  • Publication number: 20180214723
    Abstract: An incendiary capsule 10 has a body 14 forming a single compartment containing a first part 18 of a two part ignition system and a quantity of a pyrotechnic heat source (PHS) 16. The capsule 10 is initiated by injecting, when ready for use, a quantity of a second part of the two part ignition system. The ignition system generates sufficient heat to initiate the PHS 16, which burns at a substantially higher temperature than the ignition system.

  • Publication number: 20180215679
    Abstract: An ignition formulation for an incendiary material is disclosed. The ignition formulation comprises an initiator capable of reacting exothermically with the incendiary material to an extent sufficient to generate a flame when contacted with the incendiary material and a non-aqueous inhibitor capable of slowing the rate of exothermic reaction between the incendiary material and the initiator, thereby providing a delay period between contact of the ignition formulation with the incendiary material and generation of the flame. The non-aqueous inhibitor may be a compound selected from a group comprising, for example, long chain (C5-C12) alcohols, alkanes, alkenes, cycloalkanes, ethers, esters, ketones, carboxylic acids, aromatic hydrocarbons, organonitrates, diesel, biodiesel, kerosene, modified kerosene and oils.

  • Patent number: 9550569
    Abstract: A frame has a first frame portion configured to sit on a base of a vehicle seat and demountably receive a machine. A second portion of frame is coupled with and extends substantially upright from the first portion. The second portion is adjacent and bears against a back of the seat. Extending across the second portion from side to side is a lateral frame element. The lateral frame element enables the frame to be secured on and to the seat by way of a conventional seat belt. The frame also includes a pivoting support shown in this embodiment as a tray for supporting a box of capsules which are dispensed by the machine.

  • 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: 6877433
    Abstract: An incendiary 10 includes a plurality of containers 12 each containing a volume of a first substance such as potassium permanganate which, when mixed with a second substance such as glycol which is injected at a later time, reacts exothermically to generate a flame. Frangible couplings in the form of tabs 16 couple or connect adjacent containers 12 together. Thus the incendiary 10 is in the form of a flexible belt having a plurality of containers 12 which are mutually held together until separated by a dispensing/initiating machine. Each container 12 includes a flat surface 22 and a receptacle 18 having an opening 20 which opens onto the flat surface 22. A seal 24 extends across and closes the opening 20.

  • Patent number: 4032722
    Abstract: Apparatus including a telephone instrument for connection to a public telephone system has provision for a call connection to be set up through the system to just a single party upon operation of a single push-button. A plurality of electric switches are preset (usually prior to installation of the instrument) to characterize the directory number of the party that can be called. Upon operation of the push-button, electronic circuitry scans the switches characterizing the directory number to cause the decimal digits of that number to be written sequentially into storage circuitry which subsequently generates a train of impulses in respect of each such digit for transmission to line. There is provision for the scanning operation to be halted for a predetermined period after some of the digits have been written into the storage circuitry.

  • Patent number: 3956596
    Abstract: A pushbutton telephone semiconductor dialling circuit power supply comprising a capacitor fed by a diode bridge placed in series with the line looping circuit during dialling. The capacitor size is chosen to charge to at least minimum circuit supply voltage during make periods of line looping, and to keep the circuit supplied during break periods. A constant current charging circuit may be employed to charge the capacitor from the bridge to improve performance, with a diode to power the circuit directly from the bridge while the capacitor is still charging.The microphone-bridging off-normal contacts may be replaced by a transistor switching circuit.

  • Patent number: 3943300
    Abstract: A repertory dialler has a main digital data store for the storage of information required for impulsing to line upon operation of a selected call push-button. This store is a circulating dynamic store. The dialler may be operated either in a recording mode or in an impulsing mode as determined by the position of a manually-operable switch.In the recording mode, the identity of a call push-button that has been operated is first written in digital form into a circulating buffer store. This is followed by the decimal digits of the exchange and/or directory number of a subscriber which are entered by means of a digit keypad. When all the required digits have been so stored, the data temporarily stored by the buffer store is transferred to the main store and in the main store is added to the end of the block of data circulating therein.
