device there necessarily is heat transfer that changes the
temperature of the air. See id. The examiner, however, has not
explained why the pressure and volume relationships of the air in
Shelton’s device are such that a temperature change of the air
necessarily takes place.
Consequently, we remand the application for the examiner and
the appellants to address on the record whether there necessarily
is a temperature change of the air in Shelton’s device.
The appellants’ claim 1 requires an interface device to open
the second end of the air hose when the second end is positioned
to provide pressurized air to the inlet port and to close the
second end when the second end is removed from the inlet port.
The examiner argues that the interface device is “the cap to the
right of figure 8” (final rejection mailed January 10, 2005, page
3). What the examiner refers to as a cap is a bag attachment
fitting through which air flows (col. 3, lines 60-61; fig. 8).
That fitting does not open the second end or close the second end
at all, let alone when, respectively, the second end is
positioned to provide pressurized air to the inlet port or is
removed from the inlet port.
