The Economic Spacing Of Contraction Joints In Reinforced Concrete Pavements, Wilbert Frederick Wegener
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 …
Calculations Of Maximum Sag Of A Transmission Line With An Ice Load On One Span, Rodney A. Schaefer
Calculations Of Maximum Sag Of A Transmission Line With An Ice Load On One Span, Rodney A. Schaefer
Masters Theses
"An important problem concerning electric power lines is the calculation of the maximum sag occurring when there is an ice load on only one span. The object of this thesis is to determine a practical method for calculating the maximum sag of a transmission line, suspended on suspension insulators, with the aforementioned loading conditions. This paper is limited to the case where the supports of the transmission line are at equal elevations and all span lengths are equal"--Introduction, page 1.
A Study Of Cast Eutectic Structures By Means Of Optical And X-Ray Microscopy, John Stanton Winston
A Study Of Cast Eutectic Structures By Means Of Optical And X-Ray Microscopy, John Stanton Winston
Masters Theses
"The present research is the result of interest in two rather broad, and at first thought, seemingly entirely separate topics: the structure of eutectics and x-ray microscopy. D. Hanson in 1923 in his correspondence with Albert M. Portevin in regard to his article on the structure of eutectics states, "A point that always stuck him (D. Hanson) in examining eutectics was that one of the constituents always formed a continuous phase round the other one. The orientation of one constituent was either constant or varied in a uniform manner. What, however, was the condition of the 'enveloped' constituent, which formed …
An Experimental Study Of Crystallization In Opal Glass, William C. Rous
An Experimental Study Of Crystallization In Opal Glass, William C. Rous
Masters Theses
"Opal glasses are well known from use in such forms as ointment jars, lighting globes, wall panelling [sic], and decorative effects in glass vases. Cryolite, fluorspar, and sodium fluosilicate are used in varying proportions in most glasses of this type. Since little is known of the mechanism of crystallization in opal glass, there is a definite need of gathering further information on this subject. This information is of particular interest to the manufacturers whose products consist of this type of glass. Further information would aid in control of the characteristics desired and perhaps would allow a more economical control"--Introduction, page …
The Temperature Within A Homogeneous Plate Of Finite Thickness, Charles R. Remington
The Temperature Within A Homogeneous Plate Of Finite Thickness, Charles R. Remington
Masters Theses
"The object of this thesis is to determine by an analytical method the temperature within a homogeneous plate of finite thickness subjected to a constant temperature on one side and a periodic fluctuating temperature, expressible in a Fourier series, on the opposite side. This problem in periodic temperature changes has not, to the author's knowledge, been solved previously. The flow of heat in the problem is considered in only one direction, the x-direction. Flow in the other two directions is considered negligible, or zero. Periodic temperature changes in the earth are of importance. The temperature changes have been used by …
Flood Control With Retarding Basin Type Reservoirs In Meramec Basin, Missouri, Ilhan Kaya Ozbilen
Flood Control With Retarding Basin Type Reservoirs In Meramec Basin, Missouri, Ilhan Kaya Ozbilen
Masters Theses
"When rainfall occurs that provides more runoff than can be carried within the normal channels of existing streams a flood results. The excess water overflows the valley lands, invades developed areas, and causes destruction of property or, in extreme cases, loss of human life...Many structures are built to control water: Waterways of proper depth and width provide arteries of transportation; water controlled and discharged through water-wheels provides power; water may be caught in storage basins and distributed for irrigation or water supply; and water that is an actual or potential source of damage or danger to property or to human …

The second purpose of this study is to provide traffic classification and other data on a typical county system of rural roads. Today, many counties in the United States are faced with the problem of inadequate roads, due to the modernization of the American farm. While they realize this problem exists, may county governments have developed no organized method of studying and determining their needs...When the author …
