  • Patent number: 11130882
    Abstract: The present disclosure is directed to a solvent borne non-isocyanate curable two-components coating composition, comprising: component a) a film-forming resin composition comprising a resin component having carboxyl functional groups and hydroxyl functional groups and having an acid value of at least 23 mg KOH/g resin; and component b) an aromatic polycarbodiimide having two or more —N?C?N— moieties, wherein the carboxyl functional groups of the resin component and the —N?C?N— moieties present in the aromatic polycarbodiimide have a molar ratio in the range of 1:2 to 2:1, preferably in the range of 1:1 to 2:1; and wherein the coating composition comprises less than 1 wt % of water relative to the total weight of the coating composition. The present disclosure is also directed to an article comprising a substrate and a coating disposed thereon formed by the above solvent borne non-isocyanate curable two-components coating composition.

  • Publication number: 20050060256
    Abstract: A method for providing an interface for Foreign Exchange trading centered on an FX rate tile. The tile interface offers harmonized order and RFQ submission workflows. Users can also configure order and quote parameters by using input features of the tile display. The tile also serves as a flexible unit of display and order/quote creation. The tile can be resize, rearranged, torn off and joined into new windows. The above described features contribute to provide a unique harmonized, flexible, “tiled” foreign exchange trading interface.

  • Publication number: 20040225388
    Abstract: The invention relates to a fully digitized audio system comprising a power supply and a decode and sound field effect process unit, characterized in that a digital audio signal output from the decode and sound field effect process unit is transmitted to a control and encode unit where audio and control signals are encoded, and coupled to a digital sound box through a digital transmission terminal in the control and encode unit. The invention adopts totally digitized audio signal processing according to the concept of mechatronics, solving the problem of distortions rising throughout the procedure from input, process, distribution, transmission and amplification to sounding, to ensure a controllable hi-fi output of audio signal. The audio system according to the present invention provides high fidelity, good controllability, and easiness of assembling, and is suitable for mass production of advance audio systems.
