Patent DE-4132304-A1 (DE)
Inventor: BRAUNSTEIN ULRICH
IPC: G06V30/10
Filed: 1991-09-27
Abstract: Once a black pixel has been detected in a binary coded pattern (PI), the environment of the black pixel having a reduced number of neighbouring pixels is checked for further black pixels. The thus determined real size of the continuity zone (for example CC1) formed by all detected black pixels is compared to a predeterminable maximal size. If the real size is smaller than the maximum size, an increased number of neighbouring pixels, with respect to the previously selected number, is selected, and the environment of each pixel belonging to the already built continuity zone (for example CC1) is checked for additional black pixels on the basis of said increased number of neighbouring pixels.

Patent DE-4222153-A1 (DE)
Inventor: PETER SIEGFRIED PROF DR
IPC: C11B7/00
Filed: 1992-07-06
Abstract: A process is disclosed for recovering the lecithin contained in oil and lecithin mixtures by extraction with an extracting agent containing at least one hydrocarbon. The extraction with one or several C3- or C4-hydrocarbons is carried out in such conditions that the extracting agent forms with the lecithin a low viscosity solution and the extraction mixture decomposes into an oil-rich liquid phase and a lecithin-rich liquid phase. Both phases are separated and substantially lecithin-free oil is recovered by separating the extracting agent from the oil-rich phase and substantially oil-free pure lecithin is recovered by separating the extracting agent from the lecithin-rich phase.
