Classification: 102/301


(under the class definition) Apparatus and corresponding methods involving the breaking up or the destruction of natural or man-made objects or material by the use of a fluid under high pressure including means for (a) the sudden release of the fluid under high pressure resulting from a chemical reaction, or (b) a very rapid escape or release of the fluid under high pressure.

(1) Note. This and the indented subclasses include accessories, e.g., mats, plugs, etc., or subcombinations specialized in blasting.

(2) Note. This group of subclasses does not include ammunition for weapons. See "SEARCH THIS CLASS, SUBCLASS", for notes to subclasses.

(3) Note. The objects or material broken up or destroyed may be above or below the ground or underwater.

(4) Note. The blasting may be for mining, excavation, or demolition purposes. See "SEARCH CLASS" notes for classes.
