    • A digital cutoff system comprising a weighing scale for producing analog signals in accordance with the desired weights of a plurality of materials successively placed upon the scale, analog-to-digital converter means for changing the analog signals to digital signals, means operable while one or more of the materials are upon the scale for resetting the converter means to cancel the digital signals corresponding to said one or more materials, and circuit means for producing a cutoff signal in response to digital signals corresponding to the desired weight of each of said plurality of materials. By resetting the converter means after each material is weighed and while the load is upon the scale, noncumulative weighing of multiple materials is accomplished with digital control of each material.
    • 一种数字切断系统,包括用于根据连续放置在秤上的多种材料的期望重量产生模拟信号的称重秤,用于将模拟信号改变为数字信号的模拟 - 数字转换器装置, 更多的材料是按照用于复位转换器装置来取消对应于所述一种或多种材料的数字信号的标度的电路装置,以及用于响应于对应于每个所述多个材料的期望重量的数字信号产生截止信号的电路装置 材料 通过在每个材料称重后重置转换器装置,并且当负载处于秤上时,通过对每种材料的数字控制来实现多种材料的非累积称重。
