Abstract: A bus bar current interruption device comprising a casing, providing an enclosure, and a bus bar arrangement. The bus bar arrangement is arranged to extend through the enclosure and comprises a first terminal end portion and a second terminal end portion, each of said first and second terminal end portions arranged outside of the casing. The bus bar arrangement further comprised a first fuse portion and a second fuse portion arranged in the enclosure. The casing comprises an exhaust opening configured to allow escape of vapor from the enclosure. The exhaust opening is fluidly connected to an exhaust chamber or conduit formed by the casing or attached to the casing.

Abstract: A method of populating a store with information identifying user devices capable of communicating in a communications network, includes establishing a communication event from an initiator device to a recipient device via the communication network using information identifying the recipient device; receiving from a user of the initiator device a selection signal indicating that said information identifying the recipient device is to populate the store; and transmitting said information identifying the recipient device from the initiator device to the store via the communication network.

Abstract: A method of updating a data record stored in a data store with information supplied by at least one of a plurality of users of a communication network includes storing a communication identifier in association with the data record; providing information to update the data record from a user together with a communication identifier associated with the user providing the information; and comparing the identifier stored in association with the data record to the communication identifier associated with the user providing the information. If the information is the first type of information, the data record is updated with the information only if the identifier associated with the user providing the information is the same as the identifier stored in association with the data record and if the information is the second type of information the data record is updated with the information.
