Patents by Inventor John Caramanian

John Caramanian has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Compositions for dynamic balancing
    Patent number: 6214906
    Abstract: Dynamic balancing compositions are described which include an epoxy resin component and a curing component. The curing component contains at least one of a polyamide agent or polyamine agent. The balancing compositions drastically reduce the time required for balancing because, immediately after their application, they can be rotated and balanced in the uncured state. The balancing compositions also have an increased pot life and can be colored with pigment to approximate the color of copper windings.
    Type: Grant

  • Concrete surface treating material and method of treating concrete surfaces
    Patent number: 4153743
    Abstract: A concrete surface is treated with a low viscosity sealant solution comprising an epoxy resin and an organic elastomeric polysulfide curing component which solution penetrates deeply into the surface and fills voids therein.

  • Method of balancing rotors and composition therefor
    Patent number: 4083735
    Abstract: In a method and composition for dynamically balancing rotors and the like, an improved epoxy resin balancing composition is applied to a rotor and the rotor is dynamically tested before the resin is cured. The resin composition includes fibrous inorganic material and a reaction polyamide hardening agent or catalyst. The composition has a specific gravity of at least 3.0.

  • Method of balancing a rotor
    Patent number: 3939020
    Abstract: A method of balancing a rotor. An epoxy resin balancing composition is applied to the rotor and the rotor is dynamically tested before the resin is cured. The resin composition includes fibrous inorganic material, which renders it cohesive, weighting material including powdered zinc and barium sulphate and a reactive polyamide, catalyst, and a diluent. The composition has a specific gravity of at least 2.0 and has substantially no slump at room temperature. The composition is sufficiently tacky, adherent, and cohesive to adhere to the rotor during dynamic testing before curing.
