Publication number: 20030102303Abstract: Temperature self-regulating food delivery systems are provided having a magnetic induction heater (32, 126) and an associated food container (76, 124) equipped with an essentially permanent ferromagnetic heating element (82, 100, 128). The heater (32, 126) and heating elements (82,100, 128) are designed so as to heat the element (82, 100, 128) to a user-selected regulation temperature when the elements (82, 100, 128) are coupled with the heater's magnetic field, and to maintain the temperature in the vicinity of the regulation temperature indefinitely temperature regulation is a heating achieved by periodically determining at least two parameters of the heaters resonant circuits related to the amplitude of the resonant current passing therethrough during heating and responsively altering the field strength of the magnetic field. Preferably, the value of the resonant circuit amplitude and the rate of change of the amplitude are determine.Type: ApplicationFiled: January 13, 2003Publication date: June 5, 2003Inventors: Brian L. Clothier, Amil J. Ablah

Publication number: 20030095034Abstract: A temperature-regulating induction heating system is provided which comprises an induction heater (20) having apparatus (36, 38, 40) for receiving RFID transmissions and an induction heatable object (22) with an RFID tag (50). The heater (20) includes a component (28) for generating a magnetic field, control circuitry including a microprocessor (32) coupled with the component (28) for selectively initiating and terminating generation of a magnetic field; the receiving apparatus (36, 38, 40) provides information to the microprocessor (32) causing initiation of a heating algorithm for the object (22). In preferred forms, the tag (50) and apparatus (36, 38, 40) are designed for two-way information transfer, thereby permitting continuous updating of the information carried by tag (50). In this way, if induction heating of the object (20) is interrupted, it may be resumed to nevertheless achieve a desired regulation temperature.Type: ApplicationFiled: December 5, 2002Publication date: May 22, 2003Inventor: Brian L.

Publication number: 20030006633Abstract: An induction heatable body (22) that quickly heats to a desired temperature, retains heat long enough to be used in almost any application, and develops no “hot spots” even when heated by a heating source having an uneven magnetic field distribution. The induction-heatable body (22) achieves the foregoing while remaining relatively lightweight, inexpensive and easy to manufacture. The induction-heatable body (22) includes a plurality of induction-heatable layers (32a, b, c) each sandwiched between alternating layers of heat retentive material (34a, b, c). The induction-heatable layers (32a, b, c) consist of sheets of graphite material that can be inductively heated at magnetic field frequencies between 20 and 50 kHz. The heat-retentive layers (34a, b, c) consist of solid-to-solid phase change material such as radiation cross-linked polyethylene.Type: ApplicationFiled: May 20, 2002Publication date: January 9, 2003Applicant: THERMAL SOLUTIONS, INC.Inventor: Brian L.

Patent number: 5954984Abstract: A heat retentive, temperature self-regulating, food retaining apparatus (10) includes a body (12), heat retentive core (14) and magnetic induction heating element (16). The body (12) includes a substantially rigid, heatable, food-contacting wall (18) defining a cavity (24). The core (14) is positioned in the cavity (24), and in thermal contact with the wall (18) for selective heating of the wall (18). The core (14) includes a solid state phase change material for storing latent heat during a solid-to-solid phase transformation at a phase transformation temperature. A resilient material is in contact with the phase change material to permit expansion of the phase change material during a phase transformation. The heating element (16) is in thermal contact with the core (14) for heating the core (14) to a temperature above the phase transformation temperature to effect a phase transformation in the phase change material.Type: GrantFiled: July 30, 1997Date of Patent: September 21, 1999Assignee: Thermal Solutions Inc.Inventors: Amil J.
