Adherent Electroplating On Molybdenum, Robert Marius Hansen

Theses

Molydbenum, due to its high temperature properties, and potential supply, is becoming a very important structural material, particularly in the field of electronics, however, it is not new in this part of industry. As temperatures go higher in various fields, the need for satisfactory materials becomes of paramount importance.

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

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 …

Preparation And Reduction Of Azo Dyes From 2-Amino Phenol-4-Sulfonic Acid, Guy J. Walker

Theses

Reduction of azo dyes is presented as a method for the synthesis of 2-amino phenol-4-oulfenic acid.

The synthesis and reduction of some azo derivatives of 2-amino phenol-4-sulfonic acid are described.

Preparation of the diazonium compounds of aniline, vitro aniline, 1-amino-2-nanhthol, 1-amino-2-naphthol-1-sulfonic acid, 2-amino phenol-4-sulfonic acid, 1-naphthol 1-amino, and 2-naphthylamine is discussed and their ability to couple with phenol-4-sulfonic acid evaluated.

Reduction of the resultant azo dyes is discussed with reference to fission and the benzidine rearrangement.

An overall presentation of results is Given in Tables I, II, and III on pages 27 - 29.

A Study In Emulsions, Edward Arthur Morse

Theses

An emulsion is a dispersion of one liquid in another liquid, the liquids being insoluble in each other. An emulsion consists of two phases, a continuous phase and a dispersed phase. The dispersed phase consists of tiny droplets or particles of one liquid which is completely surrounded by the other liquid comprising the continuous phase. One of the many factors affecting the stability of an emulsion is the size of the particle of the dispersed liquid.

This study is concerned with one emulsion prepared by different mechanical devices and under different conditions. The units of equipment employed are Eppenbach Colloid …

The Synthesis Of 2-Amino-4-Chlorophenol-6 Sulfonic Acid, Herman Albert Bronner

Theses

The work described in this thesis was undertaken with the view of exploring a reaction sequence suggested by early French investigators to synthesize 2-amino-4-chlorophenol-6-sulfonic acid especially in reference to the German claim that a low yield of product would result following this preparation, In particular, a successful application of this procedure would afford a relatively direct and inexpensive route to the sulfonic acid which is used as an azo dyestuff intermediate and could possibly find application in medicinal chemistry.

It was found that sulfonation and nitration of p-dichlorobenzene gave a high yield of the sodium-2-nitro-1,4-3 dichloro-benzene-6-sulfonate (91%) when using the …

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 …

Organic Ion-Exchange Materials, Harry Burrell

Theses

This thesis is offered as partial fulfilment for the degree of Chemical Engineer at the Newark College of Engineering. It covers a very new subject - one which has been rather intensively developed by several investigators during the past three years. The writer has had the fortunate opportunity of working on organic ion-exchange materials at the Ellis-Foster Co., which kindly gave permission through Mr. Carleton Ellis for the publication of experimental results. Many thanks are due to Dr. Frank B. Root, the laboratory director, whose gracious, constructive criticisms aided the writer in all phases of the work.

An attempt has …

The Incandescent Lamp, E. F. Tenbroeke

Theses

A brief history of the development of the incandescent lamp.

The Rahway Valley Trunk Sewer And Its Relations To, And Effect Upon The City Of Rahway, Fred A. Hedeman

Theses

This treatise is divided into three separate parts, each portraying a particular phase of the Rahway Valley improvement. Although not directly connected with the Joint Meeting, the fact that I served as Assistant City Engineer in Rahway during 1931 and 1932 naturally presented to me the opportunity of attending meetings and studying the project especially as it pertained to the City of Rahway.

Part one is a general review of the activities of the Rahway Valley Joint Meeting, both prior to and after the completion of the trunk sewer. The second portion reveals some of the intricate problems evolving in …

Problems Encountered In The Development Of An Airport, A. H. Armstrong

Theses

The progress of a nation and. its transportation facilities have always advanced hand in hand.

Just as it has always beerthe Civil Engineer's problem to develop facilities for other means of transportation, such as roads, harbors, and. railroad terminals, so is it his problem today to build airports.

In presenting the problems encountered in the development of an airport, the writer has considered the airport's place in city and regional planning, as well as the part it plays in air transportation.

An expression of thanks is given to Mr. Wm. S. La Londe, Jr., professor in Civil Engineering at the …

Piles And Pile Driving, Robert W. Van Houten

Theses

This thesis on the subject of "Piles and Pile Driving" has been written to fulfill one of the requirements for the granting of the degree of Civil Engineer by the Newark College of Engineering. The material contained in this thesis has been gleaned from many books, catalogs, magazines and from the author's own experience. Much still needs to be accomplished in the field of research but this can be done only through the cooperation of the companies who are engaged in this work and have the equipment necessary for making many tests under actual field conditions.

The author wishes to …

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 …
