Such power Is essentially free since the heat In the source would ordinarily go to vasts. 8tlll other features of the exhibit will be e bucket cf noise a lead enclosure containing a noise source to show lead's setad stopping power. The raucous buss drops to barely audible levels as soca aa the lead container's lid la replaced. Other lead products end recent developaents of lead technology will be available for Inspection and study by design engineers too. These Include leaded eeranlc finishes for glass, steel, ugnoalia end alwlm*, lead nuclear shielding, data ecocemii^ lead's acoustical properties, seaples of and data about lead anodes for corrosion protection, lesd-sold storage batteries, aad two novel dry bearings employing leaded Teflon aad lead Monoxide ceramic*. 9
