A pressure vessel for holding a pressurized fluid such as compressed natural gas ('CNG') includes two end cells and zero or more interior cells. The cell geometry ensures that the cells meet one another at tangential circular surfaces, thereby reducing the tendency of adjacent cells to peel apart. A web secured about the cells includes two sheets that are tangent to the cells. Unused volumes between the cells and the web contain wedges of foam or rubber. A valve provides fluid communication between the interior of the pressure vessel and a pressurized fluid line. The filled weight of one pressure vessel does not exceed the filled weight of a conventional gasoline tank that occupies substantially the same space as the pressure vessel. The pressure vessel may be configured with exterior recesses for engaging conventional gasoline tank straps.

Composite conformable pressure vessel

A method and device for producing a controlled combustion by placing a combustion chamber in communication with a feed chamber that contains a solid propellant/body, introducing at least a portion of the body into the combustion chamber, isolating the combustion chamber from the feed chamber, and igniting the solid propellant in the combustion chamber while the combustion chamber is isolated from the feed chamber.

A joint is disclosed for connecting extruded segments to form a container, such as a pressure vessel for storing liquid propane. In cross section, joint includes a pair of symmetrical tabs, each tab configured at the end of adjacent arcuate outer wall segments. Tabs are configured for contiguous engagement to form a boss having a proximate neck portion and a distal body portion. Joint also includes a retaining member configured at the end of an internal web segment. Retaining member is configured to capture boss. A sealing weld is utilized to seal the adjacent tabs at exposed seam.
