Abstract: A well tool including a plugging device having an inner mandrel, an anchoring device and a sealing device. The tool also includes a junk catching device having an outer housing, a bore provided inside the housing and a receiving device provided in an upper end of the housing. A lower end of the outer housing is connected to an upper end of the inner mandrel of the plugging device. The receiving device comprises a receiving opening providing an opening into the bore and a junk guiding device for guiding junk into the bore via the receiving opening. The well tool further includes a valve device having a run state and a set state, where the valve device forms a termination of a junk container in the set state.

Abstract: An isotropic conductive adhesive having silver coated polymer beads within an adhesive matrix and a method of forming an isotropic conductive adhesive are disclosed. The mean average diameter of the polymer cores of the beads is less than 30 ?m, and the silver coating comprises interlinked silver deposits grown from dispersed nucleation sites scattered across the surface of the beads.
