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

other international patents.
