Abstract: A pivoting, liquid cooled slag door for metallurgical furnaces is disclosed. The slag door can pivot from the top using one or more robust mechanisms that enable the door to be moved into and stopped in any position between a closed position and an open position. The slag door can also incorporate wing walls disposed in close proximity to the sides of the slag door. The wing walls can minimize air infiltration into the furnace when the slag door is in an open position. The slag door can be disposed in close proximity to the hearth of the furnace to eliminate problems associate with conventional slag door tunnels. The slag door can be fitted with a furnace apparatus such as a burner or a lance and can be used to provide access to the interior of the furnace and to control the flow of material out of the furnace.

Abstract: Embodiments of the present invention are generally directed to a system for monitoring a variety of environmental and/or other conditions within a defined remotely located region. Such a system may be configured to monitor utility meters in a defined area. The system is implemented by using a plurality of wireless transmitters, wherein each wireless transmitter is integrated into a sensor adapted to monitor a particular data input. The system also includes a plurality of transceivers that are dispersed throughout the region at defined locations. The system uses a local gateway to translate and transfer information from the transmitters to a dedicated computer on a network. The dedicated computer, collects, compiles, and stores the data for retrieval upon client demand across the network. The computer further includes means for evaluating the received information and identifying an appropriate control signal, the system further including means for applying the control signal at a designated actuator.
