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.

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.

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.
