DEFINITION

Classification: 165/104.26

Utilizing capillary attraction:

(under subclass 104.21) Apparatus including a tubelike passage for flow of the retained body of material while in the liquid state, wherein the passageway is sufficiently small such that the surface tension of the material serves to influence the flow of material passing therethrough.

(1) Note. The capillary flow of this subclass is deemed to be inherent in the design of the structure, as in the case of provision for gravity flow, and the capillary tube is not therefore considered to be means to move the retained liquid material.

(2) Note. A "heat pipe" with a capillary passageway or wicking material therein is considered to involve a change of state.

104.22, for similar structure wherein flow of the retained material is caused by mechanical means in engagement therewith.
