A Study Of The Plating Prohibitive Properties Of Various Separators, Bruno J. Pozorski

Bachelors’ Theses

The problem of this thesis is to study the plating prohibitive properties of the various materials commonly used in the manufacturing of separators, and to indicate which material would be most serviceable and feasible in a separator. At one time positives and negatives were kept not more than 0.25 inches apart, with the idea of reducing the intervening layers of electrolyte, and, therefore, the internal resistance of the cell, as much as possible. It was, however, found that the output could actually be increased by putting the plates at greater distances, the fact being that the larger bulk of solution …

Electrodeposition Of Rubber Upon An Electrode By Means Of A Direct Current Of Electricity, L. F. Novotny

Bachelors’ Theses

The rubber industry may be said to be one of the most speedily developed industries in the world. This is due to a great extent to the fact that the first real interest in rubber as a material of commerce came in the advent of the automobile. It was in 1888 that an Irish horse doctor, John Boyd Dunlop, conceived the idea of tying a rubber tube around the wheels of his little son's velocipede. Within seven years of this event, a $25,000,000 corporation was manufacturing Dunlop tires.

Something may also be said here of the man who took the …

Selection And Arrangement Of Proposed Storage Battery Equipment For Physics And Electrical Engineering Laboratories, Otho Melvin Wilson

Transmission Of Electrical Energy At 220,000 Volts, Robert Wilhelm Ahlquist

Bachelors Theses

"A. E. Silver at the Annual Convention of the A.I.E.E. in 1919 gives some of the reasons why 220,000 Volt transmission is a logical and feasible commercial proposition. He also gives some of the main features of the undertaking...Owing to the great scope of this paper it has been thought necessary to generalize on the discussion of the first two topics and to treat the next two in more detail"--Statement of Scope of this Paper, pages 3-4.

The Outdoor Substation, Israel Herrick Lovett

Professional Degree Theses

"The Outdoor Substation, as an essential part of a high voltage distribution system, has been largely developed during the past 12 years. The New England Power Company was one of the pioneers in this development, their substation at Millbury, Massachusetts, being one of the first outdoor substations in the northern part of the country. During the five years' experience with this company, the writer of this thesis, in his position of Chief Electrical Designer, was partly responsible for the design of all substations constructed by the company during this period, from 1916 to 1921...This thesis is an account of the …

A Discussion Of Electric Welding, Peter Fergus Thompson

Bachelors Theses

"This thesis deals with the different processes, methods and uses of Electric Arc Welding; and tests made in the laboratory with Direct and Alternating Current"--page iii.

An Experimental Study Of The Cathode Fall In Helium And Argon With Wire Cathodes, L. G. Raub

University Studies (University of Nebraska) (1888–1984)

It was recognized rather early in the study of the phenomena of discharge of electricity through gases that the ordinary laws of conduction as found in solid and liquid conductors are not applicable to gases. It was shown by Zeleny and independently by Child that Ohm's law by no means represents the distribution of potential between electrodes in an ionized gas, but that the potential gradient is large in the vicinity of the electrodes, and not uniform throughout the space between them. When the pressure of the gas surrounding the electrodes is reduced to one or two millimeters and a …

A Thesis Presented To The President And The Faculty Of Marquette University For The Degree Of Bachelor Of Science In Civil Engineering And Bachelor Of Science In Electrical Engineering, Anthony B. Czachurski, Benjamin D. Ratke, Joseph G. Casey, William H. Stephan

Bachelors’ Theses

In the work covered by this thesis it is desired to examine an undeveloped water power for the purpose of producing electrical energy as a commercial comodity. Experience has taught that it is best to ascertain first where the product will find its market, and to follow up a satisfactory showing at that end by determining the power capacity of the source, the feasibility of harnessing the same, and the cost of accomplishing this. This program would be adopted in any commercial enterprise to insure a reliable conclusion, and will be followed as closely as possible in the work covered …

Energy Loss In Commercial Condensers, Walter Roland Allen

Electrical and Computer Engineering ETDs

The investigation of the energy loss in condensers is one which electricians and experimenters have long carried on. Their efforts have been restricted chiefly to alternating currents. Many methods have been proposed and used with varying success. The losses in condensers are due to dielectric hysteresis and leakage. That the dielectric of a condenser becomes heated when an alternating current is applied to terminals has long been known. A condenser which has been charged does not lose its entire charge when it is discharged, part of it remaining as a residual charge. Kleiner used the thermo-couple embedded in the dielectric …

Electrolysis Mitigation Of The Underground Telephone Cable Plant Of The City Of Green Bay, Wisconsin, William J. O'Connor

Bachelors’ Theses

Prior to the fall of 1915, the Wisconsin public Service Company of Green Bay operated an electric street railway with an uninsulated negative rail return in the city of Green Bay, the track network with its relation to the underground cable sheaths of the Wisconsin Telephone Company as shown on the General Condition Map.
