.~ Device including linearly-aligned power stream emitter and power stream collector
DEFINITION
Classification: 137/842
(under subclass 803) Device provided with at least two passages joined at a zone common to both passages, including a first passage permitting entry into said common zone of a power input stream of fluid and a second passage permitting exit from said common zone of a power output stream of fluid, said passages each extending along a line common to both passages.
(1) Note. The diversion or alteration required by the definition of subclass 803 is not referred to in the definition of this subclass because there are many different ways of accomplishing the diversion in the devices of this subclass, but the diversion nevertheless is present. Among the ways of accomplishing the diversion are an enlarged interaction chamber, a passage for control-input signal, a plurality of power output passages lying in a common plane and a passage for control-input signal perpendicular to said common plane, and a restricted interaction region to which control-input signal is applied, these being only exemplary of devices found.
