DEFINITION

Classification: 228/234.1

Specific mode of heating or applying pressure:

(under subclass 101) Process wherein a procedure of or an implement for applying thermal energy or force to the meeting faces of the work is set forth in a claim.

(1) Note. Cooling is considered to be "applying temperature."

(2) Note. Heating ancillary to welding in a furnace which may be disclosed, but NOT claimed, as electrically heated is included herein.

(3) Note. Heating by engulfing a work in a liquid or by a "wave" of liquid over a portion of work is included herein.
