Appeal No. 95-4860
Application No. 08/044,923
disclosures of O’Connor and Streich and claims 20-22 based on
the combined disclosures of O’Connor, Streich and Leroy.
Under the provisions of 37 CFR § 1.196(b) we make the
following new rejections.
Claims 18-22 are rejected under 35 U.S.C. § 112, first
paragraph, as being based upon a nonenabling disclosure since
the appellant’s disclosure provides no teaching of how to
“make and use” an embodiment wherein the second pressure plate
is threadably coupled to the third end of the second shaft as
claim 18 sets forth. Viewing Fig. 2 of the appellant’s
disclosed embodiment, a resilient sealing material 61 is
positioned between a fixed or first pressure plate 40 and a
second or movable pressure plate 41 and movement of the
movable or second pressure plate towards the fixed or first
pressure plate causes the resilient material to expand against
the inner surface 72 of the pipeline. If, as this claim sets
forth, the second or movable pressure plate was threadably
coupled to the second shaft, then no movement of the second
pressure plate toward the first pressure plate could occur
unless somehow (1) the second shaft 12 was reciprocated
