  • System and method for producing and maintaining predetermined proportionate mixtures of fluids
    Patent number: 5284174
    Abstract: A system and method for producing and maintaining a predetermined proportionate mixture of two fluids, such as water and foam concentrate, in accordance with conductivity measurements of the fluids. A set point is established which is representative of the conductivity of the predetermined proportionate mixture. The conductivity of the mixture is measured and compared with the set point by conductivity probes and a microprocessor. A control valve is continuously adjusted to maintain the predetermined proportionate mixture in response to control signals from the microprocessor in accordance with the comparisons of the conductivity values.

  • Foam concentrate
    Patent number: 5225095
    Abstract: An improved foamable protein hydrolysate based concentrate is provided containing multivalent cations and a water soluble polymer, which remains stable in storage for at least six months and which, when diluted with 10 to 50 parts of water and mixed with air to generate a foam, produces a foam which lasts essentially unchanged for at least three days.

  • Method for applying a biodegradable protein foam to a substrate
    Patent number: 5133991
    Abstract: A method and apparatus for covering substrates such as landfills, sewage, contaminated soil, sludge deposits, compost piles and the like. A protein based solution, preferably mixed from a foam concentrate, is mixed with air in a foam production nozzle and then spread to an approximately uniform thickness over the surface of the substrate.In an alternative embodiment the present invention also relates to a method for providing a foam covering to substrates such as buildings and other natural and artificial structures to protect such substrates from adverse environmental conditions such as polluted air or water, insects, extreme hot and cold temperatures and toxic vapors or substances.
