A Study In Elementary Schools In 1946 Of Twenty-Six Children Who Attended Mental Hygiene Clinic Nursery School, Louisville, Kentucky In 1939-1942., Ann Coleman Dec 1946

A Study In Elementary Schools In 1946 Of Twenty-Six Children Who Attended Mental Hygiene Clinic Nursery School, Louisville, Kentucky In 1939-1942., Ann Coleman

Electronic Theses and Dissertations

This study is an attempt to follow the development of the group of children who attended the Mental Hygiene Clinic Nursery School of Louisville, Kentucky in its first three years, September, 1939 through May, 1942. The children were studied on a comparative basis of their behavior in the two school situations - nursery school in 1939-1942 and elementary school in 1946. The study not only considers the child's behavior in the classroom, but also attempts to evaluate the effects at personality and environmental influences upon the child's school adjustment - his health, conditions in the home, and mental development. The …

The Surface Impregnation Of Wood : Ii. Use Characteristics Of Impregnated Wood : Iii. Investigations Of Resin Adhesives., John V. Birkel Dec 1946

The Surface Impregnation Of Wood : Ii. Use Characteristics Of Impregnated Wood : Iii. Investigations Of Resin Adhesives., John V. Birkel

Electronic Theses and Dissertations

This thesis is divided into three parts: I. The Surface Impregnation of Wood; II. Use Characteristics of Impregnated wood; and III. Investigations of Resin Adhesives. The material presented in Part I is a continuation of previous experimentation that had established general methods for producing a hardened surface wood product. The methods involved parting of the wood fibers on the surface by a special serrating tool, followed by a surface impregnation and final curing. This section presents work carried on to determine the optimum conditions for serrating and subsequent impregnation. The effect of species on impregnation. and the impregnation of unfinished …


Improved Techniques For Washing Iron Blue Suspensions : Ii. The Preparation Of O, O'-Dichlorobenzidine From O-Chloronitrobenzene., Marvin L. Gernert Dec 1946

Improved Techniques For Washing Iron Blue Suspensions : Ii. The Preparation Of O, O'-Dichlorobenzidine From O-Chloronitrobenzene., Marvin L. Gernert

Electronic Theses and Dissertations

I. IMPROVED TECHNIQUES FOR WASHING IRON BLUE SUSPENSIONS

The investigation of several procedures for the speeding of the washing of iron blue suspensions to remove electrolytes is reported. The use of several techniques to coagulate blue particles in the colloidal range to cause more rapid settling was found to be of little value. A conventional Oliver filter and centrifugal clarifier were found to be unsatisfactory for clearing iron blue suspensions. Considerable advantage in washing by settling and decantation was obtained with the settling of the blue suspensions in relatively shallow vessels. A continuous washing procedure was developed whereby the blue …


Ethylcellulose Lacquer Coatings For Polystyrene Plastics., Stuart V. Heil Dec 1946

Ethylcellulose Lacquer Coatings For Polystyrene Plastics., Stuart V. Heil

Electronic Theses and Dissertations

An ethylcellulose lacquer system for both decorative and protective purposes was developed for use on polystyrene plastics. It was found that a one-coat lacquer containing only alcohol solvents produced the most satisfactory finish. Formulations were based on experimental work, conducted to determine the effect of the various lacquer components on the plastic. The results of a study of formulations on a two-coat system are presented.


A Graphical Solution For Batch Steam Distillation Of A Binary Mixture., Howard D. Carlson 1921- Jun 1946

A Graphical Solution For Batch Steam Distillation Of A Binary Mixture., Howard D. Carlson 1921-

Electronic Theses and Dissertations

The theory for the graphical solution of batch steam distillation of a binary mixture is presented and illustrated. The results obtained from this graphical procedure are compared with actual experimental results. The comparison showed very close agreement between the graphical results and the experimental results. Three sets of experimental data are shown for benzene-bromobenzene mixtures and one complete set for benzene-toluene mixtures.

