Filed:

Aug 29, 2000

Appl. No.:

09/649778

Inventors:

Michael Brunn - Plainview NY 11802
Jacob Kravel - Plainview NY 11802

International Classification:

F42B 1246

US Classification:

102368, 102482

Abstract:

A tear gas grenade having a pressurized CO 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 CO 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 CO 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 CO 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.

International Classification:

F42B 1234

US Classification:

102502, 102444

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.

Filed:

Jun 29, 2007

Appl. No.:

11/770914

Inventors:

Jacob Kravel - Plainview NY, US
Michael Brunn - Plainview NY, US

International Classification:

F42B 4/26

US Classification:

102336

Abstract:

A flare apparatus constructed of a flare case with a primer functionally coupled to a propellant charge. Loaded within the flare case is a flare cup, having within, a starter composition, a flare composition, and a flash charge. The flare composition is functionally coupled to the flare starter composition, and the flash charge is functionally coupled to the flare composition. Upon primer activation the propellant charge is ignited. Flame and hot gasses from the propellant charge propel the flare cup out of the flare case and downrange while also igniting the flare starter composition within the flare cup. The flare starter composition ignites the flare composition, which produces a visual artifact and subsequently ignites the flash charge which produces a visual and audible artifact at or near the end of its flight.

Appl. No.:

Inventors:

Jacob Kravel - Great Neck NY, US

Assignee:

Combined Systems, Inc. - Jamestown PA

International Classification:

F42B 27/00
F42B 33/04

US Classification:

102487, 1563031

Abstract:

A grenade is defined by a body made from a rubberized material, the body including a hollow interior and a stem section. A cap is releasably secured to the stem section, the cap retaining a fuze assembly which is threadingly engaged therewith. The grenade is equipped with an ejection charge that causes said cap and said fuze assembly to be separated from said body prior to detonation of the grenade. A hydrophobic sealing layer applied to the exterior of the stem section and cap provides a watertight seal relative to the interior of the grenade, but without substantially interfering with the ejection of said cap and fuze assembly.
