Appeal No. 1998-2064
Application 08/710,551
for (1) a female thread supported by the upper member of the
main body such that it is moveable in the axial direction
relative to the upper member of the main body, and (2) a first
impact absorbing means interposed between the female thread
and the lower member of the main body. Becker discloses at
column 6, lines 8-13, that roller nut 74 is fixedly mounted to
housing member 8. Becker is silent as to the provision of an
impact absorbing means between the
roller nut 74 and either the upper housing member 8 or the
lower housing member 10. Thus, it is clear that Becker lacks
a female thread “supported in the upper member . . . [and]
being moveable in an axial direction” as called for in claim
5, and “first impact absorbing means interposed between a
lower surface of the female thread and an upper surface of the
lower member” as also called for in claim 5.
Markus pertains to an electromotive servo drive for use
as an actuator for a valve or the like in a pipe system
