Title: Process for extracting heavy metals from polluted soils, and device for counter-current extraction in such a process
Inventor: KOKEMULLER DETLEF DIPL-ING FH
IPC: B03C1/00
Filed: 1988-01-27
Abstract: 1. Process for the extraction of heavy metals from loaded soils, whereby the earth to be cleaned is subjected to a division into coarse-grained to finegrained earth-particle-fractions and the fine-grained earth-particle-fraction passes through a multistage heavy metal extraction station, where it is saturated with an extraction solution of water and chemicals which dissolve heavy metal, the treated earth-particle-fraction is rinsed and discharged and after repeated use, the extraction solution, loaded with the dissolved heavy metals, is supplied to a further processing stage, characterized by the following steps : a) after a magnetic preliminary cleaning, the magnetic separation of the ferromagnetic or strongly paramagnetic part of the respective fraction is carried out, whereby the magnetic separators are adapted to the grain sizes of the earth-particle-fractions ; b) the earth (1) to be cleaned passes successively through several acid treatment stations (I-V) on a conveyer belt in the form of a band filter (3) which is permeable with regard to fluid but not with regard to particles, within which stations, according to the process of the counterflow extraction, the earth portion passing through is saturated by the acid and the heavy metals contained therein are largely dissolved by the acid, whereby the heavy metal solution is collected by collecting vessels (6) arranged beneath the conveyer belt and, in the counterflow to the conveying direction (f1 ) of the earth, is fed into the respectively preceding acid treatment station or is removed from the collecting vessel (6) of the first acid treatment station (I) for further processing, and whereby within or adjacent to the last acid treatment station (V) the acid heavy metal solution is expelled from the earth portions by means of rinsing water (W) and after this acid wash the cleaned earth is removed ; c) after that the precipitating of the heavy metals from the acid heavy metal solution is carried out with the addition of electrolyte and subsequently the draining of the salt solution is carried out in a draining station (C1), whereby for one thing the deposited drained heavy metal concentrate (IIC) and for another thing the remaining salt water, if necessary for further processing, are discharged at an outlet (C4, C12) respectively, whereby the draining is carried out on a magnetic path, in which the sediment (C5) containing the precipitated heavy metals is supplied, preferably continuously, to a sedimentation zone (C6), within which, apart from the gravitation forces, the magnetic forces of a strong gradient magnetic field (C7) act on it, with the result that the magnetizable particles contained in the sediment are driven in the direction of increasing magnetic field strength and are compressed into a sediment cake (C8), which is conveyed by means of a discharge zone (C9) out of the region of the gradient magnetic field to the outside.

Abstract: In grinding machines which have a rotary backing plate with an abrasive disc detachably fastened thereto, the abrasive disc is held on the one hand by a central fastening element, which only has the task of preventing radial displacement of the abrasive disc relative to the backing plate, and on the other hand by an adhesive coating which only serves to prevent the abrasive disc from slipping relative to the backing plate in the peripheral direction of the backing plate, the adhesion of which adhesive coating, however, is not sufficient to hold the abrasive disc in place on the bearing surface of the backing plate without the centring action of the central fastening element. The combination of a centring element with an adhesive coating producing a frictional connection permits simple exchanging of the abrasive discs and at the same time guarantees faultless function of the grinding machine. <IMAGE>

Abstract: Une chambre de combustion pour un moteur de turbine à gaz comprend des réseaux de passages de refroidissement des parois d'enceinte de la flamme, passages qui sont dirigés au centre d'orifices d'admission d'air séparés situés dans les zones de combustion ou de dilution. Chacun des passages débouche dans son orifice d'admission d'air correspondant, toute augmentation du flux de refroidissement pouvant ainsi être utilisée sans qu'il y ait perte de combustion ou de dilution. Les réseaux sont sérrés les uns contre les autres ou s'entrecroisent afin d'assurer une bonne couverture des parois. Cette construction s'applique en particulier à la partie des parois de tête de l'enceinte de la flamme et est destinée à résister à la fatigue thermomécanique qui se produit dans les parois de tête laminées.

Abstract: The invention concerns a new type of base plate for working models and a process for manufacturing working models, in particular for dentistry, in which metal or plastic pins (2) are anchored in a base plate (1) or are monolithic with the base plate. The pins (2) subdivide the dental mount (15) - after the latter is sawn - into various working models in which the saw notches (21) are preferably placed in the region of the impressions (20). This obviates the complicated and costly production of individual bores in the base plate.
