Title: Stabilising bubble layer in gas-liq. sepn. columns - using vertical baffle plates in each deck
Inventor: SCHRAMM ARNO DIPL ING
IPC: B01D3/24

Title: Rotary engine with separable abutment and adjustable valve cam - has cylinder comprising toroidal chamber with piston revolving around chamber in front of pressure wave
IPC: F01C1/46
Filed: 1978-01-19
Abstract: The engine comprises at least one cylinder and preferably several cylinders side-by-side. Each cylinder comprises a toroidal cylinder and has a piston which revolves around the cylinder.

Title: Iron ore direct reduction in shaft furnace - using reduction gas streams to distribute recycled top gas stream throughout furnace
Inventor: PAPST GERO DR ING
IPC: C21B13/02
Filed: 1978-03-11
Abstract: A direct redn. process for iron ore is described in which a top-charged redn. furnace is supplied with hot redn. gas in its redn. zone and the top gases, after steaming and/or enrichment with hydrocarbons, is recycled to the furnace below the position of hot redn. gas supply. The improvement is that, in the lower region of the redn. zone, the rising stream of hydrocarbon-enriched top gases is entrained into various regions of the redn. zone cross-section by a stream of hot redn. gases which varies in direction and/or intensity with time. The method prevents concn. of the rising top-gas stream at the centre of the reactor so that a uniformly high degree of redn. of the core is achieved.

Title: Granulation of sewage sludge - by thickening and moving through dry self-hardening coating material
Inventor: KRIEGER HEINZ
IPC: C02F11/00
Filed: 1978-06-21
Abstract: Sewage sludge is processed to granules for ready dumping by dewatering the sludge from a digestion tower and by thickening it through the admixture of fillers before shaping it to granules. The continuous motion through a recirculated self-hardening dry bonding medium surrounds the granules with a stable protective sheath which is impermeable to water. Such granules can be deposited on dumps without risk that toxic components or infectious germs are washed out and contaminate the water supply.
