    • 1. In a mine adapted to be implanted in the soil, said mine including an explosive charge and a cavity therethrough; an upwardly biased active member slidably mounted in said cavity; a downwardly biased preventive pressure member slidably mounted in said cavity, said preventive pressure member having a greater area than said active member; a firing mechanism for exploding said mine mounted in said mine and adapted to be activated by said active member upon a downward pressure applied thereon, and said preventive pressure member acting upon an air blast above the soil to prevent said active member from activating said firing mechanism.

    • 1,176,352. Land mines. INDUSTRIEWERKE KARLSRUHE, A.G. 9 Feb., 1967 [16 April, 1966], No. 6267/67. Addition to 1,005,388. Heading F3A. The land - mine of parent Specification 1,005,388 is modified by a cover member 3 having a spherical surface 51 with a centre of curvature which lies above the mine body, or in an upper part thereof, and which is supported by an annular member with an upper web 52a, having a conical surface supporting the surface 51 of the cover member, a cylindrical web 52c forming an axially directed guide, and a web 52b disposed between the webs 52a and 52c, and having a lower conical surface supported by a spherical surface 53 of an annular elastic buffer member 54, having a centre of curvature below the mine or in a lower part thereof. The web 52c is guided on a fuse receiver member 55 which is connected to the mine casing by rivets 56. The material of the spherical surfaces 51 and 53 is harder than that of the webs 52a and 52b, so that when the cover member is subjected to heavy loading its freedom of movement is ensured. The edge 52bk of the web 52b can abut an edge 52k of the member 55, and act as a shock absorber. A fuse is retained in the member 55 by springs 60. An arming device comprises lugs 67 which project above a cover 62 and entered from a rotatable ring 66 having recesses 68 into which pins 64 can move to release a slider 63 and allow it to be moved towards the fuse by a spring 69. An opening in the bottom of the casing 1 is closed by a metal cover 57. A heat fusible screw 58 is located in the side of the casing 1, together with an auxiliary detonator 59, so that the mine can be used for demolition work.

    • A non-metallic mine pressure fuse, having a housing comprising upper and lower portions secured together, a leaf spring with its peripheral surface retained between the upper and lower housing portions and its central portion projecting upwardly in the unbiased state, a percussion pin supported for axial displacement relative to the housing and retained at a central aperture provided therefor in the leaf spring so as to penetrate a percussion explosive charge in the lower housing upon flexing of the leaf spring to a downwardly projecting position, a trip member projecting from the upper surface of the housing and arranged for axial displacement relative thereto, and a pressure translating member interposed between the trip member and the leaf spring to cause a downward flexing of the spring upon an external pressure in excess of a predetermined value applied to the trip member, wherein detent means are provided to prevent restoration of the pressure translating member to its initial position prior to the exertion of a pressure of lesser magnitude than the predetermined value.
