Abstract: A plate fin fluid processing device includes active layers, where each active layer includes a fin plate sandwiched between parting sheets so that an active fluid space is defined between the parting sheets. The active layers include an outermost active layer having an inlet and an outlet. A contingent layer body is positioned adjacent to the outermost active layer and includes a fin plate positioned between a parting sheet and a cap sheet. The contingent layer body has a fluid space that is sealed with respect to the atmosphere. A pressure monitoring system is in communication with the fluid space of the contingent layer body. An emergency pressure relief device is configured to release a pressure within the fluid space if a preset pressure is exceeded.

Abstract: A device for distributing a fluid to a processing component includes a vessel having an inlet port for receiving a stream of fluid. A vapor outlet line is in fluid communication with the fluid processing component and has a vapor outlet line inlet in fluid communication with the headspace of the vessel. A liquid outlet line has a liquid outlet line inlet in fluid communication with a liquid side of the vessel and the fluid processing component.

Abstract: Disclosed herein is an adaptive communications network and a method of adapting the network. The network comprises, at least a first and second base station operable to communicate with one another and with a plurality of mobile client platforms (MCPs), at least a first and second MCP, each provided with a communications module, a processing module, and a means of manoeuvring. The first MCP is provided with and operable to execute: a first initial route plan and a first initial communications plan for maintaining a communication link with either of the base stations. Further, the first MCP is operable to collect and transmit first situational awareness data. Similarly, the second MCP is provided with and operable to execute: a second initial route plan and a second initial communications plan for maintaining a communication link with at least one of the base stations, and is operable to collect and transmit second situational awareness data.

Abstract: An audio broadcasting signal disruption sensor and backup program source for providing an alternate audio programming sources in the event of primary-source audio programming failure so as to automatically switch to a backup alternate audio programming source feeding an output audio stream for broadcasting. The system includes monitoring an audio stream from a primary-sources audio programming output, detecting a substantially constant amplitude waveform in the audio stream, determining that the substantially constant amplitude waveform remains of substantially constant amplitude continuously for a threshold period of time, switching the output audio stream from the primary-source audio programming to the alternate audio programming source upon expiry of the threshold period of time, and providing notice of any main-source audio programming failure to administrative personnel.
