-
a first envelope having a first volume; a second envelope contained within the first volume and having a second volume for holding a volume of lifting gas, the second envelope sized to accommodate an expansion of the volume of the lifting gas contained in the second envelope such that the volume of the second envelope expands as the volume of the lifting gas expands; and wherein a portion of the first volume not containing the second envelope decreases with the expansion of the second envelope while the sum of the portion of the first volume not containing the second envelope and the volume of the second envelope remains generally constant. - View Dependent Claims (20, 21)
