  • Articulating glide mechanism for asymmetric door operation
    Patent number: 6922871
    Abstract: The present invention includes an apparatus for guiding movement of an object along a track. The apparatus includes an attachment member defining an opening. A bushing is positioned in the opening and the bushing is laterally moveable within the opening. A plunger is attached to the bushing and the plunger is configured to move towards and away from the bushing. A guide mechanism is pivotably attached to the plunger and the guide mechanism is moveable along the track. According to other aspects of the invention, a slider is used in combination with a roller as the guide mechanism.

  • Flow-efficient, static pressure-shielding, fire-resistant decompression panel assembly
    Patent number: 6435455
    Abstract: A decompression panel assembly (12) for use in an aircraft separation structure (14). The panel assembly includes a support pan (26) having an opening (28), a bull nose (64) extending outwardly from the support pan at the opening's edge, and a recess (62) surrounding the bull nose. An inner seal (70) is sized and located within the recess (62). A retaining ring (22) is provided and includes a number of fingers (84) formed from spaced-apart slits (86) extending into the retaining ring (22) from the ring's inner edge. The assembly (12) further includes a pressure relief panel (24) shaped similar to the support pan opening shape, though sized slightly larger. The pressure relief panel (24) is held between the support pan bull nose (64) and the retaining ring (22) during non-decompression use. A number of index pins (94) interconnect between the retaining ring and the support pan. A grill (30) is attached to the support pan to protect the pressure relief panel.
