摘要： Apparatus and methods for protecting process equipment from a fire and/or an explosion are provided. In particular, the apparatus and methods utilize Seebeck sensors or thermoelectric generators to detect the propagation of a flame front or deflagration wave within the process equipment. Upon detection of the deflagration wave, the system controller activates mitigation apparatus which may be in the form of a chemical suppressant or isolation valves in order to protect the process equipment from damage.

摘要： A reverse-acting rupture disc (10) having a laser-defined reversal initiation feature (16) is provided in the bulged section (12) of the disc. The reversal initiation feature comprises at least a first lased area (22) that has a reduced thickness relative to rest of the bulged section. A second lased area (24) 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 (40) 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 (56).

摘要： The invention provides an optical burst switch in an Optical Burst Switched (OBS) communication network, said optical burst switch comprising means for monitoring and maintaining mesh of virtual optical paths from a communication node to a plurality of other communication nodes, arranged in a ring network, enabling traffic data to be transmitted and/or received between nodes via a physical optical path. The switch also provides means for sending a data packet probe on a virtual path from a node to each other node in the OBS communication network, wherein data packet probe information received at said switch provides information of availability of the physical optical path for sending traffic data between nodes. The switch can be configured such that the rate at which this path monitoring is scheduled guaranteeing less than 50 ms protection switch in the event of monitoring a failed or degraded path.
