Appeal No. 2000-0181
Application No. 08/929,287
The appealed claims are drawn to a rotating nozzle for
spraying jets of fluid, and are reproduced in the substitute
appendix filed on February 23, 2000.
Claims 1, 4 to 17 and 20 to 26 stand finally rejected for
failure to comply with 35 U.S.C. § 112, first paragraph, in
that the claimed invention is not described in the
specification in such a manner as to enable one of ordinary
skill to make and use it.
After fully considering the record in light of the
arguments presented in appellants’ brief and reply brief, and
in the examiner’s answer, we conclude that the rejection is
not well taken.
The rotating head 22 of appellants’ nozzle is driven by a
turbine 13 rotated by the operating fluid, e.g., water. As
disclosed at page 2, lines 19 to 31, and page 8, line 30, to
page 9, line 22, the nozzle of the invention is so constructed
that, as the pressure of the operating fluid increases, the
rotational speed of the nozzle head will increase
proportionally. However, after the fluid pressure reaches a
certain value, such as 0.5 bar, further increases in pressure
