Note(s) This sub-class covers, in general, any means for discharge or outflow of liquids, whether by gravity, under pressure, or otherwise, and similar means for discharge of gases and of other fluent substances, such as powders, granular materials, short fibres, and fluent pastes. Accordingly, the term "liquid" is to be read as covering such other substances and also suspensions of such substances in true liquids or in air. It is particularly concerned with the release or projection of drops or droplets into the air or into a chamber, e.g. to be deposited on surface, to form a mist. For this purpose, the substance to be projected may be suspended in a stream of air, or of other gas or vapour, which is to be understood as covered by the term "air

Note(s) This sub-class deals with apparatus for covering a surface or a part of a surface with liquid by any mechanical or physical method and for any purpose, e.g. coating, impregnating, washing, and is particularly concerned with obtaining a uniform distribution of liquid on a surface. It also covers apparatus for dealing similarly with other spreadable substances such as pastes, and the term "liquid" is accordingly to be read as covering such other substances
