Abstract

Signalforsinkelsesanordning for bruk ved overforing av sprengningssignal og som omfatter en tenningsbuffer (45) for en forsinkelseskjede og som er plassert mellom et over- føringsrør (11) og forsinkelseskjeden (25) i et detonator- hylster eller et hylster for et signaloverføringsrør. Denne buffer er innrettet for å regulere i hvilken grad over- føringsrørets temperatur/trykk-puls påføres forsinkelses- kj edens pyrotekniske overflate, idet virkningen av denne puls svekkes med den følge at forbedret tidsforsinkelsesnøyaktig- het oppnås. Bufferen sørger også for å dempe virkningene av plutselig trykksenkning inne i detonatoren, og som kan skrive seg fra brudd på overføringsrøret eller utstøtning av dette rør fra huset. Derved hindres oppstykning av det reagerende pyrotekniske material, som ellers ville kunne frembringe stans i reaksjonen på oppstykningsstedet, samt derved sette forsinkelseskjeden ute av stand til å fortsette forbrenningen av den pyrotekniske materialsammenstilling over hele sin lengdeutstrekning.
