A tool for manipulating a tubular. The tool comprising a plurality of tool sections arranged in a stack, each tool section comprising a propellant source having an upper surface and lower surface, the upper and lower surfaces being separated by an outer surface extending around the perimeter of the propellant source, a first flame retardant material being associated with the propellant source upper surface and a second flame retardant material being associated with the propellant source lower surface. The tool further comprises at least one modifying agent provided in or adjacent the tool sections or generated by the tool sections; and an ignition mechanism for igniting the propellant source outer surface of each tool section, such that upon ignition, each propellant source is adapted to deflagrate, creating a stream of combustion products, the stream of combustion products extending around, and flowing away from, the outer surface of said propellant source.

The present invention relates to a firearm projectile capable of releasing a secondary payload mid-flight through a pyrotechnic timing mechanism. Once the firearm is fired, the powder in the casing pushes out the projectile as a typical round. In addition, the powder ignites the delay column. The formulation and amount of delay pyrotechnics determines the delay time. When the delay column is burned, the final portion ignites an expelling charge. The expelling charge builds pressure in the projectile casing and separates the base plug from the main projectile housing. The expelling assembly pushes out the secondary payload out the rear of the projectile. Although the payload exits the rear of the projectile at minimum velocity, the net velocity of the payload is still in the forward direction.

The present disclosure relates to a pyrotechnic object, in particular an irritation body, irritation projectile or ammunition, comprising an ignition device, comprising a delay chamber extending along a delay path, in which chamber a delay charge is accommodated, and comprising at least one and preferably a plurality of effect chambers in which or in each of which an effect charge to be ignited is accommodated, wherein the delay chamber is transversely connected to a respective effect chamber via a respective over-ignition opening which branches off from the delay chamber and forms an over-ignition path, wherein in the case of a plurality of effect chambers the plurality of over-ignition openings are arranged successively downstream along the delay path in the order of the effect charges to be ignited.

An energetic material having thin, alternating layers of metal oxide and reducing metal is provided. The energetic material may be provided in the form of a sheet, foil, cylinder, or other convenient structure. A method of making the energetic material resists the formation of oxide on the surface of the reducing metal, allowing the use of multiple thin layers of metal oxide and reducing metal for maximum contact between the reactants, without significant lost volume due to oxide formation. An ignition system for the energetic material includes multiple ignition points, as well as a means for controlling the timing and sequence of activation of the individual ignition points. A gas producing layer is also provided to increase pressure.
