Joint Planes In The Rhyolites Of The Butte District, Montana, John B. Hopkins

Bachelors Theses and Reports, 1928 - 1970

The problem herein discussed deals with the pointing planes found in the area of rhyolite located in the northwestern portion of the Butte District. The question to be determined was whether or not the pointing planes in the rhyolites could be class­ified with the Butte Ore fissure systems.

A Bentonite Deposit Near Warm Springs, Montana, R. H. Larson

Bachelors Theses and Reports, 1928 - 1970

This report deals with a bentonite deposit recently developed, approximately seven miles northeast of Warm Springs, Montana. A group of claims have been staked on the deposit and are owned by the Lincoln Mining Company of Anaconda, Montana. The company also has several claims prospected for silver one mile from its present site of operations, but the silver prospects have failed to produce. The bentonite deposit was discovered incidentally during the course of other development work, and at present two adits have been driven into the side of a mountain, each crosscutting a vein-like mass of bentonite varying from two …

The Effect Of Hydrogen Overvoltage On The Electrolytic Deposition Of Zinc, John M. Munzenrider, Kenneth O. Sweeney

Bachelors Theses and Reports, 1928 - 1970

In the deposition of metallic zinc by electro­lysis from neutral or acid solution, little difficulty is experienced provided certain impurities are absent from the electrolyte. The use of the process has long been considered as a potential source, patents on the process having been issued as early as 1880. However, the early experimenters failed to realize the importance of impurities in the electrolyte, and for this reason, the process suffered several severe setbacks when commercial plants were built.

The Electrolytic Deposition Of Chromium Upon Aluminum, E. Fults, L. D. Voerge

Bachelors Theses and Reports, 1928 - 1970

The purpose or this investigation is primarily to determine the best conditions for plating chromium on aluminum. The work was carried out with the hope of obtaining coherent deposits, and of determin­ing the conditions under which such deposits may be duplicated.

Preliminary Construction Of A Photo-Electric Cell Concentrator, Stanley S. Williams

Bachelors Theses and Reports, 1928 - 1970

The separation of the valuable portion from the waste portion of an ore is an individual problem for every ore. However, the various methods for accomplishing this end, more or less classify themselves by the physical properties of the constituents of the ore. Most of the properties of minerals have been utilized in some way or other to affect the separation of the valuable from the invaluable parts. Practically nothing has been done so far with color and luster to attain this purpose.

It is believed that the photo—electric cell could also be used in concentrating a certain class of …

A Preliminary Study Of The Separation Of The Copper Sulfides From Sphalerite And The Effect Of Certain Reagents On Some Of The Pure Copper Minerals In Synthetic Mixtures, Gailen T. Vandel

Bachelors Theses and Reports, 1928 - 1970

The problem of separating the copper sulfide minerals from sphalerite, in copper - zinc ores, has been a difficult one. This is largely due to the lack of adequate research and the small amount of data obtainable on the behavior of copper and zinc sulfide minerals in flotation circuits.

A Study To Determine The Feasibility Of Irrigating The Lands Included In The Cache Valley Water Conservation District No. 1, I. Donald Jerman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this report is to investigate the feasibility of irrigating the lands of the Cache Valley Water Conservation District No. 1. The district, as it now stands, is very much in need of many improvements. The Main canals are now in use and are in a good condition to serve all the lands with the required amount of water, but the few laterals that are now constructed, are in a poor condition, with the remaining laterals yet to be finished.

Before successful irrigation can be practiced, a large portion of the land will require leveling and small areas …

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.
