Abstract
A tool defines a piston/cylinder with first and second chambers on either side of the piston. A sealable port couples the first chamber to ambient environment. One end of the tool (i) defines a volume that is open to ambient environment, and (ii) has a cartridge coupled thereto such that the volume remains open to ambient environment. The cartridge defines (i) a chamber filled with a meltable material, and (ii) a channel coupling the material-filled chamber to ambient environment. A melting device in thermal communication with the meltable material simultaneously heats an air/water mixture in the second chamber and melts the meltable material. An element releasably coupled to the tool spans a region within the cartridge that lies within the channel. The element incorporates a check valve separating the volume defined by the tool and ambient environment.
