  • Method of preparing a low lethality round
    Publication number: 20030116051
    Abstract: An anti-personnel projectile launched from a weapon shell required at impact to have a low lethality consequence, in which the projectile is fitted in the shell in a shape characterized by a blunt end in the direction of flight and maintained in this shape by oppositely directed air resistance and propelling forces to obviate a change of shape during flight that might cause a serious injury.
    Type: Application
    Filed: November 21, 2002
    Publication date: June 26, 2003
    Inventors: Jacob Kravel, Michael Brunn
  • Method of preparing a low lethality projectile for flight in 37mm and 40mm weapon shells
    Patent number: 6374742
    Abstract: An anti-personnel projectile launched from a 37 mm or 40 mm weapon shell required at impact to have a low lethality consequence, in which the projectile is fitted in the shell in a shape characterized by a blunt end in the direction of flight and maintained in this shape by oppositely directed air resistance and propelling forces to obviate a change of shape during flight that might cause a serious injury.
    Type: Grant

    Inventors: Michael Brunn, Jacob Kravel
  • Launchable flameless expulsion grenade
    Patent number: 6349650
    Abstract: A tear gas grenade having a pressurized CO2 container oriented with a top in the trajectory direction to a target area and in facing relation to a top-piercing component across a clearance of a tracking compartment therebetween, in the operation of which a fuel-produced gas expands to simultaneously urge the top-piercing component in descending movement puncturing the CO2 container and also sealing the tracking compartment against venting of the fuel-produced gas and, after a time interval of contraction of the fuel-produced gas, the CO2 pressure urges the top piercing component in ascending movement unblocking the puncture opening in a container top and also unsealing the tracking compartment, to thereby correlate the expulsive effect of the CO2 to the time interval of the sealed contraction of the fuel-produced gas contributing to a tear gas consequence adjacent or in the target area.

  • Method of preparing a low lethality projectile for flight
    Patent number: 6202562
    Abstract: An anti-personnel projectile launched from a 12 gauge shotgun shell required at impact to have a low lethality consequence, in which the projectile is fitted in the shell in a shape characterized by a blunt end in the direction of flight and maintained in this shape by oppositely directed air resistance and propelling forces to obviate a change of shape during flight that might cause a serious injury.
