Collector
The feather depicted in the hieroglyphs is a tall Ostrich plume whose tip bends over under its own weight. Ostrich feathers are used in dusters because they're effective by means of the tiny barbules on the feathers themselves that hold intrinsic electrostatic charge. This charge allows the feather to lift dust from the surface of objects, therefore the Ostrich feather symbolizes a 'Collector'.
The Ostrich feather is used to represent the Suns plasma wing as a collector of negative charge, describing the mechanism behind the anodic positively charged Sun.
