Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
A monitoring device for reversible blow-out disc for protecting an installation against overpressure, said monitoring device comprising support means in the installation, the reversible blow-out disc being mounted on the support means in the installation; at least one electrically insulated feedthrough in the support means extending from outside to inside the installation; and at least one electric probe mounted in the feedthrough and extending into the space behind the rupture disc, said at least one electric probe having a protective tube of brittle insulating material.
Claim 2
Dependent Claim
85 words
A monitoring device for reversible blow-out disc for protecting an installation against overpressure, said monitoring device comprising support means in the installation, the reversible blow-out disc being mounted on the support means in the installation; at least one electrically insulated feedthrough in the support means extending from outside to inside the installation; and at least one electric probe mounted in the feedthrough and extending into the space behind the rupture disc, said at least one electric probe having a protective tube of brittle insulating material.
Claim 3
Dependent Claim
197 words
A monitoring device for a reversible blow-out disc for protecting an installation against overpressure in the fluid contained therein, said monitoring device comprising support means in the installation, said disc being mounted on said support means in the installation, said disc being capable of being moved intact through a predetermined region in being flipped over from a first position to a second position when subjected to excessive pressure of said fluid, said disc in said first position having a convex side facing said fluid and in said second position having a concave side facing said fluid, said disc also being capable of being ruptured or detached from its support means in the process of being flipped over from its first position, a first electrically insulated feedthrough in the support means extending from outside to inside the installation, a first electric probe mounted in the feedthrough and extending into the space behind said disc and into said predetermined region, a second electrically insulated feedthrough in the support means extending from outside to inside said installation, and a second electric probe mounted in said second feedthrough and extending into the space behind said disc and beyond said predetermined region.
Claim 4
Dependent Claim
197 words
A monitoring device for a reversible blow-out disc for protecting an installation against overpressure in the fluid contained therein, said monitoring device comprising support means in the installation, said disc being mounted on said support means in the installation, said disc being capable of being moved intact through a predetermined region in being flipped over from a first position to a second position when subjected to excessive pressure of said fluid, said disc in said first position having a convex side facing said fluid and in said second position having a concave side facing said fluid, said disc also being capable of being ruptured or detached from its support means in the process of being flipped over from its first position, a first electrically insulated feedthrough in the support means extending from outside to inside the installation, a first electric probe mounted in the feedthrough and extending into the space behind said disc and into said predetermined region, a second electrically insulated feedthrough in the support means extending from outside to inside said installation, and a second electric probe mounted in said second feedthrough and extending into the space behind said disc and beyond said predetermined region.
Claim 5
Dependent Claim
47 words
A monitoring device as set forth in claim 2, wherein said electric probe comprises means defining a closed electrically conductive protective tube, said tube being of deformable construction so that said tube is deformed when said disc is moved in being flipped over from said first position.
Claim 6
Dependent Claim
18 words
A monitoring device as set forth in claim 2, wherein electrically conductive fluid is contained in the installation.
Claim 7
Dependent Claim
18 words
A monitoring device as set forth in claim 2, wherein said second electric probe is a non-insulated conductor.
