Patent DE-4127297-A1 (DE)
Inventor: KAHLE HANS JOACHIM DR
IPC: B09C1/00
Filed: 1991-08-17
Abstract: The invention relates to a process, by means of which waste material in landfills, preferably from old dumps in domestic refuse landfill sites which are no longer active, or from old dump areas of sites still operating, can be reprocessed in order to reduce the original extent of the landfill site at a later stage and hence to recover useful areas. After coarse materials have been sorted out, the material taken from the landfill is subjected to float fractionation in water basins, in which biodecomposition with production of a biomass also takes place. Combustible floating materials, excess biomass, combustible coarse materials and biogas obtained from biomass are burned to release useful energy. Ash and incombustible material, which is comminuted if necessary, require substantially smaller landfill areas for dumping.

Patent DE-4130931-A1 (DE)
Inventor: HOEFT ANDREAS DR MED
IPC: A61B5/0275
Filed: 1991-09-13
Abstract: The description relates to a process and device for determining the volume of blood in circulation by the injection of a predetermined quantity of indicator colorant into the bloodstream. The blood volume is calculated via the fibre-optical measurement of the colorant concentration in a central vessel, e.g. from the predetermined quantity of the indicator colorant injected and the cycle of the colorant concentration. Here, the colorant concentration is measured immediately after the predetermined quantity has been injected into the bloodstream and a circulatory transport function g(t) is calculated from the measurement of the colorant concentration. Via the circulatory transport function g(t) is determined the circulatory pulse response d(t) which would correspond to an ideal indicator injection in an extremely short time at a time t=0, the virtual colorant concentration c0 at time t=0 is determined from the circulatory pulse response d(t) by back-extrapolation or direct calculation from the parameters of the circulatory transport function g(t), and the blood volume Vd-blood is calculated from the predetermined quantity m0 of indicator colorant injected and the virtual colorant concentration c0 at time t=0 by the relation Vd-blood=m0/c0.

Title: Decontamination of earth soiled with toxic matter, etc. - by sepg. dry soil into heavily contaminated and usable fractions without using water
Inventor: MUCKENHIRN FRANZ K
IPC: B03B9/06
Filed: 1992-05-27
Abstract: Decompsn. comprises initially sorting while dry into one fraction which is heavily contaminated and requires processing and a further fraction of a tolerable contamination level. Also claimed is a sorting assembly with a coarse double decker sieve (2) with a mesh width of 60 mm. and 40 mm., within a rotating vessel (9). A shorting unit (11), after the rotating container (9) has a multi-stage sieve assembly to separate the material to be processed from the harmless matter. In the initial coarse sorting stage (2), matter with a large particle size such as 40 mm. and more, is sorted out for shredding (3). The remaining material of less than 40 mm., passes by a magnet strip (6) to separate metals. The material to be processed is fed to a rotating container (9) which gives a mechanical sorting action into coarse and fine matter and also dries it. The sepd. coarse and fine components are passed to a sorter (11) with a number of rotor units (12) which apply a mechanical action in the flow direction and fine matter (13) is removed. A further multi-stage sieve assembly pref. with two stages, each with two sieves of the same characteristics, separates the material which is soiled too heavily according to its dia. The material, between two converging sieves of the same characteristics is further processed by a rotator and a separator for the light material. Further sorting separates specifically unsoiled material and the finest adhering particles are sepd. for disposal. USE/ADVANTAGE - The system is for cleaning and decontaminating ground areas which have been soiled and contain toxic materials, as preparation for construction and esp. dwellings. The soil can be contaminated by inorganic mercury, lead and cadmium or organic matter such as chlorhydrocarbons, aromatics and dioxine. The method requires little water consumption without wet sorting even for the finest materials.
