Abstract
Abstract A digital cutoff system comprising a weighing scale, means for producing digital signals in accordance with load upon the scale, means for selecting a desired weight, and coincidence means for detecting coincidence between the digital signals and the desired weight and for detecting in at least one number place an additional digital signal greater than the desired digital signal in the number place. The additional digital signal forces the coincidence means to produce a cutoff signal even though the digital signals are greater than the desired weight.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
65 words
A digital cutoff system comprising, in combination, a weighing scale, means for producing digital signals in accordance with load upon the scale, means for selecting a desired weight, and coincidence means for detecting coincidence between the digital signals and the desired weight and for detecting in at least one number place an additional digital signal greater than the desired digital signal in said number place.
Claim 2
Dependent Claim
65 words
A digital cutoff system comprising, in combination, a weighing scale, means for producing digital signals in accordance with load upon the scale, means for selecting a desired weight, and coincidence means for detecting coincidence between the digital signals and the desired weight and for detecting in at least one number place an additional digital signal greater than the desired digital signal in said number place.
Claim 3
Dependent Claim
33 words
A digital cutoff system according to claim 1 wherein the means for selecting a desired weight includes double switch means for transmitting both digital signals in said number place to the coincidence means.
Claim 4
Dependent Claim
30 words
A digital cutoff system according to claim 1 wherein the coincidence means includes means for producing an overriding output signal for all places of significance less than said number place.
