steering reaction control arrangement and which also focuses
on solving the same problem. The reference discloses a system
wherein a right annular collar (17) is attached to the end of
the control sleeve (16) by means of a pin (19) and slot (20)
connection, and this collar fits inside a right annular recess
(18) on the adjacent end of the carrier sleeve (10a). The
control sleeve and the collar therefore can be rotated
together with respect to the recess in the carrier sleeve.
When proper alignment is achieved, the collar “is locked to
the carrier sleeve 10a by any convenient means such as
welding, bonding, peening or pinning so that the sleeve 16 and
carrier 10 will then rotate in unison” (page 9, lines 21-24).
UK ‘000 clearly does not disclose or teach the claimed
inner and outer cone structures which permit relative rotation
until alignment is achieved and then can be pressed together
to lock the components in place. Even though this was pointed
out by the appellants in the remarks accompanying the first
amendment (Paper No. 6) and in the Brief, the examiner has not
explained why this feature would have been obvious in view of
UK ‘000, and we are unable to determine this on our own. It
