20110171054ROTARY DEVICE - A device includes a ring having a tubular interior surface centred about an axis. The surface includes a plurality of axially extending, inwardly-projecting ridges. On opposite sides of each ridge is a first port and a second port. A rotor rotates in the ring about the axis. A plurality of vanes is mounted to the rotor body for rotation therewith and for radial extension and retraction relative thereto such that the surface can be swept by the vanes. The rotor and the ring are sealed to permit fluid communication into and out of the device only via the ports. The vanes retract and extend as the body rotates such that chambers are created which decrease in volume when in communication with the first ports and chambers are created which increase in volume when in communication with the second ports. A fluid pressure mechanism can cause vane retraction.07-14-2011

20110065518CONSTANT VELOCITY COUPLING - Disclosed herein is a constant velocity coupling of a new design and manufacture comprising an input shaft having a first wave surface thereupon, wherein the first wave surface comprises mounds and valleys. The constant velocity coupling additionally comprises an output shaft having a second wave surface thereupon, wherein the second wave surface comprises mounds and valleys. The constant velocity coupling additionally comprises a housing substantially enclosing the first wave surface and second wave surface, wherein rotational force exerted upon the input shaft is translated through the lobes of the first wave surface to the lobes of the second wave surface and to the output shaft in turn, and wherein the first wave surface and second wave surface transmit rotational force therebetween through any range of angles to a maximum output angle between a rotational axis of the input shaft relative to a rotational axis of the output axis.03-17-2011
20110133410HYDRODYNAMIC BORE SEAL - The disclosed finger seals are designed to be operational under rotational velocity or a stationary condition. The contact surface of the finger seals is inclined in an axial direction. This incline causes a convergent leakage path between the finger foot surface and the bore. Therefore, the leakage flow passing through this gap exerts hydrodynamic lift on the finger and lifts the finger from the bore surface at design pressure. Since the slope is in the axial direction, the rotational velocity of the bore does not affect the hydrodynamic lift and the finger seals can operate at any rotational speed, unlike prior finger seal where the hydrodynamic lift is generated by rotational velocity.06-09-2011

20120285282SPHERICAL INVOLUTE GEAR COUPLING - Disclosed herein are several embodiments of rotors (gears) which utilize spherical involute curves to determine the surfaces of the lobes (teeth). In some embodiments the contact surfaces are radial projections of spherical involute surfaces. In other embodiments the contact surfaces have a root and/or tip of a spherical involute curve, but are barreled or otherwise curved to reduce the point stress on each rotor. The rotors may also be configured where torque transfer is provided at a first set of lobes (teeth) and backlash removal is provided on teeth radially opposed to the first set of lobes (teeth). As the apparatus rotates, the position of torque transfer remains substantially the same, as does backlash prevention/removal, but the teeth providing these operations vary. The rotors may also be used for fluid flow.11-15-2012
