The Bloating Of Clays, Everett Walter Sharp Jan 1940

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 …


The Production Of High Alumina Refractories Bonded With Lumnite Refractory Cement, Joseph Lewis Hoffman Jan 1940

The Production Of High Alumina Refractories Bonded With Lumnite Refractory Cement, Joseph Lewis Hoffman

Bachelors Theses

"Users of refractories are constantly demanding a better product. There is a demand for a satisfactory neutral or basic refractory with a P.C.E. equivalent of cone 35 or better. A refractory with a very high alumina content would seem to solve this problem, however, the main difficulty has been to bond the unplastic alumina. From the literature it was learned that Lumnite cement has been satisfactory in the manufacture of a refractory concrete. Therefore this investigation was carried out to determine the adaptability of bonding corundum with Lumnite"--Introduction, page 1.


X-Ray Data Concerning Some Manganese-Copper Alloys, George Lester Mitsch Jan 1940

X-Ray Data Concerning Some Manganese-Copper Alloys, George Lester Mitsch

Bachelors Theses

"Until recently the only commercial method of producing metallic manganese in large ammounts sic was a pyrometallurgical process. Producing a metal of about 97% purity, it was not very satisfactory. With the advent of a process for producing a metal of 99.9 plus % purity electrolytically, introduced by the United States Bureau of Mines, for the first time was there a sufficient quantity of pure manganese available for alloy use. The manganese-copper system was chosen for study because of the inconsistencies in the reports of previous investigators, and because of the properties alloys of these components possess, such as magnetism, …


Red Glazes, Sidney Austin Peer Jan 1940

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.

I. IDENTIFICATION OF SPECIMENS. The method of designation used hitherto is not sufficiently differentiated to identify the present and future specimens since specimens with identical bottom flanges but different top flanges are used. For this reason from now on each specimen is designated by symbols and figures, for example D-18-16-88a in which: D designates a series of beams, 18 designates the gage of mterial used for web and bottom flange, 16 designates the gage of material used for the top flange, 8 designates the depth of the section in inches, 8 designates the width of the bottom flange in inches, …


The Effect Of Addition Agents In Grinding Portland Cement Clinker, Eugene Farrell Hill Jan 1940

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 Dec 1939

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" …

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering Sep 1939

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. OBJECT OF THIS REPORT The full program of tests outlined at the meeting of the Technical Subcommittee held in Ithaca on June 12 has been carried out with one exception: due to the limited time it has not been possible to determine the modulus of elasticity of the sheets. However since the modulus of elasticity of steel under any circumstances is about 29,000,000 to 30,000,000 p.s.i. this point of the program has no immediate practical significance. The following tests have been carried out: 1. Tests to failure of the remaining specimens of the series B - 22. 2. Determination …

I. OBJECT OF THIS REPORT Buckling tests have been carried out on the remaining three beams of the 22 gage series, i.e. B-22-812a, B-22-816a and B-22-820a. A stress survey has been made on the bottom flange of beam B-22-812b. A new series of 22 gage specimens has been designed for the further study of the bottom flange stresses and of the top flange buckling.

I. OBJECT OF THIS REPORT Since the investigations discussed in the previous report have proved that the stress distribution at midspan was fairly uniform in the narrowest, medium and widest beams of the 14 gage series, it seemed unnecessary to carry out investigations on the remaining two intermediate beams A-14-66 and A-l4-610. Three beams of the 22 gage series have been investigated so far, namely B-22-84a and b and B-22-88a. Detailed stress distribution surveys have been carried out at midspan on beams B-22-84b and B-22-88a. It was impossible to carry out such a survey on beam B-22-84a, since this beam …
