    摘要: Modified organic isocynate composition containing urea and/or biuret groups, and/or salts of these groups, prepared by reacting a blocked amine composition and a polyisocyanate composition, said blocked amine composition being the reaction product of :

    a. a primary and/or secondary organic amine composition having an average amine functionality of at least 0.1 and an average total active hydrogen functionality of from about 1.5 to about 10.0, and
    b. a reactivity modifying agent selected from proton acids, Lewis acids, silylating agents, metallating agents and alkylating agents, and said polyisocyanate composition comprising organic polyisocyanates and/or polyisothiocyanates having a reactive isocyanate and/or isothiocyanate functionality of at least 1.0, the reaction between said blocked amine and polyisocyanate compositions being conducted so as to provide an excess of isocyanate and/or isothiocyanate groups over total active hydrogens in the blocked amine composition of at least 1.5 : 1.0.

    摘要: An impact sensitive detonator, particularly suitable for the initiation of explosive charges in oil wells, comprises a cylindrical casing (10,110) closed at one end and open at the other end, the closed end having a thin striking surface (22,122) which deforms without rupture when struck by a rounded firing pin (60). The casing contains a primary explosive charge (50) preferably lead azide, adjacent to the closed end, a mass of finely divided refractory material (52), for example silicon carbide adjacent to the primary expolsive charge and an impact member (40, 140), extending transversely across the casing and forming with the casing a confined space for the primary explosive charge and the refractory material. The refractory material and the impact member aid the initiation of the primary explosive charge. Optionally a second charge of primary explosive may be placed on the output side of the impact member. Preferred forms of the detonator contain an output charge (56) of high explosive, for example, hexanitrostilbene between the impact member and the open end of the casing.
