Stream Reconnaissance for Nutrients and Other Water-Quality Parameters, Greater Pittsburgh Region, Pennsylvania

Description: Abstract: Eighty-five stream sites in and near the six-county Greater Pittsburgh Region were sampled in mid-June 1971 and again in mid-October 1972. Concentrations of inorganic nitrogen, organic carbon, or phosphorus were high enough to indicate potential problems at about a quarter of the sampling sites. Temperature, dissolved oxygen, and pH values indicated a generally favorable capacity for recovery from degradation, although a number of streams east of the Allegheny and Monongahela Rivers a… more

Stone Dusting or Rock Dusting to Prevent Coal-Dust Explosions, as Practiced in Great Britain and France

Description: From Introduction: "Coal dust as an agent of widespread explosions had been under suspicion, and watering to allay the dust was recommended by some mining engineers but the watering of coal-mine dust was adopted in comparatively few mines of the United States and Great Britain, and had not been introduced widely in any country except Germany. Rock dusting, another method of preventing explosions of coal dust, was early tested with success by the Bureau of Mines in its first gallery at Pittsburg… more

Sources of Limestone, Gypsum, and Anhydrite for Dusting Coal Mines to Prevent Explosions

Description: From Preface: "The writer began testing the rock-dusting method for the Bureau of Mines at the Pittsburgh gallery in 1909, and later continued such testing in the bureau's experimental mine, with favorable results. Beginning in 1911 the bureau issued reports recommending rock dusting as alternative to watering."

Essential Factors in the Formation of Producer Gas

Description: 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 … more

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

Description: 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… more

Apparatus and Methods for the Sampling and Analysis of Furnace Gases

Description: From Introduction: "It is the purpose of this paper to describe some apparatus and methods which have proved satisfactory to those engaged in the chemical work of the investigations mentioned. While these methods and apparatus have been designed more particularly with regard to analysis of furnace gases, their use is by no means limited to that purpose."

Explosion Tests of Pittsburgh Coal Dust in the Experimental Mine, 1925 to 1932, Inclusive

Description: From Introduction and Summary: "The first of these was Bulletin 353, dealing with the tests of rock-dust barriers; the second is the present paper, which reports tests made to determine the effect on the explosibility of Pittsburgh coal dust of altering conditions under which the tests were made; the third, dealing with tests of dust prepared from approximately 20 coals taken from beds in mines in different parts of the United States, will follow after the completion of testing in progress at t… more

Physical Testing of Explosives at the Bureau of Mines Explosives Experiment Station, Bruceton, Pennsylvania

Description: From Introduction: "The methods of making the physical tests of explosives recorded here are based upon the results of more than 20 years of experience of the staff of the explosives division of the Bureau of Mines at the Pittsburgh testing station and at its successor, the Explosives Experiment Station, Bruceton, Pa. The methods are described in unusual detail to permit repetition that will duplicate, as nearly as possible, the precise manner in which they have been performed in the past and t… more
