Annual Report of Research and Technologic Work on Coal: Fiscal Year 1941
Report issued by the U.S. Bureau of Mines discussing the annual report over the research and technology of coal during 1941. As stated in the foreword, "these investigations increase our fund of exact knowledge on the properties and composition of American coals and lead to better methods in mining, preparing, storing, and utilizing coal" (p. 4). This report includes tables, illustrations, photographs, and a map.

The 1350 F stress-rupture properties of two wrought alloys and three cast alloys
From Summary: "These properties compare favorably with those of the strongest similar alloys previously investigated. However, compared with a 60Cr-25Fe-15Mo alloy, the three cobalt-chronium-nickel cast alloys are inferior. A correlation of NACA and OSRD (Project NRC-8) data is presented, showing the variation of rupture strengths with temperature in the range of 1350^o to 2000^o for alloys."
