The Determination Of Particle Terminal And Transport Velocities, Bertram C. Raynes

Honors Theses

The movement of finely divided material in chemical process equipment is becoming the object of much present-day study. In industrial practice, the ability to predict the behavior of small bodies moving through a fluid medium or being moved by a fluid medium must be based upon data relating to physical properties of both the particle and the fluid; these physical properties should be those which can be readily determined.

A particle falling through a fluid medium will achieve a steady state velocity if it is allowed to fall until its acceleration becomes zero. This steady state rate of fall is …

The Effect Of Heat Aging Upon Silicone Rubber Compounds, Jonathan Rodney Learn

Honors Theses

Silicone rubber compounds are high temperature rubber-like materials consisting of silicone gum, a filler, and a curing catalyst. The filler is added to the rubber to give good molding properties and also good tensile strength and elongation. The data in this thesis shows that the compounds which had the best heat aging properties consisted of 100 parts of silicone rubber and 0.5 parts of' benzoyl peroxide as the curing catalyst, with titanium dioxide as the filler.

A Study Of The Differential Seperation Of Galena And Sphalerite, Wilfred E. Nagel

Bachelors Theses and Reports, 1928 - 1970

The smelting of complex lead ores is a difficult operation, especially when they contain considerable amounts of iron and zinc. When these ores are smelted, all of the zinc, which is valuable and well worth recovering, goes into the slag. With the advent of the flotation processes, and the ability of these processes to concentrate the lead and zinc minerals into separate products, the smelting of complex lead ores was to a great extent simplified.

The Christensen Sillimanite Deposit Southeast Of Dillon, Montana, Everett O. Bracken

Bachelors Theses and Reports, 1928 - 1970

The minerals sillimanite, kyanite, andalusite, dumortierite, and topaz comprise a group of minerals whose high alumina content and physical properties are particularly desirable in the manufacture of refractory products. Sillimanite is the least plentiful of the minerals of this group, and for this reason it is not used extensively at the present time. However, it would be very desirable to the refractory industry if a suitable domestic source of supply could be established.

Petrography Of The Chilhowee Group, Near Walland, Tennessee, George David Swingle

Masters Theses

Introduction: Time and the stratigraphic relationships of the Ocoee and Chilhowee groups have long been a problem in southern Appalachian geology. These rocks, now metamorphosed to varying degrees, outcrop over wide areas in the mountain region. Unfortunately, no one person has been able to study their problems in enough detail to unravel them and, as a result, many conflicting statements are in the literature.

Formations of the Ocoee and Chilhowee groups are largely composed of fine to coarse clastic sediments. In general, rocks of the Ocoee group lie to the southeast; those of the Chilhowee group to the northeast. The …

A Study Of Steric Inhibition Of The Pfitzinger Reaction, Robert Earl Stobaugh

Masters Theses

(From Introduction)

A survey of the Pfitzinger reaction reveals that little attention has been given to the steric factors likely to govern the course of the condensation; a major part of the research done has dealt with its value as a synthetic tool.

The primary purpose of this work was to add further information concerning steric inhibition in the Pfitzinger reaction; it was also hoped that the cinchoninic acids obtained might show physiological activity.

A New Method Of Measuring The Intensity Of The Zodiacal Light, Raymond Grenchik

Physics & Astronomy ETDs

The two theories that have been presented for the zodiacal light show that it is due to light scattered (and perhaps emitted) from an extensive lenticular cloud of particles lying in the plane of the ecliptic. The basic difference of the two theories is the position of the center of this cloud. One, the planetary theory, places the sun at the center of this cloud. The other, the atmospheric theory, places the earth at the center of the cloud.

The Chromatographic Separation Of Gilsonite, Harold Albert Bezzant

Theses and Dissertations

Separation of natural hydrocarbon minerals into their constituents non-destructively is a very difficult problem. A non-destructive analysis of the hydrocarbon minerals is essential to their wise utilization. Chromatography represents a non-destructive means of separating adsorbable substances non-destructively with a high degree of purity. The chromatographic separation is based upon the simple principle of the difference in adsorption affinity of compounds for a particular adsorbent. The chromatographic separation of gilsonite was, therefore, undertaken in an effort to prove that the adsorbable compounds of this hydrocarbon mineral could be separated by this simple non-destructive method. The first chromatographic columns of alumina, silica …

Application Of The Electric Furnace To The Melting Of Cathode Copper At The Tacoma Smelter, Alvin H. Nelson

Bachelors Theses and Reports, 1928 - 1970

In the field of copper metallurgy, the major chang­es effected in the original metallurgical scheme have been based largely upon the lowering in grade of copper ores, and the more particular demands of the fabricators of the metal. The former trend fostered the development of mineral beneficiation, which in turn caused the con­version from blast furnace to reverberatory furnace smelting.

A Cosmic Ray Experiment Using Nuclear Photographic Emulsions, Mercedes Merner

Physics & Astronomy ETDs

A "camera" containing thirty-six nuclear plates was carried into the upper atmosphere to an altitude of twelve miles by a free balloon flight. These plates were arranged in four groups separated by successively thicker layers of steel so that nuclear events under different amounts of matter could be observed.

After recovery of the equipment these plates were developed and examined under the microscope. Four plates were selected for intensive investigation, and data was collected on the tracks found in the areas examined.

In the first part of this report nuclear plate technique will be discussed in general together with the …

This property alone has more to do with the prominence of copper among useful metals then does any other.

The Casting Of Anodes For The Series System Of Electrolytic Copper Refining, Robert R. Kupfer

Bachelors Theses and Reports, 1928 - 1970

The electrolytic refining process, while usually considered an auxiliary process used in conjunction with pyrometallurgical extraction, deserves a special niche in the complex metallurgy of copper. The development of electrolytic copper refining, for example, is largely responsible for the prominence of the electrical industry. Conversely, it could be stated that the electrical industry played an important part in the development of the copper industry.

A Nuclear Magnetic Resonance Absorption Experiment, Richard Runge

Physics & Astronomy ETDs

In nuclear magnetic resonance absorption work, the detection of the absorption of energy by protons situated in a steady strong magnetic field and subject to a weak radiofrequency (RF) magnetic field is attempted. The protons are present in a sample placed inside an RF coil. A radiofrequency current, present in this coil, produces a rapidly oscillating magnetic field which is capable of supplying energy to the system of protons in the steady strong magnetic field. This absorption of energy by the protons alters their relative numerical distribution among the energy levels available to them.
