| 219411000 | With infrared generating means | 9 |
| 20080203083 | SINGLE WAFER ANNEAL PROCESSOR - A thermal processor is adapted for annealing substrates. The processor has a sealed process chamber. Air is excluded from the process chamber during processing to avoid oxidation of substrate surfaces, such as copper surfaces. The substrate temperature is controlled by selectively positioning the substrate between a hot plate and a cold plate operating at steady state conditions. During loading and/or unloading, the air flow is induced over the substrate. This keeps the substrate at a temperature low enough to avoid oxidation, even though the heater may remain on. | 08-28-2008 |
| 20090045185 | FOOD HOLDING OVEN WITH MATTE FINISH FOOD HOLDING TRAY - A food holding oven, which is used to keep previously-prepared foods hot until they are served, is provided with a food holding tray having a roughened or matte finish. The matte finish keeps the tray's service temperature lower and easier to handle than prior art trays with highly reflective, shiny surfaces. When the matte-finish tray is held under a principally pure infrared heat source for long periods of time, the tray's surface temperature prevents food from being burned and reduces the likelihood of a user being burned. | 02-19-2009 |
| 20090057293 | FOOD HOLDING OVEN AND TRAY WITH INFRARED HEAT WEIGHTED AROUND THE TRAY PERIPHERY - A food holding oven holds pre-cooked food at a selected temperature by heating the food in a food-holding tray using infrared energy obtained from a multi-layer planar infrared energy source above the food. The infrared emitted from the planar IR source is produced by electrically heated windings in either a boustrophedonic or crenellated pattern, the loops and crenellations of which are more closely spaced near the edge of the heater than they are away from edges of the heater. The IR from the heater is directed toward the tray such that there is more IR directed at the tray edges than is directed toward the tray interior regions. | 03-05-2009 |
| 20090114636 | CONTROLLER FOR A FOOD HOLDING OVEN - A controller for a food holding oven determines one or more time periods during each of which heat is directed at a pre-cooked food item. By controlling the heat intensity and the time over which different amounts of heat are provided to different types of pre-cooked food items, the time during which a particular type of pre-cooked food item can be kept palatable is maximized. | 05-07-2009 |
| 20120241435 | RADIANT TUBE BROILER - An emitter tube has an outer surface and an inner surface, wherein the inner surface defines a cavity of the emitter tube, and the cavity of the emitter tube is adapted for receiving food. An outer tube has an inner surface that defines a cavity of the outer tube, and the emitter tube is positioned in the cavity of the outer tube. A heating unit is for heating the outer surface of the emitter tube so that heat energy is transferred by conduction from the outer surface of the emitter tube to the inner surface of the emitter tube, and the inner surface of the emitter tube emits infrared radiant energy into the cavity of the emitter tube so that a majority of the energy that is transferred to the food within the emitter tube is in the form of infrared radiant energy. | 09-27-2012 |
