  • Patent number: 9746292
    Abstract: Container (10) is generally cylindrical except for a longitudinal concave groove (11) extending along its entire length. Upon explosion, the contour of this groove (11) results in a focussing effect on the wall material due to the oblique angle at which the expanding cylindrical detonation wave front impacts upon its inner wall. This produces the forging of a rough rod-like projectile (111) which, being coherent, maintains its velocity and consequently travels much further than the randomly shaped projectiles (101).
    Type: Grant
    Filed: July 14, 2014
    Date of Patent: August 29, 2017
    Assignee: ALFORD RESEARCH LIMITED
    Inventors: Roland Alford, Sidney Alford
  • Patent number: 9322624
    Abstract: A liquid-jacketed disrupter comprising a container (101) for receiving liquid and housing a receptacle (120) for explosive material, in which the container comprises one or more indentations (115) which result in the generation of liquid jets upon detonation.

  • Patent number: 5341742
    Abstract: A firing arrangement for initiating a secondary explosive includes a switch, a charge storage circuit for storing an electrical charge, a power supply for charging the charge storage circuit, an initiator electrically connected to the charge storage circuit through the switch, for directly initiating the secondary explosive, and a common unit. The common unit is hand held during initiation and houses the initiator and at least one of the switch, the charge storage circuit, and the power supply. The common unit includes a manual activator for causing discharge of the charge storage circuit through the switch and initiator, to directly initiate the secondary explosive.
