Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
107 words
An explosively actuated valve comprising a body with a passage therethrough which passage provides an inlet and outlet for fluid under pressure, a diaphragm closing said passage to the movement of fluid which is normally rupturable by the pressure of said fluid, a frangible support means positioned on the outlet side of said diaphragm to prevent rupture of said diaphragm, said frangible support means adapted to retain at least one explosively actuated nonrupturing expansion means, said expansion means beinG actuated by an electrical impulse and arranged to expand in contact with said frangible support means whereby said support means is fractured and fails to support said diaphragm.
Claim 2
Dependent Claim
107 words
An explosively actuated valve comprising a body with a passage therethrough which passage provides an inlet and outlet for fluid under pressure, a diaphragm closing said passage to the movement of fluid which is normally rupturable by the pressure of said fluid, a frangible support means positioned on the outlet side of said diaphragm to prevent rupture of said diaphragm, said frangible support means adapted to retain at least one explosively actuated nonrupturing expansion means, said expansion means beinG actuated by an electrical impulse and arranged to expand in contact with said frangible support means whereby said support means is fractured and fails to support said diaphragm.
Claim 3
Dependent Claim
18 words
The valve of claim 1 wherein the material of construction for the frangible support means is tempered glass.
Claim 4
Dependent Claim
19 words
The valve of claim 2 wherein the expansion means comprises an explosive rivet retained in said frangible support means.
Claim 5
Dependent Claim
58 words
An explosively actuated valve comprising a body with a passage therethrough which passage provides an inlet and outlet for fluid under pressure, a diaphragm of tempered glass closing said passage to the movement of fluid, at least one explosive rivet arranged to expand in contact with said diaphragm whereby said diaphragm is fractured and said passage is opened.
Claim 6
Dependent Claim
58 words
An explosively actuated valve comprising a body with a passage therethrough which passage provides an inlet and outlet for fluid under pressure, a diaphragm of tempered glass closing said passage to the movement of fluid, at least one explosive rivet arranged to expand in contact with said diaphragm whereby said diaphragm is fractured and said passage is opened.
