Title: Process for the making inert (inerting) of combustion residues and also natural and industrial sediments
Inventor: EBERIUS ERNST DR
IPC: A62D3/33
Filed: 1989-03-18
Abstract: According to the invention, a process is provided for converting contaminated, in particular by heavy metals, combustion residues and also natural and industrial sediments into a form which can be landfilled (dumped).

Title: Fuel injection pump with engine torque control - has mechanical drive with pneumatic correction for accurate dosing
Inventor: KOERNER WOLF DIETRICH PROF DIP
IPC: F02D31/00
Filed: 1989-09-06
