Test 376: Massey-Harris Model 81-R, Nebraska Tractor Test Lab Jan 1941

Test 376: Massey-Harris Model 81-R, 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 …

Dry Pressing Refractory Insulating Brick, Frank Clarence Steimke Jan 1941

Dry Pressing Refractory Insulating Brick, Frank Clarence Steimke

Bachelors Theses

"The expensive process of grinding the insulating brick and the slow production methods of hand forming led to the possibilities of dry pressing the brick. The use of the dry press would increase production, give greater uniformity to the brick and materially reduce grinding if not eliminating it entirely. Since present day combustives were either impractical or else impossible to use, some new material must be found. Three materials presented themselves, napthalene, sulfur, and petroleum coke. The former for its low melting temperature and the latter two for their complete volatility at high temperatures and low if not negligible resiliency. …


Firing Behavior Of Missouri Plastic Fire Clay, William E. Crockett Jan 1941

Firing Behavior Of Missouri Plastic Fire Clay, William E. Crockett

Bachelors Theses

"There are two districts in Missouri in which plastic fire clay occurs. The oldest and least significant of these deposits is the "Cheltenham", in the St. Louis area. The most prominent area in which plastic fire clay occurs is generally termed the "east central" district. Included in this district are Calloway, Montgomery, Audrain, Warren, Boone, Monroe, Pike and Lincoln Counties. The clay as tested in this report occurs in Boone County, near Columbia. A plastic fire clay does not have as high a P.C.E. (pyrometric cone equivalent) as the ordinary flint and semi-flint clays, but its high plasticity warrants its …

The Age-Hardening Of Aluminum With Mgzn2, Sidney E. Worthen May 1940

The Age-Hardening Of Aluminum With Mgzn2, Sidney E. Worthen

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to investigate the age-hardening of aluminum with magnesium and zinc in such proportions as to conform to the compound MgZn2.

Because of a lack of time and proper equipment, the only property investigated was the hardness as indicated by the Rockwell Superficial Hardness Tester.


The Measurement Of Current Efficiency In Zinc Sulphate Electrolytes Containing Antimony And Cobalt By Hydrogen Evolution, Arthur R. Hard May 1940

The Measurement Of Current Efficiency In Zinc Sulphate Electrolytes Containing Antimony And Cobalt By Hydrogen Evolution, Arthur R. Hard

Bachelors Theses and Reports, 1928 - 1970

The measurement of current efficiency by hydrogen evolution is based on the assumption that the portion of the current which deposits no zinc will release hydrogen. This assumption is correct for solutions containing no impurities electropositive to zinc.


The Testing And Concentration Of A Low Grade Copper-Nickel Ore., Laurence T. Eck May 1940

The Testing And Concentration Of A Low Grade Copper-Nickel Ore., Laurence T. Eck

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to investigate the possi­bility of concentrating a low grade copper-nickel ore, to determine the most effective method of concentration, and to attempt to draw some conclusions to determine whether or not the concentrates produced would be of sufficient high grade to make the recovery of nickel and copper a profit­able enterprise.


Electrolysis Of Molten Mixtures Of Galena And Lead Chloride., Donald Q. Cole May 1940

Electrolysis Of Molten Mixtures Of Galena And Lead Chloride., Donald Q. Cole

Bachelors Theses and Reports, 1928 - 1970

Electrolysis of molten mixtures of lead chloride and galena was carried out under various conditions of temperature, time, composition, and current densities; without a diaphram, and with various diaphrams. Continuous runs, with necessary additions of lead sulfide and lead chloride to maintain a melt of the proper composition, were attempted on a small scale.

Adjusting Planters And Listers For Sorghums, L. W. Hurlbut

Nebraska Agricultural Experiment Station: Historical Circulars

It is the purpose of this circular to present data and suggestions that will aid the farmer in attaining greater success in the planting of sorghum. It has been prepared primarily for the machine operator; and, although it is not a complete discussion of planters and listers, it contains highly practical suggestions regarding the adjustment of the corn planter and lister for sorghum seed.


Engineering In Traffic Safety In Utah, Donald T. Hunter May 1940

Engineering In Traffic Safety In Utah, Donald T. Hunter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Traffic safety involves accident-free movement of physical entities. It includes all means of transportation and is a function of mobility, an important variable affecting directly the mortality rate and increase of accidents. All transportation groups have coincidentally with or without increase of mobility been attempting to reduce accidents. Those notably succeeding are the shipping, railroad, and airline interests. The operating motor vehicle and pedestrian groups have failed conspicuously.

The early means of attaining a better degree of traffic safety in the motor vehicle and pedestrian groups were based on opinions, and though rational, were incomplete because of the dynamic and …

Essentials Of Rock Drill Design, Lister Merriken Cummings Jan 1940

Essentials Of Rock Drill Design, Lister Merriken Cummings

Professional Degree Theses

"The earliest history of the rock drill is obscure and only fragmentary evidence concerning it is recorded in the Patent Office. However, no other tool has played a more important part in mining and excavating work. There have been two general classes of pneumatic rock drills -- the reciprocating, or piston machine, and the hammer drill. Fowler played an important part in the early development of piston machines, and the first hammer drill was made in about 1895 by a man named Brothers"--History, page 1.


The Application Of Fluid Level Measurements To Oil Wells In Kansas, Charles Calvert Rodd Jan 1940

The Application Of Fluid Level Measurements To Oil Wells In Kansas, Charles Calvert Rodd

Professional Degree Theses

"The mechanics of determining fluid levels and a knowledge of the depth-to-fluid in a well are matters of general interest. To the oil-producer, however, such information is of value only as it may affect the operation of a well or reservoir"--Uses of Fluid-Level Measurements, page 9.


The Clark National Forest Of Missouri, Walter A. Werner Jan 1940

The Clark National Forest Of Missouri, Walter A. Werner

Professional Degree Theses

"The question might logically arise as to the appropriateness of a thesis with a forestry title being submitted for an engineering degree. The writer has been connected with the United States Forest Service for the past four years in an advisory capacity on staff of the Forest Supervisor of the Clark National Forest, during which time he has found that the engineers and construction men have performed a major function in the development of the forest.

As the initial development consisting of lineal surveys, construction of roads and telephone lines, erection of fire lookout towers, planning and erection of ranger …


Red Glazes, Sidney Austin Peer Jan 1940

Red Glazes, Sidney Austin Peer

Bachelors Theses

"Red glazes are extremely difficult to produce on pottery except at relatively low temperatures, or under conditions which can only be regarded as largely accidental. For many years ceramists have demanded a red glaze maturing at cone 4. To produce this glaze, much time and research is required...The object of this study was to produce a commercial red glaze at cone 4 from different oxides in a base glaze of white lead and silica"--Scope of Investigation, pages 1, 7.
