Appeal No. 1998-1639
Application No. 08/424,259
a combined power absorbing and inertia simulating
unit having a ferrous rotor wheel rotatably mounted on
the frame for rotation with the roll and a stationary
field coil arrangement positioned adjacent the rotor wheel
for inducing eddy currents in the rotor wheel to apply said
braking force to the wheel, the rotor wheel being in the
form of a drum open at one end with a hollow braking
section extending axially from the open end to a web section
extending radially inwardly to a hub mounted on the
shaft, the rotor wheel having a rotational inertia which is
within the range of 50 to 90% of the base inertia of the
dynamometer.
The reference relied on by the examiner is:
La Belle 5,385,042 Jan. 31, 1995
(filed Aug. 21, 1992)
Claims 13, 19, 22 through 24, 32 and 33 stand rejected
under 35 U.S.C. § 103(a) as being unpatentable over La Belle.
Reference is made to the brief and the answer for the
respective positions of the appellants and the examiner.
OPINION
The obviousness rejection of claims 13, 19, 22 through
24, 32 and 33 is reversed.
The examiner acknowledges (Answer, page 4) that La Belle
“fails to explicitly teach the rotor wheel being in the form
of a ‘drum’ open at one end with a hollow braking section
extending axially from the open end to a web section extending
radially inwardly to a hub mounted on the shaft.” According
