Abstract: A friction-braking apparatus for a transportation system, having at least one caliper, at least one piston structured and arranged to move the at least one caliper; and at least one brake pad arranged on the at least one caliper. The at least one caliper is structured and arranged to selectively move the at least one brake pad into engagement with at least one rail of the transportation system.

Abstract: A container for a PC card including a relatively hard base pivotably connected by a hinge to a cover. A resilient tray is positioned within the base. The cover can be kept in a closed position by a latch. An outer edge of the tray attaches to a peripheral lip on the base to form a bumper and a seal between the base and cover when the container is closed. The edge also prevents shear movement of the cover relative to the base when the container is dropped on a corner. The hinge and latch are inboard of the outer edge of the tray so that they aren't disturbed if the container is dropped. The tray includes a central receptacle that receives the PC card. Between the PC card receptacle and the outer edge of the tray there is formed a bellows-like member which tangents the cover and base and physically isolates the PC card receptacle from the cover and base.

Abstract: A CD package including a CD holder and a foldable cover for the holder. The CD holder includes a tray and base in telescoping relationship, one of the tray and base being glued to the foldable cover. The CD holder includes edge projections and recesses which cooperate with edge projections and recesses of other CD holders to allow stacking of the CD holders to facilitate automated assembly. The base and tray also include ramped stops and cooperating projections, respectively, inward of the sides, to releasably lock the tray and base in the telescoped and untelescoped positions. Tabs are provided on the sides of the base to abut the tray and improve stability of the base relative to the tray in the untelescoped configuration. A transparent window is assembled on an end cap via a tongue and groove connection and then welded. Detents are added adjacent a recess formed on each side wall of the end cap, which recesses cooperate with a projection on the tray to connect the cap and tray.
