The Effect Of Glaze Fit Upon The Strength Of Missouri Zadock, Karl Emil Krill, Floyd Rolland Elliott Jan 1941

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 …


Dry Pressing Refractory Insulating Brick, Frank Clarence Steimke Jan 1941

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 Jan 1941

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 …


The Relative Merits Of The Electrolytic Deposit And The Galvanic Nickel Deposit When Used To Produce Enamel Adherence, Marvin Edward Pingel Jan 1941

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 Jan 1941

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 …


Solubility Of Glass Tank Refractories Using A Small Electrically Heated Furnace, James Vincent Heddell Jan 1941

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.
