  • Patent number: 8372307
    Abstract: The invention relates to new cyclohexylene reactive mesogens (RM), polymers derived thereof, liquid crystal (LC) media comprising them, and the use of the compounds, polymers and liquid crystalline media in optical, electrooptical, electronic, semiconducting or luminescent components or devices, in decorative, security, cosmetic or diagnostic applications, especially in the polymer stabilised blue phase.
    Type: Grant
    Filed: October 26, 2007
    Date of Patent: February 12, 2013
    Assignee: Merck Patent GmbH
    Inventors: Louise Diane Farrand, Kevin Adlem, Andreas Taugerbeck, John Patrick, Christopher John Dunn, Janice McCreary
  • Patent number: 8212646
    Abstract: The present invention relates to a fuse assembly for rapid interruption of a prospective fault current. The fuse assembly includes a plurality of splitter plates. A plurality of foil elements extend between a pair of terminals and are physically supported by the splitter plates. A pair of parallel busbars are in series with the foil elements and generate a magnetic field that is substantially perpendicular to the current flowing in the foil elements. In the presence of a prospective fault current, the foil elements will melt and at arcing inception an electromagnetic force developed as a result of interaction between the magnetic field and the arc current will push the molten foil elements into the splitter plates. This increases the arc length and hence the arc voltage. At least the foil elements and the splitter plates are preferably located in flowing liquid dielectric such as MIDEL 7131, for example.
