Patent DE-4028306-A1 (DE)
Inventor: BACHELIER HEINZ-JUERGEN
IPC: B01F15/00
Filed: 1990-09-06
Abstract: The invention concerns a stirrer assembly, designed to fit into a container, with at least one stirrer shaft which can be raised and lowered in the axial direction plus a drive unit, with at least one drive shaft, mounted by means of a supporting housing on the container. The drive shaft and stirrer shaft are detachably connected to each other outside the container by means of an intermediate element with a seal allowing the stirrer shaft to pass through the wall of the container. The seal (11) is disposed a certain longitudinal distance from the opening (9) for the stirrer shaft (5) and rests against a seal housing (18) which covers the connection between the intermediate element (1) and the stirrer shaft (5) and which is designed to be tightly joined to the seal (11) and the container wall (10). In addition, the seal housing (18) and the seal (11) can be telescoped together in the axial direction. A stirrer assembly of this kind is compact and simple in design, and enables the stirrer-shaft seal in the container-wall opening to be changed rapidly with either normally or coaxially mounted stirrer shafts.

IPC: F26B21/04
Filed: 1991-01-16
Abstract: Process and appts. for drying prods., partic. foodstuffs to retain the aroma, and other valuable materials. The drying gas, usually air, flows around a closed system and passes one side of a membrane where the moisture is extracted by heat exchange  leaving the aroma and other valuable materials in the drying gas.  On the remote side of the membrane a flushing gas removes the sepd. moisture. The membrane comprises a pore-free active layer laminated with a thicker porous carrier. Both layers are mfd. in plastic with diffusion coeffts. harmonising with those of the material to be sepd.. The prod. is located in a dryer (1) through which drying air flows and picks up moisture from the prod.. The air then flows to an opposing stream heat exchanger (2) where it is pre-heated to a given temp.. A subsequent heater (3) heats the air to a final temp. before it flows to a material exchanger (4) where it passes a membrane (5). Selective extn. of moisture occurs, leaving the aroma and other useful materials in the recirculating air stream. USE/ADVANTAGE - The process is used for selective drying of prods., partic. foodstuffs contg. a mixt. of moisture types, and retains higher levels of aroma and other valuable materials.

Title: Vacuum furnace for heat treatment of metal parts - has cover walls inside heating chamber to confine carriage area to minimal size thereby increasing cooling effects of blown gas
Inventor: KRISTEN SIEGFRIED
IPC: C21D1/767

The covers may be flat with a 10 mm thick wall and the cooling gas is blown from the top and bottom of the heating chamber. ADVANTAGE - The reduced charge area enables the cooling gas to be concentrated on the hot parts and thereby increase the cooling effect.
Patent DE-4117323-A1 (DE)
Inventor: WUEST WILLI DR
IPC: C09D7/43
Filed: 1991-05-27
Abstract: The invention concerns a simplified process for the production of fluoride-containing, swellable magnesium layer silicates of the smectite type, in particular compounds of this type with the hectorite structure, the process including a hydrothermal reaction step between the layer-silicate-forming reactants at elevated pressures and temperatures. The new process is characterized in that a hydroxidic coprecipitate of magnesium and silicon, optionally virtually free of foreign salts, in alkaline aqueous suspension, and in the presence of dissolved MgSiF6 and/or other salts supplying fluoride ions, is subjected to a hydrothermal reaction and the solid formed is optionally separated, after cooling, from the aqueous phase and from any foreign salts dissolved in it. The moist product thus obtained does not swell significantly in water. The invention calls, as the last process step, for this moist product to be dried at moderately temperatures, thus forming in this step the crystalline, high-swelling layer silicate. The invention also concerns the use of layer silicates produced in this way in the thickening of liquid aqueous phases. When layer silicates produced by the process proposed are provided, using prior art methods, with oleophilic groups, these modified thickening agents are suitable for use in organic phases.
