The invention discloses a unidirectional spray type fire extinguishing bomb without high explosive fragmentation, includes a housing, a fuse, an igniter, an fire extinguishing agent and a main charge, and further includes a tail braking device, combustor, a plate closure, a piston and a diffuser. The housing, the tail braking device and the piston are made of light metal materials; the housing is cylindrical; the tail braking device is arranged at the bottom of the housing and is fixed with the housing through a screw nail; and the fuse is arranged on the diffuser and is fixed through a screw nail. During working process, when the fuse detects the fire extinguishing bomb to be 5-10 meters far away from a combustion source, the igniter ignites the main charge, the piston is pushed under high pressure to move in the housing, and the fire extinguishing agent is sprayed out from spraying holes to the combustion source for fire extinguishing. The present invention has simple structure, and has no lethality when the fire extinguishing agent is sprayed.

A scent emitting dart for dispersing an olfactant in the target area without having to physically enter the target area includes an elongated, textured shaft member that has a proximal end and a distal end, a tip member which includes a weighted portion and a tip portion integral with the distal end, and a scent carrying fletching integral having a plurality of absorbent vanes adjacent to the proximal end. The absorbent vanes both extend outwardly from the circumference of the shaft member to provide aerodynamic stabilization and also extend behind the shaft member to both increase the olfactant absorption capacity of the fletching and provide an accessible point of concentration for applied olfactant. In this regard, as the olfactant is emitted from the fletching, a hunted animal can be drawn thereto.

A distance combat means for non-lethal exposure of the human or animal body to an irritant is provided. The distance combat means comprises a housing (2,4) containing at least an irritant (5), a propellant (3), and moreover at least a medical adhesive (7), namely a cyanoacrylate preparation, polyvinylpyrrolidone or cellulose nitrate. The irritant may be 2-chlorobenzylidene malonic acid dinitrile (CS), ω-chloroacetophenone (CN) or capsaicin (CPS).

An ordnance for air-borne delivery to a target under remotely controlled in-flight navigation. In one embodiment, self-powered aerial ordnance includes upper and lower cases. A plurality of co-axial, deployable blades is powered by a motor positioned in the upper case. When deployed, the blades are rotatable about the upper case to impart thrust and bring the vehicle to a first altitude above a target position. An explosive material and a camera are positioned in a lower case which is attached to the upper case. The camera generates a view along the ground plane and above the target when the ordinance is in flight. When the vehicle is deployed it is remotely controllable to deliver the vehicle to the target to detonate the explosive at the target. The ordnance may drop directly on a target as a bomb does.

Disclosed is a fire-fighting device, which includes a casing that delimits an inner cavity in which at least one dispersible fire-extinguishing agent is deposited, and pyrotechnics suitable for generating an explosion causing the casing to rupture and the fire-extinguishing agent to be dispersed. The pyrotechnics include at least one explosive charge, generating the explosion, and a detonator for triggering the explosion of the at least one explosive charge. The detonator includes an ignition device designed to trigger, when in an active state, the explosion of the at least one explosive charge, and an impact sensor designed to detect a mechanical impact received by the device and to bring the ignition device to the active state upon detection of the mechanical impact.

The present compact powder fire-extinguishing device comprises a container containing a fire-extinguishing powder, said container being in the form of a single-use cartridge (1) containing a fire-extinguishing powder (3), said cartridge being separable from the fire-fighting device by means of a reusable fast-action firing device (4), wherein the fire-extinguishing powder (3) is disposed inside of a casing (2) of the cartridge (1) in a polymer tube (5), one end (6) of which is fastened at an outlet of the casing (2) of the cartridge (1), about the periphery of said casing, and the second end of the tube (5) abuts a sleeve (7) and is configured as a piston (8) having an aperture (9). Within the casing (2) of the cartridge (1) are provided means that generate a propulsive charge and are configured as a striker-type igniter-percussion cap (15) and a pyrotechnic gas generator (16) disposed one after the other, said gas generator being connected to the cavity of the sleeve (7), and the other end of the cartridge (1) is provided with a contoured surface (18) and is connected to the firing device (4) that comprises a mechanism for fastening and discharging the cartridge. Furthermore, the firing device (4) is provided with a striker trigger mechanism that comprises a head (30), a flat striking spring (32) having a striker (33), a hammer (38) connected to a trigger (41), and a safety catch (46).

Devices and methods for pest control, including devices useful to place pest control devices at locations of use such as at a crop (e.g., at a branch of a tree), certain embodiments of devices including a capsule and a tether that can become tangled or caught in a tree or other crop location.
