Witness sun's defiance to human powers, Washington, D.C., September 8. Senor Adolfo Niebuhr, of Argentine, Dr. Richard Plobet, of Germany, and Dr. Eugen Melchinger, of Germany, witness the failure of Dr. Charles G. Abbott's sun ray machine. The device which is said to be capable of operating half-horsepower steam engine by the sun's heat failed when the concentrated heat proved too much for the soldier connections The men are representatives of their respective countries to the Third World Power Conference which is now being held in this city

Sun refuses to be harnessed, Washington, D.C., September 8. The scheduled exhibition of Dr. Charles G. Abbott's sun ray machine was ruined today because there was too much sun. The intense heat, after being concentrated melted the solder connections. Dr. Abbott, the inventor, then went ahead to explain his device which is said to be capable of operating a half-horsepower steam engine by the sun's heat. The exhibition was held in honor of some of the delegates to the Third World Power Conference which is now being held here

Placing the raw tube in the curing mold. This tire worker gives the tubes the same treatment his co-workers give tires; They are cured in a watch-case mold for the required length of time at the proper heat. Naturally tubes take less time than tires because they are single thickness.

Putting tire into curing mold. From the vacuum expander, the potential new truck tire is taken to this "watch-case" curing mold in which it is baked under high heat and pressure for a long time. The exact time and temperature varies with the type and size of tire. The airbag inside the carcass is filled with live steam during this process so that heat is added from both inside and out. The mold contains the tread pattern, or design, as well as all markings which will appear on sidewall. Under this heat and pressure the rubber turns semi-liquid, and flows into every crevice, completely bonding the rubber processed fabric carcass to the cushion, the cushion to the tread. After this operation it is now one unit--a complete tire. Firestone (General) Tires, Akron, Ohio
