  B63H 20/00 - B63H 25/52  

SECTION B – PERFORMING OPERATIONS; TRANSPORTING


B 63SHIPS OR OTHER WATERBORNE VESSELS; RELATED EQUIPMENT


B 63 HMARINE PROPULSION OR STEERING (peculiar to submarines, other than nuclear propulsion, B63G; peculiar to torpedoes F42B 19/00)


Notes

(1)In groups B63H 1/00, B63H 5/00, B63H 9/00, it is desirable to add the indexing code relating to individual components of surf-boards. The indexing code, which is from group B63B 35/79, has the same number as the classification symbol, but a colon is used instead of the oblique stroke, and should be linked.  [5]

(2)Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of different types of indexing code.  [6]