Thermal Recovery Of Petroleum By Electrical Heating, Harold Roy Coffer
Thermal Recovery Of Petroleum By Electrical Heating, Harold Roy Coffer
Masters Theses
"It is the purpose of this investigation to study the feasibility of recovering oil from laboratory size cores by passing electric current through the formation. If a voltage of sufficient magnitude could be applied to the formation to cause a flow of current, the formation would be heated. This heat should stimulate the flow of oil. The expansion of any gas present in the core together with the formation of hydrocarbon vapors should provide sufficient expulsive force to drive oil from the core. The effect of power expenditure, the necessary voltages, the changes of conductivity and power factor of the …
Torque-Stress Relations In Bolts With National Fine Threads, Eugene Casper Chase
Torque-Stress Relations In Bolts With National Fine Threads, Eugene Casper Chase
Masters Theses
"Stresses, in bolts, caused by initial tightening have long been a problem to machine designers. To take care of these unknown stresses, produced by initial tightening, designers have used empirical formulas. These formulas originally used for National Coarse Threads, have been carried over into the field of National Fine Threaded bolts. No known tests have been conducted to determine whether or not these formulas hold in the initial tightening of Fine Threaded bolts. Initial tightening stresses may be caused by one of two ways. First, consider two flat ground plates to be held together by bolts to form a steam …
Principles And Practices Controlling The Use Of Earthmoving Equipment, Woodrow John Latvala
Principles And Practices Controlling The Use Of Earthmoving Equipment, Woodrow John Latvala
Masters Theses
"The purpose of this study is to show how the efficiency in earthmoving projects can be increased by the application of engineering principles. Efficiency can be increased by choosing equipment to fit the given set of conditions; and, having chosen the equipment, operate it at its maximum efficiency. In order to choose the right equipment it is necessary to study the conditions under which the equipment must operate. It is then necessary to study the machine in order to ascertain its adaptability to the existing conditions"--Introduction, page 1.
The Study Of Effect Of Definite Grain Sized Sand On The Shearing Strength Of Clays, Faruk Omer Akkoseoglu
The Study Of Effect Of Definite Grain Sized Sand On The Shearing Strength Of Clays, Faruk Omer Akkoseoglu
Masters Theses
"Slopes of all kinds, including mountains, hills, sea coast bluffs, river banks, and man made cuts and fills, stay in place only because of the shearing strength possessed by the soil or rock of which they are composed. The resistance of soils to shearing strength is probably the most important of all the soil properties to foundation engineers. Most of the serious structural failures which are due to unexpected soil behaviour are caused by deficiency in the shearing strength of the soil. Water, on the other hand, possesses no static strength in shear, therefore bodies of water have no surface …
Effects Of Sand Admixtures On The Physical Properties Of Soils, Necati Kanatsiz
Effects Of Sand Admixtures On The Physical Properties Of Soils, Necati Kanatsiz
Masters Theses
"The purpose of this study is to determine the effects of sand admixtures on the physical properties of soils. Soil may be defined as a heterogenous [sic] collection of rock and mineral fragments whose decomposition and disintegration have been brought about by the action of physical, chemical, and biological forces, working singly or in combination...In the conviction that the study of soils, with respect to highway engineering, is becoming more and more important this study was undertaken in order to learn whether the addition of sand would lead to desirable results, and if not, at least secure some further addition …
A Study Of Missouri Flint Clay, Edmond Preston Hyatt

"The problem is one of attempting to explain the peculiar nature of Missouri Flint Clay and to expand the knowledge concerning it. Among the questions for which answers are sought are: What makes Missouri Flint Clay so hard? What happens to Missouri Flint Clay when it is ground? What is the mineralogical constitution of Missouri Flint clay?"--Introduction, The Problem, page 1.
