Abstract: A dense-end monitor and controller is provided for a cigarettemaking machine of the dense-ending type. In a preferred embodiment, a density gauge is positioned adjacent to the moving cigarette rod for providing a first signal varying with the occurrences of dense portions in the tobacco rod. Another signal is supplied for each cutting action of the rod cutter by means synchronized to the rod cutter. Correlation waveform generators generate sawtooth and triangular-shaped waveforms which are phase-synchronized with the dense portion pulses in the density gauge signal. Two output signals, one representing deviation of the dense portions from their proper position at the ends of the cut cigarettes, and the other representing the relative increase in the amount of tobacco in the dense portions, are provided for visual display and machine control purposes. The signals are obtained by correlating the density signal with the triangularshaped waveform and by sampling the sawtooth-shaped waveform at the instant the cutter signal is generated. The output signals are free of any interdependence of information content.

Abstract: A PENETRATING RADIATION GAUGE INCLUDES A PULSED X-RAY SOURCE FOR DETERMINING WALL THICKNESS OF ARTICLES MOVING PAST THE SOURCE. THE GUAGE IS CONTINUOUSLY STANDERDIZED BY RESPECTIVELY PLACING IN THE SOURCE RADIATION FIELD FIRST AND SECOND DIFFERENT STANDARD SAMPLES BETWEEN FIRST AND SECOND DIFFERENT PAIRS OF ADJACENT ARTICLES. A DETECTOR RESPONDS TO THE LEVEL OF RADIATION ABSORBED BY ARTICLES WHILE THICKNESS IN BEING MEASURED AND BY THE SAMPLES WHILE STANDARDIZATION IS BEING PERFORMED TO DERIVE AN OUTPUT SIGNAL EXPONENTIALLY RELATED TO THE RADIATION ABSOBPTION PROPERTIES OF THE ARTICLES AND SAMPLES. A LINEARIZING NETWORK RESPONSIVE TO THE DIRECTOR CONVERTS THE EXPONENTIAL RELATIONSHIP INTO A STRAIGHT LINE FUNCTION WHEREBY A LINEAR RELATIONSHIP BETWEEN THE MAGNITUDE OF THE DETECTOR OUTPUT SIGNAL AND THE ABSORPTION PROPERTY IS DERIVED. WHILE THE LINEARIZING NETWORK IS DERIVING A SIGNAL INDICATIVE OF THE RADIATION ABSORPTION PROPERTIES OF THE FIRST SAMPLE, THE STRAIGHT LINE RELATIONSHIP IS ADJUSTED SO THAT THE GAUGE RESPONSE IS A POINT ON THE LINE HAVING A PREDETERMINED OUTPUT SIGNAL CORRESPONDING WITH THE ABSORPTION PROPERTIES OF THE FIRST SAMPLES. WHILE THE LINEARIZING NETWORK IS DERIVING A SIGNAL INDICATIVE OF THE OBSORPTION PROPERTIES OF THE SECOND SAMPLES, THE SLOPE OF THE LINE ADJUSTED SO THAT THE GUAGE DERIVES AN OUTPUT SIGNAL HAVING A PREDETERMINED MAGNITUDE CORRESPONDING WITH THE OBSORPTION PROPERTIES OF THE SECOND SAMPLES

