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 …


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 …


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.


Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering Jan 1941

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 …
