  • Patent number: 10662150
    Abstract: A sulfonic acid salt composition includes compounds of formula (I), wherein n is 1 or 2, R1 is H or C1-C6 alkyl, R2 is COOM, SO3M or CH(OH)SO2—OM, each M is an equivalent of a multivalent metal, preferably magnesium, calcium, aluminum, zinc and combinations thereof. The molar ratio of a compound wherein n is 1 to a compound wherein n is 2 is below 0.1. The sulfonic acid salt composition is useful for color stabilization of non-living organic matter such as from lacquers, paints, powder-coatings, and polymers in particular water-absorbent polymers.

  • Patent number: 10488650
    Abstract: A micromechanical component includes an adjustable part, a mounting, at least one bending actuator, and a permanent magnet. The part is positioned on the mounting so as to be adjustable relative to the mounting about a first rotation axis and about a second rotation axis inclined relative to the first axis. The actuator includes at least one movable subregion. Movement of the subregion results in a restoring force that moves the part about the first axis. The part is connected indirectly to the magnet to be adjustable about the second axis of rotation via a magnetic field built up by the magnet together with a yoke device of the component or an external yoke. A micromirror device includes the micromechanical component. A method for adjusting the part includes adjusting the part simultaneously about the first and the second axes.
