.~ Combustion is confined chamber having restricted discharge orifice
DEFINITION
Classification: 175/14
(under subclass 11) Subject matter in which an exothermic chemical reaction is caused to occur in a confined area, and
the products of the reaction are discharged through a restriction from said area against the mineral body with jet and/or intensely heated characteristics.
(1) Note. The "confined area" consists of an area enclosed by structure other than the mere walls of the borehole being formed in the mineral body.
