Abstract: A barrier door system to control movement of persons through an opening within a cabin area of an aircraft. The barrier door system includes a track with an elongated shape with a first end and a second end. A barrier door includes panels that are pivotally connected together and one or more pins that extend outward from a top edge of the barrier door and are configured to engage with the track. The panels are configured to pivot together in a folded configuration at a stowed position, and to pivot outward away from the track in an extended configuration to extend across the opening at the deployed position.

Abstract: A barrier door system to control movement of persons through an opening in an interior space of an aircraft. The barrier door system having a frame with outer members that extend around a gap. A barrier door has a first panel and a second panel that are pivotally connected together with the barrier door pivotally connected to the frame. The barrier door is movable between a stowed position and a deployed position. The stowed position includes the first panel and the second panel folded together in an overlapping configuration and positioned in the gap in the frame and away from the opening. The deployed position includes the first panel and the second panel positioned away from the gap and extending across the opening.

Abstract: A barrier door system configured to be positioned at an opening within an interior of an aircraft. The barrier door system comprises a door that is movable between a stowed position away from the opening and a deployed position that extends across the opening. A lock is mounted to the door and configured to lock the door in the deployed position with the lock configured to be immediately movable from a locked position to an unlocked position from a forward side of the door and to delay moving from the locked position to the unlocked position from a rear side of the door.

Abstract: A combination monument for an internal cabin of an aircraft includes a housing defining an internal chamber. A lavatory is within the internal chamber. A galley is coupled to the housing.

Abstract: A crew rest system for an internal cabin of a vehicle, such as a commercial aircraft, includes a monument having a cart compartment configured to retain three or more galley carts. An access area having an entrance is on a side of the monument. The entrance leads into an internal passage having steps.

Abstract: An aircraft includes an internal cabin having a tapered area. A first seating system including three seats coupled together is within a row within the tapered area. The three seats include an inboard seat, a middle seat, and an outboard seat.

Abstract: The present invention comprises an improved method for refining cellulose that produces a highly refined cellulosic material. The method comprises soaking raw material in a mild NaOH using reduced temperatures and pressures, and refining the material with a plate refiner so that a waste water stream is reduced in volume and has a pH within a range of 8 to 9. The present invention also comprises a HRC gel having a lignin concentration of at least about one (1)% by weight, and a water retention capacity of about 25 to at least about 56 g H2O/g dry HRC.
