Patent DE-4228966-A1 (DE)
Inventor: TEUFERT FRIEDRICH
IPC: B01D11/02
Filed: 1992-08-31
Abstract: The invention concerns a process for the decontamination of solid materials, in particular earth, by washing, in several stages, pre-screened particles with water and surface-active agents. The washing process is characterized by a first stage in which the pre-screened particles are batch-processed in a mixer (20) with warm water, saturated steam and surface-active agents and then transferred to a buffer tank (30), and by a second stage in which the particles are washed continuously, with the addition of additional water, in a washing drum (40) and the solids precipitated. The particles are rinsed, if necessary, in a screw conveyor (50). The water is removed mechanically (74) from the sludge precipitated from the aqueous phase in the previous stage and the sludge dried by heating.

Title: Restoring reinforced concrete by electrolytic removal of chloride ions - using electrolyte with resistance not negligible compared with that of concrete to reduce decomposition of water caused by varying thickness
Inventor: ROSE KARL DR
IPC: C04B41/53
Filed: 1992-09-01
Abstract: In the restoration of reinforced concrete (I) by applying an electrical potential to remove Cl ions, the novelty is that an electrolytic material (II) is applied, the resistance of which is not negligibly small w.r.t. that of (I). USE/ADVANTAGE - The process is useful for restoring (I) treated with thawing salt. The use of (II) overcomes problems caused by variations in the thickness of (I) over the steel reinforcement, where normally Cl ions are removed more effectively in thin regions than thick ones. Attempts to counteract this by increasing the voltage increases the decomposition of water and transport of OH ions which is detrimental to (I) in the affected areas, and increases H2 formation.

Abstract: A fence is composed of steel lattice mats (M1, M2) which in turn are composed of horizontal (H1, H2, H3, H4) and vertical rods (V1, V2) soldered at their intersections, forming meshes of any desired sizes. The fence is formed by positioning two adjacent steel lattice mats (M1, M2) in their set position according to their height and mutual distance by means of special connecting members (K1) made of steel or plastics. Such a fence connecting member (K1) has recesses (A11, A12, A13, A14) for enclosing the vertical rods (V1, V2). The recesses (A11, A12, A13, A14) partially extend up to the middle of the clamping material. The reduced flexural resistance of the fence connecting members (K1) in the area of the recesses (A11, A12, A13, A14) is compensated by arranging the recesses obliquely to the plane of the mats or by horizontal rods (H1, H4) which extend beyond the vertical rod (V1, V2) at the edge of the mat and which thus form a support for the various areas of the fence connecting members (K1). The fence connecting members may be alternatively set at opposite positions on different horizontal planes or may be superimposed on a horizontal plane.
