Title: Total premix blower-assisted catalyst-coated heater
Inventor: HERZOG ELFRIEDE DR
IPC: F24H1/44
Filed: 1997-06-07
Abstract: The combustion chamber (4) is U-shaped with the honeycomb elements (1,3) in the chamber legs (41,43) and element (2) in the chamber crosspiece (42) respectively. The heat exchanger (28) is arranged in leg downstream from the honeycomb elements. The interval (38) between the two walls of the double-walled chamber should be flowed by a cooling medium as also are the tubes (19) which reach into the chamber corner areas and which lie in the radiation cones (16) of the respective honeycomb elements. The leading element in the fuel-gas mix flow direction should only be coated in catalyst on its walls at the outflow end as opposed to the central element whose walls are coated thus at both ends. The walls of the third element are catalyst-coated throughout. Thus 50% of the fuel mix is catalytically converted on the first element (6,13) radiating heat onto the cooled inner wall (22) of tube (12) which is thus de-coupled.

Patent DE-19736752-A1 (DE)
Title: Control circuit for hydraulic brake pump
Inventor: KOHL ANDREAS
IPC: F04B49/10
Filed: 1997-08-23
Abstract: The hydraulic pump in a vehicle brake system is driven by an electric motor (1) linked to the line voltage by an FET (2). The voltage drop across the FET is monitored by a microprocessor (4). If the voltage drop exceeds a set level the controller switches the FET to isolate the pump motor. This switching action is typically 5 msec as compared with up to 100 msec for a mechanical switch and thereby prevents damage to the FET. After switching off the FET the controller switches the FET at set intervals to restore the pump action after momentary blockages. If the pump motors draws current above a set level then the switching action is only repeated for a small number of cycles.

Title: Establishing middle position of armature of electromagnetic actuator for valve
Inventor: STOLK THOMAS DIPL ING
IPC: F01L9/20
Filed: 1997-08-25
Abstract: The procedure establishes the middle position of an armature of an electromagnetic actuator for operating a gas exchange valve. The valve gear incorporates separate opening and closing magnets with an axially sliding armature between them. The armature is held by an upper and a lower pre-tensioned valve spring in the current-free state of the magnets in an equilibrium position between the magnets. The variation of the current consumption or the voltage of the magnets (3,4) is measured during the excitation. The positions of the turning point (21) for the variation curve of the opening and closing magnets are found by an electronic evaluation device and compared. A characteristic value for the middle position is formed from the result.
