Patents by Inventor Sami B. Awad

Sami B. Awad 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).

  • Patent number: 5464477
    Abstract: The present invention relates to an aqueous composition and process useful for cleaning and drying ferrous surfaces. According to the invention, a water-immiscible hydrocarbon or non-halogenated organic solvent cleaning step is followed by an aqueous displacement solution (ADS) which contains a surfactant component and a pH modifier component in sufficient amounts to substantially displace the hydrophobic organic solvent residue from the surface of the substrate and prevent its redeposition. The ferrous metal surfaces are then rinsed with hot deionized ultrasonically agitated water which comprises one or more water soluble basic components. This aqueous composition is capable of protecting ferrous metal surfaces form flash rusting after aqueous cleaning or solvent treatments of the surfaces, and particularly during the deionized water rinsing and drying steps.

  • Patent number: 5397397
    Abstract: The present invention relates to an aqueous composition and improved process useful for cleaning and facilitate drying of various metallic and non-metallic surfaces or components. According to the invention the water-immiscible hydrocarbon or non-halogenated organic solvent cleaning step is followed by an aqueous displacement solution (ADS) which contains a surfactant component and a pH modifier component in sufficient amounts to substantially displace the hydrophobic organic solvent residue from on the surface of the substrate and prevent its redeposition. The improved process is an alternative for replacing the ozone depleting chlorofluorocarbons and Halogenated solvents (ODS) or other volatile organic solvents (VOC) being commonly used in cleaning variety of industrially manufactured metallic and non-metallic components.

  • Patent number: 5389199
    Abstract: A lubricant and surface conditioner for formed metal surfaces, particularly beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. The conditioner includes a water-soluble organic material selected from a phosphate ester, alcohol, fatty acid including mono-, di-, tri-, and polyacids; fatty acid derivatives such as salts, hydroxy acids, amides, esters, ethers and derivatives thereof; and mixtures thereof.

  • Patent number: 5064500
    Abstract: Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) alkoxylated phosphate esters, (ii) ions of aluminum, zirconium, iron, tin, and/or cerium, (iii) a metal etching component, and (iv) a combination of alkoxylated alcohol and alkoxylated alkyl phenol emulsifiers, gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses. The cans after treatment are substantially free from any water breaks when rinsed with water.

  • Patent number: 4944889
    Abstract: The process of reducing the coefficient of static friction on the outside surface of a metal can by applying thereto a lubricant and surface conditioner for formed metal surfaces, particularly beverage containers, which reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature.The conditioner is a water-soluble organic material selected from a phosphate ester, alcohol, fatty acid including mono-, di-, tri-, and poly-acids; fatty acid derivatives such as salts, hydroxy acids, amides, esters, ethers and derivatives thereof; and mixtures thereof.

  • Patent number: 4859351
    Abstract: A lubricant and surface conditioner for formed metal surfaces, particularly beverage containers, which reduces the coefficient of static friction of said metal surfaces and increases their mobility without adversely affecting the adhesion of paints or lacquers applied thereto. The conditioner is a water-soluble organic material selected from a phosphate ester, alcohol, fatty acid including mono-, di-, tri-, and poly-acids; fatty acid derivatives such as salts, hydroxy acids, amides, esters, ethers and derivatives thereof; and mixture thereof.
