Inventor: SCHOENBUCHER AXEL PROF
IPC: B09C1/10
Filed: 1992-04-02
Abstract: An on site process for restoration and clearing of contaminated earth mud and water. The contamination, esp. of organic form may be electrically neutral and not or only slightly polarisable. An electric field is applied to the contaminated region (in a known manner). A sound wave field is applied to the same region. Finally in oxidising agent is used within the contaminated region. The oxidising agent may be ionic, nonionic or amphoteric. If need be ozone or organic peroxide can be used. The electric and sound fields can be constant or pulsed. The oxidising agent is in a water circulation cycle through the affected region and operating equipment. ADVANTAGE - The ground mud etc) is not damaged biologically by the process. The sound field raises the permeability of the ground, which holds to concentrate the contamination at the electrodes. The electric field continuity is improved by the sound field.

Title: Process and assembly to generate non-contaminating nitrogen@-steam fog - provides facilitation of visual detection of flow paths at slow speeds
Inventor: BUSSING HARALD DIPL PHYS
IPC: B01F23/10
Filed: 1992-05-08
Abstract: In a process and assembly to generate a non contaminating nitrogen/steam fog to enable visual detection of flow paths, liquid nitrogen is mixed with ultra-distilled water. The liquid nitrogen is dosed and then introduced to the distilled water. Distilled water is pre-heated within a vessel (3) under controlled conditions such that part of the vessel which is not filled by liquid is filled by steam generated from the distilled water. The liquid nitrogen is dosed into the distilled water vapour in vessel (3) from which it is led to the application. The input of liquid nitrogen and the heat applied to the distilled water depends upon the distilled water vapour pressure within the vessel, and the temp. of the emerging nitrogen-steam fog, such that the fog temp. is the same as that of the ambient environment and that the fog moves at slow speed. A suuitable assembly incorporates a heat-insulated vessel (2) for liquid nitrogen (2a) and a vessel for ultra-pure distilled water, an electric heating element (19) for the ditslled water (3a), inlets (9, 22) from the vessel (2) for liquid nitrogen to the vessel (3), a dosing assembly (23) and an outlet pipe for the nitrogen-water vapour fog. A pressure sensor (26) is located in the vapour section of the distilled water vessel. A temp. sensor (27) is located in the fog outlet pipe (24), while a control assembly (28) determines the heat liberated by the heating element (19). USE/ADVANTAGE - Liquid nitrogen and distilled water mixed together form a visible trail which reveals the flow path taken and does not contaminate objects with which it comes into contact. The addition of dosed liquid nitrogen produces a trail which remains visible at slow speeds, facilitating detailed examination of flow paths in small areas, the pattern of which would not otherwise be visible for inspection.
