Buried Valley of the Susquehanna River: Anthracite Region of Pennsylvania

Description: Report issued by the U.S. Bureau of Mines regarding a buried valley area (a deposit of clay, sand, and gravel) around the Susquehanna River in the anthracite region of Pennsylvania, near the city of Wilkes-Barre. According the the introduction, "The purpose of this report is to furnish data on the buried valley of the Susquehanna River that will be useful in solving the anthracite mine-water problem" and "This report (a) discusses the physical characteristics and the influence of the buried va… more

Carbonizing Properties: Pocahontas Number 6, Davy Sewell, and Fire Creek Coals from West Virginia and Upper and Lower Kittanning and Upper and Lower Freeport Coals from Pennsylvania

Description: From Forward: "The value of this survey of the carbonizing properties of American coals by a standard method lies in the comparability of the results on different coals. It must recognized that no standard laboratory method of carbonization, even on a large unit, can yield results that exactly duplicate those obtained in ovens and retorts. The commercial results vary with the type of oven or retort. Allowance must be made for such differences in interpreting the BM-AGA test results in terms of … more

Characterization of Tar Acids from Coal-Hydrogenation Oils

Description: From Introduction: "The purpose of this investigation was to separate and identify as many of the principal phenolic compounds produced by the mild hydrogenation of Pittsburgh-bed (Bruceton) coal as possible and to determine with the greatest possible accuracy the proportions in which they are present."

Comparison of BM-AGA and Slot-Oven Experimental Methods of Carbonization, with Results for Eleven Coals

Description: From Introduction and Summary: "However, with the completion and satisfactory performance of an experimental vertical slot oven of 500-pound capacity at the University of Illinois Geological Survey Laboratory, the opportunity to directly compare BM-AGA coke with coke made by two-sided heating became available and the necessary test apparatus was installed. This report compares the results obtained by the two methods."

The Counting Efficiency of Counter Tubes with Aluminum, Copper and Gold Cathodes for X-Rays in the Range 5 Kev to 60 Kev

Description: The author's measurement using counting tubes were performed with an X-ray beam, produced by an X-ray tube. The X-ray beam impinges on only a very small part of the counting tube. In this work the counting efficiency of counting tubes with A1-Cu- and Au-cathodes is determined for X-radiation in the range 5 Kev to 60 Kev.

The Creep of Zirconium in Water

Description: Introduction:"Very little is known about the mechanical properties of zirconium and, in view of this the Atomic Energy Commission requested Sylvania to evaluate the creep characteristics of this metal at various temperatures. Tests at room temperature (25 C) and at 200 C have been completed, the tests having been conducted in air. The data obtained from these tests form the basis of this report. Future tests will be conducted in an atmosphere of water at the desired testing temperature."

The Extrusion of Beryllium

Description: Abstract: "A method for the extrusion of beryllium into rods and tubing has been developed. The operation is carried out between 1500 and 1900 F and the billet is clad in a layer of soft iron to prevent contact between it and the die steals. Extruded beryllium has much more strength and ductility than cast metal due to the crystal refinement which occurs as a result of the fabrication operation."

Heats of Formation of Some Aqueous Ions of Americium

Description: Abstract: "The heats of formation of Pr-(+3) (aq.) and La-(+3) (aq.) have been measured in 1.5M HCl at 25 C. to be -165.9 +/- 0.9 kcal/mol and -167.0 +/- 0.7 kcal/mol, respectively. The heat of formation of Am-(+3) (aq.) under the same conditions was found to be -161.3 +/- 1.4 kcal/mol. The latter value made it possible to calculate the heat of formation of Am-(+4) (aq.) as -112.2 kcal/mol. It was impossible at this time to determine the heats of formation of AmO2+ (aq.) and AmO2++ (aq.)."

Inundated Anthracite Reserves: Eastern Middle Field of Pennsylvania

Description: From Scope of Report: "In this report one major unwatering project was developed. Three pools that inundate considerable tonnages of anthracite reserves are close enough together to be unwatered by some centralized system. Three alternative plans were studied to estimate the cost of each."
