Abstract: An aircraft passenger seat arrangement such as a business seating class arrangement including a plurality of passenger seat groups positioned adjacent a longitudinal aisle, each passenger seat group including an inboard seat and an outboard seat angled toward the longitudinal aisle, with the inboard seat angle being greater than the outboard seat angle to improve access to the outboard seat along a branch aisle extending from the longitudinal aisle forward of the inboard seat to a forward end of the outboard seat, as well as reducing seat pitch between longitudinally adjacent inboard and outboard seats with at least equivalent seat egress.

Abstract: According to one embodiment, an aircraft features a fuselage, a wing member, and two fuselage beam. The fuselage features a first plurality of structural supports, a second plurality of structural supports, a first opening disposed between the first plurality of structural supports, and a second opening disposed between the second plurality of structural supports. The wing member is disposed above the first opening and above the second opening. The wing features a plurality of ribs including a first rib and a second rib. The first fuselage beam couples the first rib of the wing member to the fuselage and has an elongated body portion extending across the first plurality of structural supports. The second fuselage beam couples the second rib of the wing member to the fuselage and features an elongated body portion extending across the second plurality of structural supports.

Abstract: A horizontally retractable covering for an architectural opening includes a headrail supporting a collapsible panel of material, a fixed rail securable to a side of the architectural opening and to a side edge of the panel, and a movable rail secured to the opposite side of the panel while being movable along the length of the headrail. An improved trolley connecting the top end of the movable rail to the headrail is provided so as to permit uniform gathering of the panel material along the horizontal extent of the trolley for improved aesthetics when the panel is fully extended across the architectural opening. A stabilizing cord system maintains a parallel relationship of the movable rail to the fixed rail to assure desired movement of the movable rail while permitting the aforenoted uniform gathering of the panel material.

Abstract: The invention related to an overlap of one pair of semicircles for the folding combining structure, wherein it have several yarn frame structure groups to one-way open or two-way open and one-way close or two-way close between left frame and right frame, and its characteristic lies in: Even rounds-lack overlap post consists of the left directional round-lack terminal surface plate and right directional round-lack terminal surface plate, among round-lack connected post insert in the left directional round-lack terminal surface plate and right directional round-lack terminal surface plate, and join the yarn frame structure group, so, can form several screen windows and rotate the two-way opening and closing or unilateral state that open and closing between the left frame of the window frame and right frame, in order to reach the theft-proof result of screen window.
