This report describes progress regarding construction of a small pilot plant and a five-step process involving hydrochloric-sulfuric acid treatment and acetone extraction.

This report describes progress in testing nonaqueous extractive methods for leaching Western ores of uranium and vanadium

From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.

Technical report. The extent of the Wigner effect in graphite at any point in a pile is sensitive to the local structural situation. It is greater near a slug. These control experiments give information on changes in graphite to be expected in selected places in the pile.

This report discusses the production of ceramic ware through the process of slip-casting. The report separately describes the processes of creating zirconia ware, beryllia ware, alundum ware, thoria ware, and specially shaped ceramic ware.

Report presenting chordwise pressure distributions measured over the left wing of a Convair XF-92A delta-wing airplane at low lift to determine the effect of Mach number on the wing characteristics at transonic speeds. The critical Mach number of the basic wing was 0.83 for an airplane normal-force coefficient at 0.09. The spanwise load distributions were roughly triangular in shape.

Report presenting a program to investigate the aerodynamic characteristics of a family of delta wings with a blunt double-wedge section in the hypersonic tunnel at Mach number 6.9. The wings varied at semiapex angle and were tested over a range of angles of attack and Reynolds numbers. Results regarding lift and drag characteristics, center of pressure and moment coefficient, Schlieren photographs, and surface film flow studies are presented.

From Summary: "Hydrodynamic characteristics have been determined for a 1/13.33-scale jet-powered dynamic model of the Martin XP6M-1 flying boat with the forebody modified so as to increase the depth of step and the angle between the forebody and afterbody keels. Longitudinal stability during takeoff and landing in smooth water and resistance of the complete model in smooth water and in waves are presented."

"A solution is presented for the coupled modes and frequencies of swept wings mounted on a fuselage. The energy method is used in conjunction with power series to obtain the characteristic equations for both symmetrical and asymmetrical vibration. A numerical example which is susceptible to exact solution is presented, and the results for the exact solution and the solution presented in this paper show excellent agreement" (p. 1).

Report presenting an analytical investigation to determine primarily the reduction in cooling-air requirement and the increase in effective gas temperature for the same quantity of cooling air resulting from the use of an insert in the cooling-air passage of a hollow air-cooled turbine blade.

Report presenting an investigation in the high speed tunnel to determine the aerodynamic loading characteristics of a 45 degree sweptback wing of aspect ratio 4, taper ratio 0.6, and an NACA 65A006 airfoil section. The effects of fences and leading-edge notches over a range of Mach numbers and angles of attack were also explored. Results regarding chordwise load distributions and lateral center of pressure are provided.

Report presenting the effects of deflecting full-span, constant-chord, leading-edge flaps with round or sharp leading edges on the lift, drag, and pitching-moment characteristics of a model of an interceptor-type aircraft at supersonic and subsonic speeds.

Memorandum presenting an investigation of the effects of orientation by multi-axial stretching on properties of various plastic glazing materials. The materials studied were Lucite HC-222, Plexiglass 55, Gafite, and resin C. Some of the tests conducted included dimensional stability at elevated temperatures, surface abrasion, standard tensile tests, and stress-solvent crazing tests using ethylene dichloride.
