"Nothing yet, Don," answered Wes. "We've been running some very interesting experiments, though."

Channing was interested in nothing but the non-duplicatable material, but he nodded. Wes Farrell's sideline experiments often paid off more than the main line of research.

"By inserting a filter circuit in the transmission beam, we can filter out other responses," said Wes. "Meaning that we can take a cube of regular iron, for instance, and run it through. The integrated iron in the receiver is pure iron, the purity of which is dependent upon the band-pass of the filter. Using alloy selectivity disks for filters in the circuits, we can make iron that is 99.99997% pure."

"Might be useful for metallurgical work, and so forth," mused Don. "Nine-nines iron is valuable and almost impossible—and it takes a gadget that destroys value to make it. Nice paradox, that."

"Another thing," said Wes. "We re-transmit the pure iron, and heterodyne the impulses into other elements. We can start with iron and end up with any of the other elements, merely by introducing the proper heterodyning impulse."

"That's not bad."

"I've got several elements that start off where the Periodic Chart ends. The boys in the chemistry lab are investigating the properties of Venium, Channium, Frankine, Ardenium, and Farrelline right now."
