  • Patent number: 11440655
    Abstract: A device for controlling thrust vectoring of a cyclorotor includes a control cam positionable relative to a drive shaft of a cyclorotor along each of a first axis and a second axis, where the drive shaft is rotatable about a third axis. The device may further include a frame having a plurality of sides, where the frame is disposed at least partly around the drive shaft of the cyclorotor, a first positioning assembly disposed on a first side of the frame, where the first positioning assembly is structurally configured to move the frame along the first axis, and a second positioning assembly disposed on a second side of the frame, where the second positioning assembly is engaged with the control cam and structurally configured to move the control cam relative to the frame along the second axis.

  • Patent number: 9346535
    Abstract: A new ring cam and ring cam assembly, developed for providing more diverse dynamic pitching schedules for cyclorotor blades, particularly for providing both cyclic and collective pitch control, can be used for any apparatus where dynamic variation of cam controlled movement is needed. The new ring cam has its cam surface on the inside of a ring, the cam surface defining a plurality of different cam profiles which can be dynamically chosen and applied according to need. The different cam profiles are provided by different configurations and by combinations of those configurations. One configuration uses a plurality of adjacent different cam profiles across the inside width of the ring, so that a cam follower follows different cam profiles as it moves across or relative to the cam surface. Another configuration moves a center axis of the ring in relation to the axis of rotation of the cyclorotor, or other rotating device, to dynamically change the effective cam profile.

  • Patent number: 8459284
    Abstract: An apparatus for preparing a chemical solution includes a lower housing and an upper housing. The lower housing has a base, an upper plate having a central opening, and a side wall. A grid mounted on the upper plate covers the opening. A wall within the lower housing divides the interior of the lower housing into a central inner chamber and an annular outer chamber; this wall extends into an upper portion of the lower housing. One portion of the wall has a reduced height to permit fluid flow from the inner chamber to the outer chamber. A nozzle is mounted in the inner chamber for discharging fluid into the inner chamber, and causes local elevation of a portion of the fluid surface above the grid. The nozzle may be an eductor creating a venturi effect to draw fluid into the eductor.
