi-arid regions. Efficient utilization of water, demanding careful distribution and use, implies flow measurement.

The coordinate method for measuring pipe flow finds some application in industry where estimates must be made of the flow of fluids containing relatively large amounts of suspended solids that would render other measuring devices ineffective. Widest application may be found, however, in agriculture where a simple, quick, and inexpensive means for estimating well flow, pump discharge, drain efflux, etc., is necessary if the farmers are to …

Methods Of Routing Floods Through Reservoirs, Rowland W. Fife Feb 1952

Methods Of Routing Floods Through Reservoirs, Rowland W. Fife

Civil Engineering ETDs

Flood routing through reservoirs serves several major functions. It makes possible the determination of the effect of a reservoir, whether constructed for flood control purposes alone or for other purposes, on historic or predicated future floods at the reservoir site. The effect at the dam site then provides a basis for calculating the effect downstream. It also aids in obtaining the proper manipulation of gated spillways on multiple purpose reservoirs to provide the most advantageous flood control on the stream and at the same time make the best use of the water for power, irrigation, or other purposes.

Marcasite From The Upper Mississippi Valley Zinc Area As A Source Of Sulphur, Carl R. Christiansen Jan 1952

Marcasite From The Upper Mississippi Valley Zinc Area As A Source Of Sulphur, Carl R. Christiansen

Professional Degree Theses

"Sulphur is a mineral material which is as basic as steel to our industry and economy. This fact is not generally realized because it is seldom seen, but it goes into the manufacture of practically every article of clothing we wear, and the food we eat is dependent upon it. Most items we produce require the use of sulphur at some stage of their manufacture. The consumption of sulphur has been increasing rapidly and is now far above its World War II peak. Production has been greatly increased but has been unable to keep up with the increasing demand. This …
