- 8. The apparatus as described in claim 2 wherein:
- said outer region is manufactured of an intumescent material.
- 9. The apparatus as described in claim 3 wherein:
- said outer region is manufactured of an intumescent material.
- 10. The apparatus as described in claim 4 wherein:
- said outer region is manufactured of an intumescent material.
- 11. The apparatus as described in claim 5 wherein:
- said outer region is manufactured of an intumescent material.
- 12. The apparatus as described in claim 6 wherein:
- said outer region is manufactured of an intumescent material.
- 13. The apparatus as described in claim 1 wherein:
- said inner region is manufactured of an intumescent material.
- 14. The apparatus as described in claim 2 wherein:
- said inner region is manufactured of an intumescent material.
- 15. The apparatus as described in claim 3 wherein:
- said inner region is manufactured of an intumescent material.
- 16. The apparatus as described in claim 4 wherein:
- said inner region is manufactured of a non-intumescent material.
- 17. The apparatus as described in claim 1 wherein:
- said outer region is manufactured of a non-intumescent material.
- 18. The apparatus as described in claim 2 wherein:
- said outer region is manufactured of a non-intumescent material.
- 19. The apparatus as described in claim 3 wherein:
- said outer region is manufactured of a non-intumescent material.
- 20. The apparatus as described in claim 4 wherein:
- said outer region is manufactured of a non-intumescent material.
