DEFINITION

Classification: 165/104.15

Solid fluent heat exchange material:

(under subclass 104.11) Apparatus wherein the retained body of material which acts to receive and discharge heat exists, at least during part of the normal operation of the apparatus, in the solid state.

(1) Note. The solid heat exchange material of this subclass may be pelletized or particulated so that flow takes place. For placement herein, it is required that there be flow of the material, not just movement. For example, included herein is an apparatus having a conveyor that dumps the heat exchange material thereby allowing it to flow, whereas an apparatus that carries similar material continuously is excluded since at no time is the material allowed to flow.

(2) Note. The retained body of material may be fluent when in the liquid state and may be nonfluent when in the solid state but must be solid at least during part of the normal operation of the apparatus.
