Automated brush plating process for solid oxide fuel cells

Patent Long, Jeffrey William [Pittsburgh, PA]

A method of depositing a metal coating (28) on the interconnect (26) of a tubular, hollow fuel cell (10) contains the steps of providing the fuel cell (10) having an exposed interconnect surface (26); contacting the inside of the fuel cell (10) with a cathode (45) without use of any liquid materials; passing electrical current through a contacting applicator (46) which contains a metal electrolyte solution; passing the current from the applicator (46) to the cathode (45) and contacting the interconnect (26) with the applicator (46) and coating all of the exposed interconnect surface.

Wire brush fastening device

Patent Meigs, Richard A [East Concord, NY]

A fastening device is provided which is a variation on the conventional nut and bolt. The bolt has a longitudinal axis and threading helically affixed thereon along the longitudinal axis. A nut having a bore extending therethrough is provided. The bore of the nut has a greater diameter than the diameter of the bolt so the bolt can extend through the bore. An array of wire bristles are affixed within the bore so as to form a brush. The wire bristles extend inwardly from the bore and are constructed and arranged of the correct size, length and stiffness to guidemore » « less
