Operational modes for a cooking appliance employing combination cooking technology

A cooking appliance includes a controller for establishing a plurality of operating modes for heating an oven cavity. Specifically, the controller establishes one of a pre-heat mode, a ready mode, a first low power mode and a second low power mode for controlling a temperature of the oven cavity. Upon selecting a temperature for the oven cavity, the controller operates a radiant heating device, a convection fan and a convection heating device at full power to establish the selected temperature. After the selected temperature is achieved, the controller switches to a ready mode and reduces heat output of both the radiant heating device and the convection heating device, while also reducing fan speed. After respective periods of time in which a door of the appliance is not opened, the controller switches to first and second low power modes to conserve energy.

Low thermal inerta scanning adiabatic calorimeter

A new adiabatic scanning calorimeter allows the thermal mass of a high-pressure reaction vessel to be dynamically compensated during a test. This allows the effective Φ factor for the experiment to be reduced to 1.0 without the use of complex pressure balancing equipment. Endothermic events can be quantified and sample specific heats can be measured. The time required for test completion is much shorter than for conventional adiabatic calorimeters, thus considerably improving apparatus productivity. The sensitivity to exotherm detection is at least as good as existing adiabatic calorimeters employing the Heat-Wait-Search strategy, but does depend on the temperature-scanning rate. In addition, the heat of reaction is obtained without reference to the heat capacity of the sample, pressure is measured continuously, reactants may be injected into the test vessel and the sample can be mixed during the test.
