Abstract
A high temperature superconducting bearing including a permanent magnet rotor levitated by a high temperature superconducting structure. The rotor preferably comprises a plurality of concentric permanent magnet rings coupled to permanent magnet ring structures having substantially triangular and quadrangular cross sections. Both alternating and single direction polarity magnet structures can be used in the bearing.
Claims
AMENDED CLAIMS
[received by the International Bureau on 16 April 1996 (16.04.96); original claims 15-25 cancelled; original claims 11-14 amended; remaining claims unchanged (1 page)] quadrangular cross-section and comprising a plurality of substantially square structures and a plurality of substantially triangular structures.
9. The bearing as defined in Claim 8, wherein at least one of said first permanent magnet ring structures and said second permanent magnet ring structure comprises permanent magnet structures abutting concentric bands.
10. The bearing as defined in Claim 8, further including concentric bands abutting said permanent magnet rings.
11. The bearing as defined in claim 10, wherein said concentric bands are dimensioned to compress said permanent magnet rings.
12. The bearing as defined in claim 10, wherein said concentric bands comprise a composite material.
13. The bearing as defined in claim 10, wherein said concentric bands comprise steel.
14. The bearing as defined in claim 10, wherein said concentric bands comprise a plurality of steel wires.

STATEMENT UNDER ARTICLE 19
Responsive to the International Search Report dated 29 February 1996, Applicant submits amendments to the abstract, specification, and claims under Article 19 and pursuant to Rule 46. Consideration and entry of the amendments is respectfully requested.
The amendments presented herewith are intended to parallel those to be made to the abstract, specification, and claims of the corresponding United States application. Claims 1-10 remain unchanged. Claims 11-14 have been replaced by amended claims bearing the same respective numbers.
The amendment presented herewith does not introduce new matter. The amendment is fully supported by the specification originally filed as part of the application.
Applicant has reviewed the International Search Report before preparing the present amendment. The documents cited in the report are also cited in the corresponding United States prosecution. The claim amendment is believed to clarify and patentably distinguish the Applicant's invention over the referenced documents.
Please refer to the accompanying letter, as required under Rule 46.5(a), for an explanation as to the abstract, specification, and claim amendments and replacement sheets hereby filed.
