Investigation Of The Emulsifying Properties Of Iso-Electric Gelatin, Ellsworth Warren Hudgens Jan 1949

Investigation Of The Emulsifying Properties Of Iso-Electric Gelatin, Ellsworth Warren Hudgens

Masters Theses

"A considerable amount of work has been done on the use of gelatin as a stabilizer or as a protective colloid in emulsions, or in other colloidal systems. However, relatively little research has been published using gelatin solely as an emulsifying agent. With this in mind it was decided to investigate the emulsifying properties of iso-electric gelatin with water - oil systems. The term oil, as used, refers to any liquid immiscible with water. It has long been known that gelatin would form dual type of emulsions with certain "oils" by varying the phase volume ratio of the two liquids. …


The Electrolytic Recovery Of Silver From Waste Silver Residues, Bailey Warren Hagar Jan 1949

The Electrolytic Recovery Of Silver From Waste Silver Residues, Bailey Warren Hagar

Masters Theses

"A considerable amount of silver is contained in the silver chloride-silver thiocyanate residue resulting from the use of silver nitrate and potassium thiocyanate by students of quantitative analysis in the volumetric determination of chlorine. The main objective of work described in this paper, therefore, was to find a simple and efficient method for recovering the silver from this silver chloride-silver thiocyanate residue...it was hoped that the experimentation described in this paper might also result in the design of inexpensive equipment which might be used by the small photographic shop"--Introduction, page 1-2.


Further Studies - Heat Transfer Coefficients For Liquids In Forced Convection Normal To Banks Of Staggered Tubes, Terrell C. Claunch Jan 1949

Further Studies - Heat Transfer Coefficients For Liquids In Forced Convection Normal To Banks Of Staggered Tubes, Terrell C. Claunch

Masters Theses

"The problem for these experiments may be divided into two sections. The first section of the problem consists of setting up procedure for duplicating data. The second section is that of studying and explaining characteristics of the resulting curves. Correlation of the data obtained will be necessary in order to obtain the curves. In order that the first section of the problem could be solved it was necessary to establish a standard of cleanliness for the apparatus used. Establishment of procedures for the operations and cleaning of the apparatus was necessary. Before Kenneth E. Rudert began his design and construction …


Design Of A Barge-Platform Marine Drilling Rig, Ely Schwartz Jan 1949

Design Of A Barge-Platform Marine Drilling Rig, Ely Schwartz

Masters Theses

"ln the quest for oil in the Gulf of Mexico, princi­pally off the coasts of Texas and Louisiana, unique types of drilling rigs able to cope with environmental conditions have been developed in the last several years. This development is highly specialized and has led to methods of operation revolutionary to the oil industry and is without precedent….

In designing a drilling platform there are three cardinal aims (1) low cost installation and operation, (2) ease of operation, (3) providing safe working condi­tions.

The initial problem is to extend the shore-based fabrication and reduce the offshore construction, foul weather delays, …
