Ceramic Properties Of The Clays Of The Polo Gas Field, Clarence Arthur Lambelet

Masters Theses

"In Western and Northwestern Missouri there exist many natural gas fields of such limited size and of such great dispersion that it is not economical to utilize their products by the construction of pipe lines to consuming centers. Thus a large source of natural wealth is lying idle. This wealth could be utilized, however, if some manufacturing process requiring large amounts of fuel were located in the vicinity...The availability of fuel is the reason for interest in the area, though an investigation should be made to assure the quality and quantity of the fuel in any selected area. the adequacy …

Prospecting, Developing, And Mining Bentonite Deposits, John Patrick Rasor

Masters Theses

"Clay and clay-like minerals are mined in many localities for a large number of uses. Most of these mines are small, seasonal operations. Common practice in these types of pits is to strip and mine clay from shallow overburden depths without the aid of careful prospecting and developing, and with little or no engineering technique. Bentonite deposits which must be continuously mined at tonnages from 5,000 to 7,500 tons per month require that the entire project be carefully planned and engineered so suitable equipment may be obtained and operational cost minimized. This thesis is concerned with the prospecting, developing, and …

Flotation Of The Oxidized Ores Of Zinc, Fred Henry Bunge

Masters Theses

"There is no satisfactory method of concentrating the finely disseminated oxide ores of zinc. Gravity methods of concentrating such ores may be used for coarsely crystalline materials in which the zinc material is free at approximately 10- to 35-mesh or coarser. In addition, gravity methods of concentration do not give a satisfactory separation on those ores in which the gangue mineral is small. As a result there is need for a method of beneficiating various deposits of oxidized zinc ores. The two commercially important oxidized zinc minerals under consideration are smithsonite, the zinc carbonate and hemimorphite, frequently referred to as …

A Study Of Mine Scraper Buckets And Their Efficiency, Austin Bond Clayton

Masters Theses

"The use of power drawn scrapers, often called "slushing", for the moving of ore, stops filling, and waste rock has become standard practice in many mining operations. Several types of scrapers have been developed by practical application or by trial and error methods. However, a direct comparison of these scraper types under identical conditions has not been noted in a review of literature on the subject of mechanical loading. Written inquiries to authorities on scraping practice have brought replies that no previous comparisons of scraper types on a modal scale have been attempted. Therefore, the following thesis problem was set …

Nebraska Farm Building Data For Panhandle Counties Taken From U.S. Census, R. M. Loper

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The Material given on the following pages was selected from united States Census data for the years indicated.

It has been arranged to permit analysis and comparison of building trends since 1900, both in the state and in individual counties. Such a study often reveals areas in which effective educational programs could be develol)ed and indicates the phases of such programs which are needed most.

Unfortunately, complete 1945 figures are not available yet, but space has been left for them so that they may be added when released by the Census Buroau.

Nebraska Farm Building Data For North-East Counties Taken From U.S. Census, R. M. Loper

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Fluctuation in the number of farms since the start of the century reflects economic trends, drouth effects and the results of increasing mechanization, particularly since 1935.

The 1945 figures also show the influence of land taken out of production for use as air bases, ordnance plants and ammuition depots. No doubt some of this will be returned eventually to agricultural uses. Since the buildings were removed from this land during the war some new sets probably. will be constructed when individual ownership is obtained again. Such activities present excellent opportunities for developing farmsteads efficiently and attractively arranged; buildings designed to …

An Outline Of Prospective Research For The Highway Materials Research Laboratory, L. E. Gregg

Kentucky Transportation Center Research Report

The following outline and comments are intended to serve as a general guide for future endeavors of the Highway Materials Research Laboratory, and as a basis for discussion among Members of the Research Board. For the most part these will provide a structure within which the details of individual projects may be classified and from which the subject matter for separate studies may be drawn. By preparing such a plan, but recognizing the need for deviation when unforeseen situations arise, it is hoped that the possibilities for maintaining a comprehensive but well integrated research program may be enhanced.

Summary Report Of Concrete Investigations In Research Projects C-1, C-2, C-3, And C-17, S. T. Collier

Kentucky Transportation Center Research Report

The data presented in this report were obtained in laboratory investigations of concrete mixes, the majority of which were correlated with Highway Department field projects. Practically all of this information has been recorded in vast reports on individual studies, but here these are combined and summarized in order to facilitate comnarisons between the results from tests similar in nature, and to provide wider distribution of these results.

Of the four research projects considered three were devoted to tests on beam specimens prepared in the field and sent to the Research Laboratory for analyses. The fourth was purely a laboratory study …

Surface Impregnation Of Wood : Ii. Gaseous Impregnation Of Wood : Iii. Investigations On Submarine Decking : Iv. Investigation Of Marine Adhesives., Otto J. Mileti

Electronic Theses and Dissertations

This thesis presents results on methods used to produce a hard surfaced wood product. The methods involve the parting of the wood fibers on the surface by a special serrating tool, followed by surface impregnation and final curing. The serrations on the wood surface produce an artificial grain upon curing. A preliminary investigation was made to improve the rot-resistance of wood by gaseous treatment. Results of such treatments show some limited success with formaldehyde on yellow poplar and warrant further study. An investigation was made to find a substitute for teak wood used on submarine decking. A number of combinations …

Heat Transfer To Fuel Oil In Viscous Flow-Characteristics Of A Fin-Type Heat Exchanger., Boyd R. Abbott Jr.

Electronic Theses and Dissertations

A unit was constructed for the study of film heat transfer coefficients of a heavy fuel oil in viscous or streamline flow. The heat exchanger was of the shell and tube type, having extended longitudinal steel fins welded to the tube. Auxiliary equipment consisted of an oil pump, oil storage reservoirs, piping, and means for measurement of temperatures and oil flow rates. The unit was operated both as a fin type heat exchanger with the oil in contact with the finned surfaces, and as a straight tube and shell exchanger with the oil on the tube side. Oil flow rates …