Surface Impregnation Of Wood : Ii. Gaseous Impregnation Of Wood : Iii. Investigations On Submarine Decking : Iv. Investigation Of Marine Adhesives., Otto J. Mileti

Electronic Theses and Dissertations

This thesis presents results on methods used to produce a hard surfaced wood product. The methods involve the parting of the wood fibers on the surface by a special serrating tool, followed by surface impregnation and final curing. The serrations on the wood surface produce an artificial grain upon curing. A preliminary investigation was made to improve the rot-resistance of wood by gaseous treatment. Results of such treatments show some limited success with formaldehyde on yellow poplar and warrant further study. An investigation was made to find a substitute for teak wood used on submarine decking. A number of combinations …


A Descriptive Study Of The Guidance Services In Operation At Two Secondary Schools Of Louisville, Kentucky., Mary Edna Brown Jun 1945

A Descriptive Study Of The Guidance Services In Operation At Two Secondary Schools Of Louisville, Kentucky., Mary Edna Brown

Electronic Theses and Dissertations

Statement of the Problem. The purpose of this study is threefold. An attempt will be made, 1. to present and defend sixteen principles underlying an adequate guidance program for secondary schools, 2. to describe as accurately as possible, the activities of guidance that operate in two of Louisville's secondary schools, 3. to offer suggestions and to encourage administrators and teachers of these two schools, to submit recommendations, which might help to establish successful guidance services in their particular schools and which might eventually result in the organization of an adequate Guidance Program for Secondary Education in Louisville. Reasons Why Subject …


Heat Transfer To Fuel Oil In Viscous Flow-Characteristics Of A Fin-Type Heat Exchanger., Boyd R. Abbott Jr. Jun 1945

Heat Transfer To Fuel Oil In Viscous Flow-Characteristics Of A Fin-Type Heat Exchanger., Boyd R. Abbott Jr.

Electronic Theses and Dissertations

A unit was constructed for the study of film heat transfer coefficients of a heavy fuel oil in viscous or streamline flow. The heat exchanger was of the shell and tube type, having extended longitudinal steel fins welded to the tube. Auxiliary equipment consisted of an oil pump, oil storage reservoirs, piping, and means for measurement of temperatures and oil flow rates. The unit was operated both as a fin type heat exchanger with the oil in contact with the finned surfaces, and as a straight tube and shell exchanger with the oil on the tube side. Oil flow rates …


The Reaction Of Ethylcellulose With Fatty Acid And Its Application To The Varnish Industry : Ii. Ethylcellulose In Pencil Lacquers., Albert L. Kimmel Feb 1945

The Reaction Of Ethylcellulose With Fatty Acid And Its Application To The Varnish Industry : Ii. Ethylcellulose In Pencil Lacquers., Albert L. Kimmel

Electronic Theses and Dissertations

Ethylcellulose was refluxed with Stearic, Oleic, Linseed Fatty acids, and a neutral Mineral Oil in the presence of a solvent. The products recovered were analyzed to determine if any possible reaction had taken place. Conditions for the reaction were carried out so that the temperatures obtained could be in the near range of varnish cooking, that is between 375 and 500°C. The I solvents used were diethylbenzene, boiling point 180oC and tetralin, boiling point 208oC. In each case approximate stoichiometric proportions of the fatty acids and ethylcellulose were used. These were refluxed to a sensible minimum viscosity of solution. The …

The Development Of Ethyl Cellulose Lacquers For Automotive Use : An Ethyl Cellulose Lacquer For Coating Plastics., Robert Carlton Krueger Oct 1944

The Development Of Ethyl Cellulose Lacquers For Automotive Use : An Ethyl Cellulose Lacquer For Coating Plastics., Robert Carlton Krueger

Electronic Theses and Dissertations

There have been developed various colored ethyl cellulose lacquers that compare favorably with standard nitrocellulose lacquers in physical tests. Ultra violet light caused rather pronounced darkening of the lighter colors such as white and light yellow, probably because of the use of high amounts of phenolic resin. Also because of the presence of relatively large amounts of phenolic resin, the cost was somewhat higher than a comparable nitrocellulose lacquer. Suggestions for further work and improvement are included. An ethyl cellulose lacquer has also been developed to be applied by spray or brush to ethyl cellulose plastics with a minimum amount …
