Shipping container This copper-finned container developed at Battel le Memorial Institute prevents excessive heat buildup in the SNAP-27 plutonium-238 power source during shipment. A bed of nickel spheres acts as primary heat-transfer agent. A mixture of water and ethylene glycol serves as both secondary coolant and shielding
Fume incinerator This portable fume incinerator designed by Air Preheater Co. is used by Ford to evaluate direct-flame burning of fumes from auto-paint bake ovens. A recuperative heat exchanger is used to evaluate heat recovery. The installed system eliminates vapors and recovers enough heat to reduce fuel needs
Supersonic tire The supersonic tire shown here is being subjected to simulated flight conditions. The tire is heated to above 250° F. to simulate wheel well environment. Landing speeds in excess of 300 m.p.h. are duplicated at Goodyear by pressing the tire against the flywheel in the background
Rotor hub A Lockheed-California employee examines a titanium rotor hub developed for the U.S. Army AH-56A Cheyenne. The hub, machined out of four titanium forgings and then electron welded, has a 10-foot span. First flight of the 250-m.p.h. vertical takeoff and landing craft is scheduled for this year
Refractory sleeves A worker at the Pittsburgh works of Jones & Laughlin Steel sets a 5 0 % alumina content stopper rod in a 350-ton-capacity steel ladle. The high-alumina-content sleeves, produced by Minerals/Refractories division of Howmet Corp., provide required rod insulating properties, retard refractory erosion at the slag line, and reduce costs
