(under subclass 200.1) Apparatus wherein the motive fluid, as it leaves the ejecting means, substantially consists of a liquid.
(1) Note. The fluid leaving the ejecting means is considered to come under this definition if a substantial and important thrust component thereof is a liquid. A fluid not coming under the definition, for example, would be a gas containing a liquid mist. For such a fluid see subclass 264 for motive fluid treated with liquid, and subclass 227 for motive fluid which is principally steam.
(2) Note. The devices classified under this definition are usually boat propulsion devices in which the motive fluid leaving its ejecting means is disclosed as acting against an ambient liquid.
