Title: Exhaust gas cleaning unit esp. for diesel engines - has filter tubes of catalytic porous sintered metal
Inventor: ROEHLIG RAINER DIPL ING
IPC: B01D53/94
Filed: 1989-07-12
Abstract: An exhaust gas cleaning unit, esp. for diesel engine exhaust gases, has a housing contg. filter bodies provided with catalytically active materials which reduce the ignition temp. of filtered soot particles and which promote combustion of the soot particles and/or gaseous noxious materials. The novelty is that the filter bodies are formed by pref. parallel running tubular bodies (4) which are closed at one end (6) and which consist of a pervious porous sintered metal consisting (partially) of catalytically active materials. ADVANTAGE - The tubular sintered metal bodies have much higher mechanical strength that ceramic elements, are self-supporting, can be processed as metallic parts (e.g. welded and machined), have high thermal conductivity for rapid attainment of the soot ignition temp. and reduced soot deposit density (thus reducing gas flow resistance), have a large surface for reliable deposition even of fine soot particles, have a rough surface for improved heat conduction and efficiency, are less prone to hot spots, and already contain the requisite catalysts.

Patent DE-4127711-A1 (DE)
Inventor: FRIESINGER GUENTER
IPC: H02G15/34
Filed: 1991-08-22
Abstract: The current supply comprises a bolt (2) which changes into a tube; heat exchanging elements (9) are fitted outside the tube on the bolt (2) and also inside the tube (19). In the transition area (5) from bolt (2) to tube are provided connecting holes (15). The transition superconductor-normal conductor occurs in the bolt (2). The structure of the low-temperature current supply with heat exchanger for heavy currents makes it possible continuously to heat the current supply from below the transition temperature at its cold end to ambient temperature at its hot end without any ice formation in the region of the hot end. This eliminates the need for dry-gas-filled envelopes and expensive additional heating devices. The structure of such a current supply therefore remains simple and clear.
