Essentials Of Rock Drill Design, Lister Merriken Cummings

Professional Degree Theses

"The earliest history of the rock drill is obscure and only fragmentary evidence concerning it is recorded in the Patent Office. However, no other tool has played a more important part in mining and excavating work. There have been two general classes of pneumatic rock drills -- the reciprocating, or piston machine, and the hammer drill. Fowler played an important part in the early development of piston machines, and the first hammer drill was made in about 1895 by a man named Brothers"--History, page 1.

The Application Of Fluid Level Measurements To Oil Wells In Kansas, Charles Calvert Rodd

Professional Degree Theses

"The mechanics of determining fluid levels and a knowledge of the depth-to-fluid in a well are matters of general interest. To the oil-producer, however, such information is of value only as it may affect the operation of a well or reservoir"--Uses of Fluid-Level Measurements, page 9.

The Clark National Forest Of Missouri, Walter A. Werner

Professional Degree Theses

"The question might logically arise as to the appropriateness of a thesis with a forestry title being submitted for an engineering degree. The writer has been connected with the United States Forest Service for the past four years in an advisory capacity on staff of the Forest Supervisor of the Clark National Forest, during which time he has found that the engineers and construction men have performed a major function in the development of the forest.

As the initial development consisting of lineal surveys, construction of roads and telephone lines, erection of fire lookout towers, planning and erection of ranger …

Red Glazes, Sidney Austin Peer

Bachelors Theses

"Red glazes are extremely difficult to produce on pottery except at relatively low temperatures, or under conditions which can only be regarded as largely accidental. For many years ceramists have demanded a red glaze maturing at cone 4. To produce this glaze, much time and research is required...The object of this study was to produce a commercial red glaze at cone 4 from different oxides in a base glaze of white lead and silica"--Scope of Investigation, pages 1, 7.

The Bloating Of Clays, Everett Walter Sharp

Bachelors Theses

"The effect of firing on clays in relation to volume is either a shrinkage, bloating, or no change whatso-ever. The reason for the shrinkage and the constant volume is well known, but the cause of the bloating has not as yet been determined. In some instances, as the use of fire clay brick in steel ladles, this property of bloating is desirable to a certain extent because this packs the brick lining in the ladle tightly after the first heat is poured in, and prevents the brick lining from floating out when the metal is poured. There is little or …

Constitution And Properties Of Manganese-Copper Alloys, James Harrison Jacobs

Masters Theses

"This work was undertaken because of the recently revived interest in the use of manganese as an alloying element. This revival of interest has been mainly due to the development of the process for electro-deposition of manganese by the U. S. Bureau of Mines. Prior to the work of the bureau of Mines there was no commercial source of high purity manganese. Manganese made by the electrolytic process contains less than .03% impurities, while manganese made by other methods contains as high as 3% impurities. The use of high purity manganese as a base for alloys should open up an …

The Volumetric Determination Of Alumina In Clays And Related Materials, David Ferdinand Boltz

Masters Theses

"The primary purpose of this thesis was to develop a direct method for the determination of alumina in certain silicates. The classical gravimetric procedure for the analysis of alumina in clays and related materials has often been regarded as being too lengthy and troublesome, especially when only the percentage of alumina was desired. The correct determination of alumina is undoubtedly one of the most unsatisfactory of the chemical constituents of siliceous materials, and therefore the development of a direct volumetric method for the determination of this constituent was made the main objective of this research, page [1].

Absorption Of Carbon Dioxide In A Bubble Plate Tower, William Arthur Enderson

Masters Theses

"Gas absorption, one of the chief operations of chemical engineering, has occupied investigators for a long time. Results of many experiments on the general subject of gas absorption has been published. However, relatively few data have appeared in the literature on the use of bubble cap towers for gas absorption although they constitute one of the three major classifications of absorption equipment. Bubble cap towers are used extensively in the petroleum industry. More performance data would increase the versatility of existing equipment"--Introduction, page 1.

