The Chemical Engineering Aspects Of The Saint Louis Smoke Problem, George Augustus Hale

Professional Degree Theses

"During past years smokeless combustion of fuels has been conscientiously sought only in those larger industrial plants where fuel costs were a major factor. Smoke was considered a sign of prosperity in some moderate and even large size industrial practice, and no wholehearted effort was made to utilize the vast amount of energy lost through the smoke stack in the form of unoxidized carbon.

Inefficient combustion, which is so common today, is due in part to a wrong approach to the study of this problem. Industrial combustion, as a science, has, to a certain extent, been left to the mechanical …

Some Causes For Porosity And Leakage In Non-Ferrous Castings, Alfred H. Hesse

Professional Degree Theses

"Non-ferrous copper base alloys find many applications in industry. Among these alloys one finds the tin bronzes rather widely used for many purposes, and by delving still farther one finds pressure castings as one of their important applications. In many foundries the percentage of rejections due to leakage or porosity is quite high. This is obviously very costly since leakage is generally only found after machining. It is with a view to determine the causes for leakage in pressure castings and to devise methods for its prevention that the work described in this thesis was undertaken. It is not intended …

The Scope Of Functions Delegated To The Engineering Department Of A Typical, Progressive Metal Mine, Alvin William Knoerr

Professional Degree Theses

"Nearly every conscientious engineering student will subject his college courses to an occasional critical analysis in an effort to assure himself that the studies he is pursuing will be a valuable aid to him in future practice. Possibly this skeptical attitude is accentuated by published letters of graduate mining engineers who decry the courses of mining schools in general and clamor for more practicability and higher specialization. Pure science as it is taught may at times seem to be very remote from any possible practical application. Mathematics may appear to be highly abstract. It seems quite logical that the degree …

Dewatering & Rehabilitating The Oronogo-Webb City Mining Area, Robert Knox Stroup

Professional Degree Theses

"The object of this paper is to describe the dewatering of the Oronogo-Webb City mining area, and the subsequent mining operations which were carried on in the northern section of that area. It deals with the development in that district during the time the writer was familiar with operations there; i.e., from 1935 to 1939, inclusive, and no attempt is made to describe the open pit mining and local milling which have been carried out as a latter part of this same project. Also, no attempt is made to describe the surface drainage work which was planned and carried out …

The Effect Of Glaze Fit Upon The Strength Of Missouri Zadock, Karl Emil Krill, Floyd Rolland Elliott

Bachelors Theses

"We know that, in the case of a beam, the really effective part of the cross-sectional area is that part farthest from the neutral axis. The I-beam, with most of the central area eliminated, is just as strong as is the rectangular beam of similar outside dimensions. Why should not the glaze on a piece of ceramic ware play as important a part in the strength of the piece as does the outermost area in a beam? Microscopic cracks in the flanges of an I-beam weaken it appreciably. Might not a parallel case exist in a piece of glazed pottery …

The Relative Merits Of The Electrolytic Deposit And The Galvanic Nickel Deposit When Used To Produce Enamel Adherence, Marvin Edward Pingel

Bachelors Theses

"The purpose of this paper is to determin sic if nickel deposited electrolytically from a nickel bath at 100ʻF. or less gives the same adherence qualities to enameling steel that nickel deposited galvanically at 160-180ʻF. produces"--Purpose of This Paper, page 1.

Characteristics Of Pyrometric Cone Equivalent Test Furnaces, Alfred W. Allen, Joseph T. Dusza

Bachelors Theses

"Though the method of determining the pyrometric cone equivalent of various silicate materials used in the refractories industry has been standardized by the American Society for Testing Materials (A.S.T.M. Designation: C24-35) as to the rate of heating, method of preparation of sample, mounting of test cones, and the interpretation of results, there still remains some variation in the results obtained by different operators using different types of P.C.E. furnaces. The three types of furnaces most generally used are: the Fulton-Coursen Granular Resistance Furnace, the Denver Fireclay Furnace developed by the American Refractories Institute using gas, and the General Refractories' Oxy-acetylene …

