reradiator components 48 and 50 (column 3, lines 43-50). The
principle function of the reradiator
is to provide a large surface at a uniform high
temperature, resulting in the conversion of a large
percentage of the heat of combustion to radiant
energy, primarily in the 1-12µ range of wave
lengths. In operation, the entire surface of the
reradiator is heated to incandescence and may reach
a temperature several hundreds degrees above that of
the radiant. [Column 3, lines 51-57.]
A portion of the air-gas mixture flows into the interior of
the
mantle 58 where it burns and heats the mantle.
The mantle is thereby heated to a temperature at
which it emits white light consisting primarily of
radiant energy having a wave length in the range of
0.4 to 0.7 micron. The white light radiates through
the apertures in radiators 48 and 50 and is
concentrated and projected in the desired direction
by reflector 56 in the form of a beam of intense
white light. [Column 4, lines 55-61.]
Looking first at the examiner’s rejection of claim 1, the
essence of the rejection is the examiner’s determination that
it would have been obvious to employ (1) a mantle of honeycomb
construction in either Thompson or Schade in view of
Hailstone, and (2) a diverter such as element 50 of Bryan in
either Thompson or Schade.
Appellant does not specifically dispute the examiner’s
