  • Centrifugal separator
    Patent number: 4820256
    Abstract: In a previously known centrifugal separator the separation chamber (4) of the centrifuge rotor has an inlet (9) for a mixture of two liquids and relatively heavy solids, a central outlet (23a) for separated light liquid and a periphery outlet (12) for separated solids. A third outlet (35) from the separation chamber (4), situated radially between the first said two outlets (23a, 12), communicates with a recirculation channel, which extends partly through a stationary structure and through which liquid may be conducted from the separation chamber (4) through a sensing device (38) and back to said inlet (9) for mixture. The sensing device (38) is arranged to initiate opening of the periphery outlet (12), when a certain amount of heavy liquid has been separated in the separation chamber (4). A throttle is arranged for limiting of the flow through the recirculation channel.

  • Brake with anti-locking and reapplication control and method
    Patent number: 4152030
    Abstract: Apparatus for braking a rotating member which has a fluid pressure responsive brake to which pressurized fluid is supplied for braking the rotating member, an anti-locking device interposed between the brake and the source of supply of fluid pressure for cyclically decreasing and increasing the fluid pressure supplied to the brake, and a control interposed between the brake and the fluid pressure source for limiting the rate of rise of fluid pressure supplied to the brake. Limitation of the rate of rise of fluid pressure applied to the brake governs reapplication of braking forces by the brake and thereby aids in optimizing brake performance.

  • Brake anti-locking modulator with reapplication control
    Patent number: 4138165
    Abstract: A modulator apparatus for use in a rotating member braking arrangement which has a fluid pressure responsive brake to which pressurized fluid is supplied for braking the rotating member, with the anti-locking modulator interposed between the brake and the source of supply of fluid pressure for cyclically decreasing and increasing the fluid pressure supplied to the brake. The modulator valving is constructed in such a way as to control the rate of rise of fluid pressure applied to the brake, thereby governing reapplication of braking forces by the brake and aiding in optimizing brake performance.
