Patent number: 9810333Abstract: A flange adapter is provided for positioning an insert device within a pressurized fluid system. A flange adapter assembly includes a pressure containing boundary and a flange adapter configured to be selectively connected to the pressure containing boundary. The adapter is configured to interchangeably fit a plurality of flange standards for the same nominal size. The adapter may also interchangeably fit a plurality of pressure ratings for the same nominal size. The flange adapter may be manufactured separate from the pressure containing boundary to allow for utilizing less costly material and to increase standardization of safety heads. The present invention also includes a gasket design having multi-flange compatibility for use in pressurized fluid systems.Type: GrantFiled: September 9, 2004Date of Patent: November 7, 2017Assignee: BS&B Safety Systems LimitedInventors: Geof Brazier, Donall Cullinane, John Tomasko

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
