The Presence Of Rhenium In Montana Manganese Ores., Henry E. Swanson

Bachelors Theses and Reports, 1928 - 1970

Rhenium properties offer many interesting possibilities, therefore any ores containing rhenium would be of considerable value. Its close relationship to manganese in the periodic table led to the belief that manganese ores would be an excellent place to search for the metal. Investigation of the literature of rhenium revealed that no ore was known to contain more than 0.001 per cent of rhenium.

Line And Grade Control Of The Subaqueous Midtown Hudson Tunnel, Lauren Preston Tuttle

Professional Degree Theses

"The entire system unifies all Preliminary Survey, Construction Control, and Independent Traverse work; bringing them under one common balanced system; thus, their precise relation is definitely established regardless of which side of the Hudson River the unit occurs. The establishing of a complete system is a subject within itself, and as this paper deals with the method of obtaining and carrying to completion the method of control for the river section of the tunnel, we shall limit our reference to the Triangulation system to the River Quadrangle"--Triangulation System. General, page 1.

Contact Metamorphism In The Highlands, Frank Trask Jr.

Bachelors Theses and Reports, 1928 - 1970

On the southern margin of the Boulder Batholith, about twenty miles south of Butte in the Highland Mountains, there are many miles of contact between the igneous and sedi­mentary rocks. As two kinds of igneous rocks and many diff­erent kinds of sedimentary rock are present, it is an excell­ent place for the study of contact metamorphism.

Microscopic Study Of Montana Silver Ores., Edwin Johnson

Bachelors Theses and Reports, 1928 - 1970

A microscopic investigation of the Montana silver minerals was conducted. This study consisted mainly of identifying the silver and silver-bearing minerals and of determining their paragenetic rela­tionships. The increasing amount of research in which the reflecting microscope is employed is evidence of the great value of this method of approach in the solution of problems of paragenesis of the opaque minerals.

Occurrence And Origin Of Placer Gold In Montana, John K. Halse

Bachelors Theses and Reports, 1928 - 1970

From time immemorial man has used gold as a medium of exchange, a mea­sure of value, as jewelry and for ornamentation. Placer gold has led dir­ectly or indirectly to the settlement of lands, California and Alaska being the two best known examples. It has led the way to the discovery of other important mineral wealth, the discovery of the copper and silver deposits at Butte, Montana and the discovery of the silver deposits at Cripple Creek, Colorado being two good examples.

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.

Return Flow Study Of The North Platte River, E. W. Carlton

Professional Degree Theses

"The investigation of return flow on the North Platte River, between Whalen, Wyoming and North Platte, Nebraska, was authorized by House Bill No. 308, "Flood control Act," Mississippi River and Tributaries, February, 28, 1929. The purpose of this study was to determine, if possible, the amount of return flow from the United States Reclamation Service "North Platte Irrigation Project", and its effect on the future development of irrigation in the North Platte Valley, flood control of the North Platte River, and it's ultimate effect upon navigation possibilities of the Missouri River. The particular phase of the above problem of which …

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 Rahway Valley Trunk Sewer And Its Relations To, And Effect Upon The City Of Rahway, Fred A. Hedeman

Theses

This treatise is divided into three separate parts, each portraying a particular phase of the Rahway Valley improvement. Although not directly connected with the Joint Meeting, the fact that I served as Assistant City Engineer in Rahway during 1931 and 1932 naturally presented to me the opportunity of attending meetings and studying the project especially as it pertained to the City of Rahway.

Part one is a general review of the activities of the Rahway Valley Joint Meeting, both prior to and after the completion of the trunk sewer. The second portion reveals some of the intricate problems evolving in …

Efficient Management Of Highway Projects Under State Administration, From The Point Of View Of The Project Or Resident Engineer, Jean Paul Bryan

Professional Degree Theses

"Efficiency in any project is an admirable attribute. It is even more than admirable in an undertaking designed for the spending of the taxpayer's money in which the lack of this trait is so liable to be interpretated [sic] as graft. It is necessary. After some eight years of connection with highway construction, a familiarity with inefficiency in the management of high projects under state construction is sufficient excuse, we believe, to warrant a dissertation of the opportunities for the practice of efficiency by those in direct charge of these project - the Project Engineers or the Resident Engineers, as …

Problems In The Cement Industry, William Alonzo Mccanless

Professional Degree Theses

"The major problem of the cement companies is the matter of marketing the product in sufficient quantities and at a price which will return a profit; however, there are some other problems that are of great interest to the engineers, i.e., the interest in the economics of cement based largely on its effect on the cost of contemplated structures"--page 1.

Playgrounds And Recreation Areas In Real Estate Subdivisions, Joseph L. Doyle

Bachelors’ Theses

With the coming of the machine age, the need of adequate playground and recreation areas in large cities is steadily increasing. During the past ten years, or more, congested cities have found it necessary to supply at any cost, playground and. recreation areas, for their people, who from year to year find that they have more and more leisure time at their disposal. In an unlimited number of instances the only way this could be secured was by buying valuable land, wrecking the buildings thereon, and thus provide open spaces for recreation at an enormous cost to the city. Had …

Asphalt Emulsions, Albert Joseph Krause

Bachelors’ Theses

During the past decade the improvement of our primary or trunk line highways and the streets of our business as well as the principal residence streets of our towns and cities has gone forward at a rapid pace. For the most part these improvements have consisted of high-type, costly pavements which have in some cases placed excessive burdens on our public treasuries and the tax-payers who are assessed for them.

The Public Health Engineer's Part On A Health Program, Walter Eric Casey

Professional Degree Theses

"In this work the Public Health Engineer should not be confused with the Sanitary Engineer as the term is commonly used today. The Sanitary Engineer is primarily a designer or builder. He is, in fact, a civil and hydraulic engineer specializing in a rather restricted field, confined for the most part to works relating to municipal water supply and sewage. The Public Health Engineer on the other hand is primarily a student and worker in the field of public health. The range of his activities is wider, and his training and knowledge are of essentially different character. It is not …

Concentration Of An Oxidized Lead Ore From Southeast Missouri, Robert Edward Evans

Masters Theses

"In the main ore bodies of the Southeast Missouri Lead Belt the lead occurs as galena disseminated in dolomite. The concentration in the mills is by tabling and flotation. The grade of the concentrates and the recovery of the galena are excellent. However, in certain areas of some of the mines ore has been developed that does not concentrate so readily. Because of its reddish brown color this ore is known locally as "red ore", and the presence of oxidized lead has been suspected. The purpose of this investigation was to determine the extent to which oxidized lead minerals were …

A Study Of The Plating Prohibitive Properties Of Various Separators, Bruno J. Pozorski

Bachelors’ Theses

The problem of this thesis is to study the plating prohibitive properties of the various materials commonly used in the manufacturing of separators, and to indicate which material would be most serviceable and feasible in a separator. At one time positives and negatives were kept not more than 0.25 inches apart, with the idea of reducing the intervening layers of electrolyte, and, therefore, the internal resistance of the cell, as much as possible. It was, however, found that the output could actually be increased by putting the plates at greater distances, the fact being that the larger bulk of solution …
