Patent number: 5839485Abstract: A method and apparatus for filling a container with a magnetic material using an electromagnetic valve and a demagnetizing circuit to control the flow and properties of the material. Initially an empty container is placed under a fill tube through which the material will be supplied to the container. In the filling process an auger located inside of the fill tube rotates to move the material through the fill tube. When the container is filled, the auger stops rotating and the electromagnetic valve is actuated. The electromagnetic valve supplies a magnetic field which holds the material particles in place, plugging the fill tube with the material. The filled container is removed from the fill tube and an empty container is put in its place. When the electromagnetic valve is switched off, a demagnetizing circuit is activated. After the material particles are demagnetized the auger is switched on and the material flows again to fill the container.Type: GrantFiled: October 12, 1995Date of Patent: November 24, 1998Assignee: Xerox CorporationInventors: Paul M. Wegman, Mikhail Vaynshteyn, David M. Korvick
