Abstract: A pneumatic stepper motor weight actuator (7) captures the advantages of polymeric harmonic gears while occupying less space and eliminating the problems associated with air entrapment in the stator grooves (31, 49). Air entrapment is eliminated by providing orificed air passages (47) from the bottom of the longitudinal stator grooves (31) to the center stator hole (45). Advantageously, the actuator (7) includes a rigid gear (23) comprising a toothed polymeric sleeve (61) adhesively bonded inside a metal cup (63).

Abstract: The stack reflectance is predicted from an on-line, wavelength dependent measurement of the sheet reflectance and the on-line measurement of the sheet opacity at a wavelength interval. The stack reflectance Rst is then used to predict and/or control stack color, preferably by using the parameter K/S = (1-Rst2)/2 Rst.

Abstract: A standard control signal for a web forming machine is temporarily interrupted and replaced by a perturbing signal or signals which are applied to one, a grouping, or all of a series of actuation cells of the web forming machine. One or more actuation cells are driven with an alternating perturbing signal(s) which generate a corresponding action in the actuation cell(s). The perturbing signal(s) alternates from a neutral position of the cell and is selected to minimize mean effects over any given period of time. The effects of the alternating signal(s) on the web appear within the area of the web which is affected by the actuation cell(s) such that the mapping and the response of the actuation cell(s) can be determined by monitoring that portion of the web which is formed while the alternating signal(s) is applied to the actuation cell(s). The mapping(s) and/or response(s) of the actuation cell(s) are obtained by correlating the perturbing signal(s) and a web property signal or profile signal obtained by monitoring the web formed by the machine. The perturbing signal(s) is defined by a pseudo-random binary sequence with multiple signals being selected to be statistically independent of one another. To ensure that the web is not perturbed beyond defined specifications, the perturbing signal preferably is gradually increased in amplitude and is terminated individually for each actuation cell upon reaching a usable amplitude.

Abstract: A two-speed stepper actuator (10) for rotationally driving a power nut (24) to adjust a slice lip spindle (20) linearly. A clamp for power nut (24) includes a bushing plate (32) driven by drive solenoid (D) which is mounted for rotation relative to power nut (24). A lever (40) is pivotally mounted on the bushing plate (32) and includes an eccentric locking cam surface (50) shaped for selective clearance of nut (24) when in the center or number 2 position and clamping engagement of nut (24) when in the opposite extreme 1 and 3 positions. A first amount of rotation of the lever (40) about its pivotal mounting (48) on said bushing plate (32) engages and locks lever end cam surface (50) against nut (24) and a second and additional rotation of the lever (40) then drives the nut (24). Three position solenoids (L) and (D) drive the bushing plate (32) and lever (40) independently and at different speeds due to an accommodation by spring (36) on pusher rod (34) of solenoid (L).

Abstract: A method and apparatus are disclosed wherein a plurality of basis weight sensors (120, 122, 124, 126, 128) are interleaved with one or more processing stations (104, 106, 108) used to conjoin or apply one or more layers (112, 116) to a base substrate (102) to form a multilayer product (118, 110) such that a sensor (120, 122, 124, 126, 128) is located on the input and output sides of each processing station (104, 106, 108). Each of the sensors (120, 122, 124, 126, 128) can be calibrated with a plurality of product calibrations such that multiple output signals corresponding to multiple products can be generated simultaneously by the sensors. Each of the sensors (120, 122, 124, 126, 128) is calibrated with product calibrations corresponding to the product (118, 110) or intermediate stage (114) of the product (118) which it monitors, the layer applied by the processing station preceding it, if any, and the layer applied by the processing station succeeding it, if any. Signals generated by the sensors (120, 122, 124, 126, 128) may then be used directly to determine the basis weight of the resulting product (118) and/or each intermediate stage (114) of the product, or the signals may be processed to determine the basis weight of each layer of material of the resulting product independent of the substrate (102) to which the layer was applied. Substrate independent layer measurement is performed by subtracting the output signal generated by the sensor preceding the processing station applying the layer based on the product calibration corresponding to the layer from the output signal generated by the sensor succeeding the processing station applying the layer based on the product calibration corresponding to the layer.

Abstract: A method and apparatus are disclosed wherein a web of material (116), such as paper, being manufactured or processed is monitored to generate a profile signal which is separated into a number of subprofile signals corresponding to a number of processing stations to be controlled. The contributions of the individual processing stations, such as headboxes (102, 104) for the manufacture of paper, to various cross direction (CD) profile characteristics of the web of material has been recognized as being spatial frequency dependent. Accordingly, the profile signal generated by monitoring the web of material is divided (142) into two or more subprofile signals corresponding to the processing stations based on the CD spatial frequencies characteristic of the operations performed by the stations. The subprofile signals are then applied to the processing stations (102, 104) to control them to maintain one or more desired CD profile characteristics. The division of the profile signal into subprofile signals can be performed by filtering, Fourier transforms or otherwise. Preferably, profile signal division is performed by a digital processor.

Abstract: Method and apparatus for measurement and control of an industrial process by detecting the average transmittance of a radiation beam which passes through the process material. A radiation source (28) having an intensity Io is positioned on one side of the material to be measured and a suitable radiation detector (32) is positioned on the other side. The transmitted radiation intensity, I, is measured by the sensor. An index Z commensurate with the degree of nonuniformity of the variable in the material is determined, and a process signal is generated from a quantitative relationship among I, Io, and the index Z. In a first embodiment implemented in a system for measurement and control of the basis weight of paper in a paper production process, the index Z is indicative of the nonuniformity of the material mass distribution in the sheet and is determined by measurements with a separate formation gauge operating on-line with, but independently of, the basis weight sensor. In a second embodiment of the invention implemented in such a paper making process, the index Z commensurate with the degree of nonuniformity for the mass in the material, is derived from the standard deviation of the detected radiation intensity signal, or the equivalent standard deviation of the basis weight output signal.

Abstract: A contacting thickness gauge comprising a unique surface follower (46). The bottom surface (56) of the surface follower (46) has both contacting areas (64,66) and non-contacting areas (62). The surface follower (46) is in substantially continuous contact with a moving sheet (2) and embodies an electrically conductive target having a target surface that intersects a magnetic field but is substantially free from contact with the sheet during normal operation. The surface follower (46) is designed to minimize damage to the sheet (2) that would otherwise occur from contact between the surface follower and a protruberance of the sheet, and to preserve the characteristics of the target surface.
