Patent DE-4027569-A1 (DE)
Inventor: BOHMANN DETLEF DIPL ING
IPC: F23N5/04
Filed: 1990-08-31
Abstract: An apparatus for controlling the exhaust gas temperature in heating boilers (10) is proposed, in which boilers the exhaust gases are conducted to the outside by at least one exhaust gas flue (11 to 13) which is provided with heat exchange ribs (17) which cool the exhaust gases. A bypass pipe, which bridges at least a part of the at least one exhaust gas flue (13), is designed as a pipe (18) which can be inserted into this exhaust gas flue and the flow outlet end (20) of which bears an element (23, 24) which changes the flow cross-section depending upon the temperature. With decreasing output of the heating boiler, the exhaust gas temperature at the outlet would cool so that there is a danger of formation of condensates. This is prevented in that the element (23) opens in the event of cooling exhaust gas temperature at the outlet, so that the exhaust gases essentially flow through the pipe (18) with decreasing cooling. This pipe (18) for exhaust gas temperature control can be inserted into heating boilers simply and economically, even subsequently. <IMAGE>

Title: Indigo dyeing installation - has oxidisation of dye by airflow on both sides of fabric at correct temperature
Inventor: VOSWINCKEL GERHARD
IPC: C04B7/02
Filed: 1992-07-19
Abstract: A dyeing range has oxidisation following the indigo vat immersion, by blowing air on to each side of the fabric as it runs through the installation. The fabric passes a warm air channel directed to one side of the fabric, and then another channel at a similar temperature for the other side. The operation is repeated along the installation. The fabric (4) runs continuously (7) between input rollers (24) and output (25). The fabric is immersed (6) in the dye, in the vats (2) and circulated around rollers (5) and through the mangles (3).
