NEW INVENTION WOULD PREVENT TEP EXPLOSIONS
Hindenburg Disaster Might ~ Have Been Averted by Patented Device.
(Copyright, 1937, by Science Service) WASHINGTON, May 14.—A new invention which eliminates. the heed of valving explosive hydrogen by an airship and which might well have prevented the tragic Hin-
denburg disaster has just been granted by the U. S. Patent Office
According to the patent of Wilr helm O. L. Fischer of the Good+ year-Zeppelin Corp. of Akron, the hydrogen, instead of being sent Off into the air where it is a po tential menace from explosion, is converted into harmless water po can be used for drinking, cooking and {even as ballast for an airship. | In the airship proposed in Mr! Fisher’s patent both hydrogen and helium gases are used to obtain] buoyancy, with the hydrogen in relatively small bags completely surrounded by noninflammable helium gas. The hydrogen bags are, completely inflated as the airship is on the ground. The helium bags are only partially inflated to allow | for the expansion of the gas which occurs as the airship rises.
The hydrogen gas expands too, | on rising, but the excess is led off
into a specially shielded burner | |
where it is burned. In the burning it combines with oxygen and forms water. Beside the safety factor, other claims of the new patent are: Less ballast needed, “Jess fresh drinking water need be @mivied, and | elimination of the necessity of con- | densing engine exhaust gases to compensate for the loss of. fuel consumed on a flight. Mr. Fischer also outlined in his patent how the heat obtained from the burning hydrogen can create steam and be used to spin turbines and even the propellers of the airship. The Goodyear-Zeppelin Corp. now holds | the patent through assignment.
