Patent number: 6995345Abstract: An RF heating system for generating precision stray RF fields that can be used to heat materials. The RF heating system includes an RF power supply for generating RF signals and an electrode apparatus that is coupled to the RF power supply. An electrode apparatus according to the present invention has many advantages over existing electrode apparatuses. For example, the electrode apparatus is easier to manufacture, easier to duplicate, easier to control the manufacturing tolerances on the electrode system, and easier to correctly place and design the resulting RF stray field.Type: GrantFiled: September 23, 2004Date of Patent: February 7, 2006Assignee: Codaco, Inc.Inventor: Timothy D. Gorbold

Publication number: 20040159654Abstract: A susceptor composition that can bond two or more layers or substrates to one another and that can be used to coat or cut a substrate. The susceptor composition is activated in the presence of radio frequency (RF) energy. In one embodiment, the susceptor composition of the present invention comprises a susceptor and a carrier. The carrier and susceptor are blended with one another and form a mixture, preferably a uniform mixture. The susceptor is present in an amount effective to allow the susceptor composition to be heated by RF energy. In a preferred embodiment, the susceptor also functions as an adhesive. The susceptor is an ionic or polar compound and acts as either a charge-carrying or an oscillating/vibrating component of the susceptor composition. The susceptor generates thermal energy in the presence of an RF electromagnetic or electrical field (hereafter RF field).Type: ApplicationFiled: June 27, 2003Publication date: August 19, 2004Applicant: Codaco, Inc.Inventors: William J. Ryan, Manfred Luttinger, Bhima Vijayendran, Jonathan M. Gorbold, Lewis Hamilton, Steve Skewes, Gary C. Adishian, Daniel J. Lincoln, Robert Sengillo, John Cunliffe

Patent number: 6649888Abstract: An RF heating system for bonding a first element to a second element. In one embodiment, the RF heating system includes: (a) a composition, which functions as an adhesive, interposed between the first and second elements, the composition including an ionomer and a polar carrier, wherein the ionomer and/or the carrier are present in amounts effective to allow the composition to be headed by a fringe RF field; and (b) a radio frequency (RF) heating apparatus for producing the fringe RF field.Type: GrantFiled: October 25, 2001Date of Patent: November 18, 2003Assignee: Codaco, Inc.Inventors: William J. Ryan, Francisco Chiarilli, Gary C. Adishian, Jonathan M. Gorbold

Patent number: 6617557Abstract: An RF heating system. In one aspect of the present invention, the RF heating system includes a first elongated electrode connected to a first node within an impedance matching circuit and a second elongated electrode connected to a second node within the impedance matching circuit, wherein (a) a first portion of the first electrode and a first portion of the second electrode are adjacent to and substantially parallel with each other, (b) a second portion of the first electrode is angled in a direction away from the second electrode, (c) a second portion of the second electrode is angled in a direction away from the first electrode, and (d) a stray electromagnetic field is generated in a region above the space between the first portion of the first electrode and the first portion of the second electrode, whereby the generated stray field can be used to heat a composition when the composition is placed in the region.Type: GrantFiled: May 31, 2001Date of Patent: September 9, 2003Assignee: Codaco, Inc.Inventors: William J.
