Test 107: Hart-Parr 12-24, Nebraska Tractor Test Lab Jan 1924

Test 107: Hart-Parr 12-24, 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 …

The Physiographic History Of Five River Valleys In Northern Ohio, Milton M. Champion Jan 1924

The Physiographic History Of Five River Valleys In Northern Ohio, Milton M. Champion

Honors Papers

The purpose of this paper is to explain as far as possible with the data at hand the origin of the five river systems of the area and the physiographic features of their valleys. First, each of the five river valleys will be taken up in a general way; then particular sections of the valleys will be described in detail after which some of the physiographic features not fully explained in the detailed descriptions of the river valleys will be discussed. Finally summary conclusions will be made.

The Disintegration Of Refractory Brick By Carbon Monoxide, Wilbur J. Darby Jan 1923

The Disintegration Of Refractory Brick By Carbon Monoxide, Wilbur J. Darby

Masters Theses

"In experimental work carried on at East St. Louis, Illinois in 1916 and 1917, with a furnace of commercial size for the electrothermic dry distillation of zinc ores, a difficulty that developed was the destruction of the firebrick lining in certain parts of the large condenser. The condenser was satisfactory in other ways, yielding a large proportion of the zinc as liquid metal, with no blue powder; but in order to obtain a proper length of service from the condenser it became necessary to find and overcome the cause of the disintegration of the lining ... it will be evident …

The Effect Of Sulphur Dioxide Gas On Sweet Potatoes, Cotton, And Sorghum Cane Plants, Milburn Leo Dorris Jan 1922

The Effect Of Sulphur Dioxide Gas On Sweet Potatoes, Cotton, And Sorghum Cane Plants, Milburn Leo Dorris

Bachelors Theses

"The chief allegation made by many of the complainants sic in the vicinity of the zinc smelters is that the emanations from the stacks are detrimental to the yield of the crops, especially Sweet Potatoes and Cotton. They claim that on account of the leaves being burned or bleached, the entire plant is poisoned and weakened and the yield is thereby reduced. It was even claimed by some that the presence of the smoke in the atmosphere around the plant has a weakening effect in that it is cumulative, and, while it does not always visibly show, yet the general …


The Equilibrium Of The Reaction Zn + Co₂ = Zno + Co, Clarence Ware Burkhart Jan 1922

The Equilibrium Of The Reaction Zn + Co₂ = Zno + Co, Clarence Ware Burkhart

Masters Theses

"Many attempts have been made in the last twenty years to smelt zinc ores in the electric furnace. The disadvantages of the present retort process have been discussed so often that they need not be dwelt upon here. The principle ones are, the low thermal efficiency of the retort furnace, low metal recoveries, small smelting units necessary, short life of the retorts and the difficulty of treating impure and low grade ores. Electric smelting offers remedies for most of these difficulties"--Introduction, page 1.


The Action Of Tan Bark In The Manufacture Of White Lead By The Old Dutch Process, Elmer List Jan 1922

The Action Of Tan Bark In The Manufacture Of White Lead By The Old Dutch Process, Elmer List

Masters Theses

"This investigation was undertaken because there is very little definite information in print, regarding the micro-organisms which play such an important part in the Old Dutch Process for manufacturing white lead. The statements concerning this process are very general in character. For instance, one book states, "The first action which goes on is to convert blue lead into basic acetate of lead. This is brought about by the heat of the fermenting tan, causing the evolution of acetic acid from the liquid of the pots." Albert H. Hooker in a little treatise on white lead says: "As it stands now, …
