Subclasses list

Definition

This class contains and is limited to:

1. Machines or structures adapted to be completely or partially sustained by the air (e.g., winged aircraft, helicopters, parachutes, kites, balloons, etc.),

2. Machines or structures adapted to be propelled and guided or stabilized through the air (e.g., projectiles with fins, guided missiles, etc.),

3. Machines or structures adapted to be placed in an orbit or which substantially operate outside the earth"s atmosphere (e.g., satellites, space vehicles, etc.),

4. Subcombinations of the machines or structures of 1-3, above, not classified elsewhere (guidance and control, aircraft structures, etc.),

5. Devices ancillary to the use of the machines or structures of 1-3 above, not classified elsewhere (e.g., mooring devices, etc.), and

6. Processes or methods peculiarly related to 1-5 above and not provided for elsewhere.

Lines with other classes and within this class

This class excludes toy or model aeronautical devices unless the invention is such that it also applies logically to full sized devices for actual use in carrying persons or cargo. For toy or model airplanes, etc., see Class 446, Amusement Devices: Toys, subclass 56.

This class excludes motor vehicles for travel on land or water, and which vehicles are supported above said land or water by a relatively thin cushion of air between the vehicle and the land or water, such cushion of air being generated by the motor vehicle (e.g., ground effect machines). For a motor vehicle of the surface effect type, see Class 180, Motor Vehicles, subclasses 116+.

This class provides, in subclasses 76+, the generic subclass for the automatic steering of mobile craft in two or three dimensions. See subclasses 175+ where the control apparatus includes electrical devices or apparatus. See the search notes to these subclasses for the other subclasses which provide for motion and/or steering control and a statement as to the line between the classes.

Arrangements of aircraft to permit their handling by hoists are found in this class, subclass 1. For similar arrangements on other articles, see Class 220, Receptacles, subclass 1.5+ and Class 294, Handling: Hand and Hoist-Line Implements, subclass 74, and indented subclasses.

Gas cells or balloon envelope distinguished only by the coating on, or by the structure of the fabric or textile are placed in Class 428, Stock Material or Miscellaneous Articles, appropriate subclasses; see especially subclasses 175+, 190, 193, and 196+ for a single or plural layer sheet or web embodying mechanically interengaged strands (e.g., weave or knit), and subclasses 411.1+ for a composite, web or sheet characterized only by the composition of the layers.
