Abstract: Disclosed are articles useful as the body of a container for containing gas under pressure, and containers which comprise the articles to which are affixed valves to control the flow of gas out of the container, wherein the articles comprise a hollow container body, having an external surface and having an opening through which gas can enter or leave the interior of the hollow container body; optionally but preferably a layer of fiber-reinforced polymer around the exterior of the container body, and an external layer of elastomer around and sealed to the external surface of the layer of fiber-reinforced polymer if present or else to the cylinder body.

Abstract: Novel cylinder passivation procedures to increase the room temperature stability of gaseous tin deuteride (SnD4) are described. Incorporation of specific organic-containing materials, which when applied onto surfaces of a vessel and/or conduit extending therefrom, can increase the shelf life stability of thermodynamically unstable gases stored within such pretreated vessels.

Abstract: A pressure indicating device for detecting and isolating leakage of toxic and/or pyrophoric gasses from within various packages is disclosed. The device can affix to a user port of a cylinder package. The device has a flexible disc-like structure which is fine tuned to outwardly flex in response to a build-up of pressure of the gas exerted against the disc-like structure. The flexed disc contacts a movable pin and pushes the push outwards from within the device. The outward movement of the pin pierces a paper seal extending over the device, thereby indicating a leak from within the valving of the package. The device withstands the pressure exerted against it, thereby also isolating the leak of the pressurized gas.
