Abstract
Abstract There is disclosed a termination device which includes a dimensionally heat-unstable tubular member and a dimensionally heat-unstable insert. The insert is positioned within the tubular member and is in abutting relationship therewith. The termination device may further include a fusible insert or inserts which may be thermoplastic polymeric materials or solder or both. The dimensionally heat-unstable insert is recoverable and the fusible insert or inserts, if present, are meltable at a temperature used to recover the dimensionally heat-unstable tubular member.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
113 words
A termination device comprising: a dimensionally heat-unstable tubular member having a wall, a fusible insert and a dimensionally heat-unstable insert; wherein dimensionally heat-unstable refers to said tubular member and said heat-unstable insert having plastic or elastic memory which defines the property of certain materials as being unstable at higher temperatures so that when the materials are exposed to this higher temperature, the materials return to their heat-stable shape; said fusible insert and said dimensionally heat-unstable insert positioned within said tubular member and in abutting relationship with the wall of said tubular member; said fusible insert being meltable and said dimensionally heat-unstable insert being recoverable at a temperature used to recover said tubular member.
Claim 2
Dependent Claim
113 words
A termination device comprising: a dimensionally heat-unstable tubular member having a wall, a fusible insert and a dimensionally heat-unstable insert; wherein dimensionally heat-unstable refers to said tubular member and said heat-unstable insert having plastic or elastic memory which defines the property of certain materials as being unstable at higher temperatures so that when the materials are exposed to this higher temperature, the materials return to their heat-stable shape; said fusible insert and said dimensionally heat-unstable insert positioned within said tubular member and in abutting relationship with the wall of said tubular member; said fusible insert being meltable and said dimensionally heat-unstable insert being recoverable at a temperature used to recover said tubular member.
