Self-sealing propellant-actuated device eliminates atmosphere contamination
Device retains internally generated combustion products by a plug which seals the barrel end after projectile ejection. Since no blast wave is produced, only the projectile can disturb the surrounding surfaces and atmosphere.
Heiney, O. K.↗
Deadweight calibration of pressure gages without contamination
Calibration of pressure gages is accomplished by use of fluid chamber in conjunction with conventional single chamber hydraulic deadweight tester. System eliminates cleaning of gages with liquid oxygen after tests and is simple to construct and operate.
Hensley, D. R.↗
Optical contamination during thermal testing in vacuum
Comparative tests are described for optical degradation in vacuum systems served by oil-type or ion-type pumping operation. Results show that degradation occurs only during ultraviolet irradiation in vacuum systems with oil-type pumping systems and that it increases with exposure time. Degradation does not occur with ion systems.
