  • Patent number: 11946947
    Abstract: A method of validating a test for estimating the organic carbon content of soil or changes in organic carbon content of soil over time in which a first sample of soil is taken from a selected location and heated using Loss On Ignition (LOI) to remove organic carbon, the method comprising the steps of taking a further sample of soil from an adjacent location, the sample having minimal organic material content. A predetermined quantity of an organic material is added to the further sample to provide a second sample which is heated using Loss On Ignition (LOI) with the change of weight of the second sample determining whether the test of the first sample yielded a valid estimate of the organic carbon content of the first sample. Apparatus (10) for use in performing the method is also disclosed.

    Abstract: A method estimates the effect on the weighing result of a balance (1) that is caused by electrostatic charges on an object (2) received on a load receiver (6) thereof. A first predefined positive voltage (U1) and a second predefined negative voltage (U2) of equal magnitude are alternatingly applied to a first electrode (12) in the vicinity of the weighing object. The forces acting on a force-measuring cell (17) are measured and are registered as the first and second measurement results. The difference between the respective measurement results represents the magnitude of the influence that the electrostatic charges residing on the weighing object are having on the weighing result. The difference also represents an essentially proportional part of the force resulting from electrostatic charges on the weighing object which causes a change in the weighing result and is sent as a signal to a processor unit.

By providing such a method, the true contents (i.e. mass) of fluid in a pressure vessel such as a cylinder can be measured directly without the need to compensate for factors such as temperature or compressibility. This allows a determination of mass through direct derivation from the density of the gas in the cylinder, reducing the need for additional sensors or complex calculations to be performed.

  • Patent number: 8534144
    Abstract: A system to measure the internal state of a bundle of tubes by injecting a signal into each tube of the bundle, receiving reflections from the tube due to anomalies within the tube, then analyzing the reflections to determine the type or characteristics about the anomalies. The analyzed information is stored in database to be used for statistical processing. Further, the device can be used in the performance of a cleaning process by conducting an initial assessment of the tubes in a bundle of tubes, comparing the stored data and estimating the number of cleaning cycles that will be required, and re-conducting the evaluation of the state of the tubes after every cleaning cycle or after every few cleaning cycles.

  • Patent number: 8415967
    Abstract: A wafer inspection apparatus that performs surface inspection and internal inspection of solar cells using a single apparatus. The wafer inspection apparatus includes a loading unit configured to allow a cassette to be lifted up or lowered by an elevator. A surface inspection unit includes a plurality of stages, thus performing surface inspection of each wafer using a first vision module. A wafer transfer unit has a rotatably installed center portion and has both ends provided with adsorption parts. An internal inspection unit is configured such that a conveyor is installed to allow the wafer to be transferred, thus performing internal inspection of the transferred wafer through a second vision module. An unloading unit enables wafers having completed the internal inspection to be sequentially loaded onto the unloading unit. A control unit controls a series of wafer inspection procedures.
