Abstract: A system of architecture, apparatus and calibration method is invented for high-power flexible-polarization payload for satellite communications. The system comprises onboard phase-tracked apparatus, flexible polarization mechanism, and in-orbit calibration method. The power combining and polarization performance of the phase-tracked payload is monitored on ground by measuring the cross-polarization discrimination (XPD) and/or axial ratio (AR). The high performance over the life is achieved by optimization of the XPD or AR on ground and adjusting complex gain of the transponders. The high-power flexible-polarization in-orbit-calibration payload may be applied but not limited to UHF, L, S, C, X, Ku and Ka-band high power satellite systems.

Abstract: Systems for servicing welding torches are provided, which include a feeder assembly and a nozzle cleaning assembly. The feeder assembly may be configured to feed removable components (e.g., contact tips). For example, the feeder assembly comprises a hopper magazine configured to store contact tips for a welding torch so that one contact tip is on top of another contact tip in their horizontal directions and to release each of the contact tips in the horizontal direction. The nozzle cleaning assembly may comprise a brush for cleaning the inner wall of the contact tip and a universal joint for off-centered rotation of the brush head.
