초록

A helium purification system for use with lighter-that-air airships has a catalytic purification stage for removing oxygen from the lift gas, and if desired, a nitrogen removal stage. Impure lift gas is passed through the catalytic purification stage which includes catalytic means for reacting hydrogen and contaminating oxygen entrained in the lift gas to form water and liberate heat energy. The catalytic reaction of oxygen and hydrogen increases the lift capacity of the airship both by removing oxygen from the lift gas which can then be replaced with ad...

청구항

A method of at least periodically increasing the lift capacity of a lighter-than-air airship having at least one lift compartment containing helium to provide lift capacity for said airship which comprises, inducing flow of a portion of the helium from said lift compartment through a confined path, said helium having a reactable mixture of hydrogen and oxygen components entrained therein, said path having disposed therein for contact by said hydrogen and oxygen components a catalytic reaction surface, the flow of said oxygen and hydrogen components in sa...
