  • Patent number: 5078911
    Abstract: An apparatus for making a post-foaming gel comprising, a first cylinder having a chamber and a slidable piston separating the chamber into a first compartment to receive a gel base and a second compartment, a second cylinder having a chamber and a slidable piston separating the chamber into a first compartment to receive the gel base and a second compartment, a conduit connecting the first compartments of the first and second cylinders, a device for reciprocating the pistons in the first and second cylinders to cycle the gel base through the conduit between the first compartments of the first and second cylinders, and a device for introducing a foaming agent to the gel base while it is being cycled between the cylinders.

  • Patent number: 4980085
    Abstract: An apparatus for making post-foaming gels comprising, a piston chamber having an outer case defining a chamber, a piston being slidably received in the case and separating the chamber into a first compartment adjacent one end of the case for retaining a gel base, and a second compartment adjacent the other end of the case for retaining a compressed gas, with said piston having a hollow stem extending out of the other end of the case. The apparatus has a device for circulating the gel base through the stem and first compartment, and a device for introducing a foaming agent to the gel base while it is being circulated through the piston chamber.

  • Patent number: 4915881
    Abstract: An apparatus for making a post-forming gel comprising, a first cylinder having a chamber and a slidable piston separating the chamber into a first compartment to receive a gel base and a second compartment, and a second cylinder having a chamber and a slidable piston separating the chamber into a first compartment to receive the gel base and a second compartment, with the first compartments of the first and second cylinder facing each other. The apparatus has a shaft connecting the pistons of the first and second cylinders, and a conduit connecting the first compartments of the first and second cylinders. The apparatus has a device for reciprocating the pistons in the first and second cylinders to cycle the gel base through the conduit between the first compartments of the first and second cylinders, and a device for introducing a foaming agent to the gel base while it is being cycled between the cylinders.

  • Patent number: 4486329
    Abstract: A clear, single phase, liquid cleaning composition particularly suitable for cleaning hard surfaces which leaves a low residue on unrinsed, cleaned surfaces consisting essentially of, by weight, 2-8% of an amine salt of an anionic sulfated or sulfonated detergent containing an alkyl radical of 8 to 22 carbon atoms in the molecule, 1-4% of water-soluble, ethyleneoxylated nonionic detergent, 2-15% of an amine salt of C.sub.1 -C.sub.3 monocarboxylic acid builder, 0.1%-4% of amine, 0-2% of an amine salt of a C.sub.8 -C.sub.18 carboxylic acid, 0-8% of urea and water, the weight ratio of builder to total detergent being in the range of 1:6 to 5:1 and said amine being selected from the group consisting of mono-, di- and tri-ethanol amine and etheylene diamine. Preferred compositions contain either the diethanolamine salts or the 2-aminoethylammonium salts.
