摘要： A press for removing liquid continuously from aqueous pulp comprises a cylindrical housing divided into an upper annular press chamber and a lower working chamber which are separated by a perforated de-watering disk. The press chamber is enclosed on its upper end by a varying height squeeze plate for varying the cross sectional area of the press chamber. The de-watering disk is carried on a rotatably driven shaft which is mounted centrally in the housing. The de-watering disk is configured for passing extensible blades, having a width equal to the width of the press chamber and slidably carried in holders which are joined to the de-watering disk and shaft. A cam which engages the blades is configured for varying the amount of extension of the blades continuously in a manner such that they extend into the press chamber into adjacency with the squeeze plate, substantially filling the press chamber at all times. As the shaft is rotated the pulp, which is supplied to the press chamber at its point of maximum cross sectional area, is moved by the blades in the direction of decreasing press chamber cross sectional area squeezing the liquid out of the pulp through the de-watering disk. The liquid passes into the working chamber where it is removed from the press. As the pulp is moved through the minimum cross sectional area of the press chamber it is pushed out of the press through an exit opening in the housing.

摘要： An apparatus for screening fibrous stock. A rotor is rotatably mounted within an open ended, cylindrical screen which is mounted in a hollow housing. Fibrous stock is introduced into the housing and rotation of the rotor causes the portion of the fibrous stock that will pass through the screen to do so. Any fibrous stock that passes through the screen is discharged from the housing. The rotor includes a cylindrical body member having a plurality of blade members attached thereto and spaced substantially evenly about the circumference of the body member and radiating outwardly therefrom. Each blade member has a leading edge and a trailing edge with the leading edge spaced farther from the body member than the trailing edge.
