A lock which operates reliably and quietly has a locking mechanism with a rotary latch and at least one ratchet pawl for latching the rotary latch. The lock comprises two faces which at least partially bear one against the other and which are at least recurrently displaced relative to one another, with the result that that the displacement causes frictional forces to occur between the faces. At least one frictional face is part of a rotatable component of the lock. A lubricant reservoir is assigned to this rotatable component. There is a feeding means from the lubricant reservoir to the frictional face, which means is configured in such a way that the lubricant is transported from the lubricant reservoir to the frictional face of the rotatable component.

A containment device to house an oil wicking process to protect, clean, and/or lubricate a metallic item or tool includes a containment housing with a wicking oil inside of the containment housing. At least one slot is positioned through the containment housing. Each of the at least one slots is configured to receive a working portion of the metallic item or tool. Wherein, when the working portion of the metallic item or tool is inserted into the slot, the working portion of the metallic item or tool is submerged into the wicking oil. Wherein, the wicking oil is configured to lubricate, protect or clean the working portion of the metallic item or tool.

A cleaning structure for a payload retrieval apparatus includes a main body having an upper end and a lower end. The upper end includes a tether attachment point. The cleaning structure also includes a first cleaning component extending outward from the main body. The first cleaning component has a flexible construction for fitting into crevices in the payload retrieval apparatus and defines a cleaning zone around the main body.
