Definitions

  • My invention has for its object an arrangement for diverting electrostatic charges from the outer surfaces of material having a poor conductivity through the agency of glow discharges.
  • a barshaped member of a rectangular cross-sectional outline made of insulating material and carrying on at least one of its lateral surfaces a series of parallellongitudinally extending wires forming the electrodes while there are formed in said member between said wires and in parallelism therewith, recesses inside which recesses are fitted rule-shaped counter-electrodes carrying electrode points projecting freely outwardly but stopping short of the outer edges of said recesses, this arrangement providing for the formation of a corona discharge field between said electrode points and the two adjacent wires, said field extending during operation throughout the lateral surface of the bar-shaped member.
  • Fig. l is a perspective view of a portion of an arrangement according to the first embodiment.
  • Fig. 2 shows in a similar manner a section of an arrangement according to a second embodiment.
  • the arrangement according to Fig. 1 includes a rodshaped member a made of insulating material such as hard or so-called bakelized paper material.
  • the upper surface of said member is provided with longitudinally extending, electrode-forming wires b secured in any suitable manner to the said member a. These wires are connected at one end of said rod-shaped member with a common grounding cable which is not illustrated. Between any two successive wires there is provided in the member a a groove-shaped recess c extending in parallel with the wires and in which are fitted rule-shaped electric leads d forming counter-electrodes.
  • leads d carry each a plurality of electrode points d1 projecting outwardly of the leads without extending beyond the corresponding recess 0, the different leads being also connected in registry with the one of the rod-shaped members a with a common cable which is not illustrated.
  • the cable feeding ice the leads ,d is connected with a high voltage supply of alternating current while the cable connected with the wires b is grounded.
  • An apparatus for grounding electrostatic charges from the surfaces of materials having poor conductivity comprising a member'of insulating material having at least one flat surface with a plurality of parallel grooves therein, wires on said flat surface between said grooves and parallel thereto, said wires being grounded, an electrode in each groove having a plurality of points thereon extending outwardly to a level just below said fiat surface, and a source of high AC. voltage to one side of which said electrodes are coupled.
  • An apparatus for grounding electrostatic charges from the surfaces of materials having poor conductivity comprising a member of insulating material having a flat surface with a plurality of parallel grooves therein, wires on said flat surface between said grooves and parallel thereto, a common ground lead to which said wires are connected, an electrode in each groove having a plurality of points thereon extending outwardly to a level just below said flat surface, a common power lead to which said electrodes are connected, and a source of high AC. voltage to one side of which said common power lead is coupled.
  • An apparatus for grounding electrostatic charges from the surfaces of materials having poor conductivity comprising a member of insulating material having two flat surfaces each having a plurality of parallel grooves therein, wires on each flat surface between said grooves and parallel thereto, a common ground lead to which said wires are connected, an electrode in each groove having a plurality of points thereon extending outwardly to a level just below the level of said fiat surfaces, 21 common power lead to which said electrodes are connected, and a source of high AC. voltage to one side of which said common power lead is coupled.
