Application No. 08/932,090
matter of the appellant's claim 1, and for this reason we do
not sustain the examiner's rejection of appealed claim 1, or
of claims 2 and 4 through 15 which depend from claim 1, under
35 U.S.C. § 103 as being unpatentable over Oldham taken
together with Ruemelin.
--The 35 U.S.C. § 103 rejection over Gueyrard and Ruemelin--
We shall sustain this rejection.
Gueyrard discloses an apparatus for receiving poured
product which may be granular, pulverized, or dust, and
including an automatic dust separator (page 1). Gueyrard
discloses (Fig. 1) a charging opening in a housing with a
safety grid (3), a suction fan (7), filters (6), a suction
chamber (4) and a cone (hopper) (8) for receiving the product
(page 4). It is our view that the larger material poured on
Gueyrard 's safety grid (3) falls into the cone while air
flows (Fig. 1) from outside the housing through the safety
grid (3) then through the filters (6) and out through the
suction fan (7) leaving particles trapped in the filters (6).
