Test 130: Mccormick-Deering 15-30, Nebraska Tractor Test Lab Jan 1926

Test 130: Mccormick-Deering 15-30, Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.

All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.

Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …


Recovery Of Carbonate Copper Ore By Means Of Flotation At The Kennecott Copper Corporation Plant, Kennecott, Alaska, George Leo Richert Jan 1926

Recovery Of Carbonate Copper Ore By Means Of Flotation At The Kennecott Copper Corporation Plant, Kennecott, Alaska, George Leo Richert

Professional Degree Theses

"The Kennecott Copper Corporation mines and the adjoining Mother Lode Coalition Co. mine, which the Kennecott Copper Corporation controls and operates as an integral part of their Kennecott, Alaska camp, are situated in the Nizina Mining District, 196 miles inland from Cordova, Alaska, the tide-water shipping point. The first claims were discovered in 1900, and these later became the property of the Kennecott Copper Corporation. The Kennecott holdings consist of 111 mineral claims and the Mother Lode Coalition Co. has 73 claims"--Introduction, page 4.

The Fissure System Of El Potosi Mine Of El Potosi Mining Company, Santa Eulalia, Chihuahua, Mexico, Carl E. Millikan Jan 1925

The Fissure System Of El Potosi Mine Of El Potosi Mining Company, Santa Eulalia, Chihuahua, Mexico, Carl E. Millikan

Professional Degree Theses

"The fissures traversing the country were the means of mineralizing the district. The North-South system of fissures have been determined to be pre-mineral, hence the most important. Their intersections with cross fissures are the regions of orebodies, and the intersections have always produced ore of mineable quantity. Especially important are the intersections of fissures in the "favorable" (fossiliferous) limestone beds. The favorable limestones are easily recognizable and can be traced thru all parts of the district because of their distinctiveness and the uniformity of the structure of the region"--Summary, page 19.

The Properties Of The Fire Clays Used For The Manufacture Of Zinc Retorts, Adolph Harmon Kuechler Jan 1925

The Properties Of The Fire Clays Used For The Manufacture Of Zinc Retorts, Adolph Harmon Kuechler

Masters Theses

"The ultimate object of this refractories investigation is to develop a body for zinc retorts, or changes in the method of their manufacture, that will result in better retorts than the ones now in use. In doing this, the question of permissible cost must, at all times, be kept in mind. The immediate object of the present phase of this investigation, of which this thesis covers only a part, is to determine the physical and chemical properties of the refractories (fire clays, grogs, bodies, etc.) now used for the manufacture of zinc retorts. This will be a basis for later …

The Reduction Of Zinc Oxide By Carbon, George August Zeller Jan 1924

The Reduction Of Zinc Oxide By Carbon, George August Zeller

Masters Theses

"In spite of the fact that the reduction of zinc oxide by carbon is the fundamental reaction upon which the pyrometallurgy of zinc is based, there is a decided lack of accurate knowledge concerning the mechanism of the reaction, the temperature at which it begins, and the effect of various factors upon the rate at which it takes place"--Introduction, page 1.


On Plain Carbon Steel, Walter Edward Remmers Jan 1924

On Plain Carbon Steel, Walter Edward Remmers

Masters Theses

"In 1921, an investigation was carried on by Messrs. Howe, Foley and Winlock, under the auspices of the National Research Council, the results of which were published under the title of - "Influence of Temperature, Time and Rate of Cooling on Physical Properties of Carbon Steel," by the American Institute of Mining and Metallurgical Engineers, February, 1923. These results showed that all physical properties of a 0.34 C. percent steel are improved by increasing the rate of cooling from temperatures above the critical range up to a certain rapidity beyond which, there is a gain in strength at the expense …


The Solubilities Of Certain Inorganic Salts In Anhydrous Normal Alcohols, William Orval Keeling Jan 1924

The Solubilities Of Certain Inorganic Salts In Anhydrous Normal Alcohols, William Orval Keeling

Masters Theses

"An examination of the literature shows that extensive studies have been made of the solubilities of inorganic salts in aqueous, normal alcohols, but that little has been done in determining the solubilities in anhydrous alcohols. Northing was found of a systematic study of the solubilities of NaCl, KCl, NaN0₃ and KNO₃ in the lower alcohols over a fairly wide range of temperature. The author has made a study of the solubilities of the above mentioned salts in lower anhydrous normal alcohols at the temperatures 20°C, 25°C, 30°C and 40°C"--Introduction, page 1.

Accident Prevention In Cement Plants, Edward Rees Abbott Jan 1924

Accident Prevention In Cement Plants, Edward Rees Abbott

Bachelors Theses

"The cement industry as a whole took up accident prevention work along with the pioneers. With the organization of the Portland Cement Association, a Bureau of Accident Prevention was formed. This Accident Prevention Bureau, by sending out literature, holding competitions, collecting and tabulating results of accidents collected from every cement manufacturer and affiliating with National Safety Council as the Cement Section, has made rapid strides each year, until today it is doubtful if any other branch of manufacturers can show more improvement in accident records than the cement industry. In spite of their marked improvements each year, there were 47 …
