Abstract: A stand alone venting apparatus for an enclosed space that converts open door and closed door emissions of a steam and hot air oven into cooler air and condensate, the apparatus comprising an expansion chamber, a condensing chamber and a chilling chamber. A capture hood is provided for capturing the open door emissions. An emissions inlet is provided for capturing the closed door emissions. The condensing chamber includes condensing tubes with each tube containing an interior and an exterior. The open door emissions are directed over the exterior of the condensing tubes and the closed door emissions are directed within the interior of the condensing tubes. The expansion chamber and chilling chambers work with the condensing chamber to further cool and condense the emissions. All emissions may be re-circulated back into the enclosed space without requiring ductwork to vent outside the enclosed space.

Abstract: An apparatus for treating food, the apparatus includes a housing having a lid, a base and a cavity defined therein. The cavity is separated into an upper chamber and lower chamber by a divider. Upper chamber is for holding food placed upon the divider. One or more steam sources provide steam to the upper and lower chambers. One or more infrared sources are position within the upper and lower chambers to directly heat the steam, the food or the divider. A pressure-controlled environment may be provided in the upper chamber. Uniformity and increased speed of heating the food is facilitated by direct heat transfer in the upper chamber and by indirect heat transfer from the conduction of heat through the divider from the lower chamber.

Abstract: A device for generating heat from an applied current, the device comprises a mixture of conductive particles and dielectric particles. The device includes at least one pair of electrodes disposed within the mixture to direct an applied current through the mixture to resistively heat the mixture. The device may further heat a liquid that flows through the mixture.

Abstract: The present application is directed to a system for verifying calibration of a temperature sensor comprising an above-ambient temperature verifier and a below-ambient temperature verifier. The above-ambient temperature verifier includes a first housing containing an ohmic material. At least one pair of electrodes is provided to direct an applied current through the ohmic material to heat the material. A well is provided within the ohmic material for accepting a temperature sensor. A compression assembly cooperates with the ohmic material to create intimate contact with the temperature sensor. An above-ambient reference temperature monitor maintains a calibrated temperature within the ohmic material. The below-ambient temperature verifier includes a second housing and a below-ambient reference temperature monitor to maintain a calibrated temperature of a below-ambient temperature medium.

Abstract: A steam generator system for rapidly creating steam by a direct conversion of electrical energy to heat in ionic, water molecules. The system generally includes a supply of water having an ionic content to be received by a heating tank for contacting current-carrying electrodes to produce steam in a continuous, intermittent, or a determinant amount, via a control system. Also possibly included are a water reservoir, filter, pump, check valve, and various optional embodiments of the heating tank. The present invention also permits for controlling the supplied current input to the electrodes by the combination of ionic content added to the water, water level as controlled by the pump, and a phase angle controller and current sensor of an electrical circuit.
