DEFINITION

Classification: 102/325

Contained pressurized fluid blasting charge:

(under subclass 301) Subject matter which includes a high pressure resistant container and a contained high pressure nondetonatable fluid which when suddenly released from the container, acts as a physical force to break up material.

(1) Note. Subcombinations of a nondetonating fluid blast cartridges are placed with the combination.

(2) Note. An inlet to the chamber is necessary to charge the chamber in order to have the gas or liquid within the chamber, but generally this inlet is not claimed.

(3) Note. Here are patents wherein a gas or liquid under pressure bursts the container to release the high pressure gas or liquid to a shot hole in which it is placed.

(4) Note. The term "fluid" includes gas and liquid.
