    摘要: The invention relates to the field of optical toys and amusement devices. More specifically, the invention is directed to specific immiscible liquid and semi-liquid compositions of different specific gravities and viscosities and their placement in enclosed spaces or chambers of various toy or entertainment devices thereby creating a multi phase liquid system having enhanced or dynamic visual effect. The invention employs a novel immiscible liquid mixture of hydrophobic alkane hydrocarbons and polar organic esters. In operation, as the two phase liquid system is agitated or otherwise energy stressed, the liquid of the heavier specific gravity flows through the liquid of the lighter specific gravity in distinct spaced apart beads or droplets under the influence of gravity.

    摘要: A method for making broadband cholesteric liquid crystals with improved bandwidth. The method includes the main steps of: (a) preparing a polymerization mixture containing first and second chiral liquid crystals, wherein the first chiral liquid crystal possesses a cholesteric liquid crystal phase and the second chiral liquid crystal possesses a helix-inversion characteristic, and at least one of the first or second chiral liquid crystals contains a polymerizable functional group; and (b) subjecting the polymerization mixture to a polymerization reaction, wherein the polymerization reaction is conducted such that the first chiral liquid crystal will go through a helix-inversion phenomenon. In a preferred embodiment, the second chiral liquid crystal has a temperature-dependent helicity which exhibits a helix inversion characteristic at a helix inversion temperature.
