摘要：
An apparatus for sealing a housing to prevent the escape of airborne material therefrom. Carrier beads are captured and suspended in a magnetic field extending across a region adapted to be sealed, forming a curtain of carrier beads for preventing the escape of airborne material, including toner particles, therepast. The carrier bead curtain is continuously collapsed and regenerated as carrier beads are captured, accumulated, and deposited into the housing.
