Appeal No. 96-0661
Application 08/189,833
is indicated that the heating element
therein may be mainly composed of powdered carbon and silicon
carbide mixed and proper metal particles such as alumina
powder, and column 9, lines 21-28, which notes that a heating
element of
the composition disclosed in Matsubara is capable of attaining
a temperature of about 1000ºC, a temperature well within
appellant’s claimed range.
Appellant’s apparent belief that the applied references
must teach or suggest compositions for the heating elements
therein that would allow for temperature variations covering
the entire range of about 30ºC to about 2000ºC, and
particularly the upper temperature level of about 2000ºC, is
misplaced given the broad recitations in claims 1 and 5 on
appeal. These claims merely require that the heating element
be "mainly made of carbon powder, alumina powder and silicon
carbide powder in proportions preselected to provide an
operating temperature in the range of about 30ºC to about
