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 …

A Study Of Missouri Springs, Harry Cloyd Bolon

Professional Degree Theses

The particular phase of the above problem of which …

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 …

The U.S.G.S. Topographic Map: Its Value And Method Of Construction, Daniel Kennedy

Professional Degree Theses

"Topographic maps, which differ from the base map in that they show not only relative distance and direction but also the accurate shape of the earths surface, are not new, but represent the constant improvement in mans efforts to reproduce on paper all that he sees and knows of regions of the globe.

While history records the first maps known to man as being made by the Babylonians on clay tablets centuries before Christ, the first relief map was made by the Ninth Inca who died in the year 1191. The present method of showing relief by contours was employed …

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.

The Use Of Activated Alumina For Reclaiming And Reconditioning Turbine, Transformer And Circuit Breaker Oils, Thomas Odie English

Professional Degree Theses

"Advancements during the past few years have provided oil manufacturers with ample reason to claim that good oils no longer wear out because of use, but that deterioration by various destructive agencies such as moisture, air, heat, oxidation, emulsification and electro-chemical action may have the effect of rendering the oil totally unfit for use"--page 1.

A Study In The Production Of Calendered Linoleum, Harry Simanton Pence

Professional Degree Theses

"The manufacture of similar products in two different plants results in duplication of effort, high production costs and difficulty in maintaining uniformity. The bringing of Philadelphia production of Battleship, Jaspe and Cork Carpet to the Trenton Plant will enable all calendered goods to be produced under single control, thus insuring uniformity and better supervision"--Introduction, page 8.
