  • Publication number: 20200156085
    Abstract: A separator includes a preassembled drive and rotation system unit having an outer ring flange portion and a drive frame having an inner ring flange. The outer ring flange portion of the preassembled drive and rotation system unit is vertically connected to the inner ring flange of the drive frame. A rotatable drum is placed onto the preassembled drive and rotation system unit, in the drum at least one paring disk is arranged in a paring chamber, and one or more stacks each having one or more stackable intermediate elements are arranged between the inner ring flange and the outer ring flange portion in order to set an axial relative position at least between the drive frame and the drive and rotation system unit.

  • Patent number: 8514365
    Abstract: An immersion lithographic apparatus is described with a drain configured to remove liquid from a gap between an edge of the substrate and the substrate table on which the substrate is supported. The drain is provided with a means to provide liquid to the drain irrespective of the position of the substrate table and/or a means to saturate gas within the drain. Those measures reduce the variations in heat load due to evaporation of liquid in the drain.

  • Patent number: 8123667
    Abstract: A separator includes a rotatable centrifugal drum having a vertical axis of rotation. The separator includes a rotatable drive spindle to drive the drum, an hydraulic system located in an interior of the drum and at least one feed line to feed a control fluid to the drum, the at least one feed line having an outlet region. Further included is a ring non-rotatably connected to the drum, a gap located between one of the drive spindle and the drum and the drive spindle and the ring. The feed line leads out radially in front of the drive spindle in the outlet region. The outlet region is oriented and configured such that emerging control fluid is spread directly against the drive spindle, and a portion of the control fluid enters through the gap into the hydraulic system.

  • Patent number: 6033356
    Abstract: A centrifugal drum (1) has an inlet chamber (12) connected to a discharge chamber (10) via ducts (21), with the supplied fluid flowing radially through rib-free annular chambers (24, 25, 26) on the way to the discharge chamber (10). A through-flow resistance is thereby generated which ensures that the inlet chamber (12) is filled completely. Since the ducts (21) start in the vicinity of the inlet pipe (8), the acceleration of the supplied fluid to the speed of rotation of the centrifugal drum (1) occurs over a small diameter with the result that the stress on the centrifuged material is relatively low.

  • Patent number: 5865719
    Abstract: A self-emptying centrifuge drum has a collecting channel for emptying the drum and a fitting for introducing water into the collecting channel. The drum is rotatable and is hydraulically actuatable by water introduced into the collecting channel through the fitting. The collecting channel rotates with the drum about an axis of rotation and the fitting is stationary and has at least one outlet. A baffle extends up from below the collecting channel and between the collecting channel and the fitting and has a lower portion below the collecting channel and an upper portion extending into an area radially inward of the collecting channel with respect to the axis of rotation. The at least one outlet of the fitting is aimed at the lower portion of the baffle.

  • Patent number: 5848959
    Abstract: A mechanism for driving a centrifuge drum has a shaft housing and a vertical transmission shaft having an upper end on which a centrifuge drum is mountable. Upper and lower bearings mount the shaft for rotation in the shaft housing. A wheel is mounted on the shaft for rotation therewith and a drive belt rotates the shaft via the wheel. An oil pool provides an oil mist for lubricating the upper bearing. The lower bearing is immersed in the oil pool and the wheel is mounted on the shaft above the upper bearing.
