Combinations of at least two individual colorant compounds that provide effective toning to combat yellowing within polyester articles are provided. According to the present invention, two or more ECC blocks are written between a run-in field and a run-out field. Information related to the multi-word names is also stored as a gloss to the terminal node of the multi-word entry of the trie-based dictionary. After contraction, the now-porous membrane can be used to form the outer wall of the balloon assembly. An opposite end of the suspension arm is connected to the vehicle by a shock absorbing member and rotatably supports the wheel and driven pulley to thereby allow upward and downward movement of the wheel and driven pulley while maintaining the belt in positive engagement with the drive and driven pulleys. Adjustments may include adjusting a moving mass of one of the elector-acoustic transducers.
