Claim 1

Independent Claim 271 words

An oven cooking monitor for automatically controlling the cooking, to a selected degree of doneness, of a plurality of food items requiring different cooking times, to permit food items to be loaded into an oven randomly and removed in the order in which each food item becomes done, comprising: a disconnectable probe for each food item, arranged to be inserted into the food item to sense its internal temperature; means connected to each probe for providing a signal varying with the internal temperature sensed by the probe; means for setting a reference temperature signal; means for comparing the temperature sensing signal from a probe with the reference signal and for providing an output signal when the sensed temperature matches the reference temperature; means connected to the comparison means for receiving an output signal arising from the attainment by any of the probes of the reference temperature and, in response to such an output signal, (a) indicating which probe has sensed the done food item and (b) switching the oven to a holding temperature to curtail further cooking, and, in response to disconnecting of the probe for the done food item, said means (a) stopping indicating of that probe as the one associated with the done food item and (b) switching the oven again to a cooking temperature, whereby cooking of the food items proceeds until the next food item has reached the desired degree of doneness, thereby permitting the different food items to be cooked and stored safely until removal while preventing any overcooking thereof, and indicating the order in which the food items become done and are to be removed.

Claim 4

Dependent Claim 58 words

Claim 7

Dependent Claim 260 words

An oven cooking method for automatically controlling the cooking, to a selected degree of doneness, of a plurality of food items requiring different cooking times, to permit food items to be loaded into the oven in random order and removed in the order in which the food items become done, comprising: placing food items into an oven, inserting a temperature-sensing probe into each food item of a type that provides a signal varying with the temperature sensed by the probe, said temperature sensing probe being connected to said oven, setting a reference temperature signal to correspond to the desired degree of doneness, using self-actuating comparison means to compare the sensed temperature signal with the reference temperature signal and to provide an output signal when the sensed and reference signals match, to indicate which probe is associated with the done food items, and to switch the oven to a holding temperature curtailing further cooking of the food items, removing the done food from the oven and disconnecting the probe for the done food item from the oven, and in response to the disconnecting of the probe associated with the done food item, said comparison means stopping the indication that a food item is done, and switching the oven again to a cooking temperature to resume cooking of the remaining food items, whereby cooking of the food items proceeds with each food item attaining the desired degree of doneness with overcooking automatically prevented, and with an indication of the order in which the food items become done and are to be removed.

Claim 8

Dependent Claim 260 words

An oven cooking method for automatically controlling the cooking, to a selected degree of doneness, of a plurality of food items requiring different cooking times, to permit food items to be loaded into the oven in random order and removed in the order in which the food items become done, comprising: placing food items into an oven, inserting a temperature-sensing probe into each food item of a type that provides a signal varying with the temperature sensed by the probe, said temperature sensing probe being connected to said oven, setting a reference temperature signal to correspond to the desired degree of doneness, using self-actuating comparison means to compare the sensed temperature signal with the reference temperature signal and to provide an output signal when the sensed and reference signals match, to indicate which probe is associated with the done food items, and to switch the oven to a holding temperature curtailing further cooking of the food items, removing the done food from the oven and disconnecting the probe for the done food item from the oven, and in response to the disconnecting of the probe associated with the done food item, said comparison means stopping the indication that a food item is done, and switching the oven again to a cooking temperature to resume cooking of the remaining food items, whereby cooking of the food items proceeds with each food item attaining the desired degree of doneness with overcooking automatically prevented, and with an indication of the order in which the food items become done and are to be removed.
