Patent DE-4308921-A1 (DE)
Title: Process for the treatment of biorefuse or the like
Inventor: LANGHANS GERHARD DR ING
IPC: C12P5/02
Filed: 1993-03-19
Abstract: A process for the treatment of materials or mixtures of materials which contain biodegradable substances or their precursors, in particular of biorefuse, is proposed. The materials or mixtures of materials are initially substantially decomposed enzymatically in an enzymatic hydrolysis stage (3) before they are subjected to a chemical/physical decomposition in a chemical/physical hydrolysis stage (12). The enzymatic hydrolysis stage (3) is preferably followed by a solid/liquid separation (5), with the liquid which has been separated off being fed to a bioreactor (6) for biodegradation of the organic substances, while at least part of the solids which have been separated off is returned via the chemical/physical hydrolysis stage (12) in a circulation to the enzymatic hydrolysis stage (3) or, before removal from the circulation, chemically/physically hydrolysed and washed with process water which is then again subjected to enzymatic treatment. Since the chemical/physical action takes place on the solid only after the enzymatic decomposition is substantially complete, the consumption of operating means and auxiliaries for the chemical/physical decomposition can be distinctly reduced. <IMAGE>

Title: Thermal spring for vehicle suspension
Inventor: KNAUS HANS A J
IPC: B60G17/04
Filed: 1993-12-20

Title: Coding of image source to subdivide image into fixed-height levels
Inventor: HEISLER PHILIPP DIPL ING
IPC: H04N19/61
Filed: 1994-02-23
Abstract: The image source coding operates by subdividing an image into multiple levels of fixed height.  For each image level a statistical value for the image is determined, and the levels of the image where the statistical value exceeds a pre-set threshold are coded during frames and the other levels are coded between frames.  The levels that are coded during frames are given priority over those coded between frames. The image levels are distributed between the front and rear planes, using a movement evaluation algorithm, and the image levels of the front plane have priority in coding over the images in the back plane.

Title: Recycling sewage and drain sands mixed with organic impurities
Inventor: NEESE THOMAS PROF DR
IPC: B03B5/34
Filed: 1994-10-13
Abstract: Process to recycle sewage and drain sands mixed with organic impurities. The feed (20) is passed first to a classifier (1) to separate bulky material, and the exiting fine material (2) then undergoes a multistage hydraulic cleaning.  The water-fine material-mixt. passing through the classifier passes to a hydraulic thickener (3) where it is sepd. into waste water (24) and sediment (23) contg. fine material (2). The waste water is taken away and the sediment is stored during a sedimentation phase. The sediment is whirled with water into a sand suspension (25) using a sorting cyclone (8) at a solid content suitable for the following sorting. The sand suspension is fed with a suction pump (32) to the inlet (28) of a cyclone to separate organic components, which leave at the top of the cyclone and are removed.  The pre-cleaned sand (26) leaving the bottom of the cyclone is taken to a vibrating sorter (11), which is operated such that a layer of organic material (13) forms above the sand on its vibrating belt. This layer is washed away with a water spray (12) and the sand (27) is removed.  Also claimed is a device to carry out the above process.
