摘要： A power electronics cooling system includes a ram air fan with one or more blades and a ram air fan motor connected via an output shaft. The ram air fan draws in air and passes it across a heat exchanger to cool one or more cooling liquids. One or more pumps pressurize and pump the cooling liquids to various electronic components, including one or more motor controllers. The pumps may be mechanically or electrically coupled to the output shaft of the ram air fan, such that the motor of the ram air fan provides energy to the pumps.

摘要： Within an ion pump, accelerated ions leave the center portion of an anode tube due to the anode tube symmetry and the generally symmetrical electric fields present. The apparent symmetry within the anode tube may be altered by making the anode tube longitudinally segmented and applying independent voltages to each segment. The voltages on two adjacent segments may be time varying at different rates to achieve a rasterizing process.

摘要： A fluid transfer coupling is described that includes first and second connectable coupling members that together contain a sealed interior space when connected. A gas or steam purge inlet and a purge outlet are disposed in fluid communication with the sealed interior space for purging potential contaminants out of the interior space. The coupling also includes a vacuum port in fluid communication with the sealed interior space for drawing a vacuum on the sealed interior space and optionally testing the space for an adequate seal. The first coupling member includes a first fluid transfer conduit and the second coupling member includes a second fluid transfer conduit. The first and second fluid transfer conduits are positioned such that they can be connected together within the sealed interior space when the first and second coupling members are connected.
