Abstract: A tool for removing plugs from recesses obviates the need for a twist of the wrist in engaging a plug for removal. A plunger is carried by a housing and is supported for reciprocal axial motion between extended and retracted positions relative to the housing. A shaft of the plunger includes a first threaded section that is engaged in a nut carried by the housing and has threads pitched to allow relative axial motion to be converted to relative rotation between shaft and housing. A second threaded section of the plunger shaft is configured to tap into a plug in response to shaft rotation in a tapping direction, and has a shallower thread pitch than the first threaded section.

Abstract: A system for sealing an exposed area of a surface coated with a radiofrequency signal absorbing coating includes a heat-responsive compound that transforms from a solid state to viscous melted state at temperatures above a predetermined temperature and that returns to a solid state after cooling to temperatures below the predetermined temperature. The heat-responsive compound has a radiofrequency absorbing material for absorbing radiofrequency signals at approximately equal frequency to those that the radiofrequency signal absorbing coating absorbs. An applicator applies the heat-responsive compound in the viscous melted state to cover the exposed areas. An absorptive tape conceals any gap or fastener associated with the exposed area and absorbs radiofrequency signals having approximately equal frequencies to those of the radiofrequency signal absorptive coatings.
