G08B 21/00

US Classification:

340611, 340626

Abstract:

A burst indicator () for use in a rupture disc assembly () is provided. The burst indicator () comprises a non-electrically conductive material having an outer annular portion () and an inner section () joined to the outer portion by a pair of bridge features (). A circuit comprising electrically conductive segments () is located on the burst indicator () and can be used to monitor the integrity of the rupture disc (). One electrically conductive segment () is located on the outer annular portion (), and another electrically conductive segment () extends across the bridge features () and inner section (). Upon rupture of the rupture disc (), one of the bridge features () carrying an electrically conductive segment () severs thereby opening the circuit.

US Classification:

220 892, 21912169

Abstract:

A reverse-acting rupture disc () having a laser-defined reversal initiation feature () is provided in the bulged section () of the disc. The reversal initiation feature comprises at least a first lased area () that has a reduced thickness relative to rest of the bulged section. A second lased area () may also be provided within the margins of the first lased area. The second lased area has a depth that is greater than the depth of the first lased area. A line of weakness () may be formed in the bulged section that functions to direct reversal of the bulged section toward a particular area of the disc, such as line-of-opening recess ().
