A Study Of The Cooling Curve Of Several Waxes And Various Binary Mixtures Of These Waxes, Casimir A. Smyk
A Study Of The Cooling Curve Of Several Waxes And Various Binary Mixtures Of These Waxes, Casimir A. Smyk
Bachelors’ Theses
A cooling curve may be defined as a graphic representation of the relationship which exists in the elapse of time and temperature of a substance surrounded by a medium of a temperature lower than itself. There is no heat added to the substance and the only heat taken away from the substance is by means of the surrounding medium. It is time plotted against temperature. Time on the x-axis and temperature on the y-axis. Many methods have been mentioned for the determination of purity and identification of a wax. But the methods are not standardized because of the length and …
The Effect Of Halowax On Lubricating Oil And Grease: The Instability Of Aluminum Grease In Regard To Viscosity, Nathan Smith
The Effect Of Halowax On Lubricating Oil And Grease: The Instability Of Aluminum Grease In Regard To Viscosity, Nathan Smith
Bachelors’ Theses
This thesis is concerned with lubricating oils and solid lubricants. The initial problem in this research was the effect of Halowax 1012, 1013, and 1014 on lubricating oil. During the investigation, however, it was observed that the addition of Halowax to the lubricating oils formed a false gel at ordinary temperature, the consistency depending on the percentage of Halowax added. The result no longer favored continued research since the lubricating oil was made impractical. The problem then lent itself to the influence of Halowax on solid lubricants, in particular lubricating greases. It was on this phase of the investigation that …

Mathematical Instruments, Marguerite Massey
Theses & Honors Papers
The selection of a subject for my honors work was determined not only by the desire to gain a broader knowledge of mathematics but also to make a study of something that would be of value in teaching in the state. From a variety of possible topics, the one, mathematical instruments seemed most interesting and appealing. This broad subject had to be narrowed down and made more specific. It was decided to limit it mainly to those instruments which might be used in the teaching of mathematics, these falling into two groups, those which can be made and those which …

The Making Of Models To Illustrate The Principle Of Plane Polarized Light And The Phenomenon Of Double Refraction., Milton A. Sizer
The Making Of Models To Illustrate The Principle Of Plane Polarized Light And The Phenomenon Of Double Refraction., Milton A. Sizer
Bachelors’ Theses
When the author took a course in Optics, and came into contact for the first time with the subject of polarized light and double refraction, he found it exceedingly difficult to visualize the various phenomena which took place. The advantage could easily be seen, of mechanical models made to illustrate the passage of light through glass and other crystals. The object of this thesis is to describe the making of mechanical models which are to be used in teaching the subject of polarization of light.

A Study Of Methods For Separating The Elements That Interfere In The Electrolytic Deposition Of Lead As Lead Oxide, John Shaw Sabine
A Study Of Methods For Separating The Elements That Interfere In The Electrolytic Deposition Of Lead As Lead Oxide, John Shaw Sabine
Masters Theses
"The electrolytic determination of lead as lead dioxide is a very desirable method, due to its simplicity, accuracy, and the small amount of the analyst's time required. The electrolytic method functions when both large and small amounts of lead are present. The method depends upon the fact that from a nitric acid solution the lead is plated upon the anode as lead dioxide; from the lead dioxide deposit the percentage of lead may be calculated.
An electrolytic method, for determining the lead in samples containing from 5 to 150 mg. of lead, was described in a paper by Schrenk and …

The Preparation And Specific Gravity Of Pure Formic Acid And Its Aqueous Solutions, Leo Henry Merchie
The Preparation And Specific Gravity Of Pure Formic Acid And Its Aqueous Solutions, Leo Henry Merchie
Masters Theses
"Formic acid, the lowest member of the fatty acid series, was obtained as early as the seventeenth century by distilling ants with water. Other methods were later found after the correct constitution of the acid became known. This acid is not difficult to prepare in a water solution, but it is difficult to obtain in the anhydrous state...The purpose of this work is to study the various methods of preparing anhydrous formic acid, to improve a method for preparing the anhydrous acid, and to correct specific gravity tables for aqueous solutions of formic acid"--Introduction, page 1-2.
Wax Analysis With Special Reference To Montan, Spermaceti, And Chinese Insect Wax, Margaret M. Plonsker, Margaret E. Seippel
Wax Analysis With Special Reference To Montan, Spermaceti, And Chinese Insect Wax, Margaret M. Plonsker, Margaret E. Seippel
Bachelors’ Theses
The presentation of this thesis under joint authorship finds its justification in the fact that much of the experimental work, though performed individually, is of such a nature as to warrant a unified description. In this way the reader is afforded a better representation and clearer conception of the problem, and a substantial guide for further investigation. Though much work has been done in the field of wax analysis, little is known of the higher fatty acids and alcohols of many of the waxes. Their isolation has been infrequent, and few if any of their derivatives have been formed. It …
