  • Publication number: 20250179832
    Abstract: A fencing gun assembly includes a fencing gun that has a handle, a trigger movably integrated into the handle, a barrel and a grapple attached to the barrel. The grapple has a pair of gripping elements and a fence post can be positioned between the gripping elements. A cartridge is removably attachable to the barrel of the fencing gun which stores a plurality of fencing clips. The fencing gun shoots a single fencing clip outwardly through the barrel when the fencing gun is actuated. The pair of gripping elements bends the single fencing clip around the fence post and the fence wire thereby securing the fence wire to the fence post.

  • Publication number: 20120100986
    Abstract: A gas diffusion cathode for electrochemical cells provides higher power capability through the use of nano-particle catalysts. The catalysts comprise nanometer-sized particles of transition metals such as nickel, cobalt, manganese, iron, palladium, ruthenium, gold, silver, and lead, as well as alloys thereof, and respective oxides. These catalysts can substantially replace or eliminate platinum as a catalyst for oxygen reduction. Cathodes using such catalysts have applications to metal-air batteries, hydrogen fuel cells (PEMFCs), direct methanol fuel cells (DMFCs), direct oxidation fuel cells (DOFCs), and other air breathing electrochemical systems.
