Milton S. Greenhalgh 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).

  • Low temperature curing of elastomer
    Patent number: 4764549
    Abstract: A novel curable rubber composition is described which is curable at low temperatures.
    Type: Grant
    Filed: September 9, 1986
    Date of Patent: August 16, 1988
    Assignee: Vulkor, Incorporated
    Inventors: Milton S. Greenhalgh, Joseph E. Vostovich
  • Over temperature sensing system for power cables
    Patent number: 4707686
    Abstract: An over temperature sensing system is disclosed that is designed to monitor the temperature in a single or multiwire conductor. The system may be utilized in control cables or in high tension power distribution cables.
    Type: Grant
    Filed: April 3, 1986
    Date of Patent: November 17, 1987
    Assignee: General Electric Company
    Inventor: Milton S. Greenhalgh
  • Thermal-sensitive insulating composition comprising cured acrylonitrile butadiene carboxylic acid rubbers containing filler materials
    Patent number: 4666971
    Abstract: Novel acrylonitrile butadiene and carboxylated acrylonitrile butadiene elastomeric admixtures compounded with various amounts of mineral fillers such as silicates, silicas, etc., carbon blacks, and plasticizers such as esters, epoxidized polyesters, etc., are useful as continuous temperature-sensitive solids when applied to metallic conductors as coatings whereby one leg acts as a conductor and the other is used as the sensing leg. These electrical properties of these admixtures such as volume resistivity, impedance, and reactance are uniquely sensitive to temperature changes from room temperature to at least 90.degree. C. and thus offer new and important circuit design opportunities for monitoring and detecting temperature changes. These admixtures which are essentially thermosetting may be combined with other resins such as polyvinyl chloride and used thermoplastically. In these cases, the elastomer becomes the plasticizer.
    Type: Grant
    Filed: March 7, 1985
    Date of Patent: May 19, 1987
    Assignee: General Electric Company
    Inventor: Milton S. Greenhalgh
