Boiler Feed Water Purification At The Gorge Power Plant, Akron, Ohio, Bernerd William Adams Jan 1923

Boiler Feed Water Purification At The Gorge Power Plant, Akron, Ohio, Bernerd William Adams

Professional Degree Theses

"The conditions of operation at the Gorge Power Plant were such that raw water was used in all the boilers. The boilers were operated at an average of about one-hundred and seventy-five percent rating and considerable scale formed in the tubes of the boilers. It was evident that this caused a large loss in fuel and increased the expense of maintenance. It was necessary to employ a number of men to remove the scale. An investigation was made to determine as nearly as possible the loss caused by the use of impure water. After the investigation, an attempt was made …

The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge Jan 1922

The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge

Masters Theses

"One of the most serious difficulties confronting anyone working on stratigraphic problems in the Ozark area is the lack of detailed faunal lists of the various formations. A great deal of general work has been done, but very few detailed faunal studies have ever been published, and correlation of the Missouri section with sections in adjoining states is often difficult.

In a recent paper, Dake has discussed the origin and correlation of the St. Peter sandstone. In this study he found considerable difficulty in correlating the various formations above the St. Peter, and at his suggestion, the present study was …


The Action Of Tan Bark In The Manufacture Of White Lead By The Old Dutch Process, Elmer List Jan 1922

The Action Of Tan Bark In The Manufacture Of White Lead By The Old Dutch Process, Elmer List

Masters Theses

"This investigation was undertaken because there is very little definite information in print, regarding the micro-organisms which play such an important part in the Old Dutch Process for manufacturing white lead. The statements concerning this process are very general in character. For instance, one book states, "The first action which goes on is to convert blue lead into basic acetate of lead. This is brought about by the heat of the fermenting tan, causing the evolution of acetic acid from the liquid of the pots." Albert H. Hooker in a little treatise on white lead says: "As it stands now, …


Investigations In Colloidal Phenol, Charles James Millar Jan 1922

Investigations In Colloidal Phenol, Charles James Millar

Masters Theses

"In making some experiments with various colloids it was noticed that phenol and water seemingly formed a colloid, so it was deemed advisable to experiment farther and see if this fact could be established. The references on this subject vary widely and for this reason some of them are given here. Ostwald recognised [sic] the colloid state of a phenol-water mixture at the critical temperature but evidently failed to see the possibility of the phenol-water colloid at all temperatures. In the following article I will try to show that the phenol-water mixture forms a colloid, not only at the critical …


The Equilibrium Of The Reaction Zn + Co₂ = Zno + Co, Clarence Ware Burkhart Jan 1922

The Equilibrium Of The Reaction Zn + Co₂ = Zno + Co, Clarence Ware Burkhart

Masters Theses

"Many attempts have been made in the last twenty years to smelt zinc ores in the electric furnace. The disadvantages of the present retort process have been discussed so often that they need not be dwelt upon here. The principle ones are, the low thermal efficiency of the retort furnace, low metal recoveries, small smelting units necessary, short life of the retorts and the difficulty of treating impure and low grade ores. Electric smelting offers remedies for most of these difficulties"--Introduction, page 1.

The Effect Of Sulphur Dioxide Gas On Sweet Potatoes, Cotton, And Sorghum Cane Plants, Milburn Leo Dorris Jan 1922

The Effect Of Sulphur Dioxide Gas On Sweet Potatoes, Cotton, And Sorghum Cane Plants, Milburn Leo Dorris

Bachelors Theses

"The chief allegation made by many of the complainants sic in the vicinity of the zinc smelters is that the emanations from the stacks are detrimental to the yield of the crops, especially Sweet Potatoes and Cotton. They claim that on account of the leaves being burned or bleached, the entire plant is poisoned and weakened and the yield is thereby reduced. It was even claimed by some that the presence of the smoke in the atmosphere around the plant has a weakening effect in that it is cumulative, and, while it does not always visibly show, yet the general …
