Report discussing analysis of methods, where new methods were created to solve specific problems as it relates to mass spectrometry.

Report issued by the U.S. Bureau of Mines discussing surveys conducted on copper. Physicality, mineral properties, history, geology, production methods, and uses of copper are presented. This report includes maps, tables, illustrations, and photographs.

From Introduction: "The purpose of this bulletin is to present a general review of the subject of flammability, and to supply select experimental data and empirical rules on the flammability characteristics of various families of combustible gases and vapors in the air and other oxidizing atmospheres."

From Introduction: "This bulletin presents results of laboratory experiments performed between 1944 and 1956, which have particularly sought to improve the conversion of coal to liquids in small batch-type high-pressure reactors (autoclaves)."

From Introduction: "The primary purpose of this bulletin is to describe the metallurgical treatment and properties of the alloys as developed in research at the laboratories of the Bureau of Mines at Rolla, Mo., and to present a substantial amount of unpublished data."

Report issued by the Bureau of Mines over mineral characteristics, uses, and problems. Descriptions of common minerals and their uses are presented and discussed. This report includes tables, maps, and illustrations. Index and finding guide starts on page 1113.

From Introduction: "This paper is in the nature of a progress report on the Bureau of Mines' program for arc research, combined with a correlation of information from many other sources. An attempt is made to define the arc, to report on the data accumulated, to review published work, and to advance interpretations. It is hoped thereby to supply new information, to clarify the state of arc knowledge, and to stimulate research in other laboratories."

From Introduction: "This bulletin describes the results of poisoning of fixed beds of reduced, carbided, and nitrided fused iron oxide catalysts and reduced steel turnings by H2S in 1H2 + 1CO synthesis gas in tests in which the temperature (1) was held constant and (2) was increased as required to maintain constant productivity."

Report issued by the Bureau of Mines on investigations of tin-lode deposits in the Seward Peninsula. The properties of the deposits sampled are presented. This report includes tables, maps, and illustrations.

From Abstract: "A brief theoretical introduction of the Debye interference function is given, and an outline is made of the treatment of experimental data so that the experimental interference function can be obtained. This study is part of the investigations of the fundamental structure of coals and cokes by the Federal Bureau of Mines. X-ray diffraction is a very powerful tool in studying structure."
