Title: Process and installation to remove pollutants from contaminated soil
IPC: B09C1/06
Filed: 1989-03-20
Granted: 1992-05-27
Abstract: Process for the removal of pollutants from contaminated soil, in which the soil, preliminarily freed from coarse components by sieving or crushing, is subjected to extraction with washing water containing additives, the soil is subsequently separated from the washing water and rinsed with rinsing water, and the rinsing water, by means of a purification process, is freed from the pollutants extracted from the soil. The invention proposes that the extraction process using washing water, which may contain additives, is carried out substantially separately from the single stage or multistage rinsing and sorting process, that prior to the extraction a very fine fraction having a particle size up to 150  mu m, preferably up to 10  mu m, is separated by means of a dry or wet classification process, and that the dried very fine fraction is subjected to distillation at a temperature of 300 to at most 600 DEG C, preferably vacuum distillation at a temperature of 380 DEG C, and purified from organic pollutants and from compounds of cyanide and mercury. The invention further relates to an installation for carrying out the process.

Abstract: The transmission arrangement (3;4;5) for transmitting information items via an electrical power supply network (1;2) contains a resistor (4) which acts on the power supply network (1;2) and can be switched on and off by means of a switch (3). The resistor (4) is a low-inductance thick-film power resistor whose power consumption in pulse operation in the event of short-term loading is of the order of magnitude of at least 100 watts. The resistor (4) is arranged on at least one individual surface of an electrically insulating substrate (9) and its spatial dimensions are at least as large as those of a housing of an electricity meter. Such transmission arrangements are advantageously used for the remote reading of electricity meters. <IMAGE>
