DEFINITION

Classification: 60/224

(under subclass 200.1) A plurality of apparatuses, each, interrelated (1) by a single means to which two or more responds, or (2) by a means or condition in one of the apparatuses upon which another apparatus is dependent for its operation.

(1) Note. A plurality of apparatuses under this definition must each include an individual means for placing its motive fluid under pressure and an individual means for ejecting said fluid. However, a device, e.g., a fan jet, having a unitary device employed to pressurize fluid for two or more ejecting means comes within this definition provided the fluids for each said ejecting means are distinguishable and not intermixed as they are being pressurized or before entering said ejecting means.

(2) Note. Concentric nozzles are not considered plural individual means for ejecting fluid if fluid from one nozzle is discharged within the confines and upstream of the discharging extremity of another of the nozzles.

(3) Note. This definition includes one reaction motor which is controlled in response to the output of another reaction motor.

(4) Note. This definition includes devices in which a component of one reaction motor is effective to operate a component (e.g., compressor) of another reaction motor.

(5) Note. A reaction motor having means by which ambient

air is conducted to cool a motor part (e.g., air conducted to cool a combustion chamber, and thereafter discharged to the ambient through a nozzle, and wherein there is no disclosed indication that the coolant air may produce a thrust) is not subject matter for this subclass. Such devices may be found below particularly in subclass 266. SEE OR SEARCH THIS CLASS, SUBCLASS:

229, for reaction motors wherein motive fluid from a common source may be ejected selectively through one or more of several ejecting means.

244, for devices having a single exhaust nozzle for sequentially ejecting motive fluid produced by diverse motive fluid producing means.

262, for a device having plural means each forming a compressed gas stream, e.g., a fan-jet, wherein at least two of the streams are combined before being discharged through a common ejecting means.

263, for devices in which the fluid from a single motive fluid pressurizing means is separated into several paths of fluid, wherein two or more of said paths are each ejected through separate ejecting means.
