  • Patent number: 8408051
    Abstract: A method for analyzing moisture content in an analyzer. In one embodiment a sample is introduced into an analyzer and an initial weight is obtained. The sample is then fortified where it is allowed to pick-up moisture. The temperature of the analyzer is increased and an initial fortified point is obtained wherein the sample has returned to its initial weight. Thereafter the analyzer obtains the final moisture content of the sample at a test finish time. In one embodiment satellite analyzers are biased against a standard analyzer so that more uniform results are obtained.

  • Patent number: 8408052
    Abstract: The invention relates to equipment for concentrating and analyzing components contained in a flowing medium, and an analyzing method applying said equipment. The analyzing equipment comprises a concentrator, including a porous sorbent bed, in which components can be absorbed or adsorbed from the medium flow, said bed being electroconductive, so that components can be desorbed to a washing flow by heating the bed with electric current; and to an analyzer defining the desorbed components, said analyzer being for instance a gas detector. According to the invention, the sorbent bed is in the flowing direction widened towards its outlet end, having for example the shape of a truncated cone. By means of the invention, the temperature in the sorbent bed is equalized by transferring heat in the washing flow towards the bed outlet end, which end receives a weaker heating effect per unit of volume, owing to the widening shape of the bed.

  • Patent number: 8111076
    Abstract: This invention is concerned with a method for measuring the canopy rehydration pulse during the period of water application. During the rehydration process water leaks from the trunk xylem tubes into the sapwood extraxyllary region. A water content sensor in this region monitors the magnitude and timing of this leakage water thereby giving a measure of the magnitude and timing of the upward flow of water. The rehydration pulse is quantified by a sequence of measurements of sapwood water content: an initial measurement of water content just prior to water application, then measurement of water content during water application. The difference between the values obtained in the two measurements yields a measure of the leakage water in the extraxyllary region and, in turn, the magnitude and timing of the rehydration pulse. Determination of the onset and termination of the rehydration pulse is used to optimize the duration of water application.

  • Patent number: 8109133
    Abstract: The invention concerns a method and a device for measuring the ability of a material to absorb a liquid, whereby a liquid is brought into contact with a surface of a test specimen (P) of the material, and wherein the amount of liquid that has been absorbed in the test specimen is calculated. A certain amount of liquid is supplied to a liquid chamber unit, which on one side is limited by said surface, such that an amount of liquid which is absorbed by the test specimen leaves the liquid chamber unit and a representation comprising an indication of the reduction of the amount of liquid in the liquid chamber unit is produced.

  • Patent number: 8104190
    Abstract: A moisture metering calibration method and system for, e.g., determining the moisture lumber within a lumber drying kiln is disclosed. Calibration of moisture indicative electrical signals obtained from, e.g., moisture sensing capacitive plates spaced apart within a stack of drying lumber is performed, wherein long lengths (e.g., up to 1000 linear feet or more) of coaxial cable can be used for transmitting the signals, and effectively removing signal anomalies induced in such cabling so that accurate lumber moisture measurements result. Such extended cable lengths provides flexibility with respect to placement of electronic moisture metering equipment. This flexibility allows such equipment to be placed in an environmentally-controlled enclosure, rather than on the weather exposed exterior of a kiln whose lumber is being monitored.

  • Publication number: 20120011922
    Abstract: A sampler improves sampling and moisture measurements by reducing the introduction of fines, providing a more representative grain sample, and improving the ability to make consistent moisture measurements. The sampler has a body positioned to receive grain from a grain flow path. A primary auger positioned within the body has a shaft and a fin configured to lift and propel a portion of the grain up to and through a sampling opening. A sensor assembly operatively connected to the body and in communication with the sampling opening is configured to receive the portion of grain indicate the moisture content of the portion of grain.

  • Patent number: 8091409
    Abstract: A storm water run-off percolation rate test system includes a turbid water generator having a silt or sediment source providing silt into a mixing tank. A pipeline carries turbid water from the mixing tank to a test pit or test site. A flow meter measures the amount of turbid water moved into the test pit. Detectors detect a water level in the test pit. A controller automatically controls the turbid water generator and flow of turbid water into the test pit, and records data on the amount of turbid water provided into the test pit over time, to determine a percolation rate. In a method for determining a percolation rate, turbid water is created and used in the percolation rate testing, to more accurately simulate run-off.

  • Patent number: 8056401
    Abstract: In-line systems for and methods of measuring the moisture content of ceramic material within an extrusion system used to form ceramic articles are disclosed. One method includes arranging, relative to the extrusion system, at least one radio-frequency (RF) sensor system having an RF antenna, and generating through the RF antenna an RF field that resides substantially entirely within the ceramic material. The method also includes, in response to the RF field interacting with the ceramic material, generating in the RF sensor system a signal representative of a raw moisture-content measurement of the ceramic material. The method also includes generating calibration data by performing RF moisture-content measurements on samples of the ceramic material having different known moisture contents, and establishing a calibrated moisture-content measurement using the raw moisture-content signal and the calibration data. Both contact and non-contact systems and measurement methods are described.

  • Patent number: 8051714
    Abstract: In a sensing instrument using a quartz sensor on whose front surface an adsorption layer for adsorbing a substance to be sensed is formed and which changes in natural frequency by the adsorption of the substance to be sensed, the present invention has an object to quickly detect a trouble of the quartz sensor to prevent an operator from recognizing an incorrect measurement result. In the present invention, a level detecting circuit detecting a signal level of an oscillation output of an oscillator circuit is provided, and after the time for stabilization passes after the power-on time, a computer takes a level detection value therein to compare the signal level and a threshold value. Then, when the signal level is lower than the threshold value, the signal level is determined as abnormal and, for example, the abnormality notification is displayed on a display unit, whereby an operator is notified of the occurrence of the abnormality.
