Abstract: An aircraft wing including a fuel tank located in the wing, a channel defining a cavity in the fuel tank, the channel including at least two channel ends terminating at an upper or lower wing surface, a driveshaft located in the cavity; and an access panel located on the wing surface and being movable between an open position so that access to the cavity is permitted, and a closed position so that the cavity is at least partially covered by the access panel to inhibit access to the cavity.

Abstract: A vertical support system includes a first articulated leg assembly configured to carry a first load, the first articulated leg assembly being selectively movable between a first retracted configuration and a first loaded configuration and a second articulated leg assembly configured to carry a second load substantially kinematically identical to the first articulated leg assembly, the second articulated leg assembly being selectively movable between a second retracted configuration and a second loaded configuration. The arrangement of axis of rotations and offset angles of the first and/or second lees of each articulated leg assembly may produce a lateral width ratio. A first vertical footprint of the first articulated leg assembly overlaps a second vertical footprint of the second articulated leg assembly when the leg assemblies are retracted.

Abstract: A floor tile has a rectangular, wear resistant, decorated upper portion. A rectangular lower portion is affixed to the upper portion. The lower portion has laterally projecting tongues extending outwardly from two adjacent sides. The other two adjacent sides have inwardly directed pockets adapted to receive the tongues of adjacent tiles to form a continuous floor covering. Only the edges of the tongues and pockets that resist movement of adjacent tiles away from one another are close fitting to facilitate installation.

Abstract: A vertical support system includes a first articulated leg assembly configured to carry a first load, the first articulated leg assembly being selectively movable between a first retracted configuration and a first loaded configuration and a second articulated leg assembly configured to carry a second load substantially kinematically identical to the first articulated leg assembly, the second articulated leg assembly being selectively movable between a second retracted configuration and a second loaded configuration, wherein a lateral width ratio is equal to a value of less than about 0.6, the lateral width ratio being defined as a ratio of (1) a maximum lateral width when the first articulated leg assembly and the second articulated leg assembly are in a retracted configuration to (2) a maximum lateral width when the first articulated leg assembly and the second articulated leg assembly are in a loaded configuration.

Abstract: A system for recording and distributing information is described. The system includes a controller computer capable of establishing a communications connection via a communications interface with information providers and users. The controller computer also maintains a web site through which information providers can list and describe the information services to be distributed through the web site and through which users can browse to find information services to purchase. Information providers record information over the communications connection, which is stored in a database maintained on the controller computer. Users select to receive recorded information, which is delivered over the communications connection by the controller computer. The controller computer further has the capability of automatically billing users and crediting information providers for the information.
