Patents by Inventor Anthony G. Meszaros

Anthony G. Meszaros 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).

  • Method of heat treating metal parts using a washable synthetic quenchant
    Patent number: 4826545
    Abstract: A method of quenching metal components utilizing a water based quenching composition which includes a polyvinylpyrrolidone polymer of high molecular weight and in relatively high concentrations and thereafter power washing the parts to remove the polymeric film. Another preferred embodiment uses the same high molecular weight polyvinylpyrrolidone in combination with two rust inhibiting agents which greatly extend the time during which the quenchant film left on the quenched parts remains water soluble, while still providing an excellent approximation of the cooling curve characteristic of an oil quenchant.
    Type: Grant
    Filed: June 2, 1987
    Date of Patent: May 2, 1989
    Inventors: Robert W. Foreman, Anthony G. Meszaros
  • Method of heat treating metal using a washable synthetic quenchant
    Patent number: 4738731
    Abstract: A method of quenching metal components utilizing a water based quenching composition which includes a polyvinylpyrrolidone polymer of high molecular weight and in relatively high concentrations and thereafter power washing the parts to remove the polymeric film. Another preferred embodiment uses the same high molecular weight polyvinylpyrrolidone in combination with two rust inhibiting agents which greatly extend the time during which the quenchant film left on the quenched parts remains water soluable, while still providing an excellent approximation of the cooling curve characteristic of an oil quenchant.
    Type: Grant
    Filed: October 6, 1986
    Date of Patent: April 19, 1988
    Assignee: Park Chemical Company
    Inventors: Robert W. Foreman, Anthony G. Meszaros
  • Method for restoring molecular weight distribution of a polymeric quenchant
    Patent number: 4251292
    Abstract: The subject invention provides a method and apparatus for the control and or rectification of molecular weight distribution of polymeric quenchants. In general this is accomplished by selective filtration and elimination of lower molecular weight constituents and the resulting restoration of the molecular weight balance which is necessary to maintain the quench of the desired severity.
