Inventor: PAUL ANDREAS DIPL PHYS
IPC: G01N21/57
Filed: 1992-12-23
Abstract: For colour measurement, at least part of the surface (1) is illuminated obliquely and reflected light is received by a colour detector (3) far off the reflection angle, pref. perpendicularly to the surface, and is evaluated at least to determine the standard colour values.

Patent DE-4310136-A1 (DE)
Title: Process for cleaning stone surfaces
Inventor: SCHAMBIL FRED DR
IPC: C11D3/48
Filed: 1993-03-29
Abstract: The process is used for cleaning the surface of structural components (building components) made of concrete, stone and other mineral materials of algae, moss, fungi and similar organic contaminants. The process comprises completely wetting the surface with an aqueous dispersion of a quaternary ammonium compound, allowing this dispersion to act until the contaminants have been removed and subsequently rinsing them off using water. The quaternary ammonium compound should contain one, two or three acyloxyalkyl groups in the molecule, the acyl moiety being derived from saturated or unsaturated fatty acids having 8 to 22 C-atoms. The dispersion is free from caustic components and can be rinsed off into the waste water without problems since it is readily biodegradable. If an active substance concentration between 5 and 20% by weight in the dispersion is used, then exposure times of a few hours up to a day suffice completely to remove the organic compounds without leaving any residues.
