Patents by Inventor James E. Petersen

James E. Petersen 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: 12142992
    Abstract: An electric motor is provided. The motor includes a stator and a rotor positioned concentrically within the stator. Between the ends of the rotor, the rotor lacks radial air flow paths that extend into the annular space between the rotor and the stator.
    Type: Grant
    Filed: November 17, 2020
    Date of Patent: November 12, 2024
    Assignee: Gulf Electroquip, LTD.
    Inventors: James E. Petersen, Jr., Michael David Roush, Keith Louis Verspoor, Jose Armando Godinez Rodriguez
  • Patent number: 11859641
    Abstract: An air blower is provided. The blower includes a flow modulator tube assembly positioned to modulate the flow of air into the blower and to modulate the flow of sound out of the blower. The blower also includes a sound damper. The flow modulator tube assembly directs sound to the sound damper, and the sound damper absorbs and/or reflects the sound.
    Type: Grant

  • Patent number: 6648935
    Abstract: A two stage extracting blower that cleans liquid and solid contaminants from supply air, and provides high velocity air for cooling equipment, personnel and/or structures. In a first air cleaning stage, the blower uses air velocity and the centrifugal force of a rotating impeller to separate heavier contaminants entrained in a dirty air stream into a rear partitioned chamber of the blower housing. In a second air cleaning stage, the blower uses centrifugal forces imparted by the impeller on lighter contaminants to cause the contaminants to be collected in a skimmer provided in the partially cleansed air stream prior to release of the air stream from the blower.
