Consumption And Uses Of Crude Barite And Its Derivatives, Peter Simonds

Masters Theses

"Barite is a widely distributed mineral composed of barium sulphate - BaSO₄. Its most striking feature is its weight - its specific gravity of 4.5 being about twice that of salt and many other of the colorless, transparent and vitreous minerals of its general appearance. The Mineral is usually found in a state of considerable chemical purity. However, small amounts of strontium and calcium sulphates may isomorphously replace the barium salt. Crystals of barytes are orthorhombic; usually very perfectly developed and have a wide variety of forms. The simplest crystals are rhomb-shaped tables bounded by two faces of a basal …

Electrolytic Reduction Of Galena In Fused Salt, Peter Simonds

Masters Theses

"A demand has long existed for a method of directly recovering elemental Sulphur, in addition to the Lead, from Galena ore. At the present time, the sulphur of this ore is dissipated in the lead blast furnace as sulphur dioxide fumes. While the fumes are trapped to avoid damage to the vegetation of the surrounding countryside, their concentration is usually too low to make sulphuric acid as a profitable by-product. Thus, contrary to some speculation, the sulphuric acid produces under the circumstances is usually not a true by-product in the money-making sense of the term in many cases, but a …

The Volumetric Determination Of Alumina In Clays And Related Materials, David Ferdinand Boltz

Masters Theses

"The primary purpose of this thesis was to develop a direct method for the determination of alumina in certain silicates. The classical gravimetric procedure for the analysis of alumina in clays and related materials has often been regarded as being too lengthy and troublesome, especially when only the percentage of alumina was desired. The correct determination of alumina is undoubtedly one of the most unsatisfactory of the chemical constituents of siliceous materials, and therefore the development of a direct volumetric method for the determination of this constituent was made the main objective of this research, page [1].

An Attempt To Correlate Certain Physical And Chemical Properties Of Various Commercial Animal Glues, Robert C. Andersen

Bachelors’ Theses

The manufacture and use of glue involves many important industries, and up to recent times we, in America, have lost much by our old "rule of thumb" and traditional methods for testing glues. In recent times much work has been done on a strictly scientific basis to explain the actions of glue from both a colloidal and a physicochemical aspect.

This thesis is concerned in particular with the possibility of coordinating the different properties exhibited by the accepted glue tests so that a definite criterion might be postulated for a high-grade animal glue. This task, however, proved extremely difficult, for …

A Study Of The Proteolytic Activity Of The Enzyme Papain On Various Brands Of Gelatine, Mary Christella Zeszuto

Bachelors’ Theses

The measurement of the ·viscosity of liquids by means of capillary tubes has been carried on for more than a hundred years. It was not, however, until 1846 that the results of Poiseuille's research were given to the public. For the comprehensive study he made of the problem, the concept of the laws controlling viscometry flow is attributed to him. The study of the same problem. was continued by many others in subsequent years. Their results, in general, verify the principles given by Poiseuille, but corrections attributed to conditions other than viscous flow have been suggested. These involve drainage, liquid …

A Method For Comparing And Measuring The Drying Time Of Glues, William C. Strutz

Bachelors’ Theses

The measurements or quality in glue testing are arbitrary and are of value only when compared to a standard glue or when comparing one glue to another. Glues have been used for hundreds of years, but it has been only in the last forty or fifty years that any scientific investigations of any consequence have been made. Prior to this time glues were made by rule of thumb by practical men who learned the art of glue making from other practical men in the business and by contact with the industry. "When the United States entered the Great War and …

Copper Chromium Oxide As A Catalyst In The Hydrogenation Of Castor Oil, Mary Sebaldus Rueger

Bachelors’ Theses

Catalysts are essential to most hydrogenation reactions. Very few hydrogenations occur in the absence of some sort of catalyst. Thus, the earlier work of Bergius on coal hydrogenation was non-catalytic, but more recently the process has become practically entirely catalytic thru the development of the I. G. Farbenindustrie in Germany.

