Essential Factors in the Formation of Producer Gas (open access)

Essential Factors in the Formation of Producer Gas

From Introduction Scope and Purpose of Inquiry: "The Bureau of Mines, to which the testing and analyzing of fuels as carried on by the United States Geographical Survey has been transferred, is continuing producer-gas investigations at the testing station at Pittsburgh, Pa. Results of the gas-producer tests made at the coal-testing plant erected at St.Louis, Mo., and of a study of some of the problems that came up in the tests have been published by Geological Survey. Results of the tests made at Norfolk, Va., and Pittsburgh, Pa. and of further studies of particular problems, will be published by the Bureau of Mines."

Recent Development of the Producer-Gas Power Plant in the United States (open access)

Recent Development of the Producer-Gas Power Plant in the United States

From Introduction: "A summary of the tests made at St. Louis and a resume of the conclusions to be drawn from the tests and from the opinions of gas-producer manufacturers on the status of the gas producer and gas engine was published in a Survey bulletin in 1907. As it is desirable to repeat much of the material that appeared in the former bulletin (now out of print), this presentation may be regarded as a revision of the previous one, although considerable information not previously available for publication has been added."

Coal-Mine Accidents in the United States and Foreign Countries (open access)

Coal-Mine Accidents in the United States and Foreign Countries

From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."

Incidental Problems in Gas-Producer Tests

From Introduction: "In the course of this study many incidental problems of prime importance have demanded consideration. Among them is the determination, under practically constant conditions, of the duration of gas-producer tests necessary to reduce the possible error to minimum. A discussion of this proper length of test period forms the part of this bulletin."

Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples

From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."
