  • Patent number: 4173932
    Abstract: A safety shutter for use in ordnance fuzes and the like consisting of two more metal plates in contact, with each region of contact shaped so that the plates are touching, or nearly touching, only at isolated points or small regions over the confronting faces so that there are six spaces between and intermingled with the areas of contact of the plates such that the broken interfaces between the plates interrupt the transmission of a shock wave capable of inducing spalling from the surface of the shutter which faces the secondary explosive thereby preventing accidental initiation of a propagating detonation. The broken interfaces also absorb the energy of an inadvertently functioned detonator by local crushing and shearing of the metal protuberances on each of the confronting faces of the plates.
