Standardization Of No-Passing Zone Pavement Markings, Glen Nickolas Hackmann Jan 1948

Standardization Of No-Passing Zone Pavement Markings, Glen Nickolas Hackmann

Professional Degree Theses

"This thesis is a comprehensive treatment of present methods practiced by the various Highway Departments in the United States. It presents in particular current methods used by the State Highway Departments and the Public Roads Administration in marking no-passing zones throughout the country. For a long time it has seemed to the author that such a study was needed by both students and highway engineers. Road-design information of great value has developed over the years and often has been published but never assembled in a single orderly presentation stripped of excessive overlapping"--Preface, page ii.


A Geological Report On South Boulder Canyon And The Mayflower Mine-Renova Areas, B. R. Alto Jan 1948

A Geological Report On South Boulder Canyon And The Mayflower Mine-Renova Areas, B. R. Alto

Bachelors Theses and Reports, 1928 - 1970

The purpose of this report is to serve as a written explanation of the accompanying geologic maps and columnar sec­tion. Each year the senior students in mining and geological engineering at the Montana School of Mines spend two weeks in the field where they learn the fundamentals of geologic mapping and related field studies. An additional week is spent at the school where maps are assembled, prints made, end other work is done in preparation for the writing of the report.


Geology 63: Geological Report Of Senior Field Trip, Thomas L. Wilson Jan 1948

Geology 63: Geological Report Of Senior Field Trip, Thomas L. Wilson

Bachelors Theses and Reports, 1928 - 1970

The field work was conducted in areas adjacent to White­hall, Montana, as has been the custom for the past several years. Instruction in the proper use of the telescopic and open sight alidades, and the Brunton compass for surveying geologic features was given. Advantages of pacing and speed­ometer mapping were pointed out and used.

Properties Of Wire Suitable For The Fabrication Of Wire Cloth, Campbell William Floyd Funk Jan 1948

Properties Of Wire Suitable For The Fabrication Of Wire Cloth, Campbell William Floyd Funk

Masters Theses

"In the highly competative [sic] wire cloth industry, improvement of product quality is of paramount importance. With an eye to the future, the Ludlow Saylor Wire Company of St. Louis decided to embark upon a research program with the hope of improving the quality of their products above already high standards. An industrial research fellowship was instituted at the Missouri School of Mines and Metallurgy at Rolla for graduate research studies of the metallurgical, mechanical and chemical properties of wire as the [sic] pertain to the weaving of industrial wire cloth. Although relatively small quantities of wire are defective, their …


Studies Of Contact Angles On Oxidized Copper Minerals, John Stewart Carr Jan 1948

Studies Of Contact Angles On Oxidized Copper Minerals, John Stewart Carr

Masters Theses

"Effective flotation of an ore is the result of several factors: selection of suitable reagents; the proper combination of reagents, processing conditions of the operation proper such as time intervals involved and the machinery used. To focus the investigation on a specific field it was decided to investigate in some detail the behaviour of the more popular collectors toward oxidized copper minerals. This investigation was carried out chiefly by applying contact-angle measurements as obtained with the various collectors on the basic carbonate and oxide copper minerals. This basic information was desirable before carrying out actual flotation tests. There was little …


An Investigation Of The Reduction Of Rutile Copper Oxide Mixtures With Magnesium, Tryggve Smedsland Jan 1948

An Investigation Of The Reduction Of Rutile Copper Oxide Mixtures With Magnesium, Tryggve Smedsland

Masters Theses

"It is known that the addition of titanium to certain types of brasses and bronzes gives them additional valuable properties. The copper-titanium master alloy which is the natural addition agent for making these brasses can not, however, be used if it has been made aluminothermically. It appears that aluminum in the master alloy makes it useless for the above purpose. It should, therefore, be worth while to determine if it is possible to produce a copper-titanium alloy by some method which eliminates the contamination by aluminum, and which would give a copper-titanium which could be used with advantage as an …


The Design, Construction, And Testing Of A Heat Exchanger For Determining Heat Transfer Coefficients For Liquids In Forced Convection Normal To Banks Of Staggered Tubes, Kenneth Edwin Rudert Jan 1948

The Design, Construction, And Testing Of A Heat Exchanger For Determining Heat Transfer Coefficients For Liquids In Forced Convection Normal To Banks Of Staggered Tubes, Kenneth Edwin Rudert

Masters Theses

"Many studies of heat transmission have been carried out on various kinds of heat exchangers. Film coefficients have been determined and the data correlated by equations. In particular, film coefficients have been obtained for gases in turbulent flow normal to both a single cylinder and banks of staggered tubes. Very little data has been published on liquid film coefficients for flow at right angles, or normal to banks of staggered tubes...It is the purpose of this paper to present the results obtained from tests made on an originally designed heat exchanger built in the laboratory. The exchanger is a non-baffled …


Dust Control In Mining Industry And Some Aspects Of Silicosis, Mathuramuthoo Subramanyam Jan 1948

Dust Control In Mining Industry And Some Aspects Of Silicosis, Mathuramuthoo Subramanyam

Masters Theses

"The deleterious effect on human beings of dust in mine air is well-known. It is the duty of engineers, therefore, to take measures to eliminate it. It is now definitely established that of all the various types of dust encountered in mine air, silica dust is the most harmful. This dust, if inhaled over a period of time, causes the disease, silicosis, which in most countries is compensated for as a physical disability. The prevention of alleviation of this scourge is analyzed in three broad aspects: 1. If the mine air is as clean as outside atmospheric air, silicosis will …

Improving Railroad "Less-Than-Car-Load" Freight By The Use Of Containers And Container Cars, Kenneth Walter Schoeneberg Jan 1948

Improving Railroad "Less-Than-Car-Load" Freight By The Use Of Containers And Container Cars, Kenneth Walter Schoeneberg

Masters Theses

"Less-than-car-load (L.C.L.) freight has been and is becoming more of an acute problem with the railroads of this country. They are rapidly losing this vital and important function of their transportation service. Following, is a brief history of the railroads along with a discussion of their present day problems dealing with less-than-car-load freight service. It is believed, by the author, that a system of developing and using containers and container cars along with a pick up and delivery service will solve these problems the railroads now experience. If this method of freight transport would be adopted by the railroads, not …

Reflectorizing Surfaces For Signs And Markers, L. E. Gregg Jan 1948

Reflectorizing Surfaces For Signs And Markers, L. E. Gregg

Kentucky Transportation Center Research Report

The attached copy of a proposed special specification for reflectorizing surfaces for signs and markers is submitted with the recommendation that this be considered by the specification committee, and furthermore that it be considered tentative. The specification was drawn up at the request of the Division of Maintenance in order that they would have some basis for differentiating materials offered by different vendors when invitations for bids are taken. I am sure that Mr. Palmer and Mr. Ringo consider the matter urgent.


A Study Of The Effect Of Blended Coarse Aggregate On Air Entrained Concrete, S. T. Collier, L. E. Gregg Oct 1947

A Study Of The Effect Of Blended Coarse Aggregate On Air Entrained Concrete, S. T. Collier, L. E. Gregg

Kentucky Transportation Center Research Report

This research with combined coarse aggregates in cement concrete was initiated at the request of the Director of Design as a direct result of the condition study made by the Division of Design in 1945. In the report on this study it was shown that on the basis of averages pertaining to 80 projects with crashed limestone totalling about 395 miles in length, and 70 projects with Ohio River Gravel totalling approximately 410 miles in length, the service record for pavements with the river gravel was far inferior to that of pavements containing limestone coarse aggregate.

Specifically, the summary of …
