The Coke Industry of the United States as Related to the Foundry

Description: From Introduction: "The present bulletin, published by the Bureau of Mines because of the analyzing and testing of fuels have been transferred from the Geographical Survey to the Bureau of Mines, briefly reviews the status of the coke industry, some features of practice in the use of coke in the foundry, the probable happenings of a cupola heat, and the reasons for modifying charging practice so that a particular coke can be used to best advantage."

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 for publication has been added."

Briquetting Tests at the United States Fuel-Testing Plant, Norfolk, Virginia, 1907-8

Description: From Briquetting Tests: "The briquetting work undertaken at Norfolk had these specific objects: 1. To determine what percent of pitch or other binder was necessary to make a satisfactory briquet out of the coals tested. 2. To investigate the relative merits of different binders. 3. To provide briquets for comparative combustion tests of run-of-mine coal and the same coal briquetted."

Comparative Tests of Run-of-Mine and Briquetted Coal on Locomotives

Description: From Introduction: "For purpose of procuring data that could be using in estimating the value of the briquetting process as applied to American fuels, the United States Geological Survey, in cooperation with other interests, began in 1904, at the Louisiana Purchase Exposition, certain experiments involving the production and use of bituminous-coal briquets."

Comparative Tests of Run-of-Mine and Briquetted Coal on the Torpedo Boat Biddle

Description: From Introduction: "With the particular equipment used in the tests both coal and briquets were far from smokeless; consequently the data of this bulletin are applicable only by analogy to parallel operation with a coal more nearly smokeless, but nevertheless applicable with much reliability. It was the original intention to make a set of preliminary steaming tests alongside a dock (which tests furnish material for this bulletin) an to finish with a set of running tests at sea; but the running tests were never made. for lack of time and men."

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 at Norfolk, Va., and Pittsburgh, Pa. and of further studies of particular problems, will be published by the Bureau of Mines."

Incidental Problems in Gas-Producer Tests

Description: 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."

Tests of Run-of-Mine and Briquetted Coal in a Locomotive Boiler

Description: From Object of Tests: "The primary object of the tests was to study the relative performances of the two types of briquets and of the coal, with reference to efficiency, tendency to smoke, and the ease with which steam could be kept up, when each of the three varieties of fuel was burned at several rates of combustion. Many secondary objects were in mind, the data concerning which are discussed under "Effect of varying rates of combustion," pages 20-27."

Comparative Fuel Values of Gasoline and Denatured Alcohol in Internal-Combustion Engines

Description: From Introduction: "Under the terms of the act establishing the Bureau of Mines, this bureau was authorized to carry on the work of testing and analyzing fuels which had been conducted by the technologic branch of the United States Geological Survey. Therefore, the first investigations of the liquid mineral fuels logically embraced a careful series of comparative tests of gasoline and denatured alcohol in engines. The report is published by the Bureau of Mines because of the transfer of the fuel-testing investigations to this bureau."

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

Description: 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."

Shorter Contributions to General Geology, 1929

Description: From introduction: This report describes the deposits of analcite in the Green River formation, to compare them with other similar deposits, and to present them with other similar deposits, and to present the observations and inferences that led him to explain them as alteration products of volcanic ash that fell into an ancient saline lake. The report also records the occurrence of several thin beds of sepiolite, or meerschaum, in the Green River formation and presents new data on the molds of saline minerals of the Green River formation whose determination affects directly the interpretation of the analcite and sepiolite deposits.

Tin Deposits of Irish Creek, Virginia

Description: From abstract: Cassiterite was discovered along Irish Creek in the Blue Ridge in the northern part of Rockbridge County, Va., in 1846, but active prospecting and development work were not begun until 1884. The production has been small, probably less than 1,000 tons of ore, and has come chiefly from workings on Panther Run, a small tributary near the headwaters of Irish Creek.

Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria

Description: From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."
