Title: Heavy oil engine with bowl-in pistons
Inventor: SCHACHT HANS-JUERGEN DIPL ING
IPC: F02B23/06
Filed: 1987-08-24
Abstract: The known form of the combustion chamber of a heavy oil engine with bowl-in pistons with a mushroom-shaped insert, adapted to the recess, as <<hot spot>> can be further improved for economical but residue-free combustion, even in the partial load range, in that the mushroom-shaped insert is provided with a conical elevation, turning it from a mere ignition aid into a formation diverting the fuel jets in a circular fan shape. In design embodiments, the countersurface of the piston in the cylinder cover is also used for a further improvement of the mixture formation and combustion by means of a form specially adapted to the conical elevation or by the use of a flanged bush enclosing the injection nozzle.

Title: Scrapers for rotating edge screen drums
Inventor: BACH VOLKER
IPC: B01D33/073
Filed: 1988-02-06
Abstract: Fixed scrapers of edge screen drums cannot prevent the screenings from jamming at the drum periphery and not being able to be scraped off. The novel scraper device contains a plurality of star-shaped scraper strips arranged about an axis of rotation, a new scraper strip being swung into the scraper position on each drum rotation and the departing strip discarding the screenings backwards. The strip engaging at an obtuse angle detaches the jammed screenings faultlessly and then peels them off.
