Abstract: A stand for supporting a pressure vessel includes a body having an upper wall and a sidewall extending downwardly from the upper wall, an aperture defined in the upper wall configured to permit passage therethrough of a fluid conduit, the fluid conduit being in fluid communication with the pressure vessel, and a locking element provided in connection with the body configured to engage the fluid conduit when in a locked position to inhibit removal of the stand from the pressure vessel.

Abstract: A sensor for detecting the presence of a liquid. The sensor includes a housing having a concave upper surface, a concave lower surface, and a peripheral wall connecting the upper surface and the lower surface, the wall extending above the upper surface and below the lower surface. A plurality of apertures are formed in the wall. A plurality of electrically conductive members extend above the upper surface and below the lower surface and are separated from one another by a gap in which a liquid can accumulate. The electrically conductive members are configured to generate an output signal when a conductive liquid comes into contact with the electrically conductive members and bridges the gap. An output connector is coupled to the plurality of electrically conductive members and is configured to carry the output signal.

Abstract: A pressure vessel is disclosed which includes a lower metallic dome having a lower rim portion, and an upper metallic dome having an upper rim portion, a plastic liner disposed within the upper and lower metallic domes, a metallic band disposed between the plastic liner and the upper and lower metallic domes proximate the respective rim portions thereof, and an insulating material disposed between the metallic band and the plastic liner, the metallic band and insulating material protecting the plastic liner from elevated temperatures when the upper and lower rim portions of the metallic domes are welded together. A method of fabricating the pressure vessel and a connector for assembling the pressure vessel are also disclosed.
