Title: Method for regulating the furnace in incineration plants, in particular in refuse incineration plants
Inventor: MARTIN JOHANNES JOSEF EDMUND
IPC: F23N5/08
Filed: 1995-08-08
Abstract: To detect a regulating quantity which is directly proportional to the combustion temperature, an infrared measuring device in the form of an infrared pyrometer is provided in the descending waste gas flue of an incineration plant and measures the temperature of the waste gases. The influence of radiation from the glowing fuel bed or the flame is excluded by arranging this measuring device in the descending waste gas flue. The temperature-dependent regulating quantity which is determined in this way can be used directly or indirectly to influence the combustion process. In a preferred application, the temperature-dependent regulating quantity serves to influence the supply of fuel and the speed of the combustion grate, while a regulating quantity derived from the mass flow of steam serves to influence the supply of primary air.

Patent CA-2192402-A1 (CA)
Inventor: MISKA RICHARD A
IPC: H04Q3/66
Filed: 1996-12-09
Abstract: A method and apparatus for transmitting signals at different rates  between  an  originating  device  and  a destination device.   The originating device generates a communication   signal,   including   routing   data,  for transmitting the communication signal at a native rate associated with the originating device.  The communication signal is received by a switch which analyzes the routing data  of  the  signal  to  identify  transmission  rates recognizable by the destination device and, if necessary, a transmission path for routing the signal across a backbone network at the native rate.   The system then determines whether to re-encode the signal for direct transmission at a different rate recognizable by the destination device, or to maintain the signal at the native rate for transmission either directly to the destination device or across the backbone network.   The signal is then transmitted.   A destination switch at the destination end analyzes  the communication signal to determine the final destination point; if necessary, it re-encodes the communication signal for transmission at a rate which is recognizable by the final destination point, and then transmits the signal to the final destination.
