Foundations For Aquatic Oil Wells, Henry Emmett Gross

Professional Degree Theses

"During the past decade, man has found the courage to drill for oil at those forbidding locations which were made inaccessible by several feet of water. Some of the major fields of the world have been developed by this new manner of work, and others might have been added had the stage been set for the play. The most spectacular marine oil field development occurred along the Santa Barbara Coast of California from 1929 to 1931. It was the writer's good fortune to have been an assistant to Mr. Hans E. A. Gude, the field engineer of Pacific Western Oil …

Efficient Management Of Highway Projects Under State Administration, From The Point Of View Of The Project Or Resident Engineer, Jean Paul Bryan

Professional Degree Theses

"Efficiency in any project is an admirable attribute. It is even more than admirable in an undertaking designed for the spending of the taxpayer's money in which the lack of this trait is so liable to be interpretated [sic] as graft. It is necessary. After some eight years of connection with highway construction, a familiarity with inefficiency in the management of high projects under state construction is sufficient excuse, we believe, to warrant a dissertation of the opportunities for the practice of efficiency by those in direct charge of these project - the Project Engineers or the Resident Engineers, as …

A New Theory Of The Spalling Of Fireclay Products With Relation To Thermal Expansion, Robert Legrande Stone

Bachelors Theses

"There is one factor that is responsible for much of the failure of refractories in furnaces and other metallurgical processes and boilers, namely spalling. Many times this action has been the cause of roofs to cave in, side walls to slump, and bungs to fail. Consequently it is a factor that is of utmost importance. The erosion and slag effects are also of greatest importance to refractory stability. Spalling, as referred to refractories, is defined as the breaking or crushing of the unit due to thermal, mechanical, or structural stresses, presenting newly exposed surfaces of the residual mass. Taking the …

The Effects Of Sodium, Barium And Calcium Chloride Upon The Physical Properties Of A Whiteware Body, William Newton Coffman

Bachelors Theses

"The wide spread use of American kaolins and ball clays has been frowned upon by the majority of white-ware manufactures because the product resulting from their use in most cases has a color which is inferior to ware produced from English raw materials. This inferior color is generally attributed to the presence of a small amount of iron in the American clays. If some inexpensive chemical addition could be made which would eliminate the iron stain or in some way mask it, a wider market could be found in the white-ware industry for the domestic clays. One way to eliminate …

The Photobromination Of Azobenzene, Oden Cass Garst

The Effect Of Variations In The Rate Of Heating On The P.C.E. Value Of Clays, Kenneth Emerson Evans

Bachelors Theses

"Softening temperature of ceramic materials vary with the rate of heating. Recently much discussion has centered about the proper rate of heating of cones in the P.C.E. test. The most obvious reason for the discussion is that the cones are affected by the rate of heating when tested alone for softening temperature"--Introduction, page 1.

A Comparative Study Of The American Society For Testing Materials Spall Test And The Federal Specifications Spall Test, Justus Jordan Beinlich

Bachelors Theses

"Commercial brands of fireclay brick will be tested with both the American Society for Testing Materials and the Federal Specifications Spall Tests in order to determine whether the two tests are consistent in the indication of resistance to spalling. It is suggested that the properties of a refractory affecting thermal spalling are reversible thermal expansion, elasticity, heat transfer, plastic flow, and strength. It is hoped that it will be possible to explain the discrepancies that may arise in the results of this work in terms of the above physical properties or else find a reasonable agreement between the two tests"--Introduction, …

Study Of The Substitution Of Barite For Barium Carbonate In A Whiteware Body Suitable For Brick Manufacture, Charles Edward Achuff

Bachelors Theses

"Some years ago a method of manufacturing white brick from Georgia Kaolin and apatite rock was developed. This was successful for supplying an attractive white brick to the southern trade, until difficulties were encountered in securing apatite rock of sufficiently high grade to insure the continuance of manufacture of the brick...With the foregoing facts at hand, a study was made of the utilization of an auxiliary flux to replace the apatite rock. A commercial brick was developed, wherein eight (8) per cent of this flux, with forty-two (42) per cent potters flint and fifty (50) per cent Georgia Kaolin was …

The Replacement Of Calcium Carbonate With Calcium Chloride And Calcium Fluoride In A Whiteware Body, Charles Richard Rosenbaum

Bachelors Theses

"In the steel industry it is a common metallurgical practice to add fluospar sic (CaF₂), to a slag to render it more fluid. Ladoo states that the fluospar sic , thus added, forms eutechtics with the silica, alumina, calcium and barium sulfates, rendering them more fusible. The fluospar sic does not decompose, but forms solutions or eutechtics with other substances in the slag. He further states that calcium chloride (CaCl₂) has been used for this purpose but is apparently not as active, necessitating larger quantities per charge. It is also probably more expensive. Calcium carbonate (CaCO₃) is commonly used as …

The Effect Of Reheating Certain Fire Brick On Pyrometric Cone Equivalents, Francis J. Louney

Bachelors Theses

"In a recent survey of the refractories field, especially with respect to the softening point of fire brick, it was suggested to the author that the possibility of reheating certain fire brick, according to the specifications given by the American Society for Testing Materials, might produce a difference in pyrometric cone equivalent from that of the original or unreheated sample. At present, there is considerable lack of knowledge regarding the problem, as evidenced by the utter lack of literature on the softening point resulting from the reheating of fire brick"--Introduction, leaf 1.

A Study Of The Evaporation Of Organic Liquids And Mixtures Of Organic Liquids, George Walter Eckert

Masters Theses

"The purpose of this thesis is to make a study of the evaporation of organic solvents. The relative rates of evaporation of the single substances and binary and ternary mixtures are to be considered. A study of the changes in composition of binary and ternary mixtures that occur on evaporation are to be made. Information on the evaporation of organic liquids is important in relation to lacquers, and for that reason the solvents used in this work are liquids commonly used in making lacquers"--Introduction, page 2.

A Method For Increasing The Iodine Value Of The Saturated Fatty Acids, Richard Groves Holmes

Masters Theses

"The work covered by this thesis was undertaken with the idea of finding a method whereby unsaturated oils, of the drying type (those having iodine values of one hundred fifty or above), could be made from the saturated fatty acids. After an exhaustive search of the literature no evidence was found that this means of producing the unsaturated acids had ever been developed. Work has been done on the chlorination products of the fatty acids, the processes being covered by patents. No evidence however was given as to the possible structure of these compounds"--Introduction, page 1.

The Relation Between The Mean Molecular Weight And The Absolute Viscosity Of Lubricating Oils, John Isler Moore

Masters Theses

"Of all the properties required of a good lubricant the most important is that of the viscosity at the temperature of its use. Most lubricants consist of oils blended or compounded together in such a way as to produce an oil of a desired viscosity, falling in the special group of viscosities expressed by the Society of Automotive Engineers in their tabulations.

There have been several methods developed to enable the refiner to blend quickly and efficiently although Bell stated that the methods were largely that of trial and error. Herschel formed a chart for blending by the logarithmic rule …

The Public Health Engineer's Part On A Health Program, Walter Eric Casey

Professional Degree Theses

"In this work the Public Health Engineer should not be confused with the Sanitary Engineer as the term is commonly used today. The Sanitary Engineer is primarily a designer or builder. He is, in fact, a civil and hydraulic engineer specializing in a rather restricted field, confined for the most part to works relating to municipal water supply and sewage. The Public Health Engineer on the other hand is primarily a student and worker in the field of public health. The range of his activities is wider, and his training and knowledge are of essentially different character. It is not …
