Inundated Anthracite Reserves: Eastern Middle Field of Pennsylvania
From Scope of Report: "In this report one major unwatering project was developed. Three pools that inundate considerable tonnages of anthracite reserves are close enough together to be unwatered by some centralized system. Three alternative plans were studied to estimate the cost of each."

Investigation of a NACA high-speed strain-gage torquemeter
Report presenting an investigation of a strain-gage torquemeter employing a circuit to minimize effects of contact resistance, which was evaluated under static and dynamic conditions. Effects of temperature, axial stress, slip-ring contact resistance, and speed on the operation of the torquemeter were investigated. Results regarding the torsion-shaft static calibration, axial-stress effects, and dynamic operation are provided.

An Investigation of the Longitudinal Characteristics of the MX-656 Configuration Using Rocket-Propelled Models Preliminary Results at Mach Numbers from 0.65 to 1.25
"A rocket-propelled model of the MX-656 configuration has been flown through the Mach number range from 0.65 to 1.25. An analysis of the response of the model to rapid deflections of the horizontal tail gave information on the lift, drag, longitudinal stability and control, and longitudinal-trim change. The lift-coefficient range covered by the test was from -0.2 to 0,3 throughout most of the Mach number range" (p. 1).

The load distribution due to sideslip on triangular, trapezoidal, and related plan forms in supersonic flow
"Expressions are presented for the load distribution on a representative group of plan forms in sideslip at supersonic speeds. These expressions were obtained by the application of lifting-surface theories based on the linearized equation for compressible flow. Sketches of the load distributions are included" (p. 1).

Magnesite Deposits of Central Ceará, Brazil
From introduction: The purpose of this study was to investigate the quantity and quality of [Central Ceara, Brazil] magnesite, and the writer concludes that this group of deposits constitutes one of the major reserves of high-grade magnesite in the Western Hemisphere. The ore could be used in the production of any commercial grade of magnesia with little or no beneficiation. Soil and alluvial overburden is thin between widespread outcrops, so all the deposits could be mined from open pits.
