20100284701 | System And Method For Tunable Chromatic Dispersion Compensation - One embodiment sets forth a technique for measuring chromatic dispersion using reference signals within the operational range of amplifiers used to refresh data signals. One red/blue laser pair in the transmission node is used for measuring dispersion and chromatic dispersion compensation is added at each line node in the system.

20100284749 | Systems and methods for off-shore energy production and carbon dioxide sequestration - The present invention is directed to aquatic systems and methods for off-shore energy production, particularly to systems and methods for generating large amounts of methane via anaerobic digestion, purifying the methane produced, and sequestering environmentally deleterious by-products such as carbon dioxide.

Off-shore energy production facilities supported by water bodies offer many advantages over land-based digesters, including the use of large, available open water bodies as an alternative means of support and the potential for locating the facilities at sites that already contain, or can be easily modified to generate, sufficient amounts of feedstock onsite. In addition, the containers of the present invention can be large enough to provide adequate amounts of energy to support off-shore activities and relatively easy to manufacture and ship to remote production sites. The systems can also be readily adapted to sequester carbon dioxide or replenish feedstocks growing nutrients on site. | 2010-11-11 |

20100284788 | DUCT WALL FOR A FAN OF A GAS TURBINE ENGINE - A duct wall of a fan casing of a gas turbine engine comprises an intake section and a containment casing, which are interconnected by bolts at flanges. An acoustic flutter damper is provided between the flanges to reduce or eliminate flutter arising in blades of the fan at certain important operating conditions. The damper provides flexibility at the connection between the intake section and the containment casing so that, in the event of detachment of a blade or a bladed fragment, the resulting deflection wave in the containment casing can be accommodated by displacement and/or deformation of the acoustic flutter damper, reducing the risk that the bolts will shear to allow the intake section and the containment casing to become detached from each other. The acoustic flutter damper may comprise a circumferential array of separate segments. | 2010-11-11 |
20100284789 | DAMPING ASSEMBLY - Fan flutter is a significant problem with regard to gas turbine engines and can lead to premature failure and unacceptability with respect to engine operation. Traditional acoustic liners for noise abatement are formed to reduce environment noise. Fan flutter frequencies are typically much lower than community noise targeted by traditional acoustic liners, and therefore require different approaches with respect to attenuation. By altering the acoustic propensities of the intake duct, it is possible to increase the safe operating envelope of the engine. The flutter attenuators according to this invention are optimised so that they occupy the minimum area of the intake duct, and so can be accommodated more easily (without significantly compromising the area available for liners targeting community noise, for example). In such circumstances resonators for flutter frequencies are typically associated with existing acoustic liner and take the form of chambers incorporating labyrinthine cores for absorption of acoustic frequency waves or utilise Helmholtz chambers with appropriate volumes and inlet pipe aperture configurations for tuning to desired flutter frequencies to be attenuated. | 2010-11-11 |
20100284790 | DUCT WALL FOR A FAN OF A GAS TURBINE ENGINE - A gas turbine engine fan casing duct wall comprises an intake section and a containment casing, provided respectively with flanges. An acoustic flutter damper is secured between the flanges. The acoustic flutter damper has a skin accommodating an internal structure that dampens fan blade flutter. The skin is secured to the flanges at separate locations. In normal operation of the engine, the internal structure is sufficiently robust to support loads transmitted through the acoustic flutter damper between the intake section and the containment casing. If a blade or blade fragment detaches, the resulting deflection wave in the containment case ruptures the internal structure, and the load path between the intake section and the containment casing passes along the skin, which consequently maintains the connection between the intake duct and the containment casing, while permitting substantial radial deflection of the containment casing relative to the intake section. | 2010-11-11 |