Dry Pressing Refractory Insulating Brick, Frank Clarence Steimke

Bachelors Theses

"The expensive process of grinding the insulating brick and the slow production methods of hand forming led to the possibilities of dry pressing the brick. The use of the dry press would increase production, give greater uniformity to the brick and materially reduce grinding if not eliminating it entirely. Since present day combustives were either impractical or else impossible to use, some new material must be found. Three materials presented themselves, napthalene, sulfur, and petroleum coke. The former for its low melting temperature and the latter two for their complete volatility at high temperatures and low if not negligible resiliency. …

Firing Behavior Of Missouri Plastic Fire Clay, William E. Crockett

Bachelors Theses

"There are two districts in Missouri in which plastic fire clay occurs. The oldest and least significant of these deposits is the "Cheltenham", in the St. Louis area. The most prominent area in which plastic fire clay occurs is generally termed the "east central" district. Included in this district are Calloway, Montgomery, Audrain, Warren, Boone, Monroe, Pike and Lincoln Counties. The clay as tested in this report occurs in Boone County, near Columbia. A plastic fire clay does not have as high a P.C.E. (pyrometric cone equivalent) as the ordinary flint and semi-flint clays, but its high plasticity warrants its …

Solubility Of Glass Tank Refractories Using A Small Electrically Heated Furnace, James Vincent Heddell

Bachelors Theses

"This investigation was undertaken to study the refractory blocks used in glass furnaces - their relation with the molten glass. It was decided to employ for this examination a model glass tank, heated by electrical carborundum resistors known as Globars. Experimental glass tanks have been constructed using fuel oil or gas to obtain the required heat to perform melting. These fuels were used mainly to simulate commercial practice and thus to obtain results which could be easily applied to industrial furnaces. The design of a model electric tank is included as part of this investigation"--Purpose of the Investigation, page 4-5.

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

I. SCOPE OF THIS REPORT In the preceding 14th Progress Report a method was proposed to determine the forces acting in the welds in the web of I-beams composed of two channels. This method essentially has been based on the magnitude "e", the distance of the flexural center from the axis of the web. A formula for "e" was given which applies to symmetrical channels of uniform thickness. In the present report this expression for "e" will be simplified and a more general expression will be derived for "e" for symmetrical channels with web thickness differing from flange thickness. Furthermore, …

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

I SCOPE OF THIS REPORT It has been mentioned repeatedly in previous Reports that the spot welds in the web joining the two parts of the beam tended to pull apart at the supports. It is therefore obvious that, in order to properly design such beams, this fact must be taken into consideration. The present report undertakes to give an analysis of this behavior and to stipulate certain requirements with respect to these welds (strength, spacing) which have to be met in order that such failures may be excluded. The present analysis pertains only to beams made up of two …

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to investigate the age-hardening of aluminum with magnesium and zinc in such proportions as to conform to the compound MgZn₂.

Because of a lack of time and proper equipment, the only property investigated was the hardness as indicated by the Rockwell Superficial Hardness Tester.

The Investigation Of Different Variables In The Assaying Of Silver Cyanide Solution, Warren M. Mahan

Bachelors Theses and Reports, 1928 - 1970

The assaying of gold and silver cyanide solutions is by no means new. The first method of analysis which is given in the literature is an evaporation method by S. B. Christy in 1896. However, the fire assaying of gold and silver dates further back than this. There is a method of fire assaying for gold and silver given in literature as early as 1556 in Georgius, Agricola’s De Re Metallica book.

The Measurement Of Current Efficiency In Zinc Sulphate Electrolytes Containing Antimony And Cobalt By Hydrogen Evolution, Arthur R. Hard

Bachelors Theses and Reports, 1928 - 1970

The measurement of current efficiency by hydrogen evolution is based on the assumption that the portion of the current which deposits no zinc will release hydrogen. This assumption is correct for solutions containing no impurities electropositive to zinc.
