Appeal 2007-1243
Application 10/336,018
8. Appellant’s admitted prior art does not disclose the fluid flowing to
counteract the out of balance condition of the color while the color wheel is
rotating. Further, one skilled in the art would readily recognize that the methods of
drilling holes or adding adhesive can not be accomplished while the color wheel is
rotating.
9. From both Hung and Appellant’s admitted prior art, one skilled in the art
would recognize that the efforts to balance the disk involve relatively permanent
adjustments to the disk. Similarly, one would recognize that the eccentricity of the
disk which causes the imbalance is also relatively permanent so that when the
adjustments are made the disk is balanced.
10. Goodrich teaches an automatic balancer for rotating masses. Goodrich
Abstract.
11. The balancer comprises a casing containing metal balls in an annular race.
Goodrich col. 1, ll. 53-58.
12. In operation the balancer is concentrically mounted to a rotating object,
during rotation the balls position themselves to oppose the eccentric mass, thus
reducing vibration. Goodrich col. 2, ll. 25-29.
13. The casing is filled with lubricant which dampens the movement of balls.
Goodrich, col. 2, ll. 6-8.
14. Goodrich identifies that one of the problems with prior art devices is that
they were not precision made and at high speeds the balls tended to bunch up
creating worse vibrations. Goodrich, col. 1, ll. 8-15.
15. From this disclosure we find that one skilled in the art would recognize that
the precision manufacturing is the solution to the ball bunching problem and the
lubricant is to provide dampening.
