Abstract
770,194. Blasting apparatus. MACCARTHY, C. P. Feb. 16, 1955 [June 12, 1954], No. 17330/54. Classes 9 (1) and 68 (1). [Also in Group XXVIII] opening into a pipe a of a water infuser tube is a chamber c through which moves a piston d, d<SP>1</SP>. Water is fed into the pipe a through a valve h, which is automaticaMy closed on the pressure of the water in the tube a exceeding that of the supply mains, and passes out of the pipe a, which 'is sealed into a bore hole n in a mineral face o to impregnate the face by a resilient sleeve m. When the face is completely impregnated the pressure of the water therein is increased by firing an explosive charge in a chamber c at the end of the chamber c, the piston d, d<SP>1</SP> 'being driven through the chamber c.
