An Acoustical Investigation Of Parker Hall Auditorium At The School Of Mines And Metallurgy Of The University Of Missouri, John Douglas Martin

Masters Theses

"The auditorium in Parker Hall on the Missouri School of Mines campus has been noted locally for its poor auditory characteristics. At times in the past corrective treatment has been considered but no detailed or experimental data were gathered. In September of 1934 the writer was detailed under an FERA project to study the room and to determine the best method of correction"--Introduction, page 1.

A General Survey Of Traffic Accidents In Knoxville, Tennessee, For A Period Of Six Months, William Stewart Harkness

Masters Theses

[From the Introduction]

This thesis is a study of traffic accidents in the city of Knoxville, Tennessee. Traffic accidents in any city of approximately the same size as Knoxville present many problems. An effort has been made to present as many phases of such accidents as possible.

A study of this type in Knoxville has its peculiar difficulties. No consistent reports of accidents were made before January 1, 1933, when a plan was inaugurated calling for a report of every accident to be turned in as soon as possible to the Safety Bureau. However, reports were not required …

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 …

Investigations Concerning Bentonite Deposits Near Ramsay, Montana, Anton A. Anjel, John F. Sullivan

Bachelors Theses and Reports, 1928 - 1970

The purpose of Part I of this report is to determine the origin of the bentonite deposits, also to locate them with reference to section corners in the vicinity and to determine their extent.

The field work for this report was done in the fall of 1933 and during the spring of 1934. The roads, geologic contacts, and culture in general were mapped with the use of an open sight alidade and plane table. Distances were determined on the roads by the speedometer on the automo­bile; the detailed survey in the immediate vicinity of the deposits was done with use …

Geology And Ore Deposits Of The Butte-Highland Gold Mine., Stockton Veazey Jr.

Bachelors Theses and Reports, 1928 - 1970

The Butte-Highland mine is situated at the head of Basin Creek, in the Highland mining district, Silver Bow County, about 14 miles south of Butte. The tunnel portal and present surface plant are at an elevation of about 7350 feet above sea level, facing westward across the head of Basin Creek valley. The "ghost" mining town of Highland lies a mile to the east, near the forks of Fish Creek. Access to the mine is obtained at present from Beaudine's siding, 12 miles west. The property may also be reached, with difficulty, over poor roads from Limekiln hill, or from …

Supergene Enrichment Of Silver Ores With Special Reference To Those From Neihart, Montana., Thomas Walker Page

Bachelors Theses and Reports, 1928 - 1970

In the development of a technique it was necessary to learn the fundamentals of ore microscopy as applied to the various minerals of silver, which included the use of reflected polarized light, etch reactions, micro­chemical analysis, and sight recognition of mineral. In addition it was necessary to become familiar with the accepted criteria of sequence, replacement, and other textural phenomena.

Preliminary Floatation Tests On The Beneficiation Of A Low-Grade Montana Bituminous Coal., William Packwood Given

Bachelors Theses and Reports, 1928 - 1970

Coal is an aggregation of vegetal matter with varying small amounts of mineral and animal matter which have been so changed by the processes of sedimentation, decay and metamorphism that it has become a dense, dark, combustible substance. It occurs in beds varying in thickness from one foot or less to over 300 feet. The horizontal extent of a bed is sometimes continuous over an area as large as the State of Montana.

Auriferous Tertiary Gravels Near Rocker, In Silver Bow County, Montana, William C. Mclaughlin

Bachelors Theses and Reports, 1928 - 1970

Between the villages of Rocker and Silver Bow, in south­western Montana, are found an interesting group of placers. Gold occurs in Tertiary gravel beds that are interstratified with beds of rhyolitic volcanic ash. With the aid of a plane table and open-sight alidade, a small portion of the lake-bed area near Rocker was mapped; all distances were paced, but numerous checks assure a fairly accurate map.

The Age-Hardening Of Duralumin, Allison Richard Dyer

Bachelors Theses and Reports, 1928 - 1970

The development of wrought alloys of aluminum to which high strength and ductility can be imparted by heat treatment began with the work of Wilm and Claesser in Germany, 1905­-1911. During this time an alloy was developed which was later commercially produced in that country under the tradename of duralumin. The need for strong, light alloys for aircraft during the World War greatly hastened the development of duralumin.

The Effect Of Impurities On The Electrodeposition Of Zinc From Zinc Sulfate Solution Containing Antimony., Emmitt L. Klebba

Bachelors Theses and Reports, 1928 - 1970

It has been proven by research and years of experience, that before electrolytic zinc is possible, the electrolyte, as zinc sulfate solution must be prepared as pure as is economical. In other words, the ideal electrolyte must only be a solution of one metal - zinc. Every other metal and carbon must be excluded if good recovery and a firm deposit is to be obtained.

Ammoniacal Sulphate Leach Of Ananconda Zinc Calcine Recovery Of The Zinc By Electrolysis., Authur Jewett Bovee Jr.

Bachelors Theses and Reports, 1928 - 1970

Zinc is produced from ores by two general methods, distillation and electrolysis.

The general principles involved in the electrolytic zinc process of today were known as far back as 1880. Difficulties encountered in purifying the solution for electrolysis and lack of suitable mechanical apparatus were the main reasons that such a long time elapsed before the process was used to produce zinc in commercial quantities.

Precipitation Of Gold, Silver, And Copper From Cyanide Solutions On Activated Charcoal., Rayworth Francis Howe

Bachelors Theses and Reports, 1928 - 1970

Charcoal has been known for a considerable length of time to have the property of recovering gold, silver, and copper from cyanide solutions of these metals. Quantita­tive data that may shed light on the mechanism of the re­moval of these metals is very limited except that char­coal in a form known as activated has the power to abstract gold and silver in considerable quantities from the above solutions.

Alloys Of Lead And Tellurium, Ettore A. Peretti

Bachelors Theses and Reports, 1928 - 1970

Prior to the last few years little practical use was made of the element tellurium, which is obtained from gold and silver tellurides and from the slimes of electro­lytic copper refineries. Lately, however, more study has been made of its properties when alloyed with other metals. It was the purpose of this thesis to study the effects of the addition of tellurium to lead, particularly in small amounts.
