Structure and Propagation of Turbulent Bunsen Flames

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."

Briquetting Tests of Lignite at Pittsburgh, Pennsylvania, 1908-9 : With a Chapter on Sulphite-Pitch Binder

From Results of Briquetting Tests: "The results of the briquetting investigations conducted by the Government are expected to prove of considerable value, not only to the Government itself as the owner of extensive lignite deposits and largest single purchaser of fuel, but also to the people living in the the regions where lignite is found. The problem assumes still larger proportions when one realizes that the development of manufacturing industries in those regions depends upon the ability to obtain a cheap and satisfactory fuel. Although the results presented in this bulletin are not conclusive, they warrant the continuation of the investigators as soon as funds can be available for the purpose."

National Mine-Rescue and First-Aid Conference: Pittsburgh, Pennsylvania, September 23-26, 1912

From Introduction: "It this report endeavor has been made to eliminate all unnecessary remarks; but in order that those who hold diverging views regarding the subjects discussed may have before them the arguments that led the conferees to vote for the 36 resolutions adopted, the discussion had in the committees and in open session is published practically in full. Moreover, for the information of those mining officials, operators, and surgeons who are unfamiliar with approved methods of first-aid training and training with breathing apparatus and safety devices and methods of rescue, it seems equally desirable that the few opening addresses and closing remarks made it general session should be published as an expression of the reasons for such work and for the conference."

Oil and Gas Wells through Workable Coal Beds: Papers and Discussions

From Preface: "In carrying out such a policy with reference to the subject under consideration, the Bureau of Mines invited the State geologists, mine inspectors, and a number of coal operators and oil and gas well drillers from the States interested to meet representatives of the Bureau of Mines in Pittsburgh, Pa., for a discussion of the subject during February 7 and February 8, 1913. This adjourned meeting of the conference will be held at an early date and its report will be printed in a later edition of this bulletin, with such additional suggestions as may be received by the Bureau of Mines. The bureau will be glad, therefore, to receive at the earliest practicable date any additional suggestions or any additional information throwing light on the matters discussed in this bulletin."

A Primer on Explosives for Coal Miners

From Introduction: "Much of the information in this primer has been obtained from experiments conducted by the technologic branch of the United Sates Geological Survey at the mining experiment station at Pittsburgh, Pa. These investigations have shown the recent development of a new type of short-flame explosives, which can be used with greater safety than black powder in mines where there is dangerous gas or inflammable dust, because the flame from the explosion of black powder lasts from 2,500 to 3,500 times as long does the flame from these newer explosives and is therefore more likely to ignite the gas or dust in such mines."

Combustion of Coal and Design of Furnaces

From Purpose and scope of Investigations: "The combustion investigations of bureau are carried on in two parts. One part is the study of the process of combustion in the fuel bed as affected by the rate of supplying air through the fuel bed, by the character of the fuel as regards structure and composition, by the thickness of fuel bed, by the method of feeding the coal and the air and by the method of heating the coal. The second part of the investigation is the study of the process of combustion of the gases and other combustible rising from the fuel bed in the combustion space, after a sufficient quantity of air has been added. The results of the study are given in this report."
