Test 819: Farmall 504 (Gasoline), Nebraska Tractor Test Lab

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT GENERAL CONDITIONS East tractor is a production model equipped for common usage. Power consuming accessories can be disconnected only when it is convenient for the operator to do so in practice. Additional weight can be added as ballast if the manufacturer regularly supplies it for sale. The static tire loads and the inflation pressures muse conform to recommendations in the Tire Standards published by the Society of Automotive Engineers. PREPARATION FOR PERFORMANCE RUNS The engine crank case is drained and refilled with a measured amount of new oil conforming to specifications in the operator’s manual. The …

A Study Of The Dissolution Of Zr-O Alloys In Hydrofluoric Acid, Wayne Gilbert Custead

Doctoral Dissertations

"The purpose of this investigation was to ascertain and explain, if possible, the effect of oxygen in the metal on the kinetics and electrochemistry of the reaction of zirconium in hydrofluoric acid solutions. This entailed the determination of the effect of oxygen on the dissolution rates, activation energies, dissolution potentials, and difference effect for zirconium in hydrofluoric acid and hydrofluoric-hydrochloric acid mixtures.

The alpha-phase solid solutions of oxygen and zirconium were synthesized by the powder-metallurgy technique. Both the alloy analysis and dissolution rates were obtained by the gas evolution method according to the reaction:

ZrO_x + 4HF → ZrF …

An Investigation Of The Deformation Textures Of Cobalt, Roy Carl Wilcox

Doctoral Dissertations

"Deformation textures of various cobalt structures as a result of cold rolling together with some annealing textures were studied. The textures of cobalt were determined using a modification of the Schulz-Decker Geiger counter technique. Pole figures of the (1011), (0001) and (1010) planes were constructed. Also, a study of the microhardness of cobalt was made.

Microhardness tests were performed on various cobalt structures, in both the cold rolled and unworked conditions. The microhardness was found to vary with the source of the cobalt, the crystal orientation, and the amount of deformation and twinning. Deformation lines about the hardness impressions diffused …

Statistical Analysis Of Fracture Stresses Of Triaxial Porcelain Bodies, Robert E. Moore

Doctoral Dissertations

"Triaxial porcelain bodies containing various forms of silica, quartz, cristobalite and fused silica, were strength tested in bending. Significance tests were employed to discern real differences in the strength sample statistics caused by the various forms of silica. Firings were performed at three temperature levels. The differences in strength sample statistics were correlated to the microstructures of these silica porcelains.

A triaxial alumina porcelain body was employed as a model brittle solid for a study of the effect of flaw density on mean fracture stress. The flaws were introduced in the form of large diameter (d̄ = 115 microns) rounded …

Lattice Parameters, Densities And Imperfections In Indium And Indium-Cadmium Alloys Rich In Indium, Paluri Bhimeswara Rao

Doctoral Dissertations

"An investigation of perfection of the structure of the indium-cadmium system was suggested by the interesting properties of indium and its cadmium alloys. The lattice of indium, though tetragonal, may be considered as distorted cubic, its axial ratio being 1.0767 at 20°C. Furthermore earlier studies have revealed a transformation of the tetragonal structure to cubic in the presence of cadmium.

To determine the perfection or soundness of the indium and indium-cadmium alloys rich in indium, pure indium (99.999 per cent purity) and eight samples of the indium-cadmium alloys ranging in composition from 2.977 to 10.015 per cent by weight of …

Fm 55-8, Transportation Intelligence, 1961, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

In 1961, American military intelligence was decentralized. The Army was responsible for all intelligence concerning foreign armed forces. Within the Army, the technical services – Transportation Corps, Signal Corps, Ordnance Corps, etc. – were responsible for intelligence concerning analogous organization in foreign organizations. The Transportation Corps was responsible for intelligence concerning foreign transportation equipment and services. Since there was no centralized American military intelligence organization, the Transportation Corps was tasked with supplying intelligence concerning foreign road and rail networks and waterways as well as ports and landing beaches and airfields.

This manual defines transportation intelligence and prescribes Army doctrine concerning …

A Machine-Laid Surmountable Bituminous Concrete Median, Robert L. Florence

Kentucky Transportation Center Research Report

On August 28, 1961, personnel of the Research Division were requested to observe a demonstration of a newly developed Etnyre Median Paver. The demonstration was given at the Lehman-Roberts Company plant in Lexington, and was arranged primarily for the benefit of the paving contractor working on Euclid Avenue in Lexington. The paving contract called for the construction of a surmountable bituminous concrete median which, to our understanding, is the first instance for construction of that type to be machine-laid. Some doubts arose during the demonstration as to the ability of the machine to hold alignment and to give adequate compaction. …

An Investigation Of Indeterminate Structures Stressed Beyond The Proportional Limit, Jack B. Joyce

Civil Engineering ETDs

In the structural field the methods of designing have been geared to the development of materials...In a more current appraisal we see steel and concrete being updated still further. Pre-stressed concrete is a common sight in present day construction work and, to a lesser extent, the educated eye sees rigid frames designed to ultimate load criteria. Here again are cases where materials are studied and found to possess characteristics that are adaptable to advance methods. The key to all such improvements is still the realization and utilization of material properties.

Water Requirements For Waterfowl Areas Near The Great Salt Lake Parts V-Vi, J. E. Christainsen, Ming Chang Tsai, D. K. Kaushik, J. B. Law, J. W. Teeter

Reports

This report reviews activities on this project since the Progress Report, Part IV, June 1961.

The summer of 1961 has been one of the driest on record for Ogden Bay and Howard Slough Refuge. The extreme shortage of irrigation water has resulted in very little flow in the Howard Slough which originates from return flow. The available water from the Weber River for the Ogden Bay Refuge was also the lowest on record. The scarcity of water at these two refuges has resulted in increased salinity.

Most of the routine work on the project during the summer was done by …

Portland Cement Stabilization Of Western Kentucky Gravels, Robert C. Deen

Kentucky Transportation Center Research Report

It has been known for some time that some Western Kentucky bank gravels perform rather poorly as base or shoulder material. In the fall of 1956, the Division of Research participated in the experimental design and evaluation of a group of ten rural highway base stabilization projects. Two of these projects, one in Ballard County and one in Marshall County involved the stabilization of Western Kentucky bank gravels with a bituminous material; AE-200, a mixing-type emulsion, was used.

The performance of these bitumirlous-stabilized gravels has not been entirely satisfactory. Even though little tendency was noted for the asphalt to bleed …
