Patent DE-4202821-A1 (DE)
Inventor: ROCKSTEDT SIEGWARD
IPC: B29C48/67
Filed: 1992-01-31
Abstract: Multi-screw, continuous mixing and kneading machine for plasticizable compounds with screws, which rotate in a housing and which penetrate the cylindrical housing section, enclosing the screw concerned, and exhibit feed and discharge zones and intermediate melting, mixing and kneading zones, where the feed and discharge zones are formed by intermeshing screws that rotate in the same direction, and kneading elements are disposed in the melting, mixing and kneading zones. The kneading elements comprise axially extended polygons, whose surfaces are approximately flat and whose edges travel by one another with small clearance relative to the envelopes of the respective other polygon so as not to intermesh while rotating, where the edges of the housing section enveloping them maintain a distance that is significantly greater than the clearance.

It has lower viscosity than gel formers based on Al phosphate and free from B, so that the cavity between panes of glass can be filled very quickly and without bubbles. In an example, a 55% soln. of 1 mole AlH2PO4 (obtd. by reacting 1 mole Al(OH)3 with 3 mole 85% H3PO4 in water at 100 deg.C) was stirred with 3.1 mole ethanolamine, starting at 20 deg.C, when the temp. rose to 75 deg.C. The soln. was clear after a few mins. and was cooled to 20 deg.C. It contained 66% solids. After 16 hrs. at 20 deg.C, the viscosity was 3800 mPa.s. 9 Pts. of this soln. were mixed with 1 pt. 66% aq. soln. of the reaction prod. of 1 mole H3BO3 and 1 mole monoethanolamine at room temp., giving a clear soln.. After 16 hrs. at 20 deg.C, this had a viscosity of 630 mPa.s. The mixt. was heated to 80 deg.C in a glass flask, when it gelled in 4 hrs.. Heating was stopped after 12 hrs., giving a clear stable gel. If this was heated 180 hrs. at 80 deg.C, then cooled, the gel did not become turbid.

Patent DE-4301322-A1 (DE)
Inventor: FEUSTEL HANS ULRICH
IPC: C21B11/02
Filed: 1993-01-20
Abstract: The invention relates to a process which is characterised by low melting costs and also reduces the environmental load and to a simple-functioning piece of equipment for melting iron alloys, in particular steel scrap, in a coke-fired cupola furnace for the production of cast iron. According to the process, the furnace gas is partially withdrawn at a temperature of > 400 degrees Celsius in the preheating zone and is simultaneously fed in again in the melting and superheating zone with > 23 per cent oxygen. A further characteristic is that the partially withdrawn furnace-gas quantity constitutes up to 70 per cent of the furnace gases resulting in the melting process. Through feeding in furnace gas, in particular through the CO content of the furnace gas, gaseous fuel is fed in which burns with the oxygen. The reducing conditions in the gas-fired cupola furnace are thus intensified, in turn resulting in an improvement of the metallurgical effects. <IMAGE>
