(under subclass 230) Apparatus having means whereby a fluid is injected into the motive fluid stream to change the direction of flow of said motive fluid.
(1) Note. Normally devices under this subclass have a secondary fluid injected into the motive fluid at a point upstream of the nozzle outlet. However, the subclass may also include patents disclosing means to inject secondary fluid into the motive fluid downstream of the nozzle outlet if the disclosure states that the deflected motive fluid is effective to alter the direction of thrust.

137, Fluid Handling,
803+, for means to divert or vary the flow of one stream relative to a steam receiver (1) direct contact with at least one other stream or (2) by application of an energy field directly to a stream. Devices known in the art as "fluid amplifiers" and which act to control or vary high energy flows by relatively low energy flow or fields are here included.
239, Fluid Sprinkling, Spraying, and Diffusing,
265.23, for reaction motor discharge nozzles in which the main discharge stream is deflected by a redirected portion of said stream, and subclass 127.3 for mixing a secondary fluid in the main stream.
