摘要： An apparatus for sensing three properties of materials: the conductivity or resistance, the dielectric constant, and the proximity of the material to the sensor portion of the apparatus. The apparatus includes a fixed impedance element coupled in series with the sensor portion of the apparatus between an input signal and ground. The sensor portion of the apparatus is an electrode configuration which includes at least two electrodes with a portion of the material residing between and in close proximity to the electrodes. The sensor exhibits a variable impedance resulting from changes in physical characteristics of the material. The fixed impedance element and the variable impedance of the sensor portion form a voltage divider network such that changes in impedance of the sensor portion results in changes in voltage on the output of the apparatus. The variable impedance of the sensor portion relates to changes in property of the material being sensed which can then be related to changes in other physical characteristics of the material such as weight, chemical composition, and temperature.

摘要： A system and method that combine an array of fast under wire water weigh sensors with a scanning system provides an accurate measurement of the entire sheet down to 1 in. by 1 in. resolution. Because CD profiles are obtained instantaneously, MD and CD variations are completely decoupled, even if CD profiles are taken at longer intervals apart. The technique allows monitoring the basis weight of a sheet of material that is formed in a process that employs a de-watering machine that includes a water permeable moving fabric supporting wet stock and a dry end which technique includes the steps of: a) positioning an array of water weight sensor elements (array) underneath and adjacent to the fabric wherein the array is positioned in a cross direction to the moving fabric; b) positioning a scanning sensor at the dry end to measure the dry basis weight of the sheet of material; c) operating the machine and measuring the water weights of the sheet of material with the array and measuring the dry basis weight of the sheet of material with the scanning sensor at the dry end; d) developing a functional relationship between water weight of the sheet as measured by the array and the basis weight of the sheet which is formed after being substantially de-watered; end; and e) periodically, adjusting the functional relationship using readings from the scanning sensor to compensate for variations due to process parameters. The technique can further include the step of correlating positional readings of the scanning sensor with measurements from the corresponding element in the array to obtain separate calibration for each individual element of the array and step e comprises adjusting the functional relationship obtained in step d and the calibration obtained in to compensate for variations due to process parameters.

摘要： A sensor apparatus and electrode configuration within the sensor apparatus for measuring electrical characteristics of an aqueous fibrous composition. The electrode configuration includes an elongated ground electrode and at least one segmented electrode to form an array of measurement electrode cells. The electrode configuration further includes an array of reference electrode cells formed by a plurality of reference electrodes built into the array of measurement electrode cells. The measurement electrode cells and reference electrode cells have a different sensitivity to water weight of the aqueous fibrous composition and the same sensitivity to conductivity of the aqueous fibrous composition. The measurement apparatus obtains simultaneous resistive measurements from both measurement and reference cells and determines the ratio of the measurements such that the affects from conductivity is canceled out of the measurement ratio. The determined measurement ratio is used to obtain a measurement of the water weight of the aqueous fibrous composition by using previously determined characterization data of the water weight vs. a range of measurement ratios.

摘要： A system and method of producing a paper product from a wetstock solution using a sensor for sensing resistive impedance changes of the wetstock on the support web of the system. The resistive impedance changes are used to measure physical characteristics such as water weight of the wetstock on the support web of a sheetmaking system. The system includes a fixed impedance element coupled in series with a sensor portion between an input signal and ground. The sensor portion is an electrode configuration which includes at least two electrodes with a portion of the wetstock residing between and in close proximity to the electrodes. The sensor exhibits a variable impedance resulting from changes in the physical characteristics of the wetstock. The fixed impedance element and the variable impedance of the sensor portion form a voltage divider network such that changes in impedance of the sensor portion results in changes in voltage which are measured, converted to impedance changes of the wetstock, and which are then related to water weight of the wetstock.

摘要： An improved basis weight measurement system which utilizes two means for irradiating a material to determine the distance from the radiating device to the material being surveilled and its mass per unit area. A portable, self-contained device applying this principle contains first and second radioactive emission means with corresponding detectors for each. A weaker emission is reflected back from the surface of the material to a detector, and a backscattered portion of a stronger emission is received by a detector after having penetrated the material. By virtue of there being two separately detectable emissions, the device can be used proximate the material being measured in order to perform the measurement without the need for direct contact between the device and the material. The measured basis weight is read directly from a digital Liquid Crystal Display, with the distance between the device and the surveilled material being indicated by Light Emitting Didoes. Another feature of the dual irradiation property of the device is that the speed of movement of the material does not deteriorate the accuracy of the measurement. Electronic memory and interface means are also provided for later transfer of data to a base computer and/or printer.

摘要： An apparatus for modifying an atmosphere for use in a conditioned zone of a structure. The apparatus typically includes an underground air conduit system to take advantage of geothermal conditions to modify the temperature of air and water vapor flowing through the apparatus. A drain is typically provided for removal of water vapor that condenses to liquid in the air conduit. In some embodiments air from the conditioned zone of the structure may be recycled through the apparatus, together with a source of air that originates outside the conditioned zone of the structure. The apparatus may be integrated into other heating and cooling systems as appropriate to further control the air temperature. The apparatus may be combined with a solar heated water heater or “trombe” wall type structure where the heat generation in the winter provides a complete balance for year round stable and livable air temperatures.
