DEFINITION

Classification: 165/104.22

Including means to move heat exchange material in liquid state:

(under subclass 104.21) Apparatus provided with means to act to force the retained body of material, while in liquid state, to flow.

(1) Note. Structure utilizing gravity, steady-state centrifugal force, or capillary attraction is not considered to be provided with means to move the retained body of material. Structure generating centrifugal force to cause material to flow is included herein.

(2) Note. A thermosiphon for causing the material to flow is considered to be a means for moving heat exchange material.

SEE OR SEARCH THIS CLASS, SUBCLASS:

104.21, for similar apparatus wherein liquid heat exchange material moves by the effect of gravity.

104.26, for similar apparatus wherein liquid heat exchange material moves by capillary attraction.

104.28, for similar apparatus wherein the liquid heat exchange material does not change state during operation of the apparatus.
