A system and method for transferring compressed gas from a supply point to a delivery point including an ejector, high and low pressure headers, and a plurality of containers that hold compressed gas and are selectively connected to the high and low pressure headers. The ejector uses energy created

A system and method for transferring compressed gas from a supply point to a delivery point including an ejector, high and low pressure headers, and a plurality of containers that hold compressed gas and are selectively connected to the high and low pressure headers. The ejector uses energy created from the high pressure compressed gas to draw residual pressure gas out of the containers. The system and method also both preferably include a control system for controlling compressed gas flow through the system.

An adaptor according to claim 8, wherein the residue limiting means includes a plate-like component adapted to engage with the end face of the spigot portion to form a cover thereon.10. An adaptor for fitting to a threaded opening of a container and adapted to cooperate with a spigot portion of liquid transfer apparatus for filling the apparatus with liquid from the container, the adaptor including: a wall defining a socket portion having an entry adapted to receive therethrough the spigot of the liquid transfer apparatus, an inlet in said wall spaced from said entry for allowing liquid to flow into said socket portion and an outlet in said wall for allowing fluid to flow from said socket portion into the container to which the adaptor is fitted, said fluid outlet being spaced from said inlet and the inner face of said wall being adapted to sealingly engage with axially spaced apart sealing means extending circumferentially around the spigot, one on each side of said outlet to isolate said outlet from said inlet, andsecuring means on said socket portion or operatively connected to said socket portion for securing the adaptor to a threaded opening of the container to which the adaptor is fitted for liquid communication of the socket portion with the container, the securing means being adjacent said entry whereby the adaptor may be secured to the container with the socket portion substantially housed within the container.11. An adaptor for fitting to a threaded opening of a container and adapted to co-operate with another product for the transfer of liquid from the container to or via the other product, the adaptor including; a cap portion adapted to engage with the rim of the container opening;a plurality of circumferentially spaced apart thread engaging components movably connected to and depending from said cap portion and adapted to engage with respective circumferentially spaced portions of the thread about the opening, andadjustment means operatively connected to said thread engaging components and adapted to adjust the position of said thread engaging components radially in and out for engagement with openings of different size.12. An adaptor according to claim 11, wherein the thread engaging components are spaced apart in the direction away from the cap portion whereby they can engage with circumferentially spaced portions of the same thread form.13. An adaptor according to claim 12, wherein the thread engaging components or at least a portion of each of them is flexible towards and away from the cap portion whereby they are self-adjusting to accommodate threads of slightly different pitch.14. An adaptor according to claim 11, wherein the thread engaging components or at least a portion of each of them is flexible towards and away from the cap portion whereby they are self-adjusting to accommodate threads of slightly different pitch.15. An adaptor according to claim 11, wherein the thread engaging components are so made and arranged that the area of contact with the threads of the threaded opening increases as they are adjusted to suit openings of greater diameter so that they can bear a greater tightening force.16. An adaptor according to claim 11, wherein the cap portion has an integrally formed upstanding wall on the opposite side to the thread engaging components, the cap portion having provided therein a socket formed therein, the socket having an entry adapted to receive therethrough the spigot portion or other liquid entry part of liquid transfer apparatus for transferring liquid from one container to another container including:a body defining an elongate liquid storage chamber having a liquid inlet at one end and a fluid outlet spaced longitudinally from said liquid inlet, a
