Abstract

1,159,869. Centrifugal separators. G. N. HEIN. 22 Sept., 1967. No. 6227/69. Divided out of 1159868. Heading B2P. The subject matter of the present Specification is identical with that relating to Figs. 1 to 4 of the parent Specification but the claims are concerned with an air-driven centrifuge comprising a rotor having a lower surface resting on a supporting surface of a stator so that the rotor is supported when it is stationary, and means for introducing air between the lower surface of the rotor and the supporting surface of the stator including air jet means directed anguarly upwards to cause the rotor to rotate and be supported on an air cushion out of engagement with the supporting surface of the stator while so rotating, the supporting surface on the stator being provided by a stator ring which is mounted on the stator so as to allow the ring to move in a precessional and rocking manner thereby facilitating the stabilisation of the rotor during vertical speeds of rotation.
