Abstract
Abstract A cooking computer for determining the cooking operation of a cooking apparatus, the computer having a stationary input means indicating selectable variables other than the weight of the meat item and 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. The weight input means is settable in relation to a selected variable of the stationary input means. The computer has a time period output means operatively associated with the input means to provide as an output, a cooking time period for the particular meat item computed as a function from the selection of both of the input means according to a cooking formula. Both of the input means are so constructed and arranged that when utilized for computing of said cooking time period for a particular meat item, the input means continuously indicates the selected weight and variable for that meat item even after the operation of the time period output means for the computed cooking time period.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
327 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 computercontroller device 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 computer-controller device determines and controls the cooking operation of said cooking apparatus, said device having a stationary input means indicating selectable variables other than the weight of a meat item, said device 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 weight input means being settable in relation to a selected variable of said stationary input means, said device having a time period output means operatively associated with both of 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 the selection of both of said input means whereby said controlling means is adapted to operate said heating means for said computed cooking time period, said device having operating means for operating said time period output means and said controlling means for said computed cooking time period when said operating means is activated, both of said input means, when utilized for the computing of said cooking time period for said particular meat item, continuously indicate the selected weight and variable for said particular meat item even after the operation of said time period output means for said computed cooking time periOd until said input means are utilized for causing the computation of a cooking time period for another meat item where the weight and selected variable are to be different from said particular meat item.
Claim 2
Dependent Claim
327 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 computercontroller device 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 computer-controller device determines and controls the cooking operation of said cooking apparatus, said device having a stationary input means indicating selectable variables other than the weight of a meat item, said device 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 weight input means being settable in relation to a selected variable of said stationary input means, said device having a time period output means operatively associated with both of 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 the selection of both of said input means whereby said controlling means is adapted to operate said heating means for said computed cooking time period, said device having operating means for operating said time period output means and said controlling means for said computed cooking time period when said operating means is activated, both of said input means, when utilized for the computing of said cooking time period for said particular meat item, continuously indicate the selected weight and variable for said particular meat item even after the operation of said time period output means for said computed cooking time periOd until said input means are utilized for causing the computation of a cooking time period for another meat item where the weight and selected variable are to be different from said particular meat item.
Claim 3
Dependent Claim
21 words
A cooking apparatus as set forth in claim 1 wherein said device has means visually indicating said computed cooking time period.
Claim 4
Dependent Claim
21 words
A cooking apparatus as set forth in claim 1 wherein said stationary input means indicates a variable of meat cooking doneness.
Claim 5
Dependent Claim
20 words
A cooking apparatus as set forth in claim 1 wherein said stationary input means indicates a variable of meat type.
Claim 6
Dependent Claim
27 words
A cooking apparatus as set forth in claim 1 wherein said stationary input means indicates a variable of meat cooking doneness and a variable of meat type.
Claim 7
Dependent Claim
35 words
A cooking apparatus as set forth in claim 1 wherein said stationary input means comprises a stationary scale, said weight input means comprising a movable scale adjacent said stationary scale to be selectably alignable therewith.
Claim 8
Dependent Claim
25 words
A cooking apparatus as set forth in claim 1 wherein said time period output means comprises means for visually indicating said computed cooking time period.
Claim 9
Dependent Claim
35 words

Claim 10
Dependent Claim
80 words
A cooking apparatus as set forth in claim 8 wherein said means for visually indicating said computed cooking time period has means for continuously indicating said computed cooking time period even after the operation of said time period output means for said computed cooking time period until said input means are utilized for causing the computation of a cooking time period for another meat item where the weight and selected variable are to be different from said particular meat item.
Claim 11
Dependent Claim
55 words
