liquor to mixing tank and return it to cathode tank after agitation for specified time. Draws sample
of resulting slurry and determines specific gravity, using hydrometer. Positions cathode screen over
cathode tank, using crane. Connects vacuum hose to cathode and lowers cathode into tank for asbestos
coating, using hoist. Observes vacuum gauge to determine number of dips or immersion time necessary
to apply asbestos coating of specified thickness to cathode. Applies asbestos tape to secure cathode
rim. Transfers coated cathode to drying area, using crane. Records number of cathodes coated,
