Patent DE-4135313-A1 (DE)
Inventor: EDENHOFER BERND DR
IPC: C21D11/00
Filed: 1991-10-25
Abstract: In a method for cooling a charge of workpieces during a heat treatment process by means of gas cooling, the parameters governing the cooling process, for example cooling gas velocity and cooling gas pressure, are set as a function of temperatures determined during the cooling process. The cooling of the charge of workpieces is to be controlled in such a way that the desired heat treatment result is obtained on a predetermined workpiece cross-section, without temperature measurements being required at this or another point of the workpiece. For this purpose, the temperatures (T1, T2, T3, T0) are detected by means of at least one measuring probe, arranged in the charge chamber, of defined geometry and defined material. By means of a computer, the temperature/time curve in the workpiece is calculated on the basis of these temperatures (T1, T2, T3, T0) via the determination of the heat flux density and the heat transfer at the measuring probe. By means of a comparator device, the computer carries out a continuous comparison between the actual temperature curve (Tw,actual) calculated in this way and a preset desired temperature curve (Tw,desired). The parameters governing the cooling process are then controlled as a function of the result of this comparison. <IMAGE>

Title: Sewage solids removal - involves applying eddy action to wash solids for extraction to leave liq. and organic matter
Inventor: BISCHOF RUDOLF
IPC: B03B5/52
Filed: 1992-07-06
Abstract: To prepare solids in sewage, sand, rubbish and the like, the solids in the fluid are sepd. from organic matter by a fixed and structured eddy action to wash them out, while the organic matter passes out with the fluid. The recovered solids are dumped, incinerated or given a low-moisture heat treatment. Pref. the eddy and washing action on the solids is applied to the soiled water before they are removed, such as in a gulley, or in a container after they have been lifted from the soiled water. The solids, including those provided by external sources such as rubbish, are mixed with a washing fluid before the eddy action, such as pretreated sewage or waste water. The mixt. of liq. and solids can be eddied repeatedly. The eddy action is applied intermittently as charges are fed to the eddy zone. The eddy action can be applied to a mixt. of gas/fluid or to a gas, using a rapid-rotation motor-driven eddy wheel. ADVANTAGE - The technique gives an improved sepn. of solids from sewage and other liq. waste matter, for safe and simple disposal.
