| 20120037641 | Pressure Vessel Shear Resistant Boss and Shell Interface Element - A pressure vessel has a composite shell; a boss defining a port in the composite shell and having a neck; and an interface element disposed between the composite shell and the boss. The interface element is neither bonded to the composite shell nor to the boss, thereby allowing for movement between the interface element and the composite shell and allowing for movement between the interface element and the boss. The interface element further includes a neck disposed adjacent the neck of the boss. | 02-16-2012 |
| 20120011843 | Shape Memory Alloy Trigger for Pressure Relief Valve - This disclosure describes an apparatus having a valve and an elongated shape memory alloy element. The valve has a lever in a first position, whereby the valve is closed. The elongated shape memory alloy element has a first end connected to the lever. The shape memory alloy element has been strained to have a first length, wherein exposure of at least a portion of the shape memory alloy element to a temperature at or exceeding its austenite transformation temperature causes the shape memory alloy element to shorten to a second length, the second length being less than the first length, thereby causing the first end of the shape memory alloy element to pull the lever to a second position, whereby the valve is opened. | 01-19-2012 |
| 20110303681 | Pressure Vessel Boss and Liner Interface - A boss for a pressure vessel has a flange. The flange includes an interior keyway having an inner sidewall and a plurality of bores disposed on the inner sidewall. A pressure vessel includes a main body section and an end section. The end section includes a boss and the boss includes a flange. The flange includes an interior keyway having an inner sidewall and a plurality of bores disposed on the inner sidewall. In another aspect, a pressure vessel includes an outer shell, and inner liner and a boss including a flange with an exterior side and an interior side. The liner is mechanically integrated with the flange via a plurality of anchors, each anchor contacting the flange only on the interior side. A method of forming a pressure vessel includes providing a boss having a flange. The flange has an interior keyway having an inner sidewall and a plurality of bores disposed on the inner sidewall. The method comprises allowing a fluid polymer material to flow into the interior keyway and into the plurality of bores. | 12-15-2011 |
