The Design Of An Isolated Storage Battery Plant, Ottomar Henry Henschel, Joseph Anthony Walter Jan 1900

The Design Of An Isolated Storage Battery Plant, Ottomar Henry Henschel, Joseph Anthony Walter

Bachelors’ Theses

This thesis is respectfully submitted to the faculty of: the College of Applied Science and Engineering of Marquette University of Milwaukee Wisconsin by Ottomar Henry Henschel for the Degree of Bachelor of Science in Electrical Engineering, and Joseph Anthony Walter for the Degree of Bachelor of Science in Electrical Engineering.

Heating And Ventilation, Blydon Ellery Kenyon Jan 1899

Heating And Ventilation, Blydon Ellery Kenyon

Student and Lippitt Prize Essays

A survey of current practices in heating and ventilation systems is discussed with emphasis on the benefits of adequate heating and ventilation in all school buildings. Cited are air experiments at Davis Hall and the systems in Lippitt Hall (Rhode Island State College), the State Normal School in Providence and the Mayhew School in Boston. The essay argues that individual building and use dictate the most efficient system necessitating a working relationship between architects and heating engineers.


Influence Of Time And Temperature In The Roasting Of Sulphides, Roger Hanson Hatchett Jan 1899

Influence Of Time And Temperature In The Roasting Of Sulphides, Roger Hanson Hatchett

Bachelors Theses

"The original object of this work was to determine the relation between the quantities of oxide and sulphate formed in roasting a sulphide under known conditions of temperature, time and supply of air. But difficulties arose in constructing apparatus, which in the short time allotted could not be overcome. These are mentioned in description of apparatus, and were of such a nature that the relations between products and conditions are for the most part qualitative"--page 1.


Assay Of Copper Matte For Gold And Silver, Walter E. Soest Jan 1899

Assay Of Copper Matte For Gold And Silver, Walter E. Soest

Bachelors Theses

"Ores containing copper, and especially copper matte, have always been very annoying in assaying for the precious metals. In assaying copper matte, and ores containing much copper, by the usual method of scorification, the losses of silver an gold are considerable, owing to the fact that in order to obtain lead buttons, which are soft and free from copper, repeated scorifications are necessary, and moreover it is impossible to obtain lead buttons which are entirely free from copper"--page 1.


The Strength Of Cement Under Different Conditions, Francis Joseph Tayman Jan 1899

The Strength Of Cement Under Different Conditions, Francis Joseph Tayman

Bachelors Theses

"Derivation of some Empirical Formulae, showing relation between breaking strength, and various functions which enter into Cement testing. We find a great deal of experimental work done in Cement testing, also some curves plotted, but there are but few equations fitted to these curves, this, then, is the object of the present work. In this work a great many interesting points have been made manifest, most of them are of no practical value but merely of interest in themselves. The work has been on several of the most important ones, to be given subsequently. On these and a few others …

Pennsylvania Coal Fields, Arthur D. Terrell Jan 1899

Pennsylvania Coal Fields, Arthur D. Terrell

Bachelors Theses

Design Of A Mining Plant, George C. Clark Jan 1899

Design Of A Mining Plant, George C. Clark

Bachelors Theses

"It is to be hoped that in the perusal of this short discussion, the idea will not be lost sight of that the work has been done by a novice - probably a needless caution as the fact is patent at every step. Again, while the work is supposed to be laid along practical lines, no attempt has been made to abbreviate and show merely what is absolutely necessary. As the subject is treated as a thesis and not as a proposition to contractors, the attempt has been made to show the method of arriving at conclusions, and when necessary …

The Manufacture Of Portland Cement, Herman C. Cowen Jan 1898

The Manufacture Of Portland Cement, Herman C. Cowen

Professional Degree Theses

"The principal characteristics which, in the process of manufacture, sharply and clearly distinguish Portland cement from Limes, Hydraulic Limes, and other Hydraulic cements, are the necessity for carefully proportioning and finely grinding the raw materials to insure a homogenous [sic] mixture, and the extremely high temperature at which it must be burned in order to insure a sound a trustworthy product"--page 1.

The Electrolysis Of The Water Of A Copper Sulphate Solution, Ralph Barker Jan 1898

The Electrolysis Of The Water Of A Copper Sulphate Solution, Ralph Barker

Bachelors Theses

"The idea prevails generally, that when an electric current is passed through a copper sulphate solution, the water will be electrolysed sic when the difference of potential between the electrodes reaches about one and one-half volts. The object of the experiments detailed below was to determine whether or not the density of the solution has any effect on the electrolysis of the water, and if any such existed, to find out if there was any relation between them"--page 1.


Derivation Of Some Empirical Formulae, Showing Relation Between Breaking Strength And Various Functions Which Enter Into Cement Testing, Arthur D. Terrell Jan 1898

Derivation Of Some Empirical Formulae, Showing Relation Between Breaking Strength And Various Functions Which Enter Into Cement Testing, Arthur D. Terrell

Bachelors Theses

"Although we find a great many results of experimental work in cement testing, and some curves plotted, there seems to have been very little attempt made toward fitting equations to these curves. This then leaves an opening for original investigation. During my experiments quite a variety of interesting points have been made manifest. Most of them are of no practical benefit, but merely of interest in themselves. My work has been on a few of the most important ones, which will be given subsequently"--page 1.
