20090189358 | SELF-ENERGIZED BACKUP RING FOR ANNULAR SEALS - An apparatus is disclosed in one embodiment of the invention as including an annular seal (e.g., an o-ring) and a backup ring to provide support to the annular seal. A gland is provided to accommodate the backup ring and the annular seal. The gland has a contact surface which is adapted to contact a corresponding contact surface of the backup ring upon inserting the backup ring into the gland. The diameters of the contact surfaces of the backup ring and gland are sized such that the contact surface of the backup ring radially interferes with the contact surface of the gland, thereby urging the backup ring out of the gland. A retention mechanism, such as interlocking grooves, protrusions, ridges, notches, slots, or the like may be provided in the backup ring and gland respectively to prevent the backup ring from completely exiting the gland. | 07-30-2009 |

20080291101 | METHOD AND APPARATUS FOR STEERING AND STABILIZING RADIO FREQUENCY BEAMS UTILIZING PHOTONIC CRYSTAL STRUCTURES - An RF beam steering device employs a prism assembly to steer an RF beam and a compensation device to address undesirable movement of the beam steering device. The prism assembly includes a plurality of dielectric prisms each with an associated impedance matching layer. The dielectric prisms are rotated relative to each other to steer the RF beam in a desired direction and further to compensate for movement of the beam steering device itself. The prisms include a plurality of individual panels with drilled or slotted openings that are arranged to create a periodic photonic crystal structure within a defined region. This configuration effectively alters the dielectric constant over any one particular region of a panel, thereby altering the level of diffraction possible for a specified panel thickness. The openings within each stacked panel are overlapped to produce the required level of diffraction and refractive index gradient. Motors rotate the prisms relative to each other to the correct orientation for steering the RF beam in a desired manner. | 11-27-2008 |

20150252723 | Compressor Areas For High Overall Pressure Ratio Gas Turbine Engine - A gas turbine engine comprises a high pressure turbine rotor, an intermediate pressure turbine rotor and a fan drive turbine rotor. The fan drive turbine rotor drives a fan rotor through a gear reduction. The intermediate pressure rotor drives a low pressure compressor rotor and the high pressure turbine rotor drives a high pressure compressor rotor. A first flow cross-sectional area is between an outer periphery of a hub in the low pressure compressor rotor, and an outer tip of an upstream most blade row of the low pressure compressor rotor. A second flow cross-sectional area is between an outer periphery of a hub in the high pressure compressor rotor, and an outer tip of an upstream most blade row of the high pressure compressor rotor. A ratio of the first and second flow cross-sectional areas is greater than or equal to about 0.12 and less than or equal to about 0.33. | 09-10-2015 |
20150361879 | GAS TURBINE ENGINE WITH EMBEDDED DISTRIBUTED FANS - An aircraft body comprises a support structure. A gas turbine engine comprises a gas generator having at least one compressor rotor, at least one gas generator turbine rotor, and a combustion section. A fan drive turbine is positioned downstream of at least one gas generator turbine rotor, and is configured to drive a shaft. The shaft engages gears to drive a plurality of fan rotors. The gas turbine engine is embedded into the support structure such that there is an inlet leading through the support structure to the fan rotors to deliver air to the fan rotors. A gas turbine engine is also disclosed. | 12-17-2015 |

20150137455 | TARGET STAND - A target stand is disclosed and described. The target stand can include a first side member and a second side member. Each side member can have a base portion, and an upright portion extending from the base portion. The upright portion can have a lower engagement feature and an upper engagement feature. The target support can also include a lower transverse member and an upper transverse member. Each transverse member can have a main body portion with a target support portion for interfacing with a target support, and complimentary engagement features extending from opposite ends of the main body portion. The complimentary engagement features of the lower transverse member can be securable to the lower engagement features of the first and second side members to secure the lower transverse member to the first and second side members. The complimentary engagement features of the upper transverse member can be securable to the upper engagement features of the first and second side members to secure the upper transverse member to the first and second side members. A distance between the complimentary engagement features of the upper transverse member can be different than a distance between the complimentary engagement features of the lower transverse member such that the lower and upper transverse members bind with the first and second side members and cause the first and second side members to be disposed at an angle relative to one another when assembled. | 05-21-2015 |
