Applications of auxiliary air injectors to supersonic wind tunnels

Description: Report presenting a discussion of the adverse effects of high compression ratio requirements for supersonic wind tunnels as well as the use of second throats for alleviating those effects. The results indicated that an auxiliary air-injector system can reduce starting and running compression ratios as compared to a conventional wind tunnel with a divergent diffuser.

An Approximate Method of Calculating the Deformations of Wings Having Swept, M or W, ? And Swept-Tip Plan Forms

Description: Report presenting a method of calculating the deformations of wings of uniform thickness having swept M or W, upside down V, and swept-tip plan forms. The theory is modified and applied to more complex wing shapes as well as a simplified wing shape.

The Approximation with Anisotropic Effects for Cylindrical Geometry

Description: The method of spherical harmonic tensors developed Mark for solving the Boltzmann transport equation in isotropic media is herein extended to anisotropic media for cylindrical geometry. A formal solution is given for the case of two concentric cylindrical media, A and B, but no numerical work has yet been done. The following treatment differs from a similar one by the H. K. Ferguson Co. in that the external medium B is assumed to be both a neutron absorber and finite in extent rather than a non… more

The attenuation characteristics of four specially designed mufflers tested on a practical engine setup

Description: Attenuation characteristics of four different resonator mufflers were determined in both cold tests and engine field tests and compared with the theoretical calculations. These mufflers were specifically designed for a helicopter. Engine-exhaust sound pressures, temperatures, and noise levels from the helicopter were measured. The experimental muffler cold tests indicated close a agreement with theory, whereas the engine tests indicated some discrepancies. Test results show the usefulness of th… more

Attritioning of Temple Mountain Ore

Description: Abstract: The results of both dry and wet attritioning of Temple Mountain ore are presented. In order to obtain effective attritioning on this ore, the amphaltite must be removed before attritioning. With the asphaltite present, dry attritioning causes a build-up of asphaltite on the surface of sand grains, with consequent loss of uranium values. In wet attritioning, the asphaltite is not broken down or attritioned, because of its low specific gravity and resilience.

Autoclave Testing of Mechanically Jacketed Thorium Slugs In Water

Description: Water corrosion tests on mechanically jacketed and pinholed thorium slugs show that these slugs fail in a manner similar to that observed for mechanically jacketed and tested uranium slugs. The proposed mechanism for the water corrosion of these jacketed slugs is analogous to the water corrosion mechanism of jacketed uranium slugs presented in the project lecture. A bare thorium slug appeared to be more resistant to corrosion by water than a mechanically jacketed slug during the first half of t… more

An Automatic Count and Control System for a Beta-Ray Spectrometer

Description: From abstract: An electromechanical automatic count and control unit for a beta-ray spectrometer is described. The count control unit provides for constant or time limited recording of data and actuates an automatic stepping system which sweeps a well regulated motor generator power supply over 100 increments of focusing magnet current.

An Automatic Polarograph for the Determination of Uranium in Process Waste Streams

Description: The automatic polarograph is ideally suited for the analysis of waste streams for uranium in the Metal Recovery Process, and with modification, it is applicable to other processes, pilot plants, and even to laboratory set ups. The instrument is simple, dependable, and relatively trouble free in operation. It provides an immediate record of the uranium in the waste and, through better control of the process, lower processing costs.

Average Fission Cross Section U238 for Fission Neutrons

Description: By means of measurements with a double ionization chamber, the average fission cross section of U238 for neutrons from the fission of U235 was determined in terms of v, the average number of neutrons per fission of U235. the number of fission of U238 was measured in one of the ionization chambers while the number of fissions from the fission neutron source of U235 was measured in the other chamber. In the nine runs made to determine the cross section, a variety of different methods was used to … more

Axial-load fatigue tests on notched and unnotched sheet specimens of 61S-T6 aluminum alloy, annealed 347 stainless steel, and heat-treated 403 stainless steel

Description: From Summary: "Axial-load fatigue tests at a stress ratio of zero were performed on notched and unnotched sheet specimens of 61S-T6 aluminum alloy and 347 and 403 stainless steels. Special emphasis was placed on tests at high stress levels which produce failures in small numbers of cycles."

Backmixing in Pulse Columns II, Experimental Values and Effect of Several Variables

Description: Seven runs were made with the system Penn. Ref. Co. "Supersol" (dispersed) water (continuous) to investigate the effects of pulse frequency, amplitude plate spacing, volume flow ratio, and throughput on backmixing, using the technique of continuous injection of a tracer solution into the packed section. Backmixing was found to be surprisingly insensitive to all the above variables over the range studied with the exception of pulse amplitude and continuous phase flow rate, showing greatest depe… more

A Ball Holder for Coating Operations

Description: A device has been designed which will support small spheres and cylinders in a vacuum system during a plating operation. While supporting the object to be plated, the device automatically shifts the position of the supports so that the coating is evenly distributed. This report describes the mechanism by which this motion is achieved.

Battelle Memorial Institute trip report, November 1953

Description: The hot pressing die successfully bonded a composite of Ni plate U and Al. A die for step processing is being fabricated. Cu and Mg additions to the AlSi bath lower the dipping temperature but increase intermetallic formation with ductility loss. Optimum dipping rate for continuous AlSi coatings has been established. Extrusion of Al over a cylindrical core was successful. 7.5% Zr-U is not sensitive to oxygen content under crevice corrosion in boiling demineralized water. A method was developed … more
