Abstract: A remote monitor system for a longitudinally positionable control bar having position indicating indicia thereon including a housing receiving the control bar therein and having an aperture in a sidewall communicating between the control bar and an exterior housing surface, an explosion proof enclosure mounted exteriorly of the housing and having a transparent window in alignment with the aperture, a video camera positioned within the explosion proof enclosure having a lens with a visual path through the window and in alignment with the housing aperture, a radio transmitter within the explosion proof enclosure connected to the camera and configured to transmit a signal of video images provided by the camera; and a battery power source within the explosion proof enclosure providing energy to the camera and transmitter for providing remotely receivable control bar position indicating images.

Abstract: A method for removal of pollutants from a pulping process byproduct liquor, the method comprising injecting an oxygen-containing gas into said liquor and condensing the water vapor from the stripping gas so as to produce a condensate comprising pollutants.

Abstract: The present invention provides a system for developing printing plate precursors. In one embodiment, the system includes a developer unit adapted to apply developer to printing plate precursors, a replenisher unit for controllably delivering replenisher to the developer unit and a regenerator unit for controllably delivering regenerator to the developer unit. The system may controllably deliver sufficient amounts of the replenisher and/or regenerator to maintain the volume and/or activity of the developer in the developer unit.
