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 bumper construction for vehicles constructed of a single strip of metal roll-formed into a completely enclosed tubular member in which a foamed-in-place material is located in and completely fills only a central section of the tubular member a relatively short distance on each side of the central axis of the vehicle. An apparatus is provided for manufacturing roll-formed bumpers partially filled with a foam-in-place material, the bumpers including material defining a continuous closed section defining an open interior and opposing open ends. The apparatus includes a turntable with a plurality of holders including arms shaped to extend partially into the bumpers, and a plug on the end of each arm configured to block off the open interior of the bumper. The holders are pivotally mounted on the turntable so that a bumper can be slipped onto a selected holder, pivoted to an upright position, and then rotated by the turntable under an injector for dispensing foamable reaction injectable urethane (RIM) material.
