Final Report on Recovery of Thorium and Uranium From Monazite Sand : Volume 1

Description: Report describing a method for recovery of high yields of thorium and uranium from monazite sand concentrates. Monazite is decomposed into hydrous metal oxides, which are dissolved in an acid. The solution is then separated into a precipitate, which seperates from thorium and uranium. An alternate separation method is evaluated.

Estimated Manufacturing Costs for the Recovery of Thorium and Uranium from Monazite Sand

Description: Abstract: "Costs have been estimated for the production of uranium and pure thorium from monasite concentrates by a process involving (1) reaction of monasite with caustic soda, (2) dissolution of the hydrous oxides in hydrochloric acid, (3) separation from the bulk of the rare earths by hydroxide precipitation of thorium and uranium, and (4) purification by solvent extraction."

Low-Powered Induction Heater for Testing Use.

Description: Certain laboratory processes require low-powered radio-frequency heating with fine continuous control. A lightweight low-powered induction heater which is capable of delivering about 20 watts of power into a load 12 feet from the heater with fair efficiency was developed to meet this need.

Experimental Investigation of Various Wing-Mounted External Stores on a Wing-Fuselage Combination Having a Sweptback Wing of Inverse Taper Ratio

Description: Report presenting an investigation in the high speed tunnel to determine the effects of several wing-mounted external-store configurations on the aerodynamic characteristics of a model of a swept wing-fuselage combination for a range of Mach numbers. Some of the configurations explored included inboard underwing installations and wing-tip installations. Results regarding lift-drag ratios, drag characteristics, lift-curve slope, and pitching-moment characteristics are provided.

Initial flight investigation of a twin engine supersonic ram jet

Description: From Summary: "A flight investigation was made of a supersonic twin-ram-jet test vehicle using short-flame-length burners. The test demonstrated a maximum acceleration of 3.6g and a maximum flight Mach number of 3.02. Data were obtained over a Mach number range from about 1.9 to 3.0, an altitude range from 1,800 to 40,900 feet, and a fuel-air-ratio range from 0.012 to 0.065."

Some Features of Artificially Thickened Fully Developed Turbulent Boundary Layers with Zero Pressure Gradient

Description: Report gives an account of an investigation conducted to determine the feasibility of artificially thickening a turbulent boundary layer on a flat plate. A description is given of several methods used to thicken artificially the boundary layer. It is shown that it is possible to do substantial thickening and obtain a fully developed turbulent boundary layer, which is free from any distortions introduced by the thickening process, and, as such, is a suitable medium for fundamental research.

Some Theoretical Problems Concerning Paramagnetic Substances at Low Temperature

Description: Technical report discussing six problems in paramagnetic substances at low temperatures: 1) The Kramers degeneracy; 2) The quenching of orbital motion; 3) Curie constants of CuSO4∙5H2O; 4) Super exchange in CuSO4∙5H2O; 5) The specific heat of CuSO4∙5H2O; and 6) Nuclear interactions of paramagnetic ions. The discussion of these problems brings to light the general principles involved and the general principles can then help understanding of many low temperature phenomena in the paramagnetic sal… more
