Some Reactions Of 2-Chloroethanesulfonyl Chloride, Paul Zielinski

Theses

PART 1: THE FORMATION OF 2-METHYLAMIN0-N-0CTADECYLETHAHESULF0NAMIDE FROM 2-CHLOROETHANESULFONYL CHLORIDE. 2-Chloroethanesulfonyl chloride (2) was reacted with octadecylamine (3) in the presence of triethylamine to give N-octadecylethcnesulfonamide (4), which was reacted with methylamine to give 2-methylamino-N-octadecylethanesulfonamide (1). The first reaction involves formation of the sulfonamide and dehydrohalogenation. The second reaction is a Michael addition. The formation of 1 is favored in a polg.r, protic medium. An aprotic, less polar medium produces an unwanted di-Michael adduct CH3N(CH2CH2S02NHCl8H37)2 (8), and polymer. The intramolecular hydrogen bonded structure of 1 is discussed. PART 2: THE FORMATION OF ETHYL ETHENESULFONATE FROM 2-CHLOROETHANESULFONYL CHLORIDE OR ETHENESULFONYL CHLORIDE; A …

Identification Thresholds Of The Human Visual System For An Alphanumeric Resolution Test Object, Mark Bobb

Theses

Many investigations of the detection threshold of the human visual system have been conducted, and a few recognition threshold studies can be found, however no identification threshold data are available. This paper documents research on the observer's identification threshold for an alphanumeric resolution test object presented at various average luminance levels, contrasts, and contrast polarities. These factors affected the identification threshold in a similar way to the effects they exert on the observer's detection and recognition thresholds; the test object contrast being the most significant factor. Direct numerical comparisons between the various thresholds were not possible due to the large …

The Relationship Between The Relative Legibility Of Textual Material And Resolving Power In A Microphotographic System, John Compton

Theses

The application of microphotographic methods for the processing and storage of information has grown steadily during the last two decades. The microphotographic system, through which the information must pass at a minimum is as follows: Step 1: Photographing of the original document at a large reduction onto a silver halide microfilm. Step 2: Duplicating through contact printing onto a non-silver photographic material. Step 3: Second generation duplication onto a nonsilver photographic material (This image may be used on a microfilm reader). Step 4: Enlargement of the second generation duplicate to give a hard copy print. One of the main objectives …

An Integrated Approach For The Design Of A New Braille Printing System, Albert Barzilai

Theses

The braille production system is a slow and antiquated process. The end product is expensive, heavy, and bulky. A new, more efficient braille production system was designed, using computerized transcription, thermographic printing, and automated binding and finishing. Computerized transcription programs are readily available from a variety of sources; automated binding and finishing is a common feature of modern printing technology. A series of experiments was performed to evaluate the physical qualities of the braille cells produced by thermography. An internal tearing resistance test and machinability test were also performed to study the effect of heat on the paper stock. The …

The Correlations And Validity Of Selected Community College Curriculums To Graduate Placement In The Industrial Occupations Within Selected Graphic Arts Companies In The United States, Howard Rose

Theses

The purpose of this investigation was to question the validity of community colleges' occupational goals for graphic arts programs in the United States. To accomplish this, a statistical investigation was designed to either accept or reject the hypothesis of the thesis, which was: If a community college's educational objective in a graphic arts program is to prepare the student for a specific occupational area and level of occupation in the graphic arts industry, then upon successful completion of the program, a personnel director of a graphic arts firm would hire the student for that area and level of occupation for …

Optimization Of A Particular Aerial Photographic System By Simultaneous Intensification, Richard D. Young

Theses

Under the conditions of a low-altitude, rapid access photographic system, a method of simultaneously intensifying image exposures is compared to low intensity latensification. The simultaneous intensification resulted in a speed increase of 2.4 times, while latensification produced a speed increase of 1.7 times. Latensification was more effective in most of the other responses that were analyzed: reduction of Contrast Index was less by 0.1; speed at the minimum gradient point defined by the untreated strips was increased by latensification by 1.29 times compared to 1.23 times by simultaneous intensification. The detective quantum efficiency of the latensified film was higher than …

Current Flexible Rotor-Bearing System Balancing Techniques Using Computer Simulation, John Kendig

Theses

As the cost of machinery has risen and the need for dependability, safety and increased performance have in a similar manner increased, the needs of industry for viable flexible rotor balancing techniques has no less increased. Various flexible rotor methods have been advocated for supercritical shafting, but few studies or comparisons have appeared in the open literature. Among the procedures for balancing large and/or high speed (supercritical) rotors are the "N" modal method of Bishop and Gladwell, the "N + B" modal of Federn, the "N" and " + B" simultaneous modal method of Kellenberger, and the influence coefficient method …

