摘要:
Disclosed is the use of an aqueous dispersion comprising (a) a micronized sparingly soluble organic benzophenone derivative of formula (1), selected from the crystal modifications (B) and (C), wherein the crystal modification (B) is characterized by a peak in the X-ray diffraction pattern at a d-spacing of about 7.70; and wherein the crystal modification (C) is characterized by a peak in the X-ray diffraction pattern at a d-spacing of about 7.06; and (b) a dispersing agent selected from anionic, non-ionic and amphoteric surfactants; for protecting the human skin from browning and skin aging. The new crystal modification (C) represents a thermodynamically stable compound of formula (1) at 25° C. This modification is therefore suitable in dispersions comprising micro-fine particles.
摘要:
Disclosed is a wind-powered watercraft in which a free-flying kite-type wind-attacked element that is provided with a profiled wing and is used as the exclusive, an auxiliary, or an emergency drive unit is connected to the vessel only via one traction rope, said traction rope optionally fanning out into a number of holding ropes. The wind-attacked element can be modified via at least one active drive element that is disposed thereupon and is effectively connected thereto by modifying the aerodynamic effect thereof in order to be guided into a given position relative to the watercraft or to dynamically maneuver.

摘要:
Process is for environmentally friendly, low-waste reprocessing of side dams for the continuous casting of thin steel strip having a mechanically or chemically worn surface. The mechanically or chemically worn surface of the side dams is cleaned by methods known per se and the side dams are subsequently converted into a BN-containing powder by crushing and milling.
