  • Patent number: 5437844
    Abstract: A cooling system for the high voltage electrode of a corona treater includes an elongated hose disposed within the dielectric tube and around which the high voltage wire is spirally wound. The elongated hose is connected to a first port through which cooling fluid is introduced. The cooling fluid flows through the hose and out an open end into the dielectric tube. The cooling fluid then flows out of the dielectric tube through a second port and back to a reservoir after passing through a high voltage isolator.

  • Patent number: 5293043
    Abstract: An electrode assembly for a corona treater of the type having an electrode magazine in which at least one high voltage electrode is mounted and a support tube on which the electrode magazine is removably mounted includes a plurality of projections extending outwardly from a mounting block disposed on the support tube and a plurality of projection receiving slots disposed on a pair of exterior guard plates mounted on the electrode magazine so that the electrode magazine may be releasably connected to the support tube by sliding the projections on the mounting block into the slots on the electrode magazine.

  • Patent number: 5281174
    Abstract: A high voltage connector between the elongated electrode assembly of a corona treater and a high voltage source include a receptacle disposed at one end of the electrode assembly and having an insulated connector in contact with the electrode. The insulation extends out from the electrode assembly to define a cavity that accepts a plug-in that establishes electrical contact between the high voltage source and the electrode. The cavity has a cross-sectional area only slightly larger than a portion of the high voltage wire disposed within it.

  • Patent number: 5278409
    Abstract: An apparatus for positioning the electrode assembly of a corona treater includes a rotatable cylinder to which the electrode assembly is attached. A counterweight is disposed on the cylinder substantially opposite the electrode assembly and the counterweight causes a torque equal and opposite to that created by the electrode assembly. A pneumatic piston is utilized to rotate the cylinder between its operative and threading positions.

  • Patent number: 4684803
    Abstract: A corona discharge device having a roll electrode and a segmented corona discharge electrode assembly mounted in a spaced relation to the roll electrode, the electrode assembly including a number of electrode segments mounted in a staggered relation with respect to said roll electrode, each segment including a hollow tubular electrically conductive electrode and a cup-shaped insulator mounted on the end of the electrode, the insulator including a base having an opening in the center, a tubular wall section surrounding the outside of the electrode and a vent tube aligned with the opening in the base and extending into the electrode to provide a vent passage for drawing air or blowing air across the face of the surface of the base of the insulator, and an electricity conductive adhesive for securing the insulator to the electrode and providing an even electrical field between the base and the surface of the base race electrode.
