  • System, methods, and compositions for detecting and inhibiting leaks in transmission systems
    Patent number: 7673497
    Abstract: System, methods, and compositions are described for detecting and inhibiting leaks of a transmission system. The composition may include one or more transmission system sealants and one or more light activated compounds. The transmission system sealant(s) inhibit one or more of the leaks in the transmission system. One or more of the light activated compounds are visible when activating light is directed towards a portion of the exterior of the transmission system.

  • Rust converting and removing compositions
    Patent number: 4824589
    Abstract: A rust converting composition comprises ascorbic acid, lignin sulfonate, and a water insoluble polymer, such as polyvinylpyrrolidone, and optionally a thickener. The invention further provides a method for removing rust from rusted metal surfaces by applying the composition, allowing the composition to remain on the rusted metal surface until substantially all of the rust is converted to a water soluble form, and removing the composition from the metal surface by washing with water.

  • Rust conversion coatings
    Patent number: 4609406
    Abstract: A rust conversion composition comprises the reaction product of a polyhydroxybenzoic acid and a alkane polyol, in admixture with a film forming polymer, and water. The composition is applied to rusted, iron-containing surface, and allowed to dry to form a hard, moisture and corrosion resistant film. Alternatively, the film may be removed to produce an iron-containing surface free of rust.
