Preliminary negotiations were started with Chance Vought Aircraft Company in March 1953, and the wind tunnel calibrations were started in October 1954. Between those dates all design, installation drawings, and construction were completed.

The data used in preparing this thesis were taken from daily records, records of conferences, personal records, correspondence …

Further Studies Of Vapor-Liquid Equilibria Of Methanol-Ethylene Glycol-Water, Herbert Benjamin Sachs

Masters Theses

"The freezing points of the ternary system methanol-glycol-water have been investigated by Conrad, Hill and Ballman. The vapor-liquid equilibria of the same system was studied by Sjoberg. These investigations were carried out to determine the properties of the system relative to its possible use as an antifreeze mixture.

Since Sjoberg's work in 1948, the improved Othmer equilibrium still has been introduced for vapor-liquid experimental determinations. It is therefore the purpose of the present investigation to evaluate the use of this still, compare results with those obtained by Sjoberg, and analyze ternary mixtures for the entire range of glycol concentrations.

Mechanical Vibration Of Vacuum Tubes, Jerry Dale Swearingen

Masters Theses

"Since the beginning of the art of vacuum tube building, vacuum tube engineers have been faced with many mechanical problems as well as electrical problems.

Early mechanical problems were comparatively small because most of the tubes were used in stationary apparatus where little or no vibration was envolved.

As time went on, vacuum tubes were placed in portable equipment and this useage established the need for a tube that was mechanically strong enough to give reliable electrical behavior where the tube was subjected to considerable vibration….

Recently it has been shown that vacuum tubes operating in the instrument cabins of …

The Thermal Conductivity Of Sodium Chloride At Elevated Temperatures, Howard Martin Brown

Masters Theses

"The thermal conductivity of solids has been attributed to a combined effect of the quantized vibration of the lattice points, called phonons, and the flow of valence electrons. In nonconductors the thermal conductivity is due almost entirely to phonons, as was shown by Debye, whereas in metals the conductivity is due mostly to the flow of valence electrons. After Debye, Peierls calculated the lattice conductivity at elevated temperatures using quantum mechanics and demonstrated that it is proportional to 1/T. There are not enough data available to substantiate any theory but what data there are seem to indicate a mixed conductivity …

Nanbo₃ - Batio₃ - Basno₃ Ceramic Dielectrics, William Dean Mckee

Doctoral Dissertations

"A. The Problem.

The purpose of this investigation was to form by ceramic processes a number of compositions in the ternary system NaNbO₃ - BaSnO₃ - BaTiO₃, to determine certain dielectric properties of these, to study them by means or x-ray diffraction, and to determine the extent or correlation possible between the compositional variation of dielectric properties and the x-ray results.

Compositions investigated contained 50 mole percent or less BaSnO₃. Materials and methods of forming were chosen with the intent that the final bodies should be pure oxide compositions as represented in the ternary …

A Study Of Titanium Diffusion Coatings By X-Ray Fluorescent Methods, Alan Bernard Burgess

Masters Theses

"As the only previous determinations of the chemical composition of the titanium coatings had been analyses of the average composition of the entire coating, the determination of the variation in chemical composition throughout the coating was suggested. From this information, it was proposed that a better insight might be gained as to the extent and mechanism of diffusion in the coatings. It was also hoped to correlate the results with concurrent work being done on the phases present in the titanium coatings. From this correlation, it might be possible to show which phases are responsible for the desirable properties of …

Solution Of Some Chemical Plant Problems Associated With The Manufacture Of Insecticides, Lawrence Ralph Hinken

Professional Degree Theses

"This thesis describes the solutions of a variety of developmental, production, and general engineering problems encountered in a chemical plant. This plant produces resins, solvents, and insecticides. Most of the problems considered here are patented or are of a secret nature. These details are, in the main, satisfactory temperatures, molar ratios, times of reaction, and space-time data. Therefore, it is the purpose of this discussion to be general but, in the main, to give the outline of the thinking which derived these solutions. Some of these solutions were of minor economic value, some were vital to the success of the …

Design Of A Precast Concrete Deck Girder Highway Bridge, Robert V. Gevecker

Professional Degree Theses

"In the Fall of 1951, as a result of an agreement between the Portland Cement Association and the Missouri State Highway Department, with the approval and good wishes of the United States Department of Commerce, Bureau of Public Roads, the State Highway Department embarked on a program to design and construct several precast, prestressed, and precast-prestressed concrete highway bridges"--Introduction, page 1.

