Depreciation, Reginald Henry Brinton Butler Jan 1912

Depreciation, Reginald Henry Brinton Butler

Professional Degree Theses

"In estimating and stating working costs, we are often brought face to face with an important item of expense, for which no receipt is ever given and no invoice is ever rendered, viz: DEPRECIATION. For this reason perhaps the different ways of charging this liability are innumerable. No two people often have their minds cast into similar moulds and in the charging of this item, the human and personal factor enters very largely into consideration. People differ widely as to just what part of the capital must be laid aside to meet "changing conditions in trade" and what ought to …


The Measurement Of Compressed Air And Its Consumption In Rock Drills, Homer Kent Sherry, William Porri Jan 1912

The Measurement Of Compressed Air And Its Consumption In Rock Drills, Homer Kent Sherry, William Porri

Bachelors Theses

"The object of this thesis is to investigate the measurement of compressed air and to determine its consumption in rock drills. Our intention at first was to run more exhaustive tests on the drills, but due to the large amount of work necessary in rigging up the apparatus and computing results, we found it necessary to curtail our work to representative types of the hammer and the piston machines. We regret being unable to give more complete data in regard to the drills, but hope to point out fields for future work since, with the increased facilities now at hand, …

I refer the reader to the curves to see what really happened"--page i.


Efficiency Of The Missouri School Of Mines Power Plant And Cost Of Operation, Cairy C. Conover, John Richardson Kenney, Louie Lincoln Coover Jan 1912

Efficiency Of The Missouri School Of Mines Power Plant And Cost Of Operation, Cairy C. Conover, John Richardson Kenney, Louie Lincoln Coover

Bachelors Theses

"These tests were made for the purpose of getting the efficiency of the electric power plant as it was being run and the cost of operating it. Tests were first made on the boilers separately. The load at the time of the test was too heavy for one boiler and too light for tow, part of the steam being used for heating the buildings and for the air-compressor. This made it so that no combined test of the boilers and generating couple could be made until the warm weather came and the laboratories using compressed air were closed, which was …

A Process For The Separation Of Barite And Sphalerite, Cairy C. Conover, Edwin Robinson Morris Jan 1912

A Process For The Separation Of Barite And Sphalerite, Cairy C. Conover, Edwin Robinson Morris

Bachelors Theses

"The present price of zinc has stimulated a greater interest in Sphalerite Barite separations than has been manifested for some time. A great many processes have been worked on and have failed for many reasons, the main one being that the physical characteristics of the ore varied so much. The process that is successful must be independent of these variations. The following process is one that depends on a chemical phenomenon and is adapted to any sphalerite-barite separation. This series of experiments was performed by the authors at the Missouri School of Mines and Metallurgy, Rolla, Mo. and was embodied …

Roasting Pyrite For Magnetism With Minimum Sulphur Volatilization, Dale Irwin Hayes, Clark Watson Wright Jan 1912

Roasting Pyrite For Magnetism With Minimum Sulphur Volatilization, Dale Irwin Hayes, Clark Watson Wright

Bachelors Theses

"In Wisconsin and other zinc mining districts the blende is frequently found associated with pyrite and marcasite. In the Wisconsin district, especially, the marcasite content of the mine-run ore is high being frequently equal to and in many cases greater than the sphalerite content. At time the marcasite and sphalerite together constitute as much as 25 or 30% of the min-run ore. The characteristic milling treatment of this ore is; first, hand-picking, and then over grizzlies, tromells, rougher and cleaner jigs. Owing to the fact that marcasite and sphalerite differ but slightly in specific gravity the jig concentrate obtained is …
