Appeal No. 2001-1302
Application 08/811,230
terminal and the other lead is connected to the low speed
terminal. Thus, the inducer system operates at a low speed
when the furnace is vented vertically. If the furnace is
vented horizontally, one lead is connected to the common
terminal and the other lead is connected to the high speed
terminal. Thus, the inducer system operates at the higher
speed when the furnace is vented horizontally. This design
approach allows, as a further benefit, the avoidance of cost
associated with systems available from manufacturers with
two-speed/two-stage furnaces.
A copy of claims 1 through 3 on appeal can be found in the
Appendix to appellants’ brief.
The sole prior art reference of record relied upon by the
examiner in rejecting the appealed claims is:
Nelson 4,334,855 Jun. 15, 1982
Claims 1 through 3 stand rejected under 35 U.S.C. § 102(b)
as anticipated by or, in the alternative, under 35 U.S.C.
§ 103(a) as obvious over Nelson.
Rather than attempt to reiterate the examiner's commentary
with regard to the above-noted rejection and the conflicting
viewpoints advanced by the examiner and appellants regarding that
rejection, we make reference to the supplemental examiner’s
answer (Paper No. 20, mailed June 20, 2001) for the reasoning in
support of the rejection, and to appellants’ brief (Paper No. 15,
filed August 17, 2000) and reply brief (Paper No. 17, filed
January 16, 2001) for the arguments thereagainst.
