Mechanical Vibration Of Vacuum Tubes, Jerry Dale Swearingen

Masters Theses

"Since the beginning of the art of vacuum tube building, vacuum tube engineers have been faced with many mechanical problems as well as electrical problems.

Early mechanical problems were comparatively small because most of the tubes were used in stationary apparatus where little or no vibration was envolved.

As time went on, vacuum tubes were placed in portable equipment and this useage established the need for a tube that was mechanically strong enough to give reliable electrical behavior where the tube was subjected to considerable vibration….

Recently it has been shown that vacuum tubes operating in the instrument cabins of …

Deposition Of Titanium By Gaseous Reaction, Louis John Reitsma Jr.

Masters Theses

"Previous investigations undertaken at the Missouri School of Mines and Metallurgy on the deposition of titanium involved the use of fused salt baths, aqueous solutions, and cementation processes. The fused salt baths produced satisfactory coatings on small metal parts. Some difficulty was encountered however, when the coating of large articles was attempted.

For this reason, it was decided to investigate the possibility of titanium deposition by the reaction of a volatile titanium compound with a metal surface. Two different compounds were proposed for investigation, (1) a lower chloride of titanium and (2) an iodide of titanium. The reaction with the …

0007: Samuel Roy Jenkins Diaries, 1887-1941, Marshall University Special Collections

Guides to Manuscript Collections

This collection consists primarily of the diaries of Samuel Roy Jenkins, written from 1887 until 1941. The early diaries, written between 1887 and 1898, deal with his life as a student at Grafton High School and West Virginia University, and later as a civil engineer in Grafton, West Virginia. The middle group of diaries cover the years from 1906 until 1925; Mr. Jenkins' floral business in Grafton and his increasing financial difficulties are the subjects of many of these entries. In the last group of diaries, written between 1930 and 1941, the entries discuss Mr. Jenkins' return to the engineering …

Technical Report Writing, Civilian Personnel Division, Office Of The Chief Of Engineers, Department Of The Army, Robert Bolin , Depositor

United States Army Corps of Engineers, Omaha District

This is a brief manual intended primarily to instruct junior engineering personnel working on civil works for the Corps of Engineers in the proper procedures for preparing reports. Some of the contents were papers delivered at a conference on the use of English in Corps of Engineers reports.

The manual is complicated by the Corps of Engineer’s roles as a military organization and as an organization managing civil public works projects and public facilities and by the special problem of having to answer inquiries of members of Congress.

Shortly before this guide was issued, the Engineer School had issued a …

Measurement Of Irrigation Water, Eldon M. Stock

Reports

Foreword: Although irrigation has been practiced in Utah for more than one hundred years, irrigation water still is being distributed to farmers with little or not thought about its measurement. A farmer would not think of buying or selling other farm commodities, such as hay, grain, beef cattle, or dairy products, without weighing or accurately measuring them, but at the same time he is often content to accept and pay for the irrigation water received with little or no knowledge as to the actual amount received, or whether or not he is receiving the amount he is entitled to. Measurement …

A Study Of Titanium Diffusion Coatings By X-Ray Fluorescent Methods, Alan Bernard Burgess

Masters Theses

"As the only previous determinations of the chemical composition of the titanium coatings had been analyses of the average composition of the entire coating, the determination of the variation in chemical composition throughout the coating was suggested. From this information, it was proposed that a better insight might be gained as to the extent and mechanism of diffusion in the coatings. It was also hoped to correlate the results with concurrent work being done on the phases present in the titanium coatings. From this correlation, it might be possible to show which phases are responsible for the desirable properties of …

Preparation And Separation Of Metallic Chlorides, Norbert Felix Neumann

Doctoral Dissertations

"The use of chlorine and chlorine compounds as metallurgical reagents has long been known to the metallurgical industry. Recent developments in corrosion resistant metals and alloys as well as new equipment and techniques have led to a revival of chlorine processes. Many of the objections to the use of chlorine in metallurgical operations have been overcome and many are being reconsidered, as evidenced by the new processes in which chlorine and chlorides are the primary reagents. The Betterton process employs chlorine or lead chloride for the dezincing of lead. Ductile zirconium and titanium have been made by reducing their chlorides …

Nanbo₃ - Batio₃ - Basno₃ Ceramic Dielectrics, William Dean Mckee

Doctoral Dissertations

"A. The Problem.

The purpose of this investigation was to form by ceramic processes a number of compositions in the ternary system NaNbO₃ - BaSnO₃ - BaTiO₃, to determine certain dielectric properties of these, to study them by means or x-ray diffraction, and to determine the extent or correlation possible between the compositional variation of dielectric properties and the x-ray results.

Compositions investigated contained 50 mole percent or less BaSnO₃. Materials and methods of forming were chosen with the intent that the final bodies should be pure oxide compositions as represented in the ternary …

Roughness As A Factor In Culvert Hydraulics, Eugene M. West

Kentucky Transportation Center Research Report

In conjunction with the oral discussion of Roughness as a Factor in Culvert Hydraulics, which has been scheduled for the coming meeting of the Research Committee, I have assembled a few notes and diagrams with which you may wish to become familiar. It is intended that this material serve as a guide in a simplified approach to some of the basic considerations in the analysis of culverts, and not to be all inclusive.
