Cellulose Pellets, John J. O'Neill Jr.

Professional Degree Theses

"This thesis describes the development of a new process for the manufacture of spherical particles of cellulose, regenerated from cellulose zanthate.

An electric equipment manufacturing company advised the author’s company that it had developed a device that required uniform spheres of regenerated cellulose having a diameter of about 75 to 100 mils. This company reported that it had developed a process for the manufacture of the cellulose particles but that the spheres produced by the process were not uniformly spherical. The equipment manufacturer considered that the functioning of the new device could be improved if the cellulose particles could be …

The Completion, Adjustment, And Operation Of A Grazing Incidence Vacuum Ultraviolet Spectrograph, William Clinton Johnson-Chamberlain

Masters Theses

"Most gases, and particularly oxygen and nitrogen, are nearly opaque to radiation in the region from about 1800 Å downward to about 2 Å and hence, for spectroscopic work in this region, the removal of these gases is mandatory. Popular usage generally refers to the range mentioned above as the vacuum ultraviolet. That there remains much experimental work to be done in the vacuum ultraviolet has been pointed out by Boyce in his exhaustive survey of vacuum ultraviolet spectroscopy. In order to fill in some of these gaps, Mr. L. H. Chapin, in the, spring of 1950, undertook the construction …

Uses And Advantages Of Short Period Delay Blasting Systems In Mining And Quarrying, Irving C. Falk

Masters Theses

"One of the most recent developments in blasting practice is that of applying the principle of short period delay electric blasting. In this type of electric blasting, instead or having all holes fire at one time, each hole or group of holes is a shot in itself. To provide a short period delay, of a few thousandths of a second, between each hole or group of holes, either millisecond (split-second) delay electric blasting caps or a suitable delayed action blasting switch may be used.

Short period delay electric blasting systems were originally developed for use by quarries in or near …

The Polarographic Determination Of Germanium, Herbert L. Bowkley

Masters Theses

"The purpose of this investigation was to study the polarographic behavior of germanium in various aqueous solutions. In addition to the simple polarographic behavior of germanium some attention was given to the applications or polarography for the development of an anlytical [sic] procedure for its quantitative determination in zinc ore concentrates and spelter fume materials"--Introduction, page 1.

An Ecological Study Of The Foraminifera Of Mason Inlet, North Carolina, Daniel N. Miller Jr.

Masters Theses

"Mason Inlet. North Carolina is a lagoonal marsh area with warm-temperate water, the salinity ranging from fresh to salt water. Nine collecting stations comprise an ecological gradient across the environment.

Forty-two species of foraminifera are recorded from the inlet, ranging in their affinities from brackish water to open-sea facies. Several extensions of range are recorded both northward and southward.

Substratum conditions apparently control the distribution of foraminifera within the inlet. Clean, fine sand provided the largest faunal populations. A depauperate assemblage was found in an inorganic, argillaceous substratum. The largest population of arenaceous forms was found at the channel through …

The Transformation Of The Aluminum-Zinc Eutectoid Alloy At Subcritical Temperatures, Thomas Joseph Burke

Masters Theses

"Interest in the mechanism of the austenite eutectoid transformation in iron-carbon alloys, especially as produced by the isothermal sub-critical techniques introduced by Davenport and Bain, has resulted in the application of similar heat treatment studies to the eutectoid transformations in other alloy systems. The study of the eutectoid transformation is of both fundamental and industrial interest because past experience has shown that these studies yielded much information concerning the nature and mechanism of the changes in eutectoid alloys during the decomposition of the phase stable at high temperatures and has also contributed much toward the development of new properties to …

A Study Of The Dissolution Of Titanium In Acids With Emphasis On Hydrofluoric Acid, Ping-Chao Chen

Doctoral Dissertations

"Titanium is practically a new metal. Although it was discovered by W. Gregor in 1791, the pure metal was not prepared until 1910 by M. A. Hunter, and it is only very recently that tremendous interest has been focused on this new metal, as evidenced by the activities of numerous leading laboratories and pilot plants.

The reasons that Ti is gaining increasing attention may be attributed to the natural abundance of Ti ores in reasonable concentration and, what is more important, to its unusual combination of physical and chemical properties. According to F. W. Clark’s classical geochemical data, Ti amounts …

Efficiency Studies Of The Effect Of Moisture On The Power Consumption Of Mine Scrapers, Georges J. Vigier

Masters Theses

"Many years of practice have resulted in the standardization of several types of scrapers which are now commonly manufactured for use in mining. Although experience has brought out much information on scraping operations, no systematic studies of the efficiency of mine scrapers have been carried out before the experimental works done in the last few years at Missouri School of Mines and Metallurgy. "Purpose of Problem": The purpose of this present study is to consider the effect which moisture in the muck has on the efficiency as regards power consumption and amount of material scraped, of different types of mine …

The Economic Spacing Of Contraction Joints In Reinforced Concrete Pavements, Wilbert Frederick Wegener

Masters Theses

"Structurally, there are two types of joints used in concrete pavements: (a) the tied, or permanently-closed joint; and (b) the open or free type of joint. The permanently closed joint utilized tie-steel of some form to keep the joint from opening. Usually, this steel is in the form of short individual bars extending across the joint and bonded to both slabs (designated as "tie-bars") or in the form of distributed reinforcement. The remaining method of classification, that of refering [sic] to the joint purpose, gives the expansion joint, contraction joint, and warping joint. An expansion joint is, as the name …

A Study Of Mine Scraper Efficiency On Materials Of Different Specific Gravities, Kermit Guy Rowley

Masters Theses

"The purpose of this study is to determine the effect that the specific gravity of the material scraped has on the power consumption and the efficiency of the common types of mine scrapers. As scraper weight, rope speed, and moisture content of the muck are important factors affecting the power consumption and efficiency, these variables are the ones considered for each type scraper. Two materials of different specific gravities are used in the study with an equal number of tests run on each material"--Introduction, Purpose of Problem, page 2.

The Precipitation-Runoff Relationship On The Grand River Basin Of Missouri And Iowa, J. Kent Roberts

Masters Theses

"In the study of a drainage basin which is to be utilized for water supply or water power, there is frequently a dearth or complete lack of runoff data, though precipitation data are almost always available. The Water Resources Branch of the United States Geological Survey maintains gaging stations on various streams and runoff records from these streams are available from their publications and offices. Many of these runoff records cover a considerable number of years, and are entirely sufficient for use in an analysis of any drainage basin covered by such data. Some of these gaging stations have not …
