Testing The Fisher-Foser Mark-I On-Easel Color Analyzer, C. Donald Fisher, Richard Foser

Theses

It is proposed to test and statistically evaluate the performance of an on-easel color analyzer built by the authors. It is discovered during the testing program that the device is nonfunctional, and the testing program is re-directed toward finding the causes of the instrument mal-function. It is concluded that the particular characteristics of the cadmium sulfide cell employed, and the electronics of the device, introduce non-linearities which make readings non-repeatable. It is nevertheless felt that the concepts involved in the device, and in the testing program as originally envisioned, are sound, and that further development of the device would produce …

Variations In The Spectral Radiometric Function, Measured In The Field, Of Five Different Types Of Terrain As A Function Of Atmospheric Conditions, Solar Altitude, And Viewing Position, Guy Welch

Theses

The purpose of this experiment was to: 1. Determine how closely five different types of terrain, such as sand, cultivated soil, grass, loose rocks, and bushes resembled Lambertian surfaces. 2. Determine how closely the radiometric functions for three wave length bands compared for each type of terrain. 3. Develops the shape of the radiance envelope as defined by the radiometric function for each type of terrain. 4. Determine the effect of changes in solar altitude on the radiometric function. 5. Determine the effect of changing the conditions of irradiance from clear sky to overcast sky on the radiometric function. The …

A Multi-Exposure, High Resolution Camera For The Production Of A Resolving Power Test Target, With Extended Range, Richard Bergen

Theses

Since 1888, a series of mutually perpendicular lines have been used as a test object for evaluation of optics, systems, products, etc. The availability of such test objects has traditionally been in the frequency range of about one cycle per millimeter to a couple hundred cycles per millimeter. These have been available from a few manufacturers, none of which offers the extended range of .25 cycles per millimeter to greater than one thousand cycles per millimeter proposed in this project. The usefulness of such an extended range serves to make it an all-purpose test target for measurement of enlarging, contact …

Vapor-Liquid Equilibria System : Chloroform, Carbon Tetrachloride, Isopropanol, Barnet H. Bursack

Theses

A study was made of the vapor-liquid equilibria of the ternary system: Chloroform (CHCl₃), Carbon Tetra-chloride (CCl₄) and Isopropanol (C₃H₈O). An Othmer still was used for the equilibria determination. Refractive index and density measurements were used to determine liquid and vapor compositions. A comparison between experimental and theoretical values was made using the Margules 3-suffix ternary equations for the correlation.

It was necessary to investigate the vapor-liquid equilibria of each of the three binary systems to evaluate the techniques and equipment used and obtain new data. Only one previous investigation of the …

The Kinetics Of A Heterogeneous System, Francisco H. Fernandez-Ortega, Gonzalo D. Milian

Theses

The reaction between an acidic potassium dichromate solution and metallic copper has been studied at 25.0°C under batch quiescent and continuous flow conditions.

The effect of time of reaction, reactor diameter, acid, dichromate, and salt concentration upon reaction rate have been investigated for a quiescent batch reactor and found to influence the Reaction Velocity Constant of the system. As the reaction progressed, the Reaction Velocity Constant was observed to decrease. An increase in reactor diameter resulted in a Reaction Velocity Constant increase. Small increments in the dichromate concentration produced a decrease in the Reaction Velocity Constant. A maximum point of …

Kinetics Of Hydrolysis Of Butyl Lactate, Peter Pommers

Theses

The acid catalyzed hydrolysis of butyl lactate with water, using lactic acid to achieve a homogeneous solution, was studied.

Experiments at various temperatures were run under catalyzed and uncatalyzed conditions. The course of the hydrolysis was followed by titrating the acidity of the reaction mass at certain time intervals. From the results of these titrations and from the experimental determinations of the equilibrium constant, the reaction velocity constants for the hydrolysis of butyl lactate were calculated. The velocity constants were found to range from .8 x 10^-5 to 25 x 10^-5 liters/ (g-mole)(min), depending upon the reaction temperature …

Current-Potential Effects Of Trace Impurities In Manganese Electrowinning-Ii, Bipinchandra Govindlal Shah

Theses

The effects of trace non-metallic impurities, found in manganese electrowinning solutions, on cathode current-potential curves have been investigated. Five impurities, e.g., Sulfur-dioxide, Ammonium Sulphide, Urea, Thiourea, and Gelatine were studied.

In the first phase of the study the effect of individual impurity on the standard polarization curve was determined for a range of concentration. It was observed that these impurities did not affect the standard polarization curve.

In the second phase the above observation was confirmed by using cobalt as metallic impurity in addition to the non-metallic impurity. A marked effect on the standard polarization curve was observed due to …

Diffusion Coefficients In Alcohol - Water, Frank Gustav Meier

Theses

Diffusion coefficients of potassium, calcium and magnesium ions in ethanol-water solutions have been determined at 20°C. by means of Dowex 50W-X8 under experimental conditions that indicate that the transfer rate is controlled by film diffusion.

This investigation presents, for the first time, diffusion coefficients for these ions in ethanol solutions at concentrations below 0.01N.

The combined effect of viscosity and dielectric Constant of the solvent on the diffusion coefficient of Ions is demonstrated.

Effects Of Non-Constant Molal Flow On Distillation Plate Separation, Joseph Lawrence Niedzwiecki, W. Weissman

Theses

This thesis presents new equations for predicting degree of separation on a distillation plate, recognizing non-constant molal flow effects. A FORTRAN program is included for solving the new equations. Experimental runs were made for comparison to theoretical predictions.

First an equation is derived for predicting separation at a point on a distillation plate. The derivation is analogous to Murphree's point efficiency equation except that the effects of flow between phases are included by applying the Colburn-Drew theory. Finally, an overall plate separation equation is derived analogous to the A.I.Ch.E. eddy diffusion model for Murphree plate efficiency, except that the rate …

Latent Image Stability In High Resolution Plates, Robert Mottice

Theses

A study of the stability of the latent image in High Resolution Plates is presented. Two factors have been investigated- relative humidity before and after exposure and the length of time under such conditions. It was found that in conditions of 60% relative humidity or less, fading does not pose any real threat to the commercial user and that under 100% R.H. conditions fading takes place quite rapidly.
