A Study Of Anode Corrosion And Its Influence On Cathode Purity In Electrolytic Zinc Production, Harold John Roesser

Masters Theses

"Anode corrosion is a problem with which electrolytic zinc producers have been concerned from the beginning of the practice. It has been attacked here from the view of modern practice, using alloyed anodes"--Introduction, page 1.

Pressure Transmission In Clays Affected By Time Of Pressure Application, Robert Edward Lee

Bachelors Theses

"Experienced dry-press operators have long known that when they slow down their presses, to the proper speed they are able to exert more pressure on a wetter mix with out pressure cracks becoming apparent. When a clay mix is compressed in a dry-press there is a gradation of the pressure exerted, from the rams to the center, causing in some cases a soft centered brick. "Shelly brick", are undersirable sic because they do not have uniform physical properties through out. This weakens their structure, due to unequal stresses developed in drying and fireing sic. The defective structure of dry-pressed brick …

Size And Shape Of Clay Grains As Affected By Various Methods Of Grinding, Henry William Meyer

Bachelors Theses

"It is a common belief among those persons manufacturing dry pressed brick that the shape of grain of the clay used for this purpose would materially affect the physical properties of the resultant product. Some believe that clays, dry pan-ground, give a better product than clays disintegrated mechanically or passed through rolls. In some recent dry press investigations it was found that some milling methods gave an advantage over other methods, in the matter of pressure transmission. Due to this, a possible cause for the advantage was attributed to the shape of the grains resulting from the various methods of …

The Commercial Value Of High Iron And High Alkalie Diaspore, William Lucius Mccracken

Bachelors Theses

"In a recent survey of the refractory field particularly regarding high iron and high alkali diaspore it was suggested that perhaps some of these impure clays had the proper flux content to make them a body of stable volume in the initial firing operation. At present there is an apparant sic lack of information regarding the commercial value of these impure diaspores. One of the great problems in the use of diaspore refractories is the lack of stability of volume while in service subjected to severe heat treatments of varying degrees"--page 3.

The Effect Of Bentonite On The Transmission Of Pressure In Green Dry Press Blocks, Charles William Mccaw

Bachelors Theses

"The object in view in this work was to study the effect of the addition of bentonite on the pressure transmission of dry pressed ware, consisting of plastic fire clay. It was hoped that the bentonite would improve the transmission of the pressure to a noteable extent, forming a stronger, more evenly pressed block than has before been accounted for. This would facilitate the dry pressing of block that tended to crumble and disrupt from excessive pressure, allowing the ware to be pressed harder, and therefore making a more dense product"--Reasons For Investigation, page 4-5.

The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Variation In Grog Size, Henry Rickel Herron

Bachelors Theses

"In the formation of dry pressed ware, the transmission of pressure is of vital importance to the quality and character of the finished product as regards the resistance to spalling, load at high temperatures, slag action, abrasion and other physical properties. Furthermore, the transmission of pressure is a limiting factor as regards the size and irregularity of shape of a product manufactured by the dry press process"--Introduction, page 1.

The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Variation In Grog Size, Stanley John Tompach

Bachelors Theses

"In the formation of dry pressed ware, the transmission of pressure is of vital importance to the quality and character of the finished product as regards the resistance to spalling, load at high temperatures, slag action, abrasion and other physical properties. Furthermore, the transmission of pressure is a limiting factor as regards the size and irregularity of shape of a product manufactured by the dry press process. Prior to the time of this investigation several companies have succeeded in producing ware up to six (6) inches in depth; but an increase over six inches has resulted, in every case, in …

The Effect Of Small Amounts Of Chrome Ore On Dry Press Diaspore Refractories, Allen John Reid

Bachelors Theses

"The term "Diaspore" as used in this paper will be used to mean the diaspore clay from which refractory bodies are made. The pure mineral Diaspore (Al₂O₃ . H₂O) has an Al₂O₃ content of 85%, while the best grades of diaspore clay run from 76% to 79% diaspore. Diaspore clay consists of a varying percentage of diaspore, ranging from 60% to 79%, and the remaining percentage as clay. The most objectionable impurities which occure sic in diaspore clay are alkalies. The chief source of diaspore is the central part of Missouri. It occurs in pot hole formations accompanied by "flint" …

Chemical Control -- Influence On Manufacture And Quality Of Cement, Joseph Owen Hunt

Professional Degree Theses

"Definition:- Portland cement may be defined as the product obtained by finely pulverizing clinker produced by calcining to incipient fusion an intimate and properly proportioned mixture of argillaceous and calcareous materials with no additions subsequent to calcination excepting water and calcined or uncalcined gypsum. While a review of Portland cement analysis would show a wide variation in chemical composition, it must not be supposed that such latitude in proportioning the raw material really exists. If the resulting Portland cement is to be sound, normal setting, and of good strength it is imperative that the raw materials shall be correctly proportioned …

Japan, Van Hoose Smith

Professional Degree Theses

"This ore is mined from a quartz vein which is refined by small seams of graphitic clay material, and the walls of the vein consist of a sort of graphitic shaley material. The above graphitic materials break down under treatment into a rather peculiar clay which was called primary colloidal slime. The milling process in use consists of stamp milling followed by the separation into sand and primary slime in Dorr Duplex Classifiers. The primary slime overflow from these classifiers, which is all practically thru 220 mesh, is thickened and treated by flotation. Normally and with a good supply of …

Newspaper Propaganda During Time Of War, Evelyn L. Senn

Bachelors’ Theses

Twelve years have elapsed since the World Powers engaged in a great conflict. Nationality and sanity have taken the place of war frenzy. Bias, hate, and prejudice should have lost their sting. A paper on the newspaper's part in war propaganda would be difficult to write during a war or just after one, because it would be difficult to treat sanely; now, however, the vast world public can see impartially how efforts were made to forge public opinion.

A Study Of The Miscibility Of Various Liquids With Ethylene Glycol, Joseph J. Furlong

Bachelors’ Theses

Ethylene glycol is a compound possessing great interest, both from a theoretical and a practical standpoint. In its properties it lies midway between ethyl alcohol, C₂H₅0H, and glycerol, C₃H₅(0H)₃, the three compounds together forming an homologous series of alcohols.

A few years ago this substance was a scientific curiosity, produced solely by laboratory methods, and without any commercial value, although it had been known for more than sixty years. Today the manufacturers cannot produce enough glycol to satisfy the growing demand. The DuPont organization wanted to use it in a …

The Construction And Evaluation Of A Study Technique For American History, Jennie Penn

Electronic Theses & Dissertations

This study attempts two things: (1) To build a usable and practical technique for teaching high school pupils to more effectively study American history; and (2) To determine the value of this new technique by using it in a typical high school history class.

The study technique was based upon the results of a questionnaire given to one hundred eleven high school pupils studying American history in the Pittsburg, Kansas, high school and the Coffeyville, Kansas, high school. The pupils filling out the questionnaire were asked to check the habits and methods of study they used in studying American history. …
