.~.~ Vane structure (i.e., flight guiding or stabilizing means)
DEFINITION
Classification: 473/586
Vane structure (i.e., flight guiding or stabilizing means):
(under subclass 578) Subject matter either(a) consisting of the feathering or other flight guiding, retarding, stabilizing, or controlling means, per se, of an elongated missile intended to have such feathering or other flight guiding, etc. means, or (b) relating to the feathering or other flight guiding, retarding, stabilizing, or controlling means of an elongated missile having such feathering or other flight guiding, etc. means whenever significance is attributed to such feathering or other flight guiding, etc. means, which feathering or other flight guiding, retarding, stabilizing, or controlling means is intended to (1) maintain the missile airborne or aloft for longer periods of time, (2) stabilize the missile, (3) provide aerodynamic drag upon the missile, or (4) cause the missile to produce one or more aerodynamic actions typical of aircraft.
(1) Note. A document, in order to be placed in this subclass, must claim significant feathering, vane, or other flight guiding, retarding, stabilizing, or controlling structure. Such feathering, vane, or other flight guiding, retarding, stabilizing, or controlling structure merely named in a claim or merely disclosed in a document is not sufficient to place a document in this subclass.
