and definiteness required by § 112, second paragraph.
The body of claim 9 is drafted in such a way that it
appears to be directed to the combination of a static seal, a
dynamic seal, a barrier liquid supply, at least one swivel
member and a ring element. For example, claim 9 calls for “a
barrier
liquid supply communicating with said static and dynamic
seals.” As explained above, the underlying specification
identifies the barrier liquid supply as the channels 20 and 50
and the means by which the barrier liquid supply communicates
with the static and dynamic seals as various openings or
passages formed in one of the swivel members 2 or 3, including
grooves 16 and 48, and passages formed in the ring elements 17
and 47. Thus, according to the underlying specification, in
order to have a barrier liquid supply communicating with
static and dynamic seals, there must be certain structure,
i.e., a swivel member provided with a supply channel and
passages, including a groove, interconnecting the supply
channel with the static and dynamic seals and a ring element
