denied, 488 U.S. 825 (1988).
The appellants’ invention is directed to a steering
reaction force control arrangement for a hydraulic servo valve
of a power steering system. During the assembly of such
devices, it is necessary to provide a mechanism for allowing
rotational adjustment of a control sleeve and an adjacent
sleeve structure with respect to one another so they are in
proper relationship prior to fixedly attaching them together.
In furtherance of this, independent claim 1 requires, inter
alia, a control sleeve and a sleeve structure, each
having cooperating conically shaped adjacent end
portions, one being provided with an outer cone
structure and the other with an inner cone structure
by which they are engaged with one another in an
angular position . . . .
In operation, the inner and outer cone structures are loosely
placed together so that at least one can be rotated until it
is in the proper relationship with the other, whereafter they
are pressed together to establish a tight fit that precludes
relative rotation.
The examiner has rejected this claim as being
unpatentable over UK ‘000, which also is directed to a
