From Summary: "Pilot-plant studies of the hot-carbonate process are described in this report. The initial work was done in a small pilot plant using inert gas containing carbon dioxide and nitrogen."

From Summary: "To incorporate the role of diffusional resistance in the rate equations it is essential that the solid state of the carbons be better understood; that is, their microporosity, crystallinity, and electronic state of free and oxygen-containing reaction sites. The importance of the solid state to kinetic behavior has been stressed throughout the text."

From Summary and Conclusions: "The apparatus and experimental methods used to measure relative permeability-saturation relationships by the unsteady-state displacement method are described for gas-oil systems. The unique feature of the apparatus-design of the gas-oil separator-is described in detail."

From Introduction: "The material in this paper is about central paths and how bacterial enzymes manipulate and cleave the aromatic ring with the formation of hydroxylated aromatic ring with the formation

From Introduction: "Although the objectives and plans have emerged from studies of the Fischer-Trophsch reaction, the most general purpose has been to conduct fundamental studies on the mechanism of catalytic action. With few exceptions, this report work performed through 1957."

From Introduction: "It is purpose of this publication to describe the development of the electrostatic method of particle separation from the early beginning to the present resurgence of interest. Most of the information for this description has been derived from references, a few of which were not available for thorough review."

From Introduction and Summary: "In the assessments of research objectives after World War II it was brought out that little effort had yet been expended on an understanding of turbulent flames.The present report deals exclusively with a second stage of work which was carried out between November 1954 and August 1959. This summary report includes a few new data, but its chief purpose is to reorient the findings toward a better appreciation of what has been accomplished and what most profitably might be done in the near future."

From Introduction: "This paper describes tests of catalysts for the oxidation of hydrocarbons in a microcatalytic reactor."

Report issued by the U.S. Bureau of Mines discussing mercury deposits and the potential for a mercury mining industry in Alaska. History, geology, occurrences, methods, costs, and uses of mercury is presented. This report includes maps, tables, illustrations, and photographs.

Report issued by the U.S. Bureau of Mines discussing mining and milling conducted in Hyde Park, Vermont. As stated in the introduction, "the report describes all phases of the mining methods for the open-pit operation and milling practices employed at the Vermont Asbestos mines in Lamoille and Orleans counties, Vermont" (p. 1). This report includes maps, tables, illustrations, and photographs.

Report issued by the U.S. Bureau of Mines discussing a materials survey conducted on lead. Physicality, history, geology, uses, and locations of lead is presented. This report includes maps, tables, illustrations, and photographs.

Report issued by the U.S. Bureau of Mines discussing techniques for detecting and studying underground nuclear explosions. As stated in the introduction, this report results from a study of only one part of the contemplated inspection system, specifically the final phases embracing on-site investigations and mine examination techniques" (p. 1). This report includes tables, illustrations, and photographs.
