Notes

(1)

In groups B 63 B 1/00 to B 63 B 11/00, B 63 B 15/00 to B 63 B 19/00, B 63 B 39/00 to B 63 B 43/00, B 63 B 49/00, B 63 B 59/00, it is desirable to add the indexing code relating to individual components of surf-boards. The indexing code, which is from group B 63 B 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]

Hydrodynamic or hydrostatic features of hulls or of hydrofoils (hulls peculiar to submarines B 63 B 3/13; keels B 63 B 3/38; determining hydrodynamic or hydrostatic features B 63 B 9/00; decreasing pitch, roll, or like unwanted vessel movements by using foils acting on ambient water B 63 B 39/06)
