Note(s)

  1. In groups B63B 1/00-B63B 11/00, B63B 15/00-B63B 19/00, B63B 39/00-B63B 43/00, B63B 49/00, B63B 59/00, 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 the different types of indexing code.  [6]
