Abstract: A fluid resistant control linkage assembly having a housing with interior and exterior sides. The control linkage has a circular groove defined in the exterior side of the housing. A ring is rotatably disposed with the groove. A handle is affixed to the ring and located outside the housing to input rotational motion to the ring. An opening is defined in the groove to provide access to the interior of the housing. An array of gear teeth or a yoke or a post is affixed to the ring at the opening.The groove may be fitted with at least one elastromeric washer which is supported by at least one concentric shoulder along said groove.

Abstract: An apparatus is provided for the storage and dispensing of packaged adhesive bandages and similarly shaped flat packaged units. The dispenser includes a drive unit base, which may be powered either manually or electrically. A cartridge is removably mountable to the top of the base. The cartridge holds a stack of packaged adhesive bandages on a floor in which is defined an elongated slot. A weight is provided to exert downward pressure against the bandages toward the cartridge floor. A roller with an elastic following finger attached to the roller is mounted within the housing and aligned with the slot in the floor. When the roller is rotated the following finger frictionally engages the lowermost bandage in the stack, urging it through an exit portal at one end of the cartridge. As the bandage is propelled through the portal, it displaces a resilient flap which covers the portal.
