Patent DE-4026320-A1 (DE)
Inventor: HOHNECKER HELMUT
IPC: B09B5/00
Filed: 1990-08-20
Abstract: Described is a process for biologically decontaminating contaminated materials in a closed circuit by means of microorganisms. The contaminated material is passed into a treatment zone, moistened and treated with microorganisms which will remove the contamination. The waste water arising is collected and used again to moisten fresh contaminated material. In order to accelerate the decomposition of the contaminants, simplify the utilization of the microorganisms used to decompose the contaminants and reduce the cost of using these microorganisms, activated substances in the form of activated sludge are added to the treatment zone. The process is further accelerated and intensified by previously adapting the activated sludge for the decontamination in a bioreactor.
Patent DE-4028299-A1 (DE)
Inventor: SEWERIN PETER DIPL ING
IPC: G01V1/00
Filed: 1990-09-06
Abstract: In the method for locating subterranean pipes, the pipe or the liquid or gaseous medium (14) contained therein is excited mechanically in a pulsed fashion by a vibration generator (22). The pulse propagates on the pipe (14) and in so doing generates in the ground solid-borne sound waves which are transmitted through the ground and reach the surface of the earth (12). The course of the line (36') along which the solid-borne sound waves reach the surface of the earth (12) is determined with the aid of solid-borne sound transducers (24, 26, 28) which detect the solid-borne sound occurring at the surface of the earth. The course of the line (36') is used to determine the position (42) of the surface (12) which, seen in projection, is located on the pipe (14) to be located. The course of the pipe (14) is traced point by point in this way. <IMAGE>
