Abstract: An endless fabric belt subjected to a substantial running tension. The belt has an endless woven fabric formed from a plurality of MD (machine direction) ultra high molecular weight polymer strands approaching zero creep at high tensile loads. A plurality of CMD (cross machine direction) strands are interwoven with the MD strands. The plurality of MD strands have first and second ends spliced to one another to form an endless belt, the splices forming a significant linear MD overlap of about 30 cm with each other.

Abstract: Robustaflavone, intermediates and analogues thereof and a method for synthesizing the same are provided. The method involves constructing apigenin ethers containing functionalities at the 6- and 3′-positions which could be cross-coupled using transition metal catalysis. The method also involves development of a regioselective iodination of an apigenin derivative at the 6-position, formation of an apigenin 3′-boronate using a palladium-catalyzed exchange of the corresponding 3′-iodide with a diboron reagent. Finally, Suzuki coupling to form the sterically congested 6-3′″ biaryl bond of robustaflavone provides access to the desired biflavanoid system. Robustaflavone intermediates and analogues may be used to prepare analogues of other biflavanoids such as hinokifavone, rhusflavone and succedaneaflavone.