The purpose of this extensive program being to indicate to State Highway officials and other interested parties the advantages of these types of construction. In the words of Mr. S. W. O'Brien, District Engineer for the Bureau of Public …

A Model For X-Ray Scattering From A Free-Volume Liquid, Charles A. Hewett

Masters Theses

"Investigation of the diffraction of x-rays by liquids was begun soon after the well-known work of Friedrich, Knipping, and Laue proved to be of value in supplying information as to the arrangement of atoms in crystalline matter. Friedrich in 1913 reported x-ray diffraction patterns of Canadian Balsam, paraffin, and amber; three years later Debye and Scherrer, in their work on benzene, (among other liquids investigated) showed that the diffraction phenomenon exhibited was one of interference. Still later, in 1922, Keesom and de Smedt reported similar investigations carried out on argon, nitrogen, and oxygen in the liquid state, the results of …

A Study Of The Emission And Absorption Spectra Of Nacl And Kcl Between 100 A And 1000 A, Paul Henry Blackmon

Masters Theses

"This investigation was begun with the idea of obtaining the emission and absorption spectra of NaCl and KCl in the region between 100 A and 1000 A. From these data, it is hoped that useful information concerning the energy levels of these two substances may be obtained.

The vacuum ultraviolet region is rather difficult to investigate because of the necessity of removing all air, lenses and other absorbing material from the light path. Many writers have enumerated the problems involved and some have indicated that much work still needs to be done in the vacuum ultraviolet.

In order to do …

Mechanism And Measurement Of First Stage Graphitization In White Cast Iron, David S. Gould

Masters Theses

"The original object of this thesis was to ascertain if coercive force measurements could be used for the determination of degree of malleablization in malleable iron. Since first stage graphitization was involved, it was only natural that an interest in the mechanism of first stage graphitization developed. The investigation which resulted from this interest was done primarily for the edification of the author, however it was subsequently deemed of enough importance to be included in this thesis. For this reason the thesis may appear at times to deviate from the original objective"--Preface, page iii.

The Velocity Of Ultrasonics In Liquids, Mack A. Breazeale

Masters Theses

"In acoustics the term ultrasonics is used to refer to those frequencies which are above the range of human hearing; that is, frequencies above approximately 20,000 cycles per second. Since the laws of sound which are valid for the audible range are also valid in the ultrasonic range and since the wave length of ultrasonics is much shorter than that of audible sound, ultrasonic has proved very valuable in the calculation of both the velocity and the absorption coefficient of sound in various media. This is especially notable in the case of liquids, where the velocity of sound is much …

A Fundamental Study Of Clay Drying Using Ware Of Large Cross Section, Robert F. Grady Iii

Masters Theses

"The drying of clay has been studied extensively in the past by many investigators, some of whom attempted to relate this information to the structure of clay and thereby develop a more vivid picture, while others studied the mechanism of drying in its own right in order to present a useable theory that would allow improvements in the drying operation.

At present the literature is unable to present a theory of the mechanism of drying that is sufficiently general to cover the observed aspects of clay drying. Many and varied mechanisms are presented, but correlation is seldom completely evident between …

An Investigation Of Continuous Steel Beams In The Plastic Range, Robert Adams Shoolbred

Masters Theses

"The purpose of this thesis is to investigate the action of beams in the plastic range. The test specimen will be a 4WF 13 structural shape continuous over three supports having equal span lengths of seven feet. Three types of loading were chosen. The first loading will be concentrated in the center of each span. The second loading will be a concentrated load in the center of one span only. The third loading will be the settlement of the two end supports until a plastic hinge forms at the center support, then the two spans will be loaded with concentrated …

Horizontal Pressures On Retaining Walls Due To Line Surface Loads, John B. Heagler

Masters Theses

"Among the oldest types of structures with which engineers have had to deal are those which serve to laterally restrain masses of earth, or to prevent earth embankments from assuming their natural angle of repose. This is necessary where space is limited or the natural slope would encroach upon other property. These structures, usually called retaining walls, are subjected to forces, both lateral and vertical due to the pressures exerted by the backfill material and any loads imposed on the backfill material. The first step in the design of the retaining wall is to determine the magnitude, position, and line …

Testing Of Missouri Shales For Light Weight Aggregate Production, Jerry D. Plunkett

Masters Theses

"The original objective of this investigation was to determine by testing those clays, shales, and loesses occuring in Missouri in large deposits (over 15 feet in thickness with little overburden), which would be suitable for the production of light weight aggregate. The second objective was to investigate the mechanism of bloating as related to the physical and chemical properties of the above materials, and by using these relationships cause clays which do not naturally bloat, to bloat using some addition. The use of additives would permit the economical use of material closer to the market in many instances.

After the …

Deposition Of Metallic Coatings From Fused Salt Baths, Andrew Hessler Larson

Masters Theses

"This thesis is the result of an investigation undertaken to study some of the important factors affecting the deposition of metallic diffusion coatings on other metals immersed in a fused salt bath….

There are many methods which have been devised to obtain diffusion coatings on various metals. One which is quite well known and used commercially is the process of “chromizing” which produces a diffusion layer if chromium on another metal. One method of “chromizing” consists of immersing the specimen to be coated in a mixed chloride fused bath containing chromium metal flakes. Another method consists of packing a low …
