Abstract : An improved technique is described for providing a mixture of a plurality of gases to be used for diving and other applications. More specifically, the technique provides for the mixture of such gases as hydrogen and oxygen while decreasing the likelihood of explosion during mixing. In particular, hydrogen and oxygen bubbles are introduced into a column of liquid through needle injectors positioned in a region of turbulent liquid flow. The liquid flow is maintained such that the bubbles from the injectors are forced through a series of baffles which gradually decrease the turbulence as the gases mix by equilibriation. When hydrogen and oxygen are mixed, the hydrogen and oxygen are maintained at a ratio of 95:5 H2-O2 such that the final concentration of gas is in the nonexplosive range. In addition, the fluid column confines any explosive mixture (produced by direct bubble contact) to the individual bubble volume enclosed by the liquid boundary. (Author)