A Comparative Study Of The Proteolytic Activity Of Trypsin On Various Gelatins, Louis Hinkle Coggs

Bachelors’ Theses

Since 1839, the viscosity of liquids has been measured by means of capillary tubes. However, it was not until the year 1846, that the results of Poiaeu1lle's research were :made known to the public. Because of the comprehensiveness of Poiseuille's work, the concept of the laws controlling viscometry flow is attributed to him. For one hundred rears the subject of viscometry has been studied by many. During these years the principle a propounded by Poiseuille have been verified in general, but various corrections and modifications of viscometers in regard to drainage, surface tension, liquid head, and kinetic energy have been …

A Remedial Program In The Four Fundamental Operations In Decimal Fractions, Hallie Ruth Weber

Master's Theses or Doctor of Nursing Practice

Can the results of the teaching of the four fundamental operations in arithmetic be improved? This is an important question that confronts most teachers of arithmetic. How can the teacher eliminate the difficulties which interfere with pupil progress, and reduce the number of failures in arithmetic? A group diagnostic test will show not only the level of ability of pupils in the various operations, but will point out weaknesses so that the teacher may organize her work in such a way as to give time to those who are below the standard and omit deadening drill for those who are …

A Study Of The Effect Of An Equal Energy Spectrum Upon Metallic Selenium In Vacuo, George Butler Scott

Master's Theses or Doctor of Nursing Practice

Since little has been found in the literature, on the effect of a actinic properties on the conductivity of metallic selenium and on its spectral response when possessing these properties, it was thought noteworthy to construct several selenium cells having low and medium dark resistances and to study them with a view of seeking some correlation between their conductivity characteristics and their prismatic response in vacuo.

The Propagation Of Ten Meter Radio Waves By Vertical And By Horizontal Dipole Antennas, James William Haddock

Master's Theses or Doctor of Nursing Practice

Radio communication is made possible by means of energy that travels through space from the transmitter to the receiver in the form of electromagnetic waves. These waves move with the velocity of light and differ from visible light only in wave length or frequency. This radiant energy consists of a magnetic field and of an electrostatic field, at right angles to each other and also at right angles to the direction of propagation. Questions explored in this thesis include: 1. Is there a relation between the amount of reflected radio energy and the angle of polarization. 2. If so, which …

Since the discovery of oil in Montana in1916, the petroleum industry has advanced to a point where over 5,000,000 barrels of oil worthover $6,500,000 has been produced in each of the three past years (1936, 1937, and 1938).

Remedial Work On The Division Of Decimals, M. Thomasine Schwind

Bachelors’ Theses

The important element in remedial strategy is the reduction of the necessity for it. Prevent more, so as to have to cure less! In all learning and especially in the processes of arithmetic, our attack must be based upon a four-fold basis. Each is affected by the other three. Initial learning, maintenance, measurement and remedial work are the four components of efficiency. before remedial work can be carried out efficient testing must be done.

The Bursting Strength Of Ethylcellulose Films In Various Organic Solvents, James B. Miller

Bachelors’ Theses

Since the discovery of celluloid by Hyatt, industry has appreciated the inherent toughness of compositions containing cellulose derivatives.

Ethylcellulose, one of the newest of these derivatives, has been widely used and investigated in the last few years because or its extraordinary properties which are unavailable in any other single cellulose derivative.

Electro-Dialysis Of Gum Arabic By Means Of A Continuous Flow Apparatus, Jerome J. Kowalski

Bachelors’ Theses

This work was performed with the intention of devising a method for the electro-dialytlc separation of electrolytes and colloids which provides for the continuous flow of sol and dialysate during the process.

The facts which were instrumental in directing the author's attention to this problem are: (1) The lack of a simple and efficient apparatus for electrodialysis, and (2) the wide range of possibilities for the application of such a device.
