Patent number: 6955589Abstract: A magnetorheological fluid delivery system includes a mixing and tempering vessel. Fluid is admitted to the vessel via a plurality of tangential ports, creating a mixing of the fluid in the vessel and promoting homogeneity. Fluid may be reconstituted in the vessel by metered addition of carrier fluid. A fixed-speed centrifugal pump disposed in the vessel pressurizes the system. Fluid is pumped through a magnetic-induction flowmeter and a magnetic flow control valve having solenoid windings whereby MR fluid is magnetically stiffened to restrict flow. A closed-loop feedback control system connects the output of the flowmeter to performance of the valve. A nozzle having a slot-shaped bore dispenses MR fluid for re-use in the work zone.Type: GrantFiled: May 22, 2001Date of Patent: October 18, 2005Assignee: QED Technologies, Inc.Inventors: William Kordonski, Stephen Hogan, Jerry Carapella

Patent number: 6506102Abstract: An improved system for magnetorheological finishing of a substrate comprising a vertically oriented bowl-shaped carrier wheel having a horizontal axis. The carrier wheel is preferably an equatorial section of a sphere, such that the carrier surface is spherical. The wheel includes a radial circular plate connected to rotary drive means and supporting the spherical surface which extends laterally from the plate. An electromagnet having planar north and south pole pieces is disposed within the wheel, within the envelope of the sphere and preferably within the envelope of the spherical section defined by the wheel. The magnets extend over a central wheel angle of about 120° such that magnetorheological fluid is maintained in a partially stiffened state ahead of and beyond the work zone. A magnetic scraper removes the MRF from the wheel as the stiffening is relaxed and returns it to a conventional fluid delivery system for conditioning and re-extrusion onto the wheel.Type: GrantFiled: February 1, 2001Date of Patent: January 14, 2003Inventors: William Kordonski, Stephen Hogan, Jerry Carapella, Andrew S.

Patent number: 6309285Abstract: A magnetic wiper for removing magnetorheological fluid from a carrier surface includes a horseshoe magnet having north and south polepieces elongated in a first direction orthogonal to a second direction of magnetic flux in the magnet. The polepieces are generally parallel at their free ends in the first direction and are preferably arcuate such that the inner polepiece forms a trough for receiving magnetorheological fluid removed from the carrier surface and conveying it to an exit tube. The free ends are shaped to conform closely to the shape of the carrier surface, forming a narrow gap therebetween containing a magnetic fringing field extending beyond the free ends.Type: GrantFiled: June 14, 2001Date of Patent: October 30, 2001Inventors: William Kordonski, Gennadi Gorodkin, Stephen Hogan, Arpad Sekeres

Patent number: 5971835Abstract: A fluid having magnetorheological (MR) properties and including a finely-divided abrasive material is directed through a non-ferromagnetic nozzle disposed axially of the helical windings of an electric solenoid. The MR fluid may contain magnetosoft or magnetosolid particles or mixtures thereof. A magnetic field created by the solenoid orients and aligns the magnetic moments of the particles to form fibrils thereby stiffening the flowing MR fluid which, when ejected from the nozzle, defines a highly-collimated jet. Collimation of the MR material persists for a significant time outside the magnetic field, permitting use of the abrasive jet to shape and/or polish the surface of a workpiece at some distance from the nozzle. The jet is directed into a shroud against a workpiece mounted for multiple-axis rotation and displacement to meet predetermined material removal needs for shaping. The solenoid may be similarly mounted to also move the jet over the surface of the workpiece.Type: GrantFiled: March 25, 1998Date of Patent: October 26, 1999Assignee: QED Technologies, Inc.Inventors: William I.

Patent number: 5951369Abstract: An improved system for increasing the effectiveness of magnetorheological finishing of a substrate. An inline flowmeter is close-loop linked to the rotational speed of a pressurizing pump to assure that the flow of magnetorheological fluid (MRF) to the work zone is constant. A simplified capillary viscometer is disposed in the fluid delivery system at the exit thereof onto the wheel surface. Output signals from the flowmeter and the viscometer pressure sensor are sent to a computer which calculates the viscosity of MRF being delivered to the work zone and causes replenishment of carrier fluid to the work-concentrated MRF to return the viscosity to aim to assure that a constant concentration of magnetic solids is being provided to the work zone.Type: GrantFiled: January 6, 1999Date of Patent: September 14, 1999Assignee: QED Technologies, Inc.Inventors: William I.
