  • Patent number: 4889654
    Abstract: An aqueous solution, preferably an aqueous disinfectant solution, containing chlorine dioxide and which is capable of forming a foam, and methods for the preparation and use thereof. An aqueous disinfectant solution capable of forming a foam is prepared by adding a foaming agent, i.e., a suitable surfactant, to water. Chlorine dioxide may then be added to the solution or it may be generated in situ by reacting an oxidizing agent, a cationic exchange resin in the acidic form, or an acid with a metal chlorite dissolved therein. The resultant foam solution may subsequently be foamed by being mixed with air in a foam generator. The foam solutions of the instant invention are useful as cleaning and/or sanitizing agents.
    Type: Grant

  • Patent number: 4538545
    Abstract: A foam generating and distributing manifold device for generating and transporting foam cleansing and sanitizing agents having a manifold chamber with a centrally disposing frothing tube to generate foam which migrates upwardly within the chamber to a plurality of annularly disposed egress ports through which foam is distributed to a series of substantially equidistant supply conduits thereafter migrating to a distribution manifold which distributes the foam evenly upon, for example, conveyor belts used in food processing or the like.
