Abstract

416,586. Blasting-cartridges. FLEMING, J. S. B., 69, Eglinton Road, Ardrossan, Ayrshire, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. March 14, 1933, No. 7766. [Class 9 (i).] A flexible safety sheathing for blasting- cartridges or charges is made by incorporating a fibrous bonding material with a preponderating proportion of cooling salt or salts. The fibrous material may be a cellulose pulp, or carded or pulped cotton textile, or asbestos fibre, or Kraft pulp, and may constitute 2 to 10 per cent of the total dry ingredients of the sheath. Any of the well known cooling salts may be used, such as calcium fluoride, sodium fluoride, sodium chloride, and sodium carbonate, and mixtures of such salts. The ingredients are impregnated wet in various ways and then dried at 40‹ C. or more if the solubility of the salts does not greatly increase with rise of temperature. From 1 to 5 per cent of moisture may be left in the material. If the sheath is thicker than 0À05 inch, it may be convenient to groove it on one side to facilitate its folding round the explosive.
