| 20090269187 | Variable stator vane - A variable stator vane in a gas turbine engine has a journal provided with a circumferential recess. An aperture extends from the recess to a face of the journal directed towards the aerofoil portion of the vane. In operation of the engine, heated air, for example from a downstream compressor stage of the engine is admitted to the recess and flows through the aperture to, for example, the pressure surface of the aerofoil portion. The aerofoil portion is thereby heated, so preventing ice accretion on the vane. | 10-29-2009 |

| 20090014234 | Acoustic Panel - An acoustic panel for a fan casing of a gas turbine engine includes one or more Helmholtz resonators to absorb acoustic energy propagated upstream from the fan. By arranging that the periodic air flow out of the resonators has some axial momentum, by inclining the passages that from the necks of the resonators in a downstream direction, some of the energy in this air flow can be realised as a useful pressure rise in the direction of the air flow into the fan, rather than a pressure drop as in known acoustic panels. | 01-15-2009 |
| 20100206664 | Acoustic panel - An acoustic panel for a fan casing of a gas turbine engine includes one or more Helmholtz resonators to absorb acoustic energy propagated upstream from the fan. By arranging that the periodic air flow out of the resonators has some axial momentum, by inclining the passages that exit from the necks of the resonators in a downstream direction, some of the energy in this air flow can be realised as a useful pressure rise in the direction of the air flow into the fan, rather than a pressure drop as in known acoustic panels. | 08-19-2010 |
| 20120034072 | SEAL ASSEMBLY - A seal assembly arranged adjacent to a primary flow region, the seal assembly including: first and second components; a seal arranged between the first and second components to seal a secondary flow region from the primary flow region; and a first recess portion provided in the first component and arranged adjacent to the seal and the primary flow region, the first recess portion further being arranged to receive flow from at least one of the primary flow region and the secondary flow region and shed flow to the primary flow region, wherein the first recess portion is configured to promote a first flow feature within the first recess portion, the first flow feature flowing with a portion of the first flow feature adjacent to the primary flow region and the portion of the first flow feature being shed to the primary flow region in substantially the same direction as the flow in the primary flow region. | 02-09-2012 |

| 20080273972 | TEMPERATURE CONTROLLING APPARATUS - An apparatus for controlling the temperature of a component, which is situated in use in a gas stream, provides a nozzle to create a jet of air at an angle to the gas stream, the jet being directed into the region of the stagnation point of the component so as to control the temperature of the component. The invention is particularly suited to preventing or reducing the formation of ice on vanes of gas turbine engines, but may also be applied to other components, and may equally be used in situations where a component is to be cooled rather than heated. | 11-06-2008 |
| 20090214354 | NOSE CONE ASSEMBLY - A nose cone assembly for a gas turbine engine comprises a spinner and a plurality of circumferentially spaced mounting members for mounting the spinner on a fan hub of the gas turbine engine. Each of the mounting members is rigid in a generally axial direction and flexible in a generally radial direction. | 08-27-2009 |

| 20080210835 | Magnetic Attachment Apparatus - Provided is, among other things, an attachment apparatus that includes an attachment base, a magnet attached to a first side of the attachment base and a clip structure extending from a second side of the attachment base, the second side being opposite the first side. The clip structure, in turn, includes first and second arms which can be resiliently spread apart in order to receive an item and then released in order to close around the item. | 09-04-2008 |
| 20100132621 | Floating aquatic structure - Provided is a floating structure for use in an aquarium or other aquatic setting, having a manufactured hollow body with a top side, a bottom side and sidewalls extending between the top side and the bottom side. The hollow body is weighted so as to have a stable floating position in water such that the hollow elongated body predominantly remains submerged beneath the water's surface, but an outer surface of the top side consistently remains above the surface of the water. | 06-03-2010 |
| 20100139571 | AQUATIC APPARATUS WITH MIRROR - Provided are, among other things, aquatic apparatuses. In one, an aquarium is at least partially filled with water, and a mirror is disposed within the water, the mirror having a reflective surface area that is between 1-40 square inches. In another, an aquarium is at least partially filled with water, and a mirror is attached to, and thereby suspended beneath, a buoyant object in the water. In yet another, a mirror is attached a buoyant object, the mirror having a reflective surface area that is between 1-40 square inches. | 06-10-2010 |

| 20120072112 | SIGNAL VERIFICATION - A first position of a satellite is calculated at a first time in dependence on received orbit data corresponding to an orbit path of the satellite. Anan orbit path of the satellite is modeled from the first position at the first time to a second time to determine a second position of the satellite at the second time. A third position of the satellite is then calculated at the second time in dependence on the received orbit data. The second position and third position are compared to determine a validity of the orbit data. | 03-22-2012 |

| 20090025252 | FOOTWEAR | 01-29-2009 |
| 20090044432 | FOOTWEAR - An outsole unit for an item of footwear comprises a base layer of a flexible material having fibres extending from one surface, for example a napped leather such as pigskin suede or a textile material, and one or more lugs of thermoplastic polyurethane (TPU) moulded directly to the fibrous surface so as to form a tread. Multiple lugs may form a regular array separated by grooves, and may be connected solely by the base layer, by a skin of TPU extending across the base layer or by narrow connecting elements of TPU. An upper of an item of footwear may comprise a backing of suede leather with a grid of strips of TPU moulded to its napped surface. An item of footwear may comprise the outsole unit of the invention, the upper of the invention, or both. | 02-19-2009 |

| 20090078032 | Method for assessing degradation of a coating on a component by measuring its surface roughness - A method of assessing the degradation of an oxide-forming coating on a component after a period of operational use of the component, said degradation of the coating being caused by depletion of the oxide-forming element within a remnant coating layer due to inter-diffusion of said element between the remnant coating and both an outer oxide layer and an inner, secondary diffusion layer, wherein a depletion parameter indicative of the depletion of the oxide-forming element in the remnant coating layer varies as a function of the surface roughness of the coated component, the method comprising the steps of: carrying out a non-destructive, quantitative measurement of the surface roughness of the component after said period of operational use; and, based on an estimation of the functional relationship between the surface roughness and the depletion parameter, using the result of said measurement of surface roughness to quantitatively assess the degradation of the coating. | 03-26-2009 |
