Title: Guidance of a pneumatically sprung axle in commercial vehicles
Inventor: TENGGARA SEMAR-ED DIPL ING
IPC: B60G9/02
Filed: 1993-10-08
Abstract: The proposed control arm arrangement serves for the precise guiding of axles, especially of steered axles in commercial vehicles, the axle suspension being produced by a combination of air and leaf springs. Through a parallelogram arrangement of two longitudinal control arms of equal length per axle half, which control arms pivotably connect the axle beam to the axle mounting, a defined horizontal and vertical guiding of the axle is ensured. Lateral forces occurring are absorbed by a thin-walled, preferably single leaf spring, which is fixed or detachably connected to one of the longitudinal control arms or forms a single integral component therewith. This solution has applications especially in road vehicles which are subjected to a frequent variation of load, for example container vehicles.
Patent DE-4335028-A1 (DE)
Title: Process for extracting heavy metals from polluted excavated earth, mineral demolition material and sludges
Inventor: GIEGOLD WOLFGANG
IPC: C02F11/14
Filed: 1993-10-14
Abstract: Soils, water sediments, sewage sludges and excavated mineral material polluted with heavy metals can be cleaned using acid extraction processes. The cost-determining factor in such processes is generally the acid consumption. Furthermore, environmental pollution can occur due to undesirable side reactions. Therefore, the extraction medium must be optimised so that it reacts as far as possible only with the heavy metals and heavy metal compounds but not with other, acid-soluble compounds. The process presented exploits the fact that the undesirable competing reactions proceed with gas development. The side reaction velocities are decreased by the measures presented.   If the contact time of extraction medium and material to be cleaned is restricted, the selectivity of the extraction medium for heavy metals is improved. This was demonstrated in tests.
