Abstract

501,119. Blasting - cartridges. SOC. ANON. D'ARENDONCK. Aug. 25, 1938, No. 25018. Convention date, Sept. 22, 1937. [Class 9 (i)] A sheath for safety cartridges for mines is formed by rolling a band b of paper impregnated with a solution of extinguishing salts on a mandrel, the band being formed with an enlarged outer portion c. After thus rolling the band, the lower edge d of the portion c is folded over so as to close the lower end of the roll and the space a is packed with explosive. The upper edge d. of the portion c is then folded over to close the upper end of the roll and may be glued in position. The solution of extinguishing salts may consist of a solution comprising 20 parts by weight of potassium sulphate and 30 parts by weight of ammonium sulphate in 100 parts by weight of water.
