Abstract
A storage system for a combustible gas comprises a collapsible container selectively connectable to a source of the gas and to a suitable discharge point together with means effective cyclically to produce controlled expansion of the container so as to enable gas to be transferred from the source for storage and to produce collapse of the container to enable stored gas to be discharged.
Claims19
In combination with apparatus which evolves gas durng an operation and releases at least a given quantity of gas suitable for storage through a gas outlet of said apparatus during a portion of said operation, an improved gas storage and discharge system which comprises container means for storing said gas at substantially atmospheric pressure, said storage means comprising
- collapsible container means dimensioned to hold substantially said given quantity of said gas suitable for storage,
- conduit means between said gas outlet, said collapsible container means, and a discharge point,
- valve means associated with said conduit means for selectively connecting said container means to said outlet and to said discharge point,
- said valve means being operable to continuously connect said container means to said outlet only so long as said gas suitable for storage is being released through said outlet, and
- additional means operable other than by the pressure of the gas in said outlet and in said conduit means to cause continuous expansion of the container so as to permit gas to be continuously transferred from said outlet for storage in said container while said gas suitable for storage is being released through said outlet, said additional means including means to cause contraction of said container to enable stored gas to be discharged from said container to said discharge point.
In combination with apparatus which evolves up to a given quantity of gas during an operation and which releases said gas through the outlet of said apparatus, a gas storage and discharge system which comprises container means for storing said gas at substantially atmospheric pressure, said storage means comprising
- collapsible container means dimensioned to hold substantially said given quantity of gas,
- conduit means connecting said gas outlet to said container means,
- valve means in said conduit means for selectively connecting said container means to said outlet during evolution of said gas and to a suitable discharge point other than said outlet at a time when gas is not being evolved, said valve means being adapted to continuously connect said container means to said outlet so long as said gas is evolving, and
- additional means operable independently of the pressure of the gas in said outlet and in said conduit means to cause continuous expansion of the container so as to permit gas to be continuously transferred from said outlet for storage in said container during the time when said gas is being evolved by said apparatus, said additional means including means to cause contraction of said container to enable stored gas to be discharged from said container to said discharge point at said other time.
A system for the storage of gas derived from apparatus which evolves at least a given quantity of gas during operation, the system comprising container means for storing said gas at substantially atmospheric pressure, said storage means comprising a collapsible container dimensioned when expanded to hold substantially the given quantity of gas, conduit means for transferring gas from said apparatus to said container, conduit means for transferring gas from said container to a point for discharge of the gas, valve means in said conduit means for selectively connecting said container to said apparatus and to said discharge point, the container being sealed into a non-collapsible housing, and reversible low pressure air moving means connected between said housing and ambient atmosphere for expanding said container for storage of said gas other than by the pressure of evolved gas by removing air from the housing, and for collapsing the container to discharge gas from the container to said discharge point, by moving air into the housing.
