Title: Thermal-oxidising afterburner
Inventor: NORD KLAUS JUERGEN
IPC: F01N3/24
Filed: 1984-12-04
Abstract: In order to reduce the combustion residues, such as unburnt hydrocarbons, carbon monoxide and soot, occurring in all current combustion engines, such a temperature is created in the afterburner whilst increasing the pressure by means of a retaining plate and limiting a passage that these substances can be afterburnt. Constant combustion conditions are thereby produced despite the variable engine speed and hence variable exhaust gas volumes and temperatures. At low exhaust gas temperatures an electrically operated exhaust heating is also switched on, which prevents any accumulation of solid combustion residues. A reactor part contained in the afterburner, through which a plurality of tubes passes, acts as an energy reservoir and is thus capable of imparting energy to contacting exhaust gas molecules.

Title: Circuit arrangement for voltage and current stabilisation of a high-voltage generator
Inventor: TRONICH GERT
IPC: H02M3/338
Filed: 1984-12-06
Abstract: In the case of a circuit arrangement for voltage and current stabilisation of a high-voltage generator for copiers which operate by means of a corona discharge, current stabilisation is carried out by means of a comparator stage (T2), by comparing a reference voltage (Uref) which is derived from the output voltage (UA) and a control voltage (U2) which is proportional to the difference between the total output current (IA-total) and the load current component (IA-corona) which is not effective in the copier. <IMAGE>

Abstract: The invention relates to a process for the preparation of an organic/mineral compound fertilizer and to a device for carrying out the process. It is the aim of the invention to process sewage sludge in such a way that it can be utilised as a non-hazardous compound fertilizer. This is achieved by starting from a sewage sludge which does not comprise unacceptable substances, which is introduced into the procedure in a pre-dehydrated state and which is then mixed forcibly in a manner known per se with a type of lime of a certain nature and in certain quantities, and this mixture is subsequently treated with additives which replace deficient substances or which counteract a lack of nutrients, whereupon a first heat treatment is carried out at between 300 and 600 DEG C, preferably between 350 and 500 DEG C, this temperature is then lowered to approximately 100 DEG C, depending on the composition of the mixture, in particular as a function of the water content, this lower temperature is maintained over 10 to 30 minutes, and, finally, the fertilizer product which is by now in a coarsely-granulated state, is comminuted, cooled and subjected to grading, where fines and/or granules of unduly small size are recycled into the process and the graded granules are passed to discharge devices. <IMAGE>

Title: Self-supporting sound-insulating panel
Inventor: GREINER KLAUS DIPL ING DR
IPC: G10K11/168
Filed: 1985-09-28
Abstract: For a self-supporting sound-insulating panel, a layer of rigid polyurethane foam, phenolic resin foam or melamine resin foam with very low density is proposed as effective sound-absorption medium. To protect this plastic foam layer against damage and to achieve a self-supporting sandwich structure, the plastic foam layer is laminated on both sides with dimensionally stable sheet-like structures. Cross-linked synthetic-fibre non-woven fabrics or slabstock foam layers of polyurethane foam, with a skin formed on the outside, are provided as such flat structures. This slabstock foam layer may be reinforced by a mineral fibre, glass-fibre or synthetic fibre non-woven fabric which is advantageously fused into the skin during thermal skin-formation of the slabstock foam layer. <IMAGE>