The Effect Of Addition Agents In Grinding Portland Cement Clinker, Eugene Farrell Hill

Masters Theses

"In the dry grinding of most materials in a ball mill or similar apparatus, a degree of fineness is eventually reached when a noticeable decrease in the efficiency of grinding occurs. The degree of fineness where this phenomenon occurs, as measured by the specific surface of the material being ground, varies greatly with different materials. The accompanying effect in all cases, however, is the formation of a coating upon the balls; this coating in the case of cement adheres tightly to the balls and increases in thickness as grinding progresses after the initial "coating' fineness has been reached. Usually an …

Report On Tests Of Fenestra 1 1/2" Roof Deck Used In Horizontally Loaded Diaphragms, Authur Wilson, George Winter

CCFSS Library (1939 - present)

INTRODUCTION Increasing interest in recent years in the performance of roof systems acting as shear diaphragms to resist horizontally applied loads, as well as the vertical loads for which they are primarily designed, has led to an increasingly large number of tests of fullsize and scaled structures loaded in this manner. Fenestra, Inc., manufacturers of light gage steel floor and roof panels, has sponsored an extensive series of tests at Cornell University of floor and roof diaphragms composed of certain of their standard panel sections. The following report describes tests of shear diaphragms using three types of Fenestra 1 1/2" …

The Management Of Mobile Loading Units In Mines Working In Number V And Vi Seams Of Illinois And Indiana, Kirk Vern Cammack

Professional Degree Theses

"The knowledge and skill a face boss must have today is far beyond that required of even a mine foreman in hand-loading days. the care of material, the direction of the working force, the care and maintenance of equipment, the provisions for the safety of the men: all these are problems requiring the best of a boss' efforts. Because of these factors, the maintenance of a constant tonnage today rests almost directly on the section foreman. With this in mind, the following material has been prepared from the viewpoint of the face boss rather than from that of a superintendent …

Vocational Training Of High School Students In Electricity, Harry Fredrick Kirkpatrick

Professional Degree Theses

"At various intervals during the past five years I have had to justify my training program, not only to others but also to myself. After careful study and thought I am convinced that the objectives or purposes of the training program can be classified under four major headings: 1. Intelligent Self Direction... 2. Social Adjustment... 3. Work Habits... 4. Knowledge and Skills"--Part I, page 3-4.

Some Effects Of Geology On The Relation Between Rainfall And Run-Off, James Smythe Reger

Professional Degree Theses

"For the past five years, the writer has been engaged either directly or indirectly in the investigation of water supplies. Studies and observations made in Texas, Oklahoma, Colorado, and New Mexico, have brought to his attention the importance of geology to hydrology. This is especially true in reference to the relation between rainfall and run-off. In all texts and other publications relating to hydrology, the importance of geology to the subject is hardly more than mentioned. In the absence of actual stream flow records, many engineers resort to either the "direct comparative method", or the "rainfall percentage method", in estimating …

Construction Of A Concentrating Plant In The Waco Area Of The Tri-State District, William Henry Backer

Professional Degree Theses

"Company: St. Louis Smelting and Refining Company...The fee is some five hundred acres of mining land is owned by the company, and an additional two hundred acres is held under a mining lease. Drilling had proved the ore to occur in a dolomitic horizon and to contain from 3 to 12 per cent zinc and small quantities of lead. Early in 1930, some thought was given by the officials of the company to the erection of a concentrator to mill the ore from this acreage. During the ensuing months a basic flow sheet and type of structure were tentatively approved, …

Design Study Of A Three Span Continuous Tied-Arch Bridge, George Perry Steen

Masters Theses

"In this study of the continuous tied-arch bridge, having one main span and two equal side-spans, the following items are endeavored: (1) To set up the total internal work equations and to find the values of the unknown forces or redundants. (2) To compute to maximum moments for design and to complete the design of the super-structure for one bridge. Details, such as the gusset plates, rivets, connection angles, etc., are not designed; the effect of such being allowed in the design for dead load as a certain per cent for details. (3) To set up hypothetical conditions for other …
