20110274469 | HIGH CONDUCTIVE, SOFT URETHANE ROLLERS - Rollers for high speed printers and paper handling devices are fabricated by reacting polymeric diphenylmethane diisocyanate with a polyester polyol and/or polyester polyamine and an optional extender, together with a metal salt, a catalyst, and one or more other optional additives, including a liquid conductive additive. The resulting rollers provide a hardness as low as 15A on cube, a resistivity as low as 5E4 Ω·cm, a compression set as low as 0.5% at room temperature and as low as 3% at 157° F., and low tackiness as low as 13 g/cm of adhesion force. | 11-10-2011 |
20080246330 | In-line Skates, Skate Wheels and Wheel Hubs - A skate wheel for an in-line skate includes a skate wheel hub having an inner hub, an outer rim, and, extending therebetween, a plurality of blade-form spokes. A skate tire is mounted upon an outer surface of the outer rim of the skate wheel hub. Opposed surfaces of adjacent blade-form spokes, in cooperation with opposed surfaces of the inner hub and the outer rim, define airflow passageways through the skate wheel. Each blade-form spoke includes a radially-aligned first spoke-edge surface exposed at a skate wheel face, a radially aligned opposite, second spoke-edge surface exposed in a region of a center plane defined by the skate wheel, and a body extending smoothly between the first and second spoke-edge surfaces. Also described are in-line skates with skate wheels of the disclosure, and skate wheel hubs for such skates. | 10-09-2008 |
