Patent number: 5437844Abstract: 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.Type: GrantFiled: October 25, 1993Date of Patent: August 1, 1995Assignee: Pillar Technologies, Inc.Inventor: William H. Bonner

Patent number: 5293043Abstract: 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.Type: GrantFiled: December 24, 1992Date of Patent: March 8, 1994Assignee: Pillar TechnologiesInventor: William H. Bonner

Patent number: 5281174Abstract: 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.Type: GrantFiled: November 12, 1992Date of Patent: January 25, 1994Assignee: Pillar TechnologiesInventor: William H. Bonner

Patent number: 5278409Abstract: 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.Type: GrantFiled: November 12, 1992Date of Patent: January 11, 1994Assignee: Pillar TechnologiesInventor: William H. Bonner
