ABSTRACT:
A device for dissipating and discharging undesired electric charges, especially from airplanes. The device is formed from nonmetallic conductive material, such as carbon loaded plastic, and comprises a number of regions having varying conductivities. A region at a first end where the device is connected to a mass to be discharged has a lower conductivity than a region at a second end. The device includes a coating comprised of insulating material, which coats the entire surface of the nonmetallic material except for a portion of the nonmetallic material on the second end of the device. A magnetic flux is created which pulls charges from the mass through the device. The charge is in part dissipated in the nonmetallic material and is in part discharged into the air through the exposed portion.
