    1405734 Oxygen generator LIFE SUPPORT Inc 27 Feb 1974 [6 March 1973] 8955/74 Heading C1A A chemical oxygen generator comprises a canister containing a chlorate candle 30, a sealed orifice 15 for releasing oxygen, means in the canister for activating the chlorate candle and a baffle 22 having side legs 24 embracing opposite sides of the chlorate candle and spaced in from the canister wall to provide oxygen flow paths 25 from the candle to the orifice. Activation is achieved by breaking the seal 16 with a pin and depressing a plunger in actuator cup 17 releasing water into the ignition material 42 in the recess 34 in the chlorate candle. The shape of the candle allows free oxygen flow paths, prevents overheating of the generator and provides a consistent flow rate of oxygen.

    The invention relates to the design of gas generators and can be used to produce oxygen.
    A known oxygen generator includes a cylindrical housing with a bottom and a lid in which a central opening is made, a rupture safety membrane covering the central opening, a chlorate candle with a recess in one end, an ignition device located along the axis of the housing under the central opening inside the recess, and filter elements Q.
    The disadvantage of the known generator is the insufficient efficiency of the oxygen evolution process, the difficulty of igniting the chlorate candle and the lack of purification of the oxygen produced from impurities.
    In order to intensify the process of oxygen evolution by centering the candle, simplify ignition and improve oxygen purification from
    impurities, the proposed generator is equipped with a chlorate candle installed outside the U-shaped septum with a bottom in which there is a center1, a rectangular opening, and the ignition device is made in the form of an elastic ruptured glass placed under the membrane along the axis of an elastic end
    IQ is the central opening of the U-shaped septum, a movable piston with a needle attached to it, placed in a glass, and a pressure disk separating the piston from the membrane, and
    15 filter elements are made in the form of porous disks with a central hole located between the lid, chlorate candle and the bottom, and a granulated adsorbent placed between the filtering elements above the U-shaped partition.
    In addition, the chlorate candle is made in the form of a hexagonal prism. FIG. 1 shows a generator

    25 general view; in fig. 2 - the same, in axonometric projection with a partial longitudinal section; in fig. 3 chlorate candle, general appearance; in fig. U-shaped partition, general view; in fig. 5 section A-A in FIG. 2; in fig. 6 is a section BB in FIG. five; in fig. 7 is a sectional view BB in FIG. five; in fig. 8 is a device for firing, longitudinal section; in FIG. 9 a cross-section of the FIG. eight; in fig. 10 a section DD in FIG. 9. The oxygen generator contains a cylindrical housing 1 with a bottom 2 and a cover 3 in which a central opening k is made, a rupture protective membrane 5 covering the central opening, a chlorate candle 6, in one end of which a recess 7 is made, an ignition fixture 8 located along the axes of the housing 1 under the central hole inside the recess 7, and the filtering elements 9. - In addition, the generator is equipped with an U-shaped partition 10 installed in the chlorate candle 6 with a bottom 11 in which the central the hole 12, and the ignition device 8 are made in the form of an elastic bursting cup 13 placed under the membrane 5 along the axis of the housing 1 with an elongated Tt end passing through the central hole 12 of the U-shaped septum 10 of the movable piston 15 with a needle 16 fixed on it into the cup 13, and the pressure disc 17 separating the piston 15 from the membrane 5, the filter elements 9 being made in the form of porous discs 18c with a central hole 19 located between the lid 3 of the chlorate candle 6 and the bottom 2, and the granular adsorbed This 20 placed between the filtering elements 9 above the P-about different partition 10. At the same time, chemical candle candle 6 is made in the form of a hexagonal prism. The disk 21 of ceramic-fiber material is located under the lid 3 and surrounds the upper end of the glass 13, and serves as the final anti-dust filter. A ceramic fiber gasket 22 lies under the disk 18 and also surrounds the cup 13. This disk and the gasket consist of a material that does not burn and does not emit toxic gases. Below is an adsorbent layer 20 of granulated sodium peroxide Na. Oj, activated aluminum or the like, which is an odor-absorbing layer. Under the layer 23, there are two superimposed filters 2, which have holes 19 and are filled with an initial inflammable material 25, such as an iodate flammable composition. Two layers 23 can be combined into one thick pad. The chlorate candle 6 is sandwiched in the partition 10 between the 2k filters and the bottom 11. The candle is a compressed briquette consisting mainly of alkali metal chlorate, preferably sodium chlorate, and a sufficient amount of sodium or potassium oxide catalyst to support the catalytic decomposition reaction, in which oxygen will be released from chlorate without any additional heat or additional fuel. To obtain oxygen, they press on the pressure disk 17, which breaks through the membrane 5 and presses on the piston 15. The piston 15 moves Il-16, which pierces the end 1A of the cup 13. Water filling the cup 13 is injected into the first flammable material 25. With With this material, the ignition of the whole candle 6, which gives off oxygen during combustion. The flow of oxygen will be mainly directed downwards to the body of the candle 6 through the channels 26. The flow allows preheating of the candle bottom: at low temperatures. Further, oxygen enters the purification by filtering through a ceramic fiber disk 21, the adsorbent 20 and disk 18, and exits through the hole k in the cap 3. The oxygen path thus passes between the candle and the side wall of the case, where heat can be dissipated from oxygen, so that oxygen is liberated at room temperature. Formula 1-. An oxygen generator, including a cylindrical housing with a bottom and a lid in which a central opening is made, a rupture safety membrane covering the central opening, a chlorate candle with a recess in one end, an ignition device located along the axis of the housing under the central opening inside the recess, and filtering elements, characterized in that, in order to intensify the process of oxygen evolution due to the centering of the spark plug, simplify ignition and improve oxygen purification from impurities, it is equipped with a chlorate candle installed outside the U-shaped septum with a bottom in which a central hole is made, and with the ignition method made in the form of an elastic ruptured glass with an elongated end under the diaphragm along the body axis, 329696
    walking through the central opening of the U-formed partition, the movable piston with a needle attached to it,
    placed in a glass, and a pressure disk 5 separating the piston from the membrane, the filtering elements being made in the form of porous disks with a central hole located between the lid, chlorate candle 10 and the bottom, and a granular adsorbent placed between the filtering elements above the U-shaped septum.
