Abstract: An inflatable evacuation device includes an inflatable slide portion and an inflatable arch-shaped support portion for supporting the inflatable slide portion. The inflatable slide portion has a support frame with a first inflatable elongate beam and a second inflatable elongate beam spaced from the first inflatable elongate beam. A floor extends between the first and second inflatable elongate beams and is constructed of a flexible material. The inflatable arch-shaped support portion comprising first and second inflatable curved beams connected to the inflatable slide portion such that forces generated at least at a central region of the inflatable slide portion are transferred to the curved beams to thereby support at least the central region.

Abstract: An inflatable evacuation slide for an aircraft comprising upper and lower sliding regions interconnected by an intermediate sliding region and including a flexible sliding support surface. An inflatable support structure extends outwardly from the upper sliding region and formed by at least first and second support sections spaced from each other and extending in planes transverse to a plane of the sliding support surface. Each support section comprises an engaging member interposed between a connecting member and a supporting member. The connecting and supporting members are connected to the upper sliding region, so that the engaging members are substantially parallel to each other and spaced from the upper sliding region.

Abstract: An inflatable evacuation slide for an aircraft consists of first and second longitudinal support beams, upper and lower transverse support members and a flexible sliding support surface. The first and second longitudinal support members are spaced from each other and formed having proximal and distal ends thereof. The lower support member is transverse to the first and second longitudinal support beams and spaced from the distal ends thereof, so that each longitudinal support beam is formed having an extension portion extending between the lower support member and the distal ends thereof. The flexible sliding support surface is connected to and limited by at least the upper and lower support members.

Abstract: In an embodiment shown, the plug comprises a body having a central, threaded bore in which is received the threaded shank of a nosepiece. Jaws are slidably engaged with a ramp surface of the nosepiece for effecting a gripping engagement with the inner surface of a tube to be sealed. The body has an abutment formed thereon against which to receive a compression washer and a plurality or O-ring seals interleaved with other compression washers. The shank of the nosepiece is threadedly movable extensibly from and retractably toward the body by use of a wrench engageable with a hexagonal recess formed in the body-engaging end of the shank. As the nosepiece is retracted, the jaws slide along, and expand upon, the ramp surface. The O-ring seals and compression washers set against the abutment of the body, as noted, and an internally-threaded nut is threadedly engaged with an externally-threaded end of the body which is opposite the nosepiece.
