Test 277: Mccormick-Deering Tractractor Model Td-35, Nebraska Tractor Test Lab Jan 1937

Test 277: Mccormick-Deering Tractractor Model Td-35, 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 …

Pyrochemical Changes In Missouri Halloysite, Frank Joseph Zvanut Jan 1937

Pyrochemical Changes In Missouri Halloysite, Frank Joseph Zvanut

Doctoral Dissertations

"For centuries it has been known that the application of heat to a clay or a clay body produces changes that make it an entirely different substance from the original raw clay. Ever since the earliest civilizations produced crude building brick by baking formed clay bodies in the sun's rays, mankind has been speculating on the nature of the changes that convert soft, friable, plastic clays into hard, strong, non-plastic, rock-like masses. It has been only within the last two decades, however, that progress has been made in the solution of problems dealing with the resultant products in fired clay …


The Preparation And Properties Of Diphenylthiocarbazone, Floyd C. Mcintire Jan 1937

The Preparation And Properties Of Diphenylthiocarbazone, Floyd C. Mcintire

Theses and Dissertations

At present the chemical literature offers no method for the preparation of diphenylthiocarbazone, or dithizone, sufficiently detailed to guide the average laboratory technician in an economical and successful preparation of this compound. The high price of dithizone and the limited number of dispensers of it emphasize the need of such a method. The original research reported in this thesis was done primarily in an attempt to formulate a satisfactory detailed method for the preparation of dithizone. The suggestions of Emil Fischer were followed and an attampt was made to improve his outline and to note the possible errors so that …


A Study Of Methods For The Recovery Of Silver, Bromine, Iodine, And Sodium Thiosulfate From Used Photographic Fixing Baths, Leroy Agustave Bay Jan 1937

A Study Of Methods For The Recovery Of Silver, Bromine, Iodine, And Sodium Thiosulfate From Used Photographic Fixing Baths, Leroy Agustave Bay

Masters Theses

"Sodium thiosulfate was one of the pioneer reagents used in photography, and is still the most important reagent used in photographic fixing. The solubility of the silver halides in an excess of sodium thiosulfate makes it important as a reagent for removing the undeveloped silver halides from the film. The life of a fixing bath is controlled by the halogen content. As the ratio of halogens to sodium thiosulfate is increased, the time required for fixing is also increased until the ratio reaches such a point that fogging of the film results. Most of the solutions are discarded long before …


Wood Occurring In The Ginkgo And Associated Petrified Forest (No. 1-The Gingko), George F. Beck Dec 1936

Wood Occurring In The Ginkgo And Associated Petrified Forest (No. 1-The Gingko), George F. Beck

All Faculty Scholarship for the College of the Sciences

The most interesting single fossil tree, but at the same time the most difficult to determine in the Ginkgo Petrified Forest (Washington), is the tree after which this unusual petrified forest takes its name. The ginkgo is not only the world's oldest and most remarkable living tree, but it has long been regarded as holding the most striking fossil record of any living thing, plant or animal.


Grinding Thin Sections For Determining Petrified Woods, George F. Beck Dec 1936

Grinding Thin Sections For Determining Petrified Woods, George F. Beck

All Faculty Scholarship for the College of the Sciences

The collector and student of petrified woods cannot long be satisfied to merely place these colorful and interesting specimens in the cabinet with the mere label, "petrified wood." Frequently determining the types of wood which once thrived in a given area is of importance to give a clue to climatic conditions of past geological ages. The collector should at least be qualified to recognize the more common woods and distinguish one family of trees from another.

Spruce In The Western Miocene, George F. Beck Nov 1936

Spruce In The Western Miocene, George F. Beck

All Faculty Scholarship for the College of the Sciences

One of the real surprises in store for us as we began to section specimens of petrified wood from the Vantage and certain other horizons in Central Washington, was the prevalence of a spruce type hardly hinted at in the leaf lists as published for the various sediments of Yakima time (upper miocene?).
