A method of and apparatus for separating a lighter gas from a heavier gas in a gas mixture. The method involves directing generally annular jets of a jet gas into the gas mixture, and extracting the lighter gas from the gas mixture through central zones of the generally annular jets. The apparatus comprises a jet membrane separating a chamber for the gas mixture and a chamber for the gas enriched in the lighter gas, the jet membrane utilizing annular jet orifices communicating with the gas-mixture chamber and utilizing extraction tubes at the jet orifices and interconnecting the two chambers. A jet gas delivered to the jet orifices is discharged therethrough into the gas-mixture chamber, and the lighter gas of the mixture passes through the extraction tubes into the chamber for the gas enriched in the lighter gas. By cascading a number of jet membrane stages of the foregoing nature, a very high degree of purity for the lighter gas may be achieved.

Jet membrane gas separator and method

An apparatus for collecting solar energy wherein a heat exchange array of plastic or the like is protected against damage by excessive heat buildup. The array is housed in a normally closed chamber having a portion transparent to solar rays and the chamber is periodically vented by means responsive to heat expansion of the enclosed array. The invention permits substantial cost reductions in solar heat exchanges; particularly of the type adapted to heat buildings, swimming pools and domestic water systems.

Solar heater with automatic venting

A spark gap switch having a central electrode positioned within an annular electrode in a dielectric liquid or saturated vapor flow line, with coaxial or parallel plate electrical connections to said electrodes.
