| DefinitionThis is the generic class for a sealing means or a process of using a seal to act at a joint or juncture of adjacent parts to oppose passage of a fluid. The sealing means or process: (1) closes a space formed between or (2) deflects the fluid away from the joint or juncture by using the fluid, another fluid, or an article. (1) Note. For a seal that does not claim a static or dynamic use, it is permissible to use its disclosure for placement. | Lines with other classes and within this class In Class 520, Synthetic Resins or Natural Rubbers, subclasses 1+ are the generic subclasses for a synthetic resin or natural rubber preparation, and composition containing or treatment thereof is to be considered an integral part of Class 260 retaining all pertinent definitions and class lines, and having Classes 521, 522, 523, 524, 525, 526, 527, and 528 indented thereunder. |
