Abstract: PROBLEM TO BE SOLVED: To establish communication between two devices via HomePNA network by incorporating a home network filter bridge for connecting a first home network on a first telephone line to a second home network on a second telephone line. SOLUTION: The home network filter bridge 100 is connected between the wire pair of the first telephone line A and the wire pair of the second telephone line B. The first telephone line A supports the first home network consisting of a conventional telephone set 130, a first HomePNA network device 140 and a second HomePNA network device 150 and the second telephone line B supports the second home network consisting of, for example, another telephone set 110 and an xDSL device 120 having a HomePNA networking function. The first and the second telephone lines A and B are connected to a same network interface device.

Abstract: An improved rotary hearth furnace having a cylindrical enclosure containing a radially moving belt for transporting pellets containing metal oxide and carbon is disclosed. One or more oxy-fuel burners preferably having a flat flame shape are positioned so as to provide a mixture of fuel and oxidant to the pellets countercurrent to the direction of the pellets. The oxy-fuel burners are operated so as to provide a pre-determined quantity of oxygen in addition to that necessary for combustion so that the additional oxygen oxidizes the carbon monoxide and hydrogen present in the hot combustion gases. Oxygen injectors may also be used to introduce additional oxygen into the furnace. The additional oxygen is strategically injected into the furnace based on thermodynamic modeling of the furnace so that a substantial majority of the fuel is introduced in a reducing zone so that the reducing zone has a fuel-rich atmosphere while the oxidant is primarily introduced in the heating zone so that the heating zone has a fuel-lean atmosphere.
