  • Patent number: 5279761
    Abstract: An oxygen-generating candle composition is disclosed of the type that includes an amount of an alkali metal chlorate or perchlorate oxygen source and which upon initiation and decomposition yields oxygen and residual chlorine, wherein the improvement comprises a non-toxic additive in the candle composition for suppression of the residual chlorine and to enhance uniform oxygen generation and evolution. The additive comprises from about 0.1% to about 1.0% by weight of lithium peroxide. The composition also includes a cobalt oxide catalyst, an iron powder fuel and a binder or filler.

  • Patent number: 5198147
    Abstract: An improved chemical oxygen generator (10) includes an oxygen generating candle (12) having an oxygen source, which upon decomposition will yield oxygen, and a nontoxic additive to smooth decomposition and suppress formation of toxic free chlorine gas. The nontoxic additive may be taken from the group consisting of: (1) the oxides, hydroxides and carbonates of calcium and the rare earth elements; (2) the hydroxides and carbonates of magnesium; and (3) mixtures of the foregoing. A complete chemical oxygen generator utilizes the candle (12) of the invention. The oxygen generator preferably includes a canister (14), oxygen-generating candle (12), and an ignition device (16). Triggering of the ignition device ignites an ignition pellet (52) which initiates decomposition of the candle body (50). Once initiated, the candle will sustain decomposition to release breathable oxygen until the candle is completely reacted.