Investigation Of The Effect Of Absorption Tower Size Upon Overall Mass Transfer Coefficients, James Robert Murrell
Investigation Of The Effect Of Absorption Tower Size Upon Overall Mass Transfer Coefficients, James Robert Murrell
Masters Theses
"The purpose of this research project was to obtain data and determine whether or not a correlation exists between tower size and the overall mass transfer coefficient for a packed tower. A constant ratio of tower diameter to packing diameter of twelve to one was maintained. Three absorption towers were used; a twelve inch diameter iron tower, a six inch diameter iron tower, and a three inch diameter glass tower. One inch, one-half inch, and one-fourth inch Raschig rings were used in the corresponding towers as packing. The system used was the absorption of acetone by water from an acetone-air …
Temperature Fluctuations Within A Solid Of Finite Thickness, William Sanford Hogan
Temperature Fluctuations Within A Solid Of Finite Thickness, William Sanford Hogan
Masters Theses
"The object of this thesis is to determine by analytical methods the temperatures within a homogeneous plate of finite thickness subjected to a constant temperature on one side and a periodically fluctuating temperature on the opposite side. The heat flow in the other two directions is considered negligible in this problem. Periodic changes of temperature are frequent in nature and in engineering. The surface of the earth is heated periodically by the sun in its daily and annual cycle and the periodic temperature changes below the surface and the question to which depth these changes are appreciable were dealt with …
The Effect Of Calcium Chloride On Air-Entrained Concrete, Gerard Francis Hofstaedter
The Effect Of Calcium Chloride On Air-Entrained Concrete, Gerard Francis Hofstaedter
Masters Theses
"The essence of the problem is not fully set forth in the title in that all aspects are not covered. In this case, the term "effect" means how the compressive strength and the modulus of elasticity vary with the addition of calcium chloride...Many pages will be found concerning the relative merits of plain concrete versus air-entrained concrete. All phases of the problem have been covered thoroughly. Investigations have been conducted on both plain and air-entrained concrete to determine the compressive strength, flexural strength, durability and workability"--Introduction, page 1.
Separation Of Copper And Zinc On Synthetic Resins, Ernest Joseph Breton
Separation Of Copper And Zinc On Synthetic Resins, Ernest Joseph Breton
Masters Theses
"It was desired to know whether ion exchange resins could be of value to the metallurgist in the recovery and separation of metals. The recovery and separation of copper and zinc from dilute solutions on Amberlite IRC-50, a carboxylic resin, and Amberlite IR-120, a nuclear sulfonic resin, were investigated. It was found that Amberlite IRC-50 could effectively remove copper ions from a solution of copper and zinc. Amberlite IR-120, due to the strong sulfonic acid groups, exhibited only a slight preference for copper as compared to zinc. It would seem that a judicious choice of resins coupled with appropriate chemistry …
A Study Of Mine Scraper Efficiency On Materials Of Different Specific Gravities, Kermit Guy Rowley
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.
A Study Of The Efficiency Of Split-Second Delay Electric Blasting Caps In Underground Limestone Mining, John B. H. Fitzwilliam
A Study Of The Efficiency Of Split-Second Delay Electric Blasting Caps In Underground Limestone Mining, John B. H. Fitzwilliam
Masters Theses
"The introduction of electric blasting caps have delay intervals of the order of one-half to one second proved of advantage in many aspects of underground mining, particularly development work. Their use spread, until they now supersede fuse-and-cap firing wherever possible. Split-second delay electric blasting caps are a comparatively recent development from conventional delay caps. They have been found of practicable use in quarrying operations, and have been applied in many phases of underground mining. While evidence, to show that short-delay firing in quarrying is more efficient than instantaneous firing, is becoming increasingly conclusive, it remains to be proved that split-second …
The Freezing Temperatures Of The System Aniline-Ortho Toluidine, Ray W. Fahien
The Freezing Temperatures Of The System Aniline-Ortho Toluidine, Ray W. Fahien
Masters Theses
"The purpose of this investigation was to determine the freezing temperatures of the system aniline-ortho toluidine and to speculate on the theoretical significance of these results. The properties of this system are of considerable practical engineering interest since the system falls in a class of low-freezing organic mixtures which may have value as fuels for jet propulsion devices required to operate at extreme altitudes or in Arctic regions. Since nitric acid has been found to be a very effective and convenient oxidizer, the search for a suitable fuel to be used in combination led to aniline as having the most …
Effects Of A Reverse Order Of Firing Using Millisecond Delay Electric Blasting Caps In A Quarry Operation, Reginald John Jones
Effects Of A Reverse Order Of Firing Using Millisecond Delay Electric Blasting Caps In A Quarry Operation, Reginald John Jones
Masters Theses
"Evidence of the steady increase in the production of quarries is a reflection of the improved blasting practices that are being used. New explosives, the new millisecond electrical blasting caps and the endless experimentation carried on by both manufacturer and operator continue to aid or better the old methods of quarry blasting. In many instances the better results were obtained from practices hitherto unknown or at least unused. This report describes the results obtained from comparing quarry rounds shot in the accepted firing order and those shot in the reverse order of firing. The purpose of the report is to …
