Abstract
658,526. Treating paper pulp. CONSOLIDATED MACHINE TOOL CORPORATION. Aug. 31, 1948, No. 22980. Convention date, Sept. 9, 1947. [Class 96] In a machine for carrying out continuously the process of Specification 660,570, paper pulp admitted at 26 is swept by a moving head 25 over a draining plate 40 on to a roughened plate 70 and another e.g. roughened plate 100 is mounted over them so that it can be moved towards them to press the pulp and across them to roll it. The inlet 26 may be in the middle of the plate 40 which may be surrounded by the plate 70 and the plate 100 may be moved eccentrically about an axis 84 extending in the direction of that of the head 25. The latter may have arms 28 which may curve spirally, may be close to the plate 40 and may have sloping upper surfaces. The plate 70 may have holes leading into annular channels connected to pipes 73 through which liquid may be obtained from or supplied to the pulp. One plate, e.g. plate 70 may be made in adjustable sections. The plates 70 and 100 may have toothed working surfaces and some teeth may be inclined thereto, pointing, for example, away from the inlet. The inclined teeth may be pyramidal and may be arranged symmetrically. The plate 100 may be moved periodically toward and from the plate 70 as by a pair of fluid-operated pistons 120 reciprocating in cylinders 121, Fig. 14, and connected to rocking plates 130 and 131 themselves connected through gimbals 140 and 142 with the plate 100. Fluid may be supplied to one end of each cylinder 121 through a valve 202, Fig. 17, a third cylinder 175 being connected through a valve 200 with the said end of each cylinder 121, a piston 176 being reciprocated in the cylinder 175 as by a cam 187 &c. Fluid may also be supplied to all three cylinders through a reciprocating valve 167 actuated as by a cam 170 and when the valves 202 and 167 are closed the three cylinders form part of a closed system in which movement of the piston 176 is transmitted to the pistons 120.