Theses

The approximate physical model for solute-solvent inter?actions presented by J, M, Prausnitz and R, Anderson¹ is briefly discussed, Applicability of Weimer, Prausnitz³ and Helpinstill, Van Winkle⁷ models is investigated using experimental values of activity coefficients for C₅ hydrocarbons in 13 solvents including one nonpolar and 12 polar solvents. Independent correlations, based on our experimental values at 45°C for normal and isopentane have been developed. Although the required thermodynamic properties are obtained through a comparative analysis of all the available and estimated methods, dependable values of activity coefficients for Isopentane and 1-Pentene could not be obtained through …

Industrialized-Subsidized Housing In The Hackensack Meadowlands, Andrew Carl Gildersleeve

Theses

New Jersey as well as the rest of the nation is beginning to feel the pinch of what has been termed the housing crisis. The products of the World War II baby-boom are now reaching the age where they require homes of their own, making the demand for good quality low-cost housing very high. At the same time, the demand for good public housing continues to grow and we are learning that our previous efforts in this field have been far from satisfactory.

In the course of this study I have looked into the possibilities of solving a portion of …

Resolution Targets As A Measure Of Detail In Reproduction Of Engineering Drawings, Thomas Pratuch

Theses

The purpose of the experimentation was to abstract the problem of reading an engineering drawing so untrained observers could be used, and in so doing, find the minimum detail of drafted materials. Once the minimum detail condition was established, testing was to continue to find the procedures necessary to test for correlation between resolution targets and the minimum detail. The final goal was to reach a set of recommendations for further work and reduce the amount of unnecessary work for later experimenters. In short this paper was to help bring the testing of resolution and drafted materials to the same …

Correlation Of Drain Breakdown With Excess Noise And Other Surface-Related Phenomena In Enhancement Mosfets, Jerry J. Rij

Theses

An investigation of semiconductor surface-related phenomena has been undertaken to correlate 1/F noise with drain breakdown in P-channel enhancement MOSFET's. Increases in the intensity of drain current fluctuations at 10Hz and at 1KHz, particularly at the higher frequency, was observed following accelerated life-testing for threshold voltage drift. It was also concluded that mobile ions near the oxide-semiconductor interface produce a sharp increase in fast trapping centers. It was also found that 1/F noise intensity consistently peaked at the threshold of drain breakdown and that it steadily decreased with further increases in drain current. Of all the transistors tested, those with …

Rubbery Acrylic Polymer Adhesives, Steven Walter

Theses

This study shows how rubbery acrylic polymer adhesives can be used to adhere rubber substrates to each other. Two substrate rubber compounds were used. A styrene-butadiene copolymer and a styrene-acrylonitrile copolymer. The adhesives were homopolymers based on polybutyl acrylate and poly2-ethyl hexyl acrylate.

Two reference standards were used. The first was commercial rubber based, solvent cements. The second was commercial acrylic solution polymers. All experimental work was compared to these standards. An attempt was made to optimize the adhesive components, as well as the adhesive application procedures and curing conditions.

A primer coating consisting of polymer, monomer, and catalyst was …

The Quantitative Characterization Of Middle Distillate Fuels For Reduced Smoke Emission And Improved Low Temperature Operability, R. S. Feamster

Theses

Forty-eight inference equations are presented to approximate the hydrocarbon composition of middle distillate fuels and of the solids separating from these fuels at temperatures below their cloud points by consideration of fuel physical inspections. The physical inspections consist of API gravity, aniline point, cloud point, and distillation curves for ten fuels from major United States and European refineries. To determine the percentage of solids separating from cooled fuels, each fuel is filtered over a temperature range from the cloud point to -40 F in 10 F increments. Aromatic, naphthenic, and paraffinic hydrocarbon contents and the r-paraffin carbon number distributions of …

Investigations Of Color Balance Perception Of Photographic Images As Related To Their Surrounds, Robert Cosgrove, William Rabey

Theses

The perceived color balance of a photographic image as a function of its surrounds was investigated. Four images and three surrounds were used in all of their possible combinations. An image was projected onto a screen by means of a slide projector. A colored surround was projected by a second projector so that it encompassed the image. Five observers were asked to "correct" each image viewed within each surround to what he considered the most pleasing color balance. They did this by means of a three wheel subtractive filter system. (Cyan, magenta, and yellow)

The results showed that perceived color …
