IPC: B02C4/28
Filed: 1992-08-24
Abstract: In the pressure treatment of granular material in the roller gap (15) of a two-roller machine, air (17) is pressed out of the bulk material and flows, counter to the material flow, through the bulk material and loosens the latter in the process. As a result of a widening of the lower part of the material feed shaft (12), the bulk material can form a slope (16) and is conveyed in a free flow to the roller gap (15), unhindered by the air flowing towards it and by friction against the shaft wall. <IMAGE>

Patent DE-4233315-A1 (DE)
Inventor: ROTTMAR WERNER
IPC: G01F23/22
Filed: 1992-10-05
Abstract: The novelty concerns a device for securing a housing of a measurement detector containing electronic circuits and connectors. Such measurement detectors are secured by means of a screw-in component in the wall surrounding the measuring medium. Here they can adopt a position depending on the function, in which it is very difficult to fit the connecting lines to a control room remote from the point of measurement. The housing is therefore to be movable axially symmetrically to the screw-in component. The proposed solution is for the releasable connection between the housing and the screw-in component to take the form of a single, easily accessible screw passing through a clamping plate and projections engaging in a groove in the screw-in component. The position of the clamping plate can be altered by tightening and loosening the screw in such a way that a clamped joint is produced between the projections of the clamping plate and the groove of the screw-in component in which the electronics housing is secured in any axially symmetrical position in relation to the screw-in component.

USE/ADVANTAGE - Provides a simple process for separating the components of a VPE/metal joint or composite; the process can be operated as a combined sepn. and sorting process (contrast processes based on complete dissolution). and the swollen VPE is easily sepd. from the swelling agent and recovered. The alkane gives rise to no unwanted side reactions or soiling, and is simple and safe to use.

Title: Process for the rehabilitation of contaminated soils, based on leaching by means of plants with recovery of valuable materials
Inventor: MEININGER SIEGFRIED
IPC: A62D3/00
Filed: 1993-02-10
Abstract: For the rehabilitation of contaminated soils, in particular in the case of pollution with harmful materials over large areas, a process and equipment are envisaged, wherein the soils are initially relieved by planting with plants suitable for absorbing metals and other harmful substances in one or more steps in the decisive range. The biomass thus obtained is carbonized, so that it becomes possible to burn the organic harmful substances together with the carbonization gas and/or to process the metals and heavy metals in the course of a corresponding processing of the solids in an electrolysis and, if appropriate, in preceding steps to such an extent that the residual materials which then remain can be taken to beneficial uses, without a hazard to the environment. The metals and heavy metals are recovered separately in the electrolysis and can then even be returned into the cycle. <IMAGE>
