International Classification:

G06F 1730

US Classification:

713201, 707 9

Abstract:

For use during maintenance of wide area networks, a management system is disclosed for distributing security databases to security gates at each maintenance port of each network element. A distributed database manager is provided to instantaneously update the databases and gather from each database transaction records. Central to the distributed database manager is a software program that polls the security databases located at each of the network elements, deposits updated databases, and formats various management reports from transaction records and from device failure records (generated by the program). The software program enables the database manager to communicate with the network elements through either an in-band channel or an out-of-band channel. By shifting authentication of access seekers to security databases resident at each console port, security is maintained even though the network server is not in service. Using existing technology, all communications between the distributed database manager and the security database is in encrypted form.

Abstract:

An explosive release clamp adapted to be opened suddenly by electrical initiation of an explosive charge, and a safety pressure release system for closed vessels such as chemical reactors, high pressure storage tanks, or the like, wherein one or more such clamps are used to secure a main hatch to a reactor vessel. Upon occurrence of an emergency condition such as over-pressure, all clamps are automatically fired simultaneously to release the hatch. A manual override circuit enables firing the clamps in case the hatch must be released without an emergency signal. A test circuit checks the clamps and their associated cabling for electrical continuity, using a current substantially less than that required to fire the clamps.
