Abstract
Abstract A sealed vessel, containing a fire extinguishant or explosive suppressant, has, clamped to the outside of a frangible wall portion of the vessel, a cap-shaped member supporting an explosive line charge arranged around part of a circle and held against the vessel. An electrically actuated detonator is also carried by the cap member for detonating the charge and opening the frangible opening to release the vessel contents into an exit pipe. A layer of explosive suppressant is carried by the cap member to overlie the explosive charge and to suppress the advance of its explosive along the exit pipe.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
90 words
Fluid container apparatus comprising, a vessel defining a normally closed discharge opening, means supported on the outside of the vessel and locating an explosive charge along a line partially encompassing the discharge opening, means supported on the outside of the vessel and locating an explosive detonator in close relationship with the explosive charge for detonating the charge and opening the discharge opening, and means supported on the vessel for holding a layer of explosive suppressant over the explosive charge to suppress advance of the explosive thereof outwardly of the vessel.
Claim 2
Dependent Claim
90 words
Fluid container apparatus comprising, a vessel defining a normally closed discharge opening, means supported on the outside of the vessel and locating an explosive charge along a line partially encompassing the discharge opening, means supported on the outside of the vessel and locating an explosive detonator in close relationship with the explosive charge for detonating the charge and opening the discharge opening, and means supported on the vessel for holding a layer of explosive suppressant over the explosive charge to suppress advance of the explosive thereof outwardly of the vessel.
Claim 3
Dependent Claim
19 words
Apparatus according to claim 1, in which the normally closed discharge opening takes the form of a frangible dome.
Claim 4
Dependent Claim
33 words
Apparatus according to claim 1, in which the means for locating the explosive cHarge and the means for locating the detonator comprise a cap-shaped member which is securable over the said discharge opening.
Claim 5
Dependent Claim
27 words
Apparatus according to claim 3, in which the means for holding the explosive suppressant comprises a further cap-shaped member which is fixed over the first-mentioned cap-shaped member.
Claim 6
Dependent Claim
63 words
Apparatus according to claim 1, in which the vessel contains an explosive suppressant under pressure, the said support comprising a removable cap member securable over the discharge opening externally of the vessel, the cap member also carrying the detonator which is electrically actuatable for detonating the explosive charge to open the discharge opening and allow release of the explosive suppressant from the vessel.
Claim 7
Dependent Claim
39 words
Apparatus according to claim 5, in which the cap member has inner and outer walls, the explosive charge being supported on the inside of the inner wall, and the layer of explosive suppressant being held between the two walls.
Claim 8
Dependent Claim
84 words
Apparatus for opening a sealed container, comprising a support which holds a linear explosive charge, arranged to partially enclose an area, and which also holds an electrically actuatable detonator for exploding the charge with a layer of explosive suppressant supported on one side of the charge and the detonator, and means for attaching the support externally of the sealed container with the opposite side of the charge adjacent the container to open a frangible opening in the container wall when the charge is detonated.
Claim 9
Dependent Claim
84 words
Apparatus for opening a sealed container, comprising a support which holds a linear explosive charge, arranged to partially enclose an area, and which also holds an electrically actuatable detonator for exploding the charge with a layer of explosive suppressant supported on one side of the charge and the detonator, and means for attaching the support externally of the sealed container with the opposite side of the charge adjacent the container to open a frangible opening in the container wall when the charge is detonated.
Claim 10
Dependent Claim
39 words
Apparatus according to claim 7, in which the support is cap-shaped having inner and outer walls, the explosive charge being mounted on the inner wall and the layer of explosive suppressant being held between the inner and outer walls.
Claim 11
Dependent Claim
15 words
Apparatus according to claim 8, in which the cap member is made of plastics material.
