Appl. No.:
5/612817
Inventors:
Bruce Bartels - Ridgecrest CA John W. Holtrop - Ridgecrest CA Larry L. Liedtke - Ridgecrest CA Russell T. Trovinger - Ridgecrest CA
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
F41F 104
US Classification:
89 7
