Patent Images
1. Structure for bleeding off static electrical charge or an electric charge developed on a finite segment of an insulator surrounding an electrical conductor due to the existence of an electric potential along said segment between said conductor and a region adjacent said finite segment of said insulator, said structure comprising:
- a layer of semi-conducting pyrolyzed glass fiber material having resistivity in the range of 200 to 10,000,000 ohms per square in intimate contact with said finite segment of said insulator and in electrical contact with an electrical ground.

4. An assembly comprising:
-
a structure on which harmful electrical charge is prone to accumulate in the absence of its controlled bleed-off therefrom; and a layer of semi-conducting pyrolyzed glass fiber having a resistivity in the range of 200 to 10,000 ohms per square disposed in intimate contact with said structure and adapted for connection to a reference electrical potential so as to effect controlled bleed-off of harmful static electrical charge from said structure. - View Dependent Claims (5, 6, 7)
