Abstract
484,098. Blasting - cartridges. TAYLOR, J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 29, 1936, No. 29474. [Classes 9 (i) and 9 (ii)] Relates to blasting-cartridges of the kind comprising a pressure-resistant re-utilizable container charged with a solid material capable of undergoing a non-detonating gas-producing decomposition after being locally initiated, the container being closed by a breakable seal. According to the invention, a quantity of sand or like granular substance having the property of packing under pressure is inserted to fill the space between the charge and the seal, and the seal is adapted per se to yield to an internal pressure substantially higher than atmospheric pressure but considerably less than the pressure at which the container will actually vent, the quantity of packing granular material determining the extra ressitance to venting, which must, however, occur before any deformation or damage is done to the container by internal pressure. Suitable charges are described in Specifications 431,935, 436,144, 453,210, 461,647, and 481,166. Suitable initiating devices are described in Specifications 430,750 and 431,950. Specification 430,258 also is referred to.
