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 …

The Reactions Of Acid Halides With Sodium, Magnesium, Zinc And Amalgams, William H. Webb Jan 1939

The Reactions Of Acid Halides With Sodium, Magnesium, Zinc And Amalgams, William H. Webb

Masters Theses

"The reactions of acid halides with metals are of interest because there seems to be a possibility of abstracting the halogens from two molecules of the halide, and thereby bringing about a coupling reaction; or the formation of an intermediate organo-metallic compound which would react with another molecule of the acid halide. The result of these reactions should be the formation of diacetyl and acetyl chloride and of dibenzoyl or benzil from benzoyl chloride. This procedure would be far better than the usual procedures for the preparation of these compounds...The results reported in the literature by different workers, on the …


Design Study Of A Three Span Continuous Tied-Arch Bridge, George Perry Steen Jan 1939

Design Study Of A Three Span Continuous Tied-Arch Bridge, George Perry Steen

Masters Theses

"In this study of the continuous tied-arch bridge, having one main span and two equal side-spans, the following items are endeavored: (1) To set up the total internal work equations and to find the values of the unknown forces or redundants. (2) To compute to maximum moments for design and to complete the design of the super-structure for one bridge. Details, such as the gusset plates, rivets, connection angles, etc., are not designed; the effect of such being allowed in the design for dead load as a certain per cent for details. (3) To set up hypothetical conditions for other …


A Process For Making Refractory Insulating Brick, Albert Lloyd Tetley Jan 1939

A Process For Making Refractory Insulating Brick, Albert Lloyd Tetley

Bachelors Theses

"The object of this study was to investigate the fundamental principles of producing an insulating brick by making the pore structure of air bubbles entrapped in a clay slip. Since a clay water mixture or any material containing entrapped air will loose this air when placed under vacuum, it is thought that placing the clay slips under a pressure would cause a considerable pore structure in the slip when the pressure is released. In the common method of making insulting brick, the fired brick must be ground to size as they cannot be molded to a definite size and shape. …


Organization Of Geophysical Parties For Foreign Exploration, Charles Howard Dresbach Jan 1939

Organization Of Geophysical Parties For Foreign Exploration, Charles Howard Dresbach

Professional Degree Theses

"Special conditions encountered in much foreign work make it necessary to consider many factors which are not encountered in domestic programs of geophysical exploration for oil. Although extremely difficult working conditions are frequently met in domestic operations by company and contract crews, the large store of past experience, the availability of fresh supplies, replacement or new equipment, and the proximity of the helpful home office make their surmountal more or less a matter of routine. Contrariwise, foreign operations are frequently conducted under much more difficult conditions, supplies and equipment can be secured only after long and costly delays, and the …

Some Effects Of Geology On The Relation Between Rainfall And Run-Off, James Smythe Reger Jan 1939

Some Effects Of Geology On The Relation Between Rainfall And Run-Off, James Smythe Reger

Professional Degree Theses

"For the past five years, the writer has been engaged either directly or indirectly in the investigation of water supplies. Studies and observations made in Texas, Oklahoma, Colorado, and New Mexico, have brought to his attention the importance of geology to hydrology. This is especially true in reference to the relation between rainfall and run-off. In all texts and other publications relating to hydrology, the importance of geology to the subject is hardly more than mentioned. In the absence of actual stream flow records, many engineers resort to either the "direct comparative method", or the "rainfall percentage method", in estimating …


The University Of Missouri, A Centennial History 1839-1939, Jonas Viles Jan 1939

The University Of Missouri, A Centennial History 1839-1939, Jonas Viles

History of the University

The School of Mines and Metallurgy of the University of Missouri is unique among the various functional divisions of the parent institution at Columbia. Although governed by the same board of curators as manages the affairs of the University as a whole, it occupies a separate campus in another section of the state. The location of the school at Rolla, in Phelps county, has not, of course, in itself, given any particular or specific direction to the development of the institution; but it has made the story of the growth of the school necessarily a different one from what it …
