Test 349: Case Model D, Nebraska Tractor Test Lab Jan 1940

Test 349: Case Model D, 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 …

Consumption And Uses Of Crude Barite And Its Derivatives, Peter Simonds Jan 1940

Consumption And Uses Of Crude Barite And Its Derivatives, Peter Simonds

Masters Theses

"Barite is a widely distributed mineral composed of barium sulphate - BaSO₄. Its most striking feature is its weight - its specific gravity of 4.5 being about twice that of salt and many other of the colorless, transparent and vitreous minerals of its general appearance. The Mineral is usually found in a state of considerable chemical purity. However, small amounts of strontium and calcium sulphates may isomorphously replace the barium salt. Crystals of barytes are orthorhombic; usually very perfectly developed and have a wide variety of forms. The simplest crystals are rhomb-shaped tables bounded by two faces of a basal …


Electrolytic Reduction Of Galena In Fused Salt, Peter Simonds Jan 1940

Electrolytic Reduction Of Galena In Fused Salt, Peter Simonds

Masters Theses

"A demand has long existed for a method of directly recovering elemental Sulphur, in addition to the Lead, from Galena ore. At the present time, the sulphur of this ore is dissipated in the lead blast furnace as sulphur dioxide fumes. While the fumes are trapped to avoid damage to the vegetation of the surrounding countryside, their concentration is usually too low to make sulphuric acid as a profitable by-product. Thus, contrary to some speculation, the sulphuric acid produces under the circumstances is usually not a true by-product in the money-making sense of the term in many cases, but a …


The Volumetric Determination Of Alumina In Clays And Related Materials, David Ferdinand Boltz Jan 1940

The Volumetric Determination Of Alumina In Clays And Related Materials, David Ferdinand Boltz

Masters Theses

"The primary purpose of this thesis was to develop a direct method for the determination of alumina in certain silicates. The classical gravimetric procedure for the analysis of alumina in clays and related materials has often been regarded as being too lengthy and troublesome, especially when only the percentage of alumina was desired. The correct determination of alumina is undoubtedly one of the most unsatisfactory of the chemical constituents of siliceous materials, and therefore the development of a direct volumetric method for the determination of this constituent was made the main objective of this research, page [1].


An Attempt To Correlate Certain Physical And Chemical Properties Of Various Commercial Animal Glues, Robert C. Andersen Jan 1940

An Attempt To Correlate Certain Physical And Chemical Properties Of Various Commercial Animal Glues, Robert C. Andersen

Bachelors’ Theses

The manufacture and use of glue involves many important industries, and up to recent times we, in America, have lost much by our old "rule of thumb" and traditional methods for testing glues. In recent times much work has been done on a strictly scientific basis to explain the actions of glue from both a colloidal and a physicochemical aspect.

This thesis is concerned in particular with the possibility of coordinating the different properties exhibited by the accepted glue tests so that a definite criterion might be postulated for a high-grade animal glue. This task, however, proved extremely difficult, for …

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: John Deere D 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.
