Abstract: A hubcap for an aircraft wheel includes an internal spider which engages an anti-skid transducer located in the wheel hub. The hubcap is constructed of one piece and has a conical configuration to provide increased strength as well as increased airflow inside the hubcap for improved heat dissipation.

Abstract: First and second face members (12, 14) are secured to the opposite sides of a honeycomb core (16) to provide a structural wall (10). A phase change material (22) is provided within the cells (20) of the wall (10), so that the wall (10) also has the capability of storing thermal energy. The thermal wall (10) may be constructed in the form of a removable shelf (28) for a container (30). It may be constructed in the form of a fixed wall (60) of a container. Such a thermal wall (10) can be constructed to be in the form of a serving vessel, e.g. a dish (FIGS. 14 and 16), a cup (FIG. 13), or the like.

Abstract: An adjustable seating system particularly adapted for use in a passenger aircraft, where there are a pair of tracks mounted in the floor of the aircraft, and a plurality of seating units mounted to these tracks. Each seating unit has a pair of interconnected traction wheels which have positive engagement with the tracks, so as to avoid skewing of the seating units as these are moved along the tracks. Pivotally mounted locking members lock the rear leg portions of the seating units to the tracks at selected locations. Telescoping track cover members cover the track sections that extend between adjacent seating units.

Abstract: A roller assembly to be used to support cargo which is being moved over a floor surface. The assembly comprises an elongate horizontally disposed mounting member with roller units mounted thereto. Each roller unit comprises an outer roller member, two support bearings, two locating elements, a center shaft, and an end nut. Each locating element has cylindrical portions surrounding the shaft and butting against one another.

Abstract: A mounting member having an upper peripheral side wall to receive a ball member, and a lower connecting portion to be placed in locking engagement through a bottom opening in a base member. The side wall is positioned within a base support member for limited up and down movement; a plurality of spring-like washers are positioned between the mounting member and the base support member to urge the mounting member and the ball member which it supports to an upper support position.

Abstract: An improved gasket for a panel assembly to close an access opening for the wall of a wing mounted fuel tank in an aircraft. The gasket comprises a lubricant impregnated wire mesh material, having at its edge portions annular seal members, with the material of the seal members being impregnated in the mesh elements at the edge portions of the wire mesh material. The gasket is positioned between a clamping ring which is in bearing relationship against the panel and an edge portion of the wall of the fuel tank.
