Title: Exhaust system for IC engines - has damper to produce adiabatic temperature rise to burn off soot in filter
Inventor: DAUDEL HELMUT
IPC: F01N3/023
Filed: 1979-07-31
Abstract: The engine (1) has an exhaust manifold (2) from which a pipe (3) leads to a soot filter (4). There is an exhaust (5) to atmos. from the outlet of the filter. . A damper (6) in the outlet (5) from the filter is controlled by a regulator (7) according to the pressure difference (9,10) across the filter. When sufficient soot has collected the pressure drop rises and the damper is closed. This causes the gases collecting in the filter to rise in temp. adiabatically until they ignite the soot. As soon as it has burnt the pressure difference falls and the damper opens again. This avoids expensive ignition systems.

Title: Polygon effect of continuous moulding bands for foam prods. - is reduced by fluctuating speed of driving polygonal wheels
Inventor: KLIER UDO DIPL ING
IPC: B30B5/06
Filed: 1980-08-18
Abstract: A double endless band assembly for the continuous prodn. of foamed plastics composite elements comprises bands each made from a series of plates driven and guided around polygonal wheels. A constant speed drive (13) for the polygonal wheels (8) transmits the motion to the polygonal wheels in such a manner that the endless band (6) moves at virtually uniform speed. Pref. each polygonal drive wheel (8) has keyed to it, a polygonal driven wheel (10) possessing the same number of sides; each corner of this polygon has a chain tooth (11) which can be engaged by the teeth (12) of a finely divided drive chain (12) driven by a constant-speed, circular wheel (13). The fine divisions of the chain (tK) constitute a whole number fraction of one side of the driven polygon (10). With this arrangement, a polygon possessing a comparatively small number of fairly large sides, and consequently continuous bands composed of large plates, can be used since the drive cancels out the 'polygon' effect.
