Abstract

Non-electric and non-explosive fuse-like initiating device which makes use of a process of propagation of a gaseous plasma generated by deflagration of a pyrotechnic material deposited as a layer on the inner surface of a supporting duct, employing transfer of thermal energy given by an instantaneous source of heat from one end to the other of the duct, for application in the art of blasting with a fuse-like function. The pyrotechnic mixture applied to the supporting duct is subjected to a suitable mixing process to ensure cohesive properties so that the mixture will adhere in the proper manner to the inner surface of the supporting duct and permit great flexibility in the density of the lining charge. Use of a pyrotechnic mixture to line the inner surface of the duct permits the use of a vast range of chemical substances. The initiating device in terms of the length and type of pyrotechnic mixture used may serve as a non-electric and non-explosive time delay fuse or perform a time delay function in addition to serving as a fuse device.
