Additional Extraction and Ion Exchange Studies of Temple Mountain District Ores

Description: Uranium extraction of 95% has been obtained from samples of Temple Mountain ore by a cyclic test procedure in which the new feed was not roasted. This procedure involved acid leaching the ore, flotation and roasting of the carbonaceous material, and acid leaching the roaster calcine.

Development of an Ion Exchange Process for the Recovery of Vanadium

Description: A process for recovering vanadium from acid leach liquors by ion exchange using either columns or resin-in-pulp has been developed. The process is economically feasible, and operating techniques were developed which made the process practical from an operating standpoint. The theory, chemistry, and characteristics of the vanadium ion exchange process are fully discussed.

Effect of pH and Concentration of Ammonium Persulfate on Colorimetric Determination of Nickel by Dimethylglyoxime Method

Description: The following report records the study of the optimum pH of the method of the colorimetric dimethylglyoxime for nickel before the addition of oxidant and the concentration of ammonium persulfate needed to insure complete oxidation to higher nickel valence states and thus prevent precipitation of less soluble nickelous salt that was made. Results of this study is presented in Table 1.

Experimental Investigation of the Effect of Entrance Width-to-Height Ratio on the Performance of an Auxiliary Scoop-Type Inlet at Mach Numbers From 0 to 1.3

Description: Memorandum presenting an investigation of variable-area auxiliary inlets intended to provide for the variation of engine air requirements with speed and altitude. Three auxiliary scoop inlets were tested in combination with a nose inlet at a range of Mach numbers tested at zero angle of attack.

Flight Determination of the Pressure Recovery and Drag Characteristics of a Twin Side-Inlet Model at Transonic Speeds

Description: Report presenting free-flight and free-jet testing of a twin side-inlet configuration, including a pilot's canopy and a wheel-well fairing, between a range of Mach numbers from 0.8 to 1.55. Using side inlets provides two important advantages: the inlet can be located closer to the engine and it frees up the nose for other uses. Results regarding the effects of oscillating flow, external-drag coefficient, and total-pressure recovery are provided.

HRT-CP: Results of Solids Dissolution Tests

Description: A dissolution cycle in the chemical plant consists of refluxing with 10.8 M H2SO4 for 4 hours followed by refluxing for a like period with 4 M acid. In each of 3 tests in which 370 gram batches of simulated corrosion product solids were subjected to two dissolution cycles using 820 excess acid more than 99.6 of the solid material was dissolved (based on the amount of undissolved material collected). In another test using one dissolution cycle and 820 excess acid 99.5 of the solids material was … more

An Investigation of the Stream-Tube Power Losses and an Improvement of the Diffuser-Entrance Nose in the Langley 8-Foot Transonic Tunnel

Description: Report presenting surveys of the distribution of total pressure, total temperature, and static pressure at a number of stations in the slotted test section and diffuser of the transonic tunnel with early and improved diffuser-entrance noses installed at the ends of the slots. Results regarding power losses with the original diffuser-entrance nose, development of revised diffuser-entrance noses, and energy losses in the tunnel with the final diffuser-entrance nose are provided.

THE ISOTRON

Description: Most methods of separating isotopes depend on the use of a large magnetic field. The isotron is an electromagnetic device for separating isotopes, but it effects the separation by the use of radiofrequency voltages instead of magnetic fields. It has the advantage that plane sources of large area can be used instead of the slit sources to which most magnetic methods are limited. Before entering into any discussion of the details, a simplified description of the principles of the method is given.

Preliminary Internal Performance Data for a Variable-Ejector Assembly on the XJ79-GE-1 Turbojet Engine, 2, Afterburning Configurations

Description: Internal performance of an XJ79-GE-1 variable ejector was experimentally determined with the primary nozzle in two representative after-burning positions. Jet-thrust and air-handling data were obtained in quiescent air for 4 selected ejector configurations over a wide range of secondary to primary airflow ratios and primary-nozzle pressure ratios. The experimental ejector data are presented in both graphical and tabulated form.
