  • Patent number: 4653591
    Abstract: A foam generation device and method of producing foam wherein an electrical charge is placed upon a foam producing solution or admixture thereof with air. The above admixture is then forced by air pressure through a grounded foam-producing mesh such that foam bubbles are produced at high efficiency. In addition, the turbulence of the air passing through the device may be reduced by a honeycomb section. This honeycomb section in turn may be grounded and the air flow through the device reversed such that already produced foam may be drawn into the device, charged by the grid, and thereafter dissipated upon the honeycomb section.
