WINDOW PROTECTIVE DEVICE Russian patent published in 1998 - IPC

FIELD: space engineering; protection of windows against space particles. SUBSTANCE: device includes circular permanent magnet at axial magnetization which creates field weakened in area of window aperture and strengthened towards periphery, thus reducing intensity of particle bombardment of window. These particles which possess their own magnetic field are magnetized from circular magnet or electrified under action of space medium deflecting from center of window to its periphery. EFFECT: enhanced efficiency. 2 dwg
