DEFINITION

Classification: 400/216.5

Field selection by selectively positioned stop faces to limit vibrator movement:

(under subclass 215.1) Subject matter wherein an assemblage of elements for moving the vibrator* to change ribbon* zones includes a member having a surface which, during vibrator movement, is intended to contact an abutment surface on

another member, and wherein the extent of vibrator movement for zone selection is controlled by the position of said abutment surface.
