1. A tear gas enhanced fluid bed security system comprising:
- a fluid bed having an enclosure within which a plurality of fluidizable granular solids is disposed;
a gas fluidizer;
a plurality of lines, said lines supplying fluidizing air from said gas fluidizer to said plurality of fluidizable granular solids; and
a first tank comprising a tear gas solution comprised of 2-chlorobenzalmalononitride (CS) and a methylene chloride solvent, said tank being fluidly connected to said plurality of lines supplying fluidizing air;
wherein when said gas fluidizer is activated, said air and said tear gas solution is supplied together to said plurality of lines to disperse said tear gas solution through said fluid bed.

Abstract
A tear gas-based enhancement to a fluid bed security system implemented for the purpose of inhibiting unauthorized entry or access and to provide additional time for threatened individuals to evacuate or escape a hostile assembly at the perimeter of a secured area. The system provides for the reliable and controlled application of a specified concentration of tear gas emitted in conjunction with fluidizing gas distributed through a fluid bed configuration comprising a gas distribution piping array and a plurality of fluidizable granular solids in a surrounding relationship to the gas distribution piping array.

17. A tear gas delivery system for supplying a reliably controlled concentration of tear gas, comprising:
-
an air blower; a supply line having a gas distribution array, said supply line being attached to said air blower; a surge tank fluidly connected to said air blower and said supply line; a first tank, said first tank holding tear gas solution comprised of a mix of 2-chlorobenzalmalononitride (CS) and a methylene chloride solvent, said tank being fluidly connected to said supply line; a second tank, said second tank holding nitrogen and being fluidly connected to supply nitrogen to said first tank holding said tear gas solution wherein when said air blower is activated, said tear gas solution is released into said supply line for mixing with air and said tear gas solution is supplied via said gas distribution array for dispersion of said tear gas solution. - View Dependent Claims (18)

19. A method of reliably delivering a controlled concentration of tear gas to deal with hostile assemblies in a non-lethal manner, comprising the steps of:
-
providing a fluid bed enclosure having an open perimeter; providing a plurality of fluidizable granular solids disposed in said fluid bed enclosure; providing a gas distribution array leading to said first enclosure; providing a gas fluidizer and connecting said gas fluidizer via a line to said gas distribution array; providing a first container with tear gas solution fluidly connected via said line to said gas distribution array; fluidizing the fluid bed enclosure by activating said gas fluidizer; and releasing said tear gas solution in said line for delivery to said fluid bed enclosure in a concentration that is below a lethal level; wherein when said fluid bed enclosure is fluidized, said tear gas solution enters said line and is dispersed through and above said fluidizable granular solids when said fluidizable granular solids are fluidized. - View Dependent Claims (20)
