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.

Claim 1
Independent Claim
171 words
A digital cutoff system comprising, in combination, a condition responsive digital signal source for each place in a number to be selected, the number being in accordance with a desired condition, each source producing a desired signal when the condition corresponds to a desired digit, at least one of the sources producing an additional digital signal simultaneously with the respective desired signal whenever the condition is higher by at least one digit, and circuit means responsive to the desired digital signals in the absence of the additional digital signal for producing a normal output signal for each place in the number and responsive to the additional digital signal to produce an overriding output signal for all places of significance less than the place corresponding to the additional digital signal, overriding output signals taking the place of normal output signals resulting in one output signal for each place in the number, and gate means for receiving the output signals and for producing a cutoff signal to control the magnitude of the condition.
Claim 2
Dependent Claim
