Coals of Chile
From Introduction: "The purpose of this investigation was to determine whether the coal from beds mined in the Schwager and Lota mines will produce metallurgical coke suitable for use in the blast furnaces at the proposed steel plant at Conception, and whether the quality of the lower-rank coals from other areas in Chile, especially those in Magallanes, where the large coal reserves of Chile appear to exist; can be improved by processing."

An Index of Shale-Oil Patents
From Introduction: "Work on this project was begun early in 1944; and the results with respect to shale oil are reported in this Bulletin. Since this bulletin is only an index to this large repository of ideas relating to the the treatment of shale oil, the material is presented in the form of short notices describing the subject material of each patent, which consist of an abridgment of the patent (if British or Australian) or a typical claim in the case of the United States or foreign patents."

Preliminary Results of Natural Icing of an Axial-Flow Turbojet Engine
Memorandum presenting a flight investigation in natural icing conditions to determine the effect of ice formations on the performance of an axial-flow turbojet engine. Tail-pipe temperature increased from 761 to 1065 degrees Fahrenheit and the jet thrust decreased from 1234 to 910 pounds during a period of 45 minutes in icing. No general conclusions can be reached from the data because the icing condition was relatively light.

Effects of Ice Formations on Airplane Performance in Level Cruising Flight
"A flight investigation in natural icing conditions was conducted by the NACA to determine the effect of ice accretion on airplane performance. The maximum loss in propeller efficiency encountered due to ice formation on the propeller blades was 19 percent. During 87 percent of the propeller icing encounters, losses of 10 percent or less were observed" (p. 1).

Icing and De-Icing of a Propeller with Internal Electric Blade Heaters
"An investigation has been made in the NACA Cleveland icing research tunnel to determine the de-icing effectiveness of an experimental configuration of an Internal electric propeller-blade heater. Two atmospheric Icing conditions and two propeller operating conditions were Investigated in experiments with unheated blades and with heat applied to the blades both continuously and cyclically. Data are presented to show the effect of propeller speed, ambient air temperature and liquid-water concentration, and the duration of the heat-on and cycle times on the power requirements and de-icing performance of the blade heaters" (p. 1).
