Appeal No. 1999-0960
Application No. 08/785,437
Rejection (2)
Claim 16 reads:
16. The filter element according to Claim
1, further comprising:
an air jet housing, wherein the protective
mask has a plurality of slots which correspond
to the fold backs of the accordion fold pack,
the air jet housing adapted to detachably
sealably cover one of the plurality of slots [ ] 2
of the protective mask on the flow-off side, and
wherein a pressurized fluid may be applied to
the air jet housing from the flow-off side to
thereby clean a fold back associated with the
one of the plurality of slots, the air jet
housing being movable to sealingly cover a
different one of the plurality of slots of the
protective mask.
The additional references, Okuma and Zanma, applied in
this rejection, do not overcome the above-discussed
deficiencies of Wright with respect to parent claim 1.
Rejection (2) therefore will not be sustained.
2This recitation appears to be inconsistent with Fig. 4,
where the air jet housing 9 is shown as sealably covering a
row of slots 5 across the width of mask 3 and filter 1 (six
slots in Fig. 3), rather than just one slot.