Abstract: DISCLOSED ARE A SYSTEM FOR AND METHOD OF OF CONTROLLING PROCESSES OF PAPER SHEET MANUFACTURE. IN RESPONSE TO BASIS WEIGHT SIGNALS AT THE PROCESS WET AND DRY ENDS, AS WELL AS A MOISTURE SIGNAL FROM THE DRY END, A PROPORTIONALITY CONSTANT INDICATIVE OF THE SHEET FIBER FRACTION AT THE WET END IS COMPUTED. THE PROPORTIONALITY CONSTANT IS REPEATEDLY RECOMPUTED ONCE EVERY TWENTY MINUTES AND IS STORED BETWEEN RECOMPUTATIONS. THE PROPORTIONALITY CONSTANT IS COMBINED WITH A WET END BASIS WEIGHT OUTPUT DERIVED AT A LATER TIME THAN THE ABOVE SIGNALS TO INDICATE FIBER CONTENT AT THE DRY END AND CONTROL FIBER FLOWING ONTO THE PAPER MAKING HEADBOX. CONTROL OF FIBER FLOW INTO THE HEADBOX AND MOISTURE REMOVED BY THE DRYING SECTIONS IS RESPECTIVELY IN REPONSE TO INDICATIONS OF THE AMOUNT OF FIBER AND MOISTURE AT THE DRY END BEING LESS THAN DEFECTIVE LIMITS. THE DRYERS ARE CONTROLLED BY WET END MOISTURE AND DRY END COMPOSITE PROFILE MOISTURE. THE DRYERS ARE CONTROLLED SO THAT THE INHERENT LAG OF STEAM UNITS THEREIN IS COMPENSATED BY HEAT SUPPLIED BY TRIM DRYERS, HAVING FAST RESPONSE TIMES. TO DERIVE INSTANTANEOUS VALUES OF AVERAGE WET END BASIS WEIGHT, THE WET END GAUGE IS NORMALLY SINGLE POINTED AND ONLY PERIODICALLY SCANNED ACROSS THE SHEET.

Abstract: Disclosed is a system for measuring moisture content of a sample with a capacitive probe wherein a voltage controlled, semiconductor capacitor is employed for balancing out the probe capacitance when the probe is removed from the sample. The amount of unbalance produced by the presence of the sample is used as a measure of the moisture content. The probe, capacitor and a phase inverting means are mounted in a head positioned in proximity to the sample. At a remote location from the head and sample, AC and DC power sources are provided for exciting the probe and controlling the capacity of the variable capacity semiconductor, respectively. Monitoring means for variable signals derived from the capacitance measuring means is provided. Balance is attained manually or automatically, according to different embodiments. In automatic balancing, the probe output is modulated with a predetermined frequency which is phase detected to control the amplitude of the voltage applied to the semiconductor capacitor.

Abstract: Articles, such as cigarettes, are moved successively down a prescribed path past sensing and operating stations. Each article is categorized and the category, such as reject, is recorded in a respective memory cell of an addressable memory according to a memory-addressing signal formed as the difference between a counter signal and the address signal of the respective sensing station. When the article reaches the operating station, the recorded signal is read out from the respective memory cell by addressing it with a memory address signal formed as the difference between the counter signal and the address signal of the operating station. The readout signal is utilized to operate upon the article, as to reject a faulty cigarette from the path.

Abstract: A system for measuring weight per unit area using a nucleonic gauge with simplified standardization circuits. In one embodiment the standardization circuitry is all digital, and in another embodiment, is partially digital. In those two embodiments and a third embodiment the standardization circuitry is operated in accordance with the count of detector output pulses occurring during a predetermined interval during a standardization time. In the latter embodiment, this digital count signal is converted to an analog signal to vary the operating point pulse rate directly and the counting time inversely. In the other two embodiments, the digital count signal is employed to set a down counter to the corresponding count, and then the counter counts down for an interval of time. In one embodiment the analog of the digital count signal is employed to determine the count down time, while another embodiment utilizes the digital count signal itself to establish that count down interval.

Abstract: In one form the method of the present invention provides for the control of a material zone property where the property at one location in the zone is measured by a stationary gauge. The measured property is compared with a desired target property and the regulating apparatus is adjusted to change the measured location property to the desired target property. The target property is adjusted as a function of the difference between the average property of at least a portion of the material across the material width, including the measured location in the zone, and the measured location property to bring the average material property in the zone to the desired target property. One embodiment of control apparatus in accordance with the present invention comprises a gauge means for indicating the property at one location in a zone of the material and for indicating the property average at least partially across the material dimension including the location. A regulating means can be adjusted to vary the property in the zone. A controller means compares the location property indication with a target signal and actuates the regulating means to change the material property in the zone and reduce the difference between the target signal and the location property indication to substantially zero. Means is provided to offset or change the target signal as a function of the difference between the property average and one target signal representing a desired target property to another target signal representing a desired target property to another target signal to cause the controller means to compare the indicated property with another target signal that brings the average zone property to the desired target property.
