The Correlation Of Kelly Ball Penetration Readings With Standard Slump Cone Readings For Concrete Made From Missouri Aggregates, James Claude Rives Jan 1957

The Correlation Of Kelly Ball Penetration Readings With Standard Slump Cone Readings For Concrete Made From Missouri Aggregates, James Claude Rives

Masters Theses

"The ASTM standard slump test as set forth in ASTM Designation: C143-52, has been used for many years in concrete construction tor measuring the consistency of plastic concrete. Slump tests taken in the laboratory are considered reasonably accurate; however, there are numerous disadvantages in performing these tests in the field; the most serious being the time required to make a test on pavement work. The standard slump cone method is also subject to personal differences in sampling, rigidity and smoothness of base, dampening the apparatus, filling the cone, rodding, raising the cone, freedom from jarring and selection of point to …


Separation Of Iron-Tin Alloys Using Gas-Solid Reactions, Carl Richard Bieling Jan 1957

Separation Of Iron-Tin Alloys Using Gas-Solid Reactions, Carl Richard Bieling

Masters Theses

"For years it has been a problem to the tin smelting, plating, and detinning industries to be able to separate iron from tin once they were associated together as described above. Due to the lack of a tin smelter in the United States in the past, and the abundance of tin scrap available, which had little value either for the iron content or the tin content in their untreated state, most interest was concentrated on seeking methods of separating this tin scrap into its two useful components, iron and tin, rather than deal with the problems of smelting tin from …

Thermal Conductivity Of Sodium Chloride Within The Temperature Range 375°K To 637°K, Paul E. Ohlsen Jan 1956

Thermal Conductivity Of Sodium Chloride Within The Temperature Range 375°K To 637°K, Paul E. Ohlsen

Masters Theses

"The transport of heat in dielectric solids is attributed entirely to lattice waves whereas in metals there is in addition a transfer by the flow of valence electrons. The thermal conductivity of a non-electrical-conductor is limited by a number of scattering processes giving rise to thermal resistances. Scattering results from impurity atoms and from vacancies and dislocations within the crystal structure and from the interaction of the lattice vibrations amongst themselves. Scattering also occurs at the boundaries of the crystal. The thermal resistance of an ideal crystal at low temperatures is due almost entirely to boundary scattering and at high …


The Thermal Conductivity Of Potassium Chloride At Elevated Temperatures, Wendell D. Miller Jan 1956

The Thermal Conductivity Of Potassium Chloride At Elevated Temperatures, Wendell D. Miller

Masters Theses

"The transport of heat in solids is attributed to the combined effect of the quantized vibrations of lattice points, or phonons, and the flow of valence electrons. In dielectric solids, the thermal conductivity is due almost entirely to phonons, while in metals the latter method preponderates. Scattering processes in dielectric solids, giving rise to thermal resistance, also serve to limit the thermal conductivity. Scattering results from vacancies, dislocations, interstitial atoms and phonon interaction. Crystal boundaries also function as scattering points and in crystals of small dimensions, this process is the most pronounced conductivity-limiting factor. At low temperatures the thermal resistance …


Investigation Of The Current Distribution On An Antenna In A Waveguide, David J. Freeman Jan 1956

Investigation Of The Current Distribution On An Antenna In A Waveguide, David J. Freeman

Masters Theses

"In a communication system composed of several networks and transmission systems, it is necessary for all parts of the system to be impedance matched so that medium energy transfer is possible.

One of the recent transmission systems which has been developed is the wave guide. With the advent of the wave guide the communication engineer is immediately faced with the problem of coupling existing systems and networks to his newly found mode of transmission.

Practically this coupling problem reduces to one of feeding radio frequency energy to the wave guide with some conventional transmission line such as a coaxial line. …

The Properties Of Cold Rolled - Stress Relief Annealed 70-30 Cartridge Brass, Robert F. Hartmann Jan 1955

The Properties Of Cold Rolled - Stress Relief Annealed 70-30 Cartridge Brass, Robert F. Hartmann

Professional Degree Theses

"Because of the possible commercial application of the proposed treatment of 70-30 brass, this work was undertaken. In addition, the data resulting from this work will result in a better understanding of the treatment of brass.

The objectives of this work were as follows:

  1. Determine if higher strength and better spring properties can be realized from a process for commercial 70-30 cartridge brass wherein the regular recrystallizing anneals between rolling reductions are replaced by stress relief anneals.
  2. Determine if it is possible, using the above process, to produce essentially fully recrystallized metal with an average grain size below that usually …


Aspects Of Quality Control In Foreign Manufacturing Operations, Erich Rolaff Jan 1955

Aspects Of Quality Control In Foreign Manufacturing Operations, Erich Rolaff

Professional Degree Theses

"The present thesis is being written to illustrate some aspects of quality control in foreign manufacturing operations; that is, foreign to the United States. It is obvious that the conditions and probable variations from U. S. practice in any manufacturing industry will vary tremendously according to the industry under review. In the present case we shall be dealing with manufacturing operations involving the production of so-called "dry cells" and "dry batteries", and to a somewhat lesser degree with the production of projector arc carbons for use in motion picture theater projection. It will be, therefore, helpful if a brief history …


Preparation And Separation Of Metallic Chlorides, Norbert Felix Neumann Jan 1955

Preparation And Separation Of Metallic Chlorides, Norbert Felix Neumann

Doctoral Dissertations

"The use of chlorine and chlorine compounds as metallurgical reagents has long been known to the metallurgical industry. Recent developments in corrosion resistant metals and alloys as well as new equipment and techniques have led to a revival of chlorine processes. Many of the objections to the use of chlorine in metallurgical operations have been overcome and many are being reconsidered, as evidenced by the new processes in which chlorine and chlorides are the primary reagents. The Betterton process employs chlorine or lead chloride for the dezincing of lead. Ductile zirconium and titanium have been made by reducing their chlorides …


The Thermal Conductivity Of Sodium Chloride At Elevated Temperatures, Howard Martin Brown Jan 1955

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 …


A Study Of Tunnel Demolition By Hasty Methods, Richard Lee Bullock Jan 1955

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 …

Hydrogen Overvoltage On Titanium, Sheng-Tai Shih Jan 1954

Hydrogen Overvoltage On Titanium, Sheng-Tai Shih

Doctoral Dissertations

"The hydrogen overvoltage has been defined as the difference between the potential of the working electrode (cathode) and the theoretical reversible value for the same solution. This definition brings out the difficulty involved in the measurement of the "theoretical reversible potential for the same solution” as the potential of the hydrogen electrode in such a solution is usually different from the value of a standard reversible hydrogen electrode, for which the activity of hydrogen ions is set as being “1” and the potential arbitrarily set as being “0”. Besides, it is sometimes necessary to add addition agents to the solution …
