    Abstract: 12,463. Weber, W. Aug. 30. [Addition to 8606/15.] Blasting-cartridges. -Relates to "liquidair " blasting-cartridges containing separa.te charges of metallic powder and combustible absorbent respectively as described in the parent Specification, and consists in the use of a mixture of several metallic powders instead of a single one. A small amount of combustible absorbent, such as amorphous carbon, may be added to the metallic powders.

    Abstract: 8606. Weber, W. June 10. Blasting- cartridges.- Relates to cartridges containing an absorbent material for liquid air, a metallic powder, and a primer, and consists in separating the metallic powder from the absorbent and using it in Small proportions such as /10 th. As shown, the cartridge comprises a double-walled outer casing a, an inner perforated tube b, a charge d of combustible absorbent such as cotton, cork, sawdust or linen, and a charge c' of metallic powder such as aluminium and a detonator c in a bag c. Corrugated paper is inserted between the walls of the casing a, and longitudinal grooves covered with paper are provided for the wires p of the detonator. The charges are inserted from the bottom, which is then closed up by a cap f ; and the liquid air is poured in down the tube b, which is then closed by a plug g. The cartridge is then inserted in the bore hole, the hole tamped--vent holes being left through the tamping by means of skewers-and the shot fired. Liquid air may also be allowed between the double walls of the cartridge. The bore hole may be cooled by liquid air before the insertion of the charge.

    Abstract: 11,479. Weber, W. Aug. 9. Blasting- cartridges.- Relates to blasting-cartridges formed by an absorbent impregnated with liquid air after insertion in the bore-hole, and consists in tamping the bore-hole with a loose earthy matter c in a paper case covered by a loose plug d of wood provided with one or more plate springs g which grip the sides of the bore-hole, so that any air that evaporates can leak past the stopper, while the springs prevent the tamping from being blown out.
