Appeal 2006-3282
Application 09/683,353
INVENTION
Appellant’s invention relates to an apparatus for indicating the
temperature of a material, useful in welding. The invention includes a
connector for holding a pair of temperature indicator sticks, where each
indicator stick melts at a different temperature. These indicator sticks are
rated to measure a given temperature, which is generally not the same value,
during welding, heat treatment, and metal fabrication processes. The
connector is further configured to removably hold the indicator sticks
together, and includes a convenient pocket clip.
Claims 1 and 16 are representative of the claimed invention and are
reproduced as follows:
1. A dual temperature indicator stick assembly comprising:
a first indicator stick housing positioned along a first axis and
configured to hold a compound which melts at a first given
temperature;
a second indicator stick housing positioned along a second axis
and configured to hold a second compound which melts at a second
given temperature; and
a one-piece connector physically connecting the first and
second indicator stick housings along different axes.
16. A dual temperature indicator stick apparatus comprising:
first means for indicating a first temperature;
second means for indicating a second temperature; and
