Abstract: A method is described for igniting discharges of inflammable fluids, such as gases which are discharged in a flare, where an ignition pellet is set in motion towards the fluid discharge along a conducting body and made to detonate in or near the fluid discharge, so that the fluid is ignited. The invention is characterised in that the device, during its travel towards the fluid discharge, goes through detonation generating events in which an electronic system registers several subsequent sequences, such as: 1) a sequence in which a control circuit (a system) is activated (switched on), 2) a sequence in which the device is activated as it passes, and registers a predetermined series of identical or different pulse influences, and 3) a sequence in which the device thereafter is made to detonate by a pulse influence which indicates that it has passed the conducting body towards the fluid discharge. A system for carrying out the method is also described.

Abstract: The present portable exterminating apparatus uses an ignite charge of gas to produce both concussion and heat within the burrow of a rodent, along with residual toxic fumes, all contributing to rodent extermination. The apparatus includes a barrel, an injection control assembly, an ignition system, and a safety system including a pressure sensor and preferably a check valve. The mixing chamber of the apparatus mixes a flammable gas, such as propane, with oxygen, preferably from a bottled oxygen source, at a desired ratio. The barrel nozzle is placed into the burrow opening, and the flammable mixture is discharged into the burrow, and subsequently ignited. The ignition system including a battery, an ignition switch, and an improved ignition component inducing arcing across a pair of electrodes located within the nozzle of the barrel. The ignition switch is preferably located near the discharge valve for one-hand operation of the apparatus.

Abstract: There are described a method, an apparatus and an ignition pellet for the ignition of combustible gases, for example from a flare or flare tower, where an ignition pellet is launched in a direction toward a region of combustible gas, characterized in that the ignition device is propelled by means of a pressure medium through a guidance tube to the gas cloud region, that the ignition device undergoes a reaction for the purpose of active ignition of the gas in the region, the time for its activation and reaction being predetermined and adapted to the particular flare and application. The reaction of the ignition device is in the form of a shower or cloud of sparks where at least parts of the shower of sparks will strike the cloud of gas.

Abstract: A torch disperses an explosive mixture of pressurized oxygen and petroleum gas into the burrow of a rodent for subsequent ignition to destroy rodents in the burrow. The torch provides a configurationally sustaining enclosed dispersement system with an elongate body formed sequentially by a mixer, a gas conduit having a valve to regulate gas passage therethrough and an output nozzle insertable into an entry orifice of a rodent burrow. An ignition system supported on the dispersement system provides an electrically powered spark plug carried in the output nozzle to ignite gases therein. The oxygen and petroleum gases are mixed in determinable proportions and pass through and from the distribution system by reason of gas pressure. The gas channel through the torch is not open to the ambient atmosphere except at the orifice of the output nozzle and a flash guard valve carried inwardly adjacent the output nozzle prevents an explosion in the output nozzle from passing inwardly into the gas conduit of the torch.

Abstract: A flame cannon for producing an explosion, the cannon including a tank, an effect valve, a nozzle and an ignitor, the tank coupled to a carbon dioxide source and a propane source, the tank and sources used to pressurize liquid propane therein. The nozzle forms a substantially linear and non-atomizing channel. When the effect valve between the tank and nozzle is opened, the pressurized liquid propane is forced through the nozzle and forms a liquid propane column thereabove which begins to disburse into the atmosphere wherein it is ignited to form a mushroom-shaped explosion.

Abstract: A transportable igniting device utilizing burn fuel especially ,adapted for use in forestry management practices is disclosed. The invention has a fuel storage tank which is fluidly coupled to a pressurizing assembly which includes; a pump and a pressure fuse which is in turn coupled to an application wand having igniting means associated therewith. The pump removes fuel from the tank and delivers it to the pressure fuse. The pressure fuse remains open during normal operation but interrupts fuel flow if line pressure varies from predetermined parameters. The fuel expelled from the application wand is ignited by the igniting means and is delivered to a distant target. Features of the invention provide for a hose to couple the pressurizing assembly to the application wand so that the wand may be distant from the assembly. In addition, a bypass valve may be located fluidly intermediate the pump and the pressure fuse to return unused fuel to the tank, thus creating a continuously cycling pressurizing assembly.

Abstract: The invention is an improved chemical firearm device that is operated and fired by an electro-mechanical system. The firearm device is of a pistol configuration, having a tank-like handle or hand-grip for containing the chemical to be discharged. A dual-action mechanical trigger mechanism is provided for first discharging the chemical through a nozzle in the barrel portion of the pistol-like device, which can be aimed like a pistol toward an assailant or target, and second to ignite the chemical during discharge if desired. An optional action is available whereby the ignition of the already discharged chemical on the assailant, or on the target, may be delayed until desired or needed in a point of close combat with the assailant or at the target. Another optional action is the availability of a high-voltage charge to stun and disable an assailant during close combat without the use of the chemical. Other uses include destruction of pest nests, and similar situations.
