Deposition Of Titanium By Gaseous Reaction, Louis John Reitsma Jr.

Masters Theses

"Previous investigations undertaken at the Missouri School of Mines and Metallurgy on the deposition of titanium involved the use of fused salt baths, aqueous solutions, and cementation processes. The fused salt baths produced satisfactory coatings on small metal parts. Some difficulty was encountered however, when the coating of large articles was attempted.

For this reason, it was decided to investigate the possibility of titanium deposition by the reaction of a volatile titanium compound with a metal surface. Two different compounds were proposed for investigation, (1) a lower chloride of titanium and (2) an iodide of titanium. The reaction with the …

A Study Of Tunnel Demolition By Hasty Methods, Richard Lee Bullock

Masters Theses

"The use of explosives to construct obstacles which impede the enemy or close his routes of communication has long been employed by our armies. They have developed fairly effective methods for destroying bridges, setting up road craters and constructing abatis. However, one phase of obstacle construction, that of tunnel demolition, has been neglected in that no procedures or methods have been formulated which will aid in the proper destruction of tunnels.

At the present time, under the auspices of the Department of the Army, The Missouri School of Mines and Metallurgy is conducting a research program on tunnel demolition. The …

A Study Of The Structure Of Titanium Diffusion Coatings On Iron And Steel, Pao-Jen Chao

Masters Theses

"The Problem of the Thesis: A series of experiments have been made in the Metallurgical. Engineering Department of the Missouri School of Mines and Metallurgy for the investigation of titanium diffusion coatings. The technique of applying the titanium diffusion coatings on iron and steel is still in the experimental stage. A few of the physical properties and chemical compositions of such coatings have been determined, but the structures have not yet been extensively studied. As the correlations of the structures and the desirable properties are valuable for improving the quality or titanium diffusion coatings on iron and steel, an investigation …

Morphology And Systematic Position Of Some Anomalinid Foraminifera, Billy G. Deaver

Masters Theses

"Morphological studies of the following species are the basis for a partial revision of the Family Anomalinadae: Anomalina acuta Plummer, A. midwayensis (Plummer), A. pseudopapillosa Carsey, A. vulgaris (Plummer), Anomalinoides pinguis (Jennings), Cibicides alleni (Plummer), C. beaumontianus (d’Orbigny), c. harperi (Sandidge), Cibicidina danvillensis (Howe and Wallace), Planulina correcta (Carsey), and P. dumblei (Applin); a description of Stensioina americana Cushman and Dorsey, discorbid foraminifer, is included for comparison. The classificatory position and incomplete content of the family are: Superfamily Discorbidea; Family Anomalinidae; Subfamily Anomalininae (revised) -- with ventral supplementary apertures: Anomalina , Planulina ; Subfamily Cibicidinae -- with dorsal supplementary apertures: …

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 …

The Preparation Of Titanium Tetrachloride From Rutile, Nalin Sen

Masters Theses

"In recent years, considerable interest has been shown in the manufacture of titanium metal because of its outstanding properties both physical and chemical. The commercial process for the preparation of metallic titanium, known as the Kroll process, consists essentially of the reduction of titanium tetrachloride with magnesium in an inert atmosphere to produce titanium metal with magnesium chloride as a by-product.

Since, titanium tetrachloride is the basic compound from which to prepare metallic titanium by the Kroll process, much thought has been given to the preparation of titanium tetrachloride from titanium ores such as rutile or ilmenite.

The present work …

An Analysis Of Selected History Tests Prepared For Use In The High School, Charles E. Reed

Masters Theses

The Problem and Its Background

The Scientific Movement in Education

It is a well-known fact that for several decades educators have been trying to place the educational profession on as scientific a basis as possible.¹ One outgrowth of this effort has been the “educational measurement movement.” This movement has involved widespread attempts to use objective techniques in solving educational problems, objective measures in obtaining educational data, and to use the data thus obtained as a basis for organizing educational plans and procedures. The importance attached to this trend has led, in some cases, to an undue, and occasionally, distorted …

The Closure Of Thin Wall Pressure Vessels, Archie W. Culp Jr.

Masters Theses

"The object of this thesis is to find various methods of closing thin wall aluminum cylinders. Such a closure must be strong enough, that when internal pressure is applied, ultimate failure will occur along a longitudinal element of the cylinder and not at the closure. Moreover, such a method must not only be mechanically sound, but it must be readily adaptable to mass production"--Introduction.

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 …
