Title: Installation for decontaminating granular material - by heating material to gasify contaminating liq.
Inventor: LINDE GERHARD DR ING
IPC: F23G7/14
Filed: 1990-11-27
Abstract: The invention concerns an installation for the thermal decontamination of granular material, especially soil. The material is first passed through a pre-drier (2) which is fitted with a pipe coil (14) in which hot water is circulated.

Title: Plate for heat exchangers - has adjoining plates with holes of different sizes to accommodate burrs on edges of holes
Inventor: REHBERG PETER
IPC: F28D9/00
Filed: 1990-12-21
Abstract: The heat exchanger is constructed from plates mounted side by side with the holes in the plates in line for the through flow of the heat exchanging medium. The plates and the holes in the plates are produced by stamping which leaves a burr on the edge of the hole. - This burr prevents adjoining plates from being pressed close together. This problem is overcome by making the hole (3) in one of the plates larger than the hole in the other plate. The plates are then arranged so that the burred edge of the smaller hole (2) projects into the larger hole. (3pp Dwg.No.2/2)

Title: Method of disposal of household refuse - by separating soft refuse from hard refuse and making compost from soft refuse
IPC: B02C17/00
Filed: 1991-05-06
Abstract: In order to utilise household refuse, the hard refuse is first separated from the soft refuse by a machine (1) which houses a rotating drum (8).
