    Abstract: A sensor and method is provided for measuring one or more select components of a material. In one embodiment, a method measures the components by emitting electromagnetic radiation at the material and detecting the intensity of the emerging radiation at separate locations from the source. In another embodiment, a sensor provides a radiation source for emitting radiation at a sheet, a plurality of detecting means, wherein at least one detecting means is offset from the source, for detecting radiation after interaction with the sheet and first and second reflectors for directing the radiation so that the radiation makes multiple interactions with the sheet when moving from the source to the detecting means. The invention can accurately measure the select components (e.g., moisture) of different grades of paper by eliminating the effects of the scattering power and determining absorption power at each band of the spectrum considered necessary for a particular measurement.

    Abstract: An infrared web moisture sensor which is substantially temperature and basis weight insensitive comprises a source of infrared radiation for directing an infrared beam through the web and an infrared detecting unit on the other side of the web which measures the transmission of the infrared beam through the web at three separate wavelength regions. The transmission in the first wavelength region is primarily sensitive to the moisture content of the web. The transmissions in the second wavelength region is less sensitive to the moisture content. The transmission in the third wavelength region provides an indication of the web temperature. Temperature insensitivity is achieved by selecting the temperature response of a measurement band pass filter and a reference band pass filter based on the maximum basis weight and the maximum moisture content of the web and compensating for any remaining temperature sensitivity with a temperature correction band pass filter. Signals indicative of the transmission of infrared through the web in each of these regions are digitized and fed to the process control computer for the paper mill. The computer combines the values of the digitized signals, using an empirically derived equation, to produce a value indicative of the percentage of moisture in the web which value is not affected by changes in web temperature. The process control computer utilizes this result to control devices which selectively and moisture to portions of the web or selectively dry portions of the web, thereby producing a web having a desired moisture content profile.

    Abstract: The apparatus and method of the present invention provide means by which non-warped corrugated paperboard sheet may easily and consistently be produced. The cross-directional moisture content profiles of the top and bottom liners of the corrugated sheet are automatically monitored, and controlled with independently operable water jets such that the liners have approximately equal machine and cross-direction moisture content profiles. The moisture content profiles of the liners are controlled to equalize the machine direction and cross-directional stresses created within the liners as they dry out, thereby producing non-warped corrugated paperboard sheet.

    Abstract: An infrared paper web moisture sensor is described which comprises a source of infrared radiation for directing an infrared beam through the web and an infrared detecting unit disposed on the opposite side of the web from the infrared source. In one embodiment, the infrared detecting unit measures the transmission of the infrared beam through the web at three separate wavelength regions of the infrared spectrum, one of which is sensitive to web temperature. In a second embodiment, the infrared detecting unit measures the transmission of the infrared beam through the web at two separate wavelength regions of the infrared spectrum, one of which is insensitive to web temperature. For each embodiment, signals are developed indicative of the transmission of infrared through the web in each of these regions, digitized, and fed to the process control computer for the paper mill. The computer combines the values of the digitized signals, via an empirically derived equation, to produce a value indicative of the percentage of moisture in the web. The process control computer utilizes this result of control devices which selectively add moisture to portions of the web or selectively dry portions of the web to thereby produce a web having a uniform moisture content.

    Abstract: The present invention relates to methods of recovering energy materials, such as oil, shale oil or hydrocarbon gas, by providing limited combustion of these energy materials within an underground energy material reservoir and, consequently, thinning and mobilizing the energy materials such that their recovery is increased. The methods involve the injection into a borehole of an water/oxygen slurry which releases oxygen gas as it flows into the reservoir and recovering, at a later time following in-situ combustion and/or reaction, an improved energy material yield from said borehole or adjacent borehole.

    Abstract: A device for characterizing the formation of a sheet material is described. The device comprises a formation sensor for measuring the basis weight of the sheet material as the material passes through the sensor, and signal processing circuitry which receives a basis weight signal from the formation sensor and which produces three types of outputs, which outputs characterize: (1) the magnitude of variation in the sheet basis weight; (2) the strength of the weakest portion or portions of the sheet; and (3) the size of the flocs comprising the sheet. The formation sensor includes a light pipe that is held against the sheet as the sheet moves through the sensor, and that directs a small spot of light transmitted through the sheet to a light detecting device. The magnitude of small-scale variation in the sheet basis weight is computed by determining the ratio between average value of the basis weight signal and the varying or AC component of the basis weight signal.
