Stability Investigation Of Bituminous Pavements, Kentucky Highway Materials Research Laboratory Mar 1945

Stability Investigation Of Bituminous Pavements, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

This stability investigation was started by the Bituminous Division of the Highway Materials Research Laboratory, Lexington, Kentucky during the month of October, 1944, and was completed the first of March 1945. The purpose of this investigation was to develop information on the design and control of asphalt pavements. The data presented may be used to compare mixes made from commercial aggregates with mixes containing local aggregates. It is believed that sufficient amount of reliable data is presented in this report to enable the design engineer to use the Marshall stability equipment and testing procedure to select the best available aggregate …

The Reaction Of Ethylcellulose With Fatty Acid And Its Application To The Varnish Industry : Ii. Ethylcellulose In Pencil Lacquers., Albert L. Kimmel Feb 1945

The Reaction Of Ethylcellulose With Fatty Acid And Its Application To The Varnish Industry : Ii. Ethylcellulose In Pencil Lacquers., Albert L. Kimmel

Electronic Theses and Dissertations

Ethylcellulose was refluxed with Stearic, Oleic, Linseed Fatty acids, and a neutral Mineral Oil in the presence of a solvent. The products recovered were analyzed to determine if any possible reaction had taken place. Conditions for the reaction were carried out so that the temperatures obtained could be in the near range of varnish cooking, that is between 375 and 500°C. The I solvents used were diethylbenzene, boiling point 180oC and tetralin, boiling point 208oC. In each case approximate stoichiometric proportions of the fatty acids and ethylcellulose were used. These were refluxed to a sensible minimum viscosity of solution. The …

The Examination And Treatment Of Industrial Magnesium Foundry Wastes, Oden Cass Garst Jan 1945

The Examination And Treatment Of Industrial Magnesium Foundry Wastes, Oden Cass Garst

Professional Degree Theses

"The principle forms of magnesium foundry wastes not recovered by industry are fine dusts, such as, sawdust, rotary filings and grindings, and the melting- and refining-pot drosses. The Bureau of Mines has studied waste generation and has developed processes for the treatment of dresses for the recovery of secondary ingot metal and has also developed processes for the mechanical beneficiation of fine dusts. The studies on fine dusts were continued until suitable melting methods for the recovery of ingot metal, approximately meeting the applicable specifications, were developed...Recommendations are made for improved melting methods for magnesium sawdust that increase greatly the …


A Technique For Making Torsion Balance Surveys Of Inundated Areas, Karl Frederick Hasselmann Jan 1945

A Technique For Making Torsion Balance Surveys Of Inundated Areas, Karl Frederick Hasselmann

Professional Degree Theses

"The need for a technique for making torsion balance surveys of inundated areas was brought to the writer's attention during the years of 1927 to 1933, while employed by The Sinclair Exploration Company to prospect for oil in Austria, Hungary and North and Northwest Germany. At that time, the company was using ten torsion balances, supplementing the work with magnetometer surveys and refraction seismograph detail. During part of this period an elementary and relatively insensitive gravimeter was used. Some reflection seismograph work was also done during the last year of operations. During the course of surveying in North and Northwest …


Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering Jan 1945

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

I. SCOPE OF THIS REPORT In the Thirty-eighth Progress Report a series of 118 tests was reported on web crippling under concentrated loads. These 118 tests which included 17 representative tests of the Twenty-fifth Progress Report were carried out for web crippling by loads on the span, by simple end reactions, by end reactions with additional loads on top flange, and by reactions of continuous supports with similar additional loads. Two formulas were developed from the entire series of tests which represented, for the two cases (loads on span, and reactions), all test results with satisfactory accuracy. However, only 8 …


A Comparative Analysis Of Some Recent Mining Practices In The Tri- State Mining District, James Francis Alexander Taylor Jan 1945

A Comparative Analysis Of Some Recent Mining Practices In The Tri- State Mining District, James Francis Alexander Taylor

Masters Theses

"The Tri-State District, encompassing contiguous corner portions of Southwest Missouri, Southeast Kansas, and Northeast Oklahoma, has been, for many years, the leading zinc producer of the United States. However, rising labor costs and decreasing grade of ore reserves have meant that many of the mines gradually have become marginal in the economic character of their operations. In an attempt to counteract these adverse effects, steps were taken to attain lower cost mining methods, and mechanization has been introduced over a period of years. Further, the research program of the Eagle-Picher Company, the leading producer of the district, has been accelerated …

A Study Of The Separation Of Feldspar From Missouri Granite, Vernon Louis Kasten Jan 1945

A Study Of The Separation Of Feldspar From Missouri Granite, Vernon Louis Kasten

Masters Theses

"The greatest use of feldspar is as a flux in the Ceramic Industry where it is used in the manufacture of abrasives, floor tile, terra cotta, china, and earthenware of all types. It is also used in the manufacture of glass and enamels, and much is used as grinding medium in powdered form because it is softer than the common abrasive, quartz...Missouri Granites are composed of feldspar, quartz, mica, and other materials, which may or may not occur in all the samples. It is the purpose of this investigation to attempt a separation of the feldspar from these other components …

The Solubility Of Zinc Ethyl Xanthate In Water, Thomas M. Mckenzie Oct 1944

The Solubility Of Zinc Ethyl Xanthate In Water, Thomas M. Mckenzie

Bachelors Theses and Reports, 1928 - 1970

A determination of the solubility of zinc ethyl xanthate was attempted by measuring the refractive index of a saturated solution of that salt. The small increment in refractive index effected by adding zinc ethyl xanthate to water in saturation quantities rendered measurements difficult and of dubious accuracy.

The Study Of The Drying Of Buna S., George W. Williams, Richard L. Harvin Oct 1944

The Study Of The Drying Of Buna S., George W. Williams, Richard L. Harvin

Electronic Theses and Dissertations

A study of the drying of Buna-S in crumb form (designated as GR-S) is presented in which investigations of vacuum and air drying are made. The drying characteristics are presented and the effect of drying on the quality is evaluated. Vacuum drying is investigated using a shelf and a rotary type unit. The individual effects of temperature, vacuum, thickness of crumb layer, and size of crumb particles are studied. Data are correlated by means of drying rate curves. Comparisons of the effects of the variables are made using these curves. Air drying is studied by the use of a shelf …


The Development Of Ethyl Cellulose Lacquers For Automotive Use : An Ethyl Cellulose Lacquer For Coating Plastics., Robert Carlton Krueger Oct 1944

The Development Of Ethyl Cellulose Lacquers For Automotive Use : An Ethyl Cellulose Lacquer For Coating Plastics., Robert Carlton Krueger

Electronic Theses and Dissertations

There have been developed various colored ethyl cellulose lacquers that compare favorably with standard nitrocellulose lacquers in physical tests. Ultra violet light caused rather pronounced darkening of the lighter colors such as white and light yellow, probably because of the use of high amounts of phenolic resin. Also because of the presence of relatively large amounts of phenolic resin, the cost was somewhat higher than a comparable nitrocellulose lacquer. Suggestions for further work and improvement are included. An ethyl cellulose lacquer has also been developed to be applied by spray or brush to ethyl cellulose plastics with a minimum amount …
