Abstract
Abstract A computer-controller device for controlling the cooking operation of a cooking apparatus, the device having a manually settable weight input for indicating a single selected indicated weight applicable to all meat items and corresponding to the weight of a particular meat item to be cooked. The device has a second manually settable input for indicating a selected variable under other than the weight of the meat. The device has a timer that has a time period output operatively associated with the inputs to provide as an output a cooking time period for the particular meat item computed as a function of both of the inputs. The timer has a time period setting indicator operatively interconnected to the inputs to indicate the computed cooking time period as selected by the inputs. The timer has a reference means movable relative to the indicator to indicate lapsing time during the running of the computed cooking time period.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
280 words
A cooking apparatus having a source of energy and an oven provided with heating means for heating the same when said heating means is operated by being operatively interconnected to said source of energy, said apparatus having a cooking computer provided with controlling means for operatively interconnecting said source of energy to said heating means to operate the same for a period of cooking time as computed by said computer whereby said cooking computer determines and controlls the cooking operation of said cooking apparatus, said computer having a manually settable weight input means for indicating a single selected indicated weight applicable to all meat items and corresponding to the weight of a particular meat item to be cooked, said computer having a second manually settable input means for indicating a selected variable other than the weight of the meat, said computer having a timer that has a time period output means operatively associated with said input means and said controlling means to provide as an output said cooking time period for said particular meat item computed as a function from both of said input means whereby said controlling means is adapted to operate said heating means for said computed cooking time period, said timer having a time period setting indicator operatively interconnected to said input means to indicate said computed cooking time period as selected by said input means, said timer having a reference means movable relative to said indicator to indicate elapsing time during the running of said compUted cooking time period, said indicator continuously indicating said computed cooking time period even though said reference means is moving relative thereto during the running of said computed cooking time period.
Claim 2
Dependent Claim
280 words
A cooking apparatus having a source of energy and an oven provided with heating means for heating the same when said heating means is operated by being operatively interconnected to said source of energy, said apparatus having a cooking computer provided with controlling means for operatively interconnecting said source of energy to said heating means to operate the same for a period of cooking time as computed by said computer whereby said cooking computer determines and controlls the cooking operation of said cooking apparatus, said computer having a manually settable weight input means for indicating a single selected indicated weight applicable to all meat items and corresponding to the weight of a particular meat item to be cooked, said computer having a second manually settable input means for indicating a selected variable other than the weight of the meat, said computer having a timer that has a time period output means operatively associated with said input means and said controlling means to provide as an output said cooking time period for said particular meat item computed as a function from both of said input means whereby said controlling means is adapted to operate said heating means for said computed cooking time period, said timer having a time period setting indicator operatively interconnected to said input means to indicate said computed cooking time period as selected by said input means, said timer having a reference means movable relative to said indicator to indicate elapsing time during the running of said compUted cooking time period, said indicator continuously indicating said computed cooking time period even though said reference means is moving relative thereto during the running of said computed cooking time period.
Claim 3
Dependent Claim
16 words
A cooking apparatus as set forth in claim 1 wherein said indicator is a rotatable scale.
Claim 4
Dependent Claim
23 words
A cooking apparatus as set forth in claim 2 wherein said reference means comprises a rotatable member rotatable relative to said rotatable scale.
Claim 5
Dependent Claim
45 words
A cooking apparatus as set forth in claim 3 wherein said computer has an actuating means operatively associated with said timer to cause said timer to run for said computed cooking time period and thereby operate said cooking apparatus when said actuating means is actuated.
Claim 6
Dependent Claim
17 words
A cooking apparatus as set forth in claim 4 wherein said actuating means comprises said rotatable member.
Claim 7
Dependent Claim
52 words
A cooking apparatus as set forth in claim 1 wherein said indicator comprises a rotatable scale movable relative to said reference means in response to the setting of said input means whereby the position of said scale relative to said reference means provides said visual indication of said computed cooking time period.
Claim 8
Dependent Claim
24 words
A cooking apparatus as set forth in claim 6 wherein said reference means comprises a rotatable push button concentrically disposed with said rotatable scale.
Claim 9
Dependent Claim
38 words
A cooking apparatus as set forth in claim 7 wherein said push button has a reference member thereon that aligns with said scale to indicate the computed cooking time period before the running of said cooking time period.
Claim 10
Dependent Claim
53 words
A cooking apparatus as set forth in claim 8 wherein said push button rotates relative to said scale during the running of said timer for said computed cooking time period whereby said reference member of said push button moves relative to said scale to indicate the remaining time of said cooking time period.
Claim 11
Dependent Claim
36 words
A cooking apparatus as set forth in claim 9 wherein said computer has means for returning said push button to its beginning position relative to said scale at the termination of said computed cooking time period.
Claim 12
Dependent Claim
39 words
A cooking apparatus as set forth in claim 10 wherein said push button is operatively associated with said timer to cause running thereof for said computed cooking time period when said push button is depressed relative to said scale.
Claim 13
Dependent Claim
55 words
A cooking apparatus as set forth in claim 11 wherein said push button has means returning the same to its undepressed condition at the termination of said computed cooking time period so that the running of the particular computed cooking time period can be repeated by merely again depressing said push button of said computer.
Claim 14
Dependent Claim
31 words
A cooking apparatus as set forth in claim 1 wherein said input means each comprises a rotatable knob rotatable relative to a scale therefor for visually selecting the desired input thereof.
Claim 15
Dependent Claim
53 words
A cooking apparatus as set forth in claim 13 wherein said indicator comprises a rotatable scale rotatable relative to said reference means, each input means having a gear train operatively interconnecting the respective knob to said indicator scale to rotate the same in a certain relation to the rotation of the respective knob.
Claim 16
Dependent Claim
67 words
A cooking apparatus as set forth in claim 14 wherein said certain relation of said gear trains causes said computed cooking time period to be based on a cooking formula wherein said time period is the result of a fixed constant times the square root of the selected weight by said weight input means plus an amount corresponding to a doneness selection of said second input means.
