Granted: 1999-01-26
Abstract: A thermally activated relief device (50) which resists extrusion-related failures even at high pressures and yet reliably activates to relieve pressure in a vessel and to prevent a catastrophic pressure rupture of a vessel is provided.  The thermally activated relief device (50) includes a (52) body having an inlet (54), an outlet (56), and a fluid flow passage (58) communicating with the inlet and outlet.  The body further includes a fluid escape passage having a (60) member therein which is porous to gases and liquids but not to solids.  A plug (62) of a fusible material which melts at a predetermined temperature is positioned adjacent to the porous member and normally seals the fluid escape passage.  A piston (64)  is normally biased into a sealing relationship with the inlet, but, when the fusible plug melts, moves upwardly to open the flow passage and relieve fluid pressure.

Title: Method and apparatus for sealing and transferring force in a wellbore
Inventor: LOUGHLIN MICHAEL J
IPC: E21B33/127
Filed: 1993-10-04
Granted: 2004-07-20
Abstract: A wellbore (1) is at least partially obstructed with a partition or obstruction member (5). A fluid slurry of an aggregate mixture of particulate matter is pumped into the wellbore adjacent the partition or obstruction member. The aggregate mixture of particulate material contains at least one component of particulate material, and each of the at least one particulate material components has an average discreteparticle dimension different from that of the other particulate material components. Fluid pressure then is applied to the aggregate material, and fluid is drained from the aggregate material through a fluid drainage passage in the partition or obstruction member. The fluid pressure and drainage of fluid from the aggregate mixture combined to compact the aggregate mixture into a substantially solid, load-bearing, force-transferring, substantially fluid-impermeable plug member (11), which seals a first wellbore region from fluid flow communication with a second wellbore region. Theplug member is easily removed from the wellbore by directing a high-pressure fluid stream toward the plug member, thereby dissolving or disintegrating the particulate material of the plug member into a fluid slurry, which may be circulated out of or suctioned from the wellbore.

Patent CA-2190694-C (CA)
Inventor: VIEGAS HERMAN H
IPC: F25D29/00
Filed: 1996-11-19
Granted: 2002-09-17
Abstract: Both an apparatus and method are provided for vaporizing a liquid cryogen and super heating the resulting vapor into a heated gas. The apparatus includes a combustion-type heat source which may burn a fuel such as propane that generates water-containing combustion gases, and a vaporizer coil having an inlet conduit for receiving a flow of a liquid cryogen, such as liquid carbon dioxide, and an outlet conduit for expelling vaporized cryogen. An annular casing surrounds but is spaced apart from the vaporizer coil. The casing isolates the vaporizer coil from contact with water-containing combustion gases generated by the heat source, thereby preventing the formation of unwanted water and ice on the coil, while at the same time transferring heat from these gases to the coil by thermal radiation. A superheating coil is serially connected to the vaporizer coil to further heat the vaporized cryogen. Both the vaporizer coil and super heater coil are compactly configured and disposed within a heat-insulating housing for minimizing heat losses. The device is particularly well adapted for use as a defroster or a heater in a mobile cryogenic refrigeration system.
