Patent number: 7491916Abstract: A portable induction tool is provided for soldering or brazing sections of metal pipe together. A work coil head (with induction coil) is U-shaped, allowing placement of the head around lengths of pipe, heating a susceptor (e.g., the pipe) to form a joint, and then to be withdrawn after the pipe joint is made. In one form, the tool uses heat pipes to remove thermal energy from the head, and also a heat exchanger for higher-powered units. Power capacitors are generally included with the induction (work) coil to create a tank circuit of a resonant frequency. The induction coil uses Litz wire, copper tubing, or heat pipes with a conductive outer skin to carry the high-current being delivered to the induction coil. The induction coil has a general racetrack configuration, which is typically wound in a U-shape (or as a semicircle) as a single winding, with multiple turns.Type: GrantFiled: January 31, 2007Date of Patent: February 17, 2009Assignee: Nexicor LLCInventors: John P. Barber, Robert C. Cravens, II, Antonios Challita, Susan A. Stanton

Patent number: 7399949Abstract: An improved induction heating apparatus is provided for attaching membrane roofs. A top membrane layer is attached to attachment disks that hold sheets of thermal insulation to the top of roof substrates. The heating apparatus emits a magnetic field that raises the temperature of the disks and a heat-activated adhesive on top of the disks which, after cooling, becomes adhered to the bottom surface of the top membrane layer. The disks in turn are attached via fasteners to the substrate portion of the roof structure. The apparatus includes a set of bottom guides that allow a user to find the attachment disks mechanically, without actually seeing those disks beneath the top membrane layer. A fine locator circuit is provided, using a magnetic field, and the apparatus allows a user to stand upright while operating the apparatus.Type: GrantFiled: March 30, 2005Date of Patent: July 15, 2008Assignee: Nexicor LLCInventors: John P. Barber, Robert C. Cravens, II, Antonios Challita, Susan A. Stanton

Patent number: 7141768Abstract: A device for fastening surfaces together in an effective, efficient, and preferably reversible bond is disclosed. This device is particularly useful in the construction industry for fastening roll goods, such as wall coverings, or mill work, such as moldings, to surfaces, such as walls. The fastening device comprises a susceptor sheet, preferably having a thickness of no greater than about 2 mils, and a heat-activateable adhesive on at least one surface of the susceptor, wherein adhesive is placed on the substrate in a very carefully and specifically-defined manner. The fastening device is activated by induction heating, preferably by a hand-held induction tool. The method of fastening surfaces together utilizing the fastening device described above is also disclosed.Type: GrantFiled: April 24, 2001Date of Patent: November 28, 2006Assignee: Nexicor, LLCInventors: Adam G. Malofsky, Bernard M. Malofsky, William H. Mann

Patent number: 6849837Abstract: A method for using magnetic fields to heat magnetically susceptible materials within and/or adjacent to adhesives, so as to bond, bind, or fasten solid materials to one another. The system uses alternating magnetic fields that induce eddy currents and generate heat within susceptors. An induction heating tool is used to emit the magnetic field at its work coil, and an electronic controller measures the energy being used by a power converter that generates the alternating current driving the work coil which creates the magnetic field. The heating tool is used in a method of adhesive bonding in which the thickness of the conductive layer of the susceptor is in the range of 0.01-3.0 mils, or the heating event time interval is in the range of 0.05-10.0 seconds, or the average power density of the magnetic field at the susceptor is in the range of 10-5000 Watts per square inch.Type: GrantFiled: September 12, 2003Date of Patent: February 1, 2005Assignee: Nexicor LLCInventors: Edward A. Riess, Adam G. Malofsky, John P. Barber, David P. Bauer

Patent number: 6710314Abstract: An apparatus and system for using magnetic fields to heat magnetically susceptible materials within and/or adjacent to adhesives, resins, or composites so as to reversibly or irreversibly bond, bind, or fasten opaque or non-opaque solid materials to one another. The system makes use of the effect that alternating magnetic fields induce eddy currents and generate heat within susceptors, and the effect that alternating magnetic fields additionally induce magnetic hysteresis that occurs in magnetic materials and thereby generate heat. An induction heating tool is used to emit the magnetic field at its work coil, and an electronic controller measures the energy being used by a power converter that generates the alternating current driving the work coil which creates the magnetic field. The distance between the susceptor and work coil is repeatedly analyzed based upon the power converter's input energy, and the work coil is driven at a repeatedly corrected power level during the heating cycle.Type: GrantFiled: November 22, 2002Date of Patent: March 23, 2004Assignee: Nexicor LLCInventors: Edward A. Reiss, Adam G. Malofsky, John P. Barber, Gary L. Claypoole, Robert Carl Cravens, II, David R. Pacholok, Charles A. Kuecker
