专利汇可以提供Automatic dry coke weight system专利检索，专利查询，专利分析的服务。并且An analog electrical system utilizes a signal from a coke weighing system and a signal from a coke moisture gauge to correct for prior errors in hopper weighings due to delivery overshoot as well as moisture variations in prior batches of coke.，下面是Automatic dry coke weight system专利的具体信息内容。
1. Apparatus for automatically measuring and controlling the net dry weight of discrete quantities of moisture-containing material, comprising: a. means for producing a first signal indicative of the actual weight of each discrete quantity of material; b. means for producing a second signal indicative of the moisture content of said material; c. means for producing a third signal indicative of the target dry weight for each weighing of said material; d. means adapted to receive said first, second and third signals and compute and store a fourth signal indicative of the target dry weight, plus the difference between said target dry weight and the actual dry weight of the instant weighing, plus the error in dry weight existing after the next preceding weighing; e. means adapted to receive said second signal and said fourth signal and compute and store a fifth signal indicative of the actual desired weight for the next weighing; f. timing means for controlling when said fourth and fifth signals are computed and stored; and g. means for shutting off the supply of said material to said next weighing when said first signal equals said fifth signal.
2. Apparatus as recited in claim 1, in which means (d) comprises: i. means for converting said first signal into an adjusted signal indicative of the actual dry weight of the instant weighing; ii. means for summing said third signal, said adjusted signal, and a signal indicative of the error in dry weight existing after the next preceding weighing; iii. means adapted to sample the signal from means (ii) during a compute period and to store said signal during all other periods; and iv. means adapted to store the output of means (iii) during said compute period and to sample said output during all other periods.
