.~.~.~ Circumferential or circumferentially spaced
DEFINITION
Classification: 188/73.2
(under subclass 73.1) Apparatus wherein said component includes either a single friction surface or a plurality of separate friction surfaces, but in either case extending entirely around the axis of rotation of the member which the surface will contact.
(1) Note. Included in this subclass are disclosures of a conical or frustro-conical surface, or of a planar radial surface, as well as segments of surface portions spaced circumferentially to form an equivalent conical or planar ring.
(2) Note. The component referred to herein is the stator.

71.5, for disclosure of a multiple-disc brake assemblage using annular brake disc and complementary annular rotating
members. 218, for rotor or stator structure, per se.
