Appeal No. 2000-0803
Application 05/333,233
As explained on page 1 of the specification, an object of
appellant’s invention is “to provide a shaped beam of infrared
radiation from a combustion heated honeycomb mantle in
combination with a reflector.” To this end, the invention
includes an infrared radiation source comprising a honeycomb
mantle which is closed at one end and heated with combustion
gases applied to the other end, and a diverter disposed on the
closed end of the mantle to divert the combustion gases and,
thus, provide uniform heating of the mantle (specification,
page 1, line 25, through page 2, line 4).
Claim 1, the sole independent claim on appeal, is
representative of the appealed subject matter and reads as
follows:
1. A combustion heated honeycomb mantle infrared
radiation source comprising:
a combustion heated mantle formed of a material
which when heated emits radiant energy, said mantle
including walls of a honeycomb structure with the
axis of symmetry of the holes of said honeycomb
walls being disposed at an angle of less than 180E
with respect to the longitudinal axis of said
mantle, said mantle being open at one end and closed
at the other end;
a diverter disposed at the closed end of said
mantle; and
