  • suitable passageways such as 22 and 24 are provided for respectively supplying the lighter liquid under pressure to the peripheral area of the rotor 16 and removing the heavier liquid therefrom.
  • Communicating with the passageway 24 for removing the heavier liquid may be passageways 26 provided between the spill-over discs 28 and end plates 30 of the rotor 16.
  • a plurality of concentric cylindrical separator bands 32 is mounted in the spill-over discs 28 as indicated.
  • the separator bands 32 are completely imperforate over their entire areas save for a plurality of holes arranged and aligned to afford series of disc column cavities such as 34, 36, 38 and 49.
  • the spacing between the separator bands 32 preferably should increase with increasing radius, or at least be uniform, although the spacing may also be made to decrease with increasing radius if desired.
  • Removably positioned within each of the cavities 34, 36, 38 and 40 is a novel disc column of the general type described in my co-pending application and indicated generally by the numeral 42.
  • the disc column 42 comprises a tie rod 44 having a threaded extension 43 at the inner end thereof, said threaded extension being adapted to be received in threaded openings suitably drilled and positioned in the drive shaft 12 of the device 16.
  • the tie rod 44 is preferably polygonal in cross-section, and in the embodiment illustrated the same is octagonal (see FIGS. 3 and 4), although other polygonal configurations may likewise be employed. The reasons for the polygonal construction of the tie rod 44 will become apparent as the description proceeds.
  • each of the disc assemblies 45 comprises a top disc 46 and a cooperating bottom disc 48 lying in face-to-face superposed relationship. All of the discs 46 and 48 are provided with a central opening 54) having the identical polygonal configuration as the tie rod 44, and through which said tie rod is threaded for operationally retaining said discs.
