It is situated about five miles from Neihart, Montana. A three-and-one-half-mile trucking road connects the mine with a railway siding. The property is in the Little Belt Mountains, at an elevation of about seven thousand feet. The climate is severe, the winters long, and …

Commercial Mineral Waters Of North-Central Texas, Shirley Alfred Lynch

Professional Degree Theses

"The great increase in demand for mineral water the past few years has lead to the development of a new industry, the making of mineral water crystals. Wells that were abandoned as unsuitable for water supply, due to their salinity, have been cleaned or redrilled, in a frantic effort to supply the ever increasing demand of the crystal plants. The inevitable result is that their waters are being used at an alarming rate of consumption. The popular conception is that there is no end to the amount of charged waters that may be obtained, and, as a result, within some …

Dedusting And Preparation Of Screenings, Erwin Gammeter

Professional Degree Theses

"There are a number of advantages to be obtained by the removal of fine dust and the proper proportioning and mixing of the smaller grades of coal. The dedusted coal is much better for mechanical stokers since it contains very little dust to drop through the grates or to be carried up the stack. The fuel bed is more open with the dust removed, combustion is better, and the draft is more easily regulated. Dust removal also increases the fusion temperature of the ash, reducing the amount of slag formed on the grate. Elimination of clouds of dust at points …

Personnel Relations, James Kneeland Richardson

Professional Degree Theses

"The author has not attempted to portray an idealistic scheme in this paper. It is the result of personal experience among working men, listening to their complaints and grievances; and suddenly discovering that all any man asked was the right to be independent during his declining years; the right of free speech; the right to earn his living by working under good conditions; and the right to receive in compensation for his labor a fair and equitable division of profits on goods resulting from his work. All the points taken up in this paper are not common to one industry, …

Tax Depletion Problems Of The Tri-State District, Glenn A. Dooley

Professional Degree Theses

"The passage of the Internal Revenue Act of 1918, with its articles affecting mines and mining, ushered in a new field of activity for the mining engineer. With the final adoption of the Act in February 1919, it became evident that an immediate valuation would be required; not as of the present date but, in the case of older mines, as of a date six years before. This retroactive legislation brought confusion to the operator and taxed the ingenuity of the engineer. The law provided that the value of the property could be subtracted from the income tax returns, as …

Sherardizing As Applied To Stampings From Light Gauge Metals, Matthew Patrick Brazill

Professional Degree Theses

"Sherardizing, or dry galvanizing as it is sometimes called, is a process whereby articles of iron or steel are rendered rust proof by applying a coating of zinc. The coating produced by this process is first an alloy with the underlying metal. After this alloying action is completed the outer layer of zinc is deposited. Briefly stated, this coating is not a pure layer of zinc, but a zinc iron alloy"--The History of Galvanizing, page 1.

It will be our aim here to show how the internal combustion engines operates and discuss some of the types in use in automobiles and stationary power plants. When one contemplates the immense amount of power developed …

An Investigation Of The Mechanics Of Oil Migration From The Source Beds To The Reservoir Beds, William Reed Quilliam

Professional Degree Theses

"The study of the migration and accumulation of petroleum has very naturally been analytic, with the result that we have had a variety of studies of its several features. the generation of petroleum, its migration and its accumulation in reservoir rocks is not a rapid process which may be accomplished and terminated in a comparatively short time, but one of long and almost continuous operation from the time of its inception. In this study the author is not attempting to formulate a new theory for the movement of oil from its point of origin to its final point of accumulation …

The Manufacture Of Liquid Oxygen And Its Use As An Explosive, Francis Kinlock Middleton Hunter

Professional Degree Theses

"Oxygen was first liquefied in 1877, but the first record of its use commercially as an explosive was in 1899 when part of the famous Simplon tunnel between Italy and Switzerland was driven with this explosive. Owing to the difficulties of storing and using this liquid, little more progress was made until the Great War, when Germany, forced to experiment with any promising explosive because of her rapidly diminishing stocks of Chilean nitrates, made considerable headway in the technique of using liquid oxygen...Since the War liquid oxygen explosives have been used extensively in France and Germany and to a lesser …
