Appeal No. 95-0647
Application No. 08/026,246
DECISION ON APPEAL
This is an appeal from the final rejection of claims 1,
2, 5, 8 through 11 and 13. In an Amendment After Final (paper
number 20), claims 1 and 8 were amended. As indicated in the
Advisory Action (paper number 21), the amendment had the
effect of overcoming the rejection under the first paragraph
of 35 U.S.C. § 112.2
The disclosed invention relates to a monochrome cathode
ray tube (CRT) for a projection television.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. A monochrome cathode ray tube for projection
television comprising in an evacuated envelope a display
screen on a convexly curved inner surface of a display window
in the wall of the envelope, the display screen comprising a
layer of a luminescent material, characterized in that means
for attenuating at least the wavelengths of radiation
corresponding to the luminescent output of the tube area
uniformly distributed in the display window so as to attenuate
all wave lengths of said radiation by about the same amount,
said amount being such as to result in a transmission of the
display window in the range of about 70 to 90 percent thereby
2We assume that the rejection under the second paragraph
of 35 U.S.C. § 112 was likewise overcome by the amendment
because the indefiniteness rejection was not repeated in the
Answer.
