Drop Grenade Patents (Class 89/1.52)
  • Patent number: 8935975
    Abstract: An incendiary machine (10) comprises a feed and dispensing system (12), a priming system (20) and a control system. The feed and dispensing system (12) feeds a belt (14) of incendiary capsules (16) to a region at which individual capsules are separated from the belt and dispensed from the machine (10). The priming system (20) primes the capsule (16) prior to being dispensed from the machine (10) with a priming liquid which, when delivered into a capsule, facilitates an exothermic reaction. The control system controls the feed and dispensing system (12), and the priming system (20) independently of each other so that the belt (14) can be fed into and indeed thought the machine (10) with the priming liquid being injected into the capsules.

  • Patent number: 8490924
    Abstract: A method for launching counter-measures from a launch opening of a dispenser mounted on an aeroplane. The counter-measures are launched in a direction obliquely forwards and downwards relative to the aeroplane. In order to facilitate launching of counter-measures, a low dynamic pressure is created permanently across the launch opening of the dispenser by a fixed element acting on the air stream. An arrangement for storing and launching counter-measures including an elongate body provided with at least one launch opening used for storing the counter-measures in compartments. The arrangement is designed to be mounted on an aeroplane with the longitudinal direction of the elongate body essentially coinciding with the flight direction of the aeroplane. The counter-measures are connected to a firing control unit for feeding firing signals to the counter-measures. The arrangement is designed to be mounted under the aeroplane.

  • Patent number: 7451679
    Abstract: An apparatus (10) for initiating and dispensing an incendiary comprises a feed mechanism (12) for advancing a line of series connected incendiaries to a dispensing location D; an injection device (14); and a cutter (16). The injection device (14) injects a substance such as glycol into the incendiary as it is moved toward, but prior to reaching, the dispensing location D. The glycol reacts exothermically with another substance such as potassium permanganate in the incendiary. The cutter (16) cuts the incendiary into which the glycol has been injected from the line of series connected incendiary. After the incendiary has been injected with the glycol and cut by the cutter (16) from the line, the feed mechanism (12) advances the incendiary to the dispensing location D where it is dispensed by the action of gravity from the apparatus (10).
