Gas Analysis By Absorption, Albert D. Mcmahon
Gas Analysis By Absorption, Albert D. Mcmahon
Bachelors Theses and Reports, 1928 - 1970
There is practically only one method of gas analysis. This was worked out many years ago by Bunsen, Hempel, and Winkler and consists in the successive absorption with different chemicals of the various constituents of the gas. The only improvement to this method is the oxidation and combustion of different components of a mixture followed by absorption.
Oil And Gas Production Methods In Montana, Edgar A. Scholz
Oil And Gas Production Methods In Montana, Edgar A. Scholz
Bachelors Theses and Reports, 1928 - 1970
Montana's oil and gas industries aggregate a gross income of over 12,000,000 annually to the state. Oil and gas fields have been thoroughly discussed in literature as to geology, location, production and future possibilities. The specific object of this report has been to compile a comprehensive study of the production methods as they occur.
A Rapid Determination Of Small Amounts Of Lead In Zinc, George T. Hanson
A Rapid Determination Of Small Amounts Of Lead In Zinc, George T. Hanson
Bachelors Theses and Reports, 1928 - 1970
This investigation, carried on in the metallurgical laboratories at the Montana School of Mines, was undertaken with the desire to work out a rapid method for the estimation, or the determination, of the amount of lead in zinc.
Alloys Of Lead And Tellurium, Ettore A. Peretti
Alloys Of Lead And Tellurium, Ettore A. Peretti
Bachelors Theses and Reports, 1928 - 1970
Prior to the last few years little practical use was made of the element tellurium, which is obtained from gold and silver tellurides and from the slimes of electrolytic copper refineries. Lately, however, more study has been made of its properties when alloyed with other metals. It was the purpose of this thesis to study the effects of the addition of tellurium to lead, particularly in small amounts.
The Electrical Resistance Of Metals In Their Hard And Soft States, Eugene A. Avery
The Electrical Resistance Of Metals In Their Hard And Soft States, Eugene A. Avery
Bachelors Theses and Reports, 1928 - 1970
Many investigations have shown that the electrical resistance of soft annealed metals is usually smaller than that of metals in their hard, cold worked state. By annealing cold-worked metals, the electrical resistance decreases to a minimum and then increases upon continued annealing at higher temperatures. The work performed in this investigation upon silver, aluminum, copper, nickel, and soft steel corroborates this idea.
