Abstract
Official abstract text for this publication.
A method of sealing includes positioning graphite within a cavity defined by walls of a body, shifting the body along a tapered surface of a first structure, expanding the body through an interaction with the tapered surface, engaging at least one second structure with the walls, expanding the graphite, compressing the graphite against the at least one second structure, and sealing the graphite to the at least one second structure and the body.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of sealing, comprising: positioning graphite within a cavity defined by walls of an annular body; shifting the annular body along a tapered surface of a first annular structure; expanding the annular body through an interaction with the tapered surface; engaging at least one second annular structure with the walls; expanding the graphite radially outwardly through the interaction of the annular body with the tapered surface; compressing the graphite against the at least one second annular structure; and sealing the graphite to the at least one second annular structure and the annular body. 2. The method of sealing of claim 1 , further comprising maintaining the graphite within the cavity. 3. The method of sealing of claim 1 , further comprising resiliently compressing the graphite within the cavity. 4. The method of sealing of claim 1 , further comprising resiliently compressing a resilient member other than the graphite within the cavity. 5. The method of sealing of claim 1 , further comprising altering a temperature of the graphite to cause it to expand. 6. The method of sealing of claim 1 , further comprising increasing a volume of the cavity. 7. The method of sealing of claim 1 , further comprising maintaining the annular body longitudinally fixed in relation to the at least one second annular structure while expanding the annular body. 8. The method of claim 1 , wherein the step of positioning the graphite within the cavity defined by the walls of the annular body includes positioning a graphite slab between two adjacent graphite slabs that define the walls. 9. The method of claim 1 , wherein the step of positioning the graphite within the cavity defined by the walls of the annular body includes the cavity having a U-shaped cross-section. 10. The method of claim 1 , wherein expanding the graphite includes increasing a volume of the graphite between about 50% and about 200%.
