Abstract
687,663. Electric blasting fuzes. DYNAMIT-AKT.-GES. VORM. A. NOBEL & CO., and HABBEL, F. Nov. 1, 1949, No. 27979/49. Class 9(i) A delay electric blasting detonator containing a secondary charge the sensitivity of which is reduced by the addition of inert material as described in Specification 687,660 has a primary charge pressed into the lower part of a delay tube between the electric fuze and the detonator.
