Abstract: An oven rack is received in an oven above a lower surface of the chamber and having a bake element mounted in the chamber either above or below the lower surface. The oven rack is configured to support cooking ware on one of the lower surface of the oven chamber or on rack shelf portions provided in sidewalls of the chamber. The rack includes a first portion having a substantially planar top surface, a second portion having a substantially planar lower surface spaced from the top surface and it is also configured to support the rack in one of the rack shelf portions or on the lower surface of the oven chamber. First and second walls extend between these first and second portions whereby the walls have a first dimension slightly greater than a height from the bottom surface of the oven chamber to a top of the bake element when the bake element is mounted above the lower surface.

Abstract: A programmable computer-controlled fast response infrared heating system capable of precise individual zone control and especially useful for thermoforming of plastic sheets comprises an array of fast response quartz heaters on a platen, a terminal box having a CPU and mounted on and moving with the platen and which needs only one power line to it and which distributes the power to the heaters sequentially on a milli-second time basis with an essentially constant power output to each heater. The power is three phase and switching occurs only when the voltage over a relay is zero to minimize RFI/EMI emissions. The CPU is interfaced with a general purpose computer at the operator's console and a touch activated display showing the percent of available power being supplied to each heater. The operator by touch command can change the percentage of applied power for any one heater or the total power supplied to the whole of the array.
