DEFINITION

Classification: 244/3.1

(under the class definition) Subject matter including means which operates inherently to compensate for undesired changes in attitude or which operates to affect the trajectory or course of an unmanned aerial missile.

(1) Note. The term "missile" in the above definition includes: (a): (1) a device explosively propelled through and from the barrel of a gun or (2) a device carrying an explosive which explosive when actuated either (a) detonates to destroy or damage the carrying device, or (b) burns or combusts within the carrying device to (1) release the products of combustion to the atmosphere, or (2) generate a gas to eject an object or substance from the carrying device, or (3) generate heat within the carrying device which damage or partly damages the carrying device; (b) a device having a payload and an attached reaction motor for propelling payload through the earth's atmosphere. The reaction motor comprises a means for producing a motive fluid and a means for ejecting said fluid (see 1-8 Notes Class 60, Power Plants, subclasses 200.1+).

(2) Note. This definition excludes aircraft which are sustained by air. For such subject matter see this class, subclasses 4+.

(3) Note. Where the "missile" is disclosed as having utility for manned flight the patent is excluded under this definition and is classified in this class, subclasses 75+.

(4) Note. Where the "missile" (manned or unmanned) is (1) disclosed as a body which is to be placed in orbit around the earth (i.e., satellite) or (2) solely disclosed as a vehicle for use in outer space interplanetary travel, it is classified in this class, subclass 1.

(5) Note. This definition excludes explosive devices designed to be dropped from the air or watercraft on an objective below, known as "drop bombs". Such subject matter is classified in Class 102, Ammunition and Explosives, subclasses 382+. (6) Note. This definition excludes a missile having a payload for display or amusement (e.g., fireworks or toy novelties) with a reaction motor driven by the products of combustion. Pyrotechnic rockets are classified in Class 102, Ammunition and Explosives, subclasses 347+.

(7) Note. This definition further excludes a pyrotechnic (firework creating flash, noise or smoke) device of general utility having a vane, a wing, parachute, balloon or propeller. Such subject matter is classified in Class 102, Ammunition and Explosives, subclasses 335+ and 367+.

(8) Note. This definition further excludes a rocket having a toy, amusement or display (nonpyrotechnic) payload with a reaction motor driven by other than products of combustion. Such a rocket is classified in Class 446, Amusement Devices: Toys, subclass 56.
