Patent number: 7308903Abstract: A pressure relief device is provided. The pressure relief device includes a sealing member and a low-pressure support member that is adapted to provide support to the sealing member when the sealing member is subject to a certain pressure differential. The low pressure support member includes an annular flange and at least one supporting projection. A cutting element is adapted to puncture the sealing member when the sealing member is subject to a predetermined pressure differential. The pressure relief device may further include a high pressure support member and safety heads forming a pre-torqued assembly. The supporting projection may optionally include an area of weakness either wholly within or on the periphery thereof.Type: GrantFiled: January 4, 2006Date of Patent: December 18, 2007Assignee: BS&B Safety Systems LimitedInventors: Mitch Rooker, Greg Klein, Charlie Beair, Geof Brazier

Patent number: 6494074Abstract: An improved rupture disk assembly and methods and apparatuses for forming a rupture disk are disclosed. The rupture disk assembly includes a rupture disk having a flange connected to a dome-shaped rupturable portion by a transition area. The rupturable portion includes a structural apex formation at or near the apex of the dome and is configured to rupture when exposed to a fluid having a predetermined pressure. Preferably, a safety member is disposed adjacent the rupture disk. The safety member includes a hinge about which the disk bends when the disk ruptures. The present invention is also directed to an apparatus and method for consistently, accurately, and repeatably forming a structural apex formation in a rupture disk before the formation of to the rupture disk dome, during the formation of the rupture disk dome, and after the formation of the rupture disk dome.Type: GrantFiled: March 21, 2001Date of Patent: December 17, 2002Assignee: BS&B Safety Systems, Inc.Inventors: Donall Cullinane, John Daly, Stephen Farwell, Greg Klein, Barry Lowe, Mitch Rooker, John Tomasko, Geof Brazier

Patent number: 6178983Abstract: An improved rupture disk assembly for a pressure relief system is disclosed. The rupture disk assembly is sealed between an inlet support member and an outlet support member, each of which define a central fluid pathway. A rupture disk that includes a flange connected to a dome-shaped rupturable portion by a transition area is sealed between the support members. The rupturable portion may include an indentation positioned at the apex of the dome and a score line having a first and a second end. A safety member that has a hinge including a knuckle and a tongue is positioned between the rupture disk and the outlet support member. The knuckle extends downwardly into the dome and extends laterally across the dome to a point that is inside the area circumscribed by the score line or inside the area circumscribed by an arc connecting the two ends of the score line.Type: GrantFiled: May 13, 1999Date of Patent: January 30, 2001Assignee: BS&B Safety Systems, Inc.Inventors: Donall Culliinane, John Daly, Stephen Farwell, Barry Lowe, Mitch Rooker, John Tomasko
