A reel assembly comprising a pivotable guide arrangement for guiding material to and from a drum portion of the reel assembly, the guide arrangement being resiliently biased towards an undeflected position. Additional data values represented by corresponding groups of segments are written into the data structure. By manipulating various operating factors\u2014position of substrate in the reactor, amount of water vapor, amount of catalyst, reactor temperature, and growth time, the morphology and thickness of these carbon nanotube films could be adjusted. The front section formed from a single sheet metal plate. A user of the invention need not keep trying a busy number, and the feature can be paid for by revenue from selling the advertising. The gaming device then provides any award associated with the determined combination to the player.
