Preliminary performance data for the J57-P-1 turbojet engine at altitudes up to 65,000 feet

Report presenting an investigation to determine the high altitude performance of the J57-P-1 turbojet engine and components conducted at the NACA Lewis altitude wind tunnel. Four conditions were tested: engine operation with both the compressor bleed ports closed, with the large compressor bleed port open, with both compressor bleed ports open, and normal engine operation with the automatic control.

Investigations of Ion Exchange Methods for Recovery of Uranium From Liquors Produced by Acid Leaching of Gunnar Ore (open access)

Investigations of Ion Exchange Methods for Recovery of Uranium From Liquors Produced by Acid Leaching of Gunnar Ore

An ion exchange testing program was completed on Gunnar acid leach liquors and pulps. A standard column system and a resin-in-pulp system, both using anion exchange resins, were investigated. The Gunnar leach liquors are readily amenable to the recovery of uranium by ion exchange.
