Abstract: A continuous feed discharge surface treater for treating web materials has a discharge chamber where ionization of a process gas occurs defined and contained by one or more rollers. Enhanced chemical coronas and plasmas are achieved by limiting depletion of the gas chemistry from the discharge chamber and dilution or contamination from mixing with drawn in ambient air. Atmospheric coronas can also be achieved in which minimal or no ozone is exhausted from the treater. Various roller and electrode assemblies, including both fixed and rolling electrodes, can be employed.

Abstract: A corona treatment apparatus has a rotating roller electrode and a stationary electrode assembly for treating material passing over the roller electrode. The stationary electrode assembly includes an electrode support that extends along the roller electrode and is spaced therefrom. A one-piece dielectric element is positioned between the electrode support and the roller electrode with the material to be treated passing therebetween. A plurality of conductive electrode elements are separately movable into a first position in contact with the one-piece dielectric element to produce a corona that treats material passing over the roller electrode. A separate over-the-center spring mechanism is provided to hold each conductive electrode element in the first, treatment position, or in a second, withdrawn position in which no corona is produced.

Abstract: A control system for an industrial inverting type power supply is disclosed which provides for both operational control and a diagnostic capability for the power supply. The operational control aspects includes measuring and displaying a plurality of operational signals from within the power supply, and for providing several automatic modes of operation for the power supply. The diagnostic aspects of the control system include measuring and displaying a plurality of diagnostic values, particularly the measurement of several waveform characteristic values of the switching waveform of the power supply. Other diagnostic capabilities include a set of remote inputs, each of which, when activated, triggers an entry into a history table, thereby maintaining a record of remote input activations. Each remote input may also be configured with a descriptive message to be displayed on an operator display and a code which specifies the action that is to be taken by the control system when that remote input is activated.
