"If a disk of proper proportions of silver, gold and platinum were used with the Trexar in connection with a "negative focalizer" (an accessory used in his magnetic engine, which he also calls his "polar radiator") the alloyed disk would exhibit high induced cohesion by adhering to this focalizer with such affinity as to become inseparable from it, notwithstanding any force which might be mechanically applied to pry them apart."
