Viscosity Determination During Polymerization, Elmer David Jones
Viscosity Determination During Polymerization, Elmer David Jones
Theses
This project was undertaken for the purpose of designing, constructing, and operating a viscometer which could be employed for measuring viscosities in the range of 200 to 700 poises at temperatures up to 300°C. Such an instrument was built and used to study the viscosity of Type EV polymer during polymerization.
The new viscometer is based cm the principle of concentric rotating cylinders. It is unique in that it can be suspended directly in a polymer batch and will operate under temperature and viscosity conditions as outlined above. Polymerization curves for batches studied show that the instrument gives viscosity values …

Heat Transfer Characteristics Of Non-Newtonian Suspensions, Robert Gregory Quinn, Irving Bauman
Heat Transfer Characteristics Of Non-Newtonian Suspensions, Robert Gregory Quinn, Irving Bauman
Theses
This project was undertaken to collect additional information on the heat transfer coefficients of pseudo-plastic suspensions and to test the exponents of the equation of Salamone (12). Using the same equation as derived by Salamone by dimensional analysis, a better correlation of this data was obtained by changing some of the exponents to give the following equation:
LD/Kf=0.346(Dvp/M`)0.7(CfM`/Kf)0.72(Ds/D)0.15(Cs/Cf)0.35(ks/kf)0.08 (1)
The authors believe that a better correlation is possible and …

Heat Transfer Characteristics Of Non-Newtonian Suspensions, Harold Binder, Paul Pollara
Theses
The following equation was developed by Dr. J. J. Salamone for calculating the fibs coefficient of heat transfer to non-Newtonian suspensions in turbulent flow (Re 50,000 - 200.000) inside of pipes:
hD/Kf = 0.131 (DVbPb/ub)0.62 (D/Ds)0.05 (Cs/Cf)0.35 (Cfub/Kf)0.72 (Ks/Kf)0.05
This equation was investigated to determine its validity over the lower turbulent regions of the Reynolds number (10,000 - 70,000), and to test the exponents of the various components.
Equipment was constructed similar …

Investigation Of The Acid Degradation Of 2-(4-Methoxybenzylamino)-Pyridine, Anthony Thomas Oropollo
Theses
This paper represents work done in connection with an investigation of the products resulting from the reaction of dilute sulfuric acid and 2-(4-methoxybenzyl-amino)-pyridine. Brief contact between these reactants at temperatures below 80°C give rise to a water soluble salt of the amine. The amine may be precipitated from the solution by the addition of sufficient alkali.
Under the conditions considered in this paper, prolonged contact of reactants at temperatures above 80°C, a non-crystalline condensation product is obtained in addition to the amine salt.
Attempts to identify this product were unsuccessful. However, in connection with the characterization work, two relatively little …

The Effect Of Surface Tension Upon The Flow Of Fluids Through Packed Beds, William Charles Streib
The Effect Of Surface Tension Upon The Flow Of Fluids Through Packed Beds, William Charles Streib
Theses
Flow tests through beds of unconsolidated sand, glass beads and 1/4 inch Berl saddles showed that wide variations in the surface tension of a fluid had no significant effect on its flowrate through the bed. Viscosity and density were the only fluid properties affecting such flow. Excellent comparative results were observed between the flowrates through sand beds and those predicted by the Leva equation.
The complex Brownell and Katz equation for predicting the residual saturation of a packed bed was found to apply for fluids having a much wider range of surface tension than those originally used to derive their …

Ultrafiltration In The Pigment Field : A Critical Literature Survey, Charles Walter Manger
Ultrafiltration In The Pigment Field : A Critical Literature Survey, Charles Walter Manger
Theses
The objective in this work has been to determine, through a critical literature survey, the possible application of ultrafiltration, and other related techniques, towards the solution of certain problems encountered in the research and testing of various pigments.
Among these problems may be mentioned the following:
- The determination of water-soluble salts in pigments, which when dispersed in water to leach out the salts, tend to peptize, thus being unfilterable through the usual filter paper. Among these pigments are the following: iron blue, certain chrome yellows, pigment green B, copper maroon, and several others. It may be added that these pigments …

One of the ways in which to overcome the disadvantages of poor stability, brazing difficulties, and surface resistance to high frequency conduction, is by electroplating. Until recently there has been no satisfactory method for obtaining adherent deposits. The purpose of this report has been to investigate these recent processes and devise …
Cost Reduction Through Closer Control Of Quality, Walter Robert Kuzmin
Cost Reduction Through Closer Control Of Quality, Walter Robert Kuzmin
Theses
The economy of our nation differs today from that of World War II or pre-World War II days by the fact that a war-production program is being carried on without adversely affecting the production or civilian goods, At the same time management is confronted with rising costs due to the inflationary spiral of wanes and materials. To mire a profit on Products and remain in competition, management is forced to apply the latest cost reduction methods. Because of the dual economy, companies are quoting on civilian goods and war Products. Contracts released by the government specify that; adequate inspection and …
Waterfront Construction In New York Harbor, Carman William Garrison
Waterfront Construction In New York Harbor, Carman William Garrison
Theses
The following chapters are devoted to the various phases of that branch of construction which is followed from the offshore side of the waterfront. This branch, in the parlance of the building trades, is known as dockbuilding. Years ago all waterfront structures in New York Harbor were constructed almost entirely of timber and experience taught that the most economical approach for building docks and wharves was made by utilizing floating piledrivers and derricks. Thus it happened that dockbuilders became skilled both in the use of wood framing tools and in handling marine equipment. Modern dockbuilders must have, in addition to …

Cuprous Oxide Rectification, Philip G. Cobb
Cuprous Oxide Rectification, Philip G. Cobb
Theses
It has been shown that cuprous oxide, when formed from a copper surface by suitable heat treatment, has remarkable rectifying properties towards alternating voltages applied through the oxide and copper. The purpose of our work was to investigate, the effect fully from all angles possible, and especially from those considerations affecting the constancy and permanence in the electric circuit.
The work ranged from furnace operation to tests of completed units, and further to the development of a theory explaining as completely as possible this rectifying property.
It soon became apparent, that here was ideal thesis material, and so, with proper …
