DEFINITION

Classification: 60/244

(under subclass 200.1) Apparatus (A) which by relative rearrangement or adjustment of its parts or by the addition or omission of a part is so changed as to become (1) basic subject matter of this class as defined in subclass 200.1 of a different character or having a different mode of operation or (2) basic subject matter of another class, or (B) in which the apparatus as defined in subclass 200.1 is combined with means, which means if claimed, per se, would be classified in another class and which is not merely a part or subcombination of the apparatus.

(1) Note. In this subclass, for example, are apparatus having means by which motive fluid may be produced by two or more diverse producing means and ejected through a single ejecting means, and having means by which motive fluid from any one of the diverse producing means may be ejected through the ejecting means to the exclusion of the motive fluid produced by another diverse motive fluid producing means.

(2) Note. A mere fuel or ignition control means by which one motive fluid producing means may function to the exclusion of another diverse fluid producing means is not included in this definition. These apparatus may be found in subclasses 224, 250, 261.

(3) Note. The following are examples of diverse motive fluid producing means: ram air fed combustion products generator (athodyd), mechanically compressed air fed combustion products generator, resonating combustion chamber, pulsating valve controlled combustion products generator; mechanically compressed air, non-air breathing combustion chamber, ion acceleration, electrical or wave energy heating

means, sublimation, etc.

(4) Note. Motors having plural means for the production of a motion fluid for ejection through a single nozzle wherein one means may not function to the exclusion of another of the means are found elsewhere. See, in particular, subclass 262 for combustion products generators with ambient air bypass means.

SEE OR SEARCH THIS CLASS, SUBCLASS: 224+, for devices considered to be interrelated motors which may comprise a single casing housing diverse motive fluid producing means but employing distinct exhaust nozzle configurations for the motive fluid issuing from each motive fluid producer.

261, for motors having an after burner (i.e., a nonpropellant combustor) which may be diverse from a primary combustion products generator, but wherein the primary combustion products generator and afterburner are operated exclusively only through fuel or ignition control of either.
