Series Capacitors, Emcet Bilgeer

Masters Theses

"Static capacitors as an element of transmission and distribution circuits first appeared in the form of shunt capacitors. These shunt capacitors were primarily used in power factor correction. They can be regarded as a load in the circuit which draws a loading current. This loading current fleeing through the reactive line produces a voltage rise, thus reducing the voltage drop between sending and receiving ends. This phenomenon helps the voltage control of the feeder as well as power factor correction. The disadvantage of the shunt capacitor is its inflexibility. The shunt capacitor is connected across the line; hence the voltage …

Precise Lattice Parameter Determinations Of Diamond Silicon And Germanium By The Asymmetric Method, Esrefettin Zeki Aka

Doctoral Dissertations

"The construction of the apparatus for production of powder patterns at a definite temperature and the technique for evaluation of x-ray powder patterns by the asymmetric method are described in detail, and the mode of error elimination is discussed.

A new scanning device is designed for use in x-ray diffraction work.

A modified method is described for the determination of densities of solids, which eliminates some of the difficulties interfering with other similar methods thus far proposed. Formulae are derived for the calculation of density as well as for reduction of density at a desired temperature.

The following conclusion are …

Relationship Of The Overall Transfer Coefficient To The Factor In Ammonia Absorption, Ivan Lee Gray

Masters Theses

"Gas absorption has an important role in chemical and allied industries. It is used to separate one of a group of constituents from a gas stream. Poisonous or obnoxious gases may be removed from the gaseous waste products of chemical plants by absorbing them in suitable solvents.

Many investigations have been carried out and references too numerous to list have appeared in the literature on the general subject of absorption.

In all of this work one of the usual methods of reporting results has been to express the capacity of a piece of absorption equipment as an overall capacity coefficient …

A Survey Of Acidity In Drainage Waters And The Condition Of Highway Drainage Installations, James H. Havens, James L. Young Jr., Harvey J. Field Jr.

Kentucky Transportation Center Research Report

Every creek gulley and raw interrupted by roadway fills and embankments must be provided with an adequate drainage conduit under the pavement. If the natural drainage is impeded or the conduit is not functioning properly, impounded water over-runs the pavement, seeps through the fill, and eventually disintegrates the section or reduces its stability. The topography in Kentucky, through varied sectionally, requires on the average, one cross-drain for every thousand feet of roadway. Obviously, these drainage structures are of considerable economic importance in the highway program, not only from the standpoint of initial construction costs, but also from consideration of the …

Test 454: Dodge Power Wagon T137, Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary. All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University. Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

Four Papers On The Performance Of Thin Walled Steel Structures, George Winter, Warner Lansing, R. B. Mccalley Jr.

CCFSS Library (1939 - present)

“The investigations reported in the four papers were carried out under the auspices of the Engineering Experiment Station of Cornell University, Dean S. C. Hollister, Director, and in the School of Civil Engineering, Professor W. L. Malcolm, deceased, and Professor N. A. Christensen, Directors.

They are part of, or related to, an extensive investigation of thin-walled steel structures sponsored jointly by the American Iron and Steel Institute and Cornell University, of which Professor George Winter, Head, Department of Structural Engineering, is in active charge. On the part of the Steel Institute the work is directed by the technical subcommittee of …

Czarina Mine, Butte, Montana, Prodyot K. Das

Bachelors Theses and Reports, 1928 - 1970

The Czarina mine operated for a short time during the last Great War, lies in the southwestern corner of the Butte mining district of Montana. This area was worked during the extensive silver mining in Butte during the 1890's, and was prospected from time to time in later years. The orebody of the mine consists of fissure fillings of manganese mineral oxidized to a certain depth, in a fracture zone of the Boulder Batholith.

Mineralization Of The Bonanza Mine, H. M. Callaway

Bachelors Theses and Reports, 1928 - 1970

The Bonanza mine of the Emery mining district in Powell County is on the largest veins in the area, and is developed to a depth of 680 feet by an incline shaft following the dip of the structure. Sulfide ores carrying gold and silver values are mined throughout the area which is easily accessible by road from Deerlodge, Montana, ten miles west of the district.

Importance Of Unconformities To Oil Occurrence In Montana, Robert E. Evenson

Bachelors Theses and Reports, 1928 - 1970

Although the majority of geologic structures in Montana have been tested in the search for petroleum, only a few have been found to contain commercial quantities of either oil or gas, and with each successive dry hole, producers are becoming more and more wary of investing capital in new wells located on structural features alone. It is apparent that if new oil and gas fields are to be found in Montana, exploration must be done on the basis of some­thing other than structure, or combined with structure.

Fauna Of The Pilgrim Formation Of The South Boulder Creek Area In Southwestern Montana, John T. Eastlick

Bachelors Theses and Reports, 1928 - 1970

This paper, a study of the fauna of the Pilgrim formation at South Boulder Creek in southwestern Montana, represents a laboratory study of the fossil specimens collected by Dr. Alvin Hanson during the summer of 1949. The scope of investigation includes identification and classification of the faunas, their stratigraphic relationship and zonal subdivisions.

Foraminifera From The Colorado Shale Near Sunburst, Montana, Frank R. Reynolds

Bachelors Theses and Reports, 1928 - 1970

One of the many secrets which planet Earth has jealously kept from its inhabitants is the microscopic fossil form known as the foraminifer. It hides in common shale, awaiting the patient and painstaking searcher. In furthering the study of the foraminifera of the Colorado group of for­mations in Northern Montana_, the United States Geological Survey has collected several suites of shale samples from the Sunburst Dome, five to ten miles south of the Canadian border and twenty-five miles north of the city of Shelby, Montana_.

A Study Of The Effect Of The Maximum Melt Temperatures Upon The Degree Of Supercooling Of Gallium, Wilfred E. Nagel

Bachelors Theses and Reports, 1928 - 1970

If, in a system at a giv­en temperature, there should occur a decrease in free energy and this decrease does not take place, then the resulting condition of the system is termed supercooling. A common example of the phenomenon is found in the liquid-to-solid transition of many substances, when the temperature of the liquid may be lowered below its freezing point without solidification. Similar phenomenon occurs in the gas-to- liquid, gas-to-solid, and polymorphic transformations.

Fauna And Stratigraphy Of The Meagher Formation At Three Localities In Southwestern Montana, William J. Van Matre

Bachelors Theses and Reports, 1928 - 1970

In the past 75 years, the scenic area about the head­waters of the great Missouri River has attracted the atten­tion of many leading stratigraphers and paleontologists; for in this area bountiful outcrops of Paleozoic fossil horizons are available for study and correlation.

Mottling In The Meagher Limestone, Ronald J. White

Bachelors Theses and Reports, 1928 - 1970

The middle Cambrian Meagher limestone of southwest Montana is characterized by mottled members that are finely crystalline in the tan part and microcrystalline in the dark matrix. As seen in the literature, similar mottled limestones are thought to be an arrest­ed stage in the dolomitization, or alteration of limestones.
