The Factors Influencing The Price Of Metals On The Metal Market, Thomas Patrick F. Walsh

Masters Theses

"Every year the various engineering and industrial magazines print curves showing the rise and fall of metal stocks throughout the year. to the ordinary reader, these curves are seldom intelligible; he sees the ups and downs; he knows that the prices have risen and fallen; but he rarely knows what causes these changes -- and the curves themselves never tell. This paper tries to remedy this defect; it draws its curves, and, in the light of historical events, which it recounts, tries to determine the causes for the fluctuations in the market. it further places these factors on the curve …

Methyl Amines From Carbinol And Ammonium Chloride, Arthur Mark Howald

Masters Theses

"During the spring of 1919 we undertook to prepare tri-methyl-amine for the Research Department of the Eastman Kodak Company in the Industrial Chemistry Laboratory of the Missouri School of Minds. According to V. Merz and K. Gasiorowski the three methyl amines were qualitatively proven to be present in the reaction products obtained by heating methyl alcohol, ammonia and zinc chloride to 220°C. in a bomb for fourteen hours. As these raw materials are inexpensive we attempted to prepare the tri-methyl-amine by this reaction employing for the purpose a small industrial autoclave. Methyl amines were obtained by the yield especially of …

The Preparation And Physical Properties Of Benzene- And Toluene-Sulphonamides, Karl K. Kershner

Masters Theses

"The formation of sulphonamide derivatives is often of distinct importance. These substances are easily purified and give sharp mepting points which make them of value for identification phases of research work. Also they are of value commercially as in the production of saccharin and other similar compounds. The purpose of this investigation is to secure information on the comparative production and yield of sulphonamides, and intermediate products, formed from their respective ring hydrocarbons, as benzene and toluene. careful melting point are taken on purified products and solubility curves developed for different solvents. The latter give an interesting basis for comparison"--Introduction, …

The Relation Of Pyruvic Acid To Carbohydrate Metabolism., Sylvester Louis Schulte

Electronic Theses and Dissertations

It is known that carbohydrates on oxidation break into fragments which later are oxidised, or reduced, according as the conditions of the bodily functioning may favor, and it is in this process or reaction of the carbohydrate molecule that the formation of pyruvic acid probably takes place. From this point the pyruvic acid molecule on being fully oxidised would give the products carbon dioxide and water, and partial oxidation would give carbon dioxide and other products.

Der Junge Goethe., Evelyn J. Schneider

Electronic Theses and Dissertations

Das Leben "Des jungen Goethe" sollte eigentlich bis zur Zeit seiner vollen Reife zum Alter von etwa dreissig Jahren handeln, mit Hinzuziehen von allen Zustaenden, Ereignissen, und Leuten, welche irgend einen Einfluss bis dahin auf sein Leben, seine Entwickelung, und seine Gedichte hatten. Dieses wuerde un saber zu weit fuehren, deshalb beschraenken wir die Einfluesse auf Goethes Leben auf diejenigen, die vielleicht die bedeutendsten sing; naemlich, seine Liebesverhaeltnisse. Jedes von diesen machte seinen Eindruck auf Goethes Kunst, sodas seine Lebensbeschreiber es stets noetig finden, Schluesse von den Werken zum Manne, und vom Manne zu den Werken zu ziehen. Die reinsten …

The Chlorination Of Acetone., Marie Borries

Electronic Theses and Dissertations

This problem originated in an attempt to make methyl glyoxal in quantity. Several methods of making methyl glyoxal are mentioned in the literature but in none of them is acetone used as a starting point. Since this seemed a new field it was decided to chlorinate acetone hoping to obtain some product which might be easily converted into methyl glyoxal. Technical acetone was purified and dry chlorine was passed through this warm acetone in the presence of sunlight. During the process three distinct steps were noticed in the reaction. The first step was completed in the first half hour. During …

The Roasting Of Zinc Ores In The Manufacture Of Sulphuric Acid By The Contact Process, Clarence Eugene Peterson

