(under subclass 12) Subject matter in which both a fluid actuator and an actuator other than one utilizing fluid are provided for alternative use.
(1) Note. Actuators which include both fluid actuation mechanism and non-fluid actuation mechanism but in which said mechanisms are not of themselves each capable of fully controlling the valve are not considered to be alternative within the scope of this subclass and are classified in an appropriate subclass for the fluid actuation mechanism and cross referenced for novel nonfluid actuation mechanism. Examples of such excluded devices are electrically controlled pilot valves in subclass 30 and manually opened and fluid pressure closed valves in subclasses 48+.
SEE OR SEARCH THIS CLASS, SUBCLASS:
30, for electrically controlled fluid actuators, and see (1) Note.
48+, for manually opened, fluid pressure closed valves and see (1) note.
130, for electrical actuators combined with a nonfluid, nonelectrical actuator.
