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: 6491055Abstract: A pressure relief apparatus includes a valve having a body. A shaft is rotatably disposed in the body and has an exterior end extending through the body. A plug, which may contain an internal passageway, is mounted on the shaft and is disposed in the fluid flowpath. The body is engageable with the system to expose the plug to the pressurized fluid so that the pressurized fluid acts on the plug to exert a torque on the shaft which is offset from the center line of the plug. The apparatus further includes a linkage assembly configured to translate the torque exerted on the shaft into an output force. A release device, such as a buckling pin or a magnet, is connected to the linkage assembly and is configured to release the shaft when the output force exceeds a predetermined limit. Preferably, the linkage assembly is adjustable to vary the magnitude of the output force corresponding to a given torque.Type: GrantFiled: September 25, 2001Date of Patent: December 10, 2002Assignee: BS&B Safety Systems, Inc.Inventors: Geof Brazier, Arthur Dubbeldam, Peter Dubbeldam, Michael Hitz

Patent number: 6484742Abstract: A cartridge assembly for a valve is disclosed. The cartridge assembly includes a cartridge containing an activation component. The cartridge and activation component are configured to be replaceable as a unit. The activation component prevents the valve from either opening or closing until either a predetermined pressure is exerted on the valve or a predetermined temperature is experienced by the activation component. The cartridge may include any of a variety of activation component types, such as buckling pins, tensile pins, shear pins, springs, or fusible alloys, either individually or in combination to control the valve opening or closing.Type: GrantFiled: March 30, 2000Date of Patent: November 26, 2002Assignee: BS & B Safety Systems, Inc.Inventors: Geof Brazier, Arthur Dubbeldam, Peter Dubbeldam

Patent number: 6446654Abstract: A pressure relief device for a sealed system is provided. The device includes a negative pressure support that is engageable with the system. A seal is disposed between the support and the system such that a negative pressure differential created in the system acts on the seal to move the seal away from the negative pressure support. A wire connects the seal to the support. The wire is configured to break, thereby releasing the seal, when the seal is exposed to a negative pressure differential having a predetermined level. The device may also include a positive pressure support disposed between the seal and the negative pressure support. The positive pressure support prevents the seal from releasing until the system experiences a positive pressure differential of a predetermined level. The device may also include a sensor that indicates when the seal has released.Type: GrantFiled: November 26, 2001Date of Patent: September 10, 2002Assignee: BS&B Safety Systems, Inc.Inventors: Geof Brazier, Greg Klein, John Nguyen

Patent number: 6431196Abstract: A pressure relief device with a permanently attached rupture disk is disclosed. The pressure relief device includes a valve body. The valve body includes an inlet and an outlet defining a flow passage therebetween. A valve mechanism is housed in the valve body and is movable between a closed position where it blocks the flow passage and an open position. A rupture disk configured to burst when exposed to a predetermined pressure is provided. The rupture disk is permanently attached to the valve body to prevent the pressurized fluid from flowing through the flow passage until it bursts. Permanently attaching the rupture disk to the valve body makes them a compact unit to be replaced and discarded together. The rupture disk may be permanently attached to the valve body by welding, soldering, brazing, crimping, or adhesive bonding.Type: GrantFiled: April 7, 2000Date of Patent: August 13, 2002Assignee: BS&B Safety Systems, Inc.Inventors: Geof Brazier, Arnold Mundt
