An Analysis of the Dissipation of Heat in Conditions of Icing From a Section of the Wing of the C-46 Airplane

Description: From Introduction: "The performance of the heated wing of the C-46 airplane (reference 1), in conditions of icing, has been analyzed. The method of calculating the dissipation of heat, both by convection and by evaporation, from a heated surface exposed to conditions of icing is given in reference 2."

Analytical methods and results

Description: Report detailing the analytical methods and results of a study designed to measure the total alpha particle activity of samples. The method being used was previously in use at Columbia University. The report recognizes potential for grave errors, but makes no effort to minimize the effect of the roughness of the sample.

Application of Conductivity Measurements to a Study of (a) Complex Formation Between F[ Gamma] + and F- and Al+ + + and F- (b) Titration of F- Ion with H + Ion

Description: From introduction: This report describes some preliminary electro-conductometric titrations which were made in order to ascertain whether the method [for selecting the best complexing agent for any problem that may arise] gave interpretable results.

Bonding Strengths of Adhesives at Normal and Low Temperatures

Description: Note presenting a determination of the bonding strengths of two thermosetting adhesives, liquid Cycleweld C-3 and Ardux 1, to several aircraft materials using shear tests made on lap-joint specimens. The specimens were tested at 25 degrees Celsius and at subfreezing temperatures of approximately -40 degrees Celsius. Results regarding the specimens bonded under clamping pressure, specimens bonded after various surface treatments, specimens of metal bonded to plywood, and specimens of aluminum bo… more

Broadway Special, featuring New York's Latest Hit, "The Hasty Heart"

Description: This soldier show contains two copyrighted works—"The Hasty Heart," a three-act by John Patrick; and "Freedom of the Air," a ten-minute sketch by George S. Kaufman—plus several blackouts and sketches and three simple musical production numbers "restricted to Army and Navy use exclusively." Production numbers each include a libretto and a piano-vocal score. A survey form is included to measure the success and appropriateness of the materials provided.

Calculations of Economy of 18-Cylinder Radial Aircraft Engine With Exhaust-Gas Turbine Geared to the Crankshaft

Description: Calculations based on dynamometer test-stand data obtained on an 18-cylinder radial engine were made to determine the improvement in fuel consumption that can be obtained at various altitudes by gearing an exhaust-gas turbine to the engine crankshaft in order to increase the engine-shaft work.

Casting Uranium Bars as a Substitute for the Extrusion Process

Description: The usual method of producing uranium slugs for the reaction pile is to cast the metal into billets which are extruded into rod about 1.45 inches in diameter. Slugs are then machined from this to the final size of 1.359 inches in diameter by 8 inches long. Extrusion is done in the gamma range at a temperature of about 1000 C, where the metal is soft enough to be extruded at relatively low pressures. This operation is difficult and expensive and the product is not entirely satisfactory. The bill… more

Charts of Pressure, Density, and Temperature Changes at an Abrupt Increase in Cross-Sectional Area of Flow of Compressible Air

Description: "Equations have been derived for the change in the quantities that define the thermodynamic state of air - pressure, density, and temperature - at an abrupt increase in cross-sectional area of flow of compressible air. Results calculated from these equations are given in a table and are plotted as curves showing the variation of the calculated qualities with the area expansion ratio in terms of the initial Mach number as parameter. Only the subsonic region of flow is considered" (p. 1).

Clinton Engineer Works Division of Chemical Research and Development Monthly Report: May/June 1945

Description: A report about the ongoing work regarding density. Attention was directed toward the accurate ascertainment of the T losses involved in a process in which the partially dried peroxide is transferred from the sintered glass funnels to the gold boats, and in which the calcination is male from TO4 to T3OE under nitrogen in the green salt reactors.

Colorimetric Analysis for Cadmium - Diphenylthiocarbazone (Dithizone) Method

Description: Abstract: The well known colorimetric method for determining cadmium by means of dithizone has been reinvestigated and found applicable to solutions containing interfering ions much as are found in the plant. Copper, however, must be removed prior to using this analytical procedure.
