    摘要： A guillotine damper for a duct is provided with a thrust frame upstream of the path of a blade that is movable into and out of an operative position in sealing engagement with a seat downstream of the blade path when the flow path is not obstructed by the blade and in sealing engagement with and seating the blade against the seat when the blade is positioned to block the duct. Devices are provided with each utilizing resilient components to thrust the frame into its sealing positions and a hydraulic component to retract the frame when the blade is to be moved into or out of its duct blocking position. Each device exerts the force of either component to the frame through a series of mechanical elements spaced a substantial distance apart along the sides of the frames and connected thereto.

    摘要： Pulp sheet take-off apparatus which allows removal of drum valve parts from existing high vacuum rotary drum filters and significantly increases the production capability of existing and newly designed high vacuum rotary drum filters includes an enclosed take-off chamber that is mounted immediately adjacent and parallel to the face of the filter drum on the descending side thereof, the chamber being connected by piping to the filter drum barometric leg or other subatmospheric pressure source as a means of maintaining subatmospheric pressure in the chamber equal to or less than the internal pressure of the filter drum. A fixed pulp sheet slide is arranged to remove the pulp sheet from the filter surface while atmospheric air is prevented from entering into the chamber, and pulp sheet discharge mechanism includes a vaned discharge roll that is mounted immediately adjacent and parallel to the top surface of the stock slide structure and includes means for biasing the discharge roll against the pulp sheet and means for rotating the discharge roll in the direction of pulp sheet movement to draw the pulp sheet out of the take-off chamber between the roll and the stock slide structure. The pulp sheet may be discharged to atmosphere or directly to an air tight repulping or shredding vat following the filter drum, the repulping and shredding vats being directly connected to and maintaining the same subatmospheric pressure as the take-off chamber.
