Patents by Inventor Martin J. Mastroianni

Martin J. Mastroianni 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).

  • Apparatus with dielectric gas mixtures in substantially uniform field
    Patent number: 4204084
    Abstract: Dielectric gas mixtures are described with improved dielectric strength in uniform fields compared to pure sulfur hexafluoride. Sulfur hexafluoride is mixed with about 1 to about 10 mole % of a noble gas such as helium, argon, krypton or neon and used in a device wherein the dielectric gas is subjected to a substantially uniform field such as compressed gas insulated cable.
    Type: Grant
    Filed: June 26, 1978
    Date of Patent: May 20, 1980
    Assignee: Allied Chemical Corporation
    Inventors: Martin J. Mastroianni, Sabatino R. Orfeo
  • Electrical device with fluorinated divalent sulfur dielectric gas
    Patent number: 4166798
    Abstract: Electronegative, normally gaseous, fluorinated compounds with sulfur at valence state 2 act as good dielectric gases alone or in combination with sulfur hexafluoride. In particular bis (trifluoromethyl) sulfide has a higher dielectric strength than sulfur hexafluoride when used alone and increases dielectric strength of sulfur hexafluoride in blends.
