| 20100058767 | SWIRL ANGLE OF SECONDARY FUEL NOZZLE FOR TURBOMACHINE COMBUSTOR - A combustor includes a primary combustion chamber and a secondary combustion chamber, one or more primary nozzles disposed in the primary combustion chamber and providing fuel to the primary combustion chamber, a centerbody assembly, a venturi disposed downstream of the centerbody assembly, and a secondary fuel nozzle housed within the centerbody assembly and extending towards the venturi and providing fuel to the secondary combustion chamber. The secondary fuel nozzle includes a fuel passage and an air passage, and a swirler positioned around the fuel passage and having one or more vanes projecting radially within the air passage, each vane having a trailing edge arranged at a swirl angle relative to a longitudinal axis of the secondary fuel nozzle, the swirl angle is greater than 45°. | 03-11-2010 |

| 20100110820 | MOTORIZED BONE CEMENT MIXING AND DELIVERY SYSTEM THAT AUTOMATICALLY TRANSFERS BONE CEMENT BETWEEN THE MIXER AND THE DELIVERY DEVICE AND THAT AUTOMATICALLY TERMINATES THE MIXING AND DELIVERY PROCESSES - A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a paddle for mixing the components in a mixing chamber and a piston that pushes the mixing cement into an attached delivery device. The system further includes a switch that disconnects the drive assembly that actuates the paddle and piston from its power source. The switch is automatically tripped by a follower that moves upon actuation of the drive assembly. Once the cement is mixed and transferred to the delivery device, the follower trips the switch to automatically deactivate the drive assembly. | 05-06-2010 |
| 20110194371 | MOTORIZED BONE CEMENT MIXING AND DELIVERY SYSTEM THAT ALLOWS A USER TO DETACH THE DELIVERY DEVICE FROM THE MIXER FOR DELIVERY - A bone cement mixing and delivery system including a mixer and a delivery device. The mixer includes a paddle for mixing the components and a piston that pushes the mixed cement into the attached delivery device. The delivery device includes a tube into which the bone cement is forced from the mixer, and a plunger that forces the cement out of the tube during the medical procedure. The tube includes an entry port through which cement is introduced into the tube from the mixer. A one-way valve attached to the tube allows the cement to flow from the mixer through the entry port. After the cement is loaded in the tube, the delivery device is removed from the mixer. The valve blocks flow out of the entry port when the plunger is depressed. | 08-11-2011 |

| 20090257306 | BONE CEMENT MIXING AND DELIVERY SYSTEM WITH AUTOMATED BONE CEMENT TRANSFER BETWEEN MIXER AND DELIVERY DEVICE AND METHOD OF MIXING AND AUTOMATED TRANSFER OF BONE CEMENT BETWEEN MIXER AND DELIVERY DEVICE AND METHOD OF MIXING AND AUTOMATED TRANSFER OF BONE CEMENT BETWEEN MIXER AND DELIVERY DEVICE - A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a mixing paddle and a mixing shaft connected to the mixing paddle. A motor operatively engages the mixing shaft to rotate the mixing shaft and the mixing paddle to mix the components in a mixing chamber. The motor also operatively engages a transfer mechanism. After a predetermined mixing period has elapsed, the motor automatically actuates the transfer mechanism to transfer the mixture to a delivery device. The mixture is then delivered to a target site, such as a vertebral body of a patient or other anatomical site. | 10-15-2009 |

| 20090250150 | Tire having a coated surface - A tire includes at least one outer structural element, wherein the at least one outer structural element is at least partially coated by at least one coating layer including a crosslinked composition obtained by reacting: (a) at least one polysulfide polymer; (b) at least one thermoplastic polymer having at least one hydroxyl group; with (c) at least one polyisocyanate. Preferably, the at least one structural element is at least one of the tire sidewalls. | 10-08-2009 |
| 20100024942 | Tire Having a Colored Surface - A tire includes at least one outer structural element, wherein the at least one outer structural element is at least partially coated by at least one colored coating layer including a colored composition including (a) 5% by weight to 50% by weight with respect to the total weight of the dry colored composition, of at least one crosslinked polymeric compound obtained by reacting (a | 02-04-2010 |

| 20110242338 | Stabilization of Captured Images - Images captured by an image capture device on a line of sight with an associated gyrometric system designed to supply gyrometric measurement data relating to the line of sight are stabilized. To this end, a first series of captured images is obtained. Then, a second series of stabilized images is obtained by applying, to the first series of images, an image stabilization based on gyrometric information. Then, a residual stabilization error is determined by applying a digital processing to the second series of stabilized images. Finally, the preceding three steps are repeated. On initialization, the gyrometric information corresponds to the measurement data supplied by the gyrometric system. Then, subsequently, the gyrometric information is obtained by correcting, on the basis of the residual error, the measurement data supplied by the gyrometric system. | 10-06-2011 |
