Patent DE-4001895-A1 (DE)
Inventor: KLEMKE RUDOLF ERICH DIPL CHEM
IPC: C07J17/00
Filed: 1990-01-23
Abstract: Novel glycosides, especially steroidal glycosides, and a novel method of their production, are provided. For the novel method of producing novel glycosides, hydroxysteryl compounds are glycosylated with tri-O-acyl glucal using molecular iodine as a reaction catalyst. In this method an alcohol or phenol, especially a hydroxy-steroid such as a water-insoluble cholesterol, is glycosylated, such that the glycosylation is performed in a single step. The resulting steryl pyranoside is by oxidation converted to the corresponding 7-ketosteryl di-O-acyl-pyranoside. The latter pyranoside is selectively reduced to provide the corresponding 7-(beta)-hydroxysteryl 2,3-dideoxy-(alpha)-D-erythro-hex-2-enopyranoside. The steroidal glycosides obtained in this way possess valuable pharmacological properties. In particular, the glycosides in vivo exhibit a selective cell-destructive activity on malignant cells which activity is substantially free of side effects on normal cells. The glycosides also possess a drive-enhancing (stimulating) activity and an anti-inflammatory (immunosuppressive or immunoregulatory) activity.

Patent DE-4006184-A1 (DE)
Title: Measuring width and spacing of bar codes - using single photosensor whose speed is derived from signal for absolute measurement independent of speed of movement
Inventor: HERZOG HOLGER
IPC: G06K7/016
Filed: 1990-02-28
Abstract: A method of measuring bar codes involves moving a photosensor along the bar code to be measured, computing the speed from the sensor signal and determining the separations and widths of the bars from the speed and the time variation of the sensor signal. Only one photosensor with a defined aperture width and shape is used. The speed is derived in a computer from the signal (s) time characteristic as the sensor passes over a bar edge (2a, 2b) and from the aperture width (B). USE/ADVANTAGE - Esp. for use on goods priced and identified with bar codes. Absolute measurement of bar separations and widths is achieved irrespective of speed and at relatively low cost, i.e. without using additional photosensor for reference.  Ascertains if codes printed on labels, packets etc. lie within tolerance limits.
