Appeal No. 97-2228
Application 08/509,259
The invention relates to a turbine engine rotor blade having
a vibration damper. Claim 1 is illustrative and reads as
follows:
1. A rotor blade for a rotor assembly having a disk,
comprising:
a root, for securing said blade to the disk;
an airfoil, having a base, a tip, and at least one cavity
within said airfoil;
a platform, extending laterally outward from said blade
between said root and said airfoil, said platform having an
airfoil side and a root side, and an aperture extending between
said root side of said platform and said cavity; and
a damper;
wherein said damper is received within said aperture and
said cavity; and
wherein friction between said damper and a surface within
said cavity damps vibration of said blade.
(Paper No. 11). The rather unusual step of filing the brief
prior to the notice of appeal is of no moment since the brief
itself would appear to meet the substantive requirements for a
notice of appeal (37 CFR § 1.191) and because the appropriate fee
for both a notice of appeal and a brief have been paid. The only
concern is whether the aforementioned petition/fee for a one
month extension of time (Paper No. 9) should have been for a two
month extension of time to render timely the filing of the brief
(i.e, the notice of appeal). This matter should be resolved upon
return of the application file to the examiner.
