Title: Process for conservation of exterior monuments - has series of non destructive tests carried out partic. to identify sulphur dioxide damage
Inventor: HEPPNER FRANZ
IPC: G01N33/38
Filed: 1975-10-18
Abstract: The process for conservation of monuments is esp. suitable in connection with damage caused to stone by sulphur dioxide deposits, but applies also for protection of stone, wood or metal.

Title: Biological treatment of highly concentrated wastes - by intensive aeration developing heat for anaerobic digestion tank
Inventor: SCHREIBER AUGUST DR ING
IPC: C02F3/30
Filed: 1977-08-13
Abstract: In a multi-stage biological treatment of highly conc. waste, e.g. from sugar refineries, preserve factories or animal farms, the first stage uses an enclosed and heated digestion tank.