Professional Degree Theses

"The unprecedented demand for sulphuric acid of the higher strengths (98% and higher) in the manufacture of explosives, has stimulated the zinc smelters to increased efforts in the recovery of their Roaster gases in the form of Sulphuric Acid. The Lead-chamber process is unsuitable, however, in making "strong" acid and the smelters naturally turned to the contact mass or catalytic processes. In the roasting of zinc ores practically all of the sulphur is removed as sulphur dioxide, the disagreeable odor and unmistakable injury to surrounding localities, of which, first led to the adoption of sulphuric acid plants by most zinc …

On The Microscopic Determination Of Cadmium In Metallic Zinc, James Presley Gill

Professional Degree Theses

"A quick and accurate determination of Cadmium in Metallic Zinc by all ordinary chemical methods now in use, so far as the writer has been able to ascertain is at best only approximate. However, longer methods and very delicate ones for determining Cadmium are in use that are very accurate, but these methods are so long and so delicate that very few commercial laboratories care to use them. Now, it has been known for some time that Zinc and Cadmium do not form an alloy which when in the solid exist either as a solution or a compound. They do …

Graphics And Its Application To The Progress And Cost Analyses Of A House Building Construction Company, Frank Lewis Leonard Wilson

Masters Theses

"In the graphical analyses of Stresses in Framed Structures, we study, by means of diagrams, the stability or equilibrium of structures and the relation between the external forces and the stresses created in the members of the frame. The principle involved is that we may represent any force both as to direction and intensity by a straight line, by considering the direction of the line to be identical with that of the force and adjusting its length according to any arbitrary unit adopted for the forces under consideration. By this means we can solve the stresses in framed structures with …

Frederick Steines, The First German Schoolmaster West Of The Mississippi : A Poet, Maria Elisabeth Steining

Theses and Dissertations

It has been my pleasure to study the life and works of Friedrich Steines to some extent. He is an interesting character for he was one of the strong pioneers on the western frontier in the days of 1834 when St. Louis was a small town. Especially is he interesting from an educational point of view because of hie progressive ideas and because he was the first German schoolmaster west of the Mississippi River. But he was not only a teacher. He has also left us a number of fine poems.

It is the purpose of this paper to give …

Simple Quantitative Determination Of The Non-Protein Portion Of Milk, Based On Greenwald's Modification Of The Determination Of The Non-Protein Nitrogen In Blood., Sarah Huntoon Vance

Electronic Theses and Dissertations

As far as I have been able to determine from the scant literature at hand, no attempt has been made as yet to determine the percentage of non-protein nitrogen in milk by a procedure simple enough for use as a clinical method. This problem was suggested to me by Dr. Charles J. Robinson, with the request that I should base my method on some of the methods of determination of the non-protein nitrogen portion of other physiological fluids.

Determination Of Critical Point Of Concentrating Tables On Arizona Copper Ore, J. C. Finagin Jr., W. C. Hogoboom

Professional Degree Theses

"In the concentration of an ore by means of concentrating tables, there is a critical point in sizing beyond which the valuable minerals can not be recovered. Theoretically, the lighter gangue is washed over the side of' the table and the heavier mineral, regardless of size, is recoverable at the end, these concentrates being graded from coarse to fine sizes up the slope of the table. In practice, however, the finer sizes of concentrates are found mixed with the middlings and tailings, as indicated by the arrows on the diagram of the concentrating table shown below. The problem is to …

Measurement Of Air Under High Pressure By Orifice Method, George E. Mellow

Bachelors Theses

"The measuring of compressed air, under high pressures, by means of observing the drop in pressure on passing thru an orifice, is in a new field of endeavor. The necessity of measuring compressed air, in order to handle it economically, is obvious. Hence, the importance of a simple device by which this may be done. A device, which may be duplicated at any time, at any place, with very little expense, and ordinary materials"--Introduction, page iii.
