| Number | Title | Issue Date |
| 7762772 | Marine propeller with speed sensitive venting A marine propeller is provided with a valve that progressively blocks exhaust flow into aerating relation with the blades of the propeller as the propeller rotational speed increases. A piston within a housing moves radially outwardly, in response to centrifugal for... | 07/27/2010 |
| 7722323 | Axial flow turbine with overspeed preventing device An axial flow turbine motor is provided which includes a rotor with a peripheral row of drive blades and a peripheral band-shaped wall element radially clamped against the tops of the drive blades, and a housing with at least one pressure medium inlet nozzle and an ... | 05/25/2010 |
| 6474936 | Blower impeller apparatus with one way valves Blower designs for vented enclosures include an impeller having a plurality of blades. A plurality of one way valves are interleaved between the blades to permit substantial airflow only in one direction. One valve design incorporates flaps coupled to eit... | 11/05/2002 |
| 6082968 | Centrifugally activated variable damper assembly A centrifugally activated variable damper assembly for a stopped-rotor aircraft is disclosed for adjusting dampening level of teetering motions produced by the rotors during the in-flight conversion process from rotary-wing to fixed-wing flight, or vise v... | 07/04/2000 |
| 6077040 | Control system for blades for a variable pitch propeller A system for controlling propeller blade pitch is disclosed. The system comprises a transfer tube, wherein the transfer tube defines an element of the rotatable portion and wherein the transfer tube is non-translating relative the rotatable and non-rotata... | 06/20/2000 |
| 5366343 | Self-adjusting torque-responsive variable-pitch boat propeller A self-adjusting variable-pitch propeller has a drive shaft rotatable about a shaft axis in a predetermined forward rotational sense, a hub carried on the drive shaft and limitedly rotatable relative thereto about the shaft axis both in the forward rotati... | 11/22/1994 |
