Test 226: Caterpiller Model 22, Nebraska Tractor Test Lab Jan 1934

Test 226: Caterpiller Model 22, 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 …

EXPLANATION OF TEST REPORT: John Deere A

TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear.

This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.

The Calcite Veins Of The Livingston Formation, John Moore Conrow May 1933

The Calcite Veins Of The Livingston Formation, John Moore Conrow

Bachelors Theses and Reports, 1928 - 1970

An interesting group of calcite veins occur near Livingston Montana in a zone about eight miles wide and forty miles long in the edge of the Plains region of Montana in front of the Main ranges. The zone extends from the Boulder River south of Big Timber, through Springdale and Hunters Hot Springs, to Potter's Basin just north of Wilsall in Park County. The group of veins is particularly interesting because they cut relatively flat lying strata, suggest a structural relation­ship to one another, and they are nearly pure calcite.

The present investigation was to determine the position of the …

A Study Of The Composition Of Zinc Complex Cyanide Solutions By The Conductometric Method, Robert James Woody

Bachelors Theses and Reports, 1928 - 1970

As the method or analysis used up to the present time has failed to give quantitative results in determining the composition of zinc cyanide baths, conductometric methods were adopted in this study. Supplementary tests were also carried out in this investigation.

Some Problems In The Construction Of Artificial And Natural Gas Pipe Lines, Waring Mikell Jan 1933

Some Problems In The Construction Of Artificial And Natural Gas Pipe Lines, Waring Mikell

Professional Degree Theses

"In 900 A.D. the Chinese piped natural gas through bamboo tubes and used it for lighting, and about 1830 artificial gas was carried by three inch wooden pipes in a town in New England. Today there are many thousands of miles of steel pipe bringing gas from Western fields to eastern cities, and many more miles of steel and cast iron pipe for the distribution of artificial and natural gas in the majority of the towns and cities in the United States. This paper will deal with the construction of acetylene welded steel pipe lines, and some of the problems …


The Replacement Of Calcium Carbonate With Calcium Chloride And Calcium Fluoride In A Whiteware Body, Charles Richard Rosenbaum Jan 1933

The Replacement Of Calcium Carbonate With Calcium Chloride And Calcium Fluoride In A Whiteware Body, Charles Richard Rosenbaum

Bachelors Theses

"In the steel industry it is a common metallurgical practice to add fluospar sic (CaF₂), to a slag to render it more fluid. Ladoo states that the fluospar sic , thus added, forms eutechtics with the silica, alumina, calcium and barium sulfates, rendering them more fusible. The fluospar sic does not decompose, but forms solutions or eutechtics with other substances in the slag. He further states that calcium chloride (CaCl₂) has been used for this purpose but is apparently not as active, necessitating larger quantities per charge. It is also probably more expensive. Calcium carbonate (CaCO₃) is commonly used as …


The Effect Of Reheating Certain Fire Brick On Pyrometric Cone Equivalents, Francis J. Louney Jan 1933

The Effect Of Reheating Certain Fire Brick On Pyrometric Cone Equivalents, Francis J. Louney

Bachelors Theses

"In a recent survey of the refractories field, especially with respect to the softening point of fire brick, it was suggested to the author that the possibility of reheating certain fire brick, according to the specifications given by the American Society for Testing Materials, might produce a difference in pyrometric cone equivalent from that of the original or unreheated sample. At present, there is considerable lack of knowledge regarding the problem, as evidenced by the utter lack of literature on the softening point resulting from the reheating of fire brick"--Introduction, leaf 1.

A Plant Efficiency Survey And Experimental Plant Results Obtained At The Sioux Falls Sewage Treatment Plant, Sioux Falls, S.D., Lowell A. Yost, Hans Jepson Jan 1933

A Plant Efficiency Survey And Experimental Plant Results Obtained At The Sioux Falls Sewage Treatment Plant, Sioux Falls, S.D., Lowell A. Yost, Hans Jepson

Electronic Theses and Dissertations

"Sioux Falls, the largest city in South Dakota is situated on a bend in the Sioux River. The flow of this river ranges from a recorded minimum flow or 9 to a maximum flood flow of 500 cu. ft. per second. As originally designed and built the sewage system emptied into the river at three main outlets. In 1910 the City had a population of approximately 14000 people, and during the next decade its population practically doubled. During this period of growth there was added to the industries of the City a large meat packing plant which has been steadily …

The Relation Between The Mean Molecular Weight And The Absolute Viscosity Of Lubricating Oils, John Isler Moore Jan 1933

The Relation Between The Mean Molecular Weight And The Absolute Viscosity Of Lubricating Oils, John Isler Moore

Masters Theses

"Of all the properties required of a good lubricant the most important is that of the viscosity at the temperature of its use. Most lubricants consist of oils blended or compounded together in such a way as to produce an oil of a desired viscosity, falling in the special group of viscosities expressed by the Society of Automotive Engineers in their tabulations.

There have been several methods developed to enable the refiner to blend quickly and efficiently although Bell stated that the methods were largely that of trial and error. Herschel formed a chart for blending by the logarithmic rule …

Factors Affecting The Performance Of Kerosene Cook Stoves, Edna B. Snyder Nov 1932

Factors Affecting The Performance Of Kerosene Cook Stoves, Edna B. Snyder

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this investigation was to learn the effect of constructional details of the burner and the framework on the performance of kerosene stoves. Six stoves were used, four of the long-chimney type and two of the short-chimney type. Of the long-chimney burners, three were from the same manufacturer; the fourth was similar in appearance, but differed in performance. Of the short chimneys one burner used a wick, the other a lighting ring. The effect of: (1) draft variations and constructional details and (2) the framework on the heating time and thermal efficiency of stoves was studied.


Problems Encountered In The Development Of An Airport, A. H. Armstrong Jun 1932

Problems Encountered In The Development Of An Airport, A. H. Armstrong

Theses

The progress of a nation and. its transportation facilities have always advanced hand in hand.

Just as it has always beerthe Civil Engineer's problem to develop facilities for other means of transportation, such as roads, harbors, and. railroad terminals, so is it his problem today to build airports.

In presenting the problems encountered in the development of an airport, the writer has considered the airport's place in city and regional planning, as well as the part it plays in air transportation.

An expression of thanks is given to Mr. Wm. S. La Londe, Jr., professor in Civil Engineering at the …
