Title: Heat recovered from condensing gaseous tetra:chloro-ethylene used to dry cleaned metal components
Inventor: GOETZE HORST
IPC: B08B3/08
Filed: 1992-12-23
Abstract: Batch charges of metal components are cleaned by means of tetrachloroethylene solvent within a closed chamber. After the cleaning process the solvent is discharged from the closed chamber and the residual gaseous tetrachloroethylene is drawn off and recovered by condensation. The cleaned metal components are dried by air. The novelty is that the heat recovered from the condensing gaseous tetrachloroethylene is used to heat air which then dries the cleaned metal components; further that any remaining gaseous tetrachloroethylene is passed to a second discharge treatment stage where it is passed through an absorbent which is regenerated from time to time by heating to a temp. above the b.pt. of tetrachloroethylene.The drying process receives an additional input of heat energy. The adsorbent is active carbon. The active carbon adsorbent is regenerated by steam arising from solvent distillation.

Patent DE-4431117-A1 (DE)
Inventor: REIME GERD
IPC: H04B10/06
Filed: 1994-09-01
Abstract: A circuit is used to set the operating point of at least one opto-electronic component, e.g. a photodiode (10'), in which the opto-electronic component is part of a receiver for useful alternating light signals. In order to set the operating point below the saturation voltage of the opto-electronic component, a resistance circuit is connected in parallel with the opto-electronic component at least to compensate for direct light signals. The resistance circuit has a self-adjusting resistor, the resistance variation of which is at least voltage-dependent as soon as a given voltage below the saturation voltage is exceeded and thus loads the opto-electronic component until the set voltage is substantially attained. The compensation current required owing to the direct light is produced without an outside voltage in such a way that virtually no current need be taken from the power supply.
