Patents by Inventor J. William Putt

J. William Putt 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).

  • Magnetic apparatus for producing movement
    Patent number: 4396874
    Abstract: Apparatus for providing movement includes an electromagnet. The time required to attain a given value of current flow in a magnet coil is shortened by initially providing a higher voltage to attain quickly the desired current flow, and then providing a lower voltage.
    Type: Grant
    Filed: January 28, 1982
    Date of Patent: August 2, 1983
    Inventor: J. William Putt
  • Magnetic apparatus for producing movement
    Patent number: 4340846
    Abstract: A driven paramagnetic member, located between two stationary magnetic members, is moved in opposite directions by alternately energizing intermediate magnets which are located between the stationary members and the driven member. To conserve electrical energy, the ampere-turns of the intermediate magnets are reduced gradually while the members are moving together to reduce the gap thicknesses therebetween.
    Type: Grant
    Filed: December 18, 1980
    Date of Patent: July 20, 1982
    Inventor: J. William Putt
  • Magnetic apparatus for producing movement
    Patent number: 4249115
    Abstract: A driven body is moved in opposite directions by alternately magnetizing two sets of paramagnetic bodies, each set being located between a drive magnet longitudinally affixed to the driven body and a stationary magnet toward which the magnetized bodies are attracted.
    Type: Grant
    Filed: October 16, 1978
    Date of Patent: February 3, 1981
    Inventor: J. William Putt
  • Magnetic apparatus for producing movement
    Patent number: 4121139
    Abstract: A plurality of aligned magnets are movable with respect to each other and their polarities are changed to cause changing of the distances between adjacent magnets by opening and closing of air gaps therebetween. Driven magnets travel a distance which is greater than the air gap between any two adjacent magnets.
    Type: Grant

  • Energy conversion system
    Patent number: 3992132
    Abstract: Relative motion is provided between a set of primary magnets positioned along a path of relative motion, and a set of secondary magnets positioned along the path of motion to confront the primary magnets. Such motion causes the primary magnets to displace the secondary magnets in directions transverse to the path. Power output means are driven by transverse displacement of the secondary magnets. The polarities of the magnets are such that the forces of magnetic attraction in one direction parallel to the path are substantially equal to the forces of magnetic repulsion in the opposite direction parallel to the path, whereby a minimum of energy is required to produce said relative motion. SUThis invention relates to an energy conversion system wherein primary motion in a given path produces secondary motion in a direction transverse to the given path.
