Abstract: Water-containing inorganic waste materials, originally in loose form, and which contain water-soluble components capable of reacting with each other are mixed and then compacted at a pressure sufficient to reduce the space, volume between the particles of material, cause the reduced space volume to become filled with water and the reactive components to react.

Abstract: Arrangement for covering the surface, which may be inclined, of loose material, in particular earth or waste dump material, comprising a sealing course which is provided with a top fill. In order to improve the adhesion between the sealing course and the top fill, a rough layer is arranged on the sealing course, on top of the rough layer an adhesive non-woven fabric, which cooperates with the rough layer in an adhesive manner, and on top of the non-woven fabric a retaining mat, which bonds with the top fill. The adhesive non-woven fabric and the retaining mat may be a known geotextile drainage layer which, when reversed, is used for a standard drainage arrangement.

Abstract: A waste dump of a standard dump class is covered with at least one waste layer of a lower dump class having a correspondingly lower hazard potential. Furthermore, at least the outer waste layer is provided with a surface-sealing system. Particularly good encapsulation of hazardous wastes is achieved if the latter are covered with other waste layers where the dump class decreases in an outward direction, so that each waste layer is enclosed by a waste layer which lies on top and is of a lower dump class. In this way, waste dumps having a high hazard potential can be reliably enclosed for a long time and isolated from the environment at less expense than in the past.

Abstract: The accumulated waste is pressed under high pressure to form blocks or boards having high strength, low elutability and low permeability, then packed in film individually or in stacks in a dust-tight and water-tight manner and deposited in this form on a dump like building bricks. The process can be used universally for all waste which is available as bulk material and has no coarse components, such as stones, metal pieces and the like.

Abstract: In an operating dump, intermediate sealing layers which are provided with a drainage layer are applied for the production of a multibarrier system to prevent the penetration of seepage water, the seepage water which is collected in the drainage layer being removed and fed to a disposal system. Plastic films or sheets overlapping in the form of roofing tiles or laid as webs have proved suitable as an intermediate covering.

Abstract: To reduce the axial length of distributor-breaker assemblies and to provide for reliable placing of a second upright bearing for the distributor shaft, a holding plate to which a bearing is floatingly attached is clamped in the distributor housing by means of a claw clamp, tightened by a transverse plate against itself and against a shoulder formed in the inner side wall of the distributor, the claw clamp being formed as a partly circumferential ring seated in a groove of the distributor.

Abstract: To provide an easily manufactured ignition distributor in which two bearings support the distributor shaft, the lower bearing is molded or otherwise secured into the housing structure, whereas the upper bearing is supported on a transversely extending support member, typically a support plate which is seated within the housing, for example bearing against a shoulder, against seating lugs, or the like, so that the entire ignition distributor structure can be constructed with small compact size.
