Abstract : The patent relates to a prepackaged buoyancy system incorporating a hydrazine gas generator between upper and lower portions of a lifting assembly which are separably connected by a fabric airtight bag. When the hydrazine generator produces a gas, the upper portion is caused to separate from the lower portion to produce a gas filled lifting device.
