Todays patent is one of Regipa’s seventeen U.S. patents.
From column 1, Lines 51 through 68:
“One essential object of the invention is to provide an aerostatic
balloon of which the volume can be very large, so as to be capable
of transporting high loads, and of which the gas-retaining
structure can withstand very high overpressures (several hundred
Accordingly it is an object of the invention to provide a
balloon which can be aerostatically steered by varying the gas
Another object of the invention is to increase substantially
the effectiveness of the steering actions (in the vertical direction)
in order to make possible rapid and well controlled changes in
level regardless of altitude.
Another object is to achieve good balloon stability
regardless of altitude and in particular at the upper limit.
Still another object is to make easier the ground-based
balloon launching operations.”
Regipa's patent has already been cited by fifteen
U.S. patents, plus Canadian, German, Japanese, and
