Patent DE-3103721-A1 (DE)
Title: High-temperature gasifier
IPC: C10J3/74
Filed: 1981-02-04
Abstract: A water-cooled high-temperature gasifier for gasifying coal, wood and other fossil feedstock comprises water-cooled reactor walls with additional cylindrical tubular coils which are arranged in front of the walls and have water flowing through them and which are held against the reactor wall by cell-forming comb-shaped metal sheets. As a result of the cylindrical tubular coils with the comb-shaped sheets which completely or partially hold the slag layer which forms during gasification against the reactor wall even at very high temperature, such a gasification reactor is suitable for protecting the reactor wall against excessive temperatures. The cylindrical tubular coils can be rapidly replaced at certain intervals as a cheap part which is subject to wear.

Patent DE-3141263-A1 (DE)
Title: Process for direct printing of colour slides, and slide stages for carrying out the process
Inventor: HEINRICH GERNOT
IPC: G03C5/08
Filed: 1981-10-17
Abstract: The covering glass of the slide stage of an enlarger is replaced by phototropic material. This phototropic covering glass is irradiated, with the slide for enlarging inserted, with ultraviolet light (flash, sunlight etc.) through the slide (Figure 1). This produces a black-and-white mask of the slide in the phototropic material of the slide stage. This combination of original slide and mask acts like a low-contrast slide and can therefore be printed without problems on reversal paper by the usual processes. Since the mask in the phototropic material completely disappears again after a few minutes, this step can be repeated any number of times without fatigue. <IMAGE>
