(under the class definition) Sealing means including means to react to a change in a measure of warmth or coldness.
(1) Note. This and indented subclasses do not include a seal that merely accommodates thermal expansion between parts.
SEE OR SEARCH THIS CLASS, SUBCLASS:
359+, for a relatively rotatable, radially extending, sealing face member (e.g., face, mechanical, etc.) having a temperature responsive feature.
471, for a particular piston ring expander having thermal expansion means.
SEE OR SEARCH CLASS
285, Pipe Joints or Couplings, for means to secure in end-to-end or side-to-side relationship a pipe to another pipe, a plate, a wall, a receptacle, or other base where the means are independent from a seal (i.e., more than the frictional engagement of the seal secures a pipe end to another part) or a sleeve securing the pipe ends or another part;
187, for temperature responsive means to maintain a good seal for expansion or contraction in the pipe coupling.
