  • Patent number: 4394289
    Abstract: A system for producing foam continuously. A body member defines a foam generating chamber. A foamable liquid is introduced into an inlet of the foam generating chamber. A gas is simultaneously introduced under pressure into the inlet of the foam generating chamber to form a mixture of foamable liquid and gas. The mixture is then flowed from the inlet of the foam generating chamber to an outlet thereof through a turbulator medium which substantially fills the foam generating chamber to thereby foam, mix and homogenize the mixture. The inlet and outlet of the foam generating chamber are in an imaginary substantially non-horizontal plane. The foamed and homogenized mixture is then removed from the outlet.
