IC 7389 Coal-Preparation Practice in Western Germany

This report is one of a series written by members of the Solid Fuels Mission to Germany describing wartime developments in the mining , preparation, and utilization of coal . The mission was organized early in 1945 under the auspices of the Technical Industrial Intelligence Committee , which cooperated with a counterpart British Committee . Engineers from other allied countries cooperated in some of the investigations . The Solid Fuels Mission operated under the direction of a steering committee headed by Dr. C. J. Potter , deputy solid fuels administrator . The personnel of the mission consisted of H. F. Yancey , in charge , J. W. Buch , Thomas Fraser , L. L. Newman , and L. D. Schmidt , of the Bureau of Mines ; H. H. Lowry , Director of the Coal Research Laboratory , Carnegie Institute of Technology ; H. J. Rose , vice president and director of research , Bituminous Coal Research, Inc .; and F. H. Reed , chief chemist , Illinois Geological Survey . Over 50 reports were written by the members of the Solid Fuels Mission . These and microfilms of supporting data obtained in the course of the investigations are on file at the Bureau of Mines , Washington , D. C. where they are available for public examination . The Office of the Publication Board in the Department of Commerce is prepared to furnish photolith copies , photostats , or microfilm reproductions of all declassified reports . A Bibliography of Scientific and Industrial Reports is issued weekly by the Department of Commerce , Office of the Publication Board , and is sold by the Superintendent of Documents , Government Printing Office , Washington 25 , D. C. , on a subscription basis . An initial payment of 10 dollars will provide for approximately 9 months , and subscribers will be notified when additional remittance is necessary . All subscriptions will begin with volume 1 , No. 1 , unless ordered otherwise . The Bibliography covers all materials and subjects and gives instructions for obtaining the desired items . The reports of the Solid Fuels Mission relate to the following general subjects : Mining methods in the Ruhr district of Germany , with special reference to mechanical cutting and loading equipment , pneumatic packing , and Diesel mine locomotives ; activities of industrial research laboratories supported by the German coal and coke industry ; coal preparation in western Europe ; low-temperature carbonization processes ; metallurgical coke from weakly coking coals ; low- ash electrode carbon from coal ; new developments in the production of metallurgical coke and the utilization of gas and byproducts ; briquetting brown coal and bituminous coal without the use of binders ; recent engineering developments in gas turbines and steam generators , with special reference to use of coal ; German coal-fired heating and cooking stoves; and the commercial extraction of coal with solvents for production of synthetic liquid fuels or chemical products . Numerous reports on the activities of German synthetic - liquid -fuels plants and the plants for the production of synthesis gas from solid fuels are available in the same office as the Solid Fuels Reports . It is planned to publish in this series of Information Circulars the more important reports or combinations of reports prepared by the members of the Solid Fuels Mission . A similar series on synthetic - fuel activities is being prepared .
