Hydrogen depolarized carbon dioxide concentrator performance improvements and cell pair structural tests
The investigations and testing associated with the CO2 removal efficiency and voltage degradation of a hydrogen depolarized carbon oxide concentrator are reported. Also discussed is the vibration testing of a water vapor electrolysis cell pair. Performance testing of various HDC cell pairs with Cs2CO3 electrolyte provided sufficient parametric and endurance data to size a six man space station prototype CO2 removal system as having 36 HDC cell pairs, and to verify a life capability exceeding six moths. Testing also demonstrated that tetramethylammonium carbonate is an acceptable HDC electrolyte for operating over the relative humidity range of 30 to 90 percent and over a temperature range of 50 to 80 F.

A new effect in the depolarization of resonant light scattering from molecules in the vapor phase: I2
Theoretical discussions of the depolarization ratios in two types of resonance processes are given. These processes are discrete state resonance fluorescence, and Raman scattering when the resonance is between a bound state and evanescent-dissociative states. Theory predicts a dramatic difference for these two cases due to a quantum mechanical phase cancellation in the case of virtual dissociative states. The predictions have been verified experimentally.

Integrated testing of an electrochemical depolarized CO2 concentrator /EDC/ and a Bosch CO2 reduction subsystem /BRS/
An oxygen reclamation system (ORS) in a spacecraft has the task to revitalize the spacecraft atmosphere by recovering the elementary oxygen from metabolically produced carbon dioxide and water vapor. Life support subsystems which can form such an ORS are an electrochemical depolarized carbon dioxide concentrator (EDC), a Bosch carbon dioxide reduction subsystem (BRS), and an oxygen generation subsystem (OGS). A total recovery of the oxygen from metabolically generated carbon dioxide can be obtained with the aid of system composed of the considered three subsystems. Attention is given to the control concept which assures an integrated operation of the EDC, BRS, and OGS. A description is presented of the test results obtained during 86 days of testing.

Ice depolarization of the Comstar beacon at 28.56 GHz during low fades and correlation with radar backscatter
Radar correlation with significant ice depolarization events accompanied by low copolarization fades of the 28.56-GHz Comstar beacon signal are described for an experimental program at Wallops Island, VA. Using a Faraday switch at the front end of the receiver, the copolarization and cross-polarization levels of the 28.56-GHz beacon signal are sequentially monitored. A nearby high resolution S-band radar pointing along the earth-satellite path monitors the simultaneous ice and rain reflectivity. For a first case considered, excellent correlation is noted between the cross-polarization events and relatively large and extended ice reflectivities along a segment of the earth-satellite path at altitudes near and above the 0 C isotherm. In a second case, the radar and receiver data strongly suggest the cross-polarization mechanism is due to a hailshaft which intersects the path at altitudes well below the 0 deg isotherm.
